【摘要】：针对5A06铝合金复杂盒型件,利用有限元分析软件Deform,确定了先预成形后终成形的等温锻造成形工艺方案。并通过逆向补偿方法设计了预成形及终成形模具。在20 MN锻压机上,先将铝合金板材预锻成预制坯,然后再等温终锻。等温锻造工艺中,模具温度为(450±10)℃,5A06铝合金预制坯温度为(465±10)℃,成形时最大挤压力为14000 k N。等温锻造试验表明;Deform有限元分析对等温锻造成形工艺研究具有较强的指导意义,采用先预成形后终锻成形工艺能大大提高锻件成形质量;此外,5A06铝合金等温锻造盒型件相较于机械加工盒型件,抗拉强度Rm提高到350 MPa,伸长率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 卤10) 鈩，
