Abstract

The invention provides an undercarriage part heat treatment distortion control device and method. The undercarriage part heat treatment distortion control device comprises a heat treatment frame, a top adjusting module arranged at the upper end of the heat treatment frame, a supporting base module arranged at the bottom of the heat treatment frame, an anti-expansion control module matched with thesupporting base module and a horizontal adjusting module fixed to the heat treatment frame in a scalloped manner. The top adjusting module and the supporting base module are located in a hollow structure of the heat treatment frame, and the control directions of the top adjusting module and the supporting base module are vertical. The anti-expansion control module and the horizontal adjusting module are located in the hollow structure of the heat treatment frame, and the control directions of the anti-expansion control module and the horizontal adjusting module are horizontal. Compared with the prior art, by means of combined adjustment of the modules, the problem of unstability generated by stress unbalance in the part transferring process is solved, oil input is carried out in an inverted-y manner in the vacuum heat treatment quenching process of parts, it is guaranteed that a barrel is in a vertical state, and quenching oil flowing is convenient.

Description

technical field [0001] The invention relates to the technical field of metal heat treatment processing, in particular to a vacuum quenching heat treatment technology, and further relates to a heat treatment deformation control device and control method for landing gear parts. Background technique [0002] Metal workpiece heat treatment is to put the metal workpiece into the heating device, heat it to a specific temperature for a specific time, and then cool it to change the internal structure of the metal to achieve the purpose of improving the mechanical, physical and chemical properties of the material. During the heat treatment process, the specific volume changes due to the transformation of the structure, resulting in volume expansion. At the same time, the elastic and plastic deformation caused by the uneven wall thickness of the workpiece changes the shape of the part to varying degrees, resulting in heat treatment deformation. Some miscellaneous structural parts with...
