The Compound Die Design of Forming Chuck
Abstract: The design of artifacts can be made with many sets of mold design method, But the process cycle is too long and the efficiency is too low. In the transforming course of the mould is difficult to guarantee the size of the work piece and technical requirements. The most important thing is that many sets of mold cost is higher, is not in conformity with the current mold development present situation. After analysis, determine using compound die blanking of a method of forming parts performed by a complex die blanking, punching and bending. And complete the process, the calculation of die cutting edge dimension, as well as the press check, etc. The design of the components is necessary to adopt a blanking. Due to restrictions on the size, structure, production of the best parts with composite mold production and it is necessary to use elastic discharging device.
Key words: compound die; mold design; chuck artifacts
