[0001] This invention relates to the field of metal material processing technology, specifically to a high-performance metal material processing technology and equipment. Background Technology

[0002] In aerospace, high-end equipment manufacturing and other fields, complex structural components (such as blades and load-bearing parts) made of high-performance metal materials (such as titanium alloys and high-temperature alloys) have extremely high requirements for processing accuracy, mechanical properties and production efficiency. However, current metal material processing technology and supporting equipment still have many shortcomings, making it difficult to meet the stringent requirements of high-end manufacturing. These shortcomings are mainly reflected in the following aspects.

[0003] In the process of developing the invention, the inventors discovered that at least the following problems remain unresolved in the existing technology: During use, traditional high-performance metal material processing, under the influence of a single processing environment, struggles to precisely control the microstructure of the metal material; the superposition of multiple processing steps easily leads to material performance degradation; the processing accuracy of complex components is difficult to guarantee; and significant performance fluctuations exist during batch production. Therefore, a new technical solution needs to be designed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a high-performance metal material processing technology and equipment to solve the technical problems of current high-performance metal material processing, such as difficulty in accurately controlling the microstructure of metal materials under the action of a single processing field; the tendency of multiple processing steps to lead to material performance degradation; difficulty in ensuring the processing accuracy of complex components; and significant performance fluctuations during batch production.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-performance metal material processing technology and equipment, comprising the following processing steps: S1. First, select a metal ingot, cut and mill it into a cylindrical blank, use alcohol ultrasonic cleaning to remove surface oil, and then dry it in an oven; S2. Then fix the pre-treated billet onto the flexible fixture of the multi-field coupling processing equipment, calibrate the coaxiality between the billet center and the processing spindle through the laser positioning system, and attach strain gauges and set up infrared temperature measurement points on the surface of the billet to ensure that physical quantities can be collected in real time during the processing. S3. Restart the equipment control system, set the process parameters for the initial ultrasonic vibration field, pulse electromagnetic field and gradient temperature field, then start the hydraulic drive system to push the mold to apply pressure to the billet at a feed speed of 5 mm / min. At the same time, the ultrasonic transducer, electromagnetic coil and gradient heating furnace are activated simultaneously. When the strain gauge detects that the deformation of the billet reaches the design size of the metal material and the infrared thermometer shows that the overall temperature of the billet is stable, stop the hydraulic pressure to complete the plastic deformation and in-situ solid solution. S4. After the billet is formed, the billet is automatically transferred to the aging chamber with the fixture, the aging temperature control system is started, the cooling program is set, and when the temperature of the aging chamber drops to 150℃ and is held for 1 hour, the surface hardness of the billet is tested by an online hardness tester. S5. Restart the surface treatment module, set the ultrasonic impact parameters and electromagnetic induction parameters, and the ultrasonic impact head scans along the surface of the metal material at a speed of 2mm / s. The high-frequency impact causes a 12-15μm nanocrystalline layer to be formed on the surface of the metal material. At the same time, the electromagnetic induction heats the surface to 200℃, so as to form a dense protective film. Then, the surface roughness is detected by laser confocal microscope and salt spray test is performed. After the standard is met, the processing is completed.

The mounting end of the connecting plate is fixedly connected to the output end of a first electric push rod. The mounting end of the first electric push rod is fixedly connected to one end of a movable plate. The other end of the movable plate is slidably connected to the inner wall of a crossbeam and connected to a threaded rod through a threaded hole. Both ends of the threaded rod are rotatably connected to the inner wall of the crossbeam, with one end fixedly connected to the output end of a first servo motor.

