Description

Technical Field

[0001] The utility model relates to the technical field of turning tools, in particular to a cutting groove of a hard alloy turning tool. Background Art

[0002] Carbide turning tools are tools used in horizontal lathes, turret lathes, automatic lathes and CNC lathes. Their working parts include blades, structures for breaking or rolling up chips, spaces for chip removal or storage, channels for cutting fluids and other structural elements. Carbide turning tools are widely used in cutting processes, especially for high-speed turning, precision turning and mass production turning.

[0003] The surface of the turning tool is generally provided with a chip breaker groove, the main function of which is to control and guide the flow and breaking of chips. During the cutting process, the chip breaker groove produces an additional deformation effect on the chips, which helps to control the curling and breaking of the chips, so that the chips are discharged in a predetermined direction and shape. This helps to maintain the surface quality of the workpiece, prevent the chips from being entangled on the tool or the workpiece, and thus improve work efficiency.

[0004] However, when most of the existing turning tools are processing workpieces, the waste chips generated by cutting will move along the chipping groove. Since the waste chips generated by the turning tool are mostly waste chip strips, the waste chip strips are easy to rub against the inner bottom wall of the chipping groove, causing serious wear on the inside of the chipping groove, thereby affecting the discharge of waste chips, resulting in a reduction in the service life of the turning tool. The staff needs to frequently replace the turning tool, which is too troublesome. Therefore, the utility model is proposed to solve the above problems. Utility Model Content

Since the waste chips generated by the turning tool are mostly waste chip strips, the waste chip strips are easily rubbed against the inner bottom wall of the cutting groove, causing serious internal wear of the cutting groove, thereby affecting the discharge of waste chips, resulting in a reduction in the service life of the turning tool, and requiring the staff to frequently replace the turning tool, which is too troublesome.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a carbide turning tool chipping groove, comprising a tool and a fixed seat, one end of the tool is in an I-shape, a fixing piece for fixing the tool on the fixed seat is arranged between the I-shaped end of the tool and the fixed seat, one end of the tool is a 55° tip angle tool, a chipping piece is arranged on the upper surface of the tool, and a heat sink for dissipating heat from the tool is arranged inside the tool.

[0007] Furthermore, the cutting piece includes a diamond block fixedly mounted on the upper surface of the tool, and the upper surface of the tool and both sides of the diamond block are provided with cutting grooves, and one end of the two cutting grooves overlap and present a diamond shape.

[0008] Furthermore, the heat sink includes a cavity opened inside the tool, one end of the cavity extends to the outside of the tool and is fixedly installed with a heat conductive block, and the upper surface of the heat conductive block and located directly below the two cutting grooves are fixedly installed with heat conductive columns extending to the outside of the tool.

[0009] Furthermore, one end of a plurality of the heat-conducting columns extends into the interior of the corresponding chipping groove, and the other end of a plurality of the heat-conducting columns is hemispherical.

[0010] Furthermore, the fixing part includes a first threaded hole opened on one end of the I-shaped tool, and a second threaded hole is opened on one side surface of the fixing seat. The diameter of the second threaded hole is the same as the diameter of the first threaded hole, and the inner wall of the second threaded hole and the inner wall of the first threaded hole are both provided with external threads.

[0011] Furthermore, a mounting bolt is threadedly inserted on the inner wall of the first threaded hole, and the other end of the mounting bolt is threadedly inserted into the second threaded hole and extends to the bottom of the tool. A nut is threadedly sleeved on the surface of the mounting bolt, and one side surface of the nut is in contact with the lower surface of the tool. One end of the I-shaped tool is movably mounted on the fixed seat by the mounting bolt and the nut.

