Description

Polishing Wheel for Elastic Coating Removal {GRINDING WHEEL}

The present invention relates to a polishing wheel for removing an elastic coating film, and more particularly, to the polishing of the surface of a building material, and more particularly, to an improved polishing wheel for removing an elastic coating film finished on a building.

Elastic coating refers to the finish of urethane, epoxy or paint on the floor or wall of a building for the purpose of waterproofing, flame retardant, antifouling or aesthetic finish.

The elastic coating film treated as described above may not be able to perform its function due to damage such as discoloration or peeling of the elastic coating film or cracking as time passes, and may also cause aesthetic damage.

As described above, in order to newly finish the damaged or worn elastic coating, the new elastic coating should be finished after removing the damaged or worn elastic coating.

As described above, in order to remove the damaged or worn elastic coating film, the grinding wheel is mounted on a hand grinder or a walking or traveling type grinding machine to rotate at high speed to remove the elastic coating film.

As shown in FIG. 6, the polishing wheel 1 to which the prior art for removing the elastic coating film is applied,

It is provided with a disk-shaped wheel body 3 having a mounting hole 2 for mounting to a tool in the center, and is substantially elastic on the bottom surface of the polishing flange 4 integrally formed at the edge of the wheel body 3. It is comprised by providing the grinding | polishing tip 5 irregularly for removing a coating film.

In the prior art as described above, the elastic coating film removed by the frictional heat generated when the polishing wheel is connected and rotated at high speed in order to remove the elastic coating film is fused to the polishing tip as well as the entire polishing wheel, thereby preventing smooth removal. do.

As the elastic coating film removed as described above is fused to the polishing wheel, the polishing wheel is formed in a disk shape, and the elastic coating film is connected in a plane state with the elastic coating film for removal so that the elastic coating film removed by the polishing tip is easily discharged to the outside of the polishing wheel. Because you can not.

In addition, since the polishing tip is simply irregularly attached to the polishing wheel, it is easily worn, and a considerable high heat is generated by direct friction with the elastic coating, and the elastic coating removed by the high temperature is fused to the polishing tip. Since the removed elastic coating film is not discharged to the outside of the polishing wheel, it is easy to remove the elastic coating film at first, but when heat is generated by friction, it is easily fused and impossible to remove. have.

Accordingly, the present invention is to solve the problems described above, the elastic coating film that is removed while improving the structure of the polishing wheel to be easily released heat generated during polishing is quickly released to the outside of the polishing wheel, removed Provides a polishing wheel that prevents the elastic coating from flowing back to the bottom of the polishing wheel and improves releasability, thereby preventing the removed elastic coating from sticking to the polishing wheel (fusion), thereby facilitating removal of the elastic coating film. The aim is to improve the life and quality of the wheel.

As described above, the abrasive wheel of the present invention can easily remove the elastic coating finished on the bottom or wall of the building while extending the life of the polishing wheel to enable users to reduce the cost and, of course, used as a finishing material for the building. It is an invention with many expected effects, such as being able to utilize various kinds of stones, as well as to polish the surface of wood.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention for achieving the above object.

Conventional grinding wheel 50 is mounted on a tool such as a hand grinder or grinding machine to facilitate the removal of the surface of the stone or wood as well as the elastic coating film.

In the present invention, it is possible to remove the elastic coating film more easily by improving the polishing wheel 50.

The polishing wheel 50 to which the technique of the present invention is applied has a truncated cone-shaped wheel body 52 having a fastening hole 51 so as to be mounted on a tool in the center of the upper surface, and the outer edge of the wheel body 52. There are several radially formed polishing flanges 53 integral with the wheel body 52.

The number of the polishing flanges 53 is formed to be at least three and to have a scattering space (S) that combines sufficient heat dissipation between the polishing flanges 53 to dissipate the elastic coating film removed with rapid heat dissipation during polishing. It should be less than 10 because it should be possible.

The inclined surface 54 of the wheel body 52 is formed with a plurality of heat dissipation holes 55 so that friction heat and dust generated during polishing are discharged.

The polishing flange 53 has a slanted blade 56 formed at the side of the rotational direction to prevent the protruding elastic coating film and the previously polished elastic coating film from entering the rear polishing flange 53 and scattering upward. do.

The blade 56 is formed to have an arc-shaped round (R) from the inner direction of the rotation direction to the outer direction so that the elastic coating film can be easily removed or scattered upward during the rotation process.

After heat-treating a large number of polishing tips 57 as a means for polishing and removing the elastic coating film on the bottom surface of the polishing flange 53, the heat generated during polishing by forming the coating layer 58 is the polishing flange 53. The resilient film to be removed while minimizing the transfer to the polishing flange 52 to prevent the phenomenon of sticking (fusion) to increase the releasability.

The coating material forming the coating layer 58 has a release property that prevents the removed elastic coating from sticking while minimizing thermal conductivity by using a material of Teflon, ceramic or glass system.

The polishing tip 57 preferably uses a diamond having a coarse size (more than 20 mesh), and the arrangement of the polishing tip 57 may be random, but in order to increase the efficiency of polishing, the inner side of the rotating direction may increase from the inner side. It is desirable to have an arc shape.

As described above, the polishing wheel 50 for removing the elastic coating film of the present invention is

After attaching to the tool through the fastening hole 51, the bottom surface of the polishing flange 53 is in contact with the surface to be polished and then operated to remove the elastic coating film while rotating the polishing wheel 50, causing friction with the elastic coating film. Done.

As the polishing wheel 50 rotates as described above, the polishing tip 57 fused to the bottom surface of the polishing flange 53 removes the elastic coating layer while frictionally contacting the elastic coating layer, and the heat generated in the process is the polishing tip. The coating layer 58 further formed on the outer surface of the 57 reduces the conduction to the polishing flange 53, thereby preventing the removed elastic coating from sticking to the polishing flange 53.

In addition, heat is also released to the outside through the heat dissipation hole 55 formed on the inclined surface 54 of the wheel body 52 to achieve efficient cooling.

In addition, in the process of being polished by the polishing tip 57, the polished elastic coating film is sent to the rear in the rotational direction and pressurized while meeting the scattering space S formed between the polishing flange 53 and the polishing flange 53. Since it is scattered upward while being escaped from being prevented from being re-introduced into the rear polishing flange 53, the removed elastic coating film is prevented from being fused to the polishing tip 57.

In addition, the blade 56 formed on the rotational side of the polishing flange 53 serves to primarily remove the elastic coating film in the polishing direction, as well as the elastic coating film removed by the front polishing flange 53. It is prevented from flowing into the bottom of the rear polishing flange 53.

That is, since the blade 56 is inclined to have a low rotational direction and a rearwardly high shape, the elastic coating film that is hit by the blade 56 while being rotated is scattered upward of the polishing wheel 50, so that the blade 56 is fused to the polishing tip 57. This can prevent the phenomenon.

The polishing wheel 50 of the present invention can be used to smoothly polish the surface of wood as well as various kinds of stone used as a building finishing material, as well as the removal of the elastic coating film that is commonly performed, of course, in the polishing process Damage and wear of the polishing tip 57 can be minimized to have a variety of advantages such as long life and high quality of the polishing wheel 50.
