摘 要
本文是對(duì)拉深件進(jìn)行工藝分析及模具設(shè)計(jì)。該工件是一個(gè)圓筒形拉深件，另外該工件的底部帶有通孔，需進(jìn)行沖孔翻邊，雖然形狀不太復(fù)雜但肯定不能一次成形。通過(guò)對(duì)零件各部分進(jìn)行計(jì)算分析后才能最終確定加工工序。工件整個(gè)成形過(guò)程所涉及的工序有：落料、拉深、沖孔、翻邊等四步。通過(guò)計(jì)算分析得翻邊能一次成形，所以不需進(jìn)行預(yù)拉深，而計(jì)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(fù)合，沖孔、翻邊復(fù)合。在確定工藝方案的基礎(chǔ)上對(duì)主要模具進(jìn)行設(shè)計(jì)，分析工件成型過(guò)程，設(shè)計(jì)模具的結(jié)構(gòu)并畫(huà)出模具裝配圖及零件圖。在本次設(shè)計(jì)中主要對(duì)落料拉深復(fù)合模以及沖孔、翻邊模進(jìn)行設(shè)計(jì)。
關(guān)鍵詞：拉深；落料拉深復(fù)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；
