The nine major development trends present in the automotive mold industry at home and abroad

1. Mold three -dimensional design status can be consolidated

The three -dimensional design of the mold is an important part of digital mold technology, and it is the basis for achieving the integration of mold design, manufacturing and inspection. Japan Toyota, GM, and other companies have achieved three -dimensional design of the mold and achieved good application results. Some methods adopted in the three -dimensional design abroad are worthy of our reference. In addition to being conducive to the integrated manufacturing, the other advantage is that it is convenient for interference inspections, exercise interference analysis, and solving a problem in the two -dimensional design.

2. Simulation (CAE) effect of stamping formation process is even more prominent

In recent years, with the rapid development of computer software and hardware, the simulation technology (CAE) of stamping formation process has played an increasingly important role. In developed countries such as the United States, Japan, and Germany, CAE technology has become a necessary link for mold design and manufacturing. It is widely used to predict forming defects, optimize the stamping process and mold structure, improve the reliability of mold design, and reduce the time testing time. Many domestic automotive mold companies have made significant progress in the application of CAE and have achieved good results. The application of CAE technology can greatly save the cost of test models and shorten the development cycle of stamping molds, which has become an important means to ensure the quality of molds. CAE technology is gradually transforming mold design from experience design to scientific design.

3. Digital mold technology has become the mainstream direction

In recent years, the rapid development of digital mold technology is an effective way to solve many problems facing car mold development. The so -called digital mold technology is the application of computer technology or computer auxiliary technology (CAX) in the process of mold design and manufacturing. Summarize the successful experience of computer -aided technology for automotive mold enterprises at home and abroad. Digital automotive mold technology mainly includes the following aspects: ① Manufacturing (DFM), that is, considering and analyzing the manufacturer in design to ensure the success of the process. ② Auxiliary technology of mold -type design, develop intelligent facial design technology. ③ CAE auxiliary analysis and simulation stamping process process, predict and solve possible defects and formation problems. ④ Use a three -dimensional mold structure to design the traditional two -dimensional design. ⑤ The manufacturing process of the mold adopts CAPP, CAM and CAT technology. ⑥ Under the guidance of digital technology, deal with the problems that occur during the test mode and the problem of stamping production.

4. The rapid development of mold processing

Advanced processing technology and equipment are an important foundation for improving productivity and ensuring product quality. It is not uncommon for advanced car mold companies to be equipped with dual -control machine tools, automatic knife -changing devices (ATC), automatic processing photoelectric control systems, and online measurement systems of workpieces. CNC processing has developed from simple facial processing to comprehensive processing of type and structural surface, from low -speed processing to high -speed processing, and the development of processing automation technology has developed very rapidly.

5. High -strength steel plate stamping technology is the future development direction

Due to excellent characteristics in high -strength steel in terms of flexion ratio, strain hardening characteristics, strain distribution capacity, and collision energy absorption, the amount of use in the car continues to increase. At present, high -intensity steels used on automotive stamping parts include paint hardening steel (BH steel), double -phase steel (DP steel), and phase change -induced plastic steel (TRIP steel). 97%of the materials launched in 2010 are expected to be launched in 2010, which is expected to be launched in 2010. The proportion of steel will account for 74%of the steel plate.

A large number of IF steel series adopted now will be replaced by high -strength steel plate series, and high -strength low -alloy steel will be replaced by double -phase steel and ultra -high -strength steel plates. At present, the application of high -strength steel plates in domestic automobile parts is mostly limited to the structural components and beams, and the tensile strength of the materials used is below 500MPa. Therefore, quickly mastering high -strength steel plate stamping technology is an important issue that my country's automotive mold industry needs to solve.

6. New mold products are launched in time

With the efficient development and automation of automotive stamping production, the application of class modules will be widely used in the production of automotive stamping parts. Grade Model is a high -tech mold product, which is difficult to technology, high manufacturing accuracy requirements, and long production cycle. Multi -site -level models will be one of the key mold products in my country. Complicated stamping parts, especially some, especially some According to the traditional process, the small and medium -sized complicated stamping parts are required for multiple sub -molds, and more and more levels of grade inlet formation are adopted.

7. Mold material and surface treatment technology will be reused

The quality and performance of mold materials are important factors that affect the quality, life and cost of mold. In recent years, in addition to the launch of a variety of high tough and high -resistant cold -resistant cold -working mold steel, flame quenching cold work steel, and powder metallurgy -cold mold steel, foreign and medium -sized stamping molds are used to use cast iron materials. Follow the development trend. The ball and cast iron have good toughness and abrasion resistance. Its welding performance, processability, and surface quenching performance are also better, and the cost is lower than that of the alloy cast iron, so it is used more in automotive stamping molds.

8. The scientific and informatization of management is the development direction of mold enterprises

Another important aspect of the development of automotive mold technology is the scientific and informatization of management. The scientific management of the management has continuously developed the direction of Just-in-TimemanUfacturing and Leanproduction. Enterprise management is more accurate, productive efficiency has been greatly improved, and invalid institutions, links and personnel are continuously streamlined. With the advancement of modern management technology, many advanced information management tools, including enterprise resource management systems (ERP), customer relationship management (CRM), supply chain management (SCM), project management (PM), etc., in mold enterprises, etc. Get widely used.

9. The refined manufacturing of the mold is an inevitable trend

The so -called refined manufacturing is for the development process and manufacturing results of the mold. The specific manifestation is the rationalization of stamping process and mold structure design, the high precision of mold processing, the high reliability of mold products, and the strict technical management of technical management sex. The refined mold manufacturing is not a single technology, and the second is the comprehensive reflection of design, processing and management technology. The realization of the refined manufacturing of the mold is in addition to relying on technical excellence, but also to be guaranteed by strict management.
