摘    要

冲压模具在实际工业生产中应用广泛，随着当今科技的发展， 工业生产中模具的使用已经越来越引起人们的重视，而被大量应用到工业生产中来。冲压模具可以大大的提高劳动生产效率，减轻工人负担，具有重要的技术进步意义和经济价值。本文针对端盖的冲裁工艺性和拉深工艺性，分析比较了成形过程的三种不同冲压工艺（工序、复合工序和连续工序），确定用一幅复合模完成落料、拉深和冲孔的工序过程。介绍了端盖冷冲压成形过程，且简要分析了坯料形状、尺寸，排样、裁板方案，拉深次数，冲压工序性质、数目和顺序的确定。进行了工艺力、压力中心、模具工作部分尺寸及公差的计算，并设计出模具。还具体分析了模具的主要零部件（如凸凹模、卸料装置、拉深凸模、垫板、凸模固定板等）的设计与制造，冲压设备的选用，凸凹模间隙调整和编制一个重要零件的加工工艺过程。列出了模具所需零件的详细清单，并给出了合理的装配图。通过充分利用现代模具制造技术对传统机械零件进行结构改进、优化设计、优化工艺方法能大幅度提高生产效率，这种方法对类似产品具有一定的借鉴作用。

Abstract
Stamping die in the actual industrial production is widely used, with today's technology development, industrial production has become increasingly used in the mold of attention has been paid, and have been widely applied to industrial production in the past. Stamping can greatly improve labor productivity, reduce the burden on workers, has an important significance of technological progress and economic value. In this paper, and cover the blanking process of deep drawing process, the forming process of analysis and comparison of three different stamping processes (processes, composite processes and continuous processes), to determine the complete model with a composite blanking, drawing and red hole of the process process. Presented cover the cold stamping process, and a brief analysis of the blank shape, size, nesting, cutting board plan, drawing number, the nature of the stamping process, number and sequence determination. For the technological edge, center of pressure, mold dimensions and tolerances of the working part of the calculation and design mold. Also detailed analysis of the major components of the mold (such as punch and die, discharging device, drawing punch, plate, fixed plate punch, etc.) design and manufacturing, stamping equipment selection, adjustment and preparation of punch and die clearance is an important machining process. Lists the components required for a detailed list of die, and gives a reasonable assembly drawing. By taking advantage of modern technology on the traditional mold manufacturing mechanical parts for structural improvements, optimization, process optimization method can significantly improve production efficiency, this method has a similar product for reference.
