Description

Technical Field

[0001] This utility model belongs to the field of diamond roller technology, and in particular relates to a heat-dissipating diamond roller. Background Technology

[0002] Diamond rollers are commonly used grinding tools. Their surfaces are inlaid with diamond particles, giving them high hardness, high wear resistance, and high precision. They are widely used in the precision machining of hard and brittle materials such as ceramics, glass, and cemented carbide. During use, the high-speed rotation and friction with the workpiece generate a significant amount of heat. If this heat is not dissipated promptly, the temperature of the diamond roller will rise, affecting its service life and machining accuracy.

[0003] Currently, most commercially available diamond rollers consist of a roller body and a grinding layer. The roller body is typically made of metal, while the grinding layer is composed of diamond particles and a binder. For example, Chinese patent CN214980286U discloses a diamond roller with improved heat dissipation. This roller includes a roller body with a grinding layer on its exterior. An internal mounting groove is located on one side of the grinding layer, and a support rod is fixedly connected inside the mounting groove. A pusher plate for accelerating airflow is located inside the support rod, and heat dissipation holes penetrating the roller body are also present inside the mounting groove. This patent improves heat dissipation efficiency by using a pusher plate to accelerate the airflow rate on the surface of the roller body, allowing hot air around the roller body to dissipate quickly.

[0004] Chinese patent CN207900943U discloses a diamond roller with improved heat dissipation performance, including a fixed ring, a support ring protruding from the outer wall of the fixed ring, a positioning ring connected to the end of the support ring away from the fixed ring, a grinding stone layer on the end of the positioning ring away from the support ring, and heat dissipation rings symmetrically arranged on the sidewalls of the support ring, with a plurality of heat dissipation fins evenly distributed on the heat dissipation rings. This patent increases the heat dissipation area and improves the heat dissipation effect by setting heat dissipation rings and heat dissipation fins on the sidewalls of the support ring.

[0005] Chinese patent CN117103126B discloses a disc-type diamond roller with an internal heat dissipation structure. Through the setting of the internal heat dissipation component, when the diamond roller generates heat during grinding operations, the controller of the grinding machine controls the electromagnetic block to repeatedly switch on and off, so that the internal cohesive heat bladder can be continuously squeezed and reset, and the heat guide strip can repeatedly extend outward and retract inward, so that the exposed part of the heat guide strip changes continuously. In this dynamic heat dissipation process, the heat inside the diamond roller can be effectively transferred and diffused outward.

[0006] However, existing diamond rollers still have some shortcomings in terms of heat dissipation. For example, some heat dissipation structures are complex, increasing manufacturing costs and maintenance difficulty. Some structures fail to fully utilize the heat dissipation potential of their internal space, resulting in limited heat dissipation effects. Other structures have poor stability and cannot meet the heat dissipation requirements under high-intensity, long-term working conditions. These problems cause diamond rollers to easily overheat under high-speed, high-load working conditions, which not only affects processing accuracy but also accelerates diamond particle shedding and wear, shortening the roller's service life.

[0032] like Figures 1 to 4 As shown,

[0033] A heat-dissipating diamond roller includes a roller body and a heat dissipation component;

[0034] The roller body includes a base 1 with a ring-shaped structure, a grinding part 2 with a ring-shaped structure arranged coaxially with the base 1, a diamond particle layer 3 disposed on the outer annular surface of the grinding part 2, and a mounting ring plate 4 connecting the base 1 and the grinding part 2. The mounting ring plate 4 is fixed to the grinding part 2 and to the base 1 by bolts. The area enclosed by the inner end face of the mounting ring plate 4, the outer wall of the base 1, and the inner wall of the grinding part 2 is a heat dissipation cavity. The volume of the heat dissipation cavity is determined according to the overall size of the roller, and it must meet the requirements of providing sufficient installation space and heat dissipation space without affecting the overall strength.

