[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0024] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0025] In order to solve the problem of poor applicability of the cutter wheel in the prior art, the present application provides a cutter wheel.

[0026] like Figure 1 and Figure 2As shown, the cutter wheel in the present application includes a cutter wheel body, the cutter wheel body has a mounting hole 10, and the mounting hole 10 is coaxially arranged with the axis of the cutter wheel body; the cutter wheel body also has a symmetrically arranged first cutting portion 20 and a second cutting portion 30, the first cutting portion 20 and the second cutting portion 30 have the same structure, and the first cutting portion 20 and the second cutting portion 30 are respectively located at the two ends of the axial direction of the cutter wheel body and are respectively arranged along the circumference of the cutter wheel body, the first cutting portion 20 and the second cutting portion 30 respectively extend from the middle of the cutter wheel body toward the outer periphery, so that the first cutting portion 20 and the second cutting portion 30 are close to each other and intersect at the outer periphery of the cutter wheel body, and the first cutting portion 20 includes a plurality of first blades 21 and a plurality of second blades 22 arranged in sequence and staggered along the circumference of the cutter wheel body, and there is an angle between adjacent first blades 21 and second blades 22.

[0027] When using the cutter wheel of the above structure, since the cutter wheel body has a mounting hole 10, the cutter wheel can be mounted and fixed to the cutter holder through the mounting hole 10. Furthermore, since the cutter wheel has a first cutting edge 21 and a second cutting edge 22, and adjacent first cutting edges 21 and second cutting edges 22 have an included angle, the cutter wheel can be used within a wider range of cutting pressures, thereby improving the cutting performance of the cutter wheel and enabling the cutter wheel of the present application to adapt to materials of varying thicknesses. Therefore, the cutter wheel of the present application effectively solves the problem of poor applicability of cutter wheels in the prior art.

[0028] Specifically, the second cutting portion 30 includes a plurality of third blades 31 and a plurality of fourth blades 32 that are sequentially staggered along the circumference of the cutter wheel body. The first blade 21 of the first cutting portion 20 and the third blade 31 of the second cutting portion 30 are symmetrically arranged and form a first angle. The second blade 22 of the first cutting portion 20 and the fourth blade 32 of the second cutting portion 30 are symmetrically arranged and form a second angle. The first angle is smaller than the second angle. By such an arrangement, it can be effectively ensured that the cutter wheel can adapt to processed materials of different thicknesses, thereby improving the applicability of the cutter wheel. Moreover, by such an arrangement, it can also be ensured that when the cutter wheel in the present application is used to process materials, the debris generated can be more easily discharged from both sides of the cutter wheel.

[0029] In a specific embodiment of the present application, the first angle is greater than or equal to 100 degrees and less than or equal to 160 degrees. Of course, it should be noted that in the present application, the second angle may change with the change of the first angle, or may not change with the change of the first angle, but it should be noted that the second angle is always greater than the first angle.

[0030] Specifically, the intersection of the first blade 21 and the third blade 31, as well as the intersection of the second blade 22 and the fourth blade 32, are sequentially connected to form the outer periphery of the cutter wheel body, which is circular. This arrangement effectively ensures the cutting performance of the cutter wheel, and when the cutter wheel is used to cut materials, it can ensure that the force applied to the cutter wheel is more stable, and enhance the use strength of the cutter wheel, making it less likely to be damaged, thereby extending the service life of the cutter wheel.

[0031] Optionally, the circular diameter is greater than or equal to 2 millimeters and less than or equal to 4 millimeters. Of course, when cutting a specific material, the circular diameter can also be appropriately adjusted so that the cutter wheel can cut the material more easily.

[0032] Optionally, the length of the mounting hole 10 is greater than or equal to 0.6 mm and less than or equal to 1 mm.

[0033] Optionally, the diameter of the mounting hole 10 is greater than or equal to 0.8 mm and less than or equal to 1.2 mm.

[0034] Specifically, the cutter wheel body further has a first disc surface 40 and a second disc surface 50 parallel to each other at both ends in the axial direction, and the first disc surface 40 is formed between the first cutting portion 20 and the mounting hole 10, and the second disc surface 50 is formed between the second cutting portion 30 and the mounting hole 10. This arrangement ensures that the tool holder can more easily fix the cutter wheel, thereby ensuring smooth operation of the cutter wheel when using the cutter wheel to cut the material.

[0035] Optionally, the outer edge of the first disc surface 40 is sharp-angled. This arrangement not only reduces the difficulty of processing the cutter wheel, but also makes it easier to discharge debris when the cutter wheel is used to cut the material, thereby reducing the risk of chip jamming and ensuring the performance of the cutter wheel.

[0036] Optionally, a chamfered surface is provided at the opening of the mounting hole 10. By such an arrangement, the cutter wheel can be mounted and fixed more easily.

[0037] Specifically, the first cutting portion 20 includes a plurality of first cutting surfaces 23 and a plurality of second cutting surfaces 24 arranged alternately in sequence along the circumference of the cutter wheel body. The first cutting surface 23 and the two adjacent second cutting surfaces 24 respectively form a first blade 21 and a second blade 22, and the adjacent first cutting surfaces 23 and second cutting surfaces 24 form a V-shaped surface. By such an arrangement, the contact area between the cutter wheel and the material being cut can be effectively increased, thereby reducing the pressure of the cutter wheel during processing, thereby making the cutting edge of the cutter wheel more durable and less prone to collapse. Correspondingly, a plurality of third cutting surfaces and a fourth cutting surface are provided on the second cutting portion 30, and the third cutting surface corresponds to the first cutting surface 23, and the fourth cutting surface corresponds to the second cutting surface 24.

[0038] In a specific embodiment of the present application, the first blade 21 and the second blade 22 are both straight lines. This arrangement can effectively reduce the difficulty of processing the cutter wheel.

[0039] In another specific embodiment of the present application, both the first blade 21 and the second blade 22 are curved. This arrangement maximizes the gap between the cutter wheel and the cutter holder, making it less likely for debris to accumulate and improving the performance of the cutter wheel. However, this increases the difficulty of manufacturing the cutter wheel.

[0040] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0041] 1. Effectively solve the problem of poor performance of the cutter wheel in the existing technology;

[0042] 2. Reduce the accumulation of debris on both sides of the cutter wheel and between the cutter wheel and the cutter holder;

[0043] 3. Simple structure and stable performance.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
