[0029] See Figures 1 to 5 , a conductive contact composite forming device according to an embodiment of the present utility model, comprising: a punching die 100, a bending mechanism 200, and a conveying mechanism. The punching die 100 includes a lower die assembly 110 and an upper die assembly 120 that moves up and down relative to the lower die assembly 110. The lower die assembly 110 is used to carry a long strip of material 10. The conveying mechanism is used to drive one end of the long strip of material 10 to extend out of the output end of the punching die 100. The bending mechanism 200 is disposed at the output end of the punching die 100. When the upper die assembly 120 presses down on the lower die assembly 110 to cut a portion of the long strip of material 10 near the output end of the punching die 100 according to a certain length dimension to form a strip-shaped sheet 20, the bending mechanism 200 can bend the free end of the strip-shaped sheet 20 extending out of the punching die 100 into a preset shape to form a conductive contact.

[0030] The conductive contact composite forming device with the above structure uses the upper die assembly 120 and the lower die assembly 110 of the punching die 100 to punch a strip-shaped sheet 20 for forming a conductive contact on the long strip material 10 when the upper die assembly 120 and the lower die assembly 110 are closed. While the upper die assembly 120 and the lower die assembly 110 clamp the strip-shaped sheet 20, the bending mechanism 200 bends the part of the strip-shaped sheet 20 extending out of the punching die 100 into a preset shape, so that the punching and bending forming processes are both formed under the same positioning reference, thus ensuring the processing accuracy of the conductive contact. Moreover, the structure of the conductive contact composite forming device is simple, the cost is low, the material utilization rate is high when manufacturing the conductive contact, and a large amount of material waste is avoided. It should be noted that the conveying mechanism is used to intermittently drive the long strip material 10 to feed and move a certain distance in the direction of the bending mechanism 200. The distance of a single movement of the long strip material 10 is the length dimension of a strip-shaped sheet 20. When the upper die assembly 120 moves away from the lower die assembly 110, the formed conductive contact can leave the bending mechanism 200 under the action of the conveying mechanism or an external manipulator or its own gravity.

[0031] See Figure 1 , in some embodiments of the present invention, the bending mechanism 200 includes a downward pressing component 210 and a side pressing component 220. The downward pressing component 210 is used to bend the strip-shaped sheet 20 downward to form a corner part, and the side pressing component 220 is used to bend the free end of the strip-shaped sheet 20 into a preset shape. The downward pressing component 210 is connected to the side pressing component 220 through a first linkage mechanism 300 so that the downward pressing component 210 and the side pressing component 220 act in sequence. It can be understood that after the downward pressing component 210 moves downward to form a corner part on the strip-shaped sheet 20, the first linkage mechanism 300 is used to drive the side pressing component 220 to act to bend the free end of the strip-shaped sheet 20 into a preset shape, ensuring that the downward pressing component 210 and the side pressing component 220 produce continuous actions, which not only meets the manufacturing requirements of the conductive contact, but also ensures that the corner part and the end of the conductive contact are both formed under the same positioning reference, thus guaranteeing the processing accuracy.

