It has the excellent mechanical, physical and chemical properties of metal and glass, and has good mechanical properties such as high strength, high hardness, high elastic limit and wear resistance.

[0003] Threaded holes are structures that connect and support bulk amorphous alloy parts. Milling is the common processing method for threaded hole forming in the industry. The unique atomic arrangement of bulk amorphous alloys makes them extremely temperature sensitive. In the existing bulk amorphous alloy machining process, when the machining temperature exceeds its crystallization temperature Tx, the alloy's processed surface material crystallizes and loses its original mechanical and chemical properties; when the machining temperature is lower than its glass transition temperature Tg, the high strength, high hardness, and high fracture toughness of amorphous alloys will cause serious tool wear.

[0064] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0065] Amorphous alloy is a new type of high-performance metal material formed under high-speed cooling. It has the excellent mechanical, physical and chemical properties of metal and glass, and has good mechanical properties such as high strength, high hardness, high elastic limit and wear resistance.

[0066] Threaded holes are structures that connect and support bulk amorphous alloy parts. Milling is the common processing method for threaded hole forming in the industry. The unique atomic arrangement of bulk amorphous alloys makes them extremely temperature sensitive. In the existing bulk amorphous alloy machining process, when the machining temperature exceeds its crystallization temperature Tx, the alloy's processed surface material crystallizes and loses its original mechanical and chemical properties; when the machining temperature is lower than its glass transition temperature Tg, the high strength, high hardness, and high fracture toughness of amorphous alloys will cause serious tool wear.

[0067] Therefore, the threaded hole milling processing of bulk amorphous alloys has problems of low processing efficiency and poor tool cutting performance, which limits the high-quality development of threaded hole structure manufacturing of bulk amorphous alloy components.

[0068] Based on this, the present application provides a thread milling cutter tooth, a multi-cutting edge tool, and a threaded hole cutting method and equipment.

[0069] Example 1

[0070] See also Figure 2 to Figure 5The present embodiment provides a thread milling cutter tooth, which is arranged on a blade portion 1. The blade portion 1 is the working part when cutting amorphous alloys, and includes a first-level thread bottom cutting edge 5 and a thread side cutting edge 6. The first-level thread bottom cutting edge 5 effectively cuts into the material during cutting to form a thread bottom shape, and the thread side cutting edge 6 is used to cut amorphous alloys to form a thread side shape.

[0071] The first-level thread root cutting edge 5 is arranged at the tip portion 7 of the outermost circle away from the central axis. The tip portion 7 is the sharp part that directly acts on the amorphous alloy during cutting. The tip portion 7 is opened with P tool grooves 8 by laser cutting. The P tool grooves 8 form P thread root cutting edges. The first-level thread root cutting edge 5 also belongs to the thread root cutting edge. The thread root cutting edge is the main cutting edge of the tool. The thread root cutting edges are all used for cutting to form the thread hole root shape. The tool groove 8 is also used for chip removal.

[0072] Specifically, P thread bottom cutting edges are arranged adjacent to the first-level thread bottom cutting edge 5, P is an integer greater than or equal to 1, and among the P thread bottom cutting edges, the second-level thread bottom cutting edge 9 is adjacent to the first-level thread bottom cutting edge 5, and the P+1-level thread bottom cutting edge is farthest from the first-level thread bottom cutting edge 5. During the threaded hole processing, the first-level thread bottom cutting edge 5 serves as the main cutting edge for cutting first, and the second-level thread bottom cutting edge 9 performs a secondary cutting on its processing surface after the first-level thread bottom cutting edge 5 completes cutting, and the third-level thread bottom cutting edge performs a third cutting on its processing surface after the second-level thread bottom cutting edge 9 completes cutting, and so on, until the last-level thread bottom cutting edge is cut.

