Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding disc technology, and in particular to a high-strength grinding disc. Background Technology
[0002] Grinding discs are commonly used grinding tools in industries such as machining and stone processing. During use, grinding discs need to withstand significant grinding and frictional forces, which requires them to possess high strength and wear resistance.
[0003] Traditional grinding discs are prone to cracking and peeling of the abrasive layer during high-speed rotation and high-load grinding. This not only affects the grinding effect but also results in a short service life of the grinding disc, requiring frequent replacement, which increases production costs and downtime. Utility Model Content
[0004] In view of the technical problems in the prior art, the abrasive layer of traditional grinding discs is prone to cracking and falling off during high-speed rotation and high-load grinding, which not only affects the grinding effect, but also leads to a short service life of the grinding disc, requiring frequent replacement, and increasing production costs and downtime, this utility model provides a high-strength grinding disc.
[0005] The technical solution adopted by this utility model is: a high-strength grinding disc, comprising a substrate and an abrasive disc, wherein the abrasive disc is mounted on one side surface of the substrate, and a reinforcing component for improving the strength of the abrasive disc is installed between the substrate and the abrasive disc. The reinforcing component includes reinforcing ribs and mounting grooves. The reinforcing ribs include linear reinforcing ribs and annular reinforcing ribs. The top of the reinforcing ribs is fixedly connected to the abrasive disc, and the bottom of the reinforcing ribs is fixedly connected to the substrate. The linear reinforcing ribs are arranged in a circular array with the center of the substrate as the origin, and the included angles between multiple linear reinforcing ribs are equal. Multiple annular reinforcing ribs are arranged in a concentric ring pattern and are interlaced with the linear reinforcing ribs. Through the interlaced circular array and concentric ring distribution structure of the linear and annular reinforcing ribs, the grinding force, friction force and other external forces borne by the grinding disc can be evenly distributed from multiple directions during use. This comprehensive stress dispersion mechanism effectively avoids stress concentration in local areas, significantly enhances the overall strength of the grinding disc, reduces the probability of cracks and damage, and extends the service life of the grinding disc.
[0006] Furthermore, the mounting groove is formed on one side surface of the abrasive sheet and the substrate, and fits into the reinforcing rib. The design of the mounting groove fitting into the reinforcing rib provides precise installation positioning for the reinforcing rib, ensuring that the reinforcing rib can be accurately installed in the predetermined position, and ensuring the integrity and stability of the reinforced component structure.
[0007] Furthermore, the substrate is made of aluminum alloy with a thickness of 1-3mm. Aluminum alloy has advantages such as low density, high strength, and corrosion resistance, which effectively reduces the overall weight of the grinding disc, requires less driving force, reduces equipment energy consumption, and helps improve the rotation speed and flexibility of the grinding disc.
[0008] Furthermore, the abrasive sheet has a thickness of 0.5-2mm, which can improve grinding efficiency and achieve efficient processing of various hard materials.
[0009] Furthermore, the height of the reinforcing rib is 0.3-1mm, and the width of the reinforcing rib is 0.1-0.5mm. The height of 0.3-1mm ensures that the reinforcing rib can effectively connect the substrate and the abrasive sheet, and transmit and disperse stress; the width of 0.1-0.5mm ensures that the reinforcing rib itself has sufficient strength and is not easily deformed or broken during the stress process.
[0010] Furthermore, the surface of the abrasive disc away from the substrate is provided with a wear-resistant coating, which is a tungsten carbide coating with a thickness of 0.05-0.2 mm. The tungsten carbide coating has extremely high hardness and excellent wear resistance. Applying this coating to the surface of the abrasive disc can form a strong protective barrier during the contact between the abrasive disc and the processed material, effectively reducing the wear on the surface of the abrasive disc.
[0011] Furthermore, the base has a mounting hole at its center, and the inner wall of the mounting hole has an internal thread. The internal thread design of the mounting hole allows for quick and secure installation and disassembly of the base and the equipment through a threaded connection, making it convenient for users to change grinding discs according to different processing needs and improving the efficiency and flexibility of the equipment.
[0012] Furthermore, a rubber washer is fixedly installed on the inner wall of the top of the mounting hole. The rubber washer can effectively buffer the impact force between the installation tool and the grinding disc, and can absorb the vibration generated by the rotation of the grinding disc, reduce the vibration transmitted to the equipment, reduce the vibration and noise of the equipment, and improve the operating stability and service life of the equipment.
[0013] The beneficial effects of this utility model are:
[0014] This invention utilizes a unique circumferential array and concentric ring distribution structure of interlaced linear and annular reinforcing ribs to evenly distribute grinding forces, frictional forces, and other external forces borne by the grinding disc from multiple directions during use. This comprehensive stress dispersion mechanism effectively avoids localized stress concentration, significantly enhances the overall strength of the grinding disc, reduces the probability of cracks and breakage, and extends its service life. It solves the problem of traditional grinding discs where the abrasive layer is prone to cracking and peeling during high-speed rotation and high-load grinding, which not only affects grinding performance but also leads to a short service life, frequent replacements, increased production costs, and downtime.

The reinforcing component 3 includes reinforcing ribs 301 and mounting grooves 302. The reinforcing ribs 301 include linear reinforcing ribs 3011 and annular reinforcing ribs 3012. The top of the reinforcing ribs 301 is fixedly connected to the abrasive disc 2, and the bottom of the reinforcing ribs 301 is fixedly connected to the substrate 1. The linear reinforcing ribs 3011 are arranged in a circular array with the center of the substrate 1 as the origin. The included angles between multiple linear reinforcing ribs 3011 are equal. Multiple annular reinforcing ribs 3012 are arranged in a concentric ring. The annular reinforcing ribs 3012 and the linear reinforcing ribs 3011 are interlaced and connected. Through the interlaced circular array and concentric ring distribution structure of the linear reinforcing ribs 3011 and the annular reinforcing ribs 3012, the grinding force, friction force and other external forces borne by the abrasive disc can be evenly distributed from multiple directions during the use of the abrasive disc. This comprehensive stress dispersion mechanism effectively avoids stress concentration in local areas, significantly enhances the overall strength of the grinding disc, reduces the probability of cracks and damage, and extends the service life of the grinding disc.
[0024] Reference Figures 1 to 3 As shown, the mounting groove 302 is formed on one side surface of the abrasive disc 2 and the substrate 1, and fits into the reinforcing rib 301.

The height of the reinforcing rib 301 is 0.3-1 mm, and the width of the reinforcing rib 301 is 0.1-0.5 mm. The surface of the abrasive disc 2 away from the substrate 1 is provided with a wear-resistant coating 4, which is a tungsten carbide coating with a thickness of 0.05-0.2 mm. The design of the mounting groove 302 matching the reinforcing rib 301 provides precise installation positioning for the reinforcing rib 301, ensuring that the reinforcing rib 301 can be accurately installed in the predetermined position, ensuring the integrity and stability of the reinforcing component 3 structure. Using tungsten carbide coating as wear-resistant coating 4 can provide extremely high hardness and excellent wear resistance. Applying this coating to the surface of the abrasive plate 2 can form a strong protective barrier during the contact between the abrasive plate 2 and the processed material, effectively reducing the wear on the surface of the abrasive plate 2.
