Description

The invention relates to a tool slide.

Tool slides, which are also called wedge drives, are known.

Wedge drives are used in tools in metalworking, e.g. used in forming presses. Connected to these wedge drives are usually devices or tools that enable punching or other shaping. A conventional wedge drive has an upper guide part comprising a slide element and a slide guide element and a lower guide part comprising a driver element or vice versa. The wedge drives are moved on the part of the slide guide element by a drive which applies a generally vertical pressing force. On the part of the driver element, wedge drives are fastened in the tool or the press on a base plate on which the workpiece to be machined is also placed directly or via a corresponding support device.

From the DE 26 40 318 B2 is known a wedge drive for redirecting a vertical pressing force into a force acting at an angle for the forming process. This wedge drive consists of a driving wedge, on which a vertical force of a corresponding working press acts, and a slide wedge, which transfers the force to the horizontal. The driver wedge and the slide wedge either run over a rounded cooperating area or, in a further embodiment, over a roller.

From the DE 24 39 217 A1 a wedge press with a prism-shaped wedge guide is known, the contact surfaces are roof-like or gutter-like and the roof or gutter extends over the entire pressure-absorbing width of the wedge.

From the DE 23 29 324 B2 a wedge press with a device for preventing unwanted movements of the wedge with a prism-shaped wedge guide is known.

Typically, overhead wedge drives used in the body industry consist of a driver, a slide, and a slide seat. A vertical force acts on the top of the slide holder, which pushes the slide holder down. The driver is firmly anchored in the tool, so that when the slide holder is pressed, the slide anchored in the slide holder is pressed in any direction outside of the vertical working direction.

Wedge drives hanging above are often used. In this design, the slide hangs in its guide in the slide holder. The driver sits rigidly in the lower part and specifies the working direction of the slide. During the downward stroke of the press, the spring-loaded slide rests on the driver and is pushed in the working direction by the continuing slide holder over the driver surface.

The wedge drives known from this prior art have disadvantages, so that the slides used often have only a short service life and are subject to high wear due to their structural design. Therefore, they often have to be replaced after short running times because they show signs of wear, so that an exact deflection of the vertical pressing forces is no longer possible, which leads to unacceptable tolerances in metalworking.

From the DE 197 53 549 C2 a wedge drive is known which can be produced in a continuously industrial manufacturing process and is said to have a long service life. For guiding the slide in the slide receptacle, there are angle strips which are made of bronze and which have graphite sliding elements fitted in the angle strip. This wedge drive is generally equipped with a driver, a slide and a slide holder for deflecting a vertical pressing force, the driver having a prismatic guide and the travel path of the slide on the driver being shorter than the travel path of the slide on the slide holder and the ratio of the travel paths to one another is at least 1 to 1.5 and the angle α between the travel paths is 50 ° to 70 °. In the case of such a slide, the driver element has a prismatic surface, the flanks of the prismatic surface being formed sloping outwards. In addition, this wedge drive has forced return clamps on two opposite sides in respective grooves of the slide element and the driver element. In this way, in the event of a breakage of a spring element returning the slide element in its starting position, the slide element is brought back in the event of a spring breakage, and thereby preventing screwed-out punching elements from being torn out. The slide element is fastened to the slide guide element via the angle strips and retaining screws and can be moved along the angle strips with respect to the slide guide element.

From the US 5,101,705 A Another wedge drive is known, in which the slide element hangs on angle strips or by means of which it is fastened to the slide guide element. Here it is necessary that the plates lying against one another or the elements required for fastening are ground precisely in order to guarantee the running play required between the slide element and the slide guide element. With this wedge drive and also with the other known wedge drives, in which the slide guide element and slide element are connected to one another via angle strips and screws, it is disadvantageous that all tensile forces are introduced into the screws, which in particular at the moment when an expansion of the screws or of the surrounding material takes place, the running play of the mutually moving slide guide elements and slide elements is impaired. This subsequently leads to poorer stability, since the wear due to the clamping of the tool is particularly increased in this area. In addition, it proves disadvantageous that the slide element cannot expand laterally when heated, since it is narrowed in this regard by the angle strips. This can also lead to increased tool wear.

