Description
Technical Field
[0001] The present invention relates to the technical field of saw blades, and in particular to a circular saw blade for processing grooves. Background Art
[0002] For example, publication number "CN119952155A" discloses "a carbide circular saw blade head structure that is easy to install and reusable," comprising a saw blade body, wherein the outer edge of the saw blade body is uniformly distributed with tooth-like protrusions, and two positioning grooves are provided on both sides of the upper portion of the tooth-like protrusions, and a partition wall is provided between the two positioning grooves. A baffle is fixed to the outer side of the partition wall for respectively pressing the two blades into the two positioning grooves. The two blades on each tooth-like protrusion have different thicknesses, and the blades are uniformly distributed with two or more identical cutting edges. However, in actual applications, the blade heads of this type of cutting saw blade will generate greater friction with the object being cut during the cutting process, which can easily produce cutting burrs, affect the cutting quality, and is not conducive to heat dissipation. Summary of the Invention
[0003] In response to the problems of poor cutting quality and poor heat dissipation in the prior art mentioned in the background technology, the present invention provides a circular saw blade for grooving, which can reduce burrs generated during the cutting process, improve heat dissipation, reduce the contact area with the cut product, and improve the accuracy of grooving.
[0004] To achieve the above objectives, the present invention adopts the following technical solutions.
[0005] A circular saw blade for processing grooves includes a tool body, a plurality of teeth are provided on the edge of the tool body, a tooth seat is provided on the teeth, a cutter head unit is connected to the tooth seat, and the cutter head unit is provided with a cutter head root and a cutter head top, the cross-section of the cutter head top is a conical structure, the cross-section of the cutter head root is a rectangular structure, the cross-section width of the teeth is smaller than the cross-section width of the cutter head unit, and the cutter head unit includes a cutter head side and a cutting surface arranged on both sides, and in the same radial direction, the thickness of the cutter head side close to the cutting surface is greater than the thickness of the cutter head side away from the cutting surface. In the present application, the cutter head unit is divided into a cutter head root and a cutter head top, and the cutter head root and the cutter head top are respectively set to different shapes, and the cutter head root with a quasi-rectangular structure ensures the connection area with the tooth seat, thereby improving the strength of the connection. At the same time, the cone-shaped cutter head top structure can improve the precision control of grooving and grooving, and facilitate chip removal and heat dissipation. Furthermore, in the present application, the tooth portion and the cross-sectional width are set to be smaller than the cross-sectional width of the cutter head unit, so that during the cutting process, only friction cutting occurs between the cutter head unit and the cut product, thereby avoiding friction contact between the tooth seat and the cut product, thereby improving the chip removal efficiency while ensuring the heat dissipation of the tooth seat, and reducing the probability of deformation of the cutter head unit due to excessively high processing temperature. Furthermore, in the present application, the cutter head unit It also includes a blade side and a cutting surface. The cutting surface is the side of the blade unit away from the tooth seat and is arranged in the same radial direction. The thickness of the blade side close to the cutting surface is greater than the thickness of the blade side away from the cutting surface. Therefore, during the cutting process, the blade unit only grooves the cut product through the cutting surface and the intersection line between the cutting surface and the blade side. Therefore, the blade side actually only contacts the cut product at the edge close to the cutting surface. The rest of the blade side can also provide good heat dissipation effect. At the same time, the main components of the blade unit are diamond and alloy, which have good thermal conductivity. Moreover, since the blade unit only contacts the cut product through the cutting surface, the cutting edge is reduced. Therefore, the generation of cutting burrs can be reduced during the cutting process, the sharpness of the cutting is ensured, and the cutting accuracy is improved.
[0006] Preferably, the cutter head unit includes an alloy layer connected to the tooth seat, and a diamond layer is connected to the side of the alloy layer away from the tooth seat. By combining the cutter head unit with the alloy layer and the diamond layer, effective cutting can be achieved through the diamond layer, while the alloy layer ensures a stable connection between the cutter head unit and the tooth seat.