[0012] In a preferred embodiment of the present invention, an oven mechanism is installed on one side of the ultrasonic cleaning mechanism. A second electric push rod is fixedly connected to the top of the oven mechanism. The output end of the second electric push rod is fixedly connected to the top of the sealing door. Two track plates are fixedly connected inside the oven mechanism. Push plates are connected to the inside of the two track plates respectively through a lead screw and a guide rod. One end of the lead screw is rotatably connected to the inner wall of one track plate, and the other end of the lead screw is fixedly connected to the output end of a second servo motor.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention employs a three-field time-series coupling logic of ultrasound, electromagnetic, and gradient temperature. In the forming stage, the cavitation effect generated by ultrasonic vibration and the Lorentz force generated by electromagnetic stirring are used to effectively break dendrite growth through high-frequency mechanical impact and dynamic melt disturbance, refining the metal grains to the submicron level. In the aging stage, a gradient temperature field combined with weak ultrasound is used to control the temperature gradient to achieve directional diffusion of solute atoms. Combined with the micro-amplitude vibration of ultrasound, it promotes the uniform precipitation of the second phase, significantly improving the overall performance of the material. In the surface treatment stage, ultrasonic impact and electromagnetic induction are used in synergy. The high-frequency stress wave generated by ultrasonic impact promotes the nano-sizing of the surface grains, while electromagnetic induction instantaneously heats and forms a dense oxide film, simultaneously achieving surface strengthening and protection.

[0016] This invention employs a four-step continuous process of pretreatment, forming, solution treatment, aging, and surface treatment, and combines the forming and solution treatment processes. It utilizes the work hardening heat generated during metal forming to simultaneously achieve solution treatment, eliminating the traditional 4-hour cooling process and 2-hour transfer time between processes. This effectively reduces heat loss and waiting time between processes, significantly improving production efficiency. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] Example 1: A high-performance metal material processing technology and equipment, comprising the following processing steps: S1. First, select a metal ingot, and then cut and mill it into a cylindrical blank. Use alcohol ultrasonic cleaning to remove surface oil stains, and then dry it in an oven. The size of the cylindrical blank is φ150mm×300mm. The cleaning time is 10-20min, the temperature of the drying oven is 120℃, and the drying time is 25-35min. After selecting metal ingots, they are sawed and milled into cylindrical blanks of a predetermined shape to ensure the initial dimensional accuracy of the blanks and lay the foundation for subsequent forming. Alcohol ultrasonic cleaning utilizes the cavitation effect of ultrasound to generate high-frequency vibrations in the alcohol medium, quickly removing impurities such as oil and cutting chips from the surface of the blank. Alcohol has both degreasing and volatile properties, which can prevent residual contaminants from affecting the plastic deformation and surface quality of the material during subsequent processing. The 120℃ oven drying treatment thoroughly removes residual alcohol and moisture from the surface of the blank, preventing moisture from vaporizing and generating bubbles during high-temperature processing, which could lead to defects such as pores and cracks inside the material, thus ensuring the density of the processed material. S2. Then fix the pre-treated billet onto the flexible fixture of the multi-field coupling processing equipment, calibrate the coaxiality between the billet center and the processing spindle through the laser positioning system, and attach strain gauges and arrange infrared temperature measurement points on the surface of the billet to ensure that physical quantities can be collected in real time during the processing. The coaxiality deviation between the billet center and the processing spindle is ≤0.01mm, the sampling frequency of the strain gauges on the surface of the billet is 100Hz, and the spacing of the infrared temperature measurement points is 5mm. The flexible fixture of the multi-field coupled machining equipment can adapt to the size of the blank, achieving stable clamping while avoiding damage to the blank surface. The laser positioning system, through high-precision laser ranging and calibration, ensures that the coaxiality deviation between the blank center and the machining spindle is minimized, avoiding material deformation and displacement due to uneven stress during the forming process, and ensuring the dimensional accuracy of