Be configured in the flange on this shaft of rivet, this flange
Have at least one be similar to smooth downside and
Have acting surface for instrument with the opposed front of described downside,
Be used for producing at parts the riveting point in hole, described gun rivet should be installed on these parts, and has
The working position that is used for the central authorities of deformation process,
Form in the recess of described working position in the shaft of rivet, and so construct and arrange this working position, thereby cause the zone of the front of the described shaft of rivet below the downside of described flange to deform by instrument in the traction action that this working position produces
It is characterized in that, the working position of described central authorities is used for the tractive bolt is installed, and this tractive bolt does not form the parts of described gun rivet.
The invention still further relates to other preferred improvement project.
Constructed by the gun rivet of the present invention's proposition and known gun rivet, but the difference between them is not have the instrument mandrel of tractive in the above by gun rivet of the present invention similarly.The substitute is, such as the end at the dorsad flange of rivet sleeve a kind of structure is arranged in the described shaft of rivet, this structure makes described distortion become possibility.This structure can realize by specified bending place, along the longitudinal direction slit or similar structure.The instrument that is used for the arrangement gun rivet then acts directly on this position of the shaft of rivet.
Such as in improvement project of the present invention, can in the described shaft of rivet, form the working position of central authorities in the end in hole.In order to be limited in the distortion that has each other on sheet material to be connected and the opposed one side of the flange described shaft of rivet such as two, meaningfully, construct the hole of the boring form in the described shaft of rivet so dark, so that it roughly stops in the zone that is between rivet sleeve and the riveting point.
Can stipulate in improvement project of the present invention, described working position section of narrowing down in the hole in the described shaft of rivet forms.The section of narrowing down like this can be configured for the acting surface of the expansion of tractive instrument.
Especially can stipulate, the working position of described central authorities is configured to tension ground and connects the tractive bolt.This is such as can so carrying out, so that described working position forms the surface of extending transverse to longitudinal axis, the tractive bolt can be welded on this surface by resistance welding or by cold welding.
Described riveting point is used for having each other sheet material to be connected to produce described hole, and this riveting point especially can be the constituent element of the one of the described shaft of rivet.
But can arrange so equally and such arrangement is in the scope of the present invention, namely described riveting point is parts that separate, are connected with the described shaft of rivet.Because described riveting point when producing rivet head towards described shaft of rivet imposed load, so sometimes do not need to propose higher requirement to being connected between described riveting point and the shaft of rivet by the mounting type of described tractive bolt.
If described riveting point is parts that separate, it can be such as having be used to the ring surface that is resisted against on the described shaft of rivet at its back side towards the described shaft of rivet so, central projection has been constructed at described riveting point in inside at this ring surface, and this projection is engaged in the hole of the described shaft of rivet and connects ground or frictional connection ground is fixed on there such as power transmission.
Especially can stipulate, described riveting point carries out pretreated material in the mode that is different from the described shaft of rivet and makes by a kind of material that is different from the described shaft of rivet or by a kind of.
By the means of fixation of described tractive bolt on described gun rivet, advantageously, the cross section of the sleeve segment of the described shaft of rivet has the external frame that is different from circle.Can arrange so equally, the smooth downside of the flange of the described shaft of rivet own has the projection of sawtooth or other cusped edge, and the projection of described sawtooth or other cusped edge stops the described shaft of rivet to reverse with respect to the sheet material of its connection in this way.
The present invention has proposed a kind of method for settling blind rivet equally.
In method,
The gun rivet that will be provided with suddenly the riveting point is packed in the element until the downside of the flange of this gun rivet is resisted against on the upper side of this element,
The tractive bolt is inserted in the recess of described gun rivet until this tractive bolt is resisted against on the working position of described gun rivet,
Described tractive bolt is connected with described gun rivet,
The described tractive bolt of tractive is used for making the rivet distortion, and
After the zone broadening of the front of the described shaft of rivet with described tractive bolt from described gun rivet separately.
As mentioned above, in the method, the gun rivet that is provided with the riveting point is packed into suddenly such as injecting in the element until the downside of its flange is resisted against on the upper side of described element.Meanwhile or subsequently the tractive bolt is inserted in the recess of the shape with boring of the described shaft of rivet, until it especially touches the described shaft of rivet in the end regions of described recess.There, described tractive bolt is connected with the described shaft of rivet.Subsequently, described tractive bolt is pulled out from described recess, this just causes the part of the front of the described shaft of rivet to deform, and wherein the part of this front has enlarged its diameter.If the zone of described front is stretched in the opposed one side of described element, this zone will be out of shape to form rivet head so.Form in other words described rivet head in case realize distortion, that just unclamps described tractive bolt from the described shaft of rivet.Described tractive bolt can use in the next time instrumentation that carries out with next root gun rivet once again.
