Device and method for high-frequency induction heating and liquid spray quenching

Abstract

The invention provides a high-frequency induction heating and spray quenching device. The high-frequency induction heating and spray quenching device comprises a workbench, a loading and unloading mechanism for loading and unloading workpieces from a feeding hopper, an inductor assembly for heating and quenching, a heat monitoring assembly for monitoring heating capacity, a servo sliding table for entering and retreating from the inductor assembly and a falling material distribution mechanism. The workbench comprises a platen. The loading and unloading mechanism, the inductor assembly and the servo sliding table are sequentially arranged on the platen. The heat monitoring assembly is arranged in the inductor assembly and corresponds to the workpieces. The falling material distribution mechanism is arranged on the discharge side of a heating and quenching mechanism. The invention further provides a high-frequency induction heating and spray quenching method adopting the high-frequency induction heating and spray quenching device. The manners of single-end magnetic suction rotary heating and quenching, servo positioning, heating capacity monitoring, falling material distribution mechanism and the like are adopted; the device and the method have the beneficial effects of being short in loading and unloading period, high in positioning accuracy and capable of achieving automatic distribution; and therefore quality and efficiency are improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of high-frequency induction heating and liquid spray quenching, in particular to a fully automatic high-frequency induction heating and liquid spray quenching device and method for small shaft workpieces. Background technique [0002] Induction heating surface quenching is a quenching method that uses the principle of electromagnetic induction to cut the magnetic field lines of the parts in the alternating magnetic field, generate induced current on the surface, and according to the skin effect of alternating current, quickly heat the surface of the parts in the form of eddy current, and then quench them rapidly. It occupies an important position in the field of heat treatment, and this technology has been widely used in our country. Induction heating equipment, that is, equipment for induction heating of workpieces for surface hardening. [0003] The existing high-frequency induction heating and liquid spr...
