Abstract

The invention relates to the technical field of quenching machine tools, and discloses an induction quenching machine tool with a double-frequency heating power source. The induction quenching machinetool comprises a workbox. A first motor is fixedly mounted on the top of the side face of the workbox, a fixing box is arranged on the top of an inner cavity of the workbox, and an output shaft of the first motor is fixedly sleeved with a lead screw located in the fixing box. According to the induction quenching machine tool with the double-frequency heating power source, two sets of draught fansare started, smoke dust generated when a workpiece is heated and quenched is absorbed through an air flue, the smoke dust generated during quenching is purified through a smoke dust purification device connected with air outflow pipes of the two sets of draught fans, meanwhile, one set of draught fan can be driven to extract cold air from the external environment, the cold air is conveyed into the workbox through the air flue, the other set of draught fan is used for extracting heat generated in the workbox in the heating and quenching processes, thus, the workbox is cooled, the situation that operation of equipment is affected as the working temperature in the workbox is too high is avoided, and the service life of the equipment is prolonged.

Description

technical field

[0001] The invention relates to the technical field of quenching machine tools, in particular to an induction hardening machine tool equipped with a dual-frequency heating power supply. Background technique

[0002] Quenching is to heat the steel above the critical temperature, hold it for a certain period of time, and then cool it at a rate greater than the critical cooling rate, so as to obtain an unbalanced structure mainly composed of martensite (and also obtain bainite or maintain single-phase austenite according to needs). ) heat treatment process, quenching is the most widely used process in steel heat treatment process, and induction hardening is to use electromagnetic induction to generate eddy current in the workpiece to heat the workpiece.

[0003] However, the existing machine tools for quenching cylindrical workpieces need to manually place the workpieces at the position of the induction coil for quenching treatment, which is time-consuming and l...
