A stamping die for VCT powder metallurgy parts

technical field

The utility model relates to a stamping molding die for VCT powder metallurgy parts, which belongs to the technical field of stamping molding processing mold equipment.

Background technique

At present, in the VCT parts used in automobiles and other equipment, in order to improve their structural lightness and processing accuracy, alloy materials with extremely high hardness are used as the main material, which makes it difficult for such parts to be processed by traditional machining. Therefore, in order to solve the forming process of such parts, powder metallurgy technology is used to process parts. Although powder metallurgy technology can meet the production requirements of such parts, it will inevitably increase the production cost of such parts. , and the disadvantages of relatively low production efficiency, so it cannot effectively meet the use needs of such parts. Therefore, how to realize the traditional machining can effectively meet the processing needs of VCT parts has become the current solution to the insufficient production volume and production cost of VCT parts. The main way of being too high.
