Description

Technical Field

[0001] This utility model relates to the field of wear-resistant resin grinding wheel technology, specifically a self-sharpening wear-resistant resin grinding wheel. Background Technology

[0002] Resin-bonded grinding wheels are a commonly used grinding tool, widely applied in rough grinding, finishing, cutting, and free grinding of metals and non-metals. However, traditional resin-bonded grinding wheels suffer from poor self-sharpening and insufficient wear resistance, leading to easy dulling and frequent dressing, which not only reduces processing efficiency but also increases production costs. Furthermore, the poor wear resistance also results in a short wheel lifespan, requiring frequent replacements and further increasing operating costs.

[0003] Referring to Chinese Patent Publication No. CN204711842U, a heat-dissipating and wear-resistant resin grinding wheel is disclosed, comprising a through hole, a mounting layer, a heat dissipation layer, a fiber reinforcement mesh, an annular resin support disk, and a grinding layer. The heat dissipation layer is provided with multiple arc-shaped fan blades, which are radially distributed around the center of the through hole. The optimal angle A between the upper rotating inclined plane and the horizontal plane of the annular resin support disk is 15°, and the optimal angle B between the lower rotating inclined plane and the horizontal plane is 20°. This invention, by adjusting the angle between the upper and lower rotating inclined planes, can create an annular support disk with an annular trapezoidal shape. The thicker end of this support disk ensures the hardness of the annular bakelite support disk, while the thinner end ensures toughness.

[0004] In the aforementioned prior art, the hardness, heat dissipation, grinding force, self-sharpening ability, and grinding efficiency of the resin grinding wheel are improved by the angle between the lower rotating inclined plane 22 of the annular resin support disk 2 and the horizontal plane. However, the self-sharpening and wear resistance effects need further improvement. Heat dissipation is achieved through a heat dissipation layer and its internally arranged arc-shaped fan blades, but the heat dissipation effect needs further improvement.

[0005] The existing technology has the following technical problems: the self-sharpening property and heat dissipation effect of the existing self-sharpening wear-resistant resin grinding wheel need to be improved; therefore, we propose a self-sharpening wear-resistant resin grinding wheel to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a self-sharpening wear-resistant resin grinding wheel to solve the problems mentioned in the background art, such as the need to improve the self-sharpening property and heat dissipation effect of existing self-sharpening wear-resistant resin grinding wheels.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a self-sharpening wear-resistant resin grinding wheel, comprising a substrate, wherein a first heat dissipation structure and a second heat dissipation structure are installed in the substrate, the first heat dissipation structure is located inside the second heat dissipation structure, and a grinding tool is fixedly installed on the outside of the substrate.

[0008] The grinding tool includes a transition layer, a working layer, pores, and a strip groove. The working layer is provided on the outside of the transition layer. The working layer has longitudinal equal-angle pores. The working layer has axial equal-angle strip grooves and cutting textures on the outside of the working layer.

[0009] Preferably, the first heat dissipation structure includes a coolant chamber, a branch chamber, a first connecting pipe, a water pump, a second connecting pipe, and a valve. The coolant chamber has a branch chamber at an equal angle fixedly installed at one end near the outer ring of the base. The coolant chamber is fixedly connected to the first connecting pipe at one end away from the outer ring of the base. The first connecting pipe is fixedly connected to the water pump at one end away from the coolant chamber. The water pump is fixedly connected to the second connecting pipe at one end away from the first connecting pipe. A valve is installed at the second connecting pipe.

[0010] Preferably, the coolant chamber is disposed within the substrate.

[0011] Preferably, the branch chamber is located in the transition layer at the end furthest from the coolant chamber.

[0012] Preferably, the second heat dissipation structure includes a heat-conducting plate and heat dissipation ridges, which are respectively fixedly installed on the inner and outer sides of the substrate.

[0013] Preferably, the heat-conducting plates are respectively disposed at the upper and lower ends of the coolant chamber.

[0014] Preferably, the heat dissipation protrusions are fixedly installed at equal angles on the non-arc end of the outer side of the base.

