Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grinding wheel technology, specifically a cutting grinding wheel with strong impact resistance. Background Technology
[0002] Cutting grinding wheels play a vital role in supporting efficient production in various fields such as industrial manufacturing, construction, and metal processing in modern society. Whether it is the precise cutting of mechanical parts, the on-site cutting of construction steel, or the processing of metal components in automobile repair, cutting grinding wheels are indispensable. Their performance directly affects production efficiency and processing quality, and they have irreplaceable significance in promoting large-scale and refined production in various industries.
[0003] Meanwhile, a grinding wheel cutting disc with application number CN201820976531.8 includes a cutting disc body, an annular clamping plate, and a reinforcing plate. The cutting disc body has a central hole at its center, and the annular clamping plate has a through hole at its center. The outer edge of the annular clamping plate is connected to the wall of the central hole, and the wall of the through hole is raised outward from the cutting disc body. The included angle between the annular clamping plate and the cutting disc body is 10-80°. One end of the reinforcing plate is integrally cured with one side of the annular clamping plate by an adhesive. An annular groove is provided on the cutting disc body along the central hole, and the other end of the reinforcing plate is disposed in the annular groove. The outer surface of the other end of the reinforcing plate is lower than the surface of the cutting disc body.
[0004] However, the following problems were found in the implementation of the relevant technologies: Traditional cutting grinding wheels generally have insufficient impact resistance. When cutting high-hardness metal materials or encountering intermittent cutting scenarios, the grinding wheel is prone to chipping and breaking due to impact, which not only affects the cutting accuracy but may also cause safety accidents. At the same time, traditional grinding wheels have poor heat dissipation capacity. During long-term cutting operations, the heat generated by cutting cannot be dissipated in time, which will cause the abrasive working layer to wear faster, shorten its service life, and the high temperature may affect the material properties of the workpiece to be cut.
[0005] Therefore, we propose a cutting wheel with high impact resistance. Utility Model Content
[0006] To address the problems mentioned in the background art, this utility model provides a cutting abrasive wheel with strong impact resistance. With a steel core as the core support, the overall rigidity of the abrasive wheel body is improved through the synergistic effect of the upper and lower steel shells and reinforcing ribs. Furthermore, a specific filler is filled between the reinforcing ribs to absorb the vibration and impact energy generated during the cutting process.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a cutting grinding wheel with high impact resistance, comprising a grinding wheel body, the grinding wheel body comprising an inner steel core and an abrasive working layer located on the outer ring of the steel core, the steel core comprising upper and lower steel outer shells and a plurality of reinforcing ribs located between the two steel outer shells, the space between the plurality of reinforcing ribs being filled with filler, a central hole being provided at the center of the grinding wheel body, a conical clamping plate being provided on the central hole, a plurality of vertical plates being provided between the conical clamping plate and the grinding wheel body, and a reinforcing mesh being provided on the outer layer of the grinding wheel body.
[0008] Preferably, the steel core is made of a high-strength, high-rigidity metal.
[0009] Preferably, the reinforcing mesh is a glass fiber mesh.
[0010] Preferably, the filler is a polyurethane elastomer.
[0011] Preferably, the filler is located between multiple reinforcing ribs and in close contact with the upper and lower steel shells.
[0012] Preferably, the uprights are arranged at uniform intervals around the central hole.
[0013] Preferably, the upright plate is made of copper alloy.
[0014] Preferably, the grinding wheel body is covered with an easy-tear protective film when it leaves the factory.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a steel core as the core support. With the synergistic effect of the upper and lower steel shells and the reinforcing ribs, the overall rigidity of the grinding wheel body is greatly improved, effectively resisting the deformation force caused by high-speed rotation and cutting impact. This achieves the effect of enhancing structural stability and preventing the grinding wheel body from cracking due to insufficient rigidity. In addition, the filling between the reinforcing ribs with a specific filler can absorb the vibration and impact energy generated during the cutting process under the action of the filler's own elastic properties, and alleviate the instantaneous impact force on the abrasive working layer. This reduces the risk of the abrasive working layer cracking and improves the impact resistance of the grinding wheel.
[0016] 2. This utility model uses a copper alloy material to make the vertical plate. Due to the good thermal conductivity of copper alloy, the heat generated by the cutting of the abrasive working layer can be quickly conducted away, avoiding heat accumulation. This achieves the effects of effective heat dissipation, delaying the wear of the abrasive working layer, and extending the service life of the grinding wheel. Attached Figure Description

[0019] 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.
