Problems solved by technology

This scheme uses the suction force of the electromagnet to attract the saw blade as the guiding force, so that the vibration control system is an unstable control type. Therefore, the control accuracy is limited, and it is easy to cause system instability.

Abstract

The invention discloses a saw blade guiding device and a regulation method thereof. Air-static guiding discs are arranged on the two sides of a saw blade to form a clearance; a stable-pressure air source P is used for providing compressed air; the compressed air is respectively conveyed to the guiding discs by pneumatic servo valves and then enters the clearance between the two sides of the saw blade so that pressure p1and pressure p2 are formed to apply a thrust to the saw blade. The pneumatic servo valves can control the size of the openings thereof according to signals sent from a controller so as to control the size of the pressure of outlets of the servo valves; vibration displacement and speed of the saw blade are measured by a displacement sensor and sent to the controller; the controller is used for controlling the pneumatic servo valves according to the signals of the displacement sensor. According to the device, a pneumatic force is used for controlling initiative vibration of guidance of the saw blade, and the air on the two sides of the saw blade are used for generating thrust, so that the vibration of the saw blade is controlled stably, the control precision can be increased, and the stability of the saw blade can be improved.

Description

technical field [0001] The invention relates to a saw blade guiding device and an adjusting method thereof. Background technique [0002] Saws play an important role in the entire engineering field and have been widely used in mining, petroleum, machinery, steel and other fields. [0003] Reducing the thickness of the saw blade can reduce the loss of the sawing road and save materials, so the saw blade is developing in a thinner direction; but after the thickness of the saw blade is reduced, the lateral stiffness becomes smaller, which deteriorates the stability of the saw blade during processing , the vibration is intensified, which leads to the decrease of sawing precision and surface quality, the increase of saw blade wear, and the decrease of saw blade life; at the same time, in order to improve production efficiency, it is necessary to increase the speed of the circular saw blade. Larger, significantly increased sawing noise, seriously polluting the environment. [00...
