Embodiment Construction

[0027] The present invention is described in further detail below.

[0028] A heat treatment deformation control method for a special-shaped aluminum alloy cabin according to the present invention, the method includes the following two parts: 1) supporting design tooling, and changing the furnace loading method.

[0029] The tooling is a cylindrical long rod, and both end faces are sloped, that is, the angle between the end face and the cylindrical axis is not 90 degrees, and the angles between the two slopes and the cylindrical axis are approximately positive 45 degrees and negative 45 degrees. During the solution treatment process of the cabin section, the tooling is horizontal (the inclined plane is inclined upward), the cabin section is above the tooling, and the inwardly concave surface of the cabin section is at the lower part, and the two inclined planes are simultaneously with the inwardly concave surface of the cabin end (the direction on both sides of the axial direct...

Abstract

The invention discloses a special-shaped aluminum alloy cabin section heat treatment deformation control method and belongs to the technical field of heat treatment. The method is used for reducing the special-shaped aluminum alloy cabin section heat treatment deformation amount, and the condition that subsequent machining is directly influenced by deformation of a workpiece is avoided. The methodcomprises the following steps: 1) performing tool design, and determining a charging manner; and 2) performing the heat treatment process. The placement manner of parts is changed, and the design tool is matched, so that the deformation of the parts can be greatly reduced. According to the technology, heat treatment deformation of the parts can be reduced, and deformation produced in a previous process of the parts can be corrected according to requirements.

Description

technical field [0001] The invention belongs to the technical field of heat treatment and relates to a deformation control method for the heat treatment of an aluminum alloy cabin. Background technique [0002] The heat treatment process of aluminum alloy can improve the properties of the material, and the side effect of material deformation will occur during the heat treatment process, and this deformation is inevitable. The deformation of the workpiece will directly affect the subsequent machining. Excessive deformation will bring unexpected troubles to the subsequent machining. Therefore, it is necessary to try to reduce the heat treatment deformation during heat treatment. The heat treatment deformation control method in the prior art is only applicable to specific structural parts. [0003] There are various causes of shape distortion in heat treatment. The release of residual stress during the heating process, the thermal stress, tissue stress and the self-weight of ...
