This workpiece material used in steel 10 and thickness of 0.8mm to ensure sufficient strength and rigidity, the parts with complicated shape, cumbersome process, so the design into a progressive die for punching, to protect the small punch in the blanking process. Reasonable layout, reduce waste. Materials for the high quality carbon steel, stamping processing economy is good.Firstly, the process analysis of the part, and then choose the progressive die as the process of the mold production plan, through the calculation of the main computational analysis to complete the mold design, design and calculation of convex, concave die part of work, the main components of the structural design,. Completion of a series of calculations, and draw the assembly diagram, punch and die with the map design, mold the necessary drawings. Most programs of mould design.Stamping is designed according to the existing production conditions, comprehensive consideration of various factors to affect the production process, reasonable arrangements for the production process parts, optimal selection, size and range, determine the technical parameters of die design, selection of equipment, so that the entire production process to achieve high quality parts, hig
