Problems solved by technology

Moreover, around the cut-off point, it has a certain impact on the quality of the trimmed section of the workpiece.
It will cause defects such as burrs and other defects on the effective surface of the stamped workpiece corresponding to the position of the scrap cutter, which will seriously affect the surface quality of the workpiece
[0004] The edge trimmer block of the upper die is a consumable part, which needs to be disassembled and maintained or replaced frequently. However, in the existing stamping die, the edge trimmer block of the upper die has a complicated structure, and the disassembly and assembly work is cumbersome and time-consuming. caused great inconvenience

Description

technical field [0001] The invention belongs to the technical field of stamping parts processing, in particular to a stamping die with a rotating scrap knife and a stamping method thereof. Background technique [0002] In the trimming process of stamping die prior art, the upper die trimming knife of traditional mold is fixed, and the blade in cutting waste area will be higher than the blade in other trimming areas. The edge shape of the edge trimming knife has ups and downs, and the cutting edge of the edge is not synchronized when trimming. [0003] When trimming, the upper mold waste knife first pierces the workpiece, then trims the edge and then trims the edge. Debris is generated when the workpiece is pierced, and the debris will fall to the exposed surface of the workpiece, thereby scratching the surface of the workpiece. Moreover, around the cut-off point, it has a certain impact on the quality of the trimmed section of the workpiece. It will cause defects such as ...
