Definitions
- the invention relates to a threaded nut made of metallic material with a threaded bore and a longitudinal axis radially circumferentially associated with the inner groove.
- the invention covers a method for producing the nut and a tool developed for this purpose.
- a nut of this type is to be taken from the German Patent 3 05 761, wherein the mother is provided with an annular cavity to form a safety nut, which is done by a drill on a machine tool with rotating spindle, wherein the spindle with a chuck for holding the Nuts in singular or plural aligned during excavation.
- the cavity is formed before the thread is cut.
- the cavity is equidistant from both end faces of the nut.
- the thread is cut on both sides of the cavity with equal pitch. Thereafter, the nut is subjected to a pressing in order to achieve an offset of the threaded parts on both sides of the cavity to each other.
- the Swiss Patent 2 49 469 indicates a lock nut, which is provided at its unloaded end with a groove by separating a portion of the thread, so that an annular flap is formed, which is submerged after the main part of the thread. Also by a Sich ceremoniessschraubmutter is provided.
- German patent 4 90 889 describes a securing effect of a nut, which is achieved in that in the threaded bore, or in the core of the nut, an annular groove with a wedge-shaped cross-section is attached. Also in this case the continuous thread is interrupted in the upper part of the nut by a recess which is designed so that thereby a thin wall is produced, so that an upper section acts resilient. Thereafter, the upper portion is compressed by compression in diameter and at the same time compressed in height to achieve an adhesion of the nut. The remaining through the recess thin wall piece creates a resilient effect on the narrowed and pitch offset pitch diameter of the upper threaded part.
- the inventor has set the goal of creating an efficiently usable and especially in a simple and fast way producible nut.
- annular collar is integrally formed on one of the end faces of the screw nut and bent in the axial direction so that it delimits a receiving slot which is directly associated with the portion of that end face surrounding the threaded bore as a support surface.
- the cross-sectionally deformed annular collar forms a polygonal plan, which is determined by wall surface sections.
- send - screw a form collar whose outer surface extends at a radial distance from the paraxial edges of the wall surface portions of the nut;
- the receiving slot is arranged near the outer surface of the mold collar and the latter preferably provided with a cross-sectionally achsärts curved outer surface.
- the two parallel edge edges offering receiving slot should be inclined cross-sectionally at an angle to these marginal edges;
- the annular collar is bent cross-sectionally so that the receiving slot is open towards the threaded hole. That is, the marginal edges of the receiving slot are spaced from the threaded bore.
- the annular collar is bent cross-sectionally in the axial direction such that the receiving slot is closed towards the threaded bore. That is, the marginal edges of the receiving slot are practically to each other to the threaded hole.
- a thread formed in the end region of the bent molded collar is offset from the remaining thread of the screw nut, so that the inventive effect of a fuse when screwed onto a bolt or screw is produced by a resilient force acting against the thread flanks of the bolt or screw.
- the offset of the curved shape in the forehead area kxagens attached thread relative to the remaining thread of the nut is relatively small and is possibly only a few tenths of a millimeter, for example 1 or 2 tenths of a millimeter, which is sufficient to produce the effect of the invention.
- such an offset as recognized by the invention, practically reachable only by the invention axially curved ring collar.
- annular collar-and correspondingly the molded collar-to extend in sections along the circumference of the screw nut.
- adjacent portions of the annular collar / collar are interrupted by an interruption, e.g. an incision or other cleft completely or partially separated from each other.
- a single section may have a more advantageous spring action for a particular use as compared to a molded collar extending along a full circumference of the nut.
- the inventive method for producing a nut specifies that an annular collar having a circular free upper edge is integrally formed on an end face of a blank nut corresponding to the plan of the screw nut and is curved cross-sectionally through an axially led to the latter pressure tool to the longitudinal axis of the blank nut.
- the free upper edge of the annular collar is circumferentially parallel introduced to the adjacent end face of the blank nut and arranged at a distance to this.
- the annular collar is upset in an end region at its upper edge during deformation, so that that end region has a larger cross-section than the adjoining region of the molded collar.
- an internal thread is cut or otherwise formed in an axial hole channel of the blank nut, in particular also in the front region of the bent molding collar. In order to complete the nut, the latter is to be offset in the rest of this after molding of the internal thread towards this.
- Edge edges of the receiving slot are spaced from the threaded hole or on each other. The offset causes a resilient clamping force on the thread flanks of a bolt or screw when screwing with the nut.
- a suitable tool for carrying out the method comprises in a housing a guide channel for a plunger, which ends at a receiving area formed by a ring edge of a tool face for a workpiece; the plunger is axially displaceable in the guide channel.
- that ring edge should have a cross-sectionally inwardly to the end face inwardly curved inner surface, which influences the curving of the annular collar during the pressing process.

- the length of that diameter d of the plunger 12 - and thus of the pressure end 15 - is dependent on the diameter of a hole channel described below a blank nut 52.
- the plunger 12 slidably supports in a guide channel 16 of a sleeve-like housing 20, the axial length h is given here with 78 mm with an outer diameter c of about 22 mm.
- the diameter e of the guide channel 16 running in the housing longitudinal axis A is slightly larger than the diameter d of that pressure piston 12.
- annular collar 24 is integrally formed on the outer surface 22.
- certain diametrical plane D terminates on the one hand the guide channel 16 containing base portion 28 of the housing 20, which merges at that level D in a - the mentioned mouth edge 32 offering - head portion 30 of the housing 20 .
