Whole quenching device of circular track

Abstract

The invention provides a whole quenching device of a circular track. The device is suitable for quenching of a circular track with an outer circle and can realize whole heating, whole liquid spray and completion of the quenching process. By adopting the device, the quenching quality is stable, the soft belt is avoided and the life of the track is greatly prolonged. The invention adopts the following technical scheme: the device comprises a liquid sprayer and a track sensor, wherein the liquid sprayer is a circular ring body; the circular ring body is provided with a hollow cavity inside; the liquid sprayer is connected with liquid inlet joints and connecting screw rods; the track sensor is installed in the inner circle cavity of the liquid sprayer; the inner circle of the liquid sprayer is provided with liquid spray holes on the whole circumference; the track sensor comprises at least five track sensing circles uniformly arranged on the circumference; the track sensing circles are installed on a fixed block and are communicated with each other; the fixed block is fixed on the liquid sprayer by a bolt; one end of the fixed block is provided with a liquid inlet and the other end of the fixed block is provided with a liquid outlet; and common pole plates are installed on the fixed block and are connected with the track sensing circles.

Description

technical field [0001] The invention relates to an overall quenching device for a ring track, which is suitable for quenching a ring track with an outer ring track. Background technique [0002] The shape of the slewing support track is a thin ring, and the quenching part is a hemispherical or V-shaped groove around the ring. In traditional quenching, only one orbital induction coil is installed to perform continuous scanning quenching. The quenching time is as long as tens of minutes. The quenching time is long, and the inconsistent heating deformation causes the quenching layer depth and hardness to be uneven, and there is a soft band. Contents of the invention [0003] In order to achieve no soft zone after quenching of the annular track similar to the rotary support track, uniform layer depth and hardness after quenching, and reduce quenching time, the present invention proposes an integral quenching device for the annular track. [0004] For this reason, the technica...

AI Technical Summary

Problems solved by technology

In the traditional quenching, only one track induction coil is installed, and continuous scanning quenching is performed. The quenching time is as long as tens of minutes, the quenching time is long, and the heating deformation is inconsistent, which causes the depth of the quenching layer and uneven hardness, and there is a soft zone.
