Description

Technical Field

[0001] The present invention relates to the technical field of composite material preparation, and particularly to an intelligent production line and production method for magnetic field-assisted alloy centrifugal casting. Background Art

[0002] In recent years, with the surge in demand for high-performance alloy materials in the high-end manufacturing field, carbon group nanomaterials (such as graphene and carbon nanotubes) have become a research hotspot for enhancing and modifying metal matrix composites due to their excellent mechanical, electrical, and thermal properties. Research shows that introducing carbon group nano-reinforcing phases into alloy matrices can significantly improve material hardness, wear resistance, and corrosion resistance; however, traditional preparation processes have significant technical bottlenecks: mechanical stirring is prone to causing nanoparticle agglomeration, ultrasonic dispersion has energy attenuation problems, chemical modification faces challenges in controlling interfacial reactions, electrochemical deposition is only applicable to specific alloy systems, and the liquid phase method has a risk of solvent residue. The above processes generally have defects such as uneven dispersion of magnetic nanoparticles and low interfacial bonding strength, and mostly remain in the laboratory small-batch preparation stage, making it difficult to achieve large-scale industrial production. The complex preparation processes and high costs also limit their promotion in practical applications.

[0003] A prior art discloses a method and device for preparing a graphene magnesium-based alloy with ultra-high thermal conductivity (patent number 201811633803.5), including orienting graphene in a magnesium alloy melt by magnetic field assistance and achieving unidirectional solidification by combining with a gas-cooled disk. Although the magnetic field effect can improve the orientation of graphene and the thermal conductivity of the material, this invention not only has high sensitivity to process parameters and a sharp increase in equipment costs due to the need to precisely control the magnetic field intensity and melt temperature, making large-scale production difficult, but also has a fixed magnetic field direction (such as vertical or horizontal), resulting in graphene being arranged only in a single direction and having certain limitations in the degree of uniform distribution.

[0004] Another prior art discloses a method for preparing a graphene-reinforced aluminum alloy tensile and thermal conductivity composite material (patent number 202010574934.1), including dispersing graphene and aluminum alloy powder by ball milling and forming an oriented structure by combining cold pressing and vacuum hot pressing. Although the hot pressing process can reduce the generation of brittle Al4C3 phases and improve the tensile strength, this solution not only has low production efficiency and high energy consumption due to the long ball milling time and the hot pressing temperature being close to the melting point of aluminum, but also graphene is still prone to agglomeration at high contents, resulting in uneven local thermal conductivity of the composite material and significant fluctuations in interfacial bonding strength.

[0005] Another prior art discloses a method for preparing graphene-reinforced aluminum matrix composites by friction stir processing (invention number CN106916990B). This method uses an aluminum alloy as the base material, deposits graphene on the surface of SiC particles by electroless copper plating, fills it in a preset groove, and then realizes the preparation of the composite material through the friction stir process. This solution improves the problem of graphene distribution uniformity by combining physical mixing and mechanical stirring. However, there are problems such as excessive sensitivity of process parameters (such as rotation speed, tilt angle), which need to be precisely controlled. Locally, graphene agglomeration may still occur due to uneven stirring. In addition, relying on copper plating to promote bonding may introduce additional complexity, and the equipment needs to be modified based on a milling machine, resulting in limited adaptability for large-scale production, and its long-term stability still needs to be verified.

[0006] In summary, in the prior art, the distribution uniformity of nano-reinforcing phases in composites needs to be improved. In traditional processes, magnetic nanoparticles are prone to agglomeration due to van der Waals forces and are difficult to achieve uniform dispersion in alloy solutions; the preparation process is complex and costly, and many processes remain in the laboratory stage and are difficult to mass-produce industrially; the process parameters of existing methods are highly sensitive, such as strict requirements for melt temperature, ball milling duration, hot pressing conditions, friction stir parameters, magnetic field strength, etc., which not only increase the production difficulty but also lead to a sharp increase in equipment costs and low production efficiency; some technologies have limitations, such as the fixed magnetic field direction restricting the arrangement direction of magnetic nanoparticles, relying on copper plating to increase process complexity, and insufficient equipment adaptability and stability, making it difficult to meet the diverse and large-scale production requirements. Summary of the Invention

[0007] Aiming at the deficiencies of the prior art, the purpose of the embodiments of the present invention is to provide a magnetic field-assisted alloy centrifugal casting intelligent production line and production method.

[0008] To achieve the above purpose, the embodiments of the present invention provide the following technical solutions:

[0009] A magnetic field-assisted alloy centrifugal casting production line includes: a preparation system for preparing magnetic carbon group nanomaterial composite powder; a grinding system for grinding and compounding magnetic carbon group nanomaterial composite powder and non-magnetic metal powder to form magnetic carbon group nanocomposite powder; an ultrasonic-stirring preparation system for stirring magnetic carbon group nanocomposite powder; a material handling system for realizing visual recognition, quantitative conveying, precise weighing, and robotic arm positioning and feeding of materials through automated closed-loop control; a cold pressing and forming system for preparing magnetic carbon group nanocomposite powder into prefabricated blocks; a melting system for preparing magnetic carbon group nanocomposite material alloy melt through prefabricated blocks; and an electromagnetic centrifugal casting system for preparing workpieces of magnetic carbon group nanomaterial orderly arranged and reinforced alloys through the melt.

[0010] The preparation system converts chalcogen nanomaterials into oxidized chalcogen nanomaterial powders through multi-step chemical treatments (low-temperature oxidation, medium-temperature reaction, hydrolysis, washing and drying), and then prepares magnetic chalcogen nanomaterial composite powders through precursor dispersion, hydrothermal synthesis and post-treatment. This process endows the materials with magnetism by using chemical reactions and maintains the nanostructure characteristics of chalcogen materials, laying a foundation for subsequent composites.

