Abstract:
     The wheel arms of gear blanks with finishing forging temp. of 920-1030 deg.C are champed by the champing apparatus firstly, air cooled to 820-900deg.C, then water quenched. When the gear blanks are cooled to about 300 deg.C in water bath, they are taken out and air cooled to room temp. The machine used in this process is chain driving. On the chain mounted a special champing apparatus, which may clamp the gears and may clamp and loose it automatically. The time of air cooling before quenching depends on the movement speed of the driving mechanism. The characters are simple structure efficiency and low cost.
