Embodiment Construction

[0020] An intelligent welding seam stress treatment and impact equipment includes: piezoelectric ceramic stack 1, horn 2, light control lamp 3, camera 4, impact needle 5, driving mechanism 6, and controller 7. The piezoelectric ceramic stack 1 is applied with a certain frequency AC voltage at both ends, which can cause the phenomenon of piezoelectric resonance. The generated ultrasonic high-frequency vibration is then amplified by the horn 2 to act on the The impact needle 5 mentioned above. Through thousands of impacts per second, the residual stress in the weld toe is quickly released to achieve the effect of stress relief. The present invention proposes an innovation to the mechanical structure of the impact head. The traditional single-row impact needle structure is improved into two rows of vertically arranged impact needles that can be controlled by a lateral movement mechanism. The movement direction is controlled by the drive mechanism 6 The opposite lateral movement m...

Abstract

The invention discloses intelligent post-welding treatment equipment. A piezoelectric ceramic stack is connected with an amplitude-change pole, the amplitude-change pole is connected with a transverseexecuting mechanism, the transverse executing mechanism is fixedly connected with two rows of impacting needles and driven by a driving mechanism; a camera for collecting welding line images is further arranged, and an optical control lamp is arranged on the near side of the camera; a controller controls the driving mechanism, the camera and the optical control lamp to work; and the vertically arranged two rows of the impacting needles process welding toes on two sides of a welding line correspondingly, and through a transvers moving mechanism, the moving directions of the two rows of the impacting needles are opposite and aim at the welding toes on the two sides of the welding line. According to the intelligent post-welding treatment equipment, the structure is reasonable, the working efficiency is high, and the welding toes on the two sides of the welding line can be processed synchronously.

Description

[0001] This application is a divisional application with the application number: 201711427087.0, application date: 2017-12-26, with the name "intelligent weld stress treatment and impact equipment". Technical field [0002] The invention relates to an intelligent welding seam stress processing impact equipment. Background technique [0003] Welding plays a pivotal role in the manufacturing industry, and it has become increasingly widespread in all walks of life in modern industry. With the advancement of science and technology, people have higher and higher requirements for welding quality. After the end of welding, the uneven temperature field of the welding field leads to the generation of residual stress. The residual stress will affect the fatigue strength of the weld, and the yield strength will be greatly reduced. As a result, the service life of the entire weld will be greatly reduced. Among the existing methods for welding residual stress, the ultrasonic treatment method ...
