Description

The invention relates to a crimping tool replacement device and to a method for exchanging a first crimping tool arranged at a process position in a crimping press for another second crimping tool.

Fig. 11 shows a crimping press 10 according to the prior art. In the crimping press 10, a crimping tool 50 is arranged. The crimping tool 50 comprises a mushroom-shaped holding pin 13 at the upper end of the crimping tool 50, which is arranged in the movable tool holder 11 of the crimping press 10. The crimping press 10 also includes an immovable lower tool holder 19.

Different crimping tools are required for different crimp contacts or different purposes, so that the crimping tool in the crimping press has to be exchanged for another crimping tool.

Manual replacement of the crimping tool with another crimping tool is usually error prone and slow. In addition, as a rule, it is not ensured that the newly inserted crimping tool is arranged in the crimping press at the same position as the replaced crimping tool (previously arranged in the crimping press). Therefore, typically, after replacement of the crimping tool, the position of the crimping tool or crimping contact or cable must be realigned. This is usually time consuming. During alignment, the operation of the crimping press is interrupted. This typically leads to high costs.

The invention is based on the object to provide a device or a method by means of which a crimping tool installed in a first crimping tool can be technically easily replaced by a second crimping tool.

This object is achieved by a crimping tool replacement device according to claim 1 and a method for exchanging one at a process position in a crimping press arranged first crimping tool against another second crimping tool according to claim 10 solved.

In particular, the object is achieved by a crimping tool replacement device for exchanging a first crimping tool arranged in a process position in a crimped crimping press for connecting a conductor end of a cable with a crimping contact against a second crimping tool, wherein the crimping tool exchanging device at least two exchange places for holding each having a crimping tool, wherein the exchange locations can be arranged in a first exchange position such that the first crimping tool from the process position on a first of the exchange places along a first direction of movement, in particular linear, is movable, the exchange places from the first exchange position to a second exchange position such are linearly movable, that located on the first of the exchange places first crimping tool and located on a second of the exchange places second crimping tool in a e second movement direction, which differs from the first direction of movement move, and the exchange places are so arranged in the second exchange position, that the second crimping tool from the second of the exchange places in the process position in a third direction of movement, which is opposite to the first direction of movement, movable is.

One advantage of this is that the first crimping tool can usually be exchanged in a technically simple and fast manner for the second crimping tool, which is not identical to the first crimping tool. It is also advantageous that the crimping tool replacement device typically occupies little space or volume and requires little space during the replacement process. In addition, it is ensured that the second crimping tool is placed in the same position as the first crimping tool, namely the process position, in the crimping press. As a result, a realignment of the crimping tool or of the crimp contact or of the cable is typically not necessary. This usually saves time. In addition, the crimping tool replacement device can be retrofitted to existing conventional crimping presses.

The crimping tool replacement device may include a guide device, in particular a T-shaped guide track, for guiding and holding a holding pin of the first Crimping tool and for guiding and holding a second holding pin of the second crimping tool during the process of the first crimping tool and / or the second crimping tool. As a result, the crimping tool or the crimping tools are usually guided in a particularly secure manner during the replacement or process. An advantage of this is also that the retaining pin of the crimping tool of the upper tool holder of a conventional crimping press is typically supplied at the same level. This further simplifies the exchange. In addition, the crimping tool can normally be brought even more safely into the process position. The retaining pin may be a mushroom-shaped retaining pin at the upper end of the crimping tool.

The at least two exchange locations may comprise at least two replacement tables for holding one crimping tool in each case such that the first of the exchange locations is arranged on the first exchange table and the second of the exchange locations is arranged on the second exchange table. As a result, the respective crimping tools are typically kept particularly secure during replacement. This improves the safe performance of the replacement process.

