Abstract

The invention discloses a method for grinding a rubber roll and application thereof, and belongs to the technical field of rubber roll grinding. The method for grinding a rubber roll comprises the following steps: (1) preparing an abrasive belt and a wood block; (2) wrapping the abrasive belt on the wood block, to make a wood block wrapped by the abrasive belt, ensuring the wood block has at leastthree continuous surfaces wrapped by the abrasive belt, then fixing the wood block wrapped by the abrasive belt on a knife rest of a rubber roll lathe; (3) fixing a to-be-grinded rubber roll on a rotating shaft of the rubber roll lathe, then adjusting feed amount of the rubber roll lathe, so that the abrasive belt contacts with the to-be-grinded rubber roll, starting the rubber roll lathe, driving the rotating shaft to rotate, and controlling feeding speed, to grind the rubber roll. The method can be applied on rubber rolls whose diameter range is 80 mm to 2100 mm, and the method can effectively eliminate appearance defects which influence accurate grinding on the surface of the rubber roll. The method also improves grinding dimension accuracy, and effectively reduces use amount of the abrasive belts.

Description

technical field [0001] The invention belongs to the technical field of grinding rubber rollers, and in particular relates to a method for grinding rubber rollers and an application thereof. Background technique [0002] Cots are widely used in steel, paper and other industries. Due to different working conditions, the performance requirements of the rubber material of the rubber roller are different, and the parameters such as elasticity, strength and hardness of the rubber material are very important to the temperature, pressure and speed during grinding. Sensitive, so that when the rubber roller is ground by the conventional method of directly wrapping the rubber roller with the abrasive belt, the surface of the rubber roller material will be sticky, the dimensional accuracy is not high, and the grinding efficiency is low. This seriously affects the efficiency and quality of subsequent fine grinding and polishing. The common follow-up fine grinding and polishing needs to ...
