Description

Technical Field

[0001] The utility model belongs to the field of stamping dies and relates to a stamping die with a protective structure. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. Most of the existing stamping dies use cylinders as the power element for maintaining pressure. When changing or repairing the mold, the upper mold under the upper mold fixing plate and the lower mold on the frame workbench need to be removed and replaced with a new mold. Due to the lack of necessary protective structures, the cylinder needs to select the upper mold in the air so that the staff can remove or repair it. In this state, there are great safety hazards.
