Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to an agglomerated abrasive wire product and a grinding tool. Background Technology

[0002] Agglomerated abrasive wires are tools used to improve the surface finish and precision of workpieces, and are widely used in machinery manufacturing, aerospace, automotive parts, and other fields. Their main function is to remove burrs, oxide layers, and other imperfections from the workpiece surface through friction between the abrasive wires and the workpiece, thereby achieving precise control of workpiece dimensions and improving surface quality.

[0003] During the grinding process, grinding debris easily adheres to the outer surface and between agglomerated abrasive particles, causing blunting of the abrasive's edges and clogging, thus reducing grinding quality. In actual grinding operations, a large amount of grinding debris is generated when the abrasive contacts the workpiece surface. This debris easily adheres between agglomerated abrasive particles, reducing the abrasive gap and affecting the abrasive's cutting performance. Furthermore, clogging also hinders heat dissipation during grinding, accelerating tool wear and reducing grinding quality and efficiency. Therefore, solving the clogging problem during grinding is crucial for improving the performance of agglomerated abrasive filament products. Utility Model Content

[0004] The main purpose of this invention is to provide an agglomerated abrasive wire product that avoids grinding debris adhering to the outer surface of the agglomerated abrasive and between the agglomerated abrasives.

[0005] To achieve the above objectives, the agglomerated abrasive wire product comprises:

[0007] The grinding layer is an integral structure with the mounting substrate layer; the grinding layer is provided with multiple abrasive substrates, each of which includes abrasive particles and a brittle media substrate, and the brittle media substrate and the abrasive particles are an integral structure.

[0026] Please see Figure 1 Agglomerated abrasive wire products include:

[0027] Install the base layer 10; and

[0028] The grinding layer is an integral structure with the mounting substrate layer 10. The grinding layer is provided with multiple abrasive substrates, each of which includes abrasive particles 20 and a brittle medium substrate 30. The brittle medium substrate 30 and the abrasive particles 20 are an integral structure.

[0029] In the technical solution of this utility model, since the abrasive particles 20 and the brittle medium matrix 30 are an integral structure, the brittle medium matrix 30 can break when the abrasive particles are subjected to pressure, thereby forming new voids in the abrasive particles, which helps to remove grinding debris, expose new abrasive, maintain the cutting performance of the abrasive, and improve grinding quality and efficiency.

[0030] Specifically, the mounting base layer 10 provides a fixed foundation for the grinding layer, preventing the grinding layer from becoming loose or falling off the mounting base layer 10. For example, part of the structure of the grinding layer can be embedded in the mounting base layer 10, or an adhesive can be applied to the surface of the mounting base layer 10 to fix the grinding layer to the mounting base layer 10, thus forming an integral fixed structure. It is understood that the cross-section of the mounting base layer 10 can be square, circular, etc., and is not limited here.

[0031] The abrasive layer acts on the surface of the workpiece to be processed, thereby reducing the surface roughness and improving the surface smoothness. To ensure the surface processing capability of the agglomerated abrasive filament products, the abrasive layer includes an integrally structured abrasive agglomerates 20 and a brittle media matrix 30. Specifically, when the abrasive agglomerates 20 exist in the form of a slurry, the brittle media matrix 30 is added to the abrasive agglomerate slurry. The brittle media matrix 30 can be added in the form of fragments, large particles, etc. Then, through processes such as stirring and shaking, the brittle media matrix 30 is mixed with the abrasive agglomerate 20 slurry. Then, through high temperature and high pressure treatment methods, the brittle media matrix 30 and the abrasive agglomerates 20 are integrated into a single structure, thereby ensuring the brittle media matrix 30... The connection strength between the abrasive particles 20 and the brittle medium matrix 30 is enhanced to prevent the brittle medium matrix 30 from detaching from the abrasive particles 20. When the agglomerated abrasive filament product proposed in this utility model is used to grind a workpiece, the brittle physical properties of the brittle medium matrix 30 are utilized. Under the reaction force of the workpiece, it is easy to break. Under the action of its own weight and friction, the detached brittle medium matrix 30 can detach from the mounting substrate layer 10 with abrasive particle debris, thereby preventing abrasive particle debris from adhering to the outer surface of the abrasive matrix and / or between the abrasive matrix, maintaining the cutting performance of the abrasive, and improving the grinding quality and efficiency. It is understood that the brittle medium matrix 30 can be a brittle material such as ceramic, glass, or quartz, and is not limited here. Furthermore, the brittle medium matrix 30 can be a shape with an arc surface, such as a sphere, hemisphere, or similar circular shape. In this way, when the abrasive matrix is ​​being ground, the problem of easy breakage of the brittle medium matrix 30 due to stress concentration caused by the presence of right angles, straight edges, or other structures is avoided.

