Forming process and die design of control support
Abstract: It describes the progressive die design process and work through the process analysis system, using punching, blanking, flanging and other processes processing. To determine the die pressure center by computing technology force, press select models. Mold elastic unloading equipment. The mold structure is simple, reliable performance, and reduce labor intensity of the production capacity while improving production efficiency.
First analysis of the parts stamping process; to determine the overall structure of the mold; combination of parts stamping process and the overall structure of the mold design layout plan; layout diagram to calculate utilization, red contained, pressure, selection of equipment and the size of the cutting edge. Data re-use of PRO / E, mold design, then the three-dimensional map into a two-dimensional assembly drawings and parts diagrams to label.
Key words:Progressive Die,punching,Blanking,Flanging