[0011] The grinding system realizes the efficient composite of magnetic chalcogen nanomaterials and non-magnetic metal powders. Through the action of mechanical force, the two materials are evenly dispersed in three-dimensional space. With the help of the high specific surface area and excellent mechanical properties of magnetic chalcogen nanomaterials, the strength and wear resistance of the metal matrix are improved, and the problem of uneven dispersion in traditional mixing methods is solved.

[0012] The ultrasonic-stirring preparation system introduces ultrasonic cavitation effects during the stirring process to strengthen the dispersion effect of ternary materials (magnetic chalcogen nanomaterials, non-magnetic metal powders, solvents). The high-frequency vibration of ultrasonic waves generates a large number of tiny bubbles in the liquid. The growth, contraction and collapse of the bubbles produce strong local impacts and microjets, breaking up the agglomerates and achieving nanoscale dispersion. At the same time, vacuum drying is combined to remove the solvent, obtaining uniform magnetic nanocomposite powders with the advantages of enhanced conductivity of chalcogen materials, magnetic response of magnetite and heat conduction of the metal matrix.

[0013] The material handling system realizes full-process closed-loop automatic control through a PLC controller: after an industrial camera identifies the material, it triggers the suction machine to start. The material enters the pipeline through a trapezoidal feed inlet and is transported to the hopper. After the hopper position sensor monitors that the material height reaches the standard, the solenoid valve is opened to regulate the feeding flow. The six-axis robotic arm accurately receives the material based on the end weighing sensor and visual positioning data. After the weighing reaches the standard, the valve is closed. The robotic arm carries the material and moves to the cold pressing die through trajectory planning to complete the feeding. Finally, the weighing feedback triggers the robotic arm to return and the solenoid valve to restart, forming an intelligent control cycle from detection, transportation, quantitative weighing, precise transfer to die feeding.

[0014] The material handling system consists of a material suction machine and a six-axis robotic arm. The material suction machine includes a trapezoidal feeding inlet, a high-pressure wind-electric motor, a feeding pipe, an electromagnetic control valve, a hopper, an end effector, a vision sensor, a position sensor, a weighing sensor, a feeding pipeline, an industrial camera, and a weighing pan. After the industrial camera identifies the material, it triggers the high-pressure wind-electric motor to drive the material suction machine to start. The material is transported to the hopper through the trapezoidal feeding inlet. When the position sensor monitors that the material level reaches the standard, the solenoid valve is opened to adjust the feeding flow rate. Based on the feedback from the position and proximity sensors, the six-axis robotic arm adjusts the joint motors in real time by the servo driver, so that the end effector can accurately receive a quantitative amount of material (the weighing sensor monitors the accuracy of ±0.5%). After reaching the standard, the valve is closed. The vision sensor guides the robotic arm to transfer the material to the cold pressing die according to the trajectory. After the feeding is completed, the robotic arm returns to its original position and the solenoid valve restarts, forming a full-process automation control of "vision recognition - dynamic feeding - robotic arm positioning - weighing and feeding - reset cycle", realizing the efficient and accurate coordination of material transportation, metering, transfer, and forming.

[0015] The cold pressing forming system presses the magnetic nanocomposite powder into a high-density preform under mechanical pressure. The quality of the preform and the addition ratio of the alloy melt are precisely controlled to achieve precise regulation of the material properties. The dense preform structure is conducive to forming a good interfacial bond with the alloy melt subsequently, improving the overall performance and reliability of the composite material, ensuring uniform dispersion of the material during high-temperature melting, and enhancing the stability of the material properties.

[0016] The melting system uses the synergistic effect of induction heating and mechanical stirring to melt the preform into an alloy melt. The induction coil generates an alternating magnetic field, causing the material in the crucible to be heated and melted. At the same time, the stirring impeller rotates vertically to ensure uniform mixing of the preform and the alloy melt, promoting interfacial fusion, enhancing the material uniformity and the interfacial bonding force between phases, realizing the optimized regulation of composition and properties, and meeting the requirements for large-scale preparation of high-performance metal matrix composites.

[0017] In the electromagnetic centrifugal casting system, the core component, a concentric cylindrical mold, rotates at high speed inside the outer shell. The radial electromagnetic device generates a magnetic field, enabling the magnetic carbon group nanomaterials to achieve three-dimensional orderly arrangement under the synergistic action of centrifugal force, electromagnetic force, gravity, and buoyancy, enhancing the alloy performance. The vacuum device prevents the melt from oxidizing, the temperature control device precisely controls the mold temperature, and the demolding device ensures the smooth demolding of the casting. Finally, a workpiece of an alloy enhanced by the orderly arrangement of magnetic carbon group nanomaterials is prepared, breaking through the technical bottleneck of uneven distribution of the reinforcing phase in traditional centrifugal casting.

[0018] Optionally, the grinding system includes a first base and a transmission device, a grinding device, and a belt conveyor arranged on the first base. The magnetic carbon group nanomaterials and non-magnetic metal powders are placed in the grinding machine. The transmission device drives the grinding device to rotate for grinding. The head end of the belt conveyor is arranged on the lower side of the grinding device, and the tail end of the belt conveyor is located on the upper side of the ultrasonic-stirring preparation system.

[0019] The control system is the core control hub. By means of its internal PLC controller, frequency converter, contactor, human-machine interaction touch screen, time relay, etc., it realizes the full-process automatic closed-loop control of the grinding system, ultrasonic-stirring preparation system, material handling system, cold pressing and forming system, and melting system, and finally achieves the automatic and precise control of the whole process of material from detection, feeding, transportation to mold entry.

