线夹一模三件连续复合模设计(含选题审批表,任务书,开题报告,中期检查表,论文说明书11300字,CAD图纸17张)
摘 要：线夹一模三件冲裁模是一套倒复合模，它包括落料、冲孔、弯曲、切断四道工序。通过对冲裁机理及冲件工艺性的分析，设计出了结构合理、经济实用的模具；在制作过程中，保证加工零、部件的尺寸精度和表面质量，提高各零件间的位置对正关系，避免错位，调整好落料、冲孔的间隙，使得间隙值合理化，最终保证工件试冲后满足零件图所规定的精度要求。

Design of Wire Clip Three Cavties Progressive and Gang Die
Abstract： Wire clip three cavties progressive and gangdie is that one set gets the complex die, It including blanking , washing holes , crooked three processes of inverting to link a piece of blanking die. Through wash pieces of analysis of craft to blanking mechanism , design structure reasonable , economical and practical die; In the course of making , Guarantee to process precision of size of the spare part and surface quality, improve position of every part adjust relation well , Is it misplace to avoid , adjust good blanking , wash interval of hole, make interval to be value rationalized , Guarantee work piece is it meet part precision demand picture stipulate after washing to try finally.

模具总体结构设计
4.1 模具类型的选择
       由冲压工艺分析可知，采用复合冲压，所以模具类型为复合模。
4.2 定位方式的选择
 　  因为该模具采用的是条料，控制条料的送进方向采用导料销，有侧压装置。控制条料的送进步距采用导正销定距。
4.3  卸料方式的选择
     因为工件料厚0.8mm，相对较薄，卸料力不大，故可采用刚性料装置卸料。
4.4 导向方式的选择
 　为了提高模具寿命和工件质量，方便安装调整，该复合模采用对直导柱的导向方式。
