Abstract

The invention discloses a grinding roller shock absorption grinding wheel adjustable in hardness. Composition of the grinding roller shock absorption grinding wheel comprises white fused alumina, single-crystal corundum, black silicon carbide, phenolic resin liquid, phenolic powder, epoxy resin, sodium salt, ice crystal powder, and pyrite ore powder. The grinding roller shock absorption grinding wheel utilizes dissolution action of water in cooling liquid on the sodium salt in the composition of the sand wheel, and controls dissolution speed of the sodium salt by controlling cooling liquid flow. The strength of resin binder bonding grinding material is gradually reduced in the process that the sodium salt is gradually dissolved by water. The purpose of reducing the hardness of the sand wheel in a controllable mode can be achieved in the process. The grinding roller shock absorption grinding wheel is adjustable in hardness and strong in universality, greatly reduces the number of grinding roller grinding machines configured by a user, simultaneously greatly reduces labor amount and auxiliary work hours for frequent replacing of grinding wheels, and is favorable to improving production efficiency of grinding and cutting rollers.

Description

technical field [0001] The invention relates to an abrasive abrasive tool, in particular to a vibration-eliminating grinding wheel for grinding rolls with adjustable hardness. Background technique [0002] The surface quality of steel plates used to manufacture automobile shells is very high, and its surface quality mainly depends on the surface quality of the rolls used in rolling. The rolls in the plate rolling machine are in direct contact with the rolled steel plate. There is a small amount of wear during the rolling process. When the wear of the roll reaches a certain amount, it must be ground before it can continue to be used. The grinding process adopts the cylindrical grinding process. The rolls on the rolling mill are divided into main rolls, back-up rolls and traction rolls. Due to different functions, the materials used are very different. The hardness of different types of metal materials is quite different, and it is necessary to configure a grinding wheel with...
