[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] Reference below Figure 1-Figure 3 A cutting tool 100 according to an embodiment of the present utility model is described. The cutting tool 100 is used for processing a water pipe joint 30 .

[0027] like Figure 1-Figure 3 As shown, the tool 100 according to the embodiment of the present utility model comprises: a tool head 10 and a tool handle 20 .

[0028] The cutter head 10 and the handle 20 are connected; the cutter head 10 has a plurality of cutting edges 11, along the axial direction of the cutter 100 (ie Figure 1 The cutting edge 11 is located in the same plane at one end away from the tool handle 20, and the cutter head 10 also has a chip cutting edge forming surface 12, which is adjacent to the cutting edge 11 and located at one end of the cutting edge 11 close to the tool handle 20, and at least a portion of the chip cutting edge forming surface 12 is recessed toward the central axis of the cutter head 10.

[0029] Among them, the cutter head 10 and the handle 20 are connected and arranged. As some embodiments of the present application, the cutter head 10 and the handle 20 are constructed as an integrally formed part. The integrally formed part has good structural strength. By integrally forming the cutter head 10 and the handle 20, the connection reliability of the cutter head 10 and the handle 20 can be improved, and the probability of breakage at the connection between the cutter head 10 and the handle 20 can be reduced.

[0030] The cutter head 10 has a blade 11, and the number of the blades 11 can be multiple, and the number of the blades 11 can be but not limited to two, three, four, etc. As some embodiments of the present application, the number of the blades 11 is four. Figure 1The tool head 10 is provided with a plurality of blades 11, each of which has an end away from the tool handle 20 and an end close to the tool handle 20. The ends of the plurality of blades 11 away from the tool handle 20 are located in the same plane. The tool head 10 also has a chipping edge forming surface 12. The chipping edge forming surface 12 is adjacent to the blade 11. In other words, the chipping edge forming surface 12 is adjacent to and connected to the blade 11, and the chipping edge forming surface 12 is located at the end of the blade 11 close to the tool handle 20. At least part of the chipping edge forming surface 12 is recessed toward the central axis of the tool head 10. In other words, part of the chipping edge forming surface 12 is recessed toward the central axis of the tool head 10, or the entire chipping edge forming surface 12 is recessed toward the central axis of the tool head 10.

[0031] As some embodiments of the present application, the connection between the chip cutting edge forming surface 12 and the blade 11 is designed with a rounded corner, which can ensure a smooth transition between the connection between the chip cutting edge forming surface 12 and other blades 11 and ensure the strength of the blade 11.

[0032] As some embodiments of the present application, the bottom periphery of the tool 100 retains rounded corners. For example, the bottom periphery of the tool 100 retains a rounded corner with a radius of but not limited to 1 mm. Such a design can increase the structural strength of the tool 100, and such a setting can make the size of the bottom outer contour of the tool 100 the same as the size of the bottom outer contour of the water pipe connector 30, which facilitates the one-time processing of the water pipe connector 30 and allows the multiple curved surfaces of the water pipe connector 30 to be processed and formed in one time.

[0033] It should be noted that if Figure 3 As shown, by making at least a portion of the chip-cutting edge profile 12 concave toward the central axis of the cutter head 10, the tool 100 can be designed in strict accordance with the size and shape of the water pipe joint 30, so that the chip-cutting edge profile 12 is completely consistent with the outer contour of the water pipe joint 30. As some embodiments of the present application, by clamping the tool 100 on a CNC (Computer numerical control machine tools) machine tool, the detailed position of the water pipe joint 30 can be directly processed through the chip-cutting edge profile 12, and the water pipe joint 30 can be processed at one time.

[0034] Such an arrangement can reduce the processing difficulty of the water pipe joint 30 while ensuring the processing accuracy of the water pipe joint 30 , simplify the processing steps, and the tool 100 has lower requirements on the machine tool, which can also reduce the resource load of the machine tool and improve processing efficiency.

[0035] As some embodiments of the present application, the total length of the tool 100 may be, but not limited to, 150 mm, and the diameter of the tool 100 may be, but not limited to, 20 mm.