[0015] Preferably, a substrate is fixedly installed within the transition layer.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the self-sharpening wear-resistant resin grinding wheel improves the self-sharpening performance of the resin grinding wheel through the design of the grinding cutter, enhances the friction and chip removal of the grinding wheel surface, and improves the heat dissipation effect through the combination of the first heat dissipation structure and the second heat dissipation structure.

[0017] 1. The grinding tool is equipped with a grinding cutter, which mainly consists of an inner and outer transition layer and a working layer. The abrasive concentration of the transition layer is lower than that of the working layer, so that the grinding tool forms a gradient abrasive layer.

[0018] Furthermore, the working layer is provided with longitudinally equidistant voids, which are formed by the high-temperature decomposition of pore-forming agents (naphthalene or polymer microspheres). Through the synergistic effect of the gradient abrasive layer and the porous structure, the passivated abrasive grains are promptly removed, and new abrasive grains are exposed, thereby improving the self-sharpening performance.

[0019] Furthermore, the outer side of the working layer is provided with axially equidistant grooves and cutting textures, and both the grooves and cutting textures are inclined at 45° clockwise. This design can enhance the friction and chip removal of the grinding wheel surface, while the fine grooves also help dissipate heat when grinding and cutting workpieces.

[0020] 2. A first heat dissipation structure is provided. The first heat dissipation structure injects cooling water into a coolant chamber in the substrate, and at the same time, the cooling water flows into branch chambers set at equal angles. The cooling water absorbs the cold energy on the resin grinding wheel, thereby uniformly cooling it.

[0021] Furthermore, the system is connected to an external pipeline via a second connecting pipe on one side, and the heated cooling water in the coolant chamber is extracted by a water pump on that side. The system is also connected to an external pipeline via a second connecting pipe on the other side, and the cooling water is pumped into the coolant chamber by a water pump on that side, thus ensuring the cooling effect of the cooling water.

[0022] 3. A second heat dissipation structure is provided, with a heat-conducting plate set in the base body and located at the upper and lower ends of the coolant chamber. Heat dissipation ridges are fixedly installed at equal angles at the top and bottom of the base body. The heat is evenly distributed from the base body to the heat dissipation ridges through the heat-conducting plate to avoid local overheating.

[0023] Furthermore, the raised strips increase the contact area with air, accelerating heat convection and thus improving heat dissipation efficiency.

[0024] Furthermore, the dual cooling structure of the first and second heat dissipation structures ensures that the heat generated by the grinding wheel can be dissipated in a timely and effective manner, thus guaranteeing the grinding quality of the product and the service life of the grinding wheel.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 The present invention provides the following technical solution:

[0034] Example 1: A self-sharpening wear-resistant resin grinding wheel includes a base 1, a first heat dissipation structure 3 and a second heat dissipation structure 4 installed inside the base 1, the first heat dissipation structure 3 being located inside the second heat dissipation structure 4, and a grinding tool 2 being fixedly installed on the outside of the base 1.

[0035] like Figure 1 , Figure 2 and Figures 4-6 As shown, a grinding tool 2 is mounted on the outer side of the substrate 1. The grinding tool 2 includes a transition layer 201, a working layer 202, a cavity 203, and a strip groove 204. The working layer 202 is provided on the outer side of the transition layer 201. The working layer 202 is provided on the outer side of the working layer 202 with an axially oriented equal-angle strip groove 204 and a cutting texture. Both the strip groove 204 and the cutting texture are set to be inclined clockwise at 45°. This design can enhance the friction and chip removal of the resin grinding wheel surface. At the same time, the fine strip groove 204 is also conducive to the dissipation of heat when the grinding tool 2 cuts the workpiece, thus improving the heat dissipation efficiency.