The crimp tool exchange device may comprise a first locking device for releasably locking the first crimping tool at the first exchange location and / or a second locking device for releasably locking the second crimping tool at the second exchange location. One advantage of this is that the crimping tool (s) can be kept particularly secure during replacement. Slippage of the crimping tool relative to the associated exchange position, even during the movement of the exchange positions from the first exchange position to the second exchange position, is typically prevented with particular certainty.

The crimping tool changing device may include at least one moving device for moving the first crimping tool and / or moving the second crimping tool and / or for moving the exchanging places and / or locking the first crimping tool to the first exchange place and / or the second crimping tool to the second exchange place exhibit. As a result, the replacement process can typically be carried out automatically. Manual intervention is not necessary during the replacement process. This allows the replacement process as a rule be carried out particularly quickly and safely. A further advantage is that the movements or the method of the crimping tools are typically carried out with particular precision. This makes even more sure that the second crimping tool is placed at exactly the same process position in the crimping press on which the first crimping tool in the crimping press was previously placed.

In one embodiment, the crimping tool replacement device is designed such that the respective crimping tool is exchangeable together with crimping contacts associated with the respective crimping tool. The advantage of this is that not only the crimping tool can be exchanged very quickly and technically, but also the crimp contacts. As a result, the crimping press can typically be used particularly flexibly. In addition, this usually saves time and consequently costs, since the operation of the crimping press is interrupted only very briefly.

The crimping tool can be movable in each case together with an adapter plate on which the respective crimping tool is detachably immovably fixed, and the adapter plate can be releasably fixed in such a way that the crimping tool detachably mounted on the adapter plate is arranged in the process position. An advantage of this is that the crimping tool can typically be mounted on the adapter plate at different positions. This serves to align the crimping tool with respect to the crimping press or crimp contact. Fixed immovably fastened means that the crimping tool can not be moved or displaced relative to the adapter plate when the crimping tool is fastened to the adapter plate, but at the same time the attachment is detachable, so that after releasing the attachment, the crimping tool can be displaced relative to the adapter plate (in order to fix the crimping tool in a different position on the adapter plate). The adapter plate can always be fixed in the same position with respect to the crimping press, so that the crimping tool fixed on the adapter plate is fixed at the process position.

The crimping tool replacement device may comprise a platen on which the first replacement table in the first exchange position and / or the second replacement table in the second exchange position partially rest and on which the crimping tool is arranged in the process position. An advantage of this is that, as a rule, the process the crimping tools can be made even safer and faster. The replacement tables are each supported particularly safe, so that essentially no vibrations or other unwanted movements of the exchange tables occur.

The support plate may have guide elements and a stop member for aligning the crimping tool in the process position. One advantage of this is that it is ensured that the second crimping tool is typically placed at exactly the same process position where the first crimping tool was previously located. In addition, the process of crimping tools is usually even safer. This allows the process to be carried out particularly quickly and precisely.

In particular, the object is also achieved by a method for exchanging a first crimping tool arranged at a process position in a crimping press for another second crimping tool, wherein the crimping press for crimped connection by means of the crimping tool arranged at the processing position, which has a conductor end of a cable with a crimp contact The method comprises the steps of: providing the second crimping tool at a second exchange location of at least two exchange locations of a crimping tool replacement device while the exchange locations are in a first exchange position; moving the first crimping tool along a first direction of travel from the process position to a first exchange location of the crimping tool replacing device, moving the exchange places with the first crimping tool and the second crimping tool linearly from the first exchange position in FIG a second exchange position in a second movement direction different from the first movement direction; and moving the second crimping tool from the second exchange station of the crimping tool exchange device to the process position along a third movement direction opposite to the first movement direction while the exchange places in the first movement direction second exchange position.

An advantage of this method is that the first crimping tool is typically exchanged with the second crimping tool, which is not identical to the first crimping tool, in a technically simple and rapid manner. It is also advantageous that the crimping tool replacement device usually occupies little space or volume and requires little space during the replacement process. In addition, it is typically ensured the second crimping tool is placed in the same position as the first crimping tool, namely the process position, in the crimping press. As a result, a realignment of the crimping tool or of the crimp contact or of the cable as a rule is not necessary. This saves time. In addition, the crimping tool replacement device can be retrofitted to existing conventional crimping presses as a rule.