[0007] Preferably, the cutter head unit includes a cutter head top surface, the cutter head top surface including a cutting tip distal to one end of the tooth holder, and an angle β formed between the cutter head top surface and a rotational tangent of the cutting tip. Setting the angle between the cutter head top surface and the rotational tangent of the cutting tip ensures that, during the cutting process, the cutter head top surface contacts the product only through the cutting tip, thereby reducing frictional resistance, improving the cutting sharpness of the cutting tip, and reducing burrs at the bottom of the groove. Furthermore, the heat dissipation effect of the cutter head top surface is ensured, and chip removal is improved, thereby resolving problems such as high resistance during the cutting process, high frictional heat, and poor cut surface texture.
[0008] Preferably, the cutter head unit includes a cutting surface, wherein the cutting surface includes a cutting tip at one end remote from the center of the cutter body, and an angle α is formed between the cutting surface and a centerline passing through the cutting tip. The cutter head unit includes a cutting surface, wherein the angle between the cutting surface and the centerline passing through the center of the circle of the cutting tip ensures the sharpness of the cutting tip, while also improving heat dissipation and chip removal, and can address issues such as high resistance during cutting, high frictional heat, and poor cutting surface texture.
[0009] Preferably, the tool body is provided with a tooth bottom circle between adjacent tooth seats, wherein the tooth bottom circle is an arc-shaped structure. The tooth bottom circle provided between adjacent tooth seats of the tool body can improve the chip holding effect.
[0010] Preferably, the tool body is provided with a plurality of silencer lines, each of which is arranged in a "Z" shape. Stress relief holes are provided at the ends of the silencer lines, and the stress relief holes are filled with an elastic medium. The silencer lines have the functions of heat dissipation and shock absorption. The silencer lines are evenly distributed on the tool body around the center of the tool body, and the number ranges from 3 to 8 groups. Stress relief holes are provided at both ends of the silencer lines. The main functions of the stress relief holes are to dissipate heat, reduce shock, and remove the cutting stress generated during the laser processing of the silencer lines, making the silencer lines more stable. The saw blade will not produce cracks, tearing, local deformation of the silencer line parts, and other abnormal conditions during use. The silencer lines and stress relief holes are filled with an elastic medium, generally vertically. After resin filling, they need to be flush with the disk surface of the tool body and must not be higher or recessed relative to the disk surface. The main function of the resin is to improve the damping characteristics of the saw blade during cutting through the resin's heat resistance and elasticity, so that the saw blade vibration during cutting is reduced, the vibration cycle is shortened, and the saw blade can become stable in a short time.
[0011] Preferably, the cutter body is provided with tooth bottom circles between adjacent tooth seats. The minimum gap between the silencer line and the tooth bottom circle is L, with a range of 8mm≤L≤10mm. The primary purpose of this distance is to allow heat generated by the saw blade during cutting to dissipate quickly through the silencer line and the resin inside, ensuring blade temperature stability during the cutting process.
[0012] Preferably, the cutter head unit includes a cutting surface, and the cutting surface is tilted along the axial direction of the tool body, and the cutting surface includes a high cutting edge and a low cutting edge on both sides, and the high cutting edges and the low cutting edges of adjacent cutter head units are staggered. The two sides of the cutting surface of the present application are set to different heights, thereby forming a high cutting edge and a low cutting edge, wherein during the cutting process, the high cutting edge will first contact the product to be cut, and due to the height difference between the high cutting edge and the low cutting edge, the cutting surface is tilted, which can ensure that the cutting angle at the high cutting edge is sharper, improve the cutting quality, and reduce the generation of burrs. Due to the tilted setting of the entire cutting surface, the high cutting edge on the tooth undertakes the main cutting task, and the remaining cutting surfaces are more convenient for heat dissipation. At the same time, due to the tilted setting of the cutting surface, the debris in the cutting process is more convenient to be guided and discharged by the cutting surface. Improve the efficiency of chip discharge. Since a single cutter head unit only processes one side of the groove, the ease of cutting is improved, thereby improving the processing efficiency. At the same time, the high-position cutting edge and the low-position cutting edge of adjacent cutter head units are staggered, thereby ensuring the uniformity of the left and right sides of the groove processing during the cutting process; at the same time, the chip discharge direction of adjacent cutting surfaces will be reversed, so that the chips can be evenly distributed throughout the entire cutting process. Preferably, the cutter head unit includes a cutter head top surface, the cutter head top surface includes a cutter tip away from the side of the tooth portion, the cutter tip and the high-position cutting edge are coplanar, and the cutter tip and the high-position cutting edge synchronously contact and cut the product. The blade tip is set to be coplanar with the high cutting edge, so that the blade tip can cut the product synchronously with the high cutting edge during the cutting process, so that the blade tip and the high cutting edge can form an "L"-shaped semi-enclosed cutting line during the cutting process, so that the debris can be guided and discharged along the cutting surface with the cutting line as the boundary, reducing the problem of debris getting stuck on the cutting line and affecting the cutting quality. At the same time, since the high cutting surface of the blade tip is coplanar, the inclination direction of the cutting surface will be tilted and offset toward the low cutting surface and toward the center of the tool body at the same time, that is, the guiding direction of the cutting surface is simultaneously toward the side away from the blade tip and the high cutting edge. In the actual cutting process, the debris can be moved toward the side away from the blade tip and the high cutting edge at the same time, thereby ensuring the cutting quality.
