[0017] Figure numerals: 1. tool handle; 2. tool body; 3. tool head; 4. cutting edge; 5. front side edge; 6. peripheral edge; 7. rear side edge; 8. chip groove; 9. annular transition surface. DETAILED DESCRIPTION

[0018] The following is combined with Figure 1 This application is described in further detail.

[0019] The embodiment of the present application discloses a T-shaped composite tool.

[0020] Reference Figure 1 The T-shaped composite tool comprises a handle 1, one end of which is fixedly connected to a blade 2, the end of which is away from the blade 2 and is provided with a chamfer, the end of which is away from the handle 1 and is fixedly connected to a cutter head 3, and the handle 1 and the blade 2 are integrally formed with the cutter head 3 in a T-shape. The cutter head 3, the handle 1 and the blade 2 are integrally formed with cemented carbide, and the cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, and the integral forming enhances the firmness and stability of the connection between the cutter head 3, the handle 1 and the blade 2. The cutter head 3, the handle 1 and the blade 2 are integrally provided with a titanium carbide coating, and the titanium carbide coating has the characteristics of being smooth, dense, high hardness, high temperature resistance, wear resistance, oxidation resistance and strong adhesion, thereby improving the service life of the T-shaped composite knife.

[0021] Reference Figure 1The cutter head 3 is provided with four evenly distributed cutting edges 4. Compared with the traditional two-edge cutting method, the four evenly distributed cutting edges 4 can make the cutting action more stable under high-speed rotation, reduce the vibration generated in the T-type composite tool, make the cutting more precise, and increase the processing efficiency. The four cutting edges 4 respectively include a front side edge 5 arranged at the end of the cutter head 3 away from the handle 1, the front side edge 5 is arranged in an inclined manner, and a peripheral edge 6 is arranged at the end of the front side edge 5 facing the handle 1. The peripheral edge 6 is provided on the side of the cutter head 3, and a rear side edge 7 is arranged at the end of the peripheral edge 6 facing the handle 1. The rear side edge 7 is arranged in an inclined manner. The front side edge 5, the peripheral edge 6 and the rear side edge 7 are connected to form a main cutting part.

[0022] Therefore, in the process of T-type composite tool cutting groove, the rear side edge 7 provides support force for the peripheral edge 6, reducing the possibility of peripheral edge 6 shaking during processing, solving the problem of poor groove width and position accuracy of existing T-type tool processing, and improving the stability and processing quality of cutting edge 4.

[0023] Reference Figure 1 The blade body 2 is provided with an annular transition surface 9. The connection between the blade head 3 and the blade body 2 can be provided with an arc chamfer according to actual conditions. The chamfer plays the role of arc transition, reducing the possibility of fracture between the blade head 3 and the blade body 2 due to stress concentration. The annular transition surface 9 is inclined from the blade head 3 to the shank 1, which reduces the interference of the blade body 2 on the subsequent processing surface while ensuring the rigidity of the tool. The annular transition surface 9 plays a transition role, reducing the risk of tool breakage due to stress concentration during T-type composite tool processing, and extending the service life of the tool.

[0024] Reference Figure 1 Four chip removal grooves 8 are provided on the outer peripheral wall of the blade body 2. The four chip removal grooves 8 are respectively located between the two cutting edges 4. The chip removal grooves 8 extend from the blade head 3 to the handle 1 along the central axis of the blade body 2. The chip removal grooves 8 are arranged parallel to the axis of the handle 1. Therefore, the chip removal grooves 8 arranged parallel to the axis of the blade body 2 enable the processing waste chips to be discharged in time and effectively, reduce the generation of surface processing lines, and effectively slow down the occurrence of chip blocking.

[0025] The implementation principle of the embodiment of the present application is: in the process of cutting grooves with a T-shaped composite tool, the rear side edge 7 provides support force for the peripheral edge 6, reducing the possibility of shaking of the peripheral edge 6 during processing, solving the problem of poor groove width and position accuracy in existing T-shaped tool processing, improving the stability of the cutting edge 4 processing, improving the processing efficiency and processing quality, and the chips generated after processing are discharged promptly and effectively along the chip groove 8, reducing the generation of surface processing lines, and effectively slowing down the occurrence of chip blockage.