[0073] The blade distance between two adjacent thread bottom cutting edges ranges from 5um to 40um, that is, the blade distance between the first-level thread bottom cutting edge 5 and the second-level thread bottom cutting edge 9, and the blade distance between the P-level thread bottom cutting edge and the P+1-level thread bottom cutting edge all belong to the above numerical range; the blade distance numerical range is obtained by finite element analysis, cutting heat transient conduction simulation and the width of the bonding layer of the processing material of the tip part 7 in actual experiments. Its purpose is to ensure that the cutting edge of the next-level thread bottom can utilize the cutting heat generated by the cutting edge of the previous-level thread bottom, to achieve cutting of amorphous alloys at the glass transition temperature Tg, reduce the cutting force of the cutting edge, improve the cutting performance of the cutting edge, and prevent the processed surface from causing serious wear to the cutting edge.

[0074] The angle range of the first-stage thread bottom cutting edge 5 is 5° to 15°, the angle range of the second-stage thread bottom cutting edge 9 is 10° to 20°, and the helix angle range of the thread is 10° to 50°, that is, the angle of the tooth 3 deviating from the center axis. The angle range can be adjusted according to actual production.

[0075] In practical applications, there is no limit to the number of thread bottom cutting edges, and the specific number is based on the requirement that processing can be completed with one feed.

[0076] The working principle of a thread milling cutter tooth provided by the present invention is:

[0077] Starting from the first-level thread bottom cutting edge 5, the amorphous alloy is cut step by step. Each level of thread bottom cutting edge is further processed after the previous level of thread bottom cutting edge is completed, until the last level of thread bottom cutting edge completes cutting. The blade distance is accurately controlled within the range of 5um to 40um to ensure that the next level of thread bottom cutting edge can utilize the cutting heat generated by the previous level of thread bottom cutting edge to cut above the glass transition temperature Tg of the amorphous alloy.

[0078] A thread milling cutter provided in the present application processes threaded holes by designing a multi-level thread bottom cutting edge, reducing the cutting pressure of the cutting edge, improving the cutting efficiency, and controlling the edge distance to ensure that the cutting edge at the bottom of each level of thread teeth can effectively utilize the cutting heat generated by the previous level, and cut above the glass transition temperature Tg of the amorphous alloy, thereby improving the cutting performance of the cutter tooth 3, reducing wear, and extending the life of the cutter tooth 3; and further improving the cutting efficiency and the surface quality of the threaded hole processing by optimizing the cutting edge structure and angle.

[0079] Example 2

[0080] See also Figure 1 to Figure 5 A multi-cutting edge tool provided in this embodiment includes a blade portion 1 and a shank portion 2, wherein the blade portion 1 is a working portion when cutting amorphous alloys, and the shank portion 2 is connected to a cutting device, and the blade portion 1 is provided with teeth 3 and chip grooves 4, wherein the teeth 3 are used for cutting materials, and the chip grooves 4 discharge the chips generated by cutting in time during the cutting process, and a first-level thread bottom cutting edge 5 is formed between the teeth 3 and the chip grooves 4, and the first-level thread bottom cutting edge 5 effectively cuts into the material during cutting to form a thread bottom shape.

[0081] The cutter teeth 3 are provided with M layers, and the design of the multi-layer cutter teeth 3 can improve the cutting efficiency. The chip grooves 4 are provided with N strips from top to bottom on the cutting edge portion 1, and the plurality of chip grooves 4 can efficiently remove chips and prevent chip blockage. The N chip grooves 4 are evenly distributed circumferentially on the circumference of the cutter teeth 3 to improve the machining accuracy. The angles between each chip groove 4 and the cutter teeth 3 are equal to ensure that the cutting force is evenly distributed. The N chip grooves 4 and the M layers of cutter teeth 3 form N*M first-stage thread bottom cutting edges 5; wherein M and N are both integers greater than or equal to 2.

[0082] The cutting efficiency is improved by arranging multiple layers of cutter teeth 3 and multiple chip grooves 4. Multiple thread bottom cutting edges are formed between the cutter teeth 3 and the chip grooves 4, thereby improving the cutting efficiency of the tool. Moreover, due to the numerical setting of the blade distance, the tool can cut the amorphous alloy at the glass transition temperature Tg, thereby reducing the wear of the amorphous alloy on the tool and extending the tool life.