[0020] The control system is a highly integrated central hub with a PLC controller as the core. By integrating a frequency converter, contactor, human-machine interaction touch screen, time relay, and multi-modal sensor network, the human-machine interaction touch screen, digital sensor interface, and industrial Ethernet module are integrated into the cabinet. The human-machine interaction touch screen is installed on the front panel and interacts with the PLC controller in real time. A hierarchical closed-loop control architecture is constructed through the industrial Ethernet and field bus; after the PLC controller analyzes the sensor data, it outputs a speed regulation command to the frequency converter via the industrial bus and drives the contactor to switch the device state. The touch screen monitors the process curve in real time and supports parameter revision. The modular I / O component and edge computing unit achieve local decision-making, combined with the Internet of Things module to remotely synchronize data, and finally complete the full-process automatic closed-loop of material from identification, transportation, dynamic regulation to precise mold entry, with high response speed, multi-system coordination, and scalability, fully adapting to the needs of intelligent manufacturing.

[0021] The grinding system provides a stable support platform for the transmission device, grinding device, and belt conveyor through the first base. The transmission device drives the movement of the grinding medium (such as steel balls) in the grinding device, generating mechanical collision and grinding force, enabling the efficient compounding of magnetic carbon group nanomaterials and non-magnetic metal powders in the grinding machine. The head end of the belt conveyor is located under the grinding device, facilitating the reception of the ground material, and the tail end extends to the upper side of the ultrasonic stirring preparation system, realizing the automatic transportation of the material, reducing manual intervention, improving production efficiency, ensuring the smooth flow of the material between systems, and guaranteeing the continuity and stability of the entire production line.

[0022] Optionally, the ultrasonic-stirring preparation system includes an operation platform, a vacuum drying oven, a storage rack, a stirring device, a vacuum pump, and a material transporter. The storage rack is arranged on the operation platform, the stirring device is arranged above the storage rack, the vacuum drying oven is arranged below the storage rack, the head end of the material transporter is arranged below the vacuum drying oven, and the vacuum pump is connected to the stirring device and the vacuum drying oven through a vacuum tube.

[0023] All components of the ultrasonic stirring preparation system work together. The storage rack provides an installation position for the stirring device on the operation platform. The vacuum drying oven is located below the storage rack and is used to remove solvents. The head end of the material transport machine is located below the vacuum drying oven and is responsible for transporting the dried materials to the subsequent processes. The vacuum pump is connected to the stirring device and the vacuum drying oven through a vacuum tube to create an oxygen-free environment and prevent the oxidation of materials. The stirring device combines the cavitation effect of the ultrasonic generator and the shear flow field of the stirring impeller to achieve efficient dispersion of the ternary material, improve the mixing uniformity, ensure the stable quality of the finally obtained magnetic nanocomposite powder, meet the requirements of subsequent cold pressing and melting processes, and play a key role in improving the product quality and performance consistency of the entire production line.

[0024] Optionally, the production line further includes a grasping system. The grasping system includes a linear guide rail, a moving platform, a robotic arm, and a robotic claw. The moving platform is slidably mounted on the linear guide rail. The robotic arm is mounted on the moving platform. The robotic claw is mounted at the end of the robotic arm. The robotic claw includes a push-pull rod, a claw wrist, and clamping jaws. The claw wrist is fixed. One side of the inner end of the clamping jaw is rotatably connected to the claw wrist, and the other side of the inner end of the clamping jaw is rotatably connected to the push-pull rod. The push-pull rod moves along its length to drive the clamping jaw to swing.

[0025] The grasping system uses the linear guide rail as the running track of the moving platform. The first servo motor drives the moving platform to linearly displace along the guide rail to provide a position adjustment function for the robotic arm. The robotic claw is mounted at the end of the robotic arm, and its internal structure is ingeniously designed. When the push-pull rod moves along its length, it drives the clamping jaw to swing through the lever principle to achieve grasping and releasing actions. The fixed claw wrist ensures the overall stability of the robotic claw. The rotational connections of the inner end of the clamping jaw with the claw wrist and with the push-pull rod endow the clamping jaw with flexible opening and closing capabilities, improving the automation level and production efficiency of the production line.

[0026] Optionally, the melting system includes a high-temperature melting furnace. The high-temperature melting furnace includes a shell, a crucible, a stirring impeller, and a stirring shaft. An annular cavity is formed between the shell and the crucible. An induction coil is arranged in the annular cavity. The space of the annular cavity outside the induction coil is filled with an insulator. The crucible is a W-shaped crucible. The stirring shaft is rotatably mounted in the crucible. The stirring impeller is mounted on the stirring shaft.

[0027] An induction coil is arranged in the annular cavity between the housing and the crucible in the melting system, and the outside is filled with an insulator, which not only realizes efficient heating but also ensures safety. The W-shaped crucible increases the heating area and promotes the uniform mixing of the preform and the alloy melt. The combination of the stirring shaft and the stirring impeller is driven by a DC brushless motor to generate a vertical rotating shear force, further strengthening the mixing effect and ensuring the uniform composition of the molten slurry. The hydraulic strut controls the opening and closing of the furnace cover for convenient operation. The second solenoid valve precisely controls the discharge of the feeding pipe to achieve precise control of the melting process, providing high-quality alloy molten slurry for the electromagnetic centrifugal casting system, which is a key link to ensure the performance of the final casting.

[0028] Optionally, the production line further includes a feeding system and a handling system. The feeding system includes a gantry lifting and hoisting robot and a mechanical claw, and the mechanical claw is connected to the end of the operating arm of the gantry lifting and hoisting robot; the handling system includes an XY-axis moving platform and a second linear guide rail, and the XY-axis moving platform is installed on the second linear guide rail.

