【摘要】：針對5A06鋁合金復(fù)雜盒型件,利用有限元分析軟件Deform,確定了先預(yù)成形后終成形的等溫鍛造成形工藝方案。并通過逆向補償方法設(shè)計了預(yù)成形及終成形模具。在20 MN鍛壓機上,先將鋁合金板材預(yù)鍛成預(yù)制坯,然后再等溫終鍛。等溫鍛造工藝中,模具溫度為(450±10)℃,5A06鋁合金預(yù)制坯溫度為(465±10)℃,成形時最大擠壓力為14000 k N。等溫鍛造試驗表明;Deform有限元分析對等溫鍛造成形工藝研究具有較強的指導(dǎo)意義,采用先預(yù)成形后終鍛成形工藝能大大提高鍛件成形質(zhì)量;此外,5A06鋁合金等溫鍛造盒型件相較于機械加工盒型件,抗拉強度Rm提高到350 MPa,伸長率A提高到25%。
[Abstract]:Aiming at the complex box of 5A06 aluminum alloy, the Isothermal forging process scheme of pre-forming and final forming is determined by using the finite element analysis software Deform,. The preforming and final forming dies are designed by reverse compensation method. On the 20 MN forging press, the aluminum alloy sheet is preforged into prefabricated billet, and then the aluminum alloy sheet is finally forged at constant temperature. In the Isothermal forging process, the die temperature is (450 鹵10) 鈩，