[0032] See Figure 2 and Figure 5, in some embodiments of the present utility model, the downward pressing assembly 210 includes a supporting member 211 and a longitudinal slider 212 movably disposed above the supporting member 211. The supporting member 211 has a supporting plane 2111 for supporting the strip-shaped sheet 20 and a forming side surface 2112 for forming the shapes of the corner portion and the end portion of the conductive contact piece. The longitudinal slider 212 is provided with a corner forming member 213 protruding from its lower end. The side pressing assembly 220 includes a transverse slider 221. A side bending member 222 located below the corner forming member 213 protrudes from the side wall of the transverse slider 221 close to the supporting member 211. The first linkage mechanism 300 includes a downward pressing driving member 310. The downward pressing driving member 310 is connected to the longitudinal slider 212 through a longitudinally arranged first elastic member 320 to drive the longitudinal slider 212 to move downward. A first inclined surface 330 inclined upward from bottom to top towards the longitudinal slider 212 is provided on the side of the transverse slider 221 away from the side bending member 222. The downward pressing driving member 310 is connected with a lifting block 340 extending downward. A second inclined surface 350 matching the first inclined surface 330 is provided at the lower end of the lifting block 340. It should be noted that referring to Figures 2 to 4 , when the downward pressing driving member 310, the first elastic member 320 and the longitudinal slider 212 move downward together, the longitudinal slider 212 abuts downward against the supporting plane 2111, and the corner forming member 213 bends the strip-shaped sheet 20 to form a corner portion. As the downward pressing driving member 310 continues to move downward, the first elastic member 320 is compressed, and the longitudinal slider 212 remains in contact with the supporting plane 2111. The lifting block 340 follows the downward pressing driving member 310 to descend until the second inclined surface 350 contacts the first inclined surface 330 of the transverse slider 221. As the second inclined surface 350 moves vertically downward, the transverse slider 221 is pushed until the side bending member 222 abuts against the free end of the strip-shaped sheet 20 and bends to form a preset shape. The structures of the downward pressing assembly 210, the bending mechanism 200 and the first linkage mechanism 300 with the above structure are very simple, and the successive actions of the downward pressing assembly 210 and the side pressing assembly 220 are realized in a simple structure and action mode, which not only meets the manufacturing requirements of the conductive contact piece, but also ensures that the corner portion and the end portion of the conductive contact piece are formed under the same positioning reference, thereby ensuring the processing accuracy.

[0033] Referring to Figure 1 and Figure 5In some embodiments of the utility model, the bending mechanism 200 further comprises a mounting seat 400 arranged at the output end of the punching die 100, the down-pressing assembly 210 and the side-pressing assembly 220 are both arranged on the mounting seat 400, the side of the transverse slider 221 away from the side bending component 222 is connected with a horizontally extending rod 500, the mounting seat 400 is provided with a stop guide block 410 opposite to the side of the transverse slider 221 away from the side bending component 222, the end of the rod 500 is movably inserted into the stop guide block 410, and the end of the rod 500 is in contact with the stop A return spring 510 is provided between the moving guide block 410 to drive the transverse slider 221 to slide against the stop guide block 410. A clearance groove 341 with a downward opening for the rod 500 to pass through is horizontally penetrated through the lower part of the lifting block 340. The lifting block 340 can move downward along the side wall of the stop guide block 410 close to the transverse slider 221, so as to push the side bending component 222 to move close to the supporting component 211 through the cooperation of the second inclined surface 350 and the first inclined surface 330, and make the rod 500 enter the clearance groove 341. In this embodiment, the lifting block 340 is roughly in the shape of a vertically arranged quadrangular prism, and the second inclined surface 350 is inclined upward from the lower end surface of the lifting block 340. It can be understood that, see Figure 1 When the punching die 100 is opened, the transverse slider 221 moves to abut against the side wall of the stop guide block 410 under the action of the return spring 510. At this time, the lifting block 340 is located directly above the transverse slider 221 so that the second inclined surface 350 and the first inclined surface 330 are arranged opposite to each other. The side wall of the lifting block 340 away from the supporting member 211 abuts against the side wall of the stop guide block 410 close to the transverse slider 221, so that the stop guide block 410 plays a role in guiding the lifting and lowering movement of the lifting block 340. Figure 2 or Figure 3 During the closing process of the punching die 100, the lifting block 340 follows the pressing driving member 310 to descend until the second inclined surface 350 contacts the first inclined surface 330 of the horizontal slider 221. As the second inclined surface 350 moves vertically downward, the horizontal slider 221 slides toward the supporting member 211 to move away from the stop guide block 410, see Figure 4 , until the lifting block 340 separates the lateral slider 221 from the stop guide block 410, under the action of the return spring 510, the lateral slider 221 and the stop guide block 410 clamp the lifting block 340 to stabilize the side bending component 222 against the position of the strip sheet 20, during which the rod 500 enters the clearance groove 341 from the lower opening of the clearance groove 341, and the rod 500 moves laterally relative to the stop guide block 410 and the clearance groove 341 toward the supporting member 211, thereby compressing the return spring 510. Figure 1When the upper mold assembly 120 moves upward away from the lower mold assembly 110, the lifting block 340 moves upward, and under the action of the return spring 510, the first inclined surface 330 abuts against the second inclined surface 350. When the second inclined surface 350 is completely separated from the first inclined surface 330, the transverse slider 221 abuts against the side wall of the stop guide block 410. Generally speaking, since the side of the transverse slider 221 close to the supporting member 211 is used to set the side bending component 222, and the side of the transverse slider 221 opposite to the side bending component 222 is supported by the lifting block 340, resulting in a place for the return spring 510 that drives the transverse slider 221 to return to its original position. The above technical solution cleverly solves this problem.

