推件固定片级进模设计及其制造工艺

摘要本文主要通过分析对推件固定片零件的冲裁以及弯曲的生产工艺，了解了级进模的总体结构。分析比较了该零件的工艺方案，选定了模具形式是多工位级进模。通过对零件冲压工艺分析、冲孔-落料级进模零件的设计与计算、冲裁件整形、模具安装于调试、以及绘制装配图和零件图。其中还有推件固定片的零件冲压工艺性分析；确定冲压基本工序；排样方案的确定；连续模的送料定位系统的选用；冲裁模具凸凹模刃口尺寸的计算；模具主要零件尺寸计算；冲压力的计算；压力中心的计算；选择冲压设备；冲模的闭合高度；调整模具闭合高度等来讨论零件的冲裁。最后校核了冲压设备及确定了模具部件的材料和热处理要求。在模具结构绘制方面，借助于 AutoCAD 软件，绘制出模具的装配图和非标准件的零件图。本次设计对多次弯曲的零件的级进模设计有一定的深化了解，为日后的模具设计打下了基础。关键词：推件固定片，级进模，模具设计，结构设计AbstractThis paper mainly through the analysis to push a fixed piece of cutting and bending manufacturing process, understand the overall structure of progressive die. Analysis compared the processing plan of the parts and the mold form is selected multi-station progressive die. Through the parts stamping process analysis, punching and blanking progressive die design and calculation of blanking pieces, plastic parts, mould installation debugging, and draw the assembly drawing and part drawing. With a fixed piece parts stamping manufacturability analysis; Basic process to determine the stamping; The scheme determination of layout; Continuous mode selection of feeding positioning system; Blanking mould and die cutting edge dimension calculation; Die main parts size calculation; Burst pressure calculation; Calculation of pressure center; Choose stamping equipment; Die shut height; Adjust the height and so on to study a part of the blanking die closed. Finally check the stamping equipment and determine the mould parts material and heat treatment requirements.In term...
