DETAILED DESCRIPTION

[0026] 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.

[0027] Example

[0028] A tool for processing bimetallic materials, such as Figure 1 As shown, it includes a base 1 and a blade 5; the blade 5 is installed on the base 1; a plurality of chip grooves 9 are evenly spaced in the circumferential direction on the top of the base 1; the chip groove 9 is an arc-shaped structure and the arc of one side of the chip groove 9 is greater than the arc of the other side; a mounting groove 7 is provided on the base 1 on the side with a larger arc of the chip groove 9;

[0029] like Figures 2 to 3 As shown, the blade 5 is arranged in the mounting groove 7 and one side of the blade 5 abuts against the side wall of the mounting groove 7; a mounting hole 14 is arranged at the bottom of the mounting groove 7 on the base 1, and a connecting portion 13 matching the mounting hole 14 is arranged at the bottom of the blade 5; a positioning pin is fixedly connected to the middle part of the base 1 located in the mounting hole 14, and a positioning hole 3 matching the positioning pin is arranged in the middle part of the blade 5;

[0030] A clamping hole 11 is provided on the base 1 at the bottom of the mounting groove 7 and close to the mounting hole 14, and a clamping pin 12 is provided in the clamping hole 11, and the clamping pin 12 contacts the side wall of one side of the blade 5; a fixing screw hole 10 is provided on the side wall of the base 1, and the fixing screw hole 10 is connected to the mounting hole 14, and a fixing screw 6 is threadedly connected to the fixing screw hole 10.

[0031] Specifically, when in use, the blade 5 needs to be installed on the base 1 first. Figures 1 to 3 As shown, first insert the connection part 13 of the blade 5 into the mounting hole 14, and during the insertion process, the positioning column 4 will be inserted into the positioning hole 3. After the blade 5 is fully inserted, one side of the blade 5 contacts the side wall of the mounting groove 7, and at this time, the blade 5 is preliminarily positioned. Insert the clamping pin 12 into the clamping hole 11, wherein the clamping pin 12 is a structure of a large top and a small bottom. During the insertion of the clamping pin 12, the clamping pin 12 will gradually press against the blade 5 to further fix the blade 5. Install the fixing screw in the fixing screw hole 10, and the top of the fixing screw 6 will enter the mounting hole 14 and press the connection part 13 of the blade 5, thereby further fixing the blade 5. The blade 5 is fixed in combination by multiple methods, so that the blade 5 is not easy to loosen due to vibration during the cutting process. It should also be noted that the direction of rotation of the tool should ensure that the tool always turns from the side with a small arc of the chip groove 9 to the side with a large arc. The chip groove 9 on the side with a large arc can fully accommodate the cut debris and discharge it, thereby ensuring the processing effect. Furthermore, during the rotation of the cutter, the cutter will always abut against the side wall of the mounting groove 7, so that the cutter is not likely to get loose.

[0032] In a preferred embodiment, if Figures 1 to 4 As shown, the base 1 is a cylindrical structure, the bottom of the base 1 is fixedly connected to a base 20, the middle of the base 20 is fixedly connected to an intermediate portion 17, and the intermediate portion 17 is connected to a top cover 2. The top cover 2 is used to block the top opening of the base 1 to prevent debris from entering the inside of the base 1. The metal debris entering the inside of the base 1 is not easy to be discharged. During the rotation of the tool, the debris is easy to enter between the blade 5 and the workpiece, so that burrs and other problems are easy to occur on the surface of the workpiece.

Specifically, the water inlet hole 18 is connected to a cooling water supply pipeline, the cooling water supply pipeline is connected to a cooling water source, and the cooling chamber supply pipeline provides cooling water to the water inlet hole 18, and the cooling water enters the water tank 16 through the water diversion hole 19. The cooling water entering the water tank 16 can cool the tool as a whole. At the same time, the cooling water entering the water tank 16 will be discharged through the water outlet 8 and flush away the metal debris in the chip removal groove 9.

[0034] In a preferred embodiment, if Figures 1 to 4 As shown, a limiting groove 15 is provided on one side of the connecting portion 13 near the fixing screw 6. Through the design of the limiting groove 15, after the fixing screw 6 is turned in, the fixing screw 6 will be inserted into the limiting groove 15, and after the fixing screw 6 is inserted into the limiting groove 15, the connecting portion 13 cannot move up and down, thereby fixing the position of the blade 5.

[0035] In a preferred embodiment, if Figures 1 to 4 As shown, at least 10 blades 5 are provided. Specifically, in this embodiment, 11 blades 5 are provided. By increasing the number of blades 5 of the tool, the cutting rate can be increased, thereby improving the processing efficiency and reducing vibration and noise during processing.

The wiper blade 5 has high-precision cutting ability, which can ensure the precision and dimensional stability of the processed parts; the wiper blade 5 has a high cutting speed and feed speed during the cutting process, which can improve the processing efficiency and shorten the processing time; the wiper blade 5 has a small cutting force, which is not easy to cause tool wear, effectively prolongs the tool life and reduces the cost; the wiper blade 5 can be used for processing various materials, such as aluminum, stainless steel, copper, etc., and has good adaptability.

[0037] In a preferred embodiment, Figures 1 to 4 As shown, the blade 5 is made of high-speed steel, cemented carbide or ceramic cutting material. These materials have high hardness and high wear resistance, which can ensure that the blade 5 remains sharp and durable during high-speed cutting.
