Description

The present invention relates to a feeding device for feeding a punch rivet to a punch riveting device, a punch rivet device for setting a punch rivet with a punch force assisting vibration, which is in particular an ultrasonic vibration, and a method of punch riveting with such a punch riveting device with which a space saving and secure positioning of a punch rivet before the punch riveting on the punch riveting device is possible.

A punch riveting apparatus is used for joining or joining at least one component with a punch rivet. Here, either the two ends of a component by means of a punch rivet or more punch rivets are attached to each other. Alternatively, two or more components can be fastened together with a punch rivet.

For punch riveting, depending on the material of the component or components, very high process forces must be applied in order to set the punch rivet correctly. To reduce the energy consumption caused thereby during the operation of the system and to reduce the joining forces, in the meantime punching riveting in some cases an ultrasonic support is used. As a result, the punch riveting apparatus becomes smaller, slimmer, and lighter, which in turn has a better accessibility to a machined component flange or a joint result. In addition, there is an improvement of a Einschneid- / separation process, a reduction of delamination in the punch riveting, concretely in the cutting, of fiber composites and it is an extension of the rivetable material spectrum possible. In addition, there are cost advantages, such as lower consumption costs for the operator of the punch riveter with ultrasonic support. In particular, a shoring of cheaper stainless steel auxiliary joining elements is made possible. In addition, the advantages mentioned also entail lower equipment costs, since it is possible for the lighter punch riveting apparatus to use robots with a lower payload, possibly from standard robotic load classes.

The feeding of punch rivets to the punch riveting apparatus for performing a punch riveting operation causes problems, for example, with respect to the limited space of the punch riveting apparatus. In today's usual feeds the punch rivet is fed by mechanical elements directly to the punch riveting. The punch rivet is usually supplied from or in the stamp direction.

At present, the fixation of a punch rivet on a punch riveting apparatus is carried out prior to the punch riveting by means of mechanical devices in a webbing or as loose rivets with the aid of a profile tube.

A disadvantage of such a type of rivet feed is that the punch rivet for punch riveting must be held in position relative to the punch of the punch riveting. This also causes the correct centering of the punch rivet under the stamp difficulties.

Moreover, in the case of automation of a punch rivet with the punch riveting device, it is necessary to reduce the time for feeding a punch rivet to the punch riveting device compared to the previous solutions in order to accelerate the joining process as a whole.

Another problem arises from the fact that in the ultrasonic punching riveting vibration energy is introduced into the feeding mechanism. As a result, the punch rivet can not be held vibration-free at the intended position. In addition, the feeding mechanism is thereby claimed more than necessary. This leads to premature wear of the feed mechanism or forces a more complex design of the feed mechanism.

Therefore, it is an object of the present invention to provide a feeding device for feeding a punch rivet to a punch riveting device, a punch riveting device for setting a punch rivet with a punch force assisting vibration, and a method of punch riveting with such a punch riveting device with which the aforementioned problems can be solved , In particular, a feed device for feeding a punch rivet to a punch riveting device, a punch riveting device for setting a punch rivet with a punch force assisting vibration and a method for punch riveting are provided with such a punch riveting in which a simple, secure and quick fixation of a punch rivet to a compact built punch riveting is possible.

With the feed device described, the stamped rivet can be supplied both simply and reliably with a compact design of the stamped riveting device, so that rapid fixation of a stamped rivet on a compactly constructed stamped riveting device is possible. In this case, the feed device allows the punch rivet to be held in its correct position relative to the punch of the punch riveting device, so that the correct centering of the punch rivet under the punch is realized simply, safely and quickly.

Due to the very space-saving with the feeder for Stanznietvorrichtung supply and fixation of the punch rivets, the punch riveting builds even smaller, more compact or slimmer than before.

In addition, due to the reduced installation space and the feeding of the punch rivet outside the joint, the great advantage is that the punch rivet can also be placed in hard-to-reach positions on a component.