From the EP 1 197 319 A1 a wedge drive is known in which the slide element and the slide guide element are held together by means of guide clips. As a result, it should not be necessary to precisely grind in additional angle strips or other devices connecting these two elements in order to guarantee the necessary running play. In addition, the running play is not impaired even when the wedge drive or the tool heats up, since not only manufacturing tolerances, but also the expansion of the material that occurs can be absorbed by the connection via a guide clip. The stability of the wedge drive is therefore no longer impaired or shortened. Despite the fact that grinding is not necessary, a high level of running accuracy can be achieved. The guide brackets grip positively into the slide guide element, whereby the slide element hangs over the guide clips on the slide guide element via this positive engagement. As a result, it is not necessary to provide a hold on the slide guide element by means of screws which, on the one hand, are susceptible to wear and, on the other hand, can cause an already mentioned impairment of the running play when heated.

From the DE 10 2007 045 703 A1 a wedge drive with slide holder is known, a dovetail or prism guide device being provided between the slide element and slide element holder. In this publication it is stated that when a press tool, which is referred to as a working stroke, approaches approximately vertically, the slide element located in its rearward position rests on the rigidly standing driver element and is supported by the latter by means of its inclined position pointing in the working direction. The movable sliding element is thus only driven and pressed forward or outward by the press tool in order to be able to carry out the punching or forming work. During the rearward stroke, in which the press tool has exceeded its lower suction point and the two parts of which move apart again, the movable slide element is usually pushed back into its original position by means of an appropriately designed spring-elastic element, after which the process can be started again. It is stated that the retraction force required for the retraction of the slide element is usually between 2% and 10% of the actual work force and the weight of the slide element. For the size of the pressing force, the dimensions of the pressure-transmitting surfaces, which are referred to as sliding surfaces, should be the respective inclinations of linear guides in the Slider element receptacle and inclination of the driver element as well as the interplay of the surfaces and inclinations and the structure of the slider element itself are decisive. The pressures to be transmitted are usually between <100 kN to several 10,000 kN.

Furthermore, it is stated that the linear guidance in the slide element receptacle should guide the movable slide element without play and must endure high press forces and have to achieve long service lives. A tolerance of 0.02 mm is specified as the tolerance of the running accuracy of the movable slide element.

As already stated in the prior art, such wedge drives or slides consist of a slide assembly, which in turn consists of a driver, a slide part and a slide bed. Here, the slide part is fastened to the slide bed with holding elements, the slide part being slidably suspended between the driver and the slide bed. Corresponding bevels on the slide bed and driver are arranged inclined in opposite directions such that the slide part is "pushed out" between the two parts when the slide bed and driver move together. Since, as already stated, very large forces act here, appropriate guidance must be provided.

The known guides here are the cover strip guide, the guide with guide clips, the guide with guide columns and the dovetail guide ( DE 10 2007 045 703 A1 ).

The majority of these guides are attached to the outer surface of the slide. It must be determined here that the power transmission and the guidance are not optimal. On the one hand, the main slide guide must go over the sliding surfaces hereby be carried out offset so that less power transmission is possible. In addition, there is often a high space requirement and deformations caused by the introduction of operating forces (workers and retreating forces) could be determined.

A disadvantage of the known dovetail guide is that the game has to be reworked relatively often, which means that the slide must be completely uninstalled. The assembly and disassembly of all other slides is also very complex and time-consuming. On the one hand, this can only be carried out to the rear in the entire slide body, with large masses having to be moved with the help of a crane, in particular in the case of large slides, due to the high weight of the slide body and the very limited installation space, in a narrowly guided guide. With clamp slides, space must be provided for assembly and disassembly, so that an optimized position of the slider is not guaranteed for certain applications.

From the DE 10 2012 014 546 A1 A wedge drive is known, wherein the wedge drive is to have a sliding element receptacle, a movable slide carriage and a driver and is designed with sliding surfaces between the sliding carriage and the driver element, with at least one sliding surface being provided with a tensioning device which can adjust the pressing force during assembly of the Work tool simulated to produce a backlash between the at least one slide carriage and the at least one slide holder. According to this publication, a high tolerance accuracy is to be achieved, specifically in the slide upper part mounted in the tool, comprising the slide slide and the slide element receptacle on the one hand and the driver on the other hand, this being achieved by the fact that if the work tool is mounted on the slide, ie if the work tool, for example a hole punch, is attached to the slide, the slide is held together with the simulated pressing force.

A disadvantage of the known tool slides is that assembly and disassembly are very complex and time-consuming. On the one hand, such slides can only be mounted to the rear in the entire slider body, this being difficult in particular in the case of large slides due to the weight of the slider body, since very large masses have to be mounted in a narrow guide with the aid of a crane. In addition, the most widespread tool slides, namely slides with a clamp guide, require considerable lateral space for assembly and disassembly.

