摘要
针对目前穿孔顶头形状研究所存在的问题,在实验室内就提高一次穿孔毛管的壁厚均匀性及降低能耗进行了系统的试验研究,初步研制成功一种新型的平头对心顶头。
In view of the problems encountered with plug configuration, experimental investigation were made systematically on improvement of wall-thickness uniformity and decrease in energy consumption during shell piercing, and a new plain-head centering plug was preliminarily obtained.
