[0033] The central axis of the bending hole 33, the central axis of the pressing member 82 and the central axis of the material receiving column 313 are all coincident with each other to ensure the consistency of product quality during bending.

[0034] Each of the support frames 20 is fixed to the base 10 by a fastener. The fastener may be a fastening screw or a fastening bolt. In other feasible embodiments, the support frame 20 may be fixed to the base 10 by welding.

[0035] The base 10 is provided with foot pads 90 arranged at the four corners of the bottom surface of the base 10. The foot pads 90 are made of elastic material and are glued and fixed to the four corners of the bottom surface of the base 10. The setting of the foot pads 90 can effectively absorb the impact during the bending process.

[0036] When bending the conductive sheet pin, first place the conductive sheet 200 on the receiving column 313 of the conductive sheet support assembly 31, and make the positioning hole set on the conductive sheet 200 fit on the positioning column 314; then operate the operating rod 41 of the driving assembly to move from the initial position to one side of the conductive sheet support assembly 31, thereby forcing the holding block 43 to rotate with the rotating shaft 51 as the rotating axis. Since the holding edge is in an arc shape, a height difference change is formed during the rotation process, thereby driving the bending member 30 and the pressing-resetting assembly 80 installed on the bending member 30 to move relative to one side of the conductive sheet support assembly 31, until Until the positioning column 314 is nested in the groove 821 and then presses the conductive sheet 200, as the upper pressure plate 32 continues to move downward, the bending surface 34 is forced to apply a bending force to the pins of the conductive sheet 200 and bend them. During the bending process, the reset elastic member and the supporting elastic member are both in a compressed state; after the bending is completed, the operating rod 41 is released, and under the action of the supporting elastic member, the operating rod 41 returns to its initial position, and under the action of the reset elastic member, the clamping member 82 is reset downward to its initial position relative to the upper pressure plate 32. After the bent conductive sheet is taken out, the bending operation of the pins of the entire conductive sheet is completed.

[0037] See also Figure 5A conductive sheet 200 according to the second embodiment of the present invention has a sheet-shaped substrate 201 and two or more pins 202 extending integrally with the substrate and arranged around the substrate 201, and the substrate is further provided with positioning holes 203 that match the shape of the positioning column. The pins 203 of the conductive sheet 200 are bent by the conductive sheet pin bending tool 100 described in one embodiment of the present invention.

[0038] It should be noted that Figure 5 Only a circular conductive sheet is illustrated as the substrate. In other feasible embodiments, the conductive sheet can be bent such as to have an overall contour of a triangle, an ellipse, etc. Correspondingly, the bending hole 33, the clamping member 82, the receiving column 313, and the positioning column 314 are also correspondingly replaced.

[0039] In a specific embodiment, the shapes of the bending hole, the pressing member and the material receiving column are determined according to the shapes of the substrate of the conductive sheet and the positioning hole of the conductive sheet.

[0040] In summary, the utility model provides a conductive sheet pin bending tool and a conductive sheet thereof, which have the characteristics of simple and reasonable structure and easy use. The conductive sheet pins of integrated circuit boards of different shapes can be quickly bent. The fixed pins of the bent conductive sheet can be effectively matched and quickly assembled with the integrated circuit board, thereby improving product production efficiency.
