[0002] Aluminum alloy ring components are key connecting parts for launch vehicles and aircraft, connecting different structural sections or components, such as the connection between the engine and the fuel tank. Due to their lightweight, high strength, corrosion resistance, high structural strength and good thermal conductivity, the structural performance of aluminum alloy ring components also affects the performance of launch vehicles and aircraft to a certain extent.

[0062] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0063] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0064] Example 1

[0065] To make the technical solutions of the embodiments of this application clearer and easier to understand, the application background of the embodiments of this application is introduced below.

[0066] Aluminum alloy ring components are key connecting parts for launch vehicles and aircraft, connecting different structural sections or components, such as the connection between the engine and the fuel tank. Due to their characteristics of being lightweight and high-strength, corrosion-resistant, structurally strong, and having good thermal conductivity, the structural performance of aluminum alloy ring components also affects the performance of launch vehicles and aircraft to a certain extent.

[0067] The production process of ring forgings mainly includes bar casting, sawing, heating, upsetting / punching, rolling, heat treatment, rough turning, and ultrasonic testing. The equipment involved in the production process includes semi-continuous casting machines, cutting machines, forging machines, rolling mills, heat treatment furnaces, lathes, and ultrasonic testing instruments. Therefore, the processing technology of ring forgings presents the following problems:

[0068] (1) Preparation equipment: The production process is complex, the production cycle is long, and the equipment investment is large.

[0069] Currently, the production of ring forgings requires many complex processes, and it takes several months to produce one ring forging. At the same time, it involves a variety of equipment with high capacity requirements, and the current situation is that the supply of ring forgings cannot meet the demand.

[0070] (2) In terms of manufacturing process: the ring casting has precise dimensions and small deformation during heat treatment.

[0071] Currently, ring forgings exhibit a certain degree of heat treatment deformation during solution treatment and quenching, which severely affects the dimensional accuracy of the ring forgings and results in a low yield.

[0072] In view of this, this application embodiment, based on the advantages of melt impact casting technology such as high solid solubility, low segregation rate, ultra-fine equiaxed crystals, and no obvious defects, designs an integrated production equipment that can perform the process of melt impact casting ring parts - heat treatment - rough turning - ultrasonic flaw detection, eliminating many intermediate preparation steps, thereby improving casting efficiency and reducing various production costs. At the same time, in this application embodiment, the solution treatment process of the ring casting is carried out in the ring mold, which has a good shape control effect on the ring casting in the solution state. Meanwhile, gas is used as the quenching medium to ensure that the ring casting has the advantages of small deformation and bright surface.

[0073] Specifically, this application addresses the drawbacks of long production cycles, complex processes, and high equipment investment in aerospace ring components. It proposes a manufacturing apparatus for aerospace aluminum alloys, leveraging the high solid solubility, low segregation rate, and equiaxed crystal characteristics of the melt impact method, to meet the manufacturing requirements of aerospace equipment. Please refer to... Figure 4 The schematic diagram shown in this embodiment illustrates the fourth working condition of the aerospace aluminum alloy manufacturing apparatus. The manufacturing apparatus includes: a melt impact module 1, a heat treatment module 2, and a quenching module 3 that cooperate with each other.

[0074] The melt impact module 1 has a melt impact chamber 4, and a bearing surface for placing the mold 5 is formed inside the melt impact chamber 4; the melt impact chamber 4 is used to obtain the ring part 6 by melt impact processing;

[0075] The heat treatment module 2 has a heat treatment chamber 7. The adjacent side walls of the heat treatment chamber 7 and the melt impact chamber 4 are provided with movable structural plates. When the structural plates move away from the mold 5 along the first direction, the heat treatment chamber 7 is connected to the melt impact chamber 4, and the mold 5 and the annular part 6 on it can be moved from the melt impact chamber 4 to the heat treatment chamber 7 for heat treatment.

[0076] The quenching module 3 has a quenching chamber 8, and a movable quenching sealing plate 9 is provided between the quenching chamber 8 and the heat treatment chamber 7. When the quenching sealing plate 9 moves away from the quenching chamber 8 along the second direction, the heat treatment chamber 7 and the quenching chamber 8 are connected, and the heat-treated mold 5 and its annular part 6 can be moved from the heat treatment chamber 7 to the quenching chamber 8 for quenching processing. The second direction is perpendicular to the first direction.

[0077] In this embodiment, the melt impact module 1 has a melt impact chamber 4, the main purpose of which is to obtain a melt impact ring of the required size. A bearing surface for placing a mold 5 is also formed within the melt impact chamber 4. The ring mold 5 and a bottom mold base 24 located below the mold 5 can be placed on this bearing surface. The heat treatment module 2 has a heat treatment chamber 7, which is mainly used for high-temperature and low-temperature heat treatment of the melt impact ring. These high-temperature and low-temperature heat treatments include at least homogenization, solution treatment, low-temperature annealing, and aging treatment. The quenching module 3 has a quenching chamber 8, the main purpose of which is to allow the ring after high-temperature treatment to cool rapidly, obtaining a casting with a certain solid solution structure, preparing the structure for subsequent processing. The quenching medium is gas, which has a good shape control effect, resulting in a ring with small deformation and a bright surface.

