Abstract：

Through the technology analysis and theories calculation of the parts,the drawing coefficient of the product was got which was 0.46.Because it was bigger than 0.42 which was the first minimum drawing coefficient of the flanged cylindrical cups,the part could be drawed once and the technical scheme was improved.A compound die was used to finish the processes of blanking,drawing,and punchng. The whole structure character and working process about the clamp iron compound die were introduced.The results prove that the die is easy to be operated and reliable.The labour intensity and production cost are reduced,which can improve production efficiency by 3 times.The product's quality is guaranteened and the equipment utilization rate is raised by 2 times.The die has already produced near a hundred thousand products.The economical efficiency is remarkable.
