Description

Technical Field

[0001] The utility model belongs to the technical field of cutting tools, and particularly relates to a subsonic resonance cutting tool for processing ceramics and carbon fibers. Background Art

[0002] Cutting tools are tools used for cutting in mechanical manufacturing. Cutting tools can be divided into five categories according to the form of the workpiece processing surface:

[0003] Tools for processing various external surfaces, including turning tools, planing tools, milling cutters, external surface broaches and files, etc.;

[0004] Hole processing tools, including drills, reamer drills, boring tools, reamers and internal surface broaches;

[0005] Thread processing tools, including taps, dies, automatic opening and closing thread cutting heads, thread turning tools and thread milling cutters;

[0006] Gear processing tools, including hobs, gear shaping cutters, gear shaving cutters, bevel gear processing tools, etc.;

[0007] Cutting tools, including toothed circular saw blades, band saws, bow saws, cut-off turning tools and saw blade milling cutters, etc.

[0008] In order to achieve cutting, the tool must have a certain cutting depth relative to the workpiece and move relative to the surface of the workpiece to be processed. This relative movement is sometimes linear and sometimes rotational, and is usually achieved by a machine tool.

[0009] For example, patent application 201922157875.3 discloses a tool head structure and a cutting tool, the tool head structure includes a cutting edge portion, the cutting edge portion includes a cutting body, the outer surface of the cutting body is an arc surface convex forward, the outer surface of the cutting body is provided with a first cutting edge and at least two second cutting edges, the first cutting edge extends from one side of the cutting body to its top area, and then extends to the other side of the cutting body, each second cutting edge is respectively arranged on both sides of the first cutting edge; the first cutting edge includes a first section, a middle section and a second section connected in sequence, and the blade widths of the second cutting edge, the first section and the second section are all greater than the blade width of the middle section.

[0010] However, some materials cannot be cut by ordinary cutting tools, such as ceramics and carbon fiber products. Ceramics are typical hard and brittle materials with high hardness and wear resistance; carbon fiber is mainly composed of carbon elements, and has the characteristics of high temperature resistance, friction resistance, thermal conductivity and corrosion resistance, and has high strength and modulus; in order to achieve the cutting of products with a certain hardness such as ceramics and carbon fibers, specific cutting tools are required. In addition to easy-to-cut ceramics, such as general engineering ceramics and carbon fibers, only superhard tool materials can do the job, which is usually achieved through diamond cutting tools. For example, patent application 202022682803.3 discloses a high-toughness diamond polycrystalline cutting tool, which relates to the field of hardware tool technology, including a blade, a cutter head and a fixed rotating rod. The blade is fixed on the outside of the cutter head, and bolts are installed on the outside of the blade. The bolts pass through the blade and the cutter head. A fixed rod is fixed under the cutter head, and a mounting rod is fixed to the end of the fixing rod away from the cutter head. A slide cylinder is installed on the outside of the end of the fixing rod away from the fixed rod, and a fixed rotating rod is installed on the outside of the slide cylinder. The utility model has high hardness, wear resistance and impact toughness by fixing a diamond polycrystalline blade on the outside of the blade.

[0011] However, diamond cutting tools are expensive, and in order to ensure product quality, they need to be finely ground and cut slowly, and the cutting efficiency is not high. Utility Model Content

[0012] Based on this, the primary purpose of the utility model is to provide a subsonic resonance cutting tool, which is used for high-speed processing to achieve cutting of ceramic and carbon fiber products, and is used for ceramic and carbon fiber processing.

[0013] Another object of the utility model is to provide a subsonic resonant cutting tool, which generates wind energy by clockwise high-speed rotation. The wind energy enters counterclockwise through the inclined hole on the kinetic energy generating bin, blowing the impeller to rotate at high speed. At the same time, the central axis of the impeller is eccentric and unbalanced, which will generate resonant sound waves. The resonant sound waves are transmitted from the clamping cavity to the jacket to the tool, which will make the processed products more efficient and faster.

The central axis of the impeller is eccentric and unbalanced, which will generate resonant sound waves. The resonant sound waves are transmitted from the jacket to the tool, which will make the product more efficiently and quickly processed.

[0023] Furthermore, six circular holes are evenly distributed on the outer wall of the kinetic energy generating chamber A, and the six circular holes are air inlet holes. Each circular hole has an inclined angle of 30 degrees to facilitate smooth air intake during rotation.