[0013] Preferably, the cutting surface is provided with an oblique guide groove, extending from the high-position cutting edge at the top of the cutter head to the low-position cutting edge at the base of the cutter head, with an opening provided on the low-position cutting edge. Providing the oblique guide groove improves guidance accuracy, directing the movement of chips closer to the direction from the high-position cutting edge at the top of the cutter head to the low-position cutting edge at the base of the cutter head. Furthermore, the oblique guide groove increases heat dissipation and chip removal area, and the opening increases chip removal efficiency. The side of the oblique guide groove away from the opening is not directly connected to the high-position cutting edge, thereby ensuring the structural strength of the high-position cutting edge and avoiding uneven cutting quality along the high-position cutting edge.
[0014] The beneficial effects of the present invention are as follows: (1) It can reduce the burrs generated during the cutting process, improve heat dissipation, reduce the contact area with the cut product, and improve the accuracy of the processing groove; (2) It can improve the cutting efficiency of the product while ensuring the uniformity of cutting, improve the efficiency and uniformity of debris discharge during the cutting process, and reduce the interference of debris on the tool during the cutting process.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0027] Example 1: like Figure 1 、 2 As shown in Figure 3, a circular saw blade for processing grooves includes a tool body 1, a plurality of teeth 2 are provided on the edge of the tool body 1, a tooth seat 21 is provided on the tooth portion 2, a cutter head unit 3 is connected to the tooth seat 21, a cutter head root 31 and a cutter head top 32 are provided on the cutter head unit 3, the cross-section of the cutter head top 32 is a conical structure, the cross-section of the cutter head root 31 is a rectangular structure, the cross-section width of the tooth portion 2 is smaller than the cross-section width of the cutter head unit 3, and the cutter head unit 3 includes a cutter head side surface 38 and a cutting surface 37 provided on both sides, and in the same radial direction, the thickness of the cutter head side surface 38 close to the cutting surface 37 is greater than the thickness of the cutter head side surface 38 away from the cutting surface 37.
[0028] In the present application, the cutter head unit 3 is divided into a cutter head root 31 and a cutter head top 32, and the cutter head root 31 and the cutter head top 32 are respectively set to different shapes, and then the cutter head root 31 with a quasi-rectangular structure ensures the connection area with the tooth seat 21, thereby improving the strength of the connection. At the same time, the cone-shaped cutter head top 32 structure can improve the precision control of grooving and grooving, and facilitate chip removal and heat dissipation. Furthermore, in the present application, the tooth portion 2 and the cross-sectional width are set to be smaller than the cross-sectional width of the cutter head unit 3, so that during the cutting process, only friction cutting occurs between the cutter head unit 3 and the cut product, thereby avoiding friction contact between the tooth seat 21 and the cut product, thereby improving the chip removal efficiency while ensuring the heat dissipation of the tooth seat 21, and reducing the probability of deformation of the cutter head unit 3 due to excessively high processing temperature. Furthermore, in the present application, the cutter head unit 3 also includes The cutter head side 38 and the cutting surface 37, the cutting surface 37 is the side of the cutter head unit 3 away from the tooth seat 21, and is arranged in the same radial direction, the thickness of the cutter head side 38 close to the cutting surface 37 is greater than the thickness of the cutter head side 38 away from the cutting surface 37, so that during the cutting process, the cutter head unit 3 only grooves the cut product through the cutting surface 37 and the intersection line between the cutting surface 37 and the cutter head side 38, so that the cutter head side 38 actually only contacts the cut product at the edge close to the cutting surface 37, and the rest of the position of the cutter head side 38 can also provide a good heat dissipation effect. At the same time, the main components of the cutter head unit 3 are diamond and alloy, which have a good thermal conductivity effect; and since the cutter head unit 3 only contacts the cut product through the cutting surface 37, the cutting edge is reduced, so the generation of cutting burrs can be reduced during the cutting process, the sharpness of the cutting is ensured, and the cutting accuracy is improved.
