Quenching die and using method

Abstract

The invention discloses a quenching die and a using method. The structure of the quenching die comprises a workpiece, a quenching pipe, a heat conduction connector, an installation hole, a polished surface assembly, a die base, an installation plate, a cooling connector and a conversion mechanism; the bottom of the conversion mechanism is installed in the die base in an embedded mode; the die baseis of a rectangular structure; and the installation plate is arranged at the bottom of the die base. The workpiece is driven by the conversion mechanism to rotate, ascend and descend so as to be matched with the quenching pipe for comprehensive quenching treatment, the cooling mode is that uniform spraying is conducted in an inner cavity of the workpiece through the cooling assembly, leaving of impurities in water due to direct washing with the surface can be prevented, the uniform cooling effect is reserved, automatic rotating, ascending and descending are completed under driving of a liquidrotating mechanism, and the manual procedure steps are omitted.

Description

[0001] This application is a divisional application of a large-size carburizing steel double-row spherical roller bearing outer ring quenching die with an application date of July 19, 2019 and an application number of CN201910656283.8. technical field [0002] The invention relates to the field of molds, in particular to a quenching mold and a use method. Background technique [0003] Double-row self-aligning roller bearing is a type of bearing with self-aligning function. It is not easily limited by the angular error between the shaft and the outer ring of the bearing. It is suitable for installing various types of error-angle shafts or crankshaft equipment. It is used in papermaking machinery, It is widely used in reduction gears and railway vehicles. For double-row spherical roller bearings, most of the materials are made of carburized steel. Generally, after production and molding, the outer ring needs to be quenched by a high-frequency machine, thereby greatly improving ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a quenching mold and its use method to solve the problem that the current quenching mold is to support and fix the double-row self-aligning roller bearings, and then use it with a high-frequency machine. Fixed function, during the heating process, the staff needs to manually complete a series of processing procedures such as lifting, rotating, and smoothing, which cannot ensure the quality of quenching, and the direct cooling of the surface by water flow will easily cause more impurities on the surface of the outer ring, and the surface cannot Stay slick, a problem to be optimized
