Abstract
The invention discloses a manufacturing process of a grinding and rolling wheel. The manufacturing process comprises a grinding material belt preparation step and a grinding material belt rolling step, specifically, a nylon three-dimensional base belt and a grinding and bonding composition are selected and blended, and the grinding and bonding composition is sprayed on the nylon three-dimensional base belt and curing is carried out to form a grinding material belt; winding coating glue is selected, traction and stretching are carried out on the grinding material belt, the traction and stretching opening degree is maintained, roller coating of the winding coating glue is carried out, and after roller coating, tightening and rolling are carried out to form a grinding and rolling wheel blank; and baking and curing are carried out the ground and rolled wheel blank. The prepared grinding and rolling wheel has a very stable structure, no layering phenomenon exists in the using process, the compression deformation quantity is very small, and the grinding uniformity is very remarkable; through softening and stretching before winding and coating, the permeability and binding degree of the winding coating glue are greatly improved, and the a relatively firm binding force is achieved after thermocuring; and a specific formula combination is adopted, so that the requirements of grinding particle uniformity and bonding strength are met, and meanwhile, the service life of the grinding and rolling wheel is prolonged.
Description
technical field [0001] The invention relates to a manufacturing process of a grinding winding wheel, which belongs to the technical field of grinding winding wheels. Background technique [0002] The traditional take-up wheel is made by coating the colloid on a special tube core by the method of roller glue coating, winding it into a rod, and baking and curing it. The colloid contains binders and abrasives, etc., and the distribution uniformity of the abrasives in the colloid is poor. After forming, the grinding uniformity of the take-up wheel is poor, and the grinding quality is unstable. [0003] In response to this situation, a take-up wheel with a nylon base material as the base material appears, that is, the nylon base material is sand-planted and then the roll coating colloid is baked and cured. There are several difficulties that need to be overcome. The first is the coating There is poor compatibility between the cloth colloid and the sand planting colloid, which le...