[0034] See also Figure 4 and Figure 5 , wherein the mounting seat 400 is provided with a sliding hole extending along the width direction of the strip sheet 20, the supporting member 211 is telescopically movable along the sliding hole, the supporting member 211 is connected to a cylinder, the cylinder drives the supporting member 211 to extend to the bottom of the strip sheet 20 to support the strip sheet 20, when the bending mechanism 200 completes the work, the longitudinal slider 212 moves away from the supporting member 211 upward, and the transverse slider 221 moves away from the supporting member 211 from the side, at this time, the cylinder drives the supporting member 211 to retract so that the formed conductive contact sheet can fall. Specifically, the length dimension of the portion of the strip sheet 20 extending from the punching die 100 is greater than the portion of the strip sheet 20 located on the punching die 100, so when the strip sheet 20 is cut, the formed conductive contact sheet can fall under its own gravity, and there is no need to set up an external manipulator to unload the conductive contact sheet, which is conducive to further simplifying the structure of the conductive contact sheet composite molding device and reducing costs. In other embodiments, the cylinder can also be replaced by other linear actuators such as electric push rods. The electric push rods and the conveying mechanism are both connected to the control module. Before the conveying mechanism conveys the long strip 10 to the direction of the bending mechanism 200 by a distance of a strip sheet 20, the control module controls the electric push rods to extend the supporting member 211. In this embodiment, the supporting member 211 is columnar, and the mounting seat 400 includes a vertically placed plate. The sliding hole is set through the plate and is consistent with the cross-sectional shape of the supporting member 211. The sliding hole is used to guide the telescopic movement of the supporting member 211.

[0035] See also Figure 5, in some embodiments of the present utility model, the longitudinal slider 212 is connected with a pressing block 215 that can elastically extend out of the lower end of the longitudinal slider 212 through a second elastic member 214. The pressing block 215 presses the strip-shaped sheet 20 against the supporting plane 2111. A first limiting groove 216 is formed by the downward depression of the lower end surface of the longitudinal slider 212. The pressing block 215 can compress the second elastic member 214 to completely enter the first limiting groove 216. It should be noted that since the corner forming member 213 protrudes from the lower end of the longitudinal slider 212, during the process of the longitudinal slider 212 moving downward to contact the strip-shaped sheet 20, the corner forming member 213 first contacts the strip-shaped sheet 20, resulting in the part of the strip-shaped sheet 20 corresponding to the supporting plane 2111 not being positioned. At this time, the part of the strip-shaped sheet 20 facing the supporting plane 2111 is prone to irregular deformation, causing manufacturing deviation in the corner part of the strip-shaped sheet 20. In the above structure, the pressing block 215 extends downward below the corner forming member 213 under the action of the second elastic member 214. During the process of the longitudinal slider 212 moving downward, the pressing block 215 first contacts the supporting plane 2111 of the supporting member 211, thereby clamping the strip-shaped sheet 20, and then the corner forming member 213 contacts the strip-shaped sheet 20. During this process, the pressing block 215 can compress the second elastic member 214 to enter the first limiting groove 216. When the corner forming member 213 bends the strip-shaped sheet 20 to form a corner part, the lower end surface of the pressing block 215 is flush with the lower end surface of the longitudinal slider 212.