The described embodiment of the feed device for the punch riveting device also avoids the fact that vibrational energy is introduced into the feed mechanism during the ultrasonic punch riveting. This makes it possible to hold the punch rivet vibration-free at the intended position. In addition, the feeding mechanism is no longer claimed as required and therefore can be constructed less expensive without being more susceptible to wear.

In the figures, identical or functionally identical elements are provided with the same reference numerals, unless stated otherwise.

Fig. 1 shows very schematically a system 1 with a punch rivet 2. The system 1 may for example be a manufacturing plant for items 3, such as vehicles, furniture, electrical appliances, etc.

The punch riveting device 2 is used for setting a punch rivet 5 in, for example, a first component 6 and a second component 7, which rest on a die 10 one above the other. After setting the punch rivet 5 in the The stamped rivet 5 generates a riveted joint of the first and second component 6, 7. The first and second component 6, 7 may be components of the article 3. As described above, however, only two edges of one and the same component 6 can be connected to one another by means of at least one punch rivet 5.

Preferably, with the first and second component 6, 7 to add a combination of fiber composites or fiber reinforced plastic, preferably carbon fiber reinforced plastic (CFRP), with at least one metal, in particular ductile steel, or aluminum or magnesium and alloys of these materials. Application may find the method described below in aircraft, general vehicle, body lightweight, etc., especially for the industry of electromobility. Here are the following method high-quality joint connections between unequal lightweight materials, especially with carbon fiber reinforced plastics (CFRP) produced.

The punch rivet 5 may preferably be made of stainless steel or of V2A steel or of V4A steel in the materials mentioned. The materials mentioned contribute to the creation of the punch rivet 5 as little as possible harmful dusts.

In Fig. 1 For setting the punch rivet 5 in the first and second component 6, 7, a punch 20 with a vibration generating device 21 is provided. The punch 20 is guided in a hold-down 30 of the punch riveting device 2. The punch 20 is driven by means of a drive device 40, so that on the punch 20 a punch force F acts, which is in particular a punch pressure force. The drive device 40 may be an electric drive and a spindle with ball, roller or planetary screw drive. In addition, a converter 60 is provided which initiates a vibration S supporting the punch force F. The vibration S is provided by means of the vibration generating means 21 of the punch 20 for the punch rivet 5 and thus the component 6, 7. The Vibration generating device 21 may be, for example, a power ultrasonic vibration system consisting of piezo converter, booster and sonotrode, which generates ultrasound as the punch force F supporting vibration S.

In Fig. 1 FIG. 2 shows a state of a punch riveting method performed by the punch riveting device 2 in which the punch rivet 5 is disposed between the punch 20 and the first member 6. Subsequently, with the punch 20, the punching force F in the direction of the punch rivet 5 and with the vibration generating device 21, the stamping force F supporting vibration S in a range of, for example, 15 kHz to 20 kHz and an amplitude of for example 5 to 50 microns on the rivet. 5 be applied. In the following, the punch rivet 5 is first cut or punched into the components 6, 7, as in FIG Fig. 2 illustrated. If the stamping force F continues to be sustained and the oscillation force S assisting the stamping force F, the punched rivet 5 spreads in the components 6, 7 due to the back pressure from the die 10, as in FIG Fig. 3 shown. In addition, a slug 8 forms on the punch rivet 5 from the components 6, 7.

In the present embodiment, when the punch rivet 5 is set in the components 6, 7, as in FIG Fig. 4 shown, the punch force F and the punch force F supporting vibration S off.

The punch riveting device 2 can then be moved back to the starting position for punch riveting, which in Fig. 1 is shown. Thereafter, a next punch rivet 5 can be placed in the components 6, 7 or in at least one other component.

The punch riveting device 2 accordingly performs a punch riveting method for setting a punch rivet 5.

Fig. 5 shows, by way of example, a punch rivet 5 having a punch rivet head 51 and a punch rivet foot 52 symmetrical to a punch rivet axis 53 are. The punch rivet 5 is fed to the punch riveting device 2, as described below.

