Dynaform摘要此次课题的内容是针对接触片零件的工艺分析和模具结构设计。查阅相关的文献资料，首先对接触片这个零件进行工艺分析，确定并选择较优的工艺方案，在工艺分析和模具设计方面进行相关的计算，如基本工序、工序顺序、工序数目以及工序组合形式，压力机的选择与校核，零件冲压排样方式的确定等，最终确定由级进模与弯曲模相结合的工装设计方案。详细介绍了多工位级进模的设计过程。在弯曲模的设计过程中，计算了弯曲力，确定压力机上滑块的行程。弯曲模上设有压料块，以防止零件在弯曲过程中发生滑移。压料块由弹簧牵引，根据压料力的大小选择合适的弹簧，确定弹簧的材料以及弹簧的外圈直径、钢丝直径、最大负荷等。为了确定压料力的最佳值，在弯曲过程中，模拟压料力的改变对弯曲结果产生的影响。弯曲过程中压料力大小对弯曲变形的影响进行仿真模拟。83531

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
