Description

Technical Field

[0001] The present invention belongs to the technical field of arc fuse additive manufacturing, and in particular relates to an accompanying heat treatment device and method for arc fuse additive manufacturing. Background Art

[0002] With the continuous advancement of aerospace technology, the demand for heterogeneous mechanical properties in large, complex structural parts is increasing. Additive manufacturing, with its bottom-up layer-by-layer accumulation of materials, offers significant advantages in the rapid manufacture of complex, special-shaped components. Wire and Arc Additive Manufacturing (WAAM), with its advantages of low equipment cost, high forming efficiency, and readily available raw materials, is particularly suitable for the integrated manufacture of large aluminum alloy components in large-scale structural parts. It has become a focus of attention in major equipment sectors such as aerospace, shipbuilding, and weapons.

[0003] WAAM components commonly suffer from non-equilibrium solidification microstructures, defects such as pores and cracks, and significant residual stresses, making it difficult for their mechanical properties to match those of conventionally heat-treated components. Large-scale additive manufacturing components often cannot undergo conventional overall heat treatment due to their large structural dimensions, making it difficult to fully implement stress relief annealing and precipitation strengthening. Existing local strengthening methods are limited by external field coupling efficiency and process adaptability, and have yet to break through the technical bottleneck of gradient performance regulation and coordinated assurance of structural integrity, greatly limiting the engineering application of the WAAM process in high-performance customized components. A search revealed patent publication number CN109513932A, which discloses an online heat treatment device and method for aluminum alloy arc additive manufacturing. While the welding torch performs additive manufacturing, a heating device simultaneously heats the printed area to prevent excessive solidification and the resulting coarse grains. While this patent allows for random heat treatment of additively manufactured components, improving the microstructure and performance of printed components, it does not perform differentiated heat treatment on the printed components, making it impossible to regulate the gradient mechanical properties of the printed components. Summary of the Invention

[0007] Furthermore, when the component needs to be heated on both sides simultaneously, the heat spreader assembly includes two heat spreaders, and a flexible heat conducting plate is provided on the inner side of each heat spreader.

[0008] Furthermore, the heat spreader is made of copper-based material, and the flexible heat conductive plate is made of flexible and variable heat conductive material.

[0009] Furthermore, the flexible and variable thermal conductive material adopts silicone-based composite material or graphite.

[0011] Furthermore, the clamping unit includes a load-bearing frame and a clamping component connected to both ends of the load-bearing frame. The clamping component includes a guide rail and two resistance clamping heads installed on the guide rail. The heat equalization component is fixedly connected to the resistance clamping head. When the component is heat treated, the two resistance clamping heads are used to move in the same direction to clamp the component, and the component is heat treated through the heat equalization component.

[0012] Furthermore, the monitoring instrument includes an infrared temperature sensor and a laser displacement sensor; The laser displacement sensor is used to perform multi-point positioning of the position of the designated heating area, and the temperature sensor is used to collect temperature data of the designated heating area of the component in real time.

[0013] The present invention also discloses an arc fuse additive manufacturing accompanying heat treatment method, which includes the following process: Slice and layer the 3D model of the component and plan the path; The positioner rotates counterclockwise, while the welding gun head of the additive equipment prints components on the substrate according to the slice layering and path planning; the subtractive equipment reduces material layer by layer according to the specified shape; After the component's deposition height reaches the designated heating height, the monitoring instrument locates the designated heating area and collects temperature data in real time, transmitting it to the control system. The control system calculates the target temperature and heating time for the heating area based on the component's mechanical properties and the positioner's rotation speed. When it is detected that the temperature of the designated heating area of the component is lower than the target temperature, the positioner is used to adjust the component posture to meet the heat treatment requirements; when the additive equipment is printing the next layer, the heat treatment equipment is turned on simultaneously to perform in-situ heat treatment of the designated heating area, as follows: The heat treatment equipment drives the heating mechanism to the heating area through the heat treatment robot according to the position of the component's designated heating area in the control system and the component's posture.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention discloses an accompanying heat treatment device for arc fuse additive manufacturing.