[0029] The gantry lifting and hoisting robot is fixed to the third base by bolts, and the third base is anchored to the floor to ensure the stable operation of the system. The mechanical claw is connected to the end of the operating arm. With the help of visual positioning technology and three-dimensional moving ability, it can accurately identify the position of the preform and place it into the melting system, ensuring the uniform dispersion and interface combination of materials during the high-temperature melting process, and improving the stability of the composite material preparation process. The handling system includes an XY-axis moving platform and a second linear guide rail. The moving platform is installed on the guide rail and can move flexibly in the plane. It is responsible for transporting the processed workpieces to the designated location, realizing the efficient flow of materials between the various workstations of the production line, reducing the labor intensity of workers, improving the production efficiency and automation level, and is an important logistics link connecting the various systems and ensuring the smooth operation of the production line.

[0030] Optionally, the electromagnetic centrifugal casting system includes: an electromagnetic centrifugal casting device, a driving device, an electromagnetic device, and a vacuum device; the electromagnetic centrifugal casting device includes a housing and a concentric cylindrical mold, the concentric cylindrical mold is rotatably installed in the housing, the concentric cylindrical mold includes an outer cylinder and an inner cylinder, the outer cylinder is sleeved outside the inner cylinder, there is an accommodating cavity between the housing and the outer cylinder, and a working cavity is formed between the outer cylinder and the inner cylinder; the driving device is used to drive the concentric cylindrical mold to rotate, the electromagnetic device is arranged radially in the accommodating cavity to generate a magnetic field, and the vacuum device is connected to the housing to evacuate the air.

[0031] The electromagnetic centrifugal casting system is the core part of the entire production line, and each subsystem works together to achieve precision casting. In the electromagnetic centrifugal casting device, the outer shell provides protection and support for the concentric cylindrical mold, and the mold rotates at high speed to generate centrifugal force. The driving device provides power for the rotation of the mold and transmits the power through components such as the gearbox and straight bevel gear pair to ensure stable rotation. The electromagnetic device is radially arranged in the accommodating cavity to generate a uniform magnetic field, enabling the magnetic carbon group nanomaterials to be orderly arranged in the molten slurry. The vacuum device extracts the air inside the outer shell to prevent the melt from oxidizing and ensures the surface quality and internal tissue properties of the casting. All components cooperate closely. Under the combined action of centrifugal force and electromagnetic force, the alloy molten slurry is evenly filled and solidified in the mold, realizing the three-dimensional orderly distribution of the magnetic carbon group nanomaterials, significantly improving the properties such as the hardness, wear resistance, and fatigue strength of the casting, and meeting the industrial production requirements of high-precision wear-resistant alloy components.

[0032] Optionally, the electromagnetic centrifugal casting system further includes a cooling device, which includes a water tank, a water inlet pipe, a water pump, a water outlet pipe, and a ring header. The two ends of the water inlet pipe are respectively connected to the water tank and the water pump, the two ends of the water outlet pipe are respectively connected to the water pump and the ring header. The ring header includes a ring pipe, outer risers, inner risers, and nozzles. The outer risers and inner risers are both communicated with the ring pipe. The ring pipe and the outer risers are located in the cavity between the outer shell and the outer cylinder, and the inner riser is located in the inner cylinder. The nozzles are arranged on the outer risers and inner risers and are respectively oriented towards the barrel walls of the outer cylinder and the inner cylinder.

[0033] The cooling device stores cooling water in the water tank. The water inlet pipe transports the water to the water pump, and after the water pump pressurizes it, the water is transported to the ring header through the water outlet pipe. The ring pipe of the ring header is located in the cavity between the outer shell and the outer cylinder. The outer risers and inner risers are respectively communicated with the ring pipe, and the inner riser extends into the inner cylinder. The nozzles are arranged on the outer risers and inner risers, facing the barrel walls of the outer cylinder and the inner cylinder, and evenly spray the cooling water on the surface of the mold to achieve rapid cooling. After absorbing heat, the cooling water flows back to the water tank through the drain pipe for recycling, saving water resources. This cooling device can accurately control the temperature of the mold, timely remove heat during the casting process, prevent the mold from overheating and affecting the quality of the casting, ensure the mold operates at an appropriate temperature, extend the service life of the mold, guarantee the continuity of production, and play an important role in improving the dimensional accuracy and tissue uniformity of the casting.

[0034] Optionally, the electromagnetic centrifugal casting system further includes a demolding device, which includes a cylinder, a pneumatic pipeline, a pneumatic slip ring, and an air outlet pipe. The pneumatic slip ring is installed on a pedestal bearing. One end of the pneumatic pipeline is connected to an air pump, and the other end is connected to the air inlet of the pneumatic slip ring. One end of the air outlet pipe is connected to the air outlet of the pneumatic slip ring. A middle push plate is arranged between the outer cylinder and the inner cylinder, and the middle push plate can move up and down relative to the outer cylinder and the inner cylinder. The other end of the air outlet pipe is communicated with the chamber on the lower side of the middle push plate.

[0035] The pneumatic cylinder serves as the power source and is connected to a pneumatic slip ring via pneumatic piping. The pneumatic slip ring is mounted on a bearing block, enabling air flow during rotation. One end of the air outlet pipe is connected to the air outlet of the pneumatic slip ring, and the other end is connected to the chamber under the intermediate push plate. The intermediate push plate is located between the outer and inner cylinders and can be raised and lowered relative to each other. During operation, an air pump inflates the chamber under the intermediate push plate through the pneumatic piping, generating pressure that propels the intermediate push plate upward, facilitating subsequent handling and transport of castings.

[0036] An embodiment of the present invention further provides a production method of the magnetic field-assisted alloy centrifugal casting intelligent production line as described above, comprising the following steps:

[0037] The carbon family nanomaterials are oxidized, reacted and hydrolyzed to introduce oxygen-containing functional groups, improve the surface properties of the materials, enhance the binding ability with the magnetic precursor, and obtain oxidized carbon family nanopowders.

