Abstract

The invention relates to a grinding wheel mesh heating and cutting method. The method comprises the following steps that: S1, conveying a grinding wheel mesh adhesive tape; S2, adjusting the distance; S3, heating and preserving heat; and S4, carrying out cutting and forming. A heating assembly is adopted for heating a felt conveying belt to different temperatures according to the grinding wheel mesh adhesive tape with different gram weights, the grinding wheel mesh adhesive tape is arranged on the felt conveying belt, and the grinding wheel mesh adhesive tape is indirectly heated through utilizing the heat preservation performance of the felt conveying belt, thus the grinding wheel mesh adhesive tape is prevented from being damaged due to direct heating of the adhesive tape on a grinding wheel mesh, the grinding wheel mesh adhesive tape can be effectively subjected to heat preservation and softening, finally cutting is conducted, flash or white edges are effectively prevented from being generated on the edge of the grinding wheel mesh, the cutting quality of the edge of the grinding wheel mesh is guaranteed. the bonding strength of the grinding wheel mesh to resin and grinding materials during subsequent grinding wheel manufacturing is not affected, the use feeling of a finished grinding wheel is improved, and the actual service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of grinding wheel mesh cutting, in particular to a method for heating and cutting a grinding wheel mesh. Background technique [0002] The grinding wheel mesh is used as the reinforcing base material of the grinding wheel to enhance the tensile performance of the grinding wheel. In the production process, firstly, the mesh needs to be punched into circular meshes, then the punched meshes are picked up, and finally the grinding wheel meshes are inspected to screen out unqualified meshes. [0003] However, in the prior art, the adhesive cloth on the grinding wheel net is directly punched into a circular mesh, and the hardness of the rubber cloth on the grinding wheel net is relatively high, and there will be flashes or white edges at the edge of the punched grinding wheel net, which will affect the subsequent manufacturing of the grinding wheel. The bonding strength of the grinding wheel mesh to the resin and...
