The working principle of friction welding machine:
The friction welding machine is the commonest equipment which takes advantage of the heat in mutual movement of contact end’s work piece. First of all, when welding the work pieces on the round surface, one of which rotate at speed going around with the spindle, then bringing pressure on the other one and starting to rub, reaching to the set time of the machine, stopping rotating immediately, meanwhile forcing more pressure on the spindle to upset welding. Usually the whole process takes only couple of seconds
According to different products, we have different designs to produce right machine
Distinguished by chuck: mechanical three jaws chuck and hydraulic chuck
The defect of the mechanical chunk is small adjustment range(2-3mm). If the work piece is rough with big difference of size, maybe we can not put it in. Besides, the mechanical chunk is easy to wear and slip, so it’s mainly used in work piece with small difference of size and shorter parts.
Hydraulic chunk: high strength, never slip, never abrade, big adjustment range(20-30mm), wider used.
The hydraulic chunks are divided into single hydraulic cylinder and double hydraulic cylinders. Generally speaking, single hydraulic is valid within 500mm length products, longer needs double hydraulics