[0038] The carbon oxide nanopowder is mixed with a magnetic precursor, and subjected to a hydrothermal synthesis treatment. The chemical reaction is promoted under a high temperature and high pressure hydrothermal environment so that the magnetic substance is evenly loaded on the surface of the carbon nanomaterial to form a magnetic carbon nanocomposite powder.

[0039] Magnetic carbon nanocomposite powder and non-magnetic metal powder are added to the grinding system in proportion, and ball milling composite treatment is achieved by mechanical collision to break the agglomerates, so that the two materials are evenly dispersed in three-dimensional space and the composite effect is improved.

[0040] The ball-milled mixture is transported to an ultrasonic stirring preparation system, and a solvent is added to form a slurry. With the help of the strong local impact and micro-jet generated by ultrasonic cavitation and the macroscopic mixing force generated by mechanical shearing, nano-scale dispersion is achieved synergistically to improve mixing uniformity.

[0041] The dispersed slurry is vacuum dried to remove the solvent and prevent oxidation and impurities from mixing. With the help of the end effector to take over the quantitative material (weighing sensor monitors ±0.5% accuracy), the robotic arm transfers the material to the cold pressing mold along the trajectory. In the cold press, the dried powder is pressed into prefabricated blocks, giving the material a preliminary shape and a certain strength to prepare for subsequent smelting.

[0042] The prefabricated blocks are placed into the melting system, and high-temperature smelting is used to melt the prefabricated blocks into alloy melts. At the same time, mechanical stirring ensures that the melt composition is uniform, promoting full mixing of materials and interface fusion.

[0043] The melt is injected into the electromagnetic centrifugal casting system, and the radial electromagnet array is started to generate a uniform magnetic field, driving the concentric cylindrical mold to rotate at high speed. The centrifugal force makes the melt evenly fill the mold cavity. The cooling system is synchronously controlled to adjust the mold temperature to achieve rapid solidification. The magnetic carbon nanomaterials are arranged in an orderly manner under the action of the magnetic field and centrifugal force, enhancing the alloy performance.

[0044] After the casting is cooled to the demoulding temperature, the casting is ejected by the demoulding device. The surface of the demoulded casting is cleaned, polished and other treatments are carried out to remove surface defects and impurities, and then it is transferred to the finished product area to complete the whole production process. Finally, an alloy workpiece with excellent performance and orderly arrangement of magnetic carbon group nanomaterials is obtained, meeting the market demand for high-precision wear-resistant alloy components.

[0045] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0046] 1. In the intelligent production line for magnetic field-assisted alloy centrifugal casting, the preparation system prepares magnetic carbon group nanocomposite powder through processes such as low-temperature oxidation and hydrothermal synthesis, and its surface modification enhances the interfacial bonding force with the metal matrix. The grinding system uses steel ball collision to achieve three-dimensional dispersion and compounding of magnetic carbon group nanomaterials and non-magnetic metal powders. The ultrasonic-stirring preparation system combines mechanical shear and ultrasonic cavitation effects to improve the dispersion uniformity of nanoparticles in the solvent. The cold pressing and forming system presses the composite powder into high-density prefabricated blocks and precisely controls the addition ratio of the alloy melt. The melting system promotes the melting of the prefabricated block through the synergistic action of induction heating and mechanical stirring. The electromagnetic centrifugal casting system dynamically regulates the arrangement of nanoparticles through an electromagnetic array, and combines centrifugal force to inhibit particle agglomeration, solving the technical problem of uneven distribution of nanoparticles in traditional centrifugal casting, and enabling large-scale production, breaking through the bottleneck of traditional processes, and opening up a new path for realizing efficient and low-cost industrial production.

[0047] 2. Aiming at the problem of uneven dispersion and poor effect of magnetic carbon group nanoparticles in the alloy solution, the present invention adopts an optimized preparation process for magnetic nanocomposites and conducts auxiliary dispersion multiple times, improving the binding rate of carbon group nanoparticles and magnetite and the uniform dispersion of carbon group nanoparticles coated with magnetite in the alloy solution, solving the problem of particle agglomeration, improving the problem of non-uniform properties of the composite material, and breaking through the limitations of traditional processes.

[0048] 3. The present invention adopts an intelligent pipeline control system, which can automatically complete processes such as mold preparation, pouring of molten metal, and demoulding of castings. The production efficiency is significantly improved through seamless connection of links. The system real-time monitors key parameters such as the temperature of molten metal, centrifugal speed, and cooling speed through intelligent sensors, and automatically adjusts immediately once the parameters deviate from the set values, effectively avoiding casting defects such as shrinkage cavities and porosity, and ensuring the quality stability of products. After adopting this system, the number of operators is reduced to 3-5 people, achieving simultaneous improvement of production efficiency and product qualification rate while reducing labor costs.

[0049] 4. The present invention realizes the multi-field cooperation of electromagnetic force and centrifugal force through dynamic regulation of the circumferential electromagnet array, effectively solves the problems of aggregation and uneven distribution of magnetic nanoparticles, significantly improves the material performance and production efficiency, and is applicable to the industrial production of high-precision wear-resistant components.