complex structures such as metal materials. Strain gauges attached to the blank surface capture deformation data in real time with high-frequency sampling, and infrared thermography points are evenly distributed to comprehensively monitor the temperature distribution in all areas of the blank. The two work together to achieve dynamic feedback of physical quantities during the machining process, providing data support for subsequent process parameter adjustments and avoiding machining failures due to abnormal temperature or deformation. S3. Restart the equipment control system, set the initial ultrasonic vibration field, pulse electromagnetic field, and gradient temperature field process parameters, then start the hydraulic drive system to push the mold to press the billet at a feed speed of 5 mm / min. At the same time, activate the ultrasonic transducer, electromagnetic coil, and gradient heating furnace. When the strain gauge detects that the billet deformation reaches the design size of the metal material and the infrared thermometer shows that the overall temperature of the billet is stable, stop the hydraulic pressure to complete the plastic deformation and in-situ solution treatment. The process parameters of the ultrasonic vibration field are frequency 35 kHz, amplitude 8 μm, and power 5 kW. The process parameters of the pulse electromagnetic field are intensity 0.8 T, pulse frequency 80 Hz, and duty cycle 50%. The process parameters of the gradient temperature field are that the heating area is divided into 3 segments with temperatures set at 580℃, 560℃, and 540℃ respectively, and the temperature difference is controlled at ≤10℃. When the design size of the metal material is the maximum deformation of the blade body of 30 mm and the overall temperature of the billet is 560±5℃, the plastic deformation and in-situ solution treatment takes 2 hours. The ultrasonic vibration field, pulsed electromagnetic field, and gradient temperature field work together on the billet to form a multi-field coupled processing environment: the gradient temperature field creates a reasonable temperature gradient in the billet through segmented heating, reducing the material's yield strength and improving its plastic deformation capacity, while also providing the temperature conditions for solution treatment; the ultrasonic vibration field refines the material grains through high-frequency micro-amplitude vibration, reducing internal stress during the forming process and preventing cracks caused by stress concentration; the pulsed electromagnetic field improves the distribution of metal flow lines inside the material using electromagnetic force, promotes atomic diffusion, and improves the uniformity of material forming; the hydraulic drive system applies pressure at a constant feed rate, causing the billet to gradually undergo plastic deformation under the synergistic effect of multiple fields until it reaches the designed dimensions of the metal material; the simultaneous in-situ solution treatment dissolves the second-phase particles inside the material, eliminates work hardening, and prepares for subsequent aging strengthening, achieving integrated forming and solution treatment and shortening the processing cycle; S4. After the billet is formed, it is automatically transferred to the aging chamber with the fixture. The aging temperature control system is started, and the cooling program is set. The cooling program is as follows: the temperature drops from 560℃ to 150℃ at a rate of 8℃ / h, and the cooling rate is controlled in 5 segments: 560→450℃: 10℃ / h; 450→350℃: 8℃ / h; 350→250℃: 6℃ / h; 250→180℃: 8℃ / h; 180→150℃: 10℃ / h. After the temperature of the aging chamber drops to 150℃ and is held for 1 hour, the surface hardness of the billet is tested by an online hardness tester. After forming, the billet is transferred to an aging chamber and aged using a precisely programmed segmented cooling process. During aging, alloying elements gradually precipitate out, forming fine reinforcing phases that are uniformly dispersed in the matrix, significantly improving the material's hardness, strength, and wear resistance. Segmented cooling control prevents thermal stress from forming inside the material due to excessively rapid cooling, thus preventing cracking. Holding at 150℃ for 1 hour ensures sufficient precipitation and uniform distribution of the reinforcing phases, guaranteeing material performance stability. An online hardness tester monitors the surface hardness of the billet in real time, quickly determining whether the aging effect meets standards and preventing substandard products from entering subsequent processes. S5. Restart the surface treatment module, set the ultrasonic impact parameters and electromagnetic induction parameters. The ultrasonic impact parameters are frequency 40kHz, amplitude 5μm, and impact pressure 0.8MPa. The electromagnetic induction parameters are intensity 0.5T and frequency 100Hz. The ultrasonic impact head scans along the