Description

Quenching machine tool

Technical Field

The utility model relates to the technical field of quenching, in particular to a quenching machine tool.

Background

The problem of quenching distortion of steel workpieces during heat treatment is one of the difficulties which plague workers in the domestic and foreign industries, and especially, irregular deformation such as warping, elliptical distortion and the like of parts caused by the combined action of tissue stress and thermal stress in the heat treatment process of gear rings and circular ring parts brings great difficulty to the manufacture of parts with high precision requirements.

The existing methods for controlling the distortion of the gear ring mainly comprise the following methods:

1) the machining allowance is increased, the method not only directly increases the production cost, but also needs subsequent high-precision machining equipment to ensure the machining precision, and the cost is higher;

2) the method is characterized in that a certain pressure is applied to the workpiece to correct the distortion part of the workpiece after heat treatment quenching distortion, and the method is used for improving the distortion workpiece to a certain extent, but is very difficult to control the distortion within a small range;

3) a pressure quenching method for expanding mandrel is characterized by that the expansion mandrel is composed of upper pressure cylinder, upper pressure cone head, expansion slide block and platform, and when it is used for pressure quenching, the upper pressure cylinder is combined with the taper of expansion slide block by means of upper pressure cone head to push expansion slide block to open and contact with the inner wall of ring gear or ring to prevent deformation, but the expansion slide block is expanded by means of contact of conical surface, and the slide block can not be completely contacted with inner wall of ring gear or ring, so that the contacted position can be controlled to prevent deformation, and the non-contacted position still has deformation, and at the same time the non-uniformity of conical surface contact can make the expansion force of every expansion block be different, so that it can make the deformation-preventing control of ring gear or ring be non-uniform.

Therefore, a quench machining tool is needed to solve the above technical problems.