[0036] See Figure 5 , in some embodiments of the present utility model, in order to ensure the shape accuracy of the end of the conductive contact piece, the side bending member 222 includes a first top block 223 and a second top block 224 that are arranged at intervals up and down on the transverse slider 221. The first top block 223 corresponds to the strip-shaped sheet 20 near the corner part, and the second top block 224 corresponds to the free end of the strip-shaped sheet 20. The first top block 223 is connected to the transverse slider 221 through a third elastic member 225. The third elastic member 225 can drive the first top block 223 to extend out of the end of the second top block 224. That is, during the process of the transverse slider 221 moving close to the supporting member 211, the first top block 223 first contacts the part of the strip-shaped sheet 20 near the corner part, playing a positioning role. Then, after the first top block 223 moves a certain distance in the direction of compressing the third elastic member 225, the second top block 224 contacts the end of the strip-shaped sheet 20, thereby bending the end of the strip-shaped sheet 20 into a preset shape, and then obtaining a conductive contact piece with higher shape accuracy.

[0037] See Figure 5In some embodiments of the utility model, the transverse slider 221 is provided with an active channel penetrating the side wall of the transverse slider 221 near the longitudinal slider 212, the first top block 223 is slidably arranged in the active channel, the side of the first top block 223 is provided with a limiting protrusion 226, the active channel is provided with a second limiting groove 227 matched with the limiting protrusion 226 to limit the sliding stroke of the first top block 223, and the third elastic member 225 is located in the active channel to drive the end of the first top block 223 to contact the strip sheet 20 before the end of the second top block 224. The second limiting groove 227 and the limiting protrusion 226 cooperate to limit the longest distance and the shortest distance of the first top block 223 extending relative to the transverse slider 221. When the first top block 223 is at the shortest distance extending from the transverse slider 221, the first top block 223 can rigidly press the position of the strip sheet 20 near the corner onto the supporting member 211.

[0038] See also Figure 3 or Figure 4 In some embodiments of the utility model, the longitudinal slider 212 includes a first block and a first cover, the first block is provided with a first mounting groove for mounting the side opening of the corner molding 213, and the first cover is detachably connected to the first block to close the side opening of the first mounting groove; the transverse slider 221 includes a second block and a second cover, the second block is provided with a second mounting groove for mounting the side opening of the side bending component 222, and the second cover is detachably connected to the second block to close the side opening of the second mounting groove. It is understandable that when the specifications of the produced conductive contact sheet change, the user can remove the first cover and the second cover, and then adjust the production and processing by replacing the corner molding 213 and the side bending component 222.

[0039] See also Figure 1 , Figure 2 In some embodiments of the present invention, the upper die seat of the upper die assembly 120 has an overhanging plate portion extending horizontally toward the bending mechanism 200, and the overhanging plate portion constitutes the down-pressing driving member 310. It can be understood that while the upper die seat moves downward to achieve the mold closing of the upper die assembly 120 and the lower die assembly 110, the down-pressing driving member 310 also moves downward synchronously to drive the down-pressing assembly 210 and the side-pressing assembly 220 to work successively, which not only eliminates the action delay problem between the punching die 100 and the bending mechanism 200, ensures that the strip sheet 20 is bent while being punched, but also does not need to be additionally configured with a driving source to drive the down-pressing driving member 310 to move up and down, which ingeniously simplifies the structure, reduces costs, and can obtain better processing accuracy.

[0040] See also Figure 1, in some embodiments of the present utility model, a plurality of side limiting members 130 for limiting the two side edges of the long strip material 10 are arranged at intervals along the conveying direction of the long strip material 10 on the lower die assembly 110, and a plurality of punching assemblies 140, trimming assemblies 150 and cutting assemblies 160 are arranged between the lower die assembly 110 and the upper die assembly 120. In this embodiment, a plurality of side limiting members 130 arranged at intervals along the conveying direction of the long strip material 10 are respectively configured on both sides of the long strip material 10 on the lower die assembly 110. The conveying mechanism pushes the long strip material 10 to move towards the bending mechanism 200. The punching assembly 140 can form the positioning holes required for the conductive contact on the long strip material 10, and the trimming assembly 150 can remove part of the material from the side edge of the long strip material 10 to obtain a strip-shaped sheet 20 with a corresponding shape, so as to supply the bending mechanism 200 for bending to obtain the conductive contact. Of course, in other embodiments, the composition of the cutting die can be adjusted accordingly, and the corresponding functional components can be increased or decreased.
