The upper die and the lower die are mounted on the fixing plates through the screw shafts, the pads and the bolts, mounting is stable, and demounting is convenient; the upper die and the lower die are provided with the oil inlet and the oil outlet, and the stamping die can be heated.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping die for automobile ceiling manufacturing, which belongs to the field of mechanical equipment manufacturing. Background technique [0002] Stamping die is a special process equipment for processing metal or non-metallic materials into parts or semi-finished products in cold stamping processing. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. In the stamping die, various metal materials and non-metal materials are used, mainly carbon steel, alloy steel, cast iron, cast steel, hard alloy, low melting point alloy, zinc-based alloy, aluminum bronze, synthetic resin, polyurethane Rubber, plastic, laminated birch boards, etc. The material for making molds requires properties such as high hardness, high strength, high wear resistance, ...

AI Technical Summary

Problems solved by technology

Today's car roof molds are inconvenient to replace. The same machine tool cannot produce different types of car roofs. The thermal conductivity is not good. It is impossible to combine forging molding and thermal molding, and the thickness of the processed parts cannot be adjusted to meet different processing needs.
