Description

Technical Field

[0001] This utility model relates to the field of resin grinding wheel technology, and in particular to a resin grinding wheel for steel rails with a porous heat dissipation structure. Background Technology

[0002] Resin grinding wheels are a type of grinding tool. Their core feature is that they use synthetic resin as a binder to firmly bond many tiny abrasive particles together, and then cure them under high temperature and pressure. They are used for grinding, cutting, polishing and other processing of various materials.

[0003] A search revealed a resin grinding wheel with publication number CN210650265U, belonging to the field of grinding and polishing tools. It overcomes the shortcomings of existing grinding and polishing technologies, which suffer from poor efficiency and effectiveness. The wheel comprises a grinding wheel body and a polishing layer. The outer ring of the grinding wheel body has evenly distributed protrusions, and the inner ring of the polishing layer has grooves that mate and connect with the protrusions of the grinding wheel body. This invention improves the polishing speed and brightness of the workpiece, increases the strength of the grinding wheel, and enhances safety during use.

[0004] In the existing technology, rail grinding is a heavy-duty dry grinding process. The grinding wheel generates a large amount of concentrated grinding heat during operation, resulting in extremely high instantaneous temperatures in the grinding zone.

[0005] The device in the disclosed patent cannot dissipate heat in time during use. The accumulated heat not only damages the grinding wheel itself, but may also be transferred to the rail surface, causing changes in its metallographic structure, posing a safety hazard and making it less practical. Utility Model Content

[0006] In response to the technical problems in existing patents, such as the inability of the device to dissipate heat in time during use, which not only damages the grinding wheel itself but may also be transferred to the rail surface, causing changes in its metallographic structure and posing safety hazards, resulting in low practicality, this utility model provides a resin grinding wheel for rails with a porous heat dissipation structure.

[0007] The technical solution adopted in this utility model is: a resin grinding wheel with a porous heat dissipation structure, comprising:

[0008] A grinding wheel body, the grinding wheel body comprising a grinding wheel substrate and a resin abrasive layer mounted on top of the grinding wheel substrate;

[0009] A heat dissipation component is installed on the resin abrasive layer, and the heat dissipation component is used to increase the heat dissipation area and improve the heat dissipation effect.

[0010] The heat dissipation assembly includes an air inlet hole formed inside the resin abrasive layer, an air outlet hole formed on the top of the resin abrasive layer, and a heat dissipation channel formed inside the resin abrasive layer.

[0011] Furthermore, the grinding wheel body includes a grinding wheel substrate and a resin abrasive layer mounted on top of the grinding wheel substrate;

[0012] A heat dissipation component is installed on the resin abrasive layer, and the heat dissipation component is used to increase the heat dissipation area and improve the heat dissipation effect.

[0013] The heat dissipation assembly includes an air inlet hole formed inside the resin abrasive layer, an air outlet hole formed on the top of the resin abrasive layer, and a heat dissipation channel formed inside the resin abrasive layer.

[0014] Furthermore, the resin abrasive layer includes a heat dissipation layer, a support layer installed on the outside of the heat dissipation layer, and a wear-resistant layer installed on the outside of the support layer, wherein multiple layers of high-strength glass fiber mesh are embedded inside the support layer.

[0015] The beneficial effects of this utility model are:

[0016] External air enters the heat dissipation channel through the air inlet. As the grinding wheel rotates at high speed, the airflow flows rapidly within the heat dissipation channel. Due to the special design of the heat dissipation layer, heat is quickly transferred from the grinding area to the heat dissipation channel, where it exchanges heat with the airflow. After heat exchange, the hot airflow continues to flow along the heat dissipation channel and is finally discharged from the air outlet, thus achieving a highly efficient heat dissipation effect. The high-strength fiberglass mesh in the support layer not only enhances the overall strength of the grinding wheel but also ensures the structural stability of the heat dissipation layer and the wear-resistant layer under high temperature and high load working conditions, avoiding deformation or damage caused by thermal expansion and contraction.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described below.

[0027] To address the problems existing in the background art, this application proposes the following technical solution:

[0028] A resin grinding wheel with a porous heat dissipation structure for grinding steel rails includes: a grinding wheel body 1;

[0029] The grinding wheel body 1 includes a grinding wheel base 101 and a resin abrasive layer 102 mounted on top of the grinding wheel base 101.

[0030] like Figure 1-3 As shown, the heat dissipation component 2 is installed on the resin abrasive layer 102. The heat dissipation component 2 is used to increase the heat dissipation area and improve the heat dissipation effect.

[0031] The heat dissipation component 2 includes an air inlet 201 formed inside the resin abrasive layer 102, an air outlet 202 formed on the top of the resin abrasive layer 102, and a heat dissipation channel 203 formed inside the resin abrasive layer 102.

[0032] Furthermore, the air inlet 201, heat dissipation channel 203, and air outlet 202 are connected. When the grinding wheel rotates at high speed, it generates a strong centrifugal force. Air is drawn into the heat dissipation channel 203 from the air inlet 201, heated, and then thrown out from the air outlet 202. This process forms a continuous forced air cooling effect similar to breathing, which can efficiently remove heat.

[0033] Furthermore, the resin abrasive layer 102 includes a heat dissipation layer 3, a support layer 4 installed on the outside of the heat dissipation layer 3, and a wear-resistant layer 5 installed on the outside of the support layer 4. Multiple layers of high-strength glass fiber mesh are embedded inside the support layer 4.

[0034] Working principle: When the grinding wheel starts to grind the rail, the heat dissipation component 2 comes into play. External air enters the heat dissipation channel 203 through the air inlet 201. As the grinding wheel rotates at high speed, the airflow flows rapidly within the heat dissipation channel 203. Due to the special design of the heat dissipation layer 3, heat is quickly transferred from the grinding area to the heat dissipation channel 203 and exchanges heat with the airflow. After heat exchange, the hot airflow continues to flow along the heat dissipation channel 203 and is finally discharged from the air outlet 202, thereby achieving a highly efficient heat dissipation effect. The high-strength fiberglass mesh in the support layer 4 not only enhances the overall strength of the grinding wheel, but also ensures the structural stability of the heat dissipation layer 3 and the wear-resistant layer 5 under high temperature and high load working conditions, avoiding deformation or damage caused by thermal expansion and contraction.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings.