The travel movements of the first crimping tool and / or of the second crimping tool and / or of the exchange locations can be carried out by at least one movement device. As a result, the replacement process is carried out automatically. Manual intervention is typically unnecessary during the replacement process. As a result, the replacement process is carried out particularly quickly and safely. Another advantage is that the movements and the procedure of the crimping tools are usually carried out particularly precisely. This makes even more sure that the second crimping tool is placed at exactly the same process position in the crimping press on which the first crimping tool in the crimping press was previously placed.

In one embodiment, the first crimping tool is attached to a first adapter plate and the first crimping tool is moved together with the first adapter plate and the second crimping tool is attached to a second adapter plate and the second crimping tool is moved along with the second adapter plate. An advantage of this is that the crimping tool can be mounted on the adapter plate at different positions. This serves to align the crimping tool with respect to the crimping press or crimp contact. The adapter plate can always be fixed in the same position with respect to the crimping press, so that the crimping tool fixed on the adapter plate is fixed at the process position.

The respective crimping tool can be moved with respective crimp contacts for connection to the conductor end of the cable. An advantage of this method is that not only the crimping tool can be replaced particularly easily and quickly, but also the crimp contacts. As a result, the crimping press can usually be used particularly flexibly. In addition, this typically saves time and consequently costs, since the operation of the crimping press is interrupted only very briefly The first crimping tool can be locked at the first exchange location by means of a first locking device and / or the second crimping tool can be locked at the second exchange location by means of a second locking device. One advantage of this is that, as a rule, the or the crimping tools are kept particularly secure during replacement. Slippage of the crimping tool relative to the associated exchange position, even during the movement of the exchange positions from the first exchange position to the second exchange position, is typically prevented with particular certainty.

A retaining pin of the first crimping tool and / or a retaining pin of the second crimping tool can be guided during the method in a guide device, in particular a T-shaped guideway. As a result, the crimping tool or the crimping tools are guided particularly securely during the replacement or process. An advantage of this is also that the retaining pin of the crimping tool of the upper tool holder is usually fed at the same level of a conventional crimping press. This further simplifies the exchange. In addition, the crimping tool can be brought even more safely into the process position. The retaining pin may be a mushroom-shaped retaining pin at the upper end of the crimping tool.

Fig. 1 1 shows a perspective view of a first embodiment according to the invention of the crimping tool replacement device 60 with crimping tools 50, 51 and crimping press 10. Fig. 2 shows a perspective detail view of the crimping tool replacement device 60 from Fig. 1 , Fig. 3 FIG. 12 is a perspective view of the crimping tool replacing device 60. FIG Fig. 1 without crimping tools and without guideway. Fig. 4 shows a perspective view of a support plate 25 of the crimping tool replacement device 60 of the Fig. 1-3 , And Fig. 5 shows another perspective detail view of the crimping tool replacement device 60 Fig. 1 ,

The crimping tool replacing device 60 serves to replace a first crimping tool 50 with a second crimping tool 51, the second crimping tool 51 being non-identical to the first crimping tool 50. The crimping tool 50 is installed in a crimping press 10. The crimping press 10 makes a crimped connection between a conductor end of a cable and a crimp contact 70 by means of the crimping tool 50, 51. The crimp contacts 70 may be different from each other. For different crimp contacts 70 different crimping tools can be used.

The crimping press 10 comprises an upper tool holder 11, in which a holding pin 13, 13 ', which is located at the upper end of the crimping tool 50, 51, is received. The retaining pin 13, 13 'may be mushroom-shaped.

The crimping tool replacing device 60 is mounted on a conventional crimping press 10 (by means of attachments 16 and the guide device). Therefore, the crimping tool replacement device 60 can also be used with previously known crimping presses or previously known crimping presses can be retrofitted.

