【摘要】：針對汽車變速銷的形狀、尺寸以及材料性能等特點,選定了單工步開式模鍛的成形方法。使用CAE有限元分析軟件Deform-3D對初始工藝方案進行仿真研究,分析了材料成形過程中的熱、力情況,否定了初始工藝方案的可行性。從坯料尺寸、坯料溫度以及模具結構3個方面出發(fā),對成形工藝進行改進,制定了3套改進方案,并通過模擬方法得到較優(yōu)工藝,即:坯料尺寸為Φ17 mm×47.5 mm,坯料溫度為700℃,在凹模上增加Φ60 mm×0.2 mm的飛邊槽以及在凸模前端設置1個Φ12 mm×0.5 mm的凸起。采用改進后的模具及優(yōu)化工藝進行實驗驗證,證明了該工藝的可行性。
[Abstract]:According to the shape, size and material properties of automobile gearpin, the forming method of simplex open die forging was selected.The CAE finite element analysis software Deform-3D is used to simulate the initial process plan. The heat and force in the process of material forming are analyzed and the feasibility of the initial process scheme is denied.Starting from three aspects of blank size, blank temperature and die structure, the forming process was improved, and three sets of improvement schemes were established. The optimum process was obtained by simulation, namely: the blank size was 桅 17 mm 脳 47.5 mm, the blank temperature was 700 鈩，