- the guide channel 16 - opens the guide channel 16 - forming an annular inner stage 17 as a stop counter-member for stop plate 14 - in a him continuing axial channel 18 whose length is determined by that axial distance n of the annular collar 24 from the mouth edge 32 and the head portion 30th of the housing 20 extends.
- the wall thickness z of 3 mm of the head portion 30 is less than the wall thickness Z 1 of about 5 mm of the base portion 28.
- the annular collar 24 has in its near the base portion 28 a region inclined to the latter annular surface 25.
- the free end of the base portion 28 of the housing 20 is determined by an annular edge 34 of height i of about 4 mm, from whose annular edge 36 extends toward the longitudinal axis A out at an angle w of about 25 ° inclined inner surface 38.
- This inner surface 38 ends at a cross-sectionally inclined to the longitudinal axis A end face 40 of the housing base portion 28th
- the housing 20 or its annular edge 34 is axially assigned in FIG. 1, a workpiece 50 made of a metal material. These are the blank of a blank nut 52 hexagonal plan of the - determined by two end faces 54, 54 t of the blank nut 52 - axial height q of about 10 mm. Between six - in itself ebenflambaigen - wall surface portions 56 of the blank nut 52 extending in the workpiece longitudinal axis E a hole channel 58. At the recognizable in Fig. 3 upper end surface 54 - under limitation of an inner ring-like support surface 55 - parallel to the axis of an annular collar 64 of Height q 1, for example, 5 mm and small wall thickness t formed, the free top edge 66 is circular in plan.
- the workpiece 50 resting on a base area sketched at Q is coaxially fed to the pressure die 12 of the tool 10 in such a way that its pressure face 15 is that bearing surface
- FIG. 6 illustrates the end region 81 of the inclined shaping collar 74, which is subjected to an upsetting during the forming, whereby at the free end an upsetting bulge 84 is formed, which is wider in cross-section than the shaping collar 74 itself; these cross-sectional differences are not shown in Fig. 10 for reasons of clarity.
- an outer shoulder 82 of the radial width r between the paraxial wall surface portion 56 and the outer surface 76 of the mold collar 74 can be seen, which is the portion of the mentioned upper end surface 54; the illustrated radial width r of the outer shoulder 82 exists only on the paraxial edges 57 of the wall surface portions 56.
- the above-mentioned insert ring which is held clamped as a ring member in the receiving slot 78 and achJerts the peripheral edges 80 projects beyond and arranged in a screw hole 62 screw pin or the like. abuts as a holding and / or sealing member. Depending on the function, the latter is made of rigid or of limited flexibility material.
- the annular collar 64 is thread-free on its inner side facing the hole channel 58.
- the annular collar bears on its inner side facing the threaded bore 62, ie in the end region 81 a thread.
- the thread in the end region 81 is offset from the rest of the internal thread 60 with a slight offset, in the present case 1 to 2 tenths of a millimeter.
- the mold collar 74 is thus "bent" against the arrowhead direction S and snaps after reaching the correct thread measure in the thread flanks of a bolt or screw thread - this, however while maintaining a certain tension, which is achieved by the offset of the attached in the end region 81 of the bent axis ring collar 64 thread and which causes a corresponding acting in the direction of arrow S with S spring force.
- a closed between the nut and a bolt or a screw screw is secured against opening.
- FIG. 11 to FIG. 14 show a screw nut in which-otherwise as in the preceding FIGS. 1 to 10-screw nut-in a modification of the annular collar 64, cross-sectionally so on is bent, that the receiving slot 78 is closed to the threaded hole 62 out.
- the marginal edges 80 of the receiving slot 78 for the threaded bore 62 abut each other.
- the receiving slot 78 has a cross-sectional drop-shaped boundary visible in FIG. 14, so that now the peripheral edges 80 running on the receiving slot 78 are rotated according to the angle k 'in a modification of the angle k in Fig. 10 - are inclined to each other.
- a complete juxtaposition of the marginal edges 80 of the receiving slot 78 to the threaded hole 62 can be achieved by the mold collar 74 to the internal thread 60 toward, as explained, the internal thread 60 is formed both in the end region 81 and in the remaining nut.
- the final displacement of the molding collar 74 is achieved in this case a last, according to the offset slight bending or insertion of the molding collar 74.
- an offset can be made larger, while in the embodiment shown in FIG. 14, a securing, resilient force can be achieved due to the stronger bending of the molded collar 74.
- the offset can be in the range of 1 to 2 threads. In the example of FIG. 10, the offset is 1.5 threads. In the example of FIG. 14 at 1 thread.
- the receiving slot adjacent end portion 81 of the mold collar 74 is thicker than its subsequent cross-section, which - as shown in Fig. 6 - is comparatively thin and thus can be easily bent and by the processing and making the screw easier.
- FIG. 15 shows a modified embodiment of a workpiece 50 'in comparison with FIG. 3, which, like the workpiece 50 shown in FIG. 3, can serve as the basis for a screw nut according to FIGS. 5 to 14.
- the annular collar extends only in sections along the circumference of the workpiece 50'.
- three sections 64 ' are provided, which are completely separated from each other by three interruptions in the form of column 65, formed on the end face 54 of the workpiece 50'. As described above (FIGS. 5, 6), sections 64 'may be bent axially to obtain a nut according to the concept of the invention.
