Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stamping die, in particular to a sheet metal part stamping die for packaging equipment processing. BACKGROUND

[0002] The stamping die is a special process equipment for processing materials into parts in cold stamping processing. The working principle is to use the die installed on the press to apply pressure to the material, so that the material produces plastic deformation, separation, etc. in the specific shape and size of the die cavity, thereby obtaining the required shape and size of the part. The press provides power to drive the relative movement of the upper die and the lower die of the die. The upper die is usually installed on the slide of the press, and the lower die is fixed on the workbench of the press. When the slide of the press goes down, the upper die goes down with it, closes with the lower die, and performs stamping processing on the material placed in the die cavity. When the slide goes up, the upper die rises with it, the die opens, and the stamped part or blank is taken out, completing a stamping cycle. The sheet metal part stamping die is a process equipment for stamping sheet metal materials to obtain parts with specific shape and size.

[0003] In the process of stamping and bending, in order to ensure the accurate direction in the stamping process, the guide is usually cleaned during stamping to remove impurities adhered to the surface of the guide. When removing impurities, a tool is usually used for scraping. However, in the process of scraping, the pressure cannot be buffered or when encountering large impurities, it will cause great wear to the guide, affecting the accuracy of the guide. SUMMARY