[0081] The first base Ⅱ-1 is fixed to the floor by bolts. The transmission device Ⅱ-2, the guiding and supporting device Ⅱ-3, the grinding device Ⅱ-4, the bearing base Ⅱ-5, and the climbing belt conveyor Ⅱ-7 are fixed to the first base Ⅱ-1 by bolts. The bearing base Ⅱ-5 and the guiding and supporting device Ⅱ-3 provide stable support for the grinding machine Ⅱ-4-1 to operate smoothly. The magnetic carbon group nanomaterials and non-magnetic metal powders are placed in the grinding machine Ⅱ-4-1 according to the ratio. The transmission device Ⅱ-2 drives the steel balls Ⅱ-4-5 in the grinding machine Ⅱ-4-1 through a stepping motor to achieve uniform dispersion. The control system Ⅰ is equipped with a human-machine interactive touch screen. The running time and rotation speed parameters are set through the touch screen. The touch screen is connected to the PLC controller through communication interfaces such as RS-485 and Ethernet to transmit the parameters to the PLC controller. The frequency converter receives the rotation speed command output by the PLC controller to drive the stepping motor to operate, realizing precise adjustment of the rotation speed of the grinding device Ⅱ-4 and providing corresponding rotation speeds for different requirements. The PLC controller internally integrates a time relay, and the running duration of the grinding device Ⅱ-4 is precisely controlled according to different requirements by setting time parameters. After reaching the set time, a control signal is output to stop the grinding machine and a control signal is output to the solenoid valve to control the valve actuator Ⅱ-6 to open the valve. At the same time, the touch screen displays the running state of the equipment in real time, forming an automated dispersion processing system integrating parameter setting, precise control, and status monitoring. The fixed baffle Ⅱ-8 and the sloping belt conveyor Ⅱ-7 are fixed by bolts. The valve actuator Ⅱ-6 is used to open and close the grinding machine. The climbing belt conveyor Ⅱ-7 is aligned with the discharge port of the valve actuator Ⅱ-6 and is responsible for material transportation. When the valve actuator Ⅱ-6 opens the valve, the material falls onto the belt conveyor Ⅱ-7. A through-beam photoelectric sensor is installed at the aligned position of the discharge port of the valve actuator Ⅱ-6 and the belt conveyor Ⅱ-7. Its transmitter and receiver are respectively fixed on both sides of the belt conveyor Ⅱ-7 and are connected to the PLC controller. When the material passes through the belt conveyor Ⅱ-7, the material blocks the light beam emitted by the photoelectric sensor, and the photoelectric sensor outputs a material-in-place signal to the PLC controller. After receiving the signal, the PLC controller triggers the relay to start the belt conveyor Ⅱ-7 to rise to the top for discharging, and at the same time triggers the time relay to start operating. After reaching the set time, the belt conveyor Ⅱ-7 stops running, realizing the interlock control between the material transportation and the ultrasonic-stirring preparation system Ⅲ process, and ensuring the accurate feeding of the material into the ultrasonic-stirring preparation system Ⅲ.

The support column IX-30 is welded to the preset position of the machine body shell IX-19-23. The hinge column IX-24 is aligned and connected with the hole position of the support column IX-30. The inner ring of the deep groove ball bearing IX-25 is tightly sleeved on the smooth journal part of the hinge column IX-24 and connected through interference fit to form a rotatable fulcrum. One end of the steel wire rope IX-26 is fixed to the hoisting drum IX-28, and the other end is connected to the fixed column IX-22, realizing the winding and unwinding action through the rotation of the hoisting drum IX-28. The elastic locking pin IX-27 is inserted into the pin hole of the output shaft of the second servo motor IX-29 to prevent axial or radial movement. The hinge column IX-24 is installed in the upper groove of the machine body shell IX-20-23. The butterfly hinge IX-24 passes through the hinge column IX-24 for mating connection to realize rotation. One end is connected to the machine body shell IX-19-23, and the other end is connected to the protective cover IX-20, realizing 360° free rotation to meet the opening and closing of the protective cover IX-20 and the working condition adjustment requirements.

[0104] The vacuum device consists of a rotary vane vacuum pump IX-34, a contactor IX-16, a vacuum tube IX-32, a machine body shell IX-19-23, and a third base IX-41. The rotary vane vacuum pump IX-34 is fixed to the third base IX-41 by bolts. The vacuum tube IX-32 is connected to the rotary vane vacuum pump IX-34 by bolts. The vacuum tube IX-32 is connected to the connection hole of the machine body shell IX-19-23 by welding. The opening and closing of the rotary vane vacuum pump are controlled by the contactor IX-16, realizing no contact between the melt and air, effectively avoiding the occurrence of melt oxidation, thus greatly reducing the oxidation inclusion defects in the workpiece and improving the quality of the workpiece.

[0105] The control system consists of a PLC controller IX-36, an infrared thermal imager IX-19-16, a line structured light sensor IX-19-5, a second pressure sensor IX-19-4, and a second temperature sensor IX-19-22; the infrared thermal imager IX-19-16 is installed at the middle position inside the body shell IX-19-23, and is used to check whether there are defects such as cracks, pores, or uneven thickness in the outer cylinder IX-19-12 and the inner cylinder IX-19-13; the line structured light sensor IX-19-5 is installed at the bottom of the outer cylinder IX-19-12, and is used to detect the gap between the outer cylinder IX-19-12 and the inner cylinder IX-19-13 and the double bolt hole flange IX-19-2; the second pressure sensor IX-19-4 is installed in the groove of the double bolt hole flange IX-19-2, and is used to detect the content of the molten slurry; the PLC controller IX-36 is installed on the XY-axis moving platform by bolts; the second temperature sensor IX-19-22 is installed at the bottom of the protective cover IX-20 by bolts, and is used to detect the temperature of the molten slurry and transmit the signal to the PLC controller. After processing and analysis, the cooling device is controlled to cool down in real time. The PLC controller, frequency converter, contactor, infrared thermal imager, line structured light sensor, second pressure sensor, second temperature sensor, second servo motor, fourth solenoid valve, fifth solenoid valve, vibrator, rotary vane vacuum pump, and stepping motor are all processed and analyzed through the signals fed back by the sensors with the PLC controller, and then controlled.

