我厂过去加工图1所示的异形弹簧,基本都是手工生产,劳动强度大,产量低,而且质量不稳定。为此,我们经过革新,将该弹簧加工过程中劳动强度最大,难度最高的写道工序——绕制工序,实现了机械化操作,使生产效率提高了四倍,产品质量也得到了保证。绕簧机的主要结构如图2,气缸直径120毫米,活塞最大行程315毫米,齿杆有效行程300毫米。操纵转阀Ⅰ在“开”、转阀Ⅱ在“后退”位置时,P_1进气,P_2排气,待系统复位后,在弹簧心轴25上,装上待加工的弹簧钢丝,插入带动销24,操纵转阀Ⅱ至“前
I plant the past processing of deformed springs shown in Figure 1, are basically hand-made, labor-intensive, low output, and the quality is unstable. To this end, we have been innovative, the spring of the most labor-intensive process, the most difficult write process - winding process, to achieve a mechanized operation, the production efficiency increased four-fold, product quality has also been guaranteed. The main structure around the spring machine shown in Figure 2, the cylinder diameter of 120 mm, 315 mm maximum stroke piston, rack effective stroke 300 mm. Operation of rotary valve Ⅰ in the “open”, rotary valve Ⅱ in the “back” position, P_1 intake, P_2 exhaust, to be reset system, the spring mandrel 25, to be processed with spring steel wire, insert the drive pin 24, operating the rotary valve Ⅱ to "before
