It should be noted that, referring to fig. 2 to 4, when the push-down driving member 310, the first elastic member 320 and the longitudinal slider 212 move downward together, the longitudinal slider 212 pushes down against the supporting plane 2111, the corner forming member 213 bends the strip-shaped sheet 20 to form a corner portion, as the push-down driving member 310 continues to move downward, the first elastic member 320 is compressed, the longitudinal slider 212 keeps contacting the supporting plane 2111, the lifting block 340 descends along with the push-down driving member 310 until the second inclined surface 350 contacts the first inclined surface 330 of the lateral slider 221, and as the second inclined surface 350 moves vertically downward, the lateral slider 221 is pushed to push the lateral bending member 222 against the free end of the strip-shaped sheet 20 to bend into a preset shape. The pressing assembly 210, the bending mechanism 200 and the first linkage mechanism 300 with the above structure are very simple in structure, and the pressing assembly 210 and the side pressing assembly 220 are sequentially operated in a simple structure and an operation mode, so that the manufacturing requirement of the conductive contact is met, the corner part and the end part of the conductive contact are ensured to be molded under the same positioning reference, and the machining precision is ensured.
Referring to fig. 1 and 5, in some embodiments of the present invention, the bending mechanism 200 further includes a mounting seat 400 provided at an output end of the punching die 100, the pressing assembly 210 and the side pressing assembly 220 are both provided at the mounting seat 400, a rod 500 horizontally extending is connected to a side of the lateral slider 221 away from the lateral bending member 222, the mounting seat 400 is provided with a stop guide block 410 opposite to a side of the lateral slider 221 away from the lateral bending member 222, an end portion of the rod 500 movably penetrates the stop guide block 410, a return spring 510 for driving the lateral slider 221 to slide against the stop guide block 410 is provided between the end portion of the rod 500 and the stop guide block 410, a relief groove 341 for allowing the rod 500 to pass through is horizontally provided at a lower portion of the lifting block 340, and the lifting block 340 can move downward along a side wall of the stop guide block 410 close to the lateral slider 221 so as to support the lateral slider 221 by the second inclined surface 350 and the first inclined surface 350 to push the first inclined surface 330 to move the lateral bending member 222 close to the lateral bending member 211, and causing the lever 500 to enter the relief groove 341. In the present embodiment, the lifting block 340 has a substantially vertically disposed quadrangular prism shape, and the second inclined surface 350 is disposed obliquely upward from the lower end surface of the lifting block 340. As can be appreciated, referring to fig. 1, when the punching die 100 is opened, the lateral slider 221 moves to abut against the side wall of the stop guide block 410 under the action of the return spring 510, and the lifting block 340 is located directly above the lateral slider 221 so that the second inclined surface 350 and the first inclined surface 330 are disposed opposite to each other, and 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 adjacent to the lateral slider 221, so that the lifting movement of the lifting block 340 is guided by the stop guide block 410. Referring to fig. 2 or 3, in the process of closing the punching die 100, the lifting block 340 descends following the pressing-down driving member 310 until the second inclined surface 350 contacts the first inclined surface 330 of the lateral slider 221, the lateral slider 221 slides in a direction toward the holder 211 to be away from the stopper guide block 410 as the second inclined surface 350 moves vertically downward, see fig. 4, until the lifting block 340 separates the lateral slider 221 from the stopper guide block 410, the lateral slider 221 and the stopper guide block 410 form a clamping effect on the lifting block 340 by the return spring 510 to stabilize a position of the lateral bending member 222 against the strip sheet 20, in which the rod 500 enters the relief groove 341 from a lower opening of the relief groove 341, and the rod 500 moves in a direction toward the holder 211 relative to the stopper guide block 410 and the relief groove 341, thereby compressing the return spring 510. Referring to fig. 1, when the upper die assembly 120 is upwardly far from the lower die assembly 110, the lifting block 340 is upwardly moved, the first inclined surface 330 is abutted against the second inclined surface 350 by the return spring 510, and when the second inclined surface 350 is completely separated from the first inclined surface 330, the lateral slider 221 is abutted against the sidewall of the stopper guide block 410. In general, since the side of the lateral sliding block 221 near the supporting member 211 is used for setting the lateral bending member 222, and the opposite side of the lateral sliding block 221 and the lateral bending member 222 is supported by the lifting block 340, the restoring spring 510 for driving the lateral sliding block 221 to restore is not available, and the above technical solution skillfully solves the problem.
Referring to fig. 4 and 5, the mounting base 400 is provided with a sliding hole extending along the width direction of the strip-shaped sheet 20, the supporting member 211 moves telescopically along the sliding hole, the supporting member 211 is connected with an air cylinder, the air cylinder drives the supporting member 211 to extend below the strip-shaped sheet 20 to support the strip-shaped sheet 20, after the bending mechanism 200 finishes working, the longitudinal sliding block 212 is upwards far away from the supporting member 211, the transverse sliding block 221 is laterally far away from the supporting member 211, and at the moment, the air cylinder drives the supporting member 211 to retract so that the formed conductive contact piece can fall. Specifically, the length dimension of the portion of the strip-shaped sheet 20 extending out of the punching die 100 is greater than the portion of the strip-shaped sheet 20 located on the punching die 100, so that after the strip-shaped sheet 20 is cut, the formed conductive contact can fall under the action of self gravity, no external manipulator is needed to be arranged for unloading the conductive contact, and the structure of the conductive contact composite forming device is further simplified, and the cost is reduced. In other embodiments, the cylinder may be replaced by another linear driver such as an electric push rod, where the electric push rod and the conveying mechanism are connected to the control module, and the control module controls the electric push rod to extend the supporting member 211 before the conveying mechanism conveys the strip 10 to the direction of the bending mechanism 200 by a distance of one strip 20. In this embodiment, the supporting member 211 is columnar, the mounting base 400 includes a plate member placed vertically, the sliding hole penetrates through the plate member and is consistent with the cross-sectional shape of the supporting member 211, and the sliding hole is used for guiding the supporting member 211 to move in a telescopic manner.

