Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a thick plate square groove stamping die. Background Technique

[0002] A stamping die is a special process equipment for processing metal or non-metal materials into parts or semi-finished products in cold stamping processing. By using the die installed on a press to apply pressure to the material, it causes separation or plastic deformation. During the stamping process of the outer thick plate of the rear roof cover of an automobile, it is necessary to bend the outer thick plate into an arc shape design. Therefore, it is necessary to design a thick plate square groove stamping die.

[0003] The internal structure of the existing stamping die is relatively single, and most of them do not have a limiting mechanism inside. During later stamping, the thick plate is mostly directly placed on the top of the lower die groove. When bending, the two sides are not symmetrically bent, resulting in unqualified stamping products, increasing the waste phenomenon of stamping. Moreover, the thick plate during the stamping process is easily stuck inside the lower die groove, and later, operators need to use other extraction tools to take out the thick plate stuck inside the lower die groove, increasing the inconvenience and tediousness of later material extraction for this stamping die.