The crimping tool 50, 51 comprises an anvil. The crimp contact 70, which is to be fastened to the conductor end of a cable, is aligned over the anvil, deformed by means of the punch of the crimping tool 50, 51 and in this way fastened to the conductor end of the cable. This position in which the crimping tool 50, 51 can perform the crimping process is called the process position.

The crimping tool replacement device 60 includes at least two replacement locations. It is also conceivable that the crimping tool replacement device 60 has three, four or more exchange places. The exchange places each serve to hold a crimping tool 50, 51. The exchange places can be exchange tables 23, 24, as shown in the figures.

The crimping tool 50, 51 is mounted on an adapter plate 80, 81 or fixed immovably. The adapter plate 80, 81 is moved together with the crimping tool 50, 51 or vice versa. By the immovable fastening of the adapter plate 80, 81 on the support plate 25, the crimping tool 50, 51 is also immovably fixed to the support plate 25. The crimping tool 50, 51 can be mounted on the adapter plate 80, 81 in different positions, since the adapter plate 80, 81 made in two parts is. The adapter plate 80, 81 comprises an adapter plate frame 83 and a receiving plate 84 arranged displaceably on it (and to be fixed with screws 150, 151, 152). The receiving plate 84 is displaceable, since the screws 150, 151, 152 are arranged in correspondingly larger through holes or slot holes the receiving plate 84 are arranged. The receiving plate 84 is connected by means of the three screws 150, 151, 152 with the adapter plate 80, 81 and the adapter plate frame 83 and attached thereto.

On the receiving plate 84 three hook-shaped elements are attached: two fixed hook-shaped elements or hooks 87, 87 'and a movable hook-shaped element or hook 88. The hooks 87, 87', 88 serve to clamp the crimping tool.

The support plate 25 has two guide rails 39 which can be aligned with the guide rails 37 of the first exchange table 23 or in alignment with the guide rails 38 of the second exchange table 24. In addition, the support plate 25 on a stop member 35. When the adapter plate 80, 81 with the crimping tool 50, 51 fastened thereon is displaced or moved in the guide rails 39 until the adapter plate 80, 81 abuts against the abutment part 35, the crimping tool 50, 51 is in the process position in FIG the crimping press 10.

The two exchange tables 23, 24 are connected rigidly to one another such that the movement of a replacement table 23, 24 simultaneously moves the other exchange table 23, 24. Each of the exchange tables 23, 24 has guide rails 37, 38 which run parallel to one another and comprise an outer edge of the adapter plate 80, 81.

The two exchange tables 23, 24 are of identical construction. The two exchange tables 23, 24 are movable by means of a movement device. For this purpose, the crimping tool replacement device 60 has a first pneumatic cylinder 45. By means of the first pneumatic cylinder 45, the two exchange tables 23, 24 in the x direction (in Fig. 3 to the right rear and to the left front) guided by two rails slidable.

In the first exchange position and the second exchange position, the exchange tables 23, 24 are each arranged such that the first crimping tool 50 and second Crimping tool 51 can be moved or moved from the process position to the first exchange table 23 or from the second exchange table 24 in the process position on the support plate 25 without height change. The support plate 25 rests on the lower tool holder 19 of the crimping press 10. The first exchange table 23 or the upper surface of the first replacement table 23 and the second replacement table 24 and the upper surface of the second exchange table 24 are mounted at the same level as the support plate 25 and the upper surface, respectively Therefore, the crimping tool 50, 51 can be moved from the process position on the platen 25 to the first replacement table 23 and the second replacement table 24 or vice versa, without raising or lowering the crimping tool 50, 51.

