轧管机上辊的升降速度直接影响着轧制的间歇时间,加快斜楔速度是减少间歇时间的较好方法。在实际操作中,我们感到轧管机的斜楔机构速度较慢,对此做了如下的改进。1.设备性能:(1)空气压缩机:型号:1—6/7型;功率:52马力;工作压力:7kg/cm~2;排气量;6m~3/分。(2)气缸:直径:200mm;活塞行程:350mm,进排气孔各为1/2″。(3)管路:总风管为2(1″)/4,支总管为3/4′(改后采用1(1″)/2)气管为1/2″(改后为1″)。其管路布置见下图。
The rise and fall speed of the upper roller of the pipe mill directly affects the intermittent rolling time. It is a better way to reduce the intermittent time to speed up the wedge speed. In actual operation, we felt that the wedge mechanism of the rolling mill machine was slower and made the following improvements. 1. Equipment performance: (1) Air compressor: Model: 1-6 / 7 type; Power: 52 horsepower; Working pressure: 7kg / cm ~ 2; Displacement; 6m ~ 3 / min. (2) Cylinder: Diameter: 200mm; Piston stroke: 350mm, Intake and exhaust holes are 1/2 “each. (3) Pipeline: Total air duct is 2 (1” (Change 1 (1 “) / 2) The trachea is 1/2” (changed to 1). The piping layout is shown in the following figure.
