The technical level of stamping die design and manufacturing is also a comprehensive standard to measure the technical capabilities of an enterprise. Mold manufacturing and design are directly related to the production efficiency, quality and production cost of stamping parts.

Stamping dies, which can be called cold stamping dies or cold stamping dies, are special processing equipment for processing materials in the cold stamping process. The material can be a metallic material or a non-metallic material. Stamping is a pressure processing method that is performed at room temperature. Install the mold on the press, apply pressure to the material to separate or plastically deform, and then obtain the required parts.

The materials used for stamping dies mainly include carbon steel, cemented carbide, low melting point alloy, zinc-based alloy, aluminum bronze, alloy steel, cast iron, cast steel, synthetic resin, polyurethane rubber, plastic, birch laminate, etc. , It can be metallic material or non-metallic material. The material of the mold is also very strict, requiring not only high hardness, high strength, high wear resistance, but also suitable toughness, high hardenability, no deformation during heat treatment, and no cracking during quenching.

In order to ensure the service life of the stamping die, it is necessary to select the die material reasonably and implement the heat treatment process correctly. The appropriate steel grade and heat treatment process should correspond to the different uses of the mold. In addition, attention should be paid to the working state of the mold, stress conditions, performance of processed materials, production batches and productivity, as well as the above requirements and performance.

According to the role of the stamping die in the combined structure, the structure of the die is mainly composed of process parts and structural parts. Process components directly participate in the process until the process is completed. And in direct contact with the blank, the process part mainly includes the positioning part, the working part, the unloading part and the pressing part. However, structural parts are completely different from craft parts. They do not directly participate in the process, and have no direct contact with the blank, but only to ensure the completion of the process or to improve the function of the mold. Structural parts mainly include fasteners, guide rails, standard parts, etc. However, it should be noted that not all stamping dies include these parts.
