Background technique

At present, in the field of mechanical processing, there are mainly two methods for aging treatment of metal workpieces: thermal aging and vibration aging. Among them, the vibration aging process uses mechanical methods to vibrate the metal workpiece, and applies cyclic dynamic stress to the workpiece under resonance conditions, so that the residual stress inside the workpiece can be relaxed or redistributed, so as to achieve the purpose of stabilizing the mechanical properties and dimensions of the metal workpiece. Compared with thermal aging treatment, vibration aging process is widely used and developed rapidly due to its advantages of environmental protection, high efficiency and low cost. the

In the vibration aging process, a vibration damping support device is usually installed to transmit the vibration generated by the vibration aging equipment to the ground, so as to play the role of buffering and reducing vibration, so as to reduce the vibration and noise generated during the vibration aging process. . the

Most of the existing vibration-aging damping support devices use rubber damping support devices. The rubber damping support device only relies on its rubber damping pad as a single-stage vibration damping support, and the vibration damping effect is relatively poor, and the vibration damping efficiency is low. When under high pressure, it is easy for the rubber pad to lose its elasticity due to excessive force, which seriously affects the overall vibration reduction effect of the vibration aging process, and makes the place where the vibration aging process is implemented have greater vibration and noise. In severe cases, it can affect the health of the operator and the quality of the surrounding environment. the

Therefore, how to improve the damping capacity and efficiency of the damping support device and reduce the vibration and noise generated during the vibration aging process is an important technical problem to be solved by those skilled in the art. the
