Description

Technical Field

[0001] This utility model relates to the field of diamond technology, specifically to a horseshoe-shaped abrasive. Background Technology

[0002] In stone processing, high-speed rotating diamond grinding wheels are used to achieve surface leveling, rough grinding, fine grinding, and polishing of the stone. Chinese utility model patent (patent number CN221211324U) discloses a composite marble resin matrix, including a matrix and grinding wheels. The grinding wheel has a matrix and a diamond grinding wheel. The friction working surface of the matrix has multiple grooves, each groove containing a diamond grinding wheel. The friction working surface of the diamond grinding wheel is flush with the friction working surface of the matrix. Furthermore, the friction working surface of the matrix also has an arc-shaped groove extending from one side of the matrix to the other. The matrix forms a first grinding wheel section and a second grinding wheel section at the location of the arc-shaped groove.

[0003] The aforementioned patent employs a structure combining a substrate and diamond grinding wheels. While this can reduce wear on the substrate while ensuring cutting efficiency, the small area of ​​the arc-shaped groove results in poor flow guidance. Furthermore, the significant difference in processing area between the first and second grinding wheel sections easily leads to problems such as clogging, overheating, and workpiece burning, reducing work efficiency. Additionally, some materials may have impurities on their surface. If these impurities are not cleaned, the wear on the grinding disc will increase, causing the resin binder to heat up and soften, leading to diamond particle shedding or the grinding disc becoming brittle and cracking. This greatly reduces the practicality of the diamond grinding disc.

[0004] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a horseshoe-shaped abrasive with high flow guiding and heat dissipation capabilities, long service life, and high processing quality.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: A horseshoe-shaped abrasive tool includes a base and several horseshoe-shaped substrates connected to the base. The base has mounting holes for mounting the base on a machine tool. The side of the substrate facing away from the base is the friction working surface, with two diamond grinding strips symmetrically embedded on the friction working surface of the substrate. The two diamond grinding strips are arranged in a figure-eight shape on the substrate. The substrate protrudes upwards to form raised steps corresponding to the positions of the two diamond grinding strips. A guide groove is formed between the two raised steps and the substrate. The guide groove includes an opening section communicating with the mounting holes and an outlet section communicating with the outside. The cross-sectional area of ​​the opening section gradually decreases from the inside to the outside, and the cross-sectional area of ​​the outlet section gradually increases from the inside to the outside.

[0007] Furthermore, both diamond grinding bars extend from the opening section to the exit section, and the distance between the ends of the two diamond grinding bars near the mounting hole is less than the distance between the ends away from the mounting hole.

[0008] Furthermore, both of the raised steps are provided with grooves for embedding the diamond grinding strips. The diamond grinding strips are embedded in the grooves by means of bonding or bolting, and the friction working surface of the diamond grinding strips is higher than the friction working surface of the substrate.

[0009] Furthermore, both of the raised steps are provided with a number of positioning grooves, and each positioning groove is arranged along the periphery of the diamond grinding bar.

[0010] Furthermore, the base is provided with a positioning step for positioning the base at one end, and the opposite sides of the positioning step have a dovetail groove structure.

[0011] Furthermore, the width of the opening section is 1cm-3cm; the width of the outlet section is 1cm-7cm.

[0012] Furthermore, the diamond grinding wheel is made by blending diamond abrasive, modified resin, toughening agent and filler; the matrix is ​​made of nylon material or metal. By adopting the aforementioned design scheme, the beneficial effects of this utility model are as follows: by setting an opening section with a cross-sectional area that gradually decreases from the inside to the outside and an outlet section with a cross-sectional area that gradually increases from the inside to the outside, since the direction of the discharged chip material, airflow, or water flow is consistent when the chip material, airflow, or water flow comes out from the inside to the outside, the mutual influence between the opening section and the outlet section is already small, and the discharged chip material, airflow, or water flow remains stable, thereby fundamentally reducing or even eliminating the problem of matrix vibration, which is more conducive to the smooth discharge of grinding chips without accumulation.

[0013] Figure 1 This is a schematic diagram of the structure of this utility model; In the figure: 1. Matrix 11. Raised step 11. Positioning groove 111. Guide groove 12. Opening section 121. Outlet section 122. Positioning step 13. Diamond grinding wheel 2. Detailed Implementation

[0014] 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.

[0015] Reference Figure 1 : A horseshoe-shaped abrasive tool includes a disc-shaped base (not shown in the figure) and a plurality of horseshoe-shaped substrates 1 disposed on the base. The base is provided with mounting holes (not shown in the figure) for mounting the base on a machine tool. In this embodiment, the base is made of metal, plastic or nylon material; in addition, it is worth noting that the base with mounting holes is a commercially known device and will not be described in detail here.

