Manufacturing process of cemented carbide die tools forming parts

       

Manufacturing process of cemented carbide die tools forming parts. The manufacturing process of forming parts and the type of processing technology, modern cemented carbide mold manufacturing process has been very simplified. Among them, the standard parts of the mold not only meet the assembly requirements in accuracy and quality, but also can be purchased from the market. The blanks of the formed parts, Including forgings and rolling templates, it can also be purchased from the market. Therefore, the main process content in the manufacturing process of cemented carbide molds is only the two main process content of the manufacturing process of the formed part and the mold 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 molded parts, including quenching, nitriding process and surface strengthening process, etc.

 

3. Finishing processing of the molding surface, including plastic mold cavity skin processing, polishing and grinding processing.

 

Stamping die tools

 

It can be seen that the forming process of the molding surface of the stamping die tools and the forming mold has become a key processing technology. The following methods are commonly used in the forming process of the forming part:

 

 

 

1. The CNC forming and milling process is the main process method for the processing of plastic injection molds, die tools-casting molds and other forming molds, especially the application of high-speed milling process, 4-5 axis linkage processing technology, 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 surface roughness value and reduce the workload of grinding and polishing.

 

3, CNC, precision coordinate hole system processing technology

 

4. Numerical control and precision wire-cut EDM processing technology is often used in the final processing procedures of general die tools forming parts, and also used in the pre-processing of high-precision mold forming parts.

 

5. Precision forming and grinding processing technology, mainly used for precision forming processing of punching die tools, concave die tools and punch block

 

6. Extrusion forming process of forming mold cavity, precision casting forming process, the former is mainly used for simple shape and shallower cavity processing, and the latter is mainly used for the forming of large cavities in the cavities of automobile calendering die toolss, etc. .
