筒体卷圆是第九车间压力容器生产制造过程中的重要环节之一。筒体卷圆是在三辊卷板机上进行,因三辊卷板机不能弯卷钢板的全部长度,钢板两端有一定的残留直边段,所以需对残留直边进行预压弧处理。通常所采用的方法是用液压机先对钢板两端进行压头,然后再进行卷圆。但增加了周转、提高了劳动强度。通过对三辊卷板机工作原理的研究,在3m3六氟化铀容器生产过程中试验了一种在三辊卷板机上不需要预先对钢板两端进行预弯而使筒体成型的新工艺。本文详细介绍了新工艺的原理及工艺过程,计算出相关数据。并对试验筒体进行测量,与GB150《压力容器》标准要求进行对比,证明采用此方法卷圆的筒体完全符合标准要求。使车间筒体卷圆工序效率得到提高,并降低了劳动强度,减少了周转、工序间的等待时间。
Cylinder winding is the ninth workshop pressure vessel manufacturing process one of the important aspects. Cylinder winding is carried out in the three-roll coiling machine, because the three-roll coiling machine can not bend the full length of the steel plate, the steel plate at both ends of a certain residual straight edge, so the need for residual straight edge pre-arc treatment. The commonly used method is to press the two ends of the steel plate with a hydraulic press first, and then rewind. But increased turnover, improve labor intensity. Through the study of the working principle of the three-roll plate bending machine, a new process for forming the cylinder on the three-roll plate bending machine without pre-bending the two ends of the steel plate was tested in the production process of the 3m3 uranium hexafluoride container . This article describes in detail the principle of the new process and process, calculate the relevant data. The test cylinder is measured and compared with the GB150 “pressure vessel” standard requirements. It is proved that the cylinder rolled in this way fully meets the standard requirements. The process of winding the workshop cylinder is improved, the labor intensity is reduced, the turnover time and the waiting time between the processes are reduced.