[0036] As some embodiments of the present application, the water pipe joint 30 can be directly processed on a device (such as a water cooling plate of a battery box) by using the tool 100 proposed in the present application.

[0037] Therefore, by providing a chip cutting edge forming surface 12 at one end of the blade 11 close to the blade handle 20, and making at least a portion of the chip cutting edge forming surface 12 recessed toward the central axis of the cutter head 10, the water pipe joint 30 can be directly processed on the device (such as the water cooling plate of the battery box), thereby reducing the processing difficulty of the water pipe joint 30, simplifying the processing steps, and improving the processing efficiency.

[0038] As some embodiments of the present application, by providing a chip-cutting edge forming surface 12 at one end of the blade 11 close to the handle 20, the angle and shape of the front end of the water pipe joint 30 can be directly processed.

[0039] In some embodiments of the present invention, Figure 1 As shown, the chip edge forming surface 12 includes a first portion 121 and a second portion 122, the first portion 121 is located between the second portion 122 and the blade 11, the first portion 121 is configured as a first fillet 1211, and the second portion 122 is configured to be aligned with the axial direction (i.e. Figure 1 The X direction shown in the figure has an inclined surface 1221 with an angle.

[0040] The chip edge forming surface 12 includes a first portion 121 and a second portion 122. Compared with the first portion 121 and the second portion 122, the first portion 121 is closer to the blade 11, and the first portion 121 is located between the second portion 122 and the blade 11. The first portion 121 is configured as a first fillet 1211, and the second portion 122 is configured as a first fillet 1211 with respect to the axial direction of the tool 100 (i.e. Figure 1 In other words, the second portion 122 is configured as a slope 1221, and the slope 1221 is at an angle to the axial direction of the tool 100 (ie, Figure 1 The X direction shown) has an angle.

[0041] The first portion 121 of the chip edge profile surface 12 is configured as a first rounded corner 1211, and the second portion 122 of the chip edge profile surface 12 is configured to be aligned with the axial direction of the tool 100 (i.e. Figure 1 The inclined surface 1221 with an angle (in the X direction shown in the figure) can make the first part 121 and the second part 122 of the chip edge forming surface 12 reasonably constructed, and can make the outer contour of the tool 100 completely match the outer contour of the water pipe joint 30, so that the detailed position of the water pipe joint 30 can be directly processed at one time by using a tool 100, which can reduce the processing difficulty of the water pipe joint 30, simplify the processing process, and improve the processing efficiency.

[0042] In some embodiments of the present invention, Figure 2 As shown, the radius of the first fillet 1211 is R1, satisfying the relationship: 2mm≤R1≤3mm.

[0043] The radius of the first fillet 1211 is R1, and R1 can satisfy the relationship: 2mm≤R1≤3mm, that is, the radius R1 of the first fillet 1211 can be any value between 2mm and 3mm, for example, the radius R1 of the first fillet 1211 can be but not limited to 2mm, 2.5mm, 3mm, etc. As some embodiments of the present application, the radius R1 of the first fillet 1211 can be 2.5mm.

[0044] By setting the radius R1 of the first fillet 1211 to any value between 2 mm and 3 mm, the size of the first fillet 1211 can be reasonably designed, and the size of the first fillet 1211 can be made to match the size of the water pipe connector 30, so that the outer contour of the first fillet 1211 can be made to match the outer contour of the water pipe connector 30, and the water pipe connector 30 can be processed at one time, thereby reducing the processing difficulty of the water pipe connector 30.

[0045] In some embodiments of the present invention, Figure 1 As shown, along the second portion 122 from one end close to the first portion 121 to the other end away from the first portion 121 , the inclined surface 1221 gradually extends toward the radial outer side of the tool 100 .

