Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal resource recycling and additive manufacturing, and in particular to a device and method for preparing a wire for regenerative manufacturing from recycled materials. BACKGROUND

[0002] In the context of the rapid development of the aerospace industry, high-performance space vehicle components have increasingly stringent requirements for material performance. Such components are often made of expensive materials such as high-strength aluminum alloys, titanium alloys, nickel-based high-temperature alloys, and high-strength steels. They need to serve in extreme conditions for a long time, so there are almost stringent standards for core indicators such as microstructure uniformity and mechanical properties.

[0003]

[0004] However, when these high-performance components are retired due to the end of life or accidental damage, the efficient recycling of their materials becomes a major bottleneck for the industry. Traditional metal recycling processes have low efficiency and insufficient performance recovery, making it difficult to meet the precise needs of high-performance material recycling. Not only does this result in a large amount of idle and wasted valuable resources, but it also poses a potential threat to other normally moving spacecraft during their free movement in space, which contradicts the concept of sustainable development in the aerospace field. Therefore, developing efficient and environmentally friendly on-orbit recycling technologies to achieve high-quality regeneration of space vehicle component materials has become a key issue in promoting the sustainable development of the aerospace industry.

[0005] At the same time, additive manufacturing technology has shown increasing potential for application in the aerospace field due to its near-net shaping, high material utilization, and low manufacturing cost, especially for the manufacture of complex structures, personalized components, and small batches of high-performance components. However, this technology places extremely high demands on the quality of raw materials, particularly wire, which not only needs to have excellent mechanical properties but also needs to have good forming stability and wire feeding smoothness. Currently, high-quality wire that meets the standards of additive manufacturing is mostly prepared from new raw materials, resulting in high costs and severely restricting the large-scale application of additive manufacturing technology in the aerospace field.

[0006] Under this background, how to utilize discarded high-performance space vehicle components to prepare high-quality recycled wire that meets the requirements of additive manufacturing, both solving the recycling problem of discarded components and reducing the raw material cost of additive manufacturing, has become a core technical bottleneck that the industry urgently needs to break through.

DETAILED DESCRIPTION

[0043] To further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0044] As Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10As shown, a device for preparing wire rod for recycled manufacturing by using recycled materials is provided in an on-orbit space module 1; an electromagnetic smelting furnace 2, a forging press 31, a preliminary drawing mechanism 32, a high-temperature spiral roller die drawing system 4, an induction heat treatment device 5 and a low-temperature spiral roller die drawing system 6 are sequentially arranged in the on-orbit space module 1 along the material processing direction; a three-dimensional coordinate robot 11 is arranged in the on-orbit space module 1 to transfer materials between the processing equipment; wherein the high-temperature spiral roller die drawing system 4 comprises: a first central axis; a plurality of first roller die drawing units 41 evenly distributed around the first central axis; the low-temperature spiral roller die drawing system 6 comprises: a second central axis parallel to the first central axis; a plurality of second roller die drawing units 61 evenly distributed around the second central axis; the discharge port 414 of the preliminary drawing mechanism 32, the inlet and outlet ports 414 of each first roller die drawing unit 41 and the inlet and outlet ports 414 of each second roller die drawing unit 61 are all located in the same horizontal working plane; wherein the metal scrap is melted into an ingot by the electromagnetic smelting furnace 2, the ingot is forged by the forging press 31 and then drawn into a rod blank by the preliminary drawing mechanism 32, the rod blank is sequentially drawn by the plurality of first roller die drawing units 41, heat treated by the induction heat treatment device 5 and then sequentially drawn by the plurality of second roller die drawing units 61, and finally the target wire rod is formed.

[0045]

[0046] As shown in the drawings, the plurality of first roller die drawing units 41 of the high-temperature spiral roller die drawing system 4 are arranged in a spiral ascending manner along the axial direction of the first central axis, and the height difference between adjacent first roller die drawing units 41 is constant; the plurality of second roller die drawing units 61 of the low-temperature spiral roller die drawing system 6 are arranged in a spiral ascending manner along the axial direction of the second central axis, and the height difference between adjacent second roller die drawing units 61 is constant.

[0047] Through the spiral ascending design, the roller die drawing units are arranged in multiple layers in a limited space, significantly reducing the equipment footprint. The constant height difference ensures that the material gradually deforms during the drawing process, avoiding stress mutation, improving the uniformity and mechanical properties of the wire rod, and reducing the risk of cracking or breaking. The spiral ascending structure uniformly transmits the drawing force along the axial direction, reduces the stress concentration at a single point, prolongs the service life of the roller die and the transmission mechanism, and reduces energy consumption.

