In our country, mould manufacture belongs to special equipment manufacturing industry. Mould industry is automotive product development and an important part of mass production. Car front axle oil seal cover as one of the parts of the car, along with the high speed development of auto industry. It needs high-speed production efficiency, and the presswork needs to achieve high precision in order to satisfy the required safety performance. For this premise, analysis its appearance characteristics, considering the finished product complete blankingdeep drawingtrimmingflangingpunching, a total of five processes. Through the analysis of process and determined the suitable for a given the best process program production conditions, combination of three molds. That is, gang dies of blanking and deep drawing, singleprocess mode stamping trimming stamping, gang dies of flanging and punching. Analyze stamping process of workpiece，determine the flange nature, parts drawing parts size requirement, deep drawing number, trimming surplus, and calculated the blank dimensions, complete blank layout design; According to the fillet radius, the gap between die and punch, dimension tolerance, calculate the convex, concave die size, determine the length of the punch, concave die thickness; Calculating the die the blunt pressure, complete the die design of unload device, block material pin, ejector device, pushing a device structure, and press specifications choice; According to the punch, concave die size selection of formwork, guide pin, guide set, die handle, pad, fixed board; For each vice the working process of the die, die assembly process makes a detailed instruction, and to mould the punch, concave die, die and punch processing technology is analyzed.To draw assembly drawing and parts drawing. Accomplish the analyze stamping process of workpiece and mold design.