The object of the invention is to provide a slide guide which has optimized installation space and power transmission properties while improving the assembly capability.

The object is achieved with a tool slide with the features of claim 1.

Advantageous further developments are characterized in the subclaims.

According to the invention, a slide is formed with a slide bed, a slide body and a driver. Here, the slide body is mounted on the slide bed, a long extending groove being formed for mounting the slide body on or in the slide bed and a guide body 15 extending into this long extending groove, the guide body 15 sliding in the groove using suitable means is held so that a shift of the Guide body in the groove is possible. According to the invention, however, the guide body is not formed in one piece on the slide body, but rests in the slide body in a groove, this groove preferably having means at an end-side groove opening with which the guide body is axially fixed in the groove. In the transverse direction, the guide body 15 is preferably held in the groove in that the guide body has a thickening or widening along a longitudinal edge mounted in the slide body, so that it cannot be pulled out of the groove.

The guide body is preferably also thickened or widened along the longitudinal edge within the groove in such a way that the suitable means present in the groove likewise prevent it from being pulled out of the groove in the transverse direction. In this respect, the slide body and the slide bed are only axially movable relative to one another.

Of course, reverse storage is also possible and, in addition to a hanging slide, a standing slide is of course also conceivable in this configuration.

By removing the locking element at the end of the groove, of course, locking elements within the groove, z. B. adapters or the like conceivable - the guide body can be pulled axially out of the bearing in the slide body groove. As a result, the slide body and slide bed can be separated from one another in a simple manner and, in addition, z. B. in the event of wear, the guide body can be replaced.

According to the invention, in one embodiment, the slide guide between the slide body and slide bed is prism-shaped, in particular dovetail-shaped. In addition to In the prism-shaped or dovetail-shaped embodiment, however, the guide play can be adjusted according to the invention through an inclined surface, a separate sliding element being provided for this.

In detail, this guide is used in a known slide assembly consisting of driver, slide part and slide bed, the slide part being slidably suspended in the slide bed. Slide pairings are arranged between the driver and the slide part.

In a prism-shaped or dovetail-shaped design, for example, the slide bed has the dovetail-shaped recess for receiving the dovetail-shaped spring, a sliding element being formed on the outside on the dovetail-shaped spring and on the actual sliding surface. The sliding element is formed with a slope. This bevel can either be formed on the nut-side short surface of an L-shaped sliding element, then the groove is formed with a corresponding surface, in particular a corresponding inclined surface. However, the adjustment slope can also be arranged on the inner surface of the sliding element and thus act on the dovetail spring, which can then also be designed with a corresponding slope, but does not have to be. Here, both sliding elements or only one sliding element can have the slope. By sliding the sliding element along the direction of the slope (usually in the longitudinal direction of the elongated sliding strips), the guide play between the slide bed and the slide body is changed.

The L-shaped sliding element can also be formed from individual sliding elements which are L-shaped to one another, but this increases the assembly effort.

In particular, in the case where both sliding elements have the bevel, the sliding bed can also be adjusted relative to the sliding body by displacing the sliding strips in opposite directions.

According to the invention, the guide prism is not arranged in one piece on the slide part, but rather is mounted as a prism-shaped guide body above the slide part and can be removed from the slide part above.

As a result, the prismatic guide can be pushed in and removed from the rear, as a result of which the slide part can then be easily lifted off the slide bed or vice versa.

According to the invention, this guide body can even be designed with regard to the material in such a way that it develops sliding properties, since the separation of the prismatic guide body from the slide part according to the invention allows the materials used overall to be better matched to their use.

A tool slide 1 according to the invention has a slide bed 2, a slide body 3 and a driver 4.

The slide part 3 is arranged hanging on the slide bed 2 in the case shown, wherein the slide part 3 can be lifted off by the driver 4. The driver 4 is usually arranged in a first (in the case shown, the lower) half of the tool, while the slide part 3 is arranged over the slide bed 2 on a corresponding second (upper) tool half (not shown).

