The future development trend of stamping mould

The future development of stamping mould technology should take "fast delivery", "high precision", "high quality" and "low price" as the required standards. How can this be achieved? In order to meet this series of standards, we must develop these items in time:

Vigorously promote the CAD / CAM / CAE technology of mould. The CAD / CAM / CAE technology of mould can be called the future development trend of mould design. With the continuous development and progress of microcomputer software, the basic mature conditions have been reached to make the popularization of mould CAD / CAM / CAM / CAE technology, each mould industry and enterprises will also increase the training of CAD / C A M technology and the development of its technology services; expand the application of CAE technology in a larger scope.

Speed up the milling process. In recent years, the rapid development of foreign milling and processing industry, to a large extent to make the processing efficiency to improve, but also can make the surface of the finish to achieve a very high degree. In addition, the processing of high hardness module also has the advantages of low temperature rise and small thermal deformation. The rapid development of milling and processing technology, to the automobile industry, large and medium-sized home appliance industry type cavity mould manufacturing injection has also added a fresh power. From the current development degree, it has developed to a higher direction of agility, intelligence and integration.

Scan and digitize the mould. The high-speed scanner and mould scanning system provides many functions needed from the model or physical scan to process the desired model, greatly shortening the development and manufacturing cycle of the mould. Some fast scanning systems, can be quickly installed in the existing CNC milling machine and machining center, to realize fast data collection, automatic generation of various different CNC system processing procedures, different formats of CAD data, used for the mould manufacturing industry "reverse engineering". mould scanning system has been successfully applied in the automobile, motorcycle, home appliances and other industries, and I believe that it will play a greater role during the tenth Five-year Plan period.

Electric spark milling and processing. Electric spark milling processing technology is also known as electric spark into processing technology, this is a kind of alternative to the traditional forming electrode processing cavity new technology, it is a high-speed rotating simple tubular electrode for three-dimensional or two-dimensional contour processing, so no longer need to make complex forming electrode, this is obviously a significant development in the field of electric spark forming processing. Foreign machine tools using this technology have been used in mould processing. This technology is expected to be developed.

Improve the standardization degree of stamping mould. The standardization degree of stamping mould in our country is constantly improving stage, although in the current stamping mould standard parts coverage has reached about 30%, but relative to other countries, especially developed countries or a big distance, the foreign developed countries of stamping mould is the coverage generally can reach about 80%.

Material quality and advanced surface technology. It is very necessary to choose high-quality materials and apply the corresponding advanced surface treatment technology to improve the life of stamping moulds, such as choosing high-quality steel materials. The key to the performance of stamping mould steel is whether the heat treatment and surface treatment of stamping mould are more important. The future development trend of stamping mould heat treatment is the use of vacuum heat treatment technology. Not only to develop the surface treatment technology of stamping mould, but also to develop the advanced technology of vapor deposition (TiN, TiC, etc.), ion spraying and other advanced technologies.

The grinding and polishing of the stamping mould is automatic and intelligent. The quality of stamping mould surface can be said to the service life of stamping mould, stamping parts appearance quality of various aspects have great influence, research and invented the automatic, intelligent grinding method and polishing method to replace the manual operation method, which can improve the quality of the stamping mould surface, this is also an important development direction of stamping mould in the future

Develop the system of mould automatic processing. The development of stamping mould automatic processing can be said to be the long-term development goal of China's mould industry. The automatic machining system of stamping mould is mainly a reasonable combination of multiple machine tools, and is equipped with accompanying positioning fixture or positioning plate, which is quite complete; CNC flexible synchronization system is very complete, and a quite perfect monitoring and control system is set for quality.
