摘要：針對汽車后門外板采用鋁材時，沖壓成形過程中容易產生回彈問題，以某SUV車型鋁后門外板為例，利用AutoForm 軟件對其沖壓全工序進行仿真模擬，通過采用合理的工藝方法和模具結構，減小成形零件的回彈，再進行拉深整體回彈補償，解決了該零件成形回彈的問題。

Abstract: When the rear door outer panel of automobile is made of aluminum plate, springback is easy to occur in the stamping process. Taking a SUV aluminum rear door outer panel as an example, the whole stamping process was simulated by using AutoForm software. The springback of parts will be effectively reduced by adopting reasonable process method and die structure. Then the drawing springback compensation was carried out, which effectively solved the springback problem of the part.