[0029] In this embodiment, tooth chamfers 22 are provided on the teeth 2. Chamfers 22 are provided on both the front and back surfaces of the saw blade, and are present on each tooth 2. Chamfers 22 are provided on both the left and right sides, and a tooth top surface 23 is provided at the intersection of the tooth chamfers 22 and the outer circumference. A transition line forms where the tooth chamfers 22 intersect the end face of the tool body 1. The transition line is formed by two intersecting surfaces that are not of the same square. The tooth chamfers 22 on either side form a certain acute angle, which is slightly greater than the required angle for slotting, approximately 3 to 5 degrees. This angle is used to resolve friction between the tooth 2 and the material and improve the quality of the cut surface 37.
[0030] like Figure 2 As shown, the cutter head unit 3 includes an alloy layer 33 connected to the tooth seat 21, and a diamond layer 34 is connected to the side of the alloy layer 33 away from the tooth seat 21. By combining the cutter head unit 3 with the alloy layer 33 and the diamond layer 34, effective cutting can be performed through the diamond layer 34, while the alloy layer 33 ensures the stability of the connection between the cutter head unit 3 and the tooth seat 21.
[0031] like Figure 2 、 6 As shown, the cutter head unit 3 includes a cutter head top surface 35, which includes a cutting tip 36 at one end away from the tooth seat 21. An angle β is formed between the cutter head top surface 35 and the rotation tangent of the cutting tip 36. The angle is set between the cutter head top surface 35 and the rotation tangent of the cutting tip 36 so that during the cutting process, the cutter head top surface 35 and the product are in contact only through the cutting tip 36, thereby reducing frictional resistance, improving the cutting sharpness of the cutting tip 36, and reducing burrs at the bottom of the groove. At the same time, the heat dissipation effect of the cutter head top surface 35 is ensured, and the chip removal effect is improved, which can solve the problems of high resistance during the cutting process, high friction heat, and poor texture of the cutting surface 37.
[0032] like Figure 4 、 6 As shown, the cutter head unit 3 includes a cutting surface 37, which includes a cutting tip 36 at one end away from the center of the cutter body 1. An angle α is formed between the cutting surface 37 and the centerline passing through the cutting tip 36. The cutter head unit 3 includes the cutting surface 37, wherein the angle between the cutting surface 37 and the centerline passing through the center of the circle of the cutting tip 36 ensures the sharpness of the cutting tip 36, while improving heat dissipation and chip removal, and can solve problems such as high resistance during the cutting process, high friction heat, and poor texture of the cutting surface 37.
[0033] like Figure 1 As shown, the tool body 1 is provided with tooth bottom circles 11 between adjacent tooth seats 21. The tooth bottom circles 11 are arc-shaped structures. The tooth bottom circles 11 provided between adjacent tooth seats 21 of the tool body 1 can improve the chip holding effect.