In Fig. 3 the exchange places are arranged in the first exchange position. The two exchange tables 23, 24 each have a recess 40, 41, which is arranged centrally between the respective two guide rails 37, 38. The support plate 25 also has a recess 42 which is arranged centrally between the guide rails 39 of the support plate 25. In the recesses 40, 41, 42, a driver 30 can be moved, which engages in a guide opening 31 of the adapter plate 80, 81. When the driver 30 is located in the guide opening 31 of the adapter plate 80, 81, the adapter plate 80, 81, and thus also the crimping tool replacement device 60 mounted on the adapter plate 80, 81, moves as the carrier 30 is moved. In the first exchange position, the recess 42 of the support plate 25 is aligned with the recess 40 of the first exchange table 23. In the second exchange position, the recess 42 of the support plate 25 is aligned with the recess 41 of the second exchange table 24 aligned. The driver 30 presses the respective adapter plate 80, 81 against a stop member 35 and thus fixes the adapter plate 80, 81 such that the crimping tool 50, 51 is in the process position.

The driver 30 can by means of a second pneumatic cylinder 46 in the y-direction (in Fig. 3 to the left rear and to the right front). In addition, the crimping tool replacement device 60 includes a third pneumatic cylinder 47, with which the driver 30 can be moved in the z-direction. The z-direction is perpendicular to the plane spanned by the x-direction and y-direction. By the movement of the third pneumatic cylinder 47, the driver 30 in the guide opening 31 of the Adapter plate 80, 81 inserted from bottom to top and removed from top to bottom again.

In the first exchange position, a part of the first replacement table 23, namely a first step-shaped projection 160, rests on the support plate 25. In the second exchange position, a part of the second exchange table 24, namely a second step-shaped projection 161, rests on the support plate 25. The support plate 25 has a step-shaped projection 162 which is complementary to the respective projections 160, 161 of the first replacement table 23 and of the second replacement table 24. The two projections 160, 161 of the two exchange tables 23, 24 are of identical construction. The support plate 25 rests on the lower tool holder.

The crimping tool replacement device 60 comprises a guide device for holding and guiding a holding pin 13 of the first crimping tool 50 and the second crimping tool 51. The guiding device comprises a guide track 12, which is substantially T-shaped. At the two opposite ends of the T-shaped guideway 12, the retaining pin 13, 13 'of the crimping tool 50, 51 are inserted or made in the guide band. At the intersection of the T-shaped guideway 12, a movable gate piece 14 is arranged. The link 14 is moved when moving the crimping tool 50, 51 to the process position in each case in the x direction and prevents a dropout of the holding pin 13, 13 'from the guideway 12 at the intersection of the guideway 12. The guideway 12 is at such height or arranged such a level (above the platen 25) that the guide track 12 is level with the recording of the upper tool holder 11 of the crimping press 10. When moving or moving the crimping tool 50, 51, the retaining pin 13, 13 'thus passes without a change in the height of the guide track 12 in the upper tool holder 11 and vice versa. The shape of the guideway 12 allows the crimping tools 50, 51 the same movements caused by the movement of the exchange tables 23, 24, the method of the first crimping tool 50 from the process position to the first exchange table 23 in the first exchange position and the method of the second crimping tool 51 from the second exchange table 24 in the second exchange position. The movements of the crimping tool 50, 51 and, consequently, of the retaining pin 13, 13 'of the crimping tool 50, 51 are performed by active movement of the cam 30 by the moving device.

The crimping tools 50, 51 each have a contact roller holder 90, 91, which feeds the crimp contacts 70 from a crimp contact roller 95, 95 '. The crimp contacts 70 and the crimp contact roller 95, 95 'are always moved together uniformly with the respective crimping tool 50, 51.

Each of the two exchange tables 23, 24 has a ball pressure piece 28, which serves for the releasable attachment of the respective crimping tool 50, 51 to the respective replacement table 23, 24. The ball pressure piece 28 engages in each case from the side in the adapter plate 80, 81 and thereby fixes them.

