Have you seen an induction heating furnace for camshaft quenching?

The quenching method for heating all the quenched surfaces of the camshaft at one time is to heat all the quenched surfaces of the camshaft at the same time, and then immediately move to the quenching position for quenching. Its productivity can reach 200~300 pieces/h. The time for the workpiece to move from the heating position to the quenching position should be as fast as possible, and it depends on the critical cooling rate of the workpiece material. This quenching method is mainly used for cast iron camshafts, especially alloy cast iron, because the critical cooling rate of alloy cast iron is low.

The quenching of the induction heating furnace adopts a horizontal structure, which is composed of a bed, a V-shaped bracket, a movable rod, a sliding table with a top, a quenching transformer inductor group, a capacitor, and a quenching tank. The mechanical action is controlled by hydraulic pressure. The bracket holds the workpiece, ascends and descends into place, and then moves in cooperation with the movable rod; the two centers on the sliding table clamp the camshaft for lateral movement, and the camshaft enters or sends out the sensor; The left headstock is driven by a hydraulic motor to rotate the camshaft, and the speed can be steplessly adjusted within a certain range. There is a copper grounding ring on the left side of the sensor. If the camshaft is not clamped correctly on the top, it will first touch the grounding ring when moving laterally, generating a signal and stopping the action. The sensor is shown in Figure 8-23.
