Abstract：In recent years, the rapid development of China's household electrical appliance industry mould industry, especially cold blunt mould put forward more and more high demand, in 2004, cold in the whole mold industry rush mold the proportion of has greatly rising, experts predict, in the next few years, China cold blunt mould industry will continue to keep an annual growth rate of 15% or so of the high speed development. Stamping forming is the metal forming a kind of important method, it is mainly applied to materials softer metal forming, can be a complex shape of precision stamping forming. This topic is will petrochemical, chemical, electric power industries of the flange gasket seal structure design model, as will the related knowledge of cold blunt mould as basis, this paper expounds the design process of cold blunt mould.

The graduation design is complete motorcycle centrifugal block stamping process and mold design. Adopt blanking, deep drawing, punch, deburring process. In the design of workpiece stamping technology analysis, calculated blank layout, blunt pressure, the blade size calculation, etc. The major parts of the overall structure, mould design, painted blanking, deep drawing, punching composite modulus, trimming single procedure mold assembly drawing and parts drawing. This topic through centrifugal blocks of motorcycle fixed board design, strengthening and deepening the knowledge learnt, achieved satisfactory effect, achieve the expected design intent.
