Description

Technical Field

[0001] The utility model relates to the technical field of producing grinding wheel slices, in particular to a resin grinding wheel hardening separator used for producing grinding wheel slices. Background Art

[0002] Grinding wheels are the most important type of abrasive tools in grinding. Grinding wheels are porous bodies made by adding a binder to abrasives, pressing, drying and sintering. If the grinding wheels currently produced in China are too thick, the cutting performance and efficiency of the grinding wheels will be poor. If the grinding wheels are too thin, the cutting stability of the grinding wheels will be poor. Therefore, it is necessary to produce a grinding wheel with a reinforced core, that is, the thickness of the core is increased, and the thickness of the cutting part is smaller than that of the core. The grinding wheel with this structure has high cutting performance and high cutting efficiency. During the production of the grinding wheel, the abrasive needs to be poured into the mold. At this time, a separator is placed in the mold to ensure that the grinding wheel is formed. However, the separator in the prior art is a single layer, and can only produce a flat grinding wheel.

[0003] The patent publication number CN113649957B was retrieved, and the patent name is a public material of a rail cutting grinding wheel with a surface coating and a preparation method thereof, and specifically discloses an optimization of a preparation method for a rail cutting grinding wheel. The specific preparation method of the grinding wheel blank described in step (5) is: using two glass fiber meshes to make a process: placing a glass fiber mesh, baking the mesh, pressing the mesh, adding the mixture 3 after soaking and placing, placing another glass fiber mesh, and pressing it using a hot pressing mold; using three glass fiber meshes to make a process: placing a glass fiber mesh, baking the mesh, pressing the mesh, adding the mixture 3 after soaking and placing, then placing another glass fiber mesh, baking the mesh, pressing the mesh, adding the mixture 3 after soaking and placing, placing the last glass fiber mesh, and pressing it using a hot pressing mold.

[0004] By analyzing the above-mentioned public materials, it can be known that the grinding wheel produced by this method has a planar structure and does not have the effect of strengthening the core. Utility Model Content

[0012] Furthermore, the bottom net includes warp threads and weft threads, which are formed by interweaving.

[0026] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-5 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0027] like Figure 1-5 As shown: Example

[0028] A resin grinding wheel hardening spacer for producing grinding wheel discs includes a base net 1; a pad net 2, which is arranged on the upper end surface of the base net 1 and fixedly connected to the base net 1; small holes 3, which are arranged on the base net 1; large holes 4, which are arranged on the pad net 2; the axes of the small holes 3 and the large holes 4 coincide, and the inner diameter of the large holes 4 is larger than that of the small holes 3, and a height difference is formed between the large holes 4 on the pad net 2 and the small holes 3 on the base net 1, which is used to form a reinforcement for the grinding wheel core.

[0029] In this embodiment, the spacer net used in the present technology for making the grinding wheel 7 includes a bottom net 1 and a pad net 2. Small holes 3 are provided on the bottom net 1, and large holes 4 are provided on the pad net 2. The axes of the large holes 4 and the small holes 3 coincide, and the inner diameter of the large hole 4 is larger than the inner diameter of the small hole 3. Due to the addition of the pad net 2, there is a height difference between the large hole 4 and the small hole 3. The spacer net is laid in the mold, and then the abrasive is poured into the mold. After pressurization, the grinding wheel 7 has a core-thickened structure, thus forming a core-reinforced grinding wheel 7. Example

[0030] The bottom net 1 includes warp threads 5 and weft threads 6, which are formed by interweaving.

[0031] Different from the above embodiment, in this embodiment, the bottom net 1 is formed by interweaving the warp threads 5 and the weft threads 6 in the vertical and horizontal directions, and the threads are made of high-twisted glass fiber cloth. Example

[0032] The mat net 2 includes warp threads 5 and weft threads 6, which are interwoven.

[0033] Different from the above embodiment, in this embodiment, the mat net 2 is also formed by interweaving the warp threads 5 and the weft threads 6 in the vertical and horizontal directions, and the threads are made of high-twist glass fiber cloth. Example

[0034] There are a number of the mat nets 2 distributed in layers, and the inner diameters of the large holes 4 on the mat nets 2 are the same.

[0035] Different from the above embodiment, in this embodiment, the number of pad nets 2 can be set according to the thickness of the core that needs to be reinforced. When the number of pad nets 2 is large, the thickness of the reinforced core will also be larger. Example

[0036] An adhesive layer 8 is provided between the bottom net 1 and the pad net 2. The adhesive layer 8 is solidified by modified Teflon glue. The bottom net 1 and the pad net 2 are both soaked in the modified Teflon glue and fixed after being squeezed.

[0037] Different from the above embodiment, in this embodiment, the high-twist glass fiber cloth is soaked in modified Teflon glue and then squeezed and fixed. At this time, the middle layer is the adhesive layer 8, and the ends of the pad net 2 and the bottom net 1 are both covered with solidified modified Teflon glue, which can not only play the role of a tray, but also has the effect of not sticking to the grinding wheel 7.

[0038] The working method (or working principle) of this utility model:

[0039] When this technology is working, the bottom mesh 1 is made into high-twist glass cloth by woven vertically and horizontally, and the pad mesh 2 is cut through the large hole 4 mold to form the large hole 4, and then soaked in modified Teflon glue and squeezed and fixed together to form a partition structure of a single-layer pad mesh 2. If multiple layers are needed, multiple layers of pad mesh 2 can be added. When in use, the partition mesh is placed at the bottom of the mold, and then the abrasive of the grinding wheel 7 is poured into the mold. After pressurization, a core-reinforced grinding wheel 7 is formed. The formation of the core is the position of the large hole 4 and the height difference between the large hole 4 and the small hole 3.

Unless otherwise clearly specified and limited, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0041] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
