摘 要
本次的模具設(shè)計(jì)為離合器殼體落料、首次拉深復(fù)合模設(shè)計(jì)。離合器殼體才用的材料是20號鋼，厚度3mm，該材料強(qiáng)度低，韌性、塑性和焊接性較好，用途非常廣泛。適用于制造汽車、拖拉機(jī)及一般機(jī)械制造業(yè)中建造部分零件。如汽車上的手剎蹄片、杠桿軸、傳動被動齒輪及拖拉機(jī)上的凸輪軸、懸掛均衡器軸、離合器殼體等。
首先對零件進(jìn)行了工藝性分析，確定沖壓所需的如落料、拉深，整形等一系列工序。其次經(jīng)過計(jì)算分析確定工藝方案完成該模具的排樣設(shè)計(jì)，凸、凹模工作部分的設(shè)計(jì)計(jì)算，還有模具結(jié)構(gòu)和工藝零件設(shè)計(jì)，選擇合適的模具材料和合理的加工工藝。在設(shè)計(jì)過程中，還利用CAD繪制了一套模具裝配圖和零件圖。

ABSTRACT
The mold design for the clutch housing blanking, drawing the first time, compound die design. Clutch housing material is used only 20 steel, the thickness of 3mm, the low material strength, toughness, ductility and good weldability, uses very extensive. For the manufacture of automobiles, tractors and general construction machinery manufacturing industry in some parts. If the car's hand brake shoe, lever shaft, transmission gears and tractor passive camshafts, suspension equalizer shaft, clutch housing and so on.
First of all parts of the process of analysis, to determine if the required blanking press, drawing, shaping and a series of processes. Second, after completion of the program calculation process to determine the layout of the mold design, convex and concave parts of the mold design and calculation work, as well as part design mold structure and process, select the appropriate mold material and reasonable process. In the design process, also used CAD drawing die assembly and part drawings
Key words Clutch housing；Blanking；Tensile；Compound Die；Design
