Description

Technical Field

[0001] This utility model relates to abrasive wheel cutting discs, and more particularly to a heat-dissipating abrasive wheel cutting disc. Background Technology

[0002] Resin cutting discs use resin as a binder and fiberglass mesh as a support, combining various materials to achieve particularly outstanding cutting performance for difficult-to-cut materials such as alloy steel and stainless steel.

[0003] During the cutting process, high temperatures are generated due to high-speed rotation and friction between the cutting disc and the object. Because the resin matrix has extremely poor thermal conductivity, the heat is difficult to dissipate in time, causing the overall temperature of the cutting disc to rise. This not only accelerates resin aging but may also cause deformation or even cracking, affecting safety. Most common resin cutting discs are solid structures with no internal ventilation channels, relying solely on natural convection for heat dissipation, which is inefficient. Although some products have radial grooves on the surface to assist in chip removal, such structures cannot form a through-flow airflow and have limited improvement on the overall thermal balance.

[0004] Therefore, how to achieve heat dissipation for the entire cutting disc has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a heat dissipation type abrasive wheel cutting disc that incorporates a heat sink into the cutting disc body, thereby enhancing heat exchange between the inside and outside of the cutting disc body and effectively reducing the overall working temperature during the high-speed rotation of the cutting body.

[0006] To achieve the above objectives, the present invention provides the following technical solution: it includes a cutting disc body, the cutting disc body extending axially up and down, and an upper mounting cover and a lower mounting cover located on the front and rear sides of the cutting disc body. A heat sink is installed inside the cutting disc body, and an upper air guide groove is provided through the upper mounting cover and a lower air guide groove is provided through the lower mounting cover. Both the upper mounting cover and the lower mounting cover are detachably connected to the cutting disc body.

[0007] The present invention is further configured such that: the upper mounting cover protrudes downward with a mounting sleeve, and the lower mounting cover protrudes upward with a mating post that cooperates with the mounting sleeve; the heat sink is located inside the lower mounting cover and magnetically engages with the lower mounting cover; the heat sink is fitted with the mating post; the circumference of the mounting sleeve abuts against the inner wall of the mating post, and the top of the mating post abuts against the upper mounting cover.

[0008] The present invention is further configured such that: the mating column protrudes upward with a plurality of positioning rods, and each positioning rod is arranged at intervals along the circumference of the mounting sleeve; the upper mounting cover is provided with a positioning groove corresponding to each positioning column.

[0009] The present invention is further configured such that: heat dissipation ribs are provided at the top and bottom of the heat dissipation plate, and each heat dissipation rib is in the shape of a planar spiral and continuously surrounds the plate from the inside to the outside to form multiple concentric rings.

[0010] The present invention is further configured such that: both the upper mounting cover and the lower mounting cover are provided with a plurality of mounting plates along the circumference, and each mounting plate is detachably connected to the cutting disc body.

[0011] The present invention is further configured such that: the cutting disc body is provided with a mounting groove corresponding to each mounting plate, and the cutting disc body is provided with a positioning semicircle for inserting the corresponding mounting plate in each mounting groove.

[0012] The present invention is further configured such that: each mounting plate is provided with an insertion hole, and the cutting disc body is provided with a screw hole communicating with the insertion hole in each mounting groove.

[0013] By adopting the above technical solution, the heat sink located inside the cutting disc body can absorb and transfer the heat generated during the working process, and the outside air can form convection between the upper and lower air guide grooves, thereby improving its overall heat dissipation efficiency. In addition, since the upper and lower mounting covers are detachably connected to the cutting disc body, the overall service life of the grinding wheel cutting disc can be extended by replacing the worn cutting disc body or maintaining the heat sink.

Detailed Implementation

[0017] 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.

[0018] like Figures 1-5 As shown, this utility model discloses a heat-dissipating abrasive wheel cutting disc, including a cutting disc body 1, which extends vertically along its axial direction. It also includes an upper mounting cover 2 and a lower mounting cover 3 located on the front and rear sides of the cutting disc body 1. A heat dissipation plate 11 is installed inside the cutting disc body 1. An upper air guide groove 21 is provided through the upper mounting cover 2, and a lower air guide groove 31 is provided through the lower mounting cover 3. Both the upper mounting cover 2 and the lower mounting cover 3 are detachably connected to the cutting disc body 1 by bolts, magnets, or other means. The heat dissipation plate 11 inside the cutting disc body 1 can absorb and transfer the heat generated during operation, and external air can form convection between the upper air guide groove 21 and the lower air guide groove 31, thereby improving its overall heat dissipation efficiency. Furthermore, since the upper mounting cover 2 and the lower mounting cover 3 are detachably connected to the cutting disc body 1, the overall service life of the abrasive wheel cutting disc can be extended by replacing the worn cutting disc body 1 or maintaining the heat dissipation plate 11.

