[0023] The embodiments of this application are described in detail below. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0026] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0027] Please see Figure 1 and Figure 2 This application provides a cutting tool 100 for machining the surface of a product 200. The cutting tool 100 includes a handle 10 and a cutting head 20. The cutting head 20 is connected to one end of the handle 10, and the connection direction between the cutting head 20 and the handle 10 is a first direction X. The cutting head 20 includes a connecting portion 21 and a cutting portion 22 connected along the first direction X. The connecting portion 21 is used to connect to the handle 10. The cutting portion 22 protrudes from the connecting portion 21 and includes multiple cutting surfaces 221 and multiple cutting edges 222. The multiple cutting surfaces 221 are connected sequentially, and a cutting edge 222 is formed at the connection point of any two adjacent cutting surfaces 221. The multiple cutting edges 222 are symmetrically distributed along the center line AA of the cutting tool 100; wherein, a first included angle θ is formed between the cutting edge 222 and the center line AA of the cutting tool 100, where 0° < θ < 90°.
[0028] This application achieves a consistent surface tilt angle for the machined product 200 by symmetrically distributing multiple cutting edges 222 along the centerline AA of the tool 100 and forming a first angle θ between the cutting edges 222 and the centerline AA of the tool 100. This results in a smooth surface without burrs, significantly improving the overall yield of the product 200. Furthermore, the first angle θ between the cutting edges 222 and the centerline AA of the tool 100 eliminates the need to adjust the rotation angle of the tool 100 during the machining process, thus achieving a product 200 with a specific surface tilt angle. This design saves processing time, improves production efficiency, and solves the burr problem.
[0029] In this embodiment, the first included angle θ is 86.58°. In some other embodiments, the first included angle θ can be adjusted within the range of 0° to 90° depending on the actual situation.
[0030] In this embodiment, the orthographic projection of the connecting portion 21 along the first direction X is circular, and the diameter D of the circle is 40.6 mm. This design makes the diameter D of the cutting head 20 in this application larger than the diameter D of the end cutter commonly used in the prior art. At the same cutting speed Vc, the rotational speed n of the cutting tool 100 in this application is less than the rotational speed n of the end cutter. With a relatively lower rotational speed n, the entire machining process is more stable, and the surface of the machined product 200 is less prone to burrs and is smoother. For ease of understanding, Vc, D, and n satisfy the following relationship: Vc = (π × D × n) / 1000. In some other embodiments, the diameter D of the circle is not limited to 40.6 mm, and can be adjusted according to the actual situation to meet the requirements of this application.
[0031] In some embodiments, the number of cutting edges 221 is not less than two. The specific number of cutting edges 221 in this application can be adjusted according to actual conditions, as long as it meets the requirements of this application.
[0032] In some embodiments, the blade 221 is recessed inward toward the connecting portion 21.
[0033] In some implementations, the blade surface 221 is a plane.
[0034] In this embodiment, the cutting part 22 further includes a connecting surface 224 and an end face 223 facing away from each other. The connecting part 21 is connected to the connecting surface 224. The cutting surface 221 and the cutting edge 222 are respectively connected between the connecting surface 224 and the end face 223, and the end face 223 is located on the center line AA of the tool 100.
[0035] Please see Figures 2 to 4 In this embodiment, the cutting section 22 includes a first cutting face 2210, a second cutting face 2211, a third cutting face 2212, a fourth cutting face 2213, a fifth cutting face 2214, a sixth cutting face 2215, a seventh cutting face 2216, an eighth cutting face 2217, a ninth cutting face 2218, and a tenth cutting face 2219 connected in sequence. A first cutting edge 2220 is formed at the junction of the first cutting face 2210 and the second cutting face 2211; a second cutting edge 2221 is formed at the junction of the second cutting face 2211 and the third cutting face 2212; a third cutting edge 2222 is formed at the junction of the third cutting face 2212 and the fourth cutting face 2213; a fourth cutting edge 2223 is formed at the junction of the fourth cutting face 2213 and the fifth cutting face 2214; and a fifth cutting edge 2224 is formed at the junction of the fifth cutting face 2214 and the sixth cutting face 2215. The sixth cutting edge 2225 is formed at the junction of the sixth cutting edge 2215 and the seventh cutting edge 2216; the seventh cutting edge 2226 is formed at the junction of the seventh cutting edge 2216 and the eighth cutting edge 2217; the eighth cutting edge 2227 is formed at the junction of the eighth cutting edge 2217 and the ninth cutting edge 2218; the ninth cutting edge 2228 is formed at the junction of the ninth cutting edge 2218 and the tenth cutting edge 2219; and the tenth cutting edge 2229 is formed at the junction of the tenth cutting edge 2219 and the first cutting edge 2210.
[0036] In this embodiment, the first cutting edge 2220 and the sixth cutting edge 2225 are symmetrically distributed along the center line AA of the tool 100, the second cutting edge 2221 and the seventh cutting edge 2226 are symmetrically distributed along the center line AA of the tool 100, the third cutting edge 2222 and the eighth cutting edge 2227 are symmetrically distributed along the center line AA of the tool 100, the fourth cutting edge 2223 and the ninth cutting edge 2228 are symmetrically distributed along the center line AA of the tool 100, and the fifth cutting edge 2224 and the tenth cutting edge 2229 are symmetrically distributed along the center line AA of the tool 100.
[0037] Please see Figure 1One embodiment of this application provides a processing device (not shown), which includes a processing platform 300 and a cutting tool 100. A product 200 is placed on the processing platform 200. By adjusting the position of the processing platform 200 in the second direction Y, the center of the surface of the product 200 coincides with the center line AA of the cutting tool 100, wherein the second direction Y is perpendicular to the center line AA of the cutting tool 100. By using the cutting tool 100 of this application instead of a traditional end cutter, since the cutting tool 100 of this application has multiple cutting edges 222 symmetrically distributed along the center line AA of the cutting tool 100, and the cutting edges 222 form a first included angle θ with the center line AA of the cutting tool 100, this design can solve the problem that the traditional end cutter relies on the four-axis rotation accuracy to ensure the bevel angle of the product 200, resulting in a certain error in the bevel angle on both sides of the processed product 200. In addition, when a conventional end cutter processes the surface of the product 200, the product 200 needs to be tilted at a certain angle according to the actual situation, and the surface of the product 200 is prone to forming more burrs. The surface of the product 200 processed by this application has a consistent tilt angle and no burrs are generated. The surface of the product 200 is smooth, which greatly improves the overall yield of the product 200.
[0038] The aforementioned cutting tool 100, by setting multiple cutting edges 222 symmetrically distributed along the center line AA of the cutting tool 100, and forming a first included angle θ between the cutting edges 222 and the center line AA of the cutting tool 100, ensures that the tilt angle of the surface of the processed product 200 is consistent, and no burrs are generated, resulting in a smooth product surface and greatly improving the overall yield of the product 200.
[0039] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
