ow many automobile die characteristics do you know
In recent years, the rapid development of China's automobile industry has greatly driven the development of the automobile die industry. Because the automobile die is a technical product and a typical customized product, especially the technology content of the automobile panel die is very high. How to improve production efficiency, shorten development cycle, improve mold technology, reduce production costs has been a difficult problem for mold enterprises. Some new features in the mold manufacturing process: 1. Parallel production organization At present, concurrent engineering is widely used in mold production organization. Generally, the process of technical preparation, production preparation, mold processing and debugging in the mold development process should be parallel as much as possible, that is, production preparation, processing technology and NC program design should be parallel. The production plan must first arrange drawing and forming dies, then flanging and molding dies, then trimming and punching dies, and finally blanking and punching dies. Only in this way can we achieve balanced production and provide automobile factories with samples in advance 2. NC machining of solid type At present, mold manufacturers are basically using the real type manufacturing process. The NC machining production of the solid model is completed through the process editing of the solid model (such as the machining allowance of the machining surface, the layered editing of the model, etc.), followed by NC programming, foam blank blanking, NC processing, manual bonding and trimming. Thus, the production staff of the real mold has changed from manual production to a large number of numerical control programming. The simple manual bonding and finishing work on the site is performed by temporary workers. The numerical control production of the real mold directly improves the precision of the casting, bringing great advantages for the subsequent fine processing.
