A positioning plate for horizontal movement of the flat copper wire during drilling; the positioning plate has a groove for restricting the horizontal movement of the flat copper wire, and the groove has a punched through hole; the punched through hole is coaxially arranged with the guide hole; secondary guide posts are respectively arranged around the positioning plate, and the lower ends of the secondary guide posts are fixed to the secondary guide post positioning plate; the secondary guide posts pass through the unloading plate and extend out of the upper template; a rear buffer sleeve is fitted on the secondary guide post; the buffer sleeve elastically supports the unloading plate and the upper template; the secondary guide post and the buffer sleeve constitute a secondary positioning and guiding mechanism; an unloading bolt is arranged between the upper template and the unloading plate; and a rectangular spring is fitted on the unloading bolt; one end of the unloading bolt is threaded to the unloading plate, and the other end is slidably engaged with the upper template; the unloading bolt and the rectangular spring constitute a tertiary positioning and guiding mechanism.

[0010] Both the lower template and the secondary guide post positioning plate have through holes coaxially arranged with the punching through holes.

[0011] The punching die proposed in this utility model adopts the above-mentioned technical solution, which solves the problem of inaccurate positioning through multi-level positioning. After the wire is punched, there is an unloading device to unload it, resulting in high work efficiency. Attached Figure Description

[0014] The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

[0015] like Figure 1 , Figure 2 As shown, a punching die has an upper template 7 and a lower template 11; a stripper plate 4 is also provided between the upper template 7 and the lower template 11; a punch 16 is provided between the upper template 7 and the stripper plate 11; the upper end of the punch 16 is fixed to the upper template 7 by a punch fixing seat 18, and the stripper plate 4 has a guide hole 17 for the punch to pass through; the punching die is also provided with a guiding and positioning mechanism to ensure the accuracy of the die movement; the guiding and positioning mechanism has multiple primary guide pillars 2; the primary guide pillars 2 pass through the upper template 7 and the stripper plate 4 and are fixed to a primary guide pillar fixing plate 1 located on the lower template; a stripper return spring 9 is sleeved on the primary guide pillar, and the stripper return spring 9 is located between the stripper plate 4 and the lower template 11; the primary guide pillars, the stripper return spring, and the cooperating bushing constitute a primary positioning and guiding mechanism; a secondary guide pillar positioning plate 3 is fixed in the middle of the primary guide pillar fixing plate 1; a punching device is placed in the middle of the secondary guide pillar positioning plate 3 to prevent punching A positioning plate 13 is provided for horizontal movement of the flat copper wire during punching. The positioning plate 13 has a groove for restricting the horizontal movement of the flat copper wire, and a punching through hole 19 is provided in the groove. The punching through hole is coaxially arranged with the guide hole. Secondary guide posts 8 are provided around the positioning plate, and the lower ends of the secondary guide posts 8 are fixed to the secondary guide post positioning plate. The secondary guide posts pass through the unloading plate 4 and extend out of the upper template. A rear buffer sleeve 10 is fitted on the secondary guide post 8. The buffer sleeve 10 is elastically supported between the unloading plate 4 and the upper template 7. The secondary guide posts 8 and the buffer sleeve 10 constitute a secondary positioning and guiding mechanism. An unloading bolt 14 is provided between the upper template and the unloading plate. A rectangular spring 15 is fitted on the unloading bolt. One end of the unloading bolt 15 is threaded to the unloading plate, and the other end is slidably engaged with the upper template. When pressed down, the upper template drives the punch to move and achieve punching. The unloading bolt and the rectangular spring constitute a tertiary positioning and guiding mechanism.

[0016] Both the lower template and the secondary guide post positioning plate have through holes coaxially arranged with the punching through holes.

[0017] In use, the wire is placed in the positioning plate 13, and pressure is applied through the press connecting seat 12 to punch holes. The primary guide post 2, the secondary guide post 8, and the unloading bolt 14 provide triple positioning to ensure accuracy. The positioning plate 13 fixes the wire in the horizontal direction. During unloading, the unloading spring 9, the buffer sleeve 10, and

[0018] Remove bolt 14 and restore it to its original position to remove the material.

[0019] When the punch 16 moves downward, it is compressed by the spring and comes out from the small hole below to cut flat copper or aluminum wire. When it moves upward, the punch will enter the unloading plate again.
