Description

Technical Field

[0001] The present application relates to the technical field of vibration equipment, and more specifically, to a vibration aging treatment device. Background Art

[0002] In metallurgical equipment and rotary kilns, welded steel structures are increasingly being used in place of castings. Large welded components, due to the high volume of welding, can generate residual stress within the components. This residual stress is detrimental to the strength and stability of the structure. For large housings, residual stress can cause deformation, also significantly damaging the components.

[0003] After searching, the existing patent document with announcement number CN201470586U provides a vibration aging device, which fixes the exciter and the small workpiece on a platform. The disc platform can be regarded as a carrier, realizing the resonance of the exciter and the small workpiece, and solving the problem of being unable to perform vibration aging treatment on the small workpiece due to the inability to fix the exciter and the small workpiece together for vibration.

[0004] Although the above device can perform vibration aging treatment on small workpieces, it cannot perform vibration aging treatment on large welded components. In view of this, we propose a vibration aging treatment device. Utility Model Content

[0029] The workpiece is placed on a support pad 1, and the vibration pickups 4 are evenly distributed on the workpiece surface. The vibration exciter 3 is then fixed to the workpiece via a mounting bracket 2. The vibration exciter 3 is controlled to drive the workpiece to vibrate, thereby performing an aging treatment and eliminating residual welding stress within the workpiece. The vibration pickup 4 can also be used to obtain the vibration characteristics of different parts of the workpiece. Based on the vibration characteristics of the workpiece, the excitation parameters of the vibration exciter 3 can be adjusted to change the workpiece vibration until the workpiece reaches a resonant state.