[0016] The present invention discloses a method for on-the-go heat treatment in arc fuse additive manufacturing. When the deposition height reaches the specified heating height, the heating area is located at multiple points through monitoring instruments, and temperature data is collected in real time and transmitted to the control system. The target temperature and heating time are calculated according to the mechanical performance requirements of the component and the rotation speed of the positioner. If the detected temperature is lower than the target value, in-situ heating is performed while adding material. The positioner adjusts the component posture so that the heating area is aligned with the heating mechanism, and the temperature of the heat spreader is raised to the target temperature. After the heating time is reached, the heating is stopped, and printing and heating are achieved in parallel, reducing waiting time. The present invention proposes a new composite forming method of "arc fuse additive manufacturing-on-the-go rapid heat treatment", which adopts a positioner-manipulator collaborative motion strategy to break through the inherent time and space constraints of traditional heat treatment processes and solve the size limitation problem of traditional integral heat treatment equipment.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following is a further detailed description with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. That is, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0020] The components described and illustrated in the drawings and embodiments of the present invention may be arranged and designed in a variety of different configurations. Therefore, the detailed description of the embodiments of the present invention provided in the following drawings is not intended to limit the scope of the claimed invention, but merely represents a selected embodiment of the present invention. All other embodiments derived by those skilled in the art based on the drawings and embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0021] It should be noted that the terms "comprises", "includes" or any other variations are intended to cover non-exclusive inclusion, so that a process, element, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to the process, element, method, article or apparatus.

[0022] like Figure 1 As shown, the present invention discloses a heat treatment method for arc fuse additive manufacturing, including additive equipment, heat treatment equipment, subtractive equipment, and a positioner. The additive equipment, subtractive equipment, and heat treatment equipment are sequentially arranged around the positioner, allowing additive, subtractive, and heating processes to proceed in a sequential manner.

[0023] The additive equipment includes a first lifting platform 1 and an additive robot 2 installed on the first lifting platform 1, and a welding gun for additive manufacturing is installed at the end of the additive robot 2; the subtractive equipment includes a second lifting platform 3 and a subtractive robot 4 installed on the second lifting platform 3, and an element for subtracting is installed at the end of the subtractive robot 4; the heat treatment equipment includes a third lifting platform 5 and a heat treatment robot 6 installed on the third lifting platform 5, and a heating mechanism 7 is installed at the front end of the heat treatment robot 6, and the heating mechanism 7 is used to perform heat treatment on a designated area of the part.

[0024] Specifically, the subtractive element generally uses a milling cutter to perform milling processing on the component to achieve the required surface quality and dimensional accuracy.

[0025] The first lifting platform 1, the second lifting platform 3 and the third lifting platform 5 all include a shell, a screw slider mechanism is installed on the shell, a drive motor is installed at the end of the screw, the slider is connected to a support frame, a base is installed on the support frame, and the base is connected to the robot.

[0026] Typically, the additive robot 2, subtractive robot 4, and heat treatment robot 6 are all industrial six-axis robots. These robots are widely used in industrial automation equipment, featuring six movable joints and capable of complex movements and manipulations in three-dimensional space. However, these robots are not limited to six-axis robots; five-axis and seven-axis robots are also acceptable.

[0027] The positioner includes a base, a substrate is placed on the base, a motor is installed inside the base, and the motor is connected to a control system. The control system controls the rotation of the motor to realize the rotation of the base.

[0028] according to Figure 2 The setting is that the positioner rotates counterclockwise, and the additive equipment, subtractive equipment and heat treatment equipment are placed in a counterclockwise order, specifically at intervals of 120 degrees, so that additive, subtractive and heating can be carried out according to the process.

[0029] like Figure 3 As shown, the present invention is designed for a heating mechanism 7, including a clamping unit and a heat equalizing assembly. The clamping unit includes a load-bearing frame 11 and a clamping component connected to both ends of the load-bearing frame 11. The clamping component includes a guide rail 8 and a resistor clamping head 9 installed on the guide rail 8. The heat equalizing assembly is fixedly connected to the resistor clamping head 9.