surface of the metal material at a speed of 2mm / s. The high-frequency impact causes a 12-15μm nanocrystalline layer to form on the surface of the metal material. At the same time, the electromagnetic induction heats the surface to 200℃ to form a dense protective film. The surface roughness is then detected by laser confocal microscopy and a salt spray test is performed. Once the standards are met, the processing is completed. Ultrasonic impact treatment involves applying high-frequency impact to the surface of a metal material, causing plastic deformation and refining the grains to the nanoscale, forming a 12-15μm nanocrystalline layer. This nanocrystalline layer possesses higher hardness, wear resistance, and corrosion resistance. Simultaneously, it eliminates residual tensile stress and introduces residual compressive stress, improving the material's fatigue resistance. Simultaneous electromagnetic induction heating raises the surface temperature to 200℃, forming a dense protective film that further enhances the material's corrosion resistance and prevents surface oxidation during use. Laser confocal microscopy is used to inspect surface roughness, verifying surface processing accuracy, while salt spray testing evaluates the material's corrosion resistance. This dual testing ensures product surface quality and reliability, ultimately completing the entire process for processing high-performance metal materials. After forming, the billet is automatically transferred to the aging chamber by the fixture. The aging temperature control system adopts a segmented cooling program (560→450℃: 10℃ / h; 450→350℃: 8℃ / h; 350→250℃: 6℃ / h; 250→180℃: 8℃ / h; 180→150℃: 10℃ / h), which is designed based on the thermophysical properties of the material. A faster cooling rate is used in the high-temperature range (560→450℃) and the low-temperature range (180→150℃) to avoid grain coarsening caused by prolonged high temperature. In the intermediate temperature range (350→250℃), a slower cooling rate is used to provide sufficient time for the precipitation of alloying elements, forming fine and uniform strengthening phases. Holding at 150℃ for 1 hour ensures that the reinforcing phase is fully released and dispersed in the matrix, significantly improving the material's hardness and wear resistance. An online hardness tester monitors the surface hardness of the billet in real time, quickly assessing the aging effect. Defective products are promptly reworked to prevent them from flowing into subsequent processes, ensuring consistent performance of the finished product.

[0021] For details, see Figures 1 to 4 A high-performance metal material processing equipment includes an ultrasonic cleaning mechanism 1. The ultrasonic cleaning mechanism 1 is internally connected to a carrier plate 11. Electromagnets 12 are attracted to both sides of the carrier plate 11. The other end of the electromagnet 12 is fixedly connected to both ends of a connecting plate 13. The mounting end of the connecting plate 13 is fixedly connected to the output end of a first electric push rod 14. The mounting end of the first electric push rod 14 is fixedly connected to one end of a moving plate 15. The other end of the moving plate 15 is slidably connected to the inner wall of a crossbeam 16 and connected to a threaded rod 17 through a threaded hole. The two ends of the threaded rod 17 are rotatably connected to the inner wall of the crossbeam 16, one end of which is fixedly connected to the output end of a first servo motor 18. Metal ingots are selected and sawn and milled into cylindrical blanks with a diameter of φ150mm × 300mm. This size design is based on the volume allowance requirements for subsequent metal material forming, ensuring that the blank has sufficient deformation space. The ultrasonic cleaning mechanism 1 achieves automated cleaning through a linkage structure of carrier plate 11, electromagnet 12, electric push rod, and servo drive: the carrier plate 11 carries the blank, and the electromagnets 12 on both sides are energized to generate magnetic attraction to the blank, preventing the blank from shifting during cleaning; the first electric push rod 14 extends and retracts, driving the carrier plate 11 to rise and fall, so that the blank is completely immersed in the alcohol cleaning solution; the ultrasonic waves generate a high-frequency cavitation effect in the alcohol medium, impacting the surface of the blank to peel off oil and cutting debris. The cleaning time of 10-20 minutes can be flexibly adjusted according to the degree of oil contamination, and the degreasing and volatility of alcohol can avoid residual pollution. After cleaning, the first servo motor 18 drives the threaded rod 17 to rotate, and through the threaded transmission, the moving plate 15 slides along the crossbeam 16 to transfer the carrier plate 11 and the blank to the drying oven mechanism 19. The whole process is automated to reduce manual intervention and ensure cleaning efficiency and consistency.

