It has good anti-corrosion, fire prevention, heat insulation and weather resistance. Color steel composite panel is usually composed of two layers of color coated steel plate and thermal insulation materials such as polyurethane and rock wool in the middle. Due to the multi-layer composite structure and high hardness of the material, traditional cutting heads have some obvious disadvantages in the cutting process of color steel composite panels. First, due to the high hardness of the surface steel plate of the color steel composite panel and the soft thermal insulation material in the middle, the blade of the traditional head is prone to offset during the cutting process, making it difficult to ensure the stability and accuracy of the processing. In addition, a large amount of chips will be generated during the cutting process. These chips accumulate on the processing surface, which not only affects the cutting effect, but also increases the wear rate of the blade. At the same time, the color steel composite panel will generate a lot of heat during the cutting process. If it is not cooled in time, it will affect the performance and life of the cutting head.

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description.

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0027] like Figures 1 to 4 As shown, the embodiment of the present invention provides a cutting tool head for color steel composite plate processing, including a tool rod 1, a blade 2, an anti-skid pad 3, a locking pressure block 4 and a coolant nozzle 5. The end of the tool rod 1 is provided with a first step groove 11 and a second step groove 12. The area of ​​the second step groove 12 is larger than the area of ​​the first step groove 11. The anti-skid pad 3 is located in the first step groove 11, and the anti-skid pad 3 is locked and connected to the tool rod 1 through a first locking bolt (not shown). The blade 2 is located in the second step groove 12. The locking pressure block 4 is connected to the tool rod 1 through a second locking bolt 61. A positioning hole 20 is provided in the middle of the blade 2. The locking pressure block 4 is provided with a The positioning column 41 is inserted into the positioning hole 20 to fix the blade 2 on the second step groove 12; the area of ​​the second step groove 12 is larger than the first step groove 11, which can provide more contact area to support the blade 2, thereby improving the installation stability of the blade 2; the locking pressure block 4 can fix the blade 2 on the second step groove 12 to prevent the blade 2 from shifting during the cutting process; the anti-slip pad 3 serves as a buffer layer between the blade 2 and the tool rod 1, which can effectively disperse the impact force generated during cutting, reduce the friction caused by the direct contact between the blade 2 and the tool rod 1, and prevent the blade 2 from sliding during the cutting process, thereby improving the installation stability of the blade 2 and reducing processing errors.

[0028] The blade 2 has a rectangular structure and is circumferentially provided with four mutually perpendicular, non-intersecting chip removal grooves 21 on its end surface. These chip removal grooves 21 are used to remove chips generated on the machined surface during cutting. In this embodiment, all four sharp edges of the blade 2 serve as cutting elements. The even distribution of the four chip removal grooves 21 around the circumference of the blade 2 allows the blade 2 to effectively remove chips when cutting in different directions, preventing chip accumulation from affecting the cutting effect on the machined surface.

[0029] The coolant nozzle 5 is disposed at the end of the tool bar 1. A coolant channel 10 is defined within the tool bar 1. The channel 10 is used to deliver cooling liquid to the coolant nozzle 5. The outlet of the coolant nozzle 5 is directed toward the blade 2 to direct the cooling liquid toward the blade 2. During the cutting process, the color-coated steel composite material rubs against the blade 2, generating a significant amount of heat. Spraying the cooling liquid onto the surface of the blade 2 through the coolant nozzle 5 quickly reduces the temperature in the cutting area, preventing overheating of the blade 2 that could affect its cutting performance, thereby extending the life of the tool head.

[0030] like Figure 1 and Figure 2As shown, further, the chip groove 21 has an arc-shaped structure, and the ratio of the length of the chip groove 21 to the length of the blade 2 is 0.5-0.75. This arrangement can ensure that the chip groove 21 has sufficient length to discharge chips, while avoiding the chip groove 21 being too long to affect the structural strength of the blade 2. In this embodiment, the ratio of the length of the chip groove 21 to the length of the blade 2 is 0.75; compared with the straight groove structure, the chip groove 21 with an arc structure can more smoothly guide the chips to be discharged naturally along the arc, thereby reducing the blockage and accumulation of chips in the chip groove 21.

[0031] Furthermore, the depth of the chip removal groove 21 is 2-6 mm. In this embodiment, the depth of the chip removal groove 21 is 46 mm. This configuration allows the chip removal groove 21 to have sufficient accommodation space to receive and discharge chips.

[0032] like Figure 3 As shown, further, a relief groove 40 is provided on the side of the locking block 4 close to the blade 2, and the relief groove 40 does not contact the blade 2. The provision of the relief groove 40 can provide a certain space around the blade 2, so that the chips generated by cutting will not accumulate between the locking block 4 and the blade 2, ensuring that the chips can be discharged smoothly.

[0033] Furthermore, the blade 2 is made of tungsten steel hard alloy. Tungsten steel hard alloy has extremely high hardness and wear resistance, and can maintain good cutting performance during long-term cutting.

[0034] Furthermore, the anti-skid pad 3 is made of rubber material. Rubber material has a high friction coefficient. The anti-skid pad 3 is made of rubber material, which can effectively prevent the blade 2 from sliding slightly during the cutting process, improve the installation structure stability of the blade 2, and thus improve the processing accuracy.

[0035] Furthermore, the surface of the blade 2 is coated with a titanium carbonitride coating. The low friction coefficient of the titanium carbonitride coating can reduce the frictional resistance between the blade 2 and the workpiece, making the blade 2 cut more smoothly during the cutting process, thereby improving the cutting efficiency and meeting the requirements for efficient processing of color-coated steel composite panels.

[0036] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
