1. The principle of CNC automatic quenching machine:
CNC automatic quenching machine is used to control the depth of quenching accurately by using accurate inductor or induction coil and controllable current voltage and frequency, which is generally used for surface quenching. It is mainly composed of three parts: quenching machine tool, medium frequency power supply (high frequency power supply, superaudio frequency power supply, ultrahigh frequency power supply) and cooling device. The high frequency quenching machine consists of the bed, the upper and lower clamping mechanism, the clamping and rotating mechanism, the quenching transformer and the resonant groove Road, the cooling system, the quenching liquid circulation system and the electric control system, etc.
2. The principle of induction heating quenching machine.
Induction heating quench machine is a power device that converts power frequency 50HZ alternating current to intermediate frequency 300HZ to 1000HZ, and turns the three-phase power frequency alternating current into DC, then turns DC into adjustable intermediate frequency current, and supplies the intermediate frequency alternating current flowing through the capacitance and induction coil, and produces high density in the induction coil. The magnetic lines of force and the metal materials in the induction coil generate large eddy currents in metal materials. Because the principle of medium frequency induction heating is electromagnetic induction, its heat is produced in the work piece itself. The ordinary workers can carry on the continuous work of forging task for ten minutes after working by the medium frequency electric furnace.
