Description

Technical Field

[0001] This utility model relates to the field of machining tool technology, and in particular to an aluminum alloy machining tool. Background Technology

[0002] Cutting tools are tools used for cutting and machining in mechanical manufacturing. The vast majority of cutting tools are machine-made, but some are hand-operated. Since cutting tools used in mechanical manufacturing are primarily for cutting metal materials, the term "cutting tool" is generally understood as a metal cutting tool. Tools used for cutting wood are called woodworking tools. There is also a special category of cutting tools used in geological exploration, well drilling, and mining; these are called mining tools.

[0003] When cutting aluminum alloys with machining tools, due to the high viscosity of aluminum alloys, chips tend to adhere to the cutting edge and rake face of the tool during long-term cutting, forming built-up edge. Built-up edge changes the shape of the cutting edge, leading to unstable cutting force, affecting machining accuracy and surface roughness. In addition, after the built-up edge falls off, it may scratch the machined surface. In severe cases, aluminum alloy material may also stick to the tool, making it impossible for the tool to cut normally. Therefore, this application proposes an aluminum alloy machining tool. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the background technology that, due to the high viscosity of aluminum alloys, chips easily adhere to the cutting edge and rake face of the cutting tool during long-term cutting, forming built-up edge, which affects machining accuracy and surface roughness, and hinders normal cutting. The invention proposes an aluminum alloy machining tool.

[0005] The technical solution of this utility model is as follows: An aluminum alloy machining tool, comprising a tool body, the tool body including an integrally formed mounting part and a cutting part, and further comprising:

[0006] A fixing cover is installed at one end of the tool body, and a tool holder interface is provided on the fixing cover. The mounting part is located between the tool body and the cutting part. The cutting part is cylindrical and has a rounded corner at the end away from the mounting part.

[0007] A chip removal mechanism is installed inside the tool body for collecting and discharging chips.

[0008] Optionally, locking nuts are provided on both sides of the fixed cover on the cutter body.

[0009] Optionally, the chip removal mechanism includes a centrifugal cavity disposed within the tool body, the inner wall of the centrifugal cavity being provided with a spiral chip removal groove, and a chip removal port being provided between the bottom wall of the centrifugal cavity and the cutting part.

[0010] Optionally, the inner wall of the centrifuge chamber is smoothed and coated with a titanium oxide coating.

[0011] Optionally, an opening is provided between the centrifuge chamber and the outer wall of the blade body, and a protective baffle is provided between the inner walls of the opening, with a plurality of through holes evenly provided on the protective baffle.

[0012] Optionally, a chip removal pipe is fixedly provided between the inner walls of the chip removal port.

[0013] Optionally, a sealing ring is provided on the inner wall of the tool holder interface.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention utilizes a centrifugal chamber, a spiral chip removal groove, a chip removal port, a through-hole, and a chip removal pipe. By employing the high-speed cutting rotation of the tool body, the chips generated during cutting are thrown into the inner wall of the centrifugal chamber under the action of centrifugal force and discharged to the outside of the tool body along the spiral chip removal groove. No additional power source is required, the structure is relatively simple and highly reliable. At the same time, the spiral chip removal groove can gradually decelerate the chips during the discharge process, avoiding the impact of high-speed chip flight on the processing environment and preventing chip accumulation and adhesion on the tool surface, thereby improving processing accuracy.

[0016] Furthermore, by setting up protective baffles and through holes, the filter barrier formed by the protective baffles and through holes can prevent foreign matter other than chips (such as impurities in the coolant, debris on the surface of the workpiece, etc.) from entering the centrifugal chamber during the cutting process, which would affect the chip removal effect or damage the tool, thus facilitating the normal operation of chip removal.

[0017] This invention enables the automatic collection and removal of chips generated during the cutting process, preventing chips from accumulating and adhering to the tool surface for a long time, thus affecting machining accuracy and surface roughness. This results in higher machining accuracy for the machining tool, and the invention requires no additional power source. Its relatively simple structure makes it suitable for widespread application.

