Problems solved by technology
[0003] At present, the existing methods for eliminating the residual stress of ultra-high-strength steel include mechanical stretching, thermal aging, and natural aging. The most commonly used methods are thermal aging and natural aging. The application of thermal aging and natural aging is not widely used, but the production efficiency is low, the cycle is long, the floor space is large, and thermal aging also consumes a lot of energy, which makes these two methods gradually no longer Adapt to the development needs of modern industrial society

Abstract
The invention provides a magnetic resonance and ageing compound residual stress reduction device, which comprises a resonance ageing system and a magnetic treatment system, wherein the resonance ageing system comprises a resonance table, a supporting framework and a tension applying mechanism; the supporting framework is arranged above the resonance table and is fixedly connected with the resonance table; a first sample connection piece is arranged on the supporting framework; a second sample connection piece is correspondingly arranged on the tension applying mechanism; a resonance exciting head is arranged on the resonance table; the resonance exciting head is arranged between the first sample connection piece and the second sample connection piece; the magnetic treatment system is arranged on the supporting framework above the resonance table; the magnetic treatment system comprises a magnetic body and a magnetic controller; the magnetic body is connected with the controller. By arrangement of the resonance ageing system and the magnetic treatment system, the magnetic treatment system is arranged on the supporting framework above the resonance table, so that homogenization of residual stress is completed by the compounding action of magnetic field treatment and resonance ageing.
Description
technical field [0001] The invention relates to the technical field of metal material processing, in particular to a magnetic vibration composite aging residual stress relief device. Background technique [0002] In recent years, after metal components are processed by heat or pressure, residual stress will be generated on the surface and inside. The existence of residual stress makes the workpiece in an unstable state, which is the main reason for the cracking or deformation of the workpiece. Ultra-high-strength steel is a steel with a very wide range of applications. Its high tensile strength, good toughness, high specific strength, and high yield ratio make it a kind of steel used in various fields such as automobiles, aviation, aerospace, military, and industry. Materials with important value in the field are widely used in various components such as automobile anti-collision beams, skins of key parts of aircraft, gun barrels, gun barrels, and rocket launchers; however,...
