Abstract
Description
Technical Field
[0001] This utility model relates to the field of resin grinding wheel technology, and in particular to an explosion-proof resin grinding wheel with good heat dissipation. Background Technology
[0002] Resin grinding wheels are grinding wheels made of resin. They have high strength and are used in cutting discs, double-end grinding wheels, heavy-duty grinding wheels, polishing wheels, etc. They are widely used for rough grinding, rough grinding, cutting and free grinding, such as grinding steel ingots and deburring castings.
[0003] Currently, resin grinding wheels generate a lot of heat during high-speed friction with the workpiece during the cutting process. If the heat cannot be dissipated, it will travel from the edge of the resin grinding wheel to its interior and surface, which can cause the resin grinding wheel to suddenly burst or deform, rendering it unusable. Therefore, there is a need for an explosion-proof resin grinding wheel with good heat dissipation. Utility Model Content

This can solve the problem that the resin grinding wheel generates a lot of heat during the cutting process when it rubs against the workpiece at high speed, which can cause the resin grinding wheel to suddenly burst or deform, making the resin grinding wheel unusable for the next time.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof resin grinding wheel with good heat dissipation, comprising a cutting disc body;

[0009] The resin base layer has reinforcing mesh on both its upper and lower surfaces. Both reinforcing meshes are fixedly connected to the resin base layer. By setting two reinforcing meshes, the internal structural strength of the cutting disc body can be increased.
[0010] Preferably, heat insulation layers are provided on the opposing surfaces of the two reinforcing meshes, and the two heat insulation layers are fixedly connected to the two reinforcing meshes. The heat insulation layers are made of white corundum abrasive, which has sharp edges and good cutting performance. It also generates little heat during grinding, which can reduce the heat generation of the cutting disc body and prevent the two reinforcing meshes and the resin base layer from deforming due to high temperature. Heat insulation coatings are provided on the opposing surfaces of the two heat insulation layers.
[0011] Preferably, a heat dissipation layer is provided on the opposite surfaces of the two heat insulation layers. The two heat dissipation layers are arranged in a cross shape and are fixedly connected to the two heat insulation layers respectively. The material of the two heat dissipation layers is brown fused alumina sand. The Mohs hardness of brown fused alumina sand can reach level 9 or above. Under high temperature and high pressure, it can still maintain good strength and stability, is not easy to break, and has high thermal conductivity, which can dissipate heat quickly.
[0012] Preferably, a fixing steel pipe is fixedly sleeved on the cutting disc body, the two reinforcing meshes, the two heat insulation layers, and the two heat dissipation layers. The fixing steel pipe is made of a metal material with good thermal conductivity.

[0019] (2) The explosion-proof resin grinding wheel with good heat dissipation can increase the internal structural strength of the cutting disc body by setting two reinforcing meshes, so that the force borne by the cutting disc body is evenly distributed on the two reinforcing meshes and the resin base layer, preventing the resin grinding wheel from suddenly bursting during high-intensity work.
[0020] (3) The explosion-proof resin grinding wheel with good heat dissipation can prevent excessive heat transfer from the two heat dissipation layers to the two heat insulation layers by setting heat insulation coatings on the opposite sides of the two heat insulation layers, which would cause the temperature inside the cutting disc body to be too high.

Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0030] Please see Figure 1-3This utility model provides a technical solution: an explosion-proof resin grinding wheel with good heat dissipation, including a cutting disc body 1, with multiple first heat dissipation holes 2 arranged in a cross pattern on the upper and lower surfaces of the cutting disc body 1, and a resin base layer 8 disposed inside the cutting disc body 1.
[0031] The upper and lower surfaces of the resin base layer 8 are provided with reinforcing mesh 9. Both reinforcing mesh 9 are fixedly connected to the resin base layer 8. By setting two reinforcing mesh 9, the internal structural strength of the cutting disc body 1 can be increased, so that the force borne by the cutting disc body 1 is evenly distributed on the two reinforcing mesh 9 and the resin base layer 8, preventing the resin grinding wheel from suddenly bursting during high-intensity work.
[0032] Furthermore, heat insulation layers 10 are provided on the opposing surfaces of the two reinforcing meshes 9. The two heat insulation layers 10 are fixedly connected to the two reinforcing meshes 9. The heat insulation layer 10 is made of white corundum abrasive, which has sharp edges and good cutting performance. It generates little heat during grinding, which can reduce the heat generation of the cutting disc body 1 and prevent the two reinforcing meshes 9 and the resin base layer 8 from deforming due to high temperature. This improves the service life of the resin grinding wheel cutting disc. Heat insulation coating is provided on the opposing surfaces of the two heat insulation layers 10.
[0033] Furthermore, heat dissipation layers 4 are provided on the opposite surfaces of the two heat insulation layers 10. The two heat dissipation layers 4 are arranged in a cross shape and are fixedly connected to the two heat insulation layers 10 respectively. The material of the two heat dissipation layers 4 is brown fused alumina sand. The Mohs hardness of brown fused alumina sand can reach level 9 or above. Under high temperature and high pressure, it can still maintain good strength and stability, is not easy to break, and has high thermal conductivity, which can dissipate heat quickly.
[0034] By setting two heat dissipation layers 4, the strength of the cutting disc body 1 can be further enhanced. When the cutting disc body 1 is working, the heat generated at the edge of the cutting disc body 1 can be quickly guided to the two heat dissipation layers 4. With the help of two sets of cross-shaped first heat dissipation holes 2, the heat can be quickly discharged, thereby improving the heat dissipation of the resin grinding wheel. The two heat dissipation layers 4 are fixedly connected to the cutting disc body 1. By setting heat insulation coating on the two heat insulation layers 10 opposite to each other, it can be prevented that too much heat on the two heat dissipation layers 4 is transferred to the two heat insulation layers 10, which would cause the temperature inside the cutting disc body 1 to be too high.
[0035] Furthermore, a fixing steel pipe 5 is fixedly sleeved on the main body 1 of the cutting disc, the two reinforcing meshes 9, the two heat insulation layers 10, and the two heat dissipation layers 4. The fixing steel pipe 5 is made of a metal material with good thermal conductivity.
[0036] The fixed steel pipe 5 is hollow inside, and the upper and lower surfaces of the fixed steel pipe 5 are provided with second heat dissipation holes 6 that communicate with it. By setting the fixed steel pipe 5, the heat from the cutting disc body 1, the two reinforcing meshes 9, the two heat insulation layers 10, and the two heat dissipation layers 4 can be transferred to the interior of the fixed steel pipe 5, and then the heat can be discharged through multiple second heat dissipation holes 6, thereby further improving the heat dissipation of the resin grinding wheel.
[0037] Furthermore, the upper and lower outer walls of the fixed steel pipe 5 are both fixedly fitted with annular sleeves 7. Both annular sleeves 7 are fixedly connected to the cutting disc body 1. The two annular sleeves 7, together with the fixed steel pipe 5, can enhance the structural strength between the cutting disc body 1, the two reinforcing meshes 9, the two heat insulation layers 10, and the two heat dissipation layers 4.
[0038] Furthermore, four mounting holes 3 are provided on the cutting disc body 1, the two reinforcing meshes 9, the two heat insulation layers 10, the two heat dissipation layers 4, and the two annular sleeves 7. The four mounting holes 3 are used for mounting the cutting disc body 1 as a whole to external instruments.
[0039] Working principle: By setting two reinforcing meshes 9, the internal structural strength of the cutting disc body 1 is increased, so that the force borne by the cutting disc body 1 is evenly distributed on the two reinforcing meshes 9 and the resin base layer 8, preventing the resin grinding wheel from suddenly bursting under high-intensity operation. The heat insulation layer 10 is made of white corundum abrasive, which has sharp edges and good cutting performance with low grinding heat, reducing the heat generation of the cutting disc body 1 and preventing deformation of the two reinforcing meshes 9 and the resin base layer 8 due to high temperature, thus improving the service life of the resin grinding wheel cutting disc. By setting two heat dissipation layers 4, the strength of the cutting disc body 1 can be further strengthened, and the heat generated at the edges of the cutting disc body 1 can be dissipated when the cutting disc body 1 is working. The heat is quickly guided to the two heat dissipation layers 4, and with the cooperation of two sets of cross-shaped first heat dissipation holes 2, the heat is quickly discharged. By setting heat insulation coating on the two heat insulation layers 10 opposite to each other, it is possible to prevent excessive heat transfer from the two heat dissipation layers 4 to the two heat insulation layers 10, which would cause the temperature inside the cutting disc body 1 to be too high. By setting a fixed steel pipe 5, the heat from the cutting disc body 1, the two reinforcing meshes 9, the two heat insulation layers 10, and the two heat dissipation layers 4 can be transferred to the inside of the fixed steel pipe 5, and then discharged through multiple second heat dissipation holes 6. The two annular sleeves 7 and the fixed steel pipe 5 can enhance the structural strength between the cutting disc body 1, the two reinforcing meshes 9, the two heat insulation layers 10, and the two heat dissipation layers 4.
[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
