The simulation of the stamping process (CAE) is more prominent
In recent years, with the rapid development of computer software and hardware, the simulation technology of stamping process (CAE) has played an increasingly important role. In the developed countries such as the United States, Japan, and Germany, CAE technology has become an essential part of the mold design and manufacturing process. It is widely used to predict forming defects, optimize stamping processes and mold structures, improve the reliability of mold design, and reduce the time for mold testing. Many domestic auto mold companies have also made significant progress in the application of CAE and achieved good results. The application of CAE technology can greatly save the cost of trial mold and shorten the development cycle of stamping mold, which has become an important means to ensure the quality of mold. CAE technology is gradually transforming mold design from empirical design to scientific design.
The status of mold 3D design is consolidated
The three-dimensional design of the mold is an important content of digital mold technology and the basis for the integration of mold design, manufacturing and inspection. Companies such as Toyota of Japan and General Motors of the United States have realized the three-dimensional design of the mold and achieved good application results. Some of the foreign practices adopted in the 3D design of the mold are worthy of our reference. In addition to the three-dimensional design of the mold, which is conducive to integrated manufacturing, another advantage is that it is convenient for interference inspection and can perform motion interference analysis, which solves a problem in two-dimensional design.
Digital mold technology has become the mainstream direction.The rapid development of digital mold technology in recent years is an effective way to solve many problems faced in the development of automotive molds. The so-called digital mold technology is the application of computer technology or computer-aided technology (CAX) in the mold design and manufacturing process.Summarizing the successful experience of applying computer-aided technology in domestic and foreign automobile mold enterprises, digital automobile mold technology mainly includes the following aspects:
① Manufacturability design (DFM), that is, considering and analyzing manufacturability during design to ensure the success of the process.
②Auxiliary technology for mold profile design, develop intelligent profile design technology.
③ CAE assists in analyzing and simulating the stamping process, predicting and solving possible defects and forming problems.
④Replace traditional two-dimensional design with three-dimensional mold structure design.
⑤CAPP, CAM and CAT technologies are used in the manufacturing process of the mold.
⑥ Under the guidance of digital technology, deal with the problems in the process of trial mold and stamping production.
