Guide unit guide roller cooling system

Abstract

The invention discloses a guide unit guide roller cooling system. The guide unit guide roller cooling system comprises a guide unit, a guide roller supporting arm is fixedly arranged on one side of the guide unit, a cold water pipe is arranged at the top of the guide roller supporting arm and is fixedly connected with the guide unit, a spraying head is arranged on the cold water pipe, one end of the cold water pipe is connected with a water inlet pipe, a water pump motor is arranged on one side of the water inlet pipe, a guide roller is arranged on the guide roller supporting arm, and a temperature control device is arranged on the guide roller. According to the guide unit guide roller cooling system, a heat conduction bar and a shape memory alloy are arranged, and therefore the heat conduction bar can better transmit the temperature of the guide roller to the shape memory alloy, and the shape memory alloy is controlled to extend and contract; and a supporting frame, an electrode plate and an electric contact bar are arranged, and therefore the shape memory alloy can better deform to control the supporting frame to ascend and descend, the supporting frame ascends and descends to control contact between the electrode plate and the electric contact bar, starting and stopping of the water pump motor are controlled, constant work of the water pump motor is avoided, energy resources are saved, and the water resource is saved.

Description

technical field [0001] The invention relates to the field of guide devices, in particular to a cooling system for guide rollers. Background technique [0002] The guide rollers on the existing guides work for a long time, due to contact and friction with the steel rolling, the phenomenon of heat generation of the guide rollers is serious, because the hardness and wear resistance of the metal at high temperatures are reduced, so the guide rollers at high temperatures and the steel rolling Continued contact friction will further accelerate the wear of the guide roller and reduce the service life of the guide roller. In the prior art, the method of spraying cold water on the guide roller is often used to cool it down. For example, patents 2016212308840 and 2016211875641 spray cold water through the guide roller through the pipeline This way of cooling is not highly automated, it cannot detect the real-time temperature of the guide rollers, and it is easy to cause waste of water...

[0002] The guide rollers on the existing guides work for a long time, due to contact and friction with the steel rolling, the phenomenon of heat generation of the guide rollers is serious, because the hardness and wear resistance of the metal at high temperatures are reduced, so the guide rollers at high temperatures and the steel rolling Continued contact friction will further accelerate the wear of the guide roller and reduce the service life of the guide roller. In the prior art, the method of spraying cold water on the guide roller is often used to cool it down. For example, patents 2016212308840 and 2016211875641 spray cold water through the guide roller through the pipeline This way of cooling is not highly automated, it cannot detect the real-time temperature of the guide roller, and it is easy to cause waste of water resources. Therefore, it is necessary to invent a cooling system for guide rollers to solve the above problems