[0030] When a certain area of a component needs to be heated on both sides at the same time, such as Figure 3 As shown, two resistor clamping heads 9 are installed on the guide rail 8. The two resistor clamping heads 9 move in the same direction to clamp the component and perform heat treatment on the component through the heat-saturating component.

[0031] When a certain area of a component needs to be heat treated on one side, such as a cylindrical part, it can only be heated on the outside and in reverse. At this time, only one resistance clamping head 9 can be installed on the guide rail 8, and the heat-saturating component is close to the outside of the component, and the component is heat-treated through the heat-saturating component.

[0032] Specifically, the heat spreader assembly includes a heat spreader 12 and a flexible heat conductive plate 13 located inside the heat spreader 12. Generally speaking, the heat spreader 12 is made of a copper-based material plate, whose internal crystal structure and composition distribution are relatively consistent, without obvious local differences. This prevents significant heat accumulation or uneven heat dissipation during heat conduction, and promotes uniform heat distribution throughout the copper plate. However, the heat spreader 12 is not limited to copper-based materials and can also be made of aluminum-based materials, ceramic-based materials, etc.

[0033] The flexible heat-conducting plate 13 is made of flexible and deformable heat-conducting material, which can achieve self-adherence deformation with the curved surface of complex components through dynamic deformation, effectively solving the problems of uneven heat conduction and thermal deformation during in-situ heat treatment of large-sized WAAM components.

[0034] Generally, silicone-based composites and graphite are suitable flexible and adaptable thermally conductive materials. Silicone-based composites consist of a silicone matrix (temperature resistant from -50°C to 200°C) and aligned graphene / carbon nanotubes (thermal conductivity ≥ 15 W / (m·K)).

[0035] The flexible heat conducting plate 13 is close to the heat spreader 12, the heat spreader 12 is fixed on the resistor clamping head 9, and the two guide rails 8 are fixed to the load-bearing frame 11 by studs 10. The resistor clamping head 9 is connected to the heating power supply through a cable to form an electrical circuit, and the resistive heating element is integrated inside. The heat spreader 12 is rigidly connected to the heating end of the resistor clamping head 9 through a heat conduction interface to form a continuous heat conduction path. During the heating process, the electrical energy is transmitted to the resistor clamping head 9 via the cable and converted into thermal energy, which is then diffused in the plane through the heat spreader 12 and then conducted to the component through the flexible heat conduction plate 13. In order to ensure that heat can be fully transferred even on small curvature surfaces and topological structures, the resistor clamping head 9 can drive the heat spreader 12 and the flexible heat conduction plate 13 to tighten the component through the guide rail 8, and use the deformation characteristics of the flexible heat conduction plate 13 for flexible support. The heating temperature is measured by a K-type thermocouple and regulated by external control software.

[0036] The overall process Figure 1 The high-performance, integrated additive manufacturing process for large-scale scandium-containing aluminum alloy components includes pre-processing and manufacturing. Pre-processing includes model creation, print path planning, model import equipment, and print base plate placement. After the print base plate is placed on the positioner, printing begins. The positioner rotates counterclockwise, simultaneously initiating additive manufacturing. When the additively molded blank passes through the subtractive station for the first time, the subtractive equipment in that station activates and subtracts material to the specified shape.

[0037] When the deposition height of the component reaches the specified heating height, the control system analyzes and calculates the heating time and target temperature of the area to be heated in advance based on the mechanical performance requirements of the component and the rotation speed of the positioner; When the temperature sensor detects that the temperature of the component is lower than the target temperature, the heat treatment equipment starts, and the heating mechanism 7 moves the resistance clamping head 9 so that the two relative heat spreaders are clamped in the heated area of the component, and the clamping pressure is dynamically adjusted according to the component deformation feedback data to ensure that the gap between the heat spreader 12 and the contact surface of the component is no more than 0.1mm. The heat spreader 12 is heated to the target temperature, and the heating is stopped after the heating time is reached.

[0038] The present invention obtains the following through simulation: Figure 4The relationship between heating temperature, heating time and mechanical properties shown in the figure can determine the time it takes for a specific position to pass through the heating area based on the rotation speed of the positioner and the size of the heating plate during the manufacturing process, and the required heating temperature can be determined based on the required mechanical properties at the specific position.

