Stress relief aging device

Abstract

The invention provides a stress relief aging device for a large box type welding component. The stress relief aging device is provided with a thermal aging furnace and a movable vibration table. The movable vibration table is provided with a walking mechanism so that the movable vibration table can move. When a workpiece is subjected to aging treatment, the workpiece is firstly fixed on the movable vibration table, and the workpiece is fed into the thermal aging furnace through the movable vibration table to be synchronously subjected to thermal and vibration loading, so that the workpiece issubjected to thermal and vibration comprehensive aging treatment to reduce the welding residual stress of the workpiece. By means of the device, the technical problems that in the prior art, a destressing device is single, and the combination of thermal aging and vibration aging is not considered are solved; and meanwhile, the movable vibration table can be moved into or out of the thermal aging furnace, and the workpiece can be disassembled and assembled after being moved out of the thermal aging furnace along with the movable vibration table, so that the workpiece is disassembled and assembled more flexibly.

Description

technical field [0001] The invention relates to a stress relief aging device, in particular to a thermal-vibration comprehensive aging device for reducing the residual stress at the welding position of a large box-type component. Background technique [0002] Metals or alloys will generate large residual stress inside the weldment after welding. If it is not treated effectively, it will cause quality problems such as deformation and fatigue cracking of the weld and heat-affected zone, and seriously shorten the service life of the workpiece. At present, there are many methods to eliminate or reduce the residual stress of welded components, such as natural aging, ultrasonic aging, thermal aging and vibration aging, etc., but there is no effective device and corresponding implementation standards for the reduction of residual stress of large box-type welded components. [0003] Large-scale box-type welded components are often used in workpieces such as converter cabinets and ba...

AI Technical Summary

Problems solved by technology

[0005] 1. In engineering applications, the stress relief process of large welded components lacks corresponding implementation standards and equipment;

[0006] 2. The single thermal aging or vibration aging method has limited ability to reduce residual stress;

[0007] 3. Vibration tables in engineering applications are usually bulky, poor in flexibility, and inconvenient to carry and move;

[0008] 4. The vibration aging process needs to customize a suitable vibration table for workpieces of different specifications and shapes in engineering applications, and the versatility is not strong