[0012] Compared with the prior art, the utility model provides a cutting groove of a cemented carbide turning tool, which has the following beneficial effects:

[0013] The carbide turning tool chip breaking groove is provided with two chip breaking grooves on the upper surface of the tool by using a chip breaking piece, so that the chip breaking effect of the tool is stronger. By providing a heat dissipation piece, it is convenient to dissipate heat of the tool, so that the heat generated by the tool due to processing can be quickly transferred, thereby avoiding the phenomenon of local excessive temperature during tool processing. One end of a plurality of heat conducting columns is located inside the chip breaking groove, so that the inside of the chip breaking groove is uneven, thereby reducing the friction between the waste chip strip and the chip breaking groove, reducing the wear degree of the chip breaking groove, and extending the service life of the tool.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 and Figure 3 In this embodiment, a carbide turning tool chipping groove comprises a tool 1 and a fixed seat 2. One end of the tool 1 is in an I-shape. A fixing member for fixing the tool 1 on the fixed seat 2 is arranged between the I-shaped end of the tool 1 and the fixed seat 2. One end of the tool 1 is a 55° tool tip angle tool. A chipping member is arranged on the upper surface of the tool 1. A heat sink for dissipating heat from the tool 1 is arranged inside the tool 1.

[0021] See also Figure 1 and Figure 3 In this embodiment, the cutting piece includes a diamond block 3 fixedly mounted on the upper surface of the tool 1, and cutting grooves 4 are provided on the upper surface of the tool 1 and on both sides of the diamond block 3, and one end of the two cutting grooves 4 overlaps and presents a diamond shape.

[0022] See also Figure 1 , Figure 3 and Figure 4 In this embodiment, the heat sink includes a cavity opened inside the tool 1, one end of the cavity extends to the outside of the tool 1 and is fixedly installed with a heat conductive block 5, and the upper surface of the heat conductive block 5 and located directly below the two chipping grooves 4 are fixedly installed with heat conductive columns 6 extending to the outside of the tool 1, one end of several heat conductive columns 6 extends to the inside of the corresponding chipping grooves 4, and the other ends of several heat conductive columns 6 are hemispherical.

[0023] By arranging one end of a plurality of heat-conducting columns 6 inside the chipping groove 4, the inside of the chipping groove 4 becomes uneven, so that when the waste chip strip moves inside the chipping groove 4, the contact area between the waste chip strip and the inner bottom wall of the chipping groove 4 is reduced, thereby reducing the friction between the waste chip strip and the chipping groove 4, reducing the degree of wear of the chipping groove 4, and extending the service life of the tool 1.

[0024] It should be noted that when the tool 1 is processing, the temperature generated by the tool 1 can be quickly transferred to the heat conductive block 5, so that the heat conductive block 5 can quickly transfer the temperature, thereby avoiding the phenomenon of excessively high local temperature of the tool 1 during processing.

[0025] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the fixing member includes a first threaded hole 7 opened on one end of the I-shaped tool 1, and a second threaded hole 8 is opened on one side surface of the fixing seat 2. The diameter of the second threaded hole 8 is the same as the diameter of the first threaded hole 7. The inner wall of the second threaded hole 8 and the inner wall of the first threaded hole 7 are both provided with external threads. A mounting bolt 9 is threadedly inserted on the inner wall of the first threaded hole 7. The other end of the mounting bolt 9 is threadedly inserted through the second threaded hole 8 and extends to the bottom of the tool 1. A nut 10 is threadedly sleeved on the surface of the mounting bolt 9. One side surface of the nut 10 contacts the lower surface of the tool 1. One end of the I-shaped tool 1 is movably mounted on the fixing seat 2 through the mounting bolt 9 and the nut 10.

[0026] Since most of the tools 1 and the fixing seat 2 are integrated, when the tool 1 is damaged, the staff will replace the fixing seat 2 together with the tool 1, which easily wastes a lot of materials. By setting the mounting bolts 9 and the nuts 10, the tool 1 and the fixing seat 2 are separated. When the tool 1 is damaged, the staff only needs to replace the tool 1, thereby reducing the cost expenditure.

[0027] The working principle of the above embodiment is: by setting one end of a plurality of heat-conducting columns 6 inside the chipping groove 4, the inside of the chipping groove 4 is made uneven, so that when the waste chip bar moves inside the chipping groove 4, the contact area between the waste chip bar and the inner bottom wall of the chipping groove 4 is reduced, thereby reducing the friction between the waste chip bar and the chipping groove 4, reducing the wear degree of the chipping groove 4, and extending the service life of the tool 1.