[0039] The mechanical properties of the component require a yield strength of , the angular velocity of the positioner is The radius of the heated area from the center of the base is R, the length of the heat plate 12 is L, and the time it takes for a specific position to pass through the heating area is t. , based on the three-dimensional thermal stress finite element analysis model of the material established by simulation, according to the yield strength The function relationship between heating time and target temperature is used to calculate the target temperature required for heating. .

[0040] For example, the support base of a large rotating machinery is a large-sized cylindrical load-bearing structure used to bear the dynamic load and vibration excitation of high-speed rotating parts. Its bottom area (0-30% height) directly bears the continuous compressive stress generated by the weight of the equipment and the rotational inertia force, requiring this area to have a high yield strength (≥300MPa); its middle area (30%-70% height) is subject to the superposition of alternating bending stress and vibration harmonics, and it is necessary to balance strength and toughness to avoid brittle fracture, requiring the yield strength of this area to be greater than 260MPa; its top area (70%-100% height) is connected to the rotating part interface, and the stability of the transmission system must be guaranteed, requiring the yield strength to be greater than 200MPa; assuming its height is 200mm, when the additive height reaches 60mm, the specified area of the deposited component can be heat treated, and the mechanical properties required at a specific location require a yield strength of 300 MPa, the rotation speed of the positioner is 0.1rad / min, the radius of the area to be heated from the center of the base is 1m, the length of the heat spreader 12 is 0.5m, and the control system calculates that the required heating time is 300s and the target heating temperature is 380℃. At this time, the heat treatment equipment is turned on, and the heat treatment robot 6 is slid and debugged along the third lifting platform 5 to the designated heating area, the heat spreader 12 is heated evenly, and the designated area is heat treated.

[0041] Taking scandium-containing aluminum alloy wire as an additive material as an example, the additive manufacturing method is introduced as follows: Aluminum alloy plates are used as substrates, and scandium-containing aluminum alloy wires are used as additive materials for the metal arc welding torch; Turn on the welding gun to form a liquid molten pool on the substrate, feed the scandium-containing aluminum-magnesium alloy wire into the liquid molten pool, melt the scandium-containing aluminum alloy wire into liquid, form a protective atmosphere above the molten pool with the welding gun, and move the welding gun to solidify the molten pool into a solid state; Keep moving the welding gun to complete the first layer deposition; The welding gun is lifted by the additive robot 2 to deposit the second layer of melt on the first layer of melt; Repeatedly move and lift the welding gun to deposit layer by layer; When the height of the deposited component reaches the specified heating height, the monitoring instrument performs multi-point positioning of the designated heating area, collects temperature data of the designated heating area in real time, and transmits it to the control system. The control system calculates the target temperature and heating time of the heating area based on the mechanical properties of the component and the rotation speed of the positioner. When it is detected that the temperature of the designated heating area of the component is lower than the target temperature, the positioner is used to adjust the component posture to meet the heat treatment requirements; when the additive equipment is printing the next layer, the heat treatment equipment is turned on simultaneously to perform in-situ heat treatment of the designated heating area, as follows: The heat treatment equipment drives the heating mechanism 7 to the heating area through the heat treatment robot 6 according to the position of the component designated heating area in the control system and the posture of the component; the heating mechanism 7 moves the resistance clamping head 9 to position the heat soaking assembly in the heating area of the deposition component and dynamically adjusts the clamping pressure according to the component deformation feedback data; the heat soaking plate 12 is heated to the target temperature and the heating is stopped after the heating time is reached; Repeat the movement and lifting of the welding gun until the required size of the aluminum-magnesium alloy component is deposited.

[0042] The material addition process and the heat treatment process of the present invention do not interfere with each other and are carried out simultaneously.

[0043] To further prevent unexpected situations, the present invention adds a further logic step: if the temperature of the designated heating area of the component is detected to be higher than the target temperature, the next layer of printing is performed after the component cools to the interlayer control temperature. If the temperature is too high, printing is paused until the component cools to the interlayer control temperature, preventing deformation or structural defects caused by overheating.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of protection of the claims of the present invention.
