一般叶片弹簧的热处理是比较麻烦的,过程繁杂,效率低。苏联工程师赫瓦洛夫建议使用一种内冷却的淬火夹具,对叶片弹簧进行干淬火。这种干淬火法,就是在两个水循环冷却的淬火夹具之间,放上加热到淬火温度的叶片弹簧,然后用夹具把它紧紧地压住。淬火夹具的结构像附图那样。苏联一个工厂曾经用截面120×12和50×8的55C_2弹簧扁钢进行试验。试件加热到880～900℃后,放在淬火夹具内冷却1～5分钟。附表所列的就
The heat treatment of the general leaf spring is more troublesome, the process is complicated and inefficient. Hvarov, a Soviet engineer, recommends using an internally cooled quench jig to dry-quench the leaf springs. This dry quenching method, that is, between two quenching jets cooled by water circulation, placed on the leaf spring heated to quenching temperature, and then use it to clamp it tightly. The structure of the quenching jig is as shown in the attached drawings. A factory in the former Soviet Union used 55C_2 spring steel bars with cross sections of 120 × 12 and 50 × 8 for testing. The specimen is heated to 880 ~ 900 ℃, placed in a quenching fixture cooling 1 to 5 minutes. Schedule listed on the