[0034] like Figure 1As shown, a plurality of silencer lines 12 are provided on the tool body 1 , each silencer line 12 is arranged in a “Z” shape, and a stress relief hole 121 is provided at the end of the silencer line 12 , and the stress relief hole 121 is filled with an elastic medium. The silencer line 12 has the function of heat dissipation and shock absorption. The silencer line 12 is evenly distributed on the tool body 1 around the center of the tool body 1, and the number ranges from 3 to 8 groups. Stress relief holes 121 are provided on both ends of the silencer line 12. The main function of the stress relief holes 121 is to dissipate heat, reduce shock and remove the cutting stress generated during the laser processing of the silencer line 12, so that the silencer line 12 is more stable, and the saw blade will not produce cracks, tearing, local deformation of the silencer line 12 and other abnormal conditions during use. The silencer line 12 and the stress relief holes 121 are filled with elastic medium, which is generally vertical. After the resin is filled, it needs to be flush with the disk surface of the tool body 1 and must not be higher or recessed relative to the disk surface. The main function of the resin is to improve the damping characteristics of the saw blade during cutting through the heat resistance and elasticity of the resin, so that the vibration of the saw blade during cutting is reduced, the vibration cycle is shortened, and the saw blade can become stable in a short time.
[0035] like Figure 6 As shown, the cutter body 1 is provided with tooth bottom circles 11 between adjacent tooth seats 21. The minimum gap between the silencer line 12 and the tooth bottom circle 11 is L, with a range of 8mm≤L≤10mm. The main purpose of this distance is to allow the heat generated by the saw blade during cutting to dissipate quickly through the silencer line 12 and the resin inside, ensuring temperature stability of the saw blade during the cutting process.
[0036] Example 2: like Figure 7 、 8As shown, the cutter head unit 3 includes a cutting surface 37, and the cutting surface 37 is tilted along the axial direction of the tool body 1. The cutting surface 37 includes a high cutting edge 371 and a low cutting edge 372 located on both sides. The high cutting edges 371 and the low cutting edges 372 of adjacent cutter head units 3 are staggered. The two sides of the cutting surface 37 of the present application are set to different heights, thereby forming a high cutting edge 371 and a low cutting edge 372. During the cutting process, the high cutting edge 371 will first contact the product to be cut. Due to the height difference between the high cutting edge 371 and the low cutting edge 372, the cutting surface 37 is tilted, which can ensure that the cutting angle at the high cutting edge 371 is sharper, improve the cutting quality, and reduce the generation of burrs. Due to the tilt of the entire cutting surface 37, the high cutting edge 371 on the tooth undertakes the main cutting task, while the remaining cutting surfaces 37 are more convenient for heat dissipation. At the same time, due to the tilt of the cutting surface 37 The oblique setting allows the debris in the cutting process to be more easily guided and discharged by the cutting surface 37, thereby improving the efficiency of debris discharge. Since a single cutter head unit 3 only processes one side of the groove, the ease of cutting is improved, thereby improving the processing efficiency. At the same time, the high-position cutting edge 371 and the low-position cutting edge 372 of the adjacent cutter head units 3 are staggered, thereby ensuring the uniformity of the groove processing on the left and right sides during the cutting process; at the same time, the chip discharge direction of the adjacent cutting surfaces 37 will be reversed, so that during the entire cutting process, the debris can be discharged evenly and intermittently toward both sides, avoiding the accumulation of debris on one side, while improving the efficiency of debris discharge.

The cross-sectional width of the teeth 2 is smaller than the cross-sectional width of the cutter head unit 3. The cutter head unit 3 includes cutter head side surfaces 38 and cutting surfaces 37 provided on both sides. In the same radial direction, the thickness of the cutter head side surface 38 close to the cutting surface 37 is greater than the thickness of the cutter head side surface 38 away from the cutting surface 37. The cutter head unit 3 includes an alloy layer 33 connected to the tooth seat 21. The side of the alloy layer 33 away from the tooth seat 21 is connected to a diamond layer 34. The cutter head unit 3 includes a cutter head top surface 35, which includes a cutting tip 36 at one end away from the tooth seat 21. An angle β is formed between the cutter head top surface 35 and the rotational tangent of the cutting tip 36. The cutter head unit 3 includes a cutting surface 37, which includes a cutting tip 36 at one end away from the center of the tool body 1. An angle α is formed between the cutting surface 37 and the centerline passing through the cutting tip 36. The tool body 1 is provided with a tooth bottom circle 11 between adjacent tooth seats 21. The tooth bottom circle 11 is an arc-shaped structure. The tool body 1 is provided with a plurality of muffler lines 12, each of which is arranged in a "Z" shape. The ends of the muffler lines 12 are provided with stress relief holes 121, which are filled with an elastic medium. The tool body 1 is provided with a tooth bottom circle 11 between adjacent tooth seats 21. The shortest gap between the muffler line 12 and the tooth bottom circle 11 is L, and 8mm≤L≤10mm.