Described tractive bolt is the part that can be used for the instrument of arrangement gun rivet.
Connection between described tractive bolt and gun rivet can be such as setting up by cold welding.For this purpose, described tractive bolt with the contacted process of the working position of the described shaft of rivet in can be placed among the rotation, this will cause welding.
Another kind of connectivity scenario is, carries out the welding of resistance welding or capacitor discharge between the described shaft of rivet and tractive bolt.For this reason, power supply can be arranged in the placing tool.In this case meaningfully, described tractive bolt with respect to described gun rivet in the zone of its outer side surface be the isolation and only can touch its end face.
The another kind of scheme that is used for connecting is, described tractive bolt has self-drilling tip and screws in the end of the inside in the hole in the shaft of rivet in the zone of the end of its front.For this purpose, described tractive bolt can be placed to rotatablely move, this rotatablely moves directed in opposite direction after the tractive bolt is pulled out, and is used for described self-drilling tip is screwed out from the shaft of rivet once again.
Meaningfully, the motion of the tractive of described tractive bolt is supported with respect to the flange of the described shaft of rivet.Should realize this point thus, namely pulling force does not act on the connection between the shaft of rivet and the sheet material.This point namely produces pulling force such as reaching in the following manner between supporting member and described tractive bolt in instrument.
A kind of device for settling gun rivet of the same proposition of the present invention, this device has
Be used for keeping the support of gun rivet,
At least in front be the feeding body of tubulose in the zone,
Be used for making the driving mechanism of the unexpected feeding of described feeding body,
About the tractive bolt of described feeding body coaxial arrangement,
Be used for the feeding of described tractive bolt and the driving mechanism that retracts,
For the mechanism that described tractive bolt is connected with the working position of the recess of described gun rivet,
Be used for unclamping the mechanism of the connection between described tractive bolt and gun rivet.
As previously mentioned, it is the feeding body of tubulose that this device has for the support that keeps gun rivet and zone at least in front, and this feeding body can pass through the unexpected feeding of driving mechanism.This unexpected feeding is used for described gun rivet is at first injected described two boards material.In addition, described device comprises the tractive bolt, and this tractive bolt can be fed into mating face in the recess of described gun rivet by driving mechanism always and contact.This feeding needs not be unexpected.In addition, be provided with bindiny mechanism, be used for the end face of described tractive bolt with its front is connected with the end of the recess of the shaft of rivet.So construct described driving mechanism for the tractive bolt, so that it can be with the described tractive bolt of larger power tractive after connecting, wherein said power is supported on the described feeding body, and this feeding body then is resisted against on the front of described flange.

Embodiment
Fig. 1 shows the sectional arrangement drawing by gun rivet of the present invention.Described gun rivet comprises the shaft of rivet 1, is configured to rivet sleeve 2 in this shaft of rivet 1 zone therebetween.Constructed flange 3 at the described shaft of rivet 1 on an end therein, this flange 3 has smooth restriction face at its downside 4.Described downside is the side towards the direction of riveting point 6.4 opposed with described smooth downside, be configured to smooth equally or be similar on the smooth upper side 5, be provided with the acting surface for placing tool.
At the described riveting point 6 of the end of flange 3 dorsad structure, reduce continuously until a real most advanced and sophisticated 6a at the cross section of the shaft of rivet described in this riveting point 6.In the described shaft of rivet 1, constructed the recess 7 that namely has columniform shape of cross section such as the shape with boring.This recess 7 stops in the bottom as working position 8, this bottom then by around the wall body 10 of otch 9 and described recess 7 separate.
The instrumentation of this gun rivet so carries out, so that this gun rivet is arranged in the support of instrument.Figure 2 illustrates at the part of placing tool 11 and the corresponding relation between the described shaft of rivet 1.Like this this gun rivet of location is so that the most advanced and sophisticated 6a of described riveting point 6 is placed on two blocks of sheet materials 13 of placing up and down, 14 the surface 12.This two boards material 13,14 should be connected to each other by described gun rivet.On the upper side of the dorsad described rivet sleeve 2 of described flange 3, a part of having placed described placing tool 11.This part is feeding body 15 at this, and this feeding body 15 is configured to tubular in this zone, namely includes coaxially a boring 16 in the centre.This feeding body 15 impacts the head of the described shaft of rivet 1 by the driving mechanism of unexpected work, and makes the shaft of rivet pass described two boards material 13,14 with its most advanced and sophisticated 6a and 6 by this impact.Consequently, the downside 4 of described flange 3 is resisted against on described two boards material 13,14 the upper side 12.In this process, slightly distortion in following sheet material 14 edge region.Figure 3 illustrates this only makes the described shaft of rivet pass the result of the first instrumentation of described sheet material.The sleeve (referring to Fig. 4) of laying that described feeding body is surrounded lies on the surface of described sheet material.Unnecessary energy imports described laying the sleeve from described feeding body thus, only must absorb a small amount of energy so that the flange of described gun rivet 3 flushes when settling at it.