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 moving the longitudinal slider 212 downward to contact the strip-shaped sheet 20, the corner forming member 213 contacts the strip-shaped sheet 20 first, so that the portion of the strip-shaped sheet 20 corresponding to the support plane 2111 is not positioned, and at this time, an irregular deformation is easily generated at the portion of the strip-shaped sheet 20 facing the support plane 2111, so that a manufacturing deviation occurs at the corner portion 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, and in the process of moving the longitudinal slider 212 downward, the pressing block 215 contacts the bearing plane 2111 of the bearing member 211 to clamp the strip-shaped sheet 20, and then the corner forming member 213 contacts the strip-shaped sheet 20, in this process, the pressing block 215 can compress the second elastic member 214 to enter the first limiting groove 216, and when the corner forming member 213 bends the strip-shaped sheet 20 to form a corner portion, the lower end face of the pressing block 215 is flush with the lower end face of the longitudinal slider 212.

Referring to fig. 5, in some embodiments of the present invention, a movable channel penetrating through the lateral slider 221 and close to the side wall of the longitudinal slider 212 is provided in the lateral slider 221, the first top block 223 is slidably disposed in the movable channel, a limit protrusion 226 is disposed on a side portion of the first top block 223, the movable channel is provided with a second limit groove 227 matched with the limit protrusion 226 to limit the sliding travel of the first top block 223, and the third elastic member 225 is located in the movable channel to drive the end portion of the first top block 223 to contact the strip-shaped sheet 20 earlier than the end portion of the second top block 224.

It will be appreciated that when the specifications of the conductive contacts produced change, the user can remove the first and second covers and then adjust the production process by replacing the corner molding 213 and the side bend 222.
Referring to fig. 1 and 2, in some embodiments of the present invention, the upper die base of the upper die assembly 120 has an overhanging plate portion extending horizontally toward the bending mechanism 200, the overhanging plate portion constituting the push-down driver 310. It can be appreciated that, when the upper die holder moves downward to achieve the die assembly of the upper die assembly 120 and the lower die assembly 110, the pressing driving member 310 also moves downward synchronously to drive the pressing assembly 210 and the side pressing assembly 220 to work sequentially, which not only eliminates the problem of action delay 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 provided with a driving source for driving the pressing driving member 310 to move up and down, thereby skillfully simplifying the structure, reducing the cost and obtaining better processing precision.
Referring to fig. 1, in some embodiments of the present invention, a plurality of side limiting members 130 for limiting both side edges of the strip 10 are disposed at intervals along the conveying direction of the strip 10 in the lower die assembly 110, and a plurality of punching assemblies 140, trimming assemblies 150 and cutting assemblies 160 are disposed between the lower die assembly 110 and the upper die assembly 120. In this embodiment, the lower die assembly 110 is respectively configured with a plurality of side limiting members 130 disposed at intervals along the conveying direction of the strip 10 on both sides of the strip 10, the conveying mechanism pushes the strip 10 to move toward the bending mechanism 200, the punching assembly 140 can form positioning holes required by the conductive contacts on the strip 10, and the trimming assembly 150 can remove part of the material on the side edges of the strip 10 to obtain the strip 20 with a corresponding shape, so as to supply the bending mechanism 200 to bend to obtain the conductive contacts. Of course, in other embodiments, the components of the slave cutting die may also be adjusted accordingly, and the corresponding functional components may be added or subtracted.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