[0020] like Figures 1 to 4 As shown, this utility model provides a cutting abrasive wheel with high impact resistance, including a wheel body 1. The wheel body 1 includes an inner steel core 2 and an abrasive working layer 3 on the outer ring of the steel core 2. The steel core 2 provides core support for the wheel body, and the abrasive working layer 3 directly contacts the workpiece to complete the cutting action. The steel core 2 includes upper and lower steel shells 4 and several reinforcing ribs 5 located between the two steel shells 4. The upper and lower steel shells 4 form the basic frame of the steel core, and the reinforcing ribs 5 further enhance the structural strength of the steel core and prevent deformation. The spaces between the reinforcing ribs 5 are filled with filler material 6, which can fill the gaps between the reinforcing ribs and absorb the impact of cutting. Vibration and impact energy: The center of the grinding wheel body 1 is provided with a central hole 7 for connecting with external equipment to fix and drive the grinding wheel. A conical clamping plate 8 is provided on the central hole 7. The conical structure enhances the fit with the external equipment and improves the firmness of the grinding wheel fixation, preventing loosening during high-speed rotation. Several vertical plates 9 are provided between the conical clamping plate 8 and the grinding wheel body 1. The vertical plates 9 can balance the pressure of the conical clamping plate on the body and assist in the conduction of heat generated during cutting. The outer layer of the grinding wheel body 1 is provided with a reinforcing mesh 10, which wraps around the outer layer of the grinding wheel to enhance the tear resistance of the body and reduce the risk of chipping and breakage during cutting.
[0021] Specifically, the steel core 2 is made of high-strength, high-rigidity metal, which ensures that the steel core maintains structural stability under high-speed rotation and impact, and is not prone to deformation or breakage.
[0022] Furthermore, the reinforcing mesh 10 is specifically a glass fiber mesh, which has excellent toughness and tensile strength, and can more effectively improve the impact resistance and tear resistance of the outer layer of the grinding wheel.
[0023] Furthermore, filler 6 is specifically polyurethane elastomer. Polyurethane elastomer has excellent elasticity, which can maximize the absorption of cutting vibration and impact, while tightly combining with the steel shell and reinforcing ribs to improve the overall structural integrity.
[0024] It is worth noting that the filler 6 is located between multiple reinforcing ribs 5 and in close contact with the upper and lower steel shells 4.
[0025] It is worth noting that the vertical plates 9 are evenly spaced around the central hole 7.
[0026] It is worth mentioning that the upright plate 9 is made of copper alloy. Copper alloy has a high thermal conductivity, which can quickly conduct the heat generated by cutting, while also having a certain degree of toughness, which can help absorb minor impacts.
[0027] It is worth emphasizing that the outer layer of the grinding wheel body 1 is covered with an easy-tear protective film when it leaves the factory. The protective film can protect the abrasive working layer and the reinforcing mesh during transportation and storage, preventing them from being scratched or contaminated, and ensuring that the performance is intact when leaving the factory.
[0028] Among them, the "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.
[0029] Working Principle: During use, the external device, through the central hole 7 and the conical clamping plate 8, fixes the grinding wheel body 1. The vertical plates 9, evenly spaced around the grinding wheel body 1, balance the pressure during fixing, preventing uneven stress on the grinding wheel body 1. After starting the equipment, the grinding wheel body 1 rotates at high speed, and its outer abrasive working layer 3 directly contacts the workpiece to be cut, achieving the cutting action. The internal steel core 2 serves as the core support structure, and the upper and lower steel outer shells 4, along with the reinforcing ribs 5, collectively enhance the overall rigidity, preventing deformation of the grinding wheel body 1 under high-speed rotation and impact. The filler 6 between the reinforcing ribs 5 absorbs the vibration and impact energy generated during cutting, reducing the risk of cracking of the abrasive working layer 3. Simultaneously, the vertical plates 9, made of copper alloy, quickly conduct heat generated during cutting by the abrasive working layer 3, achieving heat dissipation. In addition, the reinforcing mesh 10 on the outer layer of the grinding wheel body 1 further wraps around it, enhancing the overall tear resistance; and when this device leaves the factory, the outer easy-tear protective film can prevent damage to the abrasive working layer 3 and the reinforcing mesh 10 during transportation and storage, which can be removed before use.