[0035] The base 1 is made of high-strength alloy material, which has good mechanical strength and wear resistance, and can withstand the centrifugal force generated during high-speed rotation and the impact force during the grinding process. The base 1 has a ring-shaped structure with mounting threads on its inner wall, which facilitates the installation of the rollers on the spindle of the grinding equipment. Threaded fixing holes 5 are evenly spaced along the circumference on one end side wall of the base 1. After installation, a fixing screw is inserted into the threaded fixing holes 5 for reinforcement, effectively preventing the equipment from vibrating and falling off over time. Multiple reinforcing ribs 6 are evenly spaced along the circumference on one end of the side wall of the base 1 located on the outer side wall of the mounting ring plate 4. The reinforcing ribs 6 can enhance the structural strength of the base 1 and prevent deformation during high-speed rotation.

[0036] The diamond particle layer 3 is composed of diamond particles and a metal binder. The diamond particles are evenly distributed on the annular outer surface of the grinding section 2 and are used to perform grinding on the workpiece.

[0037] The mounting ring plate 4 is provided with multiple ventilation holes 7 that communicate with the heat dissipation cavity; the ventilation holes 7 include multiple circular ventilation holes 8 distributed on the side of the mounting ring plate 4 near the outer circle and multiple waist-shaped ventilation holes 9 distributed on the side of the mounting ring plate 4 near the inner circle; the design of the ventilation holes 7 can effectively promote air circulation and enhance the heat dissipation effect.

[0038] The heat dissipation assembly is installed inside the heat dissipation cavity. The heat dissipation assembly includes a side ring plate 10 attached to the inner ring side wall of the grinding part 2, a side ring plate 21 attached to the outer side wall of the base 1 in the heat dissipation cavity area, and an annular fan blade 12 covering the side ring plate 10 and the side ring plate 211. The side ring plate 10 and the mounting ring plate 4, and the side ring plate 21 and the mounting ring plate 4 are all fixed with bolts to ensure that the heat dissipation assembly is firmly connected to the roller body. The side ring plate 10 and the side ring plate 211 are made of aluminum alloy material with good thermal conductivity, which can quickly absorb and conduct the heat generated during the grinding process.

[0039] The inner wall of the side ring plate 10 is provided with spiral guide vanes 13 arranged spirally along the axial direction. There are multiple spiral guide vanes 13, which are evenly distributed in the same spiral direction. When the roller rotates, the spiral guide vanes 13 can generate airflow guiding effect, promote the formation of directional airflow in the heat dissipation cavity, and improve heat dissipation efficiency.

[0040] The annular fan blade 12 includes an annular seat 14 fixed to the side annular plate 10 and the side annular plate 2 11 by bolts, and a plurality of inclined blades 15 arranged at equal intervals along the circumference on the annular seat 14; the annular seat 14 is made of lightweight and high-strength aluminum alloy material, and its diameter is adapted to the inner diameter of the heat dissipation cavity; the number of inclined blades 15 is 8 to 12, and the inclination angle is 25° to 35°; the inclined blades 15 can generate airflow when the roller rotates, accelerate the air flow, and quickly remove heat.

[0041] The working process of the heat-dissipating diamond roller of this utility model is as follows:

[0042] During operation, the heat-dissipating diamond roller contacts the workpiece for grinding. Part of the heat generated during grinding is conducted to the heat dissipation cavity through the side ring plate 10. The rotation of the roller drives the heat dissipation assembly to rotate together. The inclined blades 15 on the annular fan blade 12 generate airflow, which accelerates heat dissipation. At the same time, the spiral guide vane 13 guides the airflow in a specific direction to form a vortex, which accelerates the ventilation of the ventilation hole 7. The air exchanges with the outside air through the ventilation hole 7, carrying the heat out of the roller and achieving effective heat dissipation. The reinforcing rib 6 not only enhances the structural strength of the base 1, but also increases the heat dissipation area, further improving the heat dissipation effect.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
