High frequency quenching machine tool exclusion method

①If the primary breakdown, it can be dealt with by the inter-turn short-circuit method.

②If there is a secondary fault, the secondary repair welding leak can be removed, and then painted with red paint. Example 7 The sensor and the workpiece collide. The fault occurs mostly in the mechanical system, especially the rotary heating and quenching mechanism.

Repareer de positioneerinrichting of ontwerp een circuit om te voorkomen dat de sensor in botsing komt met het werkstuk, zodat het de volgende functies heeft:

①Collision before heating, can not send excitation, and can not make the intermediate frequency generator generate voltage.

②Collision during heating, stop the excitation immediately and cut off the intermediate frequency voltage.
