The structure and working principle of elbow machine
The main structure of elbow machine: mainframe, hydraulic power pack, operation station, electrical control cabinet, intermediate frequency power source, compensating capacitor, water and cable, intermediate frequency coil frame adjustment, electric reactor.
The working principle of elbow machine: put the raw material cover on the core rod of elbow moulds; cover the medium frequency induction coil on the telos of core rod. The open the cooling water pump and medium frequency power source, heating raw material to about 8000C, then open pushing machine to push the elbow.
Based on the elbow to choose the main pump, the core rod gets the temperature of working to push. The pushing speed is adjustable. The pushing machine stops automatically when it arrives the middle. Close the hydraulic gate, load material on core bar, loose the gate then back to the end. Began to push when the gate arrive the rod diameter.
Attention: the main pushing pump working can be used at the same time, generally use one set. Also it can be used to retreat. The backward pump isn't used at the same time, only to open one set, other is space. The feeding pump is only used when feeding materials. The both ends of pushing machine add switch, the actual journey less than maximum stroke, meaning keeps some space betweeen the both ends of pushing board and actual endpoint, in order to avoid oil cylinder arrives there.