The slide bed 2 is approximately box-shaped and has an elongated rectangular groove 5, 5 screw holes 6 being provided for receiving corresponding screws (not shown) in addition to the elongated rectangular groove. The groove and the adjacent surfaces 7 delimiting the groove form a bearing surface for L-shaped slide strips 8, which rest on the surfaces 7 and extend into the groove with an L-leg 9. The L-shaped slide strips 8 have mounting holes 10 for screwing in mounting screws for arrangement in the screw holes 6. The L-shaped slide strips 8 have inclined surfaces 11 pointing towards the center of the groove, with which they delimit a prismatic space between them. Towards the slide body 3, the L-shaped slide strips have slide surfaces 12 which are flat and perpendicular to an X-axis 13 shown. The slide body 3 has sliding surfaces or sliding strips 14 corresponding to the surfaces 12, which act as sliding partners the L-shaped slide strips 8 are formed. A guide body 15 extends upwards into the groove 5 symmetrically to the vertical axis between the slide strips 14. The guide body 15 has, for example, a guide prism 15 which has elongated prismatic surfaces 16 with which it bears on the surfaces 11 of the L-shaped slide strips.

The guide body 15 is in this case designed as an elongated, rail-like or web-like component which extends prismatically into the area projecting into the groove 5 and is mounted in the slide body 3 with a T-shaped area 30. For this purpose, the slide body 3 has a T-shaped groove 31 which, adjacent to the sliding surfaces 14, has a narrower area 32 which opens out at the surface and widens away from the surface to form a T-shaped area 34. Accordingly, the guide body 15 has a narrower web-like area 35, which widens correspondingly in a T-shape to a crossbar-like area in the wider area of the groove.

In a modification of the exemplary embodiment shown, any other shape which widens from a narrower area to a further area, for example in relation to, can be used instead of an approximately T-shaped configuration for the safe guidance and holding of the guide body 15 in the slide body 3 the longitudinal extension of the guide body in cross section roundish rod-shaped widening, a triangular or prismatic widening and the like.

Accordingly, the guide prism 15a, which is arranged in the groove 5, can also have shapes other than a prismatic shape, as long as it is ensured by widening is that a hanging arrangement of the slide body in the slide bed is guaranteed.

Facing the driver, the slide body has further slide strips 17 which are arranged obliquely with respect to the X-axis 13 and correspond to prismatic guide surfaces 18 of the driver 4. The strips 17, since they are connected to the slide body, form removable slide strips which are brought into operative connection with the surfaces 18 when the upper tool part and the lower tool part are moved together.

Since the guide surfaces of the L-shaped slide strips 8 and the corresponding surfaces 12 of the strips 14 are arranged perpendicular to the X-axis 13 and are also arranged perpendicular to the guide prism 15, this embodiment is referred to as a so-called flat guide.

The slanted corresponding sliding elements 17, 18 between the slide body and driver form a so-called prismatic guide.

In a further advantageous embodiment ( Fig. 2 , same parts are provided with the same reference numerals), the tool slide 1 also consists of a slide bed 2 and a slide body 3 (the driver 4 is not shown).

The slide part 3 is arranged hanging on the slide bed 2 in the case shown, wherein the slide part 3 can be lifted off by the driver 4. The slide bed 2 is approximately box-shaped and has an elongated groove 5, the groove 5 having groove side walls 19 which run convergingly and thus form a dovetail groove section. The groove 5 bounding surfaces 7 converge with one another and run approximately perpendicular to the groove side walls 19 or parallel to the respective surfaces of the groove bottom 5a. L-shaped slide strips 8 lie on the surfaces 7 and extend into the groove with a narrow, short L-leg 9. The L-shaped sliding strips have contact surfaces 11 towards the surfaces 7 and sliding surfaces 12 towards the slide body 3, which are flat and diverging with respect to a vertical axis. These surfaces 12 slide on corresponding sliding surfaces 14 of the slide body 3.

The sliding surfaces 14 of the slide body 3 are accordingly inclined roof-shaped, with the guide prism 15 of the slide body being arranged symmetrically in the center in relation to the vertical axis, the prismatic surfaces 16 being formed adjacent to the short L-shaped legs 9 of the slide strips 8. The surfaces 16 and 14 enclose the same angle as the surfaces 9, 12 and are approximately perpendicular to one another in the example shown.

At the in Fig. 2 Partial sectional view shown shows that the guide body 15 is secured in the groove 31 by axially pulling it out by means of a cover plate 36 with screw 37, the screw 37 being screwed into the slide body and the disk 36 parts of the groove 31 and the guide body 15 stored therein covered. This fuse is also in one embodiment Fig. 1 intended.

Instead of a cover plate 36 with screw 37 for securing the guide body 15, a positive locking piece 40 is present in a further advantageous embodiment. The closure piece 40 is flattened cylindrical and has a bayonet-like closure with two opposite bayonet springs 41 and a projecting flange 42 on a second level. The bayonet springs 41 are in particular arranged on curved jacket walls 44 of the closure piece 40, while the projecting flange 42 is formed at a free end and projects beyond a flattened wall 45 of the closure piece 40.

