The upper apron board device disclosed by the invention comprises an apron board main body, wherein the apron board main body comprises a superplastic unit prepared by a superplastic forming process and a profile unit prepared by a profile extrusion process. The superplastic unit adopts a superplastic forming process, so that the internal stress of the aluminum alloy base material can be eliminated, the superplastic unit keeps good mechanical performance, and the structural strength of the upper apron board device is improved. The superplastic unit and the profile unit are connected through friction stir welding, the welding strength of friction stir welding is high, welding deformation is small, the connecting strength between the superplastic unit and the profile unit is improved, and the appearance quality of the upper apron board device is guaranteed. The machining method of the upper apron board device is used for preparing the upper apron board device and comprises the main body preparation step and the apron board welding step.

    本发明公开的上裙板装置包括裙板主体,裙板主体包括通过超塑成型工艺制备的超塑单元和通过型材挤压工艺制备的型材单元。超塑单元由于使用超塑成型工艺,因此可以消除铝合金基材的内部应力,使超塑单元保持良好的机械性能,提高上裙板装置的结构强度。且超塑单元和型材单元通过搅拌摩擦焊连接,搅拌摩擦焊的焊接强度高,焊接变形小,提高了超塑单元和型材单元之间的连接强度,并保证了上裙板装置的外观质量。本发明提供的上裙板装置的加工方法,用于制备上述的上裙板装置,包括主体准备步骤和裙板焊接步骤。
