Mold CAD \/ CAM technology can significantly shorten the mold design and manufacturing cycle, reduce production costs and improve product quality. During the “Eighth Five Year Plan” and “Ninth Five Year Plan”, a large number of mold enterprises have popularized computer drawing technology, the utilization rate of NC machining is also higher and higher, and a considerable number of CAD \/ CAM systems have been introduced one after another. For example, UG of EDs in the United States, Pro \/ Engineer of parametric technology in the United States, cads5 of CV in the United States, doct5 of Delcam in the United Kingdom, crade and space-e of HZS in Japan and Cimatron of Israel have also introduced AutoCAD, CATIA and other software and Euclid is and other special software for automobile and panel molds of Marta daravision in France. CAD \/ CAM technology is widely used in domestic automobile panel die manufacturers. The design of DL drawing and die structure drawing have realized two-dimensional CAD. Most enterprises have made a transition to three-dimensional, and the general drawing production has gradually replaced the part drawing production. And the parametric design of mold also began to move towards the field of technical development of a few mold manufacturers.<\/p>\n\n\n\n

Under the correct guidance of the national industrial policy, after decades of efforts, China’s stamping die design and manufacturing capacity has reached a high level. Many modern design and manufacturing technologies, including information engineering and virtual technology, have been applied in many die enterprises.<\/p>\n\n\n\n

Nevertheless, there is still a big gap between China’s stamping die design and manufacturing capacity, market needs and international advanced level. These are mainly reflected in the dies and high-precision stamping dies for high-end cars and large and medium-sized automobile panels. There is a big gap in design, processing technology and capacity. The car panel die has the characteristics of great difficulty in design and manufacturing and high requirements for quality and precision, which can represent the level of panel die. Although the design and manufacturing methods and means have basically reached the international level, the mold structure and function are close to the international level, and a big step has been made in the process of car mold localization, there is still a certain gap compared with foreign countries in terms of manufacturing quality, precision and manufacturing cycle.<\/p>\n\n\n\n

The degree of specialization of China’s mold industry is still relatively low, and the proportion of self-produced and self-made molds is too high. The proportion of self-produced and self-made molds in foreign countries is generally 30%, and the proportion of self-produced and self-made stamping molds in China is 60%. This has had many adverse effects on specialization. Now, the molds with high technical requirements and large investment have a high degree of specialization, such as panel molds, multi station progressive dies and precision dies. The degree of specialization of general die is low. Due to the high proportion of self matching, the distribution of stamping die production capacity basically follows the distribution of stamping part production capacity. However, the distribution of professional production enterprises of automobile panel dies and multi station and multi-functional precision dies with a high degree of specialization does not follow the distribution of stamping capacity, but often depends on the decision-making of major investors. For example, Sichuan has a large capacity of automobile panel die, Jiangsu has a strong capacity of precision die, and most of the die users are not local.<\/p>\n\n\n\n

In the actual production, when the production batch of stamping parts is large, the size is small and the tolerance requirements are small, it is uneconomical or even difficult to meet the requirements if stamping with a scattered single process. public platform of molder magazine: at this time, centralized schemes are mostly adopted in the process, that is, two or more single processes are completed in one pair of molds. The combination methods are different, and they can be divided into three Compound stamping – a combined combination methods: Compound progressive and compound progressive.<\/p>\n\n\n\n

Progressive stamping — the first mock exam of a press is a combination of two or more than two different single processes in different positions of the same mold in a certain sequence.<\/p>\n\n\n\n

1. Concept and advantages of stamping 1.1 concept of stamping Stamping is a pressure processing method that uses the die installed on the stamping equipment (mainly Press) to exert pressure on the material to produce separation or plastic deformation, so as to obtain the required parts (commonly known as stamping or stamping parts).
