摘　　要：为解决挤压铝型材局部变形整形困难的问题,提出高频精密锻造加工的整形方法。针对某槽型铝挤压型材工件,建立有限元模型,采用分段步进式锻造整形,通过过量加载调整工件回弹引起的变形,并模拟锻造整形过程,对比分析结果,得到了过载量参数对整形效果的影响规律。通过试验验证,证实了高频精密锻造加工可对挤压铝型材的局部变形进行有效整形。In order to shaping the local deformation of extruded aluminum profiles,a new shaping method for high-frequency precision forging was provided.The finite element analysis which was applied as the step-feeding method to forging and shaping had been performed on the slot aluminum extrusion profile.During the process of forging simulation,it changed the metal rebound deformation according overloading.By comparing the analysis results,it obtained the influence law of the overload parameter on the shaping effect.Through the test verification,it is confirmed that the high-frequency precision forging process can effectively shape the local deformation of the extruded aluminum profile.