[0016] For ease of description, the direction closest to the mounting hole is considered the inside, and the side of the base 1 facing away from the base is considered the friction working surface.

[0017] Two diamond grinding strips 2 are symmetrically embedded on the friction working surface of the substrate 1. Specifically, the diamond grinding strips 2 are made of a blend of diamond abrasive, auxiliary abrasive, nanoparticles and filler, which can improve the impact resistance of the diamond cutting head, making the grinding disc more suitable for construction in complex and harsh environments, and preventing the diamond from falling off prematurely due to the high strength of concrete. The tool life is longer than that of ordinary grinding discs.

[0018] The substrate 1 protrudes upwards at the positions corresponding to the two diamond grinding wheels 2 to form raised steps 11. A guide groove 12 is formed between the two raised steps 11 and the substrate 1. The guide groove 12 includes an opening section 121 communicating with the mounting hole and an outlet section 122 communicating with the outside. Both diamond grinding wheels 2 extend from the opening section 121 to the outlet section 122, and the distance between the ends of the two diamond grinding wheels 2 closest to the mounting hole is less than the distance between the ends furthest from the mounting hole. Preferably, the cross-sectional area of ​​the opening section 121 gradually decreases from the inside to the outside, and the cross-sectional area of ​​the outlet section 122 gradually increases from the inside to the outside. In this embodiment, the width of the opening section 121 is 1cm-3cm, and the width of the outlet section is 1cm-7cm. If the width of the guide groove 12 in this invention is too small, the chip removal performance will be reduced. If the width of the guide groove 12 is too large, the area occupied by each diamond grinding wheel 2 will be reduced accordingly, which will lead to insufficient grinding wheel life. Therefore, this invention sets the guide groove 12 with an appropriate width. On the one hand, it can reduce the weight of this invention, making the diamond grinding wheel lighter, lowering the cost, and improving work efficiency and energy utilization. On the other hand, it facilitates better heat dissipation, improves grinding performance, increases service life, reduces dressing frequency, and the overall performance is better than most commercially available grinding wheels. By setting an opening section with a gradually decreasing cross-sectional area from the inside to the outside and an outlet section with a gradually increasing cross-sectional area from the inside to the outside, the direction of the discharged chips, airflow, or waterflow at the junction of the opening section and the outlet section is consistent when the discharged chips, airflow, or waterflow comes out from the inside to the outside. The mutual influence is already small, and the discharged chips, airflow, or waterflow remains stable, thereby fundamentally reducing or even eliminating the problem of matrix vibration. At the same time, the guide groove 12 not only improves the flow rate of the guide groove 12, but also reduces the contact area between the diamond grinding wheel 2 and the grinding material. The guide groove 12 is conducive to airflow, improves the heat dissipation effect of the diamond grinding wheel, and has better heat dissipation, avoiding a large accumulation of heat, thereby improving the stability of the tool, extending the continuous grinding time of this utility model, and making it more conducive to the smooth discharge of grinding chips without accumulation.

[0019] Furthermore, the two diamond grinding wheels 2 are arranged in a figure-eight shape on the base 1. This invention, through research and design in cutting tool technology, addresses the issue that when the angle grinder operates at high speed, the outer circular linear velocity of the grinding disc is higher than the inner circular linear velocity. Therefore, according to the grinding principle, the outer circular diamond grinding wheel 2 experiences more wear. Thus, by designing the two diamond grinding wheels 2 in a figure-eight shape, the abrasive dust can be quickly discharged during high-speed rotation grinding, preventing clogging of the cutting tool's grinding surface, greatly improving grinding efficiency, reducing grinding temperature, and minimizing thermal damage to the diamond caused by grinding temperature.

[0020] Furthermore, each of the two raised steps 11 is provided with a positioning groove 111 for embedding the diamond grinding strip 2. The diamond grinding strip 2 is embedded in the positioning groove 111 by means of bonding or bolting, and the friction working surface of the diamond grinding strip 2 is higher than the friction working surface of the substrate 1. By providing a large number of positioning grooves 111 on the surface of the diamond grinding strip 2 in the utility model, the diamond grinding strip 2 can be accurately placed.

[0021] Furthermore, a positioning step 13 for positioning the base 1 is provided at one end near the base. The opposite sides of the positioning step 13 have a dovetail groove structure, which facilitates fixing it to the base. It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