[0029] Example

[0030] like Figure 1 and Figure 2 As shown, this utility model proposes an aluminum alloy machining tool, including a tool body 1. The tool body 1 includes an integrally formed mounting part 2 and a cutting part 3, and also includes a fixing cover 4 installed at one end of the tool body 1. The fixing cover 4 is provided with a tool holder interface 5. The mounting part 2 is located between the tool body 1 and the cutting part 3. The cutting part 3 is cylindrical, and the end away from the mounting part 2 is provided with a rounded corner. The tool body 1 is made of high-strength and high-toughness alloy steel material, such as high-speed steel or cemented carbide. This is because in the aluminum alloy machining process, the tool needs to withstand high cutting forces and temperatures. Alloy steel material can ensure that the tool body does not deform or get damaged during long-term use, ensuring the stability and durability of the tool. At the same time, considering the influence of centrifugal force on the tool body structure, the high strength characteristics of alloy steel material can effectively resist the stress generated by centrifugal force, ensuring the safe operation of the tool.

[0031] In addition, the tool body 1 is cylindrical in shape so that centrifugal force can be generated evenly during high-speed rotation. Locking nuts 6 or high-strength bolts are provided on both sides of the fixed cover 4 on the tool body 1 to ensure that the tool body 1 and the tool holder will not loosen during high-speed rotation, thereby ensuring the normal operation and machining accuracy of the tool body 1.

[0032] like Figures 2-4 As shown, the tool also includes a chip removal mechanism, which is set inside the tool body 1 for collecting and discharging chips. The chip removal mechanism includes a centrifugal chamber 7 located inside the tool body 1. The centrifugal chamber 7 is located inside the tool body 1, and its central axis coincides with the rotation axis of the tool body 1. This design ensures that when the tool rotates, the centrifugal force can be evenly applied to the chips in the centrifugal chamber, improving chip removal efficiency. The inner wall of the centrifugal chamber 7 is provided with a spiral chip removal groove 11, and a chip removal port 12 is provided between the bottom wall of the centrifugal chamber 7 and the cutting part 3. The inner wall of the centrifugal chamber 7 is smooth and is coated with a titanium oxide coating. The titanium oxide coating has a low coefficient of friction, which can not only reduce the friction between the chips and the inner wall, but also improve the wear resistance and corrosion resistance of the inner wall of the centrifugal chamber 7, extending the service life of the tool.

[0033] Furthermore, an opening 8 is provided between the outer wall of the centrifuge chamber 7 and the tool body 1, and a protective baffle 9 is provided between the inner walls of the opening 8. Several through holes 10 are evenly provided on the protective baffle 9. During the cutting process, the chips generated will enter the centrifuge chamber 7 through the opening 8 due to the centrifugal force generated by the rotation of the tool body 1. The diameter and number of through holes 10 can be designed according to the size and flow rate of the chips generated during processing, which can ensure that the chips can enter the centrifuge chamber smoothly and effectively block the entry of foreign matter.

[0034] Furthermore, a chip removal pipe 13 is fixedly provided between the inner walls of the chip removal port 12, and a sealing ring is provided on the inner wall of the tool holder interface 5. The sealing ring can ensure good sealing at the connection point and prevent coolant, chips and debris from entering the tool body, affecting the normal operation of the tool and the chip removal effect. The chips that enter the centrifugal chamber 7 will be discharged through the spiral chip removal groove 11 and the chip removal pipe 13 under the action of centrifugal force, and discharged from the bottom of the tool body 1.

[0035] In this embodiment, when the tool body 1 rotates at high speed to perform cutting operations, the chips generated by cutting will be thrown towards the inner wall of the centrifugal chamber 7 under the action of centrifugal force. That is, the chips enter from the through port 8, pass through the protection of the protective baffle 9 and the filter of the through hole 10 and enter the interior of the centrifugal chamber 7. The chips can also flow out of the tool body 1 along the spiral chip discharge groove 11, and finally be successfully discharged from the bottom of the tool body 1 through the chip discharge port 12 and the chip discharge pipe 13. No additional power source is required, the structure is relatively simple and highly reliable. At the same time, the spiral chip discharge groove 11 can gradually decelerate the chips during the discharge process, avoiding the impact of high-speed flying chips on the processing environment.

[0036] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