[0046] Among them, the second part 122 has two opposite ends, one end is close to the first part 121, and the other end is far away from the first part 121. Along the end of the second part 122 close to the first part 121 to the end of the second part 122 far away from the first part 121, the inclined surface 1221 gradually extends toward the radial outside of the tool 100, or it can be understood that along the end of the second part 122 close to the first part 121 to the end of the second part 122 far away from the first part 121, the inclined surface 1221 gradually moves away from the center axis of the tool head 10.

[0047] By gradually extending the inclined surface 1221 of the second portion 122 toward the radially outer side of the tool 100, the inclined surface 1221 can be designed reasonably, and the outer contour of the inclined surface 1221 can fit the outer contour of the water pipe joint 30, so that the water pipe joint 30 can be processed at one time, reducing the processing difficulty of the water pipe joint 30.

[0048] In some embodiments of the present invention, Figure 2 As shown, the inclined surface 1221 is aligned with the axial direction of the tool 100 (i.e. Figure 1 The included angle between the two directions (in the X direction shown) is α, which satisfies the relationship: 10 degrees ≤ α ≤ 20 degrees.

[0049] The inclined surface 1221 is aligned with the axis of the tool 100 (i.e. Figure 1 The angle between the inclined surface 1221 and the axial direction of the tool 100 (ie, the X direction) is α, and α can satisfy the relationship: 10 degrees ≤ α ≤ 20 degrees. Figure 1 The angle α between the inclined surface 1221 and the axial direction of the tool 100 (ie, the X direction) can be any value between 10 degrees and 20 degrees. Figure 1 The angle α between the inclined surface 1221 and the axial direction of the tool 100 (ie, the X direction shown in FIG. 1 ) may be, but is not limited to, 10 degrees, 15 degrees, 20 degrees, etc. As some embodiments of the present application, the inclined surface 1221 and the axial direction of the tool 100 (ie, the X direction shown in FIG. 1 ) may be, but is not limited to, 10 degrees, 15 degrees, Figure 1 The included angle α between the X direction shown in the figure can be 15 degrees.

[0050] By making the inclined surface 1221 and the axial direction of the tool 100 (i.e. Figure 1 The angle α between the inclined surface 1221 and the axial direction of the tool 100 (ie, the X direction) is any value between 10 degrees and 20 degrees, which can make the inclined surface 1221 and the axial direction of the tool 100 (ie, Figure 1 The angle between the inclined surface 1221 and the water pipe joint 30 is reasonably designed, so that the inclined surface 1221 fits the front end structure of the water pipe joint 30, and the outer contour of the inclined surface 1221 fits the outer contour of the water pipe joint 30. The water pipe joint 30 can be processed in one go, reducing the processing difficulty of the water pipe joint 30.

[0051] In some embodiments of the present invention, Figure 1 As shown, the cutter head 10 further has a plurality of chip removal grooves 13 , and along the circumferential direction of the tool 100 , the plurality of chip removal grooves 13 and the plurality of cutting edges 11 are alternately arranged in sequence.

[0052] The cutter head 10 further has a chip groove 13, and the number of the chip grooves 13 can be multiple, and the number of the chip grooves 13 can be but not limited to two, three, four, etc. As some embodiments of the present application, the number of the chip grooves 13 is four. Along the circumferential direction of the tool 100, the plurality of chip grooves 13 and the plurality of blades 11 are alternately arranged in sequence, which can be understood as, along the circumferential direction of the tool 100, each chip groove 13 is arranged between two blades 11, or each blade 11 is arranged between two chip grooves 13.

[0053] As some embodiments of the present application, from the end of the cutter head 10 away from the tool handle 20, one end of the chip groove 13 is located at the end of the cutter head 10 away from the tool handle 20, and along the axial direction of the tool 100 (i.e. Figure 1 The size of the chip groove 13 may be, but is not limited to, 20.70 mm.

[0054] By providing the cutter head 10 with a plurality of chip removal grooves 13 , the chips generated during machining by the tool 100 can be discharged smoothly, reducing the degree of chip accumulation, and reducing cutting force and cutting heat, which is beneficial to reducing the wear of the tool 100 and extending the service life of the tool 100 .