[0048] As shown in the drawings, the plurality of first roller die drawing units 41 of the high-temperature spiral roller die drawing system 4 are arranged in a spiral ascending manner along the axial direction of the first central axis, and the height difference between adjacent first roller die drawing units 41 is constant; the plurality of second roller die drawing units 61 of the low-temperature spiral roller die drawing system 6 are arranged in a spiral ascending manner along the axial direction of the second central axis, and the height difference between adjacent second roller die drawing units 61 is constant. Figure 9

[0049] Through the spiral ascending design, the roller die drawing units are arranged in multiple layers in a limited space, significantly reducing the equipment footprint. The constant height difference ensures that the material gradually deforms during the drawing process, avoiding stress mutation, improving the uniformity and mechanical properties of the wire rod, and reducing the risk of cracking or breaking. The spiral ascending structure uniformly transmits the drawing force along the axial direction, reduces the stress concentration at a single point, prolongs the service life of the roller die and the transmission mechanism, and reduces energy consumption.

[0050] As shown in the drawings, the plurality of first roller die drawing units 41 of the high-temperature spiral roller die drawing system 4 are arranged in a spiral ascending manner along the axial direction of the first central axis, and the height difference between adjacent first roller die drawing units 41 is constant; the plurality of second roller die drawing units 61 of the low-temperature spiral roller die drawing system 6 are arranged in a spiral ascending manner along the axial direction of the second central axis, and the height difference between adjacent second roller die drawing units 61 is constant. Figure 3 Figure 5 ​​​As shown, the high-temperature spiral roller die drawing system 4 further comprises a first guide rail arranged between adjacent first roller die drawing units 41, for connecting the discharge port 414 of the front first roller die drawing unit 41 with the feeding port 411 of the rear first roller die drawing unit 41.

[0051] The low-temperature spiral roller die drawing system 6 further comprises a second guide rail arranged between adjacent second roller die drawing units 61, for connecting the discharge port of the front second roller die drawing unit 61 with the feeding port of the rear second roller die drawing unit 61.

[0052] By arranging the first guide rail and the second guide rail, it is ensured that the material can be smoothly and continuously conveyed from the front first roller die drawing unit 41 to the rear first roller die drawing unit 41 and from the front second roller die drawing unit 61 to the rear second roller die drawing unit 61 during high-temperature and low-temperature drawing, avoiding the problems of material breakage and jamming caused by manual intervention or mechanical docking errors, and improving production efficiency.

[0053] As shown in Figure 6 The first roller die drawing unit 41 comprises a fixed support 417, the height of which is arranged to increase along the circumference of the first central axis; an upper roller die 412 and a lower roller die 413 arranged in an upper-lower opposite manner, rotatably mounted in the fixed support 417, and forming a drawing channel aligned with the horizontal working plane between the upper roller die 412 and the lower roller die 413; a first transmission gear set arranged at the same end of the upper roller die 412 and the lower roller die 413, the first transmission gear set comprising an upper driving gear 415 and a lower driving gear 416 meshing with each other and coaxially connected with the upper roller die 412 and the lower roller die 413, respectively.

[0054] Further, the side surface of the fixed support 417 is further provided with a first protective cover covering the first transmission gear, preventing gear debris from polluting the working environment.

[0055] The first roller die drawing unit 41 adopts an upper-lower opposite arrangement of the upper roller die 412 and the lower roller die 413, and a horizontal drawing channel is formed between the two, ensuring that the material remains stable and centered during drawing.

[0056] The first transmission gear set (including the upper driving gear 415 and the lower driving gear 416 meshing with each other) is coaxially connected with the roller die, realizing synchronous reverse rotation, so that the material is uniformly pressed and conveyed forward between the roller dies.

[0057] As shown in Figure 7 and Figure 8As shown, the high-temperature spiral roller die drawing system 4 further comprises a first central driving unit 48, which comprises a first driving shaft 481 arranged along the first central axis, and a plurality of first driven shafts 482 uniformly distributed along the circumference of the first driving shaft 481, each first driven shaft 482 being in perpendicular transmission connection with the first driving shaft 481 through a bevel gear set, and the outer end of the first driven shaft 482 being in transmission connection with the lower roller die 413.

[0058] As a first embodiment of the first central driving unit 48 in the present application, the first central driving unit 48 further comprises a first motor 483, and the output shaft of the first motor 483 being in transmission connection with the first driving shaft 481.

[0059] A first large bevel gear 484 is arranged on the first driving shaft 481, and a first small bevel gear 485 is arranged on the inner end of each first driven shaft 482, the first small bevel gear 485 being in meshing connection with the first large bevel gear 484, and the diameter of the first small bevel gear 485 increasing from the circumference of the first central axis, so as to adapt to the first roller die drawing units 41 with drawing channel height increasing in turn, and transmit the torque to the lower roller dies 413 at different heights.

