摘要
本套模具是一套沖孔、落料復(fù)合模。它的工序順序是第一步落料，第二步是沖孔。通過對沖孔、落料工件圖樣的工藝性的正確分析，設(shè)計了一個沖孔、落料復(fù)合模。首先對工件進行了工藝分析，確定了最佳工藝方案，并進行工藝計算；然后確定了沖孔、落料復(fù)合模的結(jié)構(gòu)型式，并對主要結(jié)構(gòu)零件進行了設(shè)計計算和強度校核；并合理的選擇了壓力機。通過本課題研究，使我掌握了沖壓模具設(shè)計的理論知識。
Abstract
This set of mold progressive die set punching, blanking level. The process sequence is the first step in a hole at the same time red and the surrounding three holes, the second step is a direct blanking. Through the correct analysis of the process of punching, blanking, workpiece pattern, design a punching, blanking, progressive die. Workpiece process analysis to determine the best process plan and process calculation; and then determine the punching, blanking progressive mode of the structure type, and the main structural components of the design calculations and strength check of; and reasonable choice for the press. Through this research, I mastered the theoretical knowledge of the stamping die design.