[0106] It can be seen from Figure 21 that the handling system X consists of an XY-axis moving platform X-1, a second laser ranging sensor X-2, anchor bolts X-3, a second linear guide X-4, and a first servo motor VI-3; the second linear guide X-4 is fixedly connected to the floor through the anchor bolts X-3, and the second laser ranging sensor X-2 is installed at the center of both ends of the second linear guide X-4 to monitor the moving position; the first servo motor VI-3 drives the precision ball screw pair to convert the rotational motion into the linear displacement of the XY-axis moving platform X-1; after the electromagnetic centrifugal casting is completed, the grasping system VI and the handling system X work together. The XY-axis moving platform X-1 moves along the pre-set route to transport the electromagnetic centrifugal casting system IX to the unloading position, and then the grasping system VI moves to the corresponding position under precise control, and takes out the centrifugally cast workpiece from the electromagnetic assisted centrifugal casting system IX and places it at the designated position.

[0107] The magnetic carbon group nanomaterials are magnetic nanoparticle-reinforced alloy materials such as graphene-coated iron oxide nanoparticles reinforced copper-based alloy, graphene-coated iron oxide nanoparticles reinforced aluminum-based alloy, or carbon nanotube-coated iron oxide nanoparticles reinforced aluminum-based alloy, carbon nanotube-coated iron oxide nanoparticles reinforced copper-based alloy, etc. The reinforced alloy material is a non-magnetic metal material.

[0108] In summary, through the synergistic effects of intelligent pipeline control, optimized preparation process of nanocomposites, and dynamic regulation of the electromagnetic circular array, the problem of the uniform distribution of magnetic carbon group nanoparticles is solved; the intelligent pipeline integrates vision positioning and multi-sensor feedback technology, and realizes millimeter-level positioning and grasping of prefabricated blocks and full-process digital control based on PLC multi-modal data fusion, supporting large-scale production; the optimized preparation process of nanocomposites uses surface modification to enhance the interfacial bonding force between the nano-phase and the matrix, combined with the dynamic regulation of the electromagnetic array, and synergistically inhibits the radial aggregation and surface agglomeration of particles through electromagnetic force, centrifugal force, gravity, and buoyancy, ultimately improving the hardness, wear resistance, and fatigue resistance of the alloy; this production line breaks through the technical bottleneck of uneven distribution of reinforcing phases in traditional centrifugal casting, realizes three-dimensional ordered dispersion of magnetic carbon group nanoparticles in the alloy, and is applicable to the industrial production of high-precision wear-resistant alloy components.

[0109] Example 2

[0110] In another typical implementation manner of the present invention disclosed in this embodiment, as Figure 2 、 Figure 3 and Figure 21 shown, the difference from Example 1 lies in that the grasping system VI, the feeding system VII, and the handling system X are different.

[0111] Specifically, the grasping system VI is composed of a first linear guide VI-1, a moving platform VI-2, a first servo motor VI-3, a first laser range finder VI-4, a robotic arm VI-6, a robotic gripper VI-7, and a second vision sensor VI-8; the linear guide VI-1 is fixed to the ground by bolts, and the base of the robotic arm VI-6 is connected to the moving platform VI-2 of the first linear guide VI-1 by bolts. The moving platform VI-2 is driven by the first servo motor VI-3 to achieve linear displacement; the robotic gripper VI-7 is connected to the end of the robotic arm VI-6 by through bolts. The first laser range finder VI-4 is installed at the center of both ends of the first linear guide VI-1 to monitor the moving position. The first vision sensor VI-8 is fixed to the end of the robotic arm VI-6 by through bolts to identify the target position. The first servo motor VI-3 drives a precision ball screw pair to convert the rotational motion into the linear displacement of the moving platform VI-2, and realizes precision positioning through the first laser range finder VI-4 at both ends of the first linear guide VI-1; finally, the second vision sensor VI-8 collects three-dimensional point cloud data in real time, transmits it to the PLC controller IX-36 through a wireless communication module, and realizes millimeter-level precise recognition of the pose of the prefabricated block by using multi-modal sensor fusion and depth algorithm. After real-time processing by the PLC controller IX-36, the optimal control instruction is generated to control the robotic arm VI-6 to work in coordination with the six-degree-of-freedom joint movement and the robotic gripper VI-7, thereby realizing three-dimensional space millimeter-level precise positioning and grasping operation of the cold-pressed prefabricated block, and then driving the moving platform VI-2 to the left side of the high-temperature melting furnace VI-3 for precise feeding by the first servo motor VI-3.

[0112] The handling system X consists of an XY-axis moving platform X-1, a second laser distance sensor X-2, anchor bolts X-3, a second linear guide X-4, and a first servo motor VI-3. The second linear guide X-4 is fixedly connected to the floor through the anchor bolts X-3. The second laser distance sensor X-2 is installed at the center of both ends of the second linear guide X-4 to monitor the moving position. The first servo motor VI-3 drives a precision ball screw pair to convert the rotational motion into the linear displacement of the XY-axis moving platform X-1. After the electromagnetic centrifugal casting is completed, the gripping system VI and the handling system X work together. The XY-axis moving platform X-1 moves along the pre-set route to transport the electromagnetic centrifugal casting system IX to the unloading position. Then, under the drive of the first servo motor VI-3, the precision ball screw pair of the gripping system VI converts the rotational motion into the linear displacement of the moving platform VI-2. Under the precise control of the first laser distance sensor VI-4, it moves to the corresponding position, and through the coordinated work of the robotic arm VI-6 in six-degree-of-freedom joint motion and the robotic claw VI-7, it realizes the precise positioning and gripping operation of the centrifugally cast workpiece, and places the workpiece at the designated position according to the preset process.

