The key stamping process analysis and mold design Guolin Wang Shandong Transport Vocational College ,Shandong Weifang ,261206,China; E-mail: 572407372@ Key words: key, stamping, process, mold Abstract: key production into mass production, the aluminum alloy material, including punching, blanking, two working procedure, precision parts, determine the first punch blanking, after adopting progressive die production. For mould design and calculation, and the convex model component and its structure, die components, positioning parts, unloading and push the pieces of parts to carry on the design, to complete the mold assembly drawing. 1. The stamping technology analysis of blank keys As shown in figure 1, parts production to mass production, the material is 2 mm thick aluminum alloy plate. There is hole. The artifacts including punching, blanking, two working procedure, precision parts, all take the free size of workpiece, ordinary mold can meet. Fig.1 Key part drawing 2. The scheme determination of stamping The artifacts including blanking, punching and cutting edge, can have the following plan: Scheme 1: punching blanking, after first USES the level into a mold production. Scheme 2: blanking - bending - punching compound stamping, with composite mold production. Focus two mould process, forming at a time. But abrasive complex, various parts of the processing difficulty is big, need more parts and complex; Plan a need a pair of mold production efficiency while the mould structure complex but simple geometry mould manufacturing is not difficult, because parts by comparing these methods, the scheme adopts the scheme one is preferred. 3. The layout and sure Stamping on the strip or sheet metal decorate a method known as the layout. Layout of the principle is the same as the ordinary cutting. If parts are not required to rolling direction of the material, the layout of the aim is to ensure that process needs and ensure that the workpiece cutting