[0036] The grinding tool 2 consists of a transition layer 201 and a working layer 202 from the inside out. The abrasive concentration in the transition layer 201 is lower than that in the working layer 202, which makes the grinding tool 2 form a gradient abrasive layer. The working layer 202 has longitudinal equiangular pores 203, which are formed by the high-temperature decomposition of pore-forming agent (naphthalene or polymer) microspheres. Through the synergistic effect of the gradient abrasive layer and the porous structure, the passivated abrasive grains fall off in time, and new abrasive grains are exposed, thereby improving the self-sharpening performance. This structure adopts abrasive self-sharpening technology. With its special microstructure, it has isotropic mechanical properties at the macro level. After the abrasive grinding tool 2 becomes dull, the abrasive grinding tool 2 will undergo intergranular fracture under the action of load. The dulled microcrystalline particles fall off on their own, and new microcrystalline particles inside the abrasive grains are exposed and participate in grinding. The sharpness of the resin grinding wheel is effectively maintained, thereby realizing the self-sharpening of the grinding wheel.

[0037] Example 2: Figure 1 , Figure 5 and Figure 6 As shown, the first heat dissipation structure 3 includes a coolant chamber 301, a branch chamber 302, a first connecting pipe 303, a water pump 304, a second connecting pipe 305, and a valve 306. The coolant chamber 301 is located inside the base 1. The first connecting pipe 303 is fixedly connected to one end of the coolant chamber 301 away from the outer ring of the base 1. The water pump 304 is fixedly connected to one end of the first connecting pipe 303 away from the coolant chamber 301. The second connecting pipe 305 is fixedly connected to one end of the water pump 304 away from the first connecting pipe 303. A valve 306 is installed at the second connecting pipe 305, and two sets of water pumps 304 are designed. One end of the second connecting pipe 305 is connected to other pipes. When the valve 306 and the water pump 304 are opened, the hot water in the coolant chamber 301 is discharged. After the discharge is completed, the valve 306 and the water pump 304 are closed.

[0038] Connect the second connecting pipe 305 on the other side to the pipe of the cooling water tank, open the valve 306 and water pump 304 at this location, and pump the cooling water in the tank into the coolant chamber 301. The coolant chamber 301 is fixedly installed with branch chambers 302 at equal angles at one end near the outer ring of the base 1. Cooling water flows from the coolant chamber 301 into the branch chambers 302 respectively. The end of the branch chamber 302 away from the cooling water branch chamber 302 is set in the transition layer 201, so that the cooling water can easily absorb the heat generated by the grinding tool 2, making the heat absorption more uniform, thereby improving the heat dissipation efficiency and uniformity.

[0039] Example 3: Figure 2 and Figure 6As shown, the second heat dissipation structure 4 includes a heat-conducting plate 401 and a heat dissipation protrusion 402. The heat-conducting plate 401 and the heat dissipation protrusion 402 are respectively fixedly installed on the inner and outer sides of the base 1. The heat-conducting plate 401 is disposed inside the base 1 and is respectively disposed at the upper and lower ends of the coolant chamber 301. The heat dissipation protrusion 402 is fixedly installed at equal angles on the non-arc end of the outer side of the base 1. The heat-conducting plate 401 can evenly distribute the heat in the base 1 to the heat dissipation protrusion 402 to avoid local overheating. The heat dissipation protrusion 402 increases the contact area with air, accelerates heat convection, and quickly dissipates heat, thereby improving heat dissipation efficiency.

[0040] As described in Embodiments 2 and 3 above, the dual cooling structure of the first heat dissipation structure 3 and the second heat dissipation structure 4 ensures that the heat generated by the resin grinding wheel can be dissipated in a timely and effective manner, thus guaranteeing the grinding quality of the product and the service life of the resin grinding wheel.

[0041] Example 4: This self-sharpening wear-resistant resin grinding wheel utilizes a green abrasive and binder fusion technology, such as cubic boron nitride and diamond, offering advantages such as high efficiency, wear resistance, and zero pollution. Environmentally friendly binders, such as non-toxic and harmless resin binders, reduce environmental pollution. By rationally selecting and applying these materials, the wear resistance and other properties of the grinding wheel can be improved, while simultaneously reducing environmental harm.

[0042] The above completes the series of operations for the self-sharpening wear-resistant resin grinding wheel. Any content not described in detail in this instruction belongs to the prior art known to those skilled in the art.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