According to Fig. 6 Before the punch riveting, a feed device 55 is used for feeding the punch rivet 5 to the punch riveting device 2. The feeding device 55 has a receiving unit 56, which is designed as a recess. In the receiving unit 56, a positioning member 57 is provided, on which a punch rivet 5 is positioned. In addition, the feed device 55 has a movement unit 58. For feeding the respective punch rivet 5 to the punch riveting device 2, the punch rivet 5 is not inserted directly into the punch riveting device 2 or there into a so-called mouthpiece. Instead, the delivery of the punch rivet 5 takes place in the feed device 55, more precisely its receiving unit 56 with the positioning element 57.

The feeding of the punch rivet 5 into the feed device 55 takes place outside the actual joint or joining zone, in which the at least one component 6, 7 is joined. Since the movement unit 58 is designed as a rotatable and / or pivotable carrier, the movement unit 58 is then movable or driven, after feeding the punch rivet 5 into the receiving unit 56, between the punch rivet device 2 and component 6, 7, as in FIG Fig. 6 shown. As a result, the punch rivet 5 or the receiving unit 56 with the punch rivet 5 is positioned on the punch riveting device 2, more precisely its hold-down 30. The movement unit 58 is in this case preferably designed such that the receiving unit 56 is at least partially moved in a plane transverse to a punch axis 25 of the punch 20 between a loading point and a joint, which are shown in more detail with respect to the other embodiments. By such a movement, the feed device 55 is moved approximately parallel to the at least one component 6, 7.

As in Fig. 6 In addition, in the punch riveting apparatus 2, the die 10 has a recess 11 facing the component 7 for spreading the punch rivet foot 52 of the punch rivet 5. For punch riveting is the Punch riveting 2 with its hold-down 30 attached to the feeder 55, which in turn is attached to the component 6. As a result, the receiving unit 56 during punch riveting forms an extension of the hold-down 30, so that the receiving unit 56 carries the punch 20 together with the hold-down 30 during punch riveting.

In this case, the hold-down 30, the feeding device 55 and the die 10 are arranged axisymmetric to preferably the same axis, preferably the punch axis 25 of the punch 20. With the positioning member 57, for example as a ring or O-ring, in particular rubber ring, or at least two on the circumference the receiving unit 56 equidistantly arranged ring segments is executed, the punch rivet 5 can be positioned centered under the punch 20 of the punch riveting 2 and held securely.

As a result, the punch rivets 5 can be positioned and fixed on the punch riveter 2 for punch riveting both very easily and safely and quickly and with little space requirement. Here, space can be saved with the described embodiment on the component 6, 7 itself, since the loading of the feeder 55 takes place outside of the actual working space or the joint.

Fig. 7 shows very schematically a section through a punch rivet 2A and a feeding device 55A according to a second embodiment. The punch rivet device 2A and the feeder 55A are constructed in many parts like the punch rivet device 2 and the feeder 55 according to the first embodiment.

In contrast to the punch riveting apparatus 2 according to the first embodiment, in the punch riveting apparatus 2A, a hold-down 30A is formed at its end where the feeder 55A is to be attached, obliquely to the punch axis 25. In Fig. 7 For example, the pitch of said end of the blank holder 30A extends from inside to outside as an example. Complementary to this is the feeding device 55A on its receiving unit 56A formed. Thus, for punch riveting, generally, an inclined surface of the blank holder 30A is to be assigned to an inclined surface of the receiving unit 56A. Due to this mechanical configuration, the hold-down 30A and the feed device 55A, in particular their receiving unit 56A, can be arranged very simply and quickly relative to each other. As a result, the correct, in particular axisymmetric, positioning of the feed device 55A and the punch rivet 5 accommodated therein is always, and therefore very reliably, achievable at the hold-down 30A and thus at the punch rivet device 2A for performing a punch riveting operation.

By means of this configuration of the punch rivet device 2A, more precisely its hold-down 30A, and the feed device 55A, the punch rivet 5 is always located centrally under the punch 20 when the punch rivet 5 is positioned on the punch rivet device 2A. As a result, the punch rivet axis 53 is always preferably identical to the punch axis 25.

The punch rivet 5 can, as described above with reference to the first embodiment, be set into the components 6, 7 by the further process or method steps described above.

