[0034] In the design process of the bending piece 4, the actual position and size of the through hole 421 on the bending piece 4 are set according to requirements, wherein the designed position of the through hole 421 on the bending piece 4 is a punching position, in the design process, the punching position of the bending piece 4 is corresponded to the die hole 221 of the lower die seat 2, the bending piece 4 sets at least two positioning holes 411 according to the die hole 221 and the punching position, the set positioning holes 411 can all find corresponding positioning pins 13 on the positioning area 12, and it is ensured that the positioning pins 13 can pass through the positioning holes 411; in the processing process, the positioning pins 13 corresponding to the positioning holes 411 are first installed in the positioning area 12, the bending piece 4 is positioned through the cooperation of the positioning pins 13 and the positioning holes 411, so that the punching position on the bending piece 4 corresponds to the die hole 221, then the driving device 33 controls the punching piece 35 to descend and act on the bending piece 4, thereby forming the through hole 421 on the punching position of the bending piece 4.

[0035] The bending piece 4 is positioned by the cooperation of the positioning pin 13 and the positioning hole 411 in the embodiment, so that the position to be punched of the bending piece 4 is aligned with the die hole 221 of the lower die seat 2, the actual formed through hole 421 of the bending piece 4 by the punching piece 35 is consistent with the designed position and size of the through hole 421, and the precision of the position and size of the through hole 421 can be significantly improved; in addition, there are a plurality of positioning pins 13 in the positioning area 12, and the corresponding positioning pin 13 can be selected according to the shape and specification of the bending piece 4, so that the punching device can position a plurality of bending pieces 4 of different specifications, and the punching device can also punch the accurate through hole 421 for the bending pieces 4 of different specifications, so that the position and size of the through hole 421 of the same batch of bending pieces 4 of different specifications can be highly unified, the error caused by human factors is reduced, and the qualified rate of the bending piece 4 is higher; secondly, the punching device can be suitable for a plurality of bending pieces 4 of different specifications, and one punching device can punch a plurality of bending pieces 4 of different specifications, so that the processing cost of the bending piece 4 can be reduced, and the positioning difficulty of the bending piece 4 can be reduced by only replacing the positioning pin 13 at different positions, which helps to improve the processing efficiency of the bending piece 4.

[0036] Specifically, as shown in Figure 2 the positioning area 12 in the embodiment is a rectangular structure, a plurality of insertion grooves 121 are arranged in the positioning area 12, the positioning pin 13 and the insertion groove 121 are detachably connected by insertion, and after the positioning pin 13 is inserted into the insertion groove 121, the positioning pin 13 is vertically placed. The connection mode of insertion makes the installation and disassembly process of the positioning pin 13 extremely simple and fast, and the operator does not need to use complex tools or perform tedious operations.
