Special camshaft high-frequency quenching device

Abstract

The invention discloses a special camshaft high-frequency quenching device, and relates to the technical field of heat treatment equipment. The problems that during quenching machining of an existing camshaft, an existing induction coil is provided with an opening, during heating, opening heating unevenness, burning, cracking, hardness unevenness, quenching layer depth unevenness and the like are prone to happening, cracking is prone to happening, and the product quality is influenced are solved. The special camshaft high-frequency quenching device comprises an installing base, wherein a set of camshaft rotation drive pieces are fixedly connected to the lower portion of the front end face of the installing base; a set of lifting drive pieces are fixedly connected to the top of the installing base; a set of lifting sliding bases are in sliding connection to the left side of the installing base; and a set of slippage drive pieces are fixedly connected to the rear end faces of the lifting sliding bases. The special camshaft high-frequency quenching device solves the problems of burning, cracking, hardness unevenness, quenching layer depth unevenness and the like existing in the heat treatment process, the quality of the camshaft is improved, oxidation residues on the surface of a part are cleaned away, and the machining quality of the part is improved.

Description

Technical field [0001] The present invention relates to the technical field of heat treatment equipment, in particular a special cam axle high frequency quenching equipment. Background technique [0002] The quenching is the temperature of the steel to the critical temperature AC3 (sub-zone) or AC1 (hyperzal steel) or the above time, allowing it to all or part of the austenite, and then faster than the critical cooling speed Cold to MS below (or near MS is still waiting for the heat treatment process of martensite (or Bihysite) transition, in order to greatly improve the rigidity, hardness, wear resistance, fatigue strength, and toughness of the steel, so in the camshaft processing process The camshaft is often required to be quenched. [0003] For example, the present invention is an intelligent automatic high-frequency quenching machine including: an automatic upper conveyor belt, a substation positioning mechanism, a feed robot, and a spacing adjustment positioning mechanism, ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a special high-frequency quenching equipment for camshafts to solve the problem that the existing camshafts generally pass through the coils during quenching in the above background technology. High-frequency heating is carried out by induction. There is an opening in the existing induction coil, which is prone to problems such as uneven heating of the opening, burns, cracks, uneven hardness, and uneven depth of quenching layer during heating, which may easily lead to cracks and affect product quality.