[0055] As some embodiments of the present application, Figure 1-Figure 3 As shown, both the cutting edge 11 and the chip flute 13 can be configured in a spiral shape.

[0056] In some embodiments of the present invention, Figure 1 As shown, the tool 100 further includes a plurality of chip removal extension grooves 14 . Along the axial direction, the plurality of chip removal extension grooves 14 are connected to the plurality of chip removal grooves 13 one by one and are all located at one end of the corresponding chip removal groove 13 close to the tool handle 20 .

[0057] The tool 100 further includes a plurality of chip removal extension grooves 14 extending along the axial direction of the tool 100 (i.e. Figure 1 The plurality of chip removal extension grooves 14 are connected and arranged in a one-to-one correspondence with the plurality of chip removal grooves 13, and the plurality of chip removal extension grooves 14 are all located at one end of the corresponding chip removal groove 13 close to the tool handle 20.

[0058] By making the tool 100 also include a plurality of chip removal extension grooves 14, and making the plurality of chip removal extension grooves 14 all located at the end of the corresponding chip removal groove 13 close to the tool handle 20, the chips generated during the processing of the tool 100 can be discharged along the chip removal groove 13 and then further discharged along the chip removal extension groove 14, so that the chips can be discharged more smoothly and the degree of chip accumulation can be reduced. In addition, such a setting can indirectly increase the size of the chip removal groove 13, which is conducive to reducing the cutting force and cutting heat, reducing the wear of the tool 100, and extending the service life of the tool 100.

[0059] In some embodiments of the present invention, the total volume of the plurality of chip removal grooves 13 is A times the volume of the corresponding entity structure, satisfying the relationship: 0.55≤A≤0.65.

[0060] The total volume of the plurality of chip removal grooves 13 is A times the volume of the corresponding entity structure, and A can satisfy the relationship: 0.55≤A≤0.65, that is, the total volume of the plurality of chip removal grooves 13 can be any value between 0.55 and 0.65 of the volume of the corresponding entity structure. For example, the total volume of the plurality of chip removal grooves 13 can be, but is not limited to, 0.55, 0.60, 0.65, etc. of the volume of the corresponding entity structure. As some embodiments of the present application, the total volume of the plurality of chip removal grooves 13 can be 0.6 of the volume of the corresponding entity structure.

[0061] By making the total volume of the plurality of chip removal grooves 13 any value between 0.55 and 0.65 of the volume of the corresponding entity structure, the volume of the chip removal groove 13 can be increased as much as possible within a reasonable range, which can further improve the chip removal function of the tool 100, reduce the degree of chip accumulation, reduce cutting force and cutting heat, and help reduce the wear of the tool 100 and reduce the replacement frequency of the tool 100. In addition, such a setting is conducive to increasing the rake angle design (making cutting easier).

[0062] In some embodiments of the present invention, the back angle of the blade 11 is β, which satisfies the relationship: 2 degrees ≤ β ≤ 4 degrees.

[0063] The clearance angle of the blade 11 is β, and β can satisfy the relationship: 2 degrees ≤ β ≤ 4 degrees, that is, the clearance angle β of the blade 11 can be any value between 2 degrees and 4 degrees. For example, the clearance angle β of the blade 11 can be but not limited to 2 degrees, 3 degrees, 4 degrees, etc. As some embodiments of the present application, the clearance angle β of the blade 11 is 3 degrees.

[0064] By setting the back angle β of the blade 11 to any value between 2 degrees and 4 degrees, the friction between the contact surface of the tool 100 and the workpiece can be reduced, thereby reducing the cutting force and the wear of the tool 100, which is conducive to extending the service life of the tool 100.

[0065] In some embodiments of the present invention, the wiper edge width of the blade 11 is B, which satisfies the relationship: 0.2 mm ≤ B ≤ 0.4 mm.

[0067] By setting the wiper edge width B of the blade 11 to any value between 0.2 mm and 0.4 mm, burrs generated during the machining process can be reduced or even eliminated, the finish of the machined surface can be improved, and the wear resistance of the tool 100 can be improved.