[0083] A thread side cutting edge 6 is also formed between the chip groove 4 and the cutter teeth 3. The thread side cutting edge 6 is used to cut the amorphous alloy to form the thread side shape. A single chip groove 4 and a single layer of the cutter teeth 3 form two thread side cutting edges 6. The first-level thread bottom cutting edge 5 is between the two thread side cutting edges 6.

[0084] The multi-cutting edge tool is a thread milling cutter, which is a cutting tool that uses milling to process threads. It can be made of cemented carbide material, and the coating material is determined according to specific cutting parameters and cutting environment. The blade part 1 and the handle part 2 are connected by a connecting part 10, and the connecting part 10 realizes the connection function. The blade part 1 is installed on one end of the connecting part 10 through a tool avoidance rod 11. The main function of the tool avoidance rod 11 is to reduce the vibration and heat accumulation of the tool during the processing, thereby improving the processing accuracy and tool life.

[0085] The working process of a multi-cutting edge tool provided by the present invention is as follows:

[0086] The blade portion 1 contacts the amorphous alloy material. As the tool rotates, the teeth 3 cut layer by layer along the surface of the material to form a thread shape. At the same time, the chip groove 4 discharges the debris generated in the cutting process in time to prevent blockage. The multi-level cutting edges cut in sequence along the feed direction to ensure continuous and uniform cutting effects. The design of multi-layer teeth 3 and circumferentially equidistantly distributed chip grooves 4 makes the cutting force evenly distributed, thereby improving machining accuracy and efficiency.

[0087] A multi-cutting edge tool provided in the present application realizes fine processing of amorphous alloy threaded holes by step-by-step processing of multi-level thread bottom cutting edges, and due to the numerical setting of the blade distance, the tool can cut the amorphous alloy at the glass transition temperature Tg, thereby reducing the wear of the amorphous alloy on the tool and extending the tool life; the design of multi-layer teeth 3 and multiple chip grooves 4 improves the cutting efficiency and chip removal capacity, and is suitable for high-precision and high-efficiency thread processing needs.

[0088] Example 3

[0089] See also Figure 1 to Figure 5 This embodiment provides a threaded hole cutting method using the multi-cutting edge tool of embodiment 1, comprising the following steps:

[0090] S1, using the above-mentioned multi-cutting edge tool to perform spiral milling of threaded holes on the amorphous alloy, after the first-stage thread bottom cutting edge 5 cuts the amorphous alloy, a machined surface is formed on the amorphous alloy, and the heat brought by the cutting action makes the machined surface temperature above the glass transition temperature Tg of the amorphous alloy;

[0091] S2, the second-stage thread bottom cutting edge 9 performs a second cutting on the machined surface which is above the glass transition temperature Tg, and transfers the generated cutting heat to the third-stage thread bottom cutting edge through the temperature conduction effect, so that the secondary machined surface temperature is kept above the glass transition temperature Tg, waiting for further processing;

[0092] S3, according to the number of thread bottom cutting edges of the multi-cutting edge tool, feed and cut in sequence, during the cutting process, the friction force generated by the previous thread bottom cutting edge causes the surface of the workpiece to be locally heated up, so that the machined surface reaches above the glass transition temperature Tg, and when the next thread bottom cutting edge is cutting, the surface to be machined is always above the glass transition temperature Tg;

[0093] S4. The surface of the amorphous alloy processed at the next level is cooled and lubricated by spraying coolant, so that the temperature of the surface being continuously cut is controlled below the crystallization temperature Tx of the amorphous alloy.

[0094] The multi-level thread bottom cutting edges cut in sequence, and the blade distance is set so that each level of cutting edge can utilize the cutting heat generated by the previous level of cutting edge to control the processed surface temperature of the amorphous alloy above the glass transition temperature Tg. At the same time, cooling technology is used to control the processing temperature below the crystallization temperature Tx of the amorphous alloy. The good plasticity of the amorphous alloy in this temperature range is utilized to avoid processing defects caused by crystallization of the processed surface of the amorphous alloy, reduce the cutting force of the cutting edge, improve the cutting edge performance, and reduce tool wear.

[0095] In the above-mentioned S1 to S3, the range of the cutting speed vc is 10 to 100 m / min, the range of the feed rate per revolution fr is 0.01 to 0.05 mm / r, and the range of the radial cutting depth ae is 0.01 to 0.05 mm.

