The structure of quenching machine tool for Medium frequency quenching heat treatment equipment. The quenching machine for medium frequency heat treatment and tempering equipment is composed of bed, V bracket, movable rod, reliable sliding table, quenching transformer inductor group, capacitor and quenching slot. The mechanical action is controlled by hydraulic pressure, and the V-shaped bracket holds the workpiece up and down in place, and then coordinates the action by the moving rod. The two reliable camshafts on the sliding table move horizontally to enter or send the camshaft into or out of the sensor. The left spindle box of the machine tool is driven by hydraulic motor to rotate the camshaft. The speed can be adjusted stepless in a certain range. There is a copper plate grounding ring on the left side of the inductor. If the camshaft is not clamped reliably, the ground ring will be touched first when moving horizontally, generating a signal and stopping the action.
Quenching transformer is a variable turn ratio intermediate frequency transformer, the primary stage is 10 ~ 22 turns, divided into 13 grades, the secondary is 6 turns. The sensors are in series in multiple circles, and nine sensors are located on a center line, eight of which are heated cams. The sensor is double-turn, the gap between the cam tip and the inner diameter of the effective ring is 4 ~ 5 mm, and the sensor base has elliptical holes, so that the sensor can be adjusted relative to the axial position of the cam. The camshaft sensor adopts series, which avoids the disadvantages of short intermediate conductive path and long conductive path at two ends when multiple sensors are connected in parallel. When the series inductor method is used, if the temperature of the intermediate cam is on the high side, it can also be adjusted by increasing the gap. Capacitor bank configuration, using three bottles of 300kvar electric thermoelectric container.
A quenching tank and a conveying chain. Quenching tank capacity 1. 5 m3, polymer quenching liquid, Ucon A or 251, with a mass fraction of 10% and a temperature of 3 to 50 C. And the quenching liquid tank is provided with a 6kW tubular electric heater for regulating the temperature of the quenching liquid. And a heat exchanger and a water pump are arranged beside the quenching tank, and the quenching liquid with increased temperature is sent to the heat exchanger, and the water in the heat exchanger is subjected to heat exchange and temperature reduction. The control of the temperature and flow of the system is the same as the general quenching liquid cooling system and is not described in detail. The quenching tank is provided with an inclined conveying chain, and the hardened camshaft is lifted from the bottom to the next working procedure.
