Induction heater made for CPF Plzeň company, is used for induction heating of rod ends with circular cross-section up to forging temperature. It consists of input mechanisms, heater box, inductor, frequency converter and three-phase transformer.
Induction heater is designed in such a way that up to three rod ends can be heated at one time. The operator puts the rods on conveyers manually (rods of smaller weight) or by a manipulator. After pushing the button the individual conveyers (independently on each other) move the rods into the inductor to a preset length of insertion. After the required temperature is reached the indicator above the corresponding coil lights up and the conveyer pushes the rod with its heated end out of the inductor to be moved on for folloving processing. The heater is controlled by Programmable Logic Controller (PLC) made in Siemens. The temperature of each heated rod end is measured by a non-contact temperature gauge UPF IV-G. The induction heater is operated from the control box with buttons and the communication panel. Heating parameters (required temperature, output, etc.) are set on the communication panel. All failures of the heater are displayed in text on this panel, including the instructions for troubleshooting.
