为了防止轻质结构部件的孔的反向挤压中的卡住，利用具有内部通道的冲头的挤压方法用于使用伺服压力机对纯钛坯料进行成形，该内部通道用于向冲头鼻部供应液体润滑剂。在伺服压力机上，冲头以脉冲和步进模式相结合的方式被推入坯料中。足够量的液体润滑剂脉动地供给到孔底部形成的空腔。通过对成形孔和冲头的表面观察来确定适当的冲头冲头运动和防止咬合的成形极限。
To prevent seizure in backward extrusion of holes for lightweight structural components, an extrusion method utilizing a punch having an internal channel for supplying liquid lubricant to the punch nose was applied to forming of pure titanium billet using a servo press. On the servo press, the punch was pushed into the billet in a manner combining pulsed and stepwise modes. The sufficient amount of the liquid lubricant was pulsating supplied to the cavity formed at the bottom of the hole. Appropriate punch ram motion and forming limit for preventing seizure are determined from the surface observation of the formed hole and the punch.
