Description

Technical field

[0001] The utility model relates to the technical field of metal grinding, in particular to a rubber wheel for a sanding belt machine and a sanding belt machine using the rubber wheel for a sanding belt machine. [Background Technology]

[0002] Belt sanders are widely used in the metalworking industry for grinding, polishing, and deburring metal parts. Belt sanders offer a natural advantage, particularly for irregularly shaped parts, enabling efficient and precise machining. Therefore, belt sanders are often used for grinding residual risers in precision castings.

[0003] The rubber wheel (also known as the rubber contact wheel of the sanding belt machine) is the core component of the sanding belt machine. The standard hardness of rubber is between 40 and 95 degrees. The roughness requirement for residual riser grinding is relatively low. However, when material needs to be removed quickly, a high-hardness rubber wheel is usually selected to ensure durability and efficiency.

[0004] The abrasive grains coated on the belt, driven by the rubber wheel, form a "micro-edge cutting tool." Manual pressure is applied to the belt, forcing it into contact with the remaining riser to achieve the grinding process, a form of elastic grinding. When grinding with a new belt, the abrasive grains are sharp, allowing minimal pressure to be applied. However, as the belt ages, the grains become blunt, making grinding difficult even with high pressure. Due to the low efficiency and labor intensity of the process, it is generally discarded, yet approximately 30% of the abrasive grains still remain, resulting in significant waste.

[0005] To address the above issues, we provide a new technical solution. [Utility Model Content]

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a rubber wheel for a sanding machine, the technical solution of which is as follows:

[0007] A rubber wheel for a belt sander includes a rubber wheel body, the rubber wheel body including a hub and a rubber rim arranged on the outer periphery of the hub, a plurality of reinforcing fixing members are circumferentially arranged at intervals on the outer wheel surface of the rubber rim, the reinforcing fixing members are anchored into the outer wheel surface of the rubber rim and the outermost edge thereof does not exceed the outermost edge of the outer wheel surface of the rubber rim.

[0008] According to a rubber wheel for a belt sander according to an embodiment of the present invention, a plurality of grooves are circumferentially spaced apart on the outer wheel surface of the rubber wheel rim to form a circle of gear teeth on the circumference of the outer wheel surface; the reinforcing fixing piece is anchored to the gear teeth.

[0009] According to the rubber wheel of a sanding machine in an embodiment of the present invention, the reinforcing fixing member is an anchor nail.

[0010] According to a rubber wheel for a sanding machine in an embodiment of the present invention, the anchoring nails include a nail plate and a nail rod, the nail rod is anchored into the wheel teeth, and the nail plate is flush with the outer edge of the wheel teeth.

[0011] According to the rubber wheel for a belt sander in an embodiment of the present invention, a barb is provided on the nail rod.

[0012] According to a rubber wheel for a belt sander in an embodiment of the present invention, the number of reinforcing fixing members between two adjacent gear teeth is different, and the number of reinforcing fixing members between the spaced gear teeth is the same.

[0013] A sanding belt machine comprises the sanding belt machine rubber wheel described in any one of the above, wherein a sanding belt is provided on the sanding belt machine rubber wheel.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In the utility model, a plurality of reinforcing fixing members are circumferentially arranged at intervals on the outer wheel surface of the rubber rim of the rubber wheel body to improve the surface hardness of the rubber wheel. In this way, after the sanding belt is covered on the outside of the rubber wheel body, the passivated abrasive grains on the sanding belt can be further damaged, and the acute angles can be re-formed to restore the grinding function. In addition, the elastic deformation of the rubber wheel can be reduced, which is conducive to the passivated abrasive grains cutting into the metal material to perform "chip cutting" operations, thereby improving the abrasive grain utilization rate of the sanding belt. By changing the local hardness of the rubber wheel surface, the passivated abrasive grains on the sanding belt can be effectively fully utilized, thereby greatly reducing production costs, reducing the labor intensity of grinding workers and improving production efficiency.

The reinforcing fixing members are anchored into the outer wheel surface of the rubber rim 20 and their outermost edges do not exceed the outermost edge of the outer wheel surface of the rubber rim 20.

[0029] In the present invention, a plurality of reinforcing fixing members are circumferentially arranged at intervals on the outer wheel surface of the rubber rim 20 of the rubber wheel body 100 to improve the surface hardness of the rubber wheel. In this way, after the rubber wheel body 100 is covered with the sanding belt 110, the passivated abrasive grains on the sanding belt 110 can be further damaged, re-formed into acute angles, and the grinding function can be restored. In addition, the elastic deformation of the rubber wheel can be reduced, which is conducive to the passivated abrasive grains cutting into the metal material to perform "chip cutting" operations, thereby improving the abrasive grain utilization rate of the sanding belt 110.

[0030] Further, in some embodiments of the present utility model application, such as Figure 1 、 2 As shown in Figures 3 and 4, a plurality of grooves are circumferentially spaced apart on the outer surface of the rubber rim 20 to form a circle of gear teeth 30. The reinforcing fixing members, which are anchoring nails 40, are anchored into the gear teeth 30. In this embodiment, by driving the anchoring nails 40 into the gear teeth 30 of the rubber wheel, the surface hardness of the rubber wheel is improved, the utilization rate of the abrasive belt is increased from 70% to 100%, and the grinding value of the remaining 30% of dull sand grains is fully utilized, thereby reducing production costs.

[0031] Further, in some embodiments of the present utility model application, such as Figure 1 、 2 As shown in FIG. 3 , the anchoring nail 40 includes a nail plate 41 and a nail rod 42 . The nail rod 42 is anchored into the gear tooth 30 , and the nail plate 41 is flush with the outer edge of the gear tooth 30 .

[0032] Further, in some embodiments of the present utility model application, such as Figure 1 、 2 As shown in Figures 3 and 4, a barb 43 is provided on the nail rod 42, so that the anchor nail 40 can be firmly anchored on the gear teeth 30 of the rubber wheel, preventing the anchor nail 40 from loosening or falling off when the rubber wheel rotates at high speed.

[0033] Further, in some embodiments of the present utility model application, such as Figure 1 、 2 As shown in Figures 3 and 4, the number of reinforcing fixing members between two adjacent gear teeth 30 is different, and the number of reinforcing fixing members between the spaced gear teeth 30 is the same.
