本发明公开了一种增量挤压成形的方法，包括以下步骤：增量挤压开放模具结构设计与装配；初始坯料的准备；增量挤压成形。其增量挤压方法是，将坯料放置在芯模的型腔内部，坯料的下端面与垫块的上表面接触，垫块的上表面低于凹模的内腔平面；在凸模挤压压制坯料的过程中，迫使坯料中间部位的金属水平流动穿过芯模的下表面的缩颈变形区域，金属沿着凹模的内壁向上流动，达到增加坯料内腔尺寸和变形量的效果；在凸模向下运动到一定位移后，顶杆向上运动，带动垫块向上压制坯料，迫使坯料底部金属水平流动穿过芯模的下表面的缩颈变形区域，进一步达到增加坯料变形量的效果。本发明可以增加坯料的变形量，解决取料困难、芯模刚性差的问题，实用性强。

本发明涉及一种多凸模分步反向挤压成形方法，采用由内凸模、外凸模组成的多凸模，包括：下料——制坯——分步反向挤压——后续处理，其特征是：所述的分步反向挤压是使用内凸模、外凸模至少一次挤压坯料金属，坯料金属在所述多凸模的作用下产生流动变形，并通过控制内凸模、外凸模的行程，获得底部为实心平底、或凹底、或凸底的空心件。本发明在同一套模具内，可实现平底、凸底、凹底等空心件的成形制造；挤压成形接触面积的减小，降低了挤压成形力，可提高挤压变形量。