Fig. 6-10 FIG. 2 shows perspective views of the individual steps of replacing the first crimping tool 50 with a second crimping tool 51 by means of the crimping tool replacement device 60 Fig. 1 , In Fig. 6 is the first crimping tool 50 in the process position, ie in the position in which the crimping press 10 can connect a first crimp contact 70 by means of the crimping tool 50, 51 with a conductor end of the cable. The first crimping tool 50 is fixed on a first adapter plate 80. The adapter plate 80 is in turn pressed by the driver 30 against the stop member.

Now, a second crimping tool 51 having a second crimping contact 70, which may be different from the first crimping contact 70, is provided on the second replacement table 24. The second crimping tool 51 is arranged on a second adapter plate 81. Preferably, the second crimping tool 51 is disposed at the same position with respect to the second adapter plate 81 as the first crimping tool 50 with respect to the first adapter plate 80. The second adapter plate 81 is inserted into the guide rails 38 of the second replacement table 24.

Now, the second crimping tool 51 is shifted to the right and the movable part of the second crimping tool 51 (the upper part of the second crimping tool 51 with the holding pin 13 ') is raised to push it into the guide track 12. The second crimping tool 51 on the second adapter plate 81 is so far to the right in Fig. 6 shifted until the ball pressure piece 28, the second adapter plate 81 is fixed. Thereafter, the contact strip with the crimp contacts 70 is inserted into the second crimping tool 51.

The state after these steps is in Fig. 7 shown.

Now the replacement process is triggered by the movement device is activated. The driver 30 moves from the (in Fig. 7 rightmost) position in which the driver 30 presses the first holding plate against the stop member 35, to the left (ie away from the stop member 35) and pushes or moves so that the first adapter plate 80 with the first crimping tool 50 from the platen 25 on the first interchange table 23. The driver 30 moves as far as possible to the left in Fig. 7 , This happens until the ball pressure piece 28 of the first replacement table 23 fixes the first adapter plate 80 and thus the first crimping tool 50 on the first replacement table 23.

The state after this step or steps is in Fig. 8 shown.

Now the driver 30 moves down. As a result, the driver 30 comes out of the guide opening 31 of the first adapter plate 80th

Thereafter, the replacement tables 23, 24, i. the exchange places, moved backwards in x-direction. This happens until the guide rails 38 of the second exchange table 24 are aligned with the guide rails 39 of the support plate 25. Now, the second exchange table 24 is located with the second crimping tool 51 at the point at which the first exchange table 23 with the first crimping tool 50 was previously located. The gate in the guide track 12 is pushed by the retaining pin 13 'of the second crimping tool 51 to the rear. The guide pin of the second crimping tool 51 is now located at the intersection of the guide track 12.

The state after this step is in Fig. 9 shown.

Now the driver 30 moves up again and is inserted into the guide opening 31 of the second adapter plate 81, on which the second crimping tool 51 is fixed. Subsequently, the driver 30 moves to the right and moves the second crimping tool 51 along the guide rails 38, 39 from the second exchange table 24 to the support plate 25 (in the y-direction). The driver 30 moves so far to the right and moves the second adapter plate 81 with the second crimping tool 51 to the second adapter plate 81 presses against the stop member 35. Now, the second crimping tool 51 is in the process position. In the process, the holding pin 13 'of the second crimping tool 51 passes into the upper tool holder 11 of the crimping press 10.

The state (final state) after this step is in Fig. 10 shown.

Now, the first crimping tool 50 can remain on the first replacement table 23 or be removed from the first replacement table 23 (after the solution of the first locking device). Subsequently, another crimping tool can be placed on the first exchange table 23. Now, the replacement process can be performed again. Here, the second crimping tool 51 is again moved to the second receiving table, the exchange tables 23, 24 moved forward and then moved the first crimping tool 50 from the first exchange table 23 on the support plate 25 in the process position.

It is also conceivable that of the in Fig. 10 shown state, the second crimping tool 51 is removed from the second exchange table 24 and the exchange tables 23, 24 are moved forward.
