Modular fixture for partial heat treatment of induction heating and using method thereof

Abstract

The invention provides a modular fixture for partial heat treatment of induction heating and a using method thereof. The modular fixture comprises a heat conduction fixture body, a heat insulation fixture body, a press plate and pressing mechanisms; the heat conduction fixture body, through inner steps therein, is assembled with outer steps of the heat insulation fixture body, and is attached to the surfaces of to-be-heat-treated components, and a through hole used for showing the to-be-heated area is formed in the interior of the heat conduction fixture body; and the pressing mechanisms comprise support blocks in hinged connection and pressing blocks, the support blocks support the bottom of the pressing plate, and the pressing blocks press the top surface of the heat insulation fixture body tightly so as to press the to-be-heat-treated components tightly. When in use, the specifications of the heat conduction fixture body and the heat insulation fixture body are selected according to the area size of the to-be-heated area. According to the modular fixture for the partial heat treatment of induction heating and the using method thereof, the accurate control over the heating area and the heating temperature of the repair area of the to-be-heat-treated components can be achieved, the problem of extremely-poor deformation generated in the heating process is solved, the operation is simple, the cost is low, and the universality is good.

Description

Technical field: [0001] The invention belongs to the technical field of local heat treatment after metal parts are repaired, and in particular relates to a modular fixture for induction heating local heat treatment and a use method thereof. Background technique: [0002] In the field of aerospace, for large thin-walled parts that fail due to cracks, corrosion, wear and other damages during service, laser additive repair, argon arc welding, electron beam welding and other processes can be used to achieve rapid repair, which can prolong the service life of parts , to recover economic losses. However, residual stress and performance weakening will inevitably occur in the repaired parts of the parts, which will have an adverse effect on the performance of the workpiece and the stability of use. [0003] Heat treatment can effectively eliminate the residual stress of repaired parts and improve the mechanical properties of parts. However, for large thin-walled parts, the overall...

AI Technical Summary

Problems solved by technology

However, for large thin-walled parts, the overall vacuum heat treatment needs to be clamped to ensure a large number of position and dimensional accuracy, and it is easy to cause new deformation out of tolerance, and the special heat treatment shape correction fixture has a complex structure, is difficult to manufacture, and is expensive
