Wind Power Workpiece

Slewing Ring Rolling Elements Raceway Hardening Machine

Slewing Ring Rolling Elements Raceway Hardening Machine

This machine is suitable for slewing ring parts roller continuous scanning heating, which can satisfy ball roller and 3-row roller heating and quenching. During heating, the function that one is preheating while the other is heating can be achieved. The transformers moving around and work-piece rotary are all driven by SIEMENS servo motor. The equipment has the function of automatic alignment by inductor, and in the process of work-piece induction heating, the system compensates automatically all the time, to ensure the space between inductor and work-piece identical. Both the inductor and sprayer adopt hydraulic and electric quick coupler, which is convenient for replacement and adjustment. All device processing parameters can be input through special parameters screen, and can store a plurality of processes. The control system has the process parameter monitoring and recording function, and the product process can be traced back.
