摘 要
本文是對拉深件進行工藝分析及模具設(shè)計。該工件是一個圓筒形拉深件，另外該工件的底部帶有通孔，需進行沖孔翻邊，雖然形狀不太復雜但肯定不能一次成形。通過對零件各部分進行計算分析后才能最終確定加工工序。工件整個成形過程所涉及的工序有：落料、拉深、沖孔、翻邊等四步。通過計算分析得翻邊能一次成形，所以不需進行預拉深，而計算可知拉深可一次成形，所以確定最終工藝方案為：落料與拉深復合，沖孔、翻邊復合。在確定工藝方案的基礎(chǔ)上對主要模具進行設(shè)計，分析工件成型過程，設(shè)計模具的結(jié)構(gòu)并畫出模具裝配圖及零件圖。在本次設(shè)計中主要對落料拉深復合模以及沖孔、翻邊模進行設(shè)計。
關(guān)鍵詞：拉深；落料拉深復合模；
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；