The bayonet-like lock with the springs 41 engages in a groove 46 and thus secures components arranged behind it (e.g. spring, guide piece) on different contact surfaces.

For example, the spring can be secured once in the center of the closure piece and on the projecting flange.

The bayonet lock is designed in such a way that the bayonet-like geometry on the first level is released by rotating the lock piece 40 at a certain angle (e.g. 90 °), i.e. the springs 41 get out of the groove 46, and the closure piece can then be removed in the direction of arrow 43 from the assembly position.

The closure piece 40 is designed to be self-locking in the mounting position by means of a resilient pressure piece 47, which is arranged in particular in a bore 48 in a radial peripheral wall 49 of the projecting flange 42. In the assembly position, the resilient pressure piece 47 engages in a notch or bore 50 arranged opposite one another, so that a rotation of the closure piece 40 is only possible through an increased effort.

Depending on the requirements, the guide body 15 can be formed from a material which is made of the usual cast material of the slide body 3 deviates. Depending on the expected forces, z. B. Forged steels are used.

Of course, it is also possible to make the guide body hardened, to coat the guide body with hard material layers (for example in the PVD process) in order to achieve particularly high wear resistance.

Since an exact fit and guidance of the tool slide is necessary in particular between the slide bed and the slide body, the guide of the slide body in the slide bed must be adjustable or the slide strips 8 and the prism 15 must be adjusted to one another.

For this purpose ( 3 to 6 ) The mounting holes 10 in the slide strips 8 are designed as elongated holes, so that they can be moved along the mounting screws 20 and thus along an adjustment direction 21.

Moving the slide strips 8 along the direction 21 does not change any gaps or spacings that may be present between the surfaces of the slide strips 8 or the L-legs 9 and the guide prism 15. The contact surfaces 11 therefore run in relation to the longitudinal extent or the directions 21 the L-leg 9 of the L-shaped slide strips 8 obliquely. This means that they change their thickness in relation to the longitudinal extent. For example, the slope has an incline of 1-5 degrees.

The oblique contact surfaces 22 on the L-legs 9 of the L-shaped slide strips 8 are directed to corresponding corresponding surfaces 16 of the guide prism 15.

Moving in the direction 21 thus has the effect that, due to the inclined surface 11, the distance between the L-legs 9 and the surfaces 16 is reduced or eliminated. Both slide rails 8 and only one slide rail 8 can be moved here.

To adjust the play, a wedge-like or wedge-shaped bevel between the inside surfaces 22 of the L-legs 9, d. H. of the surfaces 22, which are directed towards the groove side walls 19. In addition, the groove side walls 19 - at least in the area where the surfaces 22 abut - can be designed with corresponding wedge-like or wedge-shaped bevels. A displacement along the direction 21 has the effect that the slide strips 8 are moved towards the guide prism 15 or are moved away therefrom. Since this is at the same time an approximation of the slide bars or removal of the slide bars in the transverse direction, d. H. in the direction 23, the elongated holes 10 are designed such that a floating mounting around the screws 20 is also possible in the direction 23.

In order to adapt the slide strips 8 to the guide prism 15 and thus also to adapt the exact position of the slide body in the slide bed, it is possible, for example, to position the screws (20) in the elongated holes 10 ( Fig. 5 ) the setting can be made. With this open setting ( 5, 6 ) there is, for example, a gap 25 between a groove center 24 of the guide prism 15 and the corresponding wall of the slide strips 8.

Now the L-shaped slide strips 8 are moved in the direction 21 so that the elongated holes and the screws z. B. are in a middle position ( Fig. 3 ), is hereby through the inclined surfaces 22 of the gap 25 ( Fig. 4 ) decreased.

With a tool slide with a flat guide ( Fig. 1 ) can also be used to set a production-related offset between the slide bed with slide part in the slide upper part and the driver in the lower part ( 9 to 11 ).

For this purpose, the slide bed with slide part is mounted on the tool with play between the slide strips 8 and the guide prism 15. The gap dimensions between the corresponding surfaces of the L-legs 9 and the guide prism 15 each have a first gap dimension. After placing the guide strips 17 on the driver 3, a manufacturing-related offset between the slide bed with slide part and the driver is compensated. The slide centers itself. In this centered state, the L-shaped slide strips 8 can then be moved even further, so that finally the guide play or the gap dimensions are eliminated in the mounted state. This ensures that the smallest tolerances are set even when the press is closed due to the movable slide strips.

