如图2和图6所示，所述外压片70用以对所述待整形轮毂101外壁进行整形。所述外压片70具有多个。所述外压片70的数量与所述内撑片60的数量相匹配；即，每一个外压片70对应于一个所述内撑片60。每一个所述外压片70与其相对的内撑片60正对设置。所述第一驱动机构50驱动所述内撑片60运动、所述第二驱动机构80驱动所述外压片70运动，以使所述内撑片60与外压片70之间相互靠拢、压合、紧贴于所述待整形轮毂101的内壁和外壁，并通过所述内撑片60的第一弧形面61、外压片70同时对所述待整形轮毂101产生压力，从而使经整形后的所述待整形轮毂101能够形成标准轮毂的轮廓线，从而实现所述待整形轮毂101的整形。

优选地，所述第二凸起72以矩形阵列的方式设于所述第二弧形面71上。每一行所述第二凸起72与所述第一弧形面61上的每一行所述第一凸起62呈交错设置。从而使得所述第二凸起72抵持于所述第一弧形面61上的同时，所述第一凸起62也能够抵持于所述第二弧形面71上。因此，当所述内撑片60和所述外压片70夹持所述待整形轮毂101时，所述第一凸起62抵于所述待整形轮 毂101的内壁，所述第二凸起72抵于所述待整形轮毂的外壁。进而，通过交错排列的形式起到良好的夹持作用、以及提高整形效果。
如图9至图11所示，在另一实施例中，所述第二凸起72为齿状凸起()。在这里，所述外压片70也被称作齿状外压片。所述齿状凸起沿所述第二弧形面71的圆周方向排列。每一列所述第二凸起72均与每一列所述第一凸起交错设置。从而使得齿状凸起能够抵靠于所述第一弧形面61上的同时，所述第一凸起62也能够抵持于所述第二弧形面71上。因此，当所述内撑片60和所述外压片70夹持待整形轮毂101时，所述第一凸起62抵于所述待整形轮毂101的内壁，所述第二凸起72抵于所述待整形轮毂的外壁。进而，通过交错排列的形式起到良好的夹持作用，以及提高整形效果。