With respect to the description of the other features of the punch riveting apparatus 2A, reference is made to the description of the preceding embodiment.

Also on the punch rivet 2A, the punch rivets 5 can be both very safe and quickly positioned and fixed with little space required for punch riveting.

Fig. 8 shows very schematically a section through a punch rivet 2B and a feeder 55B according to a third embodiment. The punch riveting device 2B and the feeder 55B are constructed in many parts like the punch riveting device 2 according to the first embodiment.

In contrast to the punch riveting device 2 according to the first embodiment, in the punch riveting device 2B, a hold-down 30B is formed with a positive-locking element 31 at its end to which a feeder 55B is to be set. In the example of Fig. 8 the positive locking element 31 is formed as a recess in the hold-down 30B. In particular, the interlocking element 31 is formed as a triangular contour, as in Fig. 8 shown as an example. The positive-locking element 31 is designed, for example, as an annular groove running around the entire hold-down 30 or as at least one separate element on the hold-down 30. Complementarily, the feed device 55B is formed on its receiving unit 56B and has a positive-locking element 561. The positive-locking element 561 is accordingly on the receiving unit 56B a projection, which is adapted to the shape of the recess of the positive-locking element 31.

When the hold-down 30B and the feeder 55B are also abutted with each other by means of a moving means 58A, as in FIG Fig. 8 is shown between them, preferably releasable, positive engagement formed. Of course, it is alternatively possible to design the positive-locking element 31 as a projection and the positive-locking element 561 as a recess.

Thus, for the punch riveting, the interlocking element 31 of the hold-down 30B are assigned to the interlocking element 561 of the feeder 55B. By this mechanical configuration, the hold-down 30B and the feeder 55B can be very easily and quickly arranged to each other. As a result, the correct positioning of the feed device 55B and the punch rivet 5 accommodated therein is always and therefore very reliably achievable at the hold-down 30B and thus at the punch riveting device 2B for performing a punch riveting operation.

The punch rivet 5 can also be found by the design of the punch rivet device 2B, more precisely its hold-down 30B, and the feed device 55B always centered under the punch 20 when the punch rivet 5 is positioned on the punch riveting device 2B. As a result, the punch rivet axis 53 is always preferably identical to the punch axis 25.

As in Fig. 9 As shown in FIG. 2, the punch rivet device 2B is arranged on a device 70 as a further difference from the preceding embodiments. The punch riveting device 2B is disposed on a C-bracket 71 of the device 70. The punch riveting device 2B can be moved freely in space with the device 70. The device 70 can be designed as a robot. Alternatively, the device 70 is designed as a hand-held frame. In addition, the punch rivets 5 are fed to the punch riveting device 2B with the movement unit 58A, which can be used alternatively or in addition to a movement unit 58. The moving unit 58A moves the receiving unit 56B in a plane transverse to the punch axis 25 of the punch 20 between a loading point 85 and a joint 65, which in Fig. 10 are shown in a plan view of the moving unit 58A.

According to Fig. 10 For example, the moving unit 58A is configured as a rotatable disc or magazine rotatably supported about an axis 582. The moving unit 58A receives a plurality of receiving units 56B, as in FIG Fig. 10 illustrated more clearly. The receiving units 56B are each arranged at the same distance from the center of the disc formed by the shaft 582. The receiving units 56B are also arranged at the same distance from each other near the edge of the disc.

The punch rivets 5 are, for example, on one side of the moving unit 58A, which the right side in FIGS. 9 and 10 corresponds to the receiving units 56B supplied. This side of the movement unit 58A may also be referred to as a loading position or loading location 85. On another side, in FIGS. 9 and 10 is arranged on the left side, the punch riveting device 2 is at the joining position or Joint 65 is arranged. As a result, the loading of the movement unit 58A can be separated from the joining process.

Optionally, at least one of the receiving units 56B may be designed as a removable part. As a result, the movement unit 58A can be equipped, as required, with accommodation units 56B for the required rivet size or rivet shape of the punch rivet 5.

The receiving units 56B also preferably have a positioning element 57, even if this is shown in FIG FIGS. 9 and 10 not shown.