Now, boring 16 motion that in another job step, makes tractive bolt 17 pass described feeding body 15, this tractive bolt 17 has the external diameter more smaller than described boring 16.This tractive bolt travels forward, until it is resisted against on the bottom of recess 7 of the described shaft of rivet 1.There such as connecting 18 by resistance welding.For this purpose, described tractive bolt 17 is isolated along its outer side surface, and only its end face is exposed.An electrode of voltage source is such as being carried on the shaft of rivet 1 of described metal by described feeding body 15, and another electrode of voltage source is carried on the described tractive bolt 17.In case described tractive bolt 17 touches the bottom of described recess 7, that just produces by welding and connects 18.
Subsequently, as by the arrow 19 among Fig. 5 illustrates with respect to as described in tractive bolt as described in feeding body 15 tractives.By this traction process with described riveting point 6 towards described two boards material 13,14 tractives, wherein said rivet sleeve 2 is as deforming in the back side 20 of two boards material as described in being in the situation on the common blind rivet and the zone between the bottom.As a result of, as shown below Fig. 5 as described in the back side of two boards material form rivet head 21.
Now also described tractive bolt 19 must be unclamped from the bottom of described recess 7.This can be such as being undertaken by applying another this mode of pulling force that is enough to destroy described connection 18.This power must be destroyed less than meeting the power of described rivet head 21 certainly.Another kind of scheme for separating described connection 18 is, reverses now described tractive bolt 17.Produce thus the gravity that described connection 18 is unclamped.In this case, meaningfully, the described shaft of rivet 1 has non-circular cross section in the zone of described rivet sleeve 2, and perhaps the downside 4 of described flange 3 also can have projection, sawtooth or similar structure, is used for preventing that the described shaft of rivet from together rotating.
As a result of, produced the riveted joint between the described two boards material 13,14, the one side 12 at described two boards material in this riveted joint exists described flange 3 and exists described rivet head 21 in opposed one side 20.From the upper side of described flange 3, there is there the hole of central authorities.
In mode of execution illustrated with regard to this respect, the described shaft of rivet 1 is the parts of an one, and wherein, described riveting point 6 is extensions of described rivet sleeve 2.Fig. 7 shows another kind of scheme of how to construct the described shaft of rivet now.Here described rivet sleeve 22 is real sleeves, and this sleeve has the inside opening of a perforation.On the end of the dorsad described flange 3 of described rivet sleeve 22, the riveting point 25 of in this rivet sleeve 22, packing into and making as the parts that separate.This riveting point 25 has dorsad its most advanced and sophisticated 6a, ring-type, a smooth restriction face 26, and this restriction face 26 is corresponding to the end of the ring-type of described rivet sleeve 22.At the centre projection 27 that has been shaped, its external diameter is slightly greater than the internal diameter of described rivet sleeve 22.Described riveting point 25 can be assembled in the described rivet sleeve 22 in this way.Reach thus fixing.Connection between the projection 27 of described tractive bolt 17 and described riveting point 25 is with carrying out with mode identical in the mode of execution by Fig. 1 to 6.Described projection 27 also can stretch in the described rivet sleeve further, reaches in case of necessity the acting surface 5 of described gun rivet always.At this meaningfully, described projection does not have in described rivet sleeve or only contacts wall body with less power, because this projection should be pulled with respect to described rivet sleeve.
Fig. 8 shows for the device of settling gun rivet according to method described herein.Described device comprises shell 30, and this shell 30 has and be used for similar structure and the profile of common arrangement utensil of bolt.Can support along the longitudinal direction feeding body 15 in described shell, this feeding body 15 is made in Fig. 4 and is mentioned.Described feeding body 15 comprises driving mechanism 31, and this driving mechanism 31 so consists of, thereby can in unexpected travelling forward described feeding body 15 be moved with respect to described shell 30, is used for making described gun rivet pass described two boards material.This driving mechanism 31 can such as moving in the blast mode, can be arranged the cylinder 32 of getting angry for this purpose in described shell 30.In described feeding body 15, in unshowned supporting structure, can arrange movably along the longitudinal direction described tractive bolt 17 equally coaxially.Described tractive bolt 17 need to be not driven in unexpected travelling forward, because it only must touch the working position on the bottom of described recess 7.But it must have driving mechanism, and this driving mechanism retracts described tractive bolt 17 with very large power, because this power must be enough to make the zone of the described two boards material of passing of the described shaft of rivet to deform.This driving mechanism can be such as realizing by spiral motion.
Side arrangement in the zone of the front of described shell 30 magazine 31, in this magazine 31, placed many gun rivets, these gun rivets move in the support near the front, work end of described feeding body 15 by spring.
