Description

Technical Field

[0001] The present invention relates to the technical field of vibration cylinder protection, and more specifically, to a vibration cylinder protection device and a protection method thereof. Background Art

[0002] In modern continuous casting equipment, due to stable amplitude, simple structure, and reliable control, vibration cylinders have gradually become the main vibration source of the vibration table. However, in actual use, due to external environments such as high temperature and dust, dust and foreign matters are likely to accumulate at the output shaft part of the piston rod of the vibration cylinder, resulting in surface scratches and running jams during the movement of the piston rod; at the same time, high-temperature radiation is likely to cause the aging of the piston rod sealing ring and oil leakage, affecting the working accuracy of the vibration cylinder and causing environmental pollution.

[0003] In the prior art, a straightening cylinder piston rod cooling device disclosed in CN211360591U adopts a design of an annular air duct with air blowing ports, and uses compressed air to cool the output part of the piston rod. However, its cooling capacity is weak, and its cooling effect cannot be guaranteed for the harsh working conditions in the vibration table area;

[0004] A hydraulic cylinder with a protection device disclosed in CN107654440A adopts an annular protection device, and uses an airbag to protect the output part of the piston rod. It has good sealing performance and little interference with the movement of the cylinder, but the heat resistance of the airbag is not strong, and it is easy to age and wear in a high-temperature environment, affecting its use. Summary of the Invention
