Adjustable quenching and heating device for tempering production line equipment

Abstract

The invention provides an adjustable quenching and heating device for tempering production line equipment. The adjustable quenching and heating device comprises a base, a protruding block and a cooling pipe. A threaded plate is axially connected into the base. Three sliding supports are evenly distributed on and sliding connected with the top of the base. A high-frequency heating pipe is fixedly connected with the top of each sliding support. A cooling pipe is fixedly connected with the inner lower side of the base. A motor is fixedly connected with the right end face of the base. By changingthe sizes of the inscribed circles of the three high-frequency heating pipes and performing heating through the high-frequency heating pipes with the similar inscribed circles, the aim of hanging thediameter of quenched parts is realized, the adaptability and production efficiency of the quenching equipment are improved, the quenching work of a step shaft can be completed at a time, the quenchingprocess is reduced, productivity is improved, and production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of heat treatment machinery, and more specifically relates to an adjustable quenching heating device used in quenching and tempering production line equipment. Background technique [0002] Quenching refers to a heat treatment method that heats the metal surface to a certain temperature and then cools it rapidly to form martensitic crystals on the metal surface to increase the surface hardness of the metal. Generally, the position of the part that needs to be quenched is the journal that needs to be matched. The existing The quenching device generally uses a power device to rotate the parts, and the journal of the parts is heated by a high-frequency heating tube, and then the coolant is sprayed for rapid cooling. [0003] For example, application number: CN201310220351.9 A rotating shaft quenching device, including a quenching induction coil and a quenching part, the quenching induction coil is suspended abo...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an adjustable quenching heating device for quenching and tempering production line equipment to solve the problem that the existing high-frequency heating tube generally adopts a spiral tubular structure based on the consideration of heating efficiency, and its diameter cannot be changed, resulting in a heating The tube can only heat parts of one diameter, and the adaptability is not good. At the same time, when quenching the stepped shaft, it needs to be quenched twice or even multiple times for different journals, which seriously affects the production efficiency.