[0032] In one embodiment of this utility model, the brittle medium matrix 30 is preferably glass. Glass material is low in cost and easy to form, making it suitable for large-scale production. At the same time, glass has corrosion resistance, which can ensure that the brittle medium matrix 30 is not corroded and loses its brittleness in some wet grinding or chemical environment scenarios.

[0033] Furthermore, the abrasive agglomerate 20 includes a first abrasive portion and a second abrasive portion. The first abrasive portion is located inside the brittle media matrix 30, and a portion of the structure of the second abrasive portion is exposed on the outer surface of the brittle media matrix 30. This structural design allows the agglomerated abrasive filament product to continue grinding the surface of the workpiece through the internal first abrasive portion after the second abrasive portion is consumed during the grinding process, thus extending the functional lifespan of the abrasive matrix. It is understood that the exposed portion of the second abrasive portion can be adaptively limited to the required exposure height through pressure, screening, or other methods.

[0034] In one embodiment of this utility model, the brittle medium matrix 30 has a cutting side surface and a grinding end surface. The second abrasive part is disposed close to the cutting side surface and the grinding end surface. During the grinding process, the end surface of the abrasive matrix mainly provides friction, while the side surface mainly provides cutting. These two areas are more likely to generate abrasive debris due to stress. Therefore, disposing the second abrasive part close to the cutting side surface and the grinding end surface helps to maintain the cutting and friction properties of the abrasive and improve the grinding quality and efficiency.

[0035] In one embodiment of this utility model, the mounting substrate layer 10 has an annular structure, and the abrasive substrate is arranged around the outer surface of the mounting substrate layer 10. In this way, the annular structure of the mounting substrate layer 10 makes the abrasive substrate evenly distributed in the circumference, avoiding excessive local wear, and is suitable for high-precision machining of cylindrical workpieces (such as bearings and shafts). At the same time, the annular structure of the mounting substrate layer 10 is easy to integrate with rotating tools (such as grinding wheel spindles) to improve grinding efficiency.

[0036] Furthermore, a heat dissipation gap is provided between every two adjacent abrasive substrates. The heat dissipation gap increases the surface area of ​​the agglomerated abrasive filament product, accelerates heat dissipation, prevents the substrate from softening or the abrasive from oxidizing and failing due to high temperature, and the heat dissipation gap helps to improve chip removal capacity, reduce the risk of clogging, and maintain the cleanliness of the grinding surface.

[0037] In one embodiment of this utility model, the mounting substrate layer 10 is a flexible structure. It is understood that the flexibility allows the flexible mounting substrate layer 10 to bend and deform to fit the surface of irregular workpieces (such as mold cavities, free-form surfaces), expanding the application scenarios. At the same time, the flexible structure of the mounting substrate layer 10 can absorb grinding impact vibration, reduce processing noise and improve surface finish. It is understood that the material of the mounting substrate layer 10 can be high-temperature resistant thermoplastic elastomer, high-temperature resistant nylon, and high-temperature resistant fiber fabric, etc., and is not limited here.

[0038] Preferably, the mounting substrate layer 10 is made of resin.

[0039] In one embodiment of this utility model, the abrasive agglomerates 20 are made of one or more of diamond, silicon carbide, corundum, and alumina. In one embodiment, by using a variety of materials, the agglomerated abrasive wire products can perform both coarse grinding and fine polishing (such as diamond + alumina), thereby improving processing efficiency.

[0040] This utility model also proposes a grinding tool, such as a grinding wheel or a grinding belt. The grinding tool includes the agglomerated abrasive filament product. The specific structure of the agglomerated abrasive filament product is as described in the above embodiments. Since the grinding tool proposed by this utility model adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0041] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