[0038] By compounding the cutter head unit 3 into an alloy layer 33 and a diamond layer 34, effective cutting can be performed through the diamond layer 34, while the alloy layer 33 ensures the connection stability between the cutter head unit 3 and the tooth seat 21. An angle is set between the top surface 35 of the cutter head and the rotating tangent of the blade tip 36, so that during the cutting process, the top surface 35 of the cutter head and the product are in contact only through the blade tip 36, thereby reducing frictional resistance, improving the cutting sharpness of the blade tip 36, and reducing the generation of burrs at the bottom of the groove. At the same time, it can ensure the heat dissipation effect of the top surface 35 of the cutter head and improve the chip removal effect, which can solve the problems of high resistance in the cutting process, high friction heat, and poor texture of the cutting surface 37. The cutter head unit 3 includes a cutting surface 37, wherein there is an angle between the cutting surface 37 and the center line of the blade tip 36 passing through the center of the circle, which can ensure the sharpness of the blade tip 36, while improving the heat dissipation effect and chip removal effect, which can solve the problems of high resistance in the cutting process, high friction heat, and poor texture of the cutting surface 37. The tooth bottom circle 11 provided between adjacent tooth seats 21 of the tool body 1 can improve the chip holding effect. The muffler line 12 has the functions of heat dissipation and vibration reduction. The muffler lines 12 are evenly distributed on the tool body 1 around the center of the tool body 1, and the number varies from 3 to 8 groups. Stress relief holes 121 are provided on both ends of the muffler line 12. The main function of the stress relief holes 121 is to dissipate heat, reduce vibration, and remove the cutting stress generated during the laser processing of the muffler line 12, making the muffler line 12 more stable. The saw blade will not produce cracks, tearing, local deformation of the muffler line 12 during use. The interior of the muffler line 12 and the stress relief holes 121 are filled with elastic medium, which is generally vertical. After the resin is filled, it needs to be flush with the disk surface of the tool body 1 and must not be higher or recessed relative to the disk surface. The main function of the resin is to improve the damping characteristics of the saw blade during cutting through the resin's heat resistance and elasticity, so that the vibration of the saw blade during cutting is reduced, the vibration cycle is shortened, and the saw blade can become stable in a short time. The main purpose of this distance is to allow the heat generated by the saw blade during the cutting process to be quickly dissipated through the silencer line 12 and the resin inside, thereby ensuring the temperature stability of the saw blade during the cutting process.
[0039] Example 3: like Figure 9As shown, the cutter head unit 3 includes a cutter head top surface 35, and the cutter head top surface 35 includes a cutter tip 36 on the side away from the tooth portion 2. The cutter tip 36 and the high cutting edge 371 are coplanar, and the cutter tip 36 and the high cutting edge 371 synchronously contact and cut the product. The blade tip 36 is set to be coplanar with the high cutting edge 371, so that during the cutting process, the blade tip 36 can cut the product synchronously with the high cutting edge 371, so that during the cutting process, the blade tip 36 and the high cutting edge 371 can form an "L"-shaped semi-enclosed cutting line, so that the debris can be guided and discharged along the cutting surface 37 with the cutting line as the boundary, thereby reducing the problem of debris getting stuck on the cutting line and affecting the cutting quality. At the same time, since the blade tip 36 and the high cutting surface 37 are coplanar, the inclination direction of the cutting surface 37 is tilted and offset toward the low cutting surface 37 and toward the center side of the tool body 1, that is, the guiding direction of the cutting surface 37 is simultaneously toward the side away from the blade tip 36 and the high cutting edge 371, and in the actual cutting process, the debris can be moved toward the side away from the blade tip 36 and the high cutting edge 371 at the same time, thereby ensuring the cutting quality.