[0060] As a second embodiment of the first central driving unit 48 in the present application, the first central driving unit 48 further comprises a second motor 483, and the output shaft of the second motor 483 being in transmission connection with the first driving shaft 481. A second large bevel gear 486 is arranged on the first driving shaft 481, and a second small bevel gear 487 is arranged on the second large bevel gear 486 along the circumference of the second large bevel gear 486, the second small bevel gear 487 being in meshing connection with the second large bevel gear 486, and the second small bevel gear 487 being in transmission connection with the first driven shaft 482 through a universal shaft 488, so as to transmit the torque to the lower roller dies 413 at different heights.

[0061] The low-temperature spiral roller die drawing system 6 further comprises a second central driving unit 68, which has the same structure as the first central driving unit 48.

[0062] As shown in the drawings, Figure 3 As shown, the high-temperature spiral roller die drawing system 4 further comprises a high-temperature wire disc 46 arranged at the end of the high-temperature spiral roller die drawing system 4, for winding the wire material drawn through each first roller die drawing unit 41.

[0063] As shown in the drawings, Figure 5 As shown, the low-temperature spiral roller die drawing system 6 further comprises a moving wire disc 66 arranged at the end of the low-temperature spiral roller die drawing system 6, for winding the wire material drawn through each second roller die drawing unit 61.

[0064] An on-orbit device for manufacturing wire rod with recycled material, comprising an on-orbit space module 1 carrying a wire rod manufacturing device, an electromagnetic smelting furnace 2, a forging press 31, a preliminary drawing mechanism 32, a high-temperature spiral roller die drawing system 4, an induction heat treatment device 5, a low-temperature spiral roller die drawing system 6, a solar panel 7, a space power supply 8, a propulsion module 9, and a three-dimensional coordinate robot 11. The electromagnetic smelting furnace 2, the forging press 31, the preliminary drawing mechanism 32, the high-temperature spiral roller die drawing system 4, the induction heat treatment device 5, the low-temperature spiral roller die drawing system 6, and the space power supply 8 are horizontally installed inside the on-orbit space module 1, the solar panel 7 is located on both sides of the on-orbit space module 1, and the propulsion module 9 is located at the rear of the on-orbit space module 1. The electromagnetic smelting furnace 2, the forging press 31, and the preliminary drawing mechanism 32 are installed on the same side inside the on-orbit space module 1,

[0065] The discharge end of the preliminary drawing mechanism 32 is co-planar with the first roller die drawing unit 41 of the high-temperature spiral roller die drawing system 4, and the feeding / discharge ends are concentric. The induction heat treatment device 5 is positioned above the first roller die drawing unit 41 of the high-temperature spiral roller die drawing system 4 by bolts. The low-temperature spiral roller die drawing system 6 is located to the right of the high-temperature spiral roller die drawing system 4. The second roller die drawing unit 61 of the low-temperature spiral roller die drawing system 6 is co-planar with the first roller die drawing unit 41 of the high-temperature spiral roller die drawing system 4, and the feeding / discharge ends are concentric. The on-orbit space module 1 is used to provide a work platform for other modules. The solar panel 7 and the space power supply 8 are used to provide power energy for other modules. The propulsion module 9 is equipped with a vector propulsion device for adjusting the pose of the on-orbit device.

[0066] The electromagnetic smelting furnace 2 is internally provided with a mechanical / electromagnetic dual stirring device to ensure metal smelting in a microgravity environment. The smelting temperature can reach 1800℃, and the maximum smelting quantity per time is 12kg.

[0067] Due to the space microgravity environment, after the metal is melted, it will not sink to the bottom, but will float around in the tank,

[0068] Therefore, a mechanical / electromagnetic dual stirring device needs to be added during the smelting process to improve the uniformity of the melt. In the final stage of smelting, the tank can be rotated around its support to use centrifugal force to make the internal melt sink to the bottom to form a whole smelting ingot.

[0069] The forging press 31 and the preliminary drawing mechanism 32 cooperate to upset and elongate the smelting ingot obtained from the electromagnetic smelting furnace 2. The forging press 31 can provide a hot forging environment with a maximum temperature of 1100℃ and a forging pressure of 10 tons.

[0070] After the alloy ingot cools to a suitable temperature for hot forging (which varies depending on the material), the three-dimensional coordinate robot 11 opens the furnace lid of the electromagnetic melting furnace 2, removes the steel ingot, and places it into the forging press 31 to begin hot forging, resulting in a...