[0078] To shorten the production cycle of ring-shaped parts, simplify the complexity of production processes, and reduce production costs, in this embodiment, the adjacent sidewalls of the heat treatment chamber 7 and the melt impact chamber 4 are provided with movable structural plates. This allows the heat treatment chamber 7 to communicate with the melt impact chamber 4 when the structural plates move away from the mold 5 along a first direction. The mold 5 can then move directly from the melt impact chamber 4 to the heat treatment chamber 7. Here, the first direction is the vertical direction. Similarly, a movable quenching sealing plate 9 is provided between the quenching chamber 8 and the heat treatment chamber 7, which also enables communication between the quenching chamber 8 and the heat treatment chamber 7. In this way, when the quenching sealing plate 9 is removed, the mold 5 can also move directly from the heat treatment chamber 7 to the quenching chamber 8. During the operation of this device, the mold 5 does not need to move frequently between multiple devices to perform different processes. Multiple processes can be completed by moving between the melt impact chamber 4, the heat treatment chamber 7, and the quenching chamber 8.

[0079] In a preferred embodiment, see Figure 3 or Figure 4 The melt impact module 1 includes: a first impact unit and a second impact unit;

[0080] The first impact unit includes: a sealed main frame 10 and a first transport platform 11 disposed at the bottom of the sealed main frame 10; the first transport platform 11 can move along a first direction and is in close contact with the sealed main frame 10 to jointly form a first impact cavity 12; the side plate of the sealed main frame 10 near the heat treatment chamber 7 is a first sealing plate 13 that can move along the first direction, and the upper surface of the first transport platform 11 forms a bearing surface;

[0081] The second impact unit is located on the top of the sealed main frame 10 and has a second impact chamber 14 inside. The second impact chamber 14 is provided with a high-temperature melt jet section with a spray end that extends into the sealed main frame 10 for spraying melt onto the mold 5 placed in the first impact chamber 12. The first impact chamber 12 and the second impact chamber 14 form a melt impact chamber 4.

[0082] Specifically, the melt impact module 1 includes a first impact unit and a second impact unit. The two impact units respectively form a first impact cavity 12 and a second impact cavity 14, which are melt impact chambers 4. The first impact unit includes a sealed main frame 10 and a first transport platform 11 disposed at the bottom of the sealed main frame 10. The sealed main frame 10 is a cover with an opening at the bottom, while the first transport platform 11 is a movable platform disposed at the bottom opening of the sealed main frame 10 that can seal the sealed main frame 10 into a space (which is the first impact cavity 12). The upper surface of the first transport platform 11 is the bearing surface of the melt impact module 1, which is used to place the mold 5.

[0083] Here, the movable first transport platform 11 can be composed of a first drive component 29 and a platform structure; specifically, the first drive component 29 can be a cylinder, thereby driving the platform structure to move closer to and away from the sealed main frame 10 (see [reference]). Figure 2 and Figure 3 (Comparison of working conditions); when the first transport platform 11 is away from the sealed main frame 10, it can be used to load the mold 5; after the mold 5 is loaded, the first transport platform 11 moves towards the sealed main frame 10 and makes sealing contact with the sealed main frame 10 to form a sealed first impact cavity 12; see Figure 2 A limiting part is also provided at the bottom of the sealed main frame 10. When the first transport platform 11 moves to contact the limiting part, it can stop moving, and the sealed first impact cavity 12 is thus formed.

[0084] The second impact unit is a chamber located at the top of the sealed main frame 10, forming a second impact chamber 14. A high-temperature melt jet section is provided in this chamber for spraying high-temperature melt into the mold 5 in the first impact chamber 12, so that an annular part 6 is formed in the mold 5 through melt impact processing. It should be noted that in order to ensure that the high-temperature melt jet section can accurately spray the high-temperature melt into the annular groove 17 of the mold 5, the high-temperature melt jet section needs to be matched with the groove 17.

[0085] In a preferred embodiment, see Figure 12 The high-temperature melt jet section includes: a crucible, which is used to melt casting materials to obtain a high-temperature melt;

[0086] The bottom of the second impact chamber 14 has several nozzles 16 evenly distributed in a ring. The nozzles 16 extend into the interior of the sealing main frame 10, and their distribution matches the grooves 17 on the mold 5.

[0087] The high-temperature melt jet section obtains the smelted high-temperature melt through the crucible, then opens the top cover set on the top of the second impact unit, places the smelted high-temperature melt into the second impact chamber 14, and then fixes and seals the top cover. Finally, the high-temperature melt can be sprayed into the mold 5 through several nozzles 16 set at the bottom of the second impact chamber 14. Here, the nozzles 16 need to extend into the first impact chamber 12 to complete the spraying operation.

