In recent years, with the rapid development of China's aviation manufacturing industry and the automobile industry, stamping die every year in the growth rate of 20%. Stamping die stamping production is essential for the process and equipment, is a technology intensive products. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of die and mould. As in a life cycle model, the shortest, the most frequent changes is the body, the body key lies in the development of the design and manufacture of car body stamping die, accounting for vehicle development time of 2/3, is a key factor constraining the car quickly listed.
In our country, the import of mold to occupy the domestic high-end mold market about 50%. Compared with the international advanced level, we still have a gap of about 5~10 in the large-scale, precision and complexity of high technology and high technology content. In the stamping die manufacturing industry, the gap is mainly manifested in the precision, stability and reliability, life cycle and manufacturing and other aspects of the use of digital design, mold manufacturing technology is one of the main reasons behind the cause behind the product. How to deliver high quality tooling to users in a limited period of development, need to improve the technology and management of stamping die.

Mold design and manufacturing enterprise information management of digital technology (including digital design, processing, analysis and information management in the manufacturing process, the mold CAD/CAE/CAM/DNC Technology) is an effective means to improve the overall level of international mould industry, can greatly improve the production efficiency and product quality of the mold, and enhance the overall level and efficiency of enterprises the.

Key technology of digital design and manufacture of mould

With the rapid development and popularization of digital technology, digital technology has been applied to the whole process of mold manufacturing. From the analysis of Figure 1, it is shown that the digital technology is an important factor which restricts the development of stamping die. The digital technology of mould is the application of computer technology and computer aided technology in the design and manufacture of die and mould. Summing up the successful experience of the application of computer aided technology in stamping die enterprises at home and abroad, according to the stamping die manufacturing process, digital stamping die technology is mainly reflected in 4 aspects.

Synchronous development of stamping process throughout the whole process of new products, from the understanding of the product process, to the stamping process of the product analysis, and then to the development of the mold are required to participate in the entire process of stamping process. Stamping CAE technology is the actual physical law from the stamping process, with the help of the computer to truly reflect the interaction between the mold and the sheet material and the whole process of the actual deformation of the sheet.
