吊环等类型的弯曲件一般在专用工其的配合下,在锤上弯曲和胎板上弯曲而成的。由于我车间无这种专用工具,对大吊环的弯曲,采用了下列工艺,效果较好,现介绍如下: 先将毛坯锻好,然后装入室式炉加热至1100℃左右(不要露在炉外边),温度要求均匀。在一个大平面的钢板上焊接一个φ560的芯铁,在铁板的另一端两角处焊上圆环,每个圆环上挂一个滑车,再准备两根一样长的钢丝绳,一端挂在天车钩子上,另一端和两根一样长的链条连接住,弯曲时把链条
Rings and other types of bending parts generally in the special work with the cooperation of the bending on the hammer and the bending of the tire board. Because of my workshop without such special tools, the bending of the large rings, using the following process, the effect is better, are as follows: First blank forging, and then loaded into the chamber furnace heated to about 1100 ℃ (Do not exposed in the furnace Outside), the temperature required uniform. Welding a φ560 core iron on a large flat steel plate, welding rings on the two corners of the iron plate, hanging a pulley on each ring, preparing two additional long wire ropes and hanging one end on a day Car hook, the other end and two as long as the chain connected to live, bending the chain
