我厂预应力电杆是用强度为15000公斤/厘米~2以上的高强丝作纵筋的。高强丝用LD-10型镦头器镦头。这种镦头器的夹片使用寿命不长,给操作、维修、配件准备都带来了许多麻烦。镦头的过程是:将高强丝插入镦头器,开启油泵,外缸进油。当油压低于顺序阀开启油压时,顺序阀不开启,内缸不充油,此时内外油缸活塞共同向前运动,随之逐渐调整钢丝在夹片与镦头模之间的距离,使其适合镦头成形所需要的长度。同时,经
Our prestressed pole is made of high-strength wire with a strength of 15000 kg/cm~2 or more. High-strength wire uses LD-10 type steamer head. The long life of clips of this type of head hammer has brought a lot of troubles to operation, maintenance and spare parts preparation. The process of steamed bread is: insert the high-strength wire into the steamer, open the oil pump, and put the oil into the outer tank. When the oil pressure is lower than the sequence valve opening pressure, the sequence valve does not open and the inner cylinder is not filled with oil. At this time, the inner and outer cylinder pistons move forward together, and gradually adjust the distance between the clip and the hammer die. Make it suitable for the required length of the boring head. At the same time, the