The invention relates to a tool slide, comprising at least one slide bed 2 and a slide body 3, wherein the slide part 3 on the slide bed 2 is axially movable to a limited extent and wherein a groove 5 is formed on the slide part 3 or on the slide bed 2 and a guide body 15 of the corresponding means Slider part 3 or the slider bed 2 is axially displaceably slidably mounted in the groove, the guide body 15 being rail-like or slat-like and with a partial width in the slider body 3 or in the slide bed 2 is arranged in a groove 31 inserted.

The invention further relates to a tool slide, the guide body 15 having a thickening or widening 34 along a longitudinal edge mounted in the slide body.

In addition, the invention relates to a tool slide, the guide body 15 widening from a narrower web-like area 35 to the longitudinal edge 26 in a T-shape to a cross-bar-like area 36.

The invention also relates to a tool slide, the guide body 15 being fixed in the region of an axial mouth of the groove 31 in which it is fixed by a locking means 36, 37 against axial displacement.

The invention further relates to a tool slide, the guide body 15 being designed as an elongated rail-like or web-like component, the guide body 15 being designed to expand prismatically into the area projecting into the groove 5, a guide prism 15a being formed in the groove 5 is supported, the guide body 15 having prismatic surfaces 16 being mounted on corresponding surfaces 11 of slide strips 8 in the groove 5.

It is advantageous in the invention that an easy assembly and disassembly option is created by the guide body which can be removed and inserted by pushing it out to the rear or to the front.

Claims (9)

1. Tool slide, having at least one slide bed (2) and one slide body (3), wherein the slide part (3) is axially moveable on the on the slide bed (2) in a limited way, and wherein a groove (5) is formed on the slide part (3) and a guide body (15) is mounted in the grooves of the slide part (3) and the slide bed (2) to axially moveably slide on the slide bed (2) as a corresponding means, wherein the guide body (15) is of a rail- or batten-like design and is arranged with one part width in the slide body (3) or in the slide bed (2), inserted in a groove (31), wherein the guide body (15) is fixed against axial displacement in the area of an axial opening of the groove (31) in which it is fixed with a locking means (36, 37).
2. Tool slide according to claim 1, characterised in the guide body (15) has a thickening or widening (34) along a longitudinal edge mounted in the slide body.
3. Tool slide according to claim 1 or 2, characterised in that the guide body (15) widens from a narrower bridge-like area (35) towards the longitudinal edge (26) in a T-shape to form a cross-beam type of area (36).
4. Tool slide according to one of the preceding claims, characterised in that the guide body (15) is designed as an elongated rail - or batten-like component, wherein the guide body (15) is designed to widen prism-like in the area protruding into the groove (5), wherein a guide prism (15a) is formed, which is mounted in the groove (5), wherein the guide body (15) is mounted on the corresponding surfaces (11) of slide bars (8) in the groove (5) with prism-like surface (16).
5. Tool slide according to one of the preceding claims, characterised in that a positive locking securing piece (40) is present for securing the guide body, wherein the closure piece (40) has a bayonet-like closure and cooperates with corresponding bayonet closure on the slide body (3).
6. Tool slide according to claim 6, characterised in that the closure piece (40) has two opposing bayonet springs (41), each of a design that cooperates with a groove (46) each in the slide body (3).
7. Tool slide according to one of the preceding claims, characterised in that the closure piece (40) is cylindrically flattened and the bayonet springs are arranged on the curved sleeve walls (44) of the closure piece (40), whilst a cantilevering flange (42) is formed at a free end of the closure piece (40) and protrudes further than a flattened wall (45) of the closure piece (40), wherein the closure piece (40) secures components arranged behind the same (for example spring, guide piece) by lying against different abutment surfaces.
8. Tool slide according to one of the preceding claims, characterised in that the bayonet closure is designed in such a way that a twisting of the closure piece (40) at a certain angle releases the bayonet-like geometry on a first level, i.e. the springs (41) protrude from the groove (46), so that the closure piece (40) is arranged to be removable from an installation position.
9. Tool slide according to one of the preceding claims, characterised in that the closure piece (40) is arranged in a self-securing way in the installation position by means of a sprung pressure piece (47), which is arranged in a bore in a radial circumference wall (49) of the flange (42), wherein the sprung pressure piece (47) in a notch or bore (50) lying opposite in the installation position, so that a twisting of the closure piece (40) is possible only with increased force effort.
