Abstract

The invention discloses quenching equipment for a slender shaft component. The quenching equipment comprises a bed body and a water-cooling machine arranged on one side of the bed body, wherein a high-frequency machine is fixed below the bed body, a water tank and a movable guide rails are arranged on the top surface of the bed body, a high-frequency head is arranged on the movable guide rail, andthe top end of the high-frequency head is connected with two free ends of an induction heating coil; the induction heating coil stretches into the water tank; a fixed mechanism is arranged in the water tank; the high-frequency head is connected with a servo motor and the high-frequency machine respectively; the water-cooling machine is used for conveying cooling water to the high-frequency head and the high-frequency machine; and a PLC is electrically connected with the servo motor, the high-frequency machine and the water-cooling machine. The quenching equipment has the beneficial effects that accurate positioning is realized by virtue of a fixed tool, and the quenching equipment is convenient to take and place; one end of the shaft component is heated by a certain length by virtue of ahigh-frequency induction principle; an equipment control system is constructed by virtue of the PLC; a circulating water-cooling type workpiece and a high-frequency induction heating coil are adopted;and a transparent protecting cover is additionally arranged, so that the influence caused by the convection of a small amount of air to the workpiece is prevented.

Description

technical field [0001] The invention belongs to a high-frequency heating treatment device, in particular to a quenching device for slender shaft parts. Background technique [0002] The heating method of heat treatment is determined according to the material, size and other conditions of the part, such as laser heating, gas flame heating, etc. The above-mentioned heating method has the problems of stable and unstable heating process and consistent heating time, and there may be fluctuations in the hardness of the slender shaft after treatment. [0003] The high-frequency induction heating technology is to place a metal workpiece in the induction coil. The AC current passing through the two ends of the induction coil will generate a corresponding induction current in the heated object. When the resistance becomes larger, the corresponding conductor will generate more heat. High-frequency induction heating technology has the characteristics of fast heating speed, high thermal...