[0022] Further, see Figures 1 to 4An oven mechanism 19 is installed on one side of the ultrasonic cleaning mechanism 1. A second electric push rod 2 is fixedly connected to the top of the oven mechanism 19. The output end of the second electric push rod 2 is fixedly connected to the top of the sealing door. Two track plates 21 are fixedly connected inside the oven mechanism 19. Push plates 24 are connected to the inside of the two track plates 21 respectively through lead screws 22 and guide rods 23. One end of the lead screw 22 is rotatably connected to the inner wall of one track plate 21, and the other end of the lead screw 22 is fixedly connected to the output end of the second servo motor 25. Both ends of the guide rod 23 are fixedly connected to the other track plate 24. Inside the track plate 21, a processing mechanism 26 is fixedly connected to the other side of the oven mechanism 19. A third electric push rod 27 is fixedly connected to the top of the processing mechanism 26. The output end of the third electric push rod 27 is fixedly connected to the top of the sealing door. A hydraulic rod 28 is installed on one side of the third electric push rod 27. The output end of the hydraulic rod 28 is fixedly connected to the pressure applying mechanism 29. A fourth electric push rod 3 is fixedly connected to each of the four corners of the processing mechanism 26. The output end of the fourth electric push rod 3 extends into the interior of the processing mechanism 26 and is fixedly connected to one end of the positioning head 31. The drying oven mechanism 19 achieves the connection between drying and transfer through a sealed door, track plate 21, push plate 24, and servo drive: the second electric push rod 2 controls the lifting and lowering of the sealed door, forming a closed space when closed. The oven temperature of 120℃ can quickly evaporate the alcohol and moisture on the surface of the blank. The drying time of 25-35 minutes ensures that the moisture is completely removed, avoiding the formation of pores inside the material due to water vaporization during high-temperature processing. The two track plates 21 inside the oven are connected to the push plate 24 through the lead screw 22 (power end) and the guide rod 23 (guide end), respectively. The second servo motor 25 drives the lead screw 22 to rotate, which drives the push plate 24 to move smoothly along the guide rod 23, pushing the blank transferred from the ultrasonic cleaning mechanism 1 to the central area of ​​the oven (where it is heated evenly). After drying, it is pushed in the opposite direction to the outlet, providing precise feeding for subsequent processing steps and achieving a seamless connection between cleaning and drying.

[0023] It is worth noting that, see Figures 1 to 4 One side of the processing mechanism 26 is connected to one side of the oven mechanism 19. The position of the first electric push rod 14 corresponds to the center position of the two track plates 21. The size of the carrier plate 11 matches the size of the groove inside the processing mechanism 26. The flexible fixture of the multi-field coupled machining equipment can adaptively clamp the blank according to its size, avoiding damage to the blank surface caused by rigid clamping. The laser positioning system calibrates the coaxiality between the blank center and the machining spindle through high-precision laser ranging. The stringent requirement of a deviation of ≤0.01mm is crucial to ensuring the forming accuracy of complex curved surfaces of metal materials. If there is eccentricity, it will lead to uneven blade thickness and forming deviation. Strain gauges (100Hz sampling frequency) attached to the blank surface can capture instantaneous deformation in real time, and infrared thermometers arranged at 5mm intervals can comprehensively monitor the temperature distribution in various areas of the blank. The data from both are transmitted synchronously to the control system, providing dynamic feedback for subsequent multi-field parameter adjustments and avoiding machining failure due to abnormal temperature or deformation. The machining mechanism 26 is equipped with a fourth electric push rod 3 and a positioning head 31 at the four corners. The four sets of electric push rods extend and retract synchronously, driving the positioning head 31 to move closer to the center of the blank. The blank position is further calibrated through mechanical positioning, forming a double precision positioning with laser positioning. This ensures that the blank remains coaxial with the mold and spindle during the forming process, laying the positional foundation for subsequent multi-field coupled processing. The hydraulic rod 28 of the processing mechanism 26 pushes the pressure application mechanism 29 at a constant feed speed of 5 mm / min, which drives the mold to apply continuous pressure to the billet. Under the synergistic effect of multiple fields, the billet gradually undergoes plastic deformation. When the strain gauge detects that the maximum deformation of the blade reaches 30 mm (the design size of the metal material) and the infrared thermometer shows that the overall temperature of the billet is stable, the control system automatically stops the hydraulic pressure application. The whole process takes 2 hours, realizing the integration of plastic deformation and in-situ solution treatment without the need for separate solution treatment, shortening the processing cycle, and avoiding material property fluctuations caused by secondary heating. The third electric push rod 27 at the top of the processing mechanism 26 controls the sealing door to close, ensuring the stability of the multi-field environment and reducing external interference.
