摘 要

本文是对拉深件进行工艺分析及模具设计。该工件是一个圆筒形拉深件，另外该工件的底部带有通孔，需进行冲孔翻边，虽然形状不太复杂但肯定不能一次成形。通过对零件各部分进行计算分析后才能最终确定加工工序。工件整个成形过程所涉及的工序有：落料、拉深、冲孔、翻边等四步。通过计算分析得翻边能一次成形，所以不需进行预拉深，而计算可知拉深可一次成形，所以确定最终工艺方案为：落料与拉深复合，冲孔、翻边复合。在确定工艺方案的基础上对主要模具进行设计，分析工件成型过程，设计模具的结构并画出模具装配图及零件图。在本次设计中主要对落料拉深复合模以及冲孔、翻边模进行设计。

ABSTRACT
The thesis is focus on the process analysis and mold design of the drawing.The workpiece we design is a cylinder-shaped drawing parts,which has a hole at the bottom.The workpiece should be punched and flanged.Although the shape is not very complex,it couldn’t be shaped by one step.We can determine the processing by analyzing the parts of the workpiece.The process include several steps:blanking,drawing,punching and flanging.By analysis,we know that the flanging can be finished by one step.There should not be a pre-drawing.However,the drawing can be achieved easily.Therefore,the final process is compounding the blanking with the drawing, the punching die and flanging die.Besides,we should design the main die,analyse the process,design the structure of the die and draw the assembly and workpiece picutures.In this graduation project,we mainly design the blanking drawing die, the punching die and flanging die.
Key words: drawing die； blanking drawing compound die； [版权所有：http://think58.com]