[0113] Example 3

[0114] This example proposes a production method for the magnetic field-assisted alloy centrifugal casting intelligent production line described in Example 1 or 2, which consists of Figure 21 As shown, place a large beaker in an ice-water bath, add concentrated H2SO4 to the beaker, add a magnetic stirrer bead, turn on the magnetic stirrer and control the temperature in the beaker to be about 0 °C. Add flaky carbon group nanomaterials, then add NaNO3, and slowly add KMnO4 while stirring. Continue stirring. After adding, start timing and stir and react on the magnetic stirrer for 90 min. The solution turns purple-green. Let it react for 30 min, and the solution remains purple-green. After the medium-temperature reaction ends, slowly add deionized water drop by drop and continuously stir for hydrolysis. The color of the solution changes from purple-green to bright yellow. Continue stirring and slowly add 30% H2O2 for treatment. Filter while it is hot. Wash the filter cake 3 times with 5% hydrochloric acid, and then wash it several times with distilled water until the pH is close to neutral. Disperse the product in water and ultrasonically treat it for 30 min to obtain a uniformly dispersed solution of oxidized carbon group nanomaterials. Place the dispersed solution in a 60 °C vacuum drying oven and dry it thoroughly to obtain a fluffy and dry oxidized carbon group nanomaterial powder.

[0115] Add the dry carbon group nanomaterial powder, FeCl3·6H2O, and sodium citrate into 20 mL of deionized water in a conical flask according to a certain proportion, and ultrasonically treat for 30 minutes to fully mix and disperse the three components evenly, and then transfer them to a high-pressure reactor. React at 200 °C for 12 hours. After the reactor is cooled to room temperature, vacuum filter, wash with absolute ethanol multiple times, and place the washed composite material in a vacuum drying oven at 50 °C for drying for 12 hours to finally obtain a black powder-like magnetic carbon group nanomaterial.

[0116] Drive the steel balls to move at high speed in the grinder by the magnetic carbon group nanomaterial through the transmission device, and use mechanical collision to realize the three-dimensional space dispersion of the magnetic carbon group nanomaterial and the non-magnetic metal powder.

[0117] Add the ternary material into the reactor. An ultrasonic generator is placed in the vacuum tank. Through the synergistic effect of the cavitation effect generated by the ultrasonic generator at the bottom of the vacuum tank and the shear flow field formed by the stirring impeller, nanoscale dispersion is achieved; subsequently, the vacuum drying oven is used to remove the solvent, and finally magnetic carbon group nanocomposite metal powder is obtained.

[0118] Press the magnetic carbon group nanocomposite metal powder into a high-density preform by a cold press. Place the pressed high-density preform on an adjustable lifting table through the coordinated cooperation of the robotic arm and robotic claw. Use the gantry lifting and hoisting robot to clamp and place the high-density preform on the adjustable lifting table into a high-temperature melting furnace.

[0119] Add an appropriate amount of non-magnetic metal into the high-temperature melting furnace, melt for a period of time, and use a stirrer to assist in mixing evenly. Add the prepared molten slurry into the electromagnetic centrifugal casting system.

[0120] As Figure 23 shown, at the beginning of centrifugal casting, the system first conducts mold installation detection. The infrared thermal imager IX-19-16 is used to check whether there are defects such as cracks, pores, or uneven thickness in the outer cylinder IX-19-12 and the inner cylinder IX-19-13; the line structured light sensor IX-19-5 detects the gap between the outer cylinder IX-19-12 and the inner cylinder IX-19-13 and the double-bolt hole flange IX-19-2 connection. The gap does not exceed 0.05 mm. Only after both detections are qualified can the operation continue; if any detection is unqualified, the system will trigger an alarm and return to the installation and inspection process until the standard is reached.

[0121] After passing the detection, the PLC controller IX-36 controls the frequency converter IX-13 through a program to adjust the direction and current magnitude of the electromagnet IX-19-10 according to the type of non-magnetic metal to be cast, and injects the magnetic carbon group nanocomposite solution into the concentric cylindrical mold; the pressure sensor IX-19-4 is installed in the groove of the double-bolt hole flange IX-19-2. Under the real-time monitoring of the pressure sensor IX-19-4, the PLC controller IX-36 determines whether the pressure value at the double-bolt hole flange IX-19-2 meets the standard (detecting the injection volume of the composite solution), and controls the stepping motor IX-33 through the contactor IX-16 to close the protective cover IX-20 and start the rotary vane vacuum pump IX-34 to extract vacuum; after an interval of 2 minutes, the PLC controller IX-36 automatically starts the electromagnetic centrifugal casting device IX-19 to run through the program control of the contactor IX-16. At the same time, the temperature sensor IX-19-22 dynamically monitors the temperature of the concentric cylindrical mold in real time. When the temperature exceeds the preset value, the fourth solenoid valve IX-37 opens, and the cooling device starts to cool down. After the temperature drops below the set value, it is closed. According to the alloy type, the PLC controller IX-36 can also adjust the rotation speed of the stepping motor IX-33 and automatically stop after completing the centrifugal casting according to the preset time.

[0122] After casting is completed, the system controls the air pump IX-6 to ventilate and demold the concentric cylindrical mold through the third solenoid valve IX-8, and starts the vibrator IX-19-19 through the contactor IX-16 to further assist in demolding for 2 minutes.

[0123] The contactor IX-16 is used to control the stepping motor IX-33 to open the protective cover IX-20. Subsequently, the PLC controller IX-36 controls the XY-axis moving platform to move along the pre-set route, transports the electromagnetic centrifugal casting system IX to the designated position, and then the clamping system moves to the corresponding position under precise control, takes out the centrifugally cast workpiece from the electromagnetic-assisted centrifugal casting system IX and places it at the designated position, and closes the protective cover IX-20. After the robot accurately places it, the platform resets to prepare for the next cycle of casting operations.

[0124] Although the above combines the drawings to describe the

[0125] specific implementation manner of the present invention, it is not a limitation on the protection scope of the present invention. Those skilled in the art should understand that based on the technical solution of the present invention, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the present invention.