[0096] Controlling parameters such as cutting speed vc, feed per revolution fr and radial depth of cut ae helps optimize the cutting process, ensure the surface quality of threaded hole processing and reduce the risk of tool breakage.

[0097] The coolant in S4 includes at least one of trace oil, trace water, low-temperature cold air, supercritical carbon dioxide and low-temperature liquid nitrogen; the cooling method in S4 includes at least one of spray cooling, internal cooling, external cooling, liquid aerosol spray, and liquid compressed air cooling.

[0098] Select coolant and cooling method according to specific processing requirements and environmental conditions to achieve the best cooling effect and processing efficiency. Cooling technology can quickly take away the heat in the cutting area, reduce the heat-affected area, and lubricate the processing surface, thereby improving processing accuracy and processing surface quality, and avoiding deformation or crystallization of materials due to high temperature.

[0099] In this embodiment, a comparative test of milling a M1.4 threaded hole is performed using an existing thread milling cutter and a double-cutting-edge thread milling cutter according to the present invention:

[0100] The cutting material used is industrial-grade zirconium-based amorphous alloy material Vit105, with a size of 120mm×10mm×2mm, and the glass transition temperature Tg of the amorphous alloy material is 360°C; the experimental cutting tools select conventional single-cutting edge thread milling cutter and the improved double-cutting edge thread milling cutter of the present invention, wherein the angle of the first-stage thread tooth bottom cutting edge 5 of the double-cutting edge thread milling cutter is 5°, the angle of the second-stage thread tooth bottom cutting edge 9 is 10°, the helix angle of the thread is 45°, the distance between the two-stage thread tooth bottom cutting edges is 5μm, the cutting speed of the double-cutting edge thread milling cutter vc=30, 40, 50m / min, the feed rate per revolution fr=0.0157, 0.0250, 0.0333m / min, and the radial cutting width ae=0.03mm; the processing is carried out in the cutting fluid environment of the machining center, and the maximum speed is 15000r / min; the comparison results are as follows:

[0101] (1) Under the same cutting parameters and cooling and lubrication conditions, the double-cutting-edge thread milling cutter of the present invention reduces the cutting force by 13% to 18% compared with the conventional single-cutting-edge thread milling cutter; the reduction in cutting force can improve cutting performance and reduce tool wear;

[0102] (2) Under the premise of ensuring that the threaded hole size is qualified, using the same cutting parameters and cooling and lubrication conditions, the double-cutting-edge thread milling cutter of the present invention has a tool life increased by 80% to 100% compared with a conventional single-cutting-edge thread milling cutter; the increased tool life can save production costs;

[0103] (3) Under the premise of ensuring that the threaded hole size is qualified, cooling and lubrication technology is adopted. Compared with conventional single-cutting-edge thread milling cutters, the double-cutting-edge thread milling cutter of the present invention can select more efficient cutting processing parameters, and the processing efficiency can be improved by 20% to 50%. The improvement in processing efficiency improves the production capacity and resource utilization of amorphous alloy threaded hole processing.

[0104] It can be seen from the above description and experimental data that a threaded hole cutting method provided by the present invention controls the cutting temperature by adjusting the cutting speed, feed speed, cutting depth, tool angle and cutting environment; in the amorphous alloy cutting process, the amorphous alloy is threadedly cut in sequence by using a multi-level thread bottom cutting edge, and each level of cutting edge can utilize the cutting heat generated by the previous level of cutting edge to control the processed surface temperature of the amorphous alloy above the glass transition temperature Tg, and at the same time, the cooling technology is used to control the processing temperature below the crystallization temperature Tx of the amorphous alloy, which not only avoids the wear of the tool caused by the increased hardness of the amorphous alloy due to the processing surface temperature being lower than the glass transition temperature Tg, but also avoids the crystallization and loss of the original mechanical and chemical properties due to the temperature being higher than the crystallization temperature Tx. Therefore, this method can not only improve the cutting performance, but also avoid material deformation, and realize efficient and high-quality threaded hole processing of amorphous alloys.
