Problems solved by technology

In the traditional production process, resin grinding wheel cutting discs used cold-rolled plates as grinding wheel separators in the early stage. The disadvantages are that they are easily deformed during use and cannot be repaired. The disadvantage of the grid cloth as a partition is that when the grinding wheel slices are separated and stacked for hardening, it is not conducive to temperature and heat transfer, and it is easy to cause inconsistent hardening temperatures inside and outside the grinding wheel slices, resulting in quality decline. The number of reused glass fiber mesh is limited and scrapped. Unable to decompose at the time, causing environmental waste and endangering the environment

Embodiment 1

[0019] A method for preparing a special spacer for resin grinding wheel slice hardening, comprising the following steps:

[0020] S1. Use a wire mesh with an outer diameter larger than the outer diameter of the grinding wheel slices to be punched into a wire mesh by a punching machine;

[0021] S2. Evenly smear white industrial silicone oil on the wire mesh obtained in step S1, then flatten it into a furnace, and obtain a special mesh after keeping it warm for a period of time.

[0022] The invention uses the improved barbed wire mesh as the partition net, compared with the traditional cold-rolled plate and glass fiber mesh cloth as the partition net, which has a better separation effect and will not make the grinding wheel slices stick together.

Embodiment 2

[0024] On the basis of Example 1, in step S1, the mesh number of the barbed wire is 40 meshes, and the mesh number of the barbed wire is selected according to needs, and the applicability is strong.

Embodiment 3

[0026] On the basis of Example 1, in step S1, the mesh number of the barbed wire is 50, and the mesh number of the barbed wire is selected according to needs, which has strong applicability.

Abstract

The present invention relates to the technical field of making grinding wheel slices, in particular to a method for preparing a special partition for resin grinding wheel slice hardening; it includes the following steps: S1, adopting a wire mesh with an outer diameter larger than that of the grinding wheel slice and punching it into a wire partition through a punching machine; S2, in step White industrial silicone oil is evenly applied on the iron wire mesh obtained in S1, and then it is flattened and installed in a furnace. After a period of heat preservation, a special mesh can be obtained; the grinding wheel can be fully separated during the hardening process, and the mesh can be recycled.

Description

technical field [0001] The invention relates to the technical field of making grinding wheel slices, in particular to a method for preparing a special partition for hardening resin grinding wheel slices. Background technique [0002] Grinding wheels are divided into three categories according to different binders: rubber bonded grinding wheels, resin bonded grinding wheels and vitrified bonded grinding wheels. With the advancement of reform and upgrading and the continuous development of industry, the proportion of resin grinding wheels in grinding wheel products has increased to more than 80%. It is developing at a high speed. In the traditional production process, resin grinding wheel cutting discs used cold-rolled plates as grinding wheel separators in the early stage. The disadvantages are that they are easily deformed during use and cannot be repaired. The disadvantage of the grid cloth as a partition is that when the grinding wheel slices are separated and stacked for...
