Abstract The content of the subject is the process analysis and die structure design for contact piece parts。 Access to relevant literature, first of all for this part process analysis of the film is contacted, optimal process plan is identified and selected, then calculating about the process analysis and design of die, such as basic processes, the determination of the process sequence, the number of processes and process combination form。 Pressure force machine is selected and checked, parts stamping row sampling is determined, Finally, the design scheme of the assembly is determined by the combination of progressive die and bending die。 The design process of multi station progressive die is introduced in detail。 In the design of bending die, the bending force is calculated, and the stroke of the slide block of the press is determined。 The bending die is provided with a pressing block to prevent the part from slipping during the bending process。 The pressing block is towed by a spring, and the appropriate spring is selected according to the size of the material, The material of the spring and the outer diameter of the outer ring, the diameter of the steel wire, the maximum load and so on are determined。 In order to determine the optimal value of the material, the influence of the change of the material on the bending results in the bending process is simulated。 The effect of the medium pressure material force on the bending deformation is simulated。
Keywords: Multiple station progressive die; bending; Dynaform simulation; optimal design
