Manufacturing process of cemented carbide die forming parts. Forming parts manufacturing process and its processing types, modern cemented carbide die tools manufacturing process has been very simplified. Among them, die tools standard parts, not only accuracy and quality have been able to meet the assembly requirements, but also can be purchased from the market, forming blanks, Including forgings and rolling templates, it can also be purchased from the market. Therefore, the main process content of the cemented carbide die tools manufacturing process is only the two main process content of the manufacturing process of the formed part and the die tools assembly process.
The manufacturing process and sequence of forming parts are:
1. Forming processing of formed parts, including hole system processing, groove and plane processing, etc.
2. Finishing processing of the die toolsing surface of the formed part, including quenching, nitriding process and surface strengthening process, etc.
3. Finishing processing of the die toolsing surface, including plastic die tools cavity skin processing, polishing and grinding processing.
It can be seen that the forming of the die toolsing surface of the stamping die and the forming die tools has become a key processing technology, and the following methods are commonly used in the forming of forming parts:
1. Numerical control forming and milling process is the main process method for plastic injection die toolss, die-casting die toolss and other forming die tools forming parts, especially the application of high-speed milling process and 4-5 axis linkage processing technology, which has become the main method of modern processing technology for forming parts .
2. EDM processing technology is often used for general precision forming cavity processing, and it is often used for precision processing of formed parts after forming and milling to reduce the value of surface roughness and reduce the workload of grinding and polishing.
3, CNC, precision coordinate hole system processing technology
4. Numerical control, precision wire-cut EDM processing technology is often used in the final processing procedures of general die forming parts, and also used in the pre-processing of high-precision die tools forming parts.
5. Precision forming and grinding processing technology, mainly used for precision forming processing of punching die, concave die and punch block
6. Extrusion die toolsing process of forming die tools cavity, precision casting die toolsing process, the former is mainly used for simple shape, shallower cavity processing, and the latter is mainly used for automobile calendering die cavities, etc., large-scale cavities forming .
