ABSTRACT
According to the graduation project guidance teacher arrangement, subject name for the cover design of rectangular composite mold. From the topic given by the parts of the map, combined with the structure and the shape size. Firstly, it analyzes the process of workpiece type, according to the size of the workpiece, analysis and selection of suitable design; secondly, die arrangement of sample design, access to relevant data, calculation of blank size of workpiece, reasonable choice of nesting take the boundary value; finally, the calculation of the die pressure center and flushing pressure, corresponding to the press; finally choose between mold standard, drawing mold assembly drawings and part drawings and prepare design specification. In addition, combining the workpiece structure, from the point of view of the production of in order to save the mold manufacturing costs, improve production efficiency, ensure the production precision of the workpiece, the workpiece punching blanking die design of the compound die of blanking. In the mold design mainly find the workpiece drawings unlabeled tolerances of tolerance, according to the dimensional tolerances to determine precision mold manufacturing, after multiple layout analysis to design of mold structure.
Keywords composite die; blanking force; gasket; blanking clearance; pressure center
