Abstract
The invention discloses a heat-treatment workpiece correction treatment method. The method comprises the specific steps that firstly, heat-treatment workpiece is machined and shaped, and predeformation with the direction opposite to the direction of the heat-treatment deformation is generated in the workpiece machining process; secondly, heat treatment is carried out. Because predeformation machining is conducted on the workpiece before the heat treatment process to deform the workpiece in the direction opposite to the direction of heat-treatment deformation, the deformation direction before heat treatment is opposite to the deformation direction after heat treatment, and two kinds of deformation are mutually offset. The method is convenient to carry out and easily guarantees quality.
Description
Technical field
The present invention relates to a kind of workpiece correction method, particularly a kind of heat treated part correction processing method.
Background technology
In metal heat treatmet, after heat treatment a lot of workpiece deformations are larger, and alignment is wasted time and energy very much.Sometimes the large and deformation of the part deformation had is always the same.Existing aligning method is exactly to carry out alignment according to the distortion particular case after thermal treatment, and the part this aligning method large to deformation comparison usually do not reach requirement, and alignment is more difficult.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of heat treated part correction processing method, this heat treated part correction processing method is simple to operate, easily guarantees workpiece quality.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of heat treated part correction processing method, and concrete steps are as follows:
Step 1: heat treated part machine-shaping, workpiece adds the predeformation produced man-hour with the heat treatment deformation opposite direction;
Step 2: heat-treat.
Before thermal treatment, part is carried out to predeformation processing, make part deformation, towards the Direction distortion of heat treatment deformation opposite direction, before thermal treatment, the latter two deformation direction is contrary like this, cancels each other, and this convenience, easily ensure the quality of products.
As a further improvement on the present invention, also be provided with following steps after thermal treatment:
Step 3: final recalibration just, can be guaranteed the workpiece correction precision like this.
Useful technique effect of the present invention is: the present invention carried out predeformation processing to part before thermal treatment, made part deformation, towards the Direction distortion of heat treatment deformation opposite direction, before thermal treatment, the latter two deformation direction is contrary like this, cancel each other, this convenience, easily ensure the quality of products.
