Description

Technical Field

[0001] The utility model belongs to the technical field of punching dies, and particularly relates to a punching die with a disassembly and assembly structure. Background Technique

[0002] A die refers to various dies and tools used in industrial production for injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, etc. to obtain the required products. In machining production, it is often necessary to open holes or slots in metal parts, so punching die blanking processing is adopted to improve production efficiency.

[0003] At present, after the metal parts are processed by a punching die, the remaining chips will fall on the lower die. In order to ensure normal punching in the follow-up, manual cleaning is required, or a special cleaning mechanism is added to complete the cleaning. However, the manual cleaning work efficiency is low, and adding a special cleaning mechanism will increase the occupied space and manufacturing cost of the entire punching die. A punching die is disclosed in the publication number CN105344803B. This patent only uses the upper die structure to achieve the function of rapid chip removal, but there are great limitations in application. Therefore, how to achieve rapid chip removal on a punching die with upper and lower dies is a problem that needs to be solved urgently at present. Content of the Utility Model
