5G part stamping die and stamping method

Abstract

The invention relates to the technical field of metal plate stamping, and particularly discloses a 5G part stamping die and stamping method. The 5G part stamping die comprises an upper die unit and alower die unit, wherein the upper die unit comprises a guide column, the lower die unit comprises a guide sleeve corresponding to the guide column, and the guide column is in sliding fit with the guide sleeve; the upper die unit further comprises a bending punch obliquely arranged, the lower die unit further comprises a bending assembly, the bending assembly comprises a bending lower die and a first spring arranged at the lower end of the bending lower die, and the bending lower die rebounds under the action of the first spring; and the bending lower die is in an inverted trapezoid shape and comprises an upper supporting face, a lower connecting face, a left sliding face and a right bending face, and the obliquely-arranged angle of the bending punch is the same as the oblique angle of theright bending surface. According to the 5G part stamping die and stamping method, the appearance quality, the production reliability and the production stability of stamped parts can be effectively guaranteed, meanwhile, the forming procedure can be favorably simplified, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of sheet metal stamping, and specifically discloses a stamping die for a 5G part and a stamping method thereof. Background technique [0002] There is a kind of edge pressing feature in the box parts of communication, new energy, and electronic products. During the edge pressing process of parts, the appearance is required to be free of chipping, scratches and wear marks. The current molding process includes edge pressing and edge pushing. [0003] Such as figure 1 and figure 2 as shown, figure 1 It is the mold opening state diagram of the existing blank holder mold, figure 2 It is the closed mold state diagram of the blanking die, the existing blanking die includes a stripping plate 16, a lower stripping plate 27, a bending punch 12 and a lower template 26, from figure 1 and figure 2 It can be seen that during the forming process, the bending punch inevitably exerts force on the corner position of ...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 and figure 2 as shown, figure 1 It is the mold opening state diagram of the existing blank holder mold, figure 2 It is the closed mold state diagram of the blanking die, the existing blanking die includes a stripping plate 16, a lower stripping plate 27, a bending punch 12 and a lower template 26, from figure 1 and figure 2 It can be seen that during the forming process, the bending punch inevitably exerts force on the corner position of the end face of the product part and continues to squeeze and slide displacement during the forming process, resulting in edge burrs, powder falling and bending The outer surface causes crushing and scratches, which reduces the quality of the product