[0071] A round bar is then fed into the preliminary drawing mechanism 32 (a four-roller drawing device) to initially draw it into a thin bar. (The material flow process is assisted by a three-dimensional coordinate robot 11.)

[0072] The high-temperature spiral roller drawing system 4 is installed above the first spiral gradient platform 47. A first central drive unit 48 is installed at the center of the first spiral gradient platform 47. Five first roller drawing units 41 spirally ascend around the first central drive unit 48. The roller die aperture of the five first roller drawing units 41 decreases step by step. The five first roller drawing units 41 are powered by the first central drive unit 48. The included angle between the first roller drawing units 41 is 60°. The inlet / outlet of the first roller drawing units 41 is connected by a first guide rail. A high-temperature wire disc 46 is installed at the highest point of the first spiral gradient platform 47.

[0073] The induction heat treatment device 5 is located directly above the first roller drawing unit 41. The induction heat treatment device 5 is positioned by fixing the base 52 with screws. One side of the base 52 is connected to the wire inlet 51, the right side of the wire inlet 51 is connected to the induction heating device 53, and the other side of the base 52 is connected to the wire outlet 55.

[0074] The low-temperature spiral roller drawing system 6 is installed above the second spiral gradient platform 67. A second central drive unit 68 is installed at the center of the second spiral gradient platform. The second roller drawing unit 61 spirals upward around the second central drive unit 68. The roller die aperture of the second roller drawing unit 61 decreases step by step. The second roller drawing unit 61 is powered by the second central drive unit 68. The included angle between the second roller drawing units 61 is 60°. The inlet / outlet of the second roller drawing unit 61 is connected by a second guide rail. A movable wire disc 66 is installed at the highest point of the second spiral gradient platform 67.

[0075] The first roller die drawing unit 41 includes a feed inlet 411, which is mounted on a fixed bracket 417 by screws. Opposite to the feed inlet 411 is a discharge outlet 414, which is coaxial with the feed inlet 411. An upper roller die 412 and a lower roller die 413 are installed between the feed inlet 411 and the discharge outlet 414. The upper roller die 412 and the lower roller die 413 are tangent, and their tangent lines are collinear with the axes of the feed inlet 411 and the discharge outlet 414. An upper drive gear 415 and a lower drive gear 416 are installed on the other side of the fixed bracket 417. It should be noted that the assembly relationship of any other second roller die drawing unit 61 in this device is the same as that of the first roller die drawing unit 41.

[0076] like Figure 2 As shown, after the alloy structural parts are crushed and sorted, they are loaded into the electromagnetic melting furnace 2 by a three-dimensional coordinate robot 11 for melting. The melting furnace temperature is set at 1600℃±30℃, and the melting is repeated 3 times to obtain a pure alloy ingot. Subsequently, the alloy ingot is placed in the forging press 31 and the preliminary drawing mechanism 32 for blank forging and preliminary drawing. The hot forging temperature is set at 800±30℃, and the alloy ingot is repeatedly upset and drawn 8 times using a forging pressure of 8 tons. The upset deformation is 30%, and the drawing deformation is 25%, finally obtaining an alloy billet with a diameter of about 25mm.

[0077] like Figure 3 As shown, the three-dimensional coordinate robot 11 feeds an alloy billet with a diameter of about 25mm into the high-temperature spiral roller drawing system 4. At this time, the alloy billet is in a high-temperature state and has a small deformation resistance. Therefore, the drawing speed is set to 25mm / s. The alloy billet with a diameter of 25mm is drawn into an alloy wire with a diameter of 8mm step by step, and then the wire is wound up. The three-dimensional coordinate robot 11 winds it into the high-temperature wire spool 46.

[0078] like Figure 4 As shown, the three-dimensional coordinate robot 11 draws an 8mm diameter alloy wire from the high-temperature wire spool 46 and feeds it into the induction heat treatment device 5 for stress-relieving annealing. The annealing temperature is set to 650℃ and the annealing time is 12min.

[0079] like Figure 5 As shown, an 8mm diameter alloy wire is drawn out from the wire outlet 55 of the induction heat treatment device 5 and fed into the low-temperature spiral roller drawing system 6 for cold drawing. At this time, the alloy wire temperature is low and the deformation resistance is high. Therefore, the drawing speed is set to 5mm / s, and the 8mm diameter alloy wire is drawn into a 2mm diameter alloy wire step by step. The 2mm diameter wire is drawn out from the last second roller drawing unit 61 and wound up into the moving wire spool 66. The moving wire spool 66 can then be removed and immediately put into recycling operations or stored for later use.

It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, other embodiments can also be made, which are all within the protection scope of the present application.

[0081] However, they cannot be understood as a limitation to the protection scope of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, other embodiments can also be made, which are all within the protection scope of the present application.
