液压成形时，将预制的管坯零件置于成形模具中，在要加工波纹的管坯两端进行密封。在密封管段通入高压乳化液，达到管坯的屈服强度时，管坯在相邻的两片模瓣间向外胀起初波。初波达到设计弧度80吨单柱液压机，停止泵入高压乳化液单柱液压机。相邻两片模瓣挤压初波至规定波厚，加压到整压力，管壁贴合模具凹腔定形。成形系统卸压后，打开模具，退回冲头，得到液压成形的波纹管零件。

为了防止压力油从泵体和泵盖间泄露到泵外，并减小压紧螺钉的拉力，在泵体两侧的端面上开有油封卸荷槽16，使渗入泵体和泵盖间的压力油引入吸油腔拉伸液压机。在泵盖和从动轴上的小孔，其作用将泄露到轴承端部的压力油也引到泵的吸油腔去，防止油液外溢，同时也润滑了滚针轴承。
