However, the existing stamping die can only form one of them, the production type is single, and the production efficiency is low. Utility Model Content

[0004] In view of the above problems in the prior art, the utility model provides a stamping die for a wire pressing plate, which solves the problem that the existing wire pressing plate stamping die can only form one wire pressing plate, resulting in a single production type and low production efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A stamping die for a wire pressing plate is provided, comprising an upper die base and a lower die base, wherein the upper die base and the lower die base are respectively arranged at the upper end and the lower end of an outer guide column assembly; an upper stripping plate is arranged on the bottom of the upper die base, a lower die plate is arranged on the top of the lower die base, and three groups of material guide plates are arranged on the lower die plate at intervals, and an arched wire pressing plate channel and a straight wire pressing plate channel are respectively formed between two adjacent groups of material guide plates, and the arched wire pressing plate channel and the straight wire pressing plate channel serve as conveying channels for a first plate and a second plate, respectively; an arched stamping assembly for stamping the arched wire pressing plate and a straight stamping assembly for stamping the straight wire pressing plate are arranged between the upper stripping plate and the lower die plate, and the arched stamping assembly and the straight stamping assembly are respectively located at the arched wire pressing plate channel and the straight wire pressing plate channel.

[0007] In this solution, the first sheet and the second sheet are placed in the arched wire pressing plate channel and the straight wire pressing plate channel respectively. The first sheet and the second sheet can be punched into an arched wire pressing plate and a straight wire pressing plate respectively through the arched stamping assembly and the straight stamping assembly. Compared with the existing method that can only produce arched wire pressing plates or straight wire pressing plates, this solution has higher production efficiency.

[0008] Furthermore, the arched stamping assembly includes a first punching block, an outer shape cutting block, an arched forming assembly and an arched shaping assembly, a second punching block and an inner shape cutting block, which are sequentially distributed along the axial direction of the arched wire pressing plate channel; the first punching block is fixed on the upper stripping plate, and is used to punch out a first positioning hole and a transition hole on both sides of the first plate, respectively, and the first positioning hole and the transition hole are convenient for positioning. The outer shape cutting block is fixed on the upper stripping plate, and is used to separate two adjacent first positioning hole positions on the first plate to process the wire pressing plate semi-finished product. The arched forming assembly is used to extrude the middle part of the wire pressing plate semi-finished product into an arch, and the arched shaping assembly is used to shape the arch on the wire pressing plate semi-finished product; the second punching block is fixed on the upper stripping plate, and is used to press the transition hole into a second positioning hole; the inner shape cutting block is fixed on the upper supporting plate, and is used to cut the wire pressing plate semi-finished product from the first plate to form an arched wire pressing plate.

[0009] Furthermore, a first punch and a second punch are symmetrically arranged on the bottom surface of the first punching block for punching and forming the first positioning hole and the transition hole, respectively, and the diameter of the first punch is larger than the diameter of the second punch.
