Description

Technical Field

[0001] The utility model relates to the field of grinding rod components, in particular to a centerless grinding rod with high temperature resistance, high strength and long service life. Background Technique

[0002] In the traditional grinding process, due to the friction between the grinding rod and the grinding material, a large amount of heat is often generated. To prevent local overheating of the grinding rod, which may cause damage or reduce the grinding efficiency, traditional methods usually adopt water cooling or air cooling to dissipate the heat during grinding. However, these traditional methods have certain deficiencies. For example, during the heat dissipation process, the machine equipment needs to be stopped, and water cooling irrigation is carried out one by one for heat dissipation, which not only increases the inconvenience of operation, but also may affect the production efficiency and grinding quality.

[0034] The base material tube 2 and the metal tube 4 are fixed by heat-conducting adhesive and welding.

[0035] The base material tube 2 is fixed on one side of the mounting sleeve 1 and is the main body part of the entire grinding rod. The grinding tooth surface 3 is fixed on its outer side and is used to contact the material to be ground and perform grinding operations. The base material tube 2 needs to have good mechanical strength and heat resistance to withstand the stress and high-temperature environment during the grinding process. The grinding tooth surface 3 is arranged on the outer side of the base material tube 2 and is the surface where the actual grinding operation is carried out. The metal tube 4 is located inside the base material tube 2 and is fixedly connected with the base material tube 2 through heat-conducting adhesive and welding. The metal tube 4 not only plays a role in supporting and enhancing the structural strength but also serves as a heat-conducting channel to help conduct the heat generated during the grinding process.

[0036] At least four groups of the reserved groove 6 and the first screw hole 7 are opened.

[0037] The outer side wall of the fixing block 52 is in fitting contact with the reserved groove 6.

[0038] The reserved groove 6 and the first screw hole 7 are opened on the inner side of the metal tube 4 for installing and fixing the graphite tube 51 and its fixing block 52.

During operation, the grinding tooth surface 3 contacts the material to be ground and performs the grinding operation. Since a large amount of heat is generated during the grinding process, this heat is first conducted through the base material tube 2 to the metal tube 4. The metal tube 4 serves as a heat conduction channel to further conduct the heat to the graphite tube 51. With its excellent heat conduction performance, the graphite tube 51 quickly disperses and conducts the heat to the heat sink 54. The heat sink 54 dissipates the heat to the surrounding environment by increasing the heat dissipation area, thus ensuring the stable operation of the grinding rod in a high-temperature environment. Moreover, the wind generated during the high-speed rotation of the grinding also forms a natural air flow for the heat sink 54, further enhancing the heat dissipation effect. In addition, through the fixing methods of heat-conducting adhesive and welding, as well as the fastening method of bolt connection, the close connection and stable fixation between the components inside the grinding rod are ensured, improving the overall strength, durability of the grinding rod, and the convenience during installation and disassembly.