With the moving unit 58A, it is possible, for example, to bring the receiving units 56B pre-loaded with a punch rivet 5 to the punch riveting device 2B and to process several joining operations from the pre-loaded receiving units 56B on the moving unit 58A. Between the individual joining operations, the punch riveting device 2B and / or the movement unit 58A can move relative to each other. As a result, a very fast processing of joining tasks is possible.

Even with the punch riveting device 2B in conjunction with the feed device 55B, the punch rivets 5 can be both very safe and quickly fed and with little space required for punch riveting device 2B at the joint, positioned and set there.

Also in the third embodiment, the punch rivet 5, as described above with respect to the first embodiment, can be set in the components 6, 7 by the further above-described process or method steps.

Fig. 11 shows very schematically a section through a punch rivet 2C and a feeder 55C according to a fourth embodiment. The punch riveting device 2C and the feeder 55C are largely constructed like the punch rivet 2B and the feeder 55B according to the third embodiment.

In contrast to the punch riveting device 2B according to the third embodiment, in the punch riveting device 2C, a coil 35 is additionally provided on a hold-down 30C, which is traversed by an electric current I as required by driving by a control device 37. As a result, a magnetic force F _{M is formed} acting on a feeder 55C, more specifically, a magnetic portion 562 of its pickup unit 56C. Thus, by means of the coil 35, the controller 37, and the magnetic portion 562, a magnetic force F _M , which is a magnetic attraction force in particular, can be turned on or off, causing the hold-down 30C and the receiving unit 56C to be magnetic at their facing ends attract.

For example, the receiving unit 56C can also be designed as a replacement part with a short service life or durability if only slight forces are exerted on the joining partners, ie the components 6, 7, by the receiving unit 56C and the actual joining process by the punches 20 and / or the vibration generating device 21 takes place. Here, the receiving unit 56C may advantageously be made of plastic, which has the magnetic region 562 as a magnetic insert at its end facing the punch riveting device 2C.

In a modification of the moving unit 58 for the feeder 55C, the moving unit 58 is alternatively dispensed with, as in FIG Fig. 12 shown.

According to Fig. 12 In the case of the system 1, a device 70 is configured to pick up the receiving units 56 loaded or loaded with punch rivets 5 on a magazine 80 and to move them to a joint 65 with the punch riveting device 2. After setting the punch rivet 5 in at least one of the components 6, 7, the device 70 moves the receiving units 56 back, so that the receiving units 56 can be re-loaded or loaded with rivets 5. Thus, the device 70 moves the punch rivet 2C and additionally one of the receiving units 56 with or without punch rivet 5 in space, in particular between the component 6, on which the at least one joint 65 is arranged, and the magazine 80, in which the punch rivets 5 are mounted , The device 70 is thus a moving unit for moving the individual receiving units 56.

As in the previous embodiment, the device 70 may be implemented as a robot. Alternatively, the device 70 is designed as a hand-held frame. The device 70 is thus in the present embodiment part of the feeding device for feeding the punch rivets to the punching device 2C.

For picking up the respective receiving unit 56, the coil 35 is energized in each case, so that a magnetic force F _M acts between the punch riveting device 2C and the receiving unit 56C, as described above. When the receiving unit 56 is returned to the magazine 80, the current I for the coil 35 can be switched off again so that no magnetic attraction force acts between the punch riveting device 2C and the receiving unit 56C.

Even with the punch riveting device 2C in conjunction with the device 70, the punch rivets 5 can be both very safe and quickly supplied with little space required for punch riveting 2 at the joint, positioned and set there. Also in this way a very fast processing of joining tasks is possible.

With regard to the description of the further features of the punch riveting apparatus 2C, reference is made to the description of the preceding embodiments.

All of the above-described embodiments of Appendix 1, the punch riveting 2, 2A, 2B, 2C, the punch rivet 5, the Feeding means 55, 55A, 55B, 55C, the moving units 58, 58A, 70 and the method of setting a punch rivet 5 with a punch force assisting vibration may be used singly or in all possible combinations.