[0025] Furthermore, the bearing is a high-precision small bearing.

[0026] Furthermore, the impeller has an angle of 30 degrees for each blade and an R-shaped notch on the central axis of the impeller. The notch will produce an imbalance when rotating at high speed, so that a resonant sound wave will be generated when the tool speed reaches 48,000 rpm.

[0027] Furthermore, the middle of the jacket is a hollow structure for clamping the cutting tool.

[0028] Furthermore, the air inlet hole is an inclined hole.

[0029] Compared with the prior art, the beneficial effects of the utility model are as follows:

The central axis of the impeller is eccentric and unbalanced, and resonant sound waves are generated when the tool speed reaches 48,000 rpm. The resonant sound waves are transmitted from the jacket to the tool, which can process and shape products more efficiently and quickly.

[0039] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0040] Figure 1-3The figure shows a subsonic resonant cutting tool realized by the utility model, which includes a kinetic energy generating chamber, a bearing 3, an impeller 4, a jacket 5 and a nut 6, wherein the kinetic energy generating chamber has a kinetic energy generating chamber A part 1 and a kinetic energy generating chamber B part 2.

[0041] Among them, the front end of the kinetic energy generating chamber A part 1 has an external thread, which is connected to the kinetic energy generating chamber B part 2 through the external thread, and there is a concave cavity at the front end of the kinetic energy generating chamber A part, and the concave cavity is the air intake chamber 7, and the air intake chamber 7 is equipped with an impeller 4.

[0042] At the same time, the outer wall of the kinetic energy generating chamber A portion 1 is provided with a plurality of air inlet holes 12, the air inlet holes 12 are connected to the air inlet chamber 7, and the air inlet holes 12 blow the impeller 4; the air inlet holes 12 are six circular holes, wherein, in combination with Figure 3 As shown, each circular hole has an oblique angle of 30 degrees, and a suitable angle of the air inlet hole 12 facilitates smooth air intake during rotation, thereby enabling the blowing impeller to rotate at high speed.

[0043] The kinetic energy generating chamber A also has a clamping portion 11 with a reduced diameter, which facilitates clamping.

[0044] The kinetic energy generating chamber B part 2 has an internal thread, which is connected to the kinetic energy generating chamber A part 1 through the internal thread. At the same time, the kinetic energy generating chamber B part also has an external thread, which is connected to a nut 6;

[0045] The bearing 3 is a high-precision small bearing, which is respectively arranged at the kinetic energy generating chamber A part 1 and the kinetic energy generating chamber B part 2, and is used to set the impeller 4. The impeller 4 is supported by the high-precision small bearing so as to be able to rotate at high speed.

[0046] The impeller 4 has six blades 41, an R-shaped impeller notch 42 on the central axis of the impeller, and, as Figure 4-6 As shown, the impeller notch 42 is distributed longitudinally along the blade 41, so that the impeller notch 42 makes the central axis of the impeller present an eccentric unbalanced structure, which will produce an imbalance when rotating at a high speed, thereby generating a resonant sound wave when the tool speed reaches 48000 rpm. The resonant sound wave is transmitted from the jacket to the tool, which will make the product more efficiently and quickly processed.

[0047] In other embodiments, there may be more than one R-shaped impeller notch 42 as long as the central axis of the impeller can be made to present an eccentric and unbalanced structure.

[0050] The jacket 5 and the nut 6 are both prior art and will not be described in detail here.

[0051] To sum up, the utility model generates a lot of wind energy by the clockwise high-speed rotation of the impeller. The wind energy enters the air inlet bin counterclockwise through the inclined hole on the kinetic energy generating bin. Due to the wind resistance, the wind energy enters the air inlet bin smoothly to blow the impeller to rotate at a high speed. The central axis of the impeller is eccentric and unbalanced. When the tool speed reaches 48,000 rpm, a resonant sound wave is generated. The resonant sound wave is transmitted from the clamping cavity to the jacket to the tool, which will make the product more efficiently and quickly processed.

[0052] In short, the cutting tool realized by the utility model is used for high-speed processing, and the speed can reach 80,000 or 100,000 revolutions per minute. When the tool speed is higher than 80,000 revolutions, the ratio of the tool speed and the tool circumference is close to the speed of sound, which is equal to 360 meters per second. It is suitable for processing difficult-to-process products such as ceramics and carbon fibers.