[0040] The cutter head unit 3 includes a cutting surface 37, and the cutting surface 37 is tilted along the axial direction of the tool body 1. The cutting surface 37 includes a high cutting edge 371 and a low cutting edge 372 on both sides. The high cutting edges 371 and the low cutting edges 372 of adjacent cutter head units 3 are staggered. The two sides of the cutting surface 37 of the present application are set to different heights, thereby forming a high cutting edge 371 and a low cutting edge 372. During the cutting process, the high cutting edge 371 will first contact the product to be cut. Due to the height difference between the high cutting edge 371 and the low cutting edge 372, the cutting surface 37 is tilted, which can ensure that the cutting angle at the high cutting edge 371 is sharper, improve the cutting quality, and reduce the generation of burrs. Due to the tilt of the entire cutting surface 37, the high cutting edge 371 on the tooth undertakes the main cutting task, while the remaining cutting surfaces 37 are more convenient for heat dissipation. At the same time, due to the tilt of the cutting surface 37 The oblique setting allows the debris in the cutting process to be more easily guided and discharged by the cutting surface 37, thereby improving the efficiency of debris discharge. Since a single cutter head unit 3 only processes one side of the groove, the ease of cutting is improved, thereby improving the processing efficiency. At the same time, the high-position cutting edge 371 and the low-position cutting edge 372 of the adjacent cutter head units 3 are staggered, thereby ensuring the uniformity of the groove processing on the left and right sides during the cutting process; at the same time, the chip discharge direction of the adjacent cutting surfaces 37 will be reversed, so that during the entire cutting process, the debris can be discharged evenly and intermittently toward both sides, avoiding the accumulation of debris on one side, while improving the efficiency of debris discharge.
[0041] Example 4: like Figure 10As shown, the cutting surface 37 is provided with an oblique guide groove 373, which extends from the high cutting edge 371 of the top 32 of the cutter head to the low cutting edge 372 of the base 31 of the cutter head. The oblique guide groove 373 is provided with an opening 374 on the low cutting edge 372. The provision of the oblique guide groove 373 can improve the guiding accuracy, so that the movement direction of the debris is closer to the direction from the high cutting edge 371 of the top 32 of the cutter head to the low cutting edge 372 of the base 31 of the cutter head. At the same time, the oblique guide groove 373 can increase the heat dissipation and chip removal area, and improve the chip removal efficiency through the opening 374. The side of the oblique guide groove 373 away from the opening 374 is not directly connected to the high cutting edge 371, thereby ensuring the structural strength of the high cutting edge 371 and avoiding uneven cutting quality of the high cutting edge 371.
[0042] The cutter head unit 3 includes a cutting surface 37, and the cutting surface 37 is tilted along the axial direction of the tool body 1. The cutting surface 37 includes a high cutting edge 371 and a low cutting edge 372 on both sides. The high cutting edges 371 and the low cutting edges 372 of adjacent cutter head units 3 are staggered. The two sides of the cutting surface 37 of the present application are set to different heights, thereby forming a high cutting edge 371 and a low cutting edge 372. During the cutting process, the high cutting edge 371 will first contact the product to be cut. Due to the height difference between the high cutting edge 371 and the low cutting edge 372, the cutting surface 37 is tilted, which can ensure that the cutting angle at the high cutting edge 371 is sharper, improve the cutting quality, and reduce the generation of burrs. Due to the tilt of the entire cutting surface 37, the high cutting edge 371 on the tooth undertakes the main cutting task, while the remaining cutting surfaces 37 are more convenient for heat dissipation. At the same time, due to the tilt of the cutting surface 37 The oblique setting allows the debris in the cutting process to be more easily guided and discharged by the cutting surface 37, thereby improving the efficiency of debris discharge. Since a single cutter head unit 3 only processes one side of the groove, the ease of cutting is improved, thereby improving the processing efficiency. At the same time, the high-position cutting edge 371 and the low-position cutting edge 372 of the adjacent cutter head units 3 are staggered, thereby ensuring the uniformity of the groove processing on the left and right sides during the cutting process; at the same time, the chip discharge direction of the adjacent cutting surfaces 37 will be reversed, so that during the entire cutting process, the debris can be discharged evenly and intermittently toward both sides, avoiding the accumulation of debris on one side, while improving the efficiency of debris discharge.
