The production process of cemented carbide cold heading die is as follows: 1. Design the mold: First, design a suitable cold heading mold according to the cold heading processing requirements and the size of the parts to be produced. Considering the characteristics of cemented carbide, ensure that the mold has sufficient hardness and wear resistance. 2. Select material: choose suitable cemented carbide material as the raw material of the mold. Commonly used cemented carbide materials include tungsten-cobalt alloys. 3. Material processing: processing the selected cemented carbide material usually includes the following steps: a. Cutting: According to the design size of the mold, use cutting tools to cut the material into blanks of the required shape. b. Rough machining: use tools such as milling machine and drilling machine to rough the blank to make the basic mold shape. c. Finishing: Use precision machining equipment such as grinding machines and wire cutting machines to finely process the mold to meet the required geometric shape and size requirements. d. Surface treatment: According to the needs, the mold can be surface treated, such as heat treatment, electroplating, etc., to improve the hardness and wear resistance of the mold. 4. Assemble the mold: Assemble the processed parts to ensure that the structure of the mold is firm and the function is intact. 5. Debugging and testing: Test the performance and reliability of the mold, including the wear resistance of the mold, cold heading effect, etc. 6. Use and maintenance: When using the mold, regular maintenance and maintenance, including cleaning, lubrication, etc., will prolong the service life of the mold and keep it in good working condition. In short, the production process of cemented carbide cold heading dies involves multiple links such as design, material selection, processing, assembly, debugging and maintenance. It is necessary to ensure that the dies have sufficient hardness and wear resistance to meet the requirements of cold heading processing.