[0019] The upper mounting cover 2 has a downward-protruding mounting sleeve 22, while the lower mounting cover 3 has an upward-protruding mating post 32 that mates with the mounting sleeve 22. The heat sink 11 is located inside the lower mounting cover 3 and magnetically engages with it. The heat sink 11 is fitted with the mating post 32. The circumference of the mounting sleeve 22 abuts against the inner wall of the mating post 32, and the top of the mating post 32 abuts against the upper mounting cover 2. After the position of the heat sink 11 inside the lower mounting cover 3 is fixed, the mounting sleeve 22 of the upper mounting cover 2 abuts against the inner wall of the mating post 32, thus determining the axial position of the upper mounting cover 2 and the lower mounting cover 3. This facilitates the fixing of the upper mounting cover 2 and the lower mounting cover 3 to the cutting disc body 1, respectively.

[0020] The mating post 32 has several positioning rods 321 protruding upwards, and each positioning rod 321 is arranged at intervals along the circumference of the mounting sleeve 22. The upper mounting cover 2 is provided with a positioning groove 23 corresponding to each positioning post. During the process of the mounting sleeve 22 on the upper mounting cover 2 being inserted into the mating post 32 on the lower mounting cover 3, each positioning rod 321 will enter the corresponding positioning groove 23 on the upper mounting cover 2, thereby determining the radial position of the upper mounting cover 2 and the lower mounting cover 3. At this time, the upper and lower air guide grooves 31 can be aligned, allowing smooth air convection with the outside. Due to the action of each positioning rod 321, the two cannot rotate relative to each other, thus facilitating the fixation between the upper mounting cover 2 and the lower mounting cover 3.

[0021] The heat sink 11 is provided with heat dissipation ribs 111 at both the top and bottom. Each heat dissipation rib 111 is in the shape of a planar spiral and is formed by multiple concentric rings that are continuously wrapped around the radial side from the inside out. Since each heat dissipation rib 111 is in the shape of a flat spiral, it can effectively increase the heat dissipation area. In addition, it can cooperate with each air guide groove to realize gas convection and improve the overall heat dissipation efficiency of the cutting blade body 1.

[0022] Furthermore, both the upper mounting cover 2 and the lower mounting cover 3 are provided with a plurality of mounting plates 24 along the circumference. Each mounting plate 24 is detachably connected to the cutting disc body 1 by means of bolts, magnetic attraction, etc. Since each mounting plate 24 can be detachably connected to the cutting disc body 1, after the relative positions between the upper and lower mounting covers 3 are determined, the detachable connection between each mounting plate 24 and the cutting disc body 1 is then performed, thereby completing the fixation between the upper mounting cover 2, the lower mounting cover 3 and the cutting disc body 1. When the cutting disc body 1 needs to be replaced, it is not necessary to replace the entire assembly, thus reducing costs.

[0023] The cutting disc body 1 is provided with a mounting groove 12 corresponding to each mounting plate 24. The cutting disc body 1 is provided with a positioning semicircle 13 in each mounting groove 12 for inserting the corresponding mounting plate 24. After the mounting plates 24 of the upper mounting cover 2 and the lower mounting cover 3 are installed into the corresponding mounting grooves 12, the mounting plates 24 cannot move in the corresponding mounting grooves 12 due to the restriction of the positioning semicircle 13 in the corresponding mounting grooves 12, thus facilitating the installation of fasteners.

[0024] Each mounting plate 24 is provided with a socket 241, and the cutting disc body 1 is located in each mounting groove 12 and is provided with a screw hole 14 communicating with the socket 241. By inserting a bolt that matches the size of the screw hole 14 into each socket 241, the screw hole 14 is threadedly engaged with the corresponding screw hole 14, so as to achieve a firm and detachable connection between the mounting plate 24 and the cutting disc body 1. By rotating each bolt in the opposite direction, the upper mounting cover 2 and the lower mounting cover 3 can be separated from the cutting disc body 1.

[0025] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