[0088] Regarding the arrangement of the nozzles 16, it is consistent with the aforementioned "the high-temperature melt jet section needs to be matched with the mold groove 17". Further, it is simply a matter of matching the multiple circumferentially arranged nozzles 16 with the mold groove 17 on the mold 5.

[0089] In a preferred embodiment, see Figures 4-6 , Figure 10 , Figure 13 and Figure 14 The heat treatment module 2 includes a heating main frame 18 and a second transport platform 19; the quenching module 3 includes a loading platform 20 connected to the bottom of the heating main frame 18, and the two together constitute the active chamber of the second transport platform 19.

[0090] The side plate of the heating main frame 18 near the melt impact chamber 4 and the other side plate opposite to the side plate are both first heating plates 27 that can move relative to the platform 20 in the first direction; the inner wall of the first heating plate 27 is provided with a first limiting part 21.

[0091] The second transport platform 19 is movable in the movable cavity along the first direction. When the second transport platform 19 moves to the first limiting part 21, the second transport platform 19 and the heating main frame 18 together form the heat treatment chamber 7.

[0092] The heating main frame 18 is also sealed. The main frame 10 is generally a cover structure, and its bottom is connected to a platform 20, forming a movable chamber; such as Figure 1 The structure shown includes a groove structure 201 in the stage 20, which is connected to two first heating plates 27 that are movably arranged in the heating main frame 18, and is also movably connected to the first sealing plate 13 in the melt impact module 1. The stage 20 not only provides support for the various components in the melt impact module 1, the heat treatment module 2 and the quenching module 3, but also forms corresponding movable chambers and quenching chambers 8 with the heating main frame 18 and the subsequent quenching sealing plate 9.

[0093] It should be explained that the first heating plate 27 is used to heat the mold 5 in the heat treatment chamber 7; in addition, a stirring fan 28 is provided on the top of the heating main frame 18 to uniformly heat the annular part by the first heating plate 27; the structure of the platform 20 also includes a platform section extending from the side of the heating main frame 18 away from the melt impact module 1, which can be used to place the mold 5 after it has been processed from the quenching chamber 8.

[0094] Furthermore, from Figure 5 It can also be seen that the first heating plate 27 near the melt impact module 1 is correspondingly arranged with the first sealing plate 13. In this way, when the first heating plate 27 and the first sealing plate 13 move synchronously in the vertical direction away from the platform 20, the first impact cavity 12 and the movable cavity are connected. Furthermore, the second transport platform 19 in the movable cavity is also used to carry the mold 5. Therefore, after the first impact cavity 12 and the movable cavity are connected, the mold on the first transport platform 11 can be moved to the second transport platform 19. The second transport platform 19 can also be composed of the second driving member 30 and the platform structure. Specifically, the second driving member 30... 0 can be a cylinder, which drives the platform structure to approach and move away from the heating main frame 18. When the second transport platform 19 moves to the first limiting part 21, the second transport platform 19 seals the heating main frame 18 into a space, namely the heat treatment chamber 7. At this time, the corresponding first heating plate 27 and the first sealing plate 13 open synchronously. The first transport platform 11 and the second transport platform 19 are almost flush. Therefore, the mold 5 that has completed the melt impact process on the first transport platform 11 can quickly move to the second transport platform 19 through the connected space and the corresponding guide rail 31, that is, enter the heat treatment chamber 7 for a new process.

[0095] In a preferred embodiment, see Figure 8 The platform 20 also has a through hole extending in the second direction on one side wall, and a movable quenching sealing plate 9 is installed in the through hole.

[0096] The quenching sealing plate 9 extends into the movable cavity along the second direction, forming the quenching chamber 8 together with the stage 19; here, the second direction is the horizontal direction.

[0097] Furthermore, a quenching sealing plate 9 is provided in the through hole in the side wall of the platform 20. The quenching sealing plate 9 moves into the movable chamber, dividing the lower part of the movable chamber into a quenching chamber 8. That is, the quenching sealing plate 9 and the groove structure 201 of the platform 20 together constitute the quenching chamber. For details, please refer to [link to relevant documentation]. Figures 7 to 8 Changes in operating conditions.

[0098] During the operation of the device, after the annular part 6 is processed in the heat treatment chamber 7, the second transport platform 19 needs to be driven away from the heating main frame 18 until it moves to the bottom of the movable chamber and contacts the platform 20. Then, the quenching sealing plate 9 can be controlled to extend into the movable chamber. At this time, the second transport platform 19 and the mold 5 on it enter the quenching chamber 8.

[0099] In a preferred embodiment, see Figure 15 , Figure 16 and Figure 17 The quenching module 3 includes a quenching plate 33, which is disposed in the quenching chamber 8. The quenching plate 33 has multiple air passages 22, and each air passage 22 is provided with multiple air inlets 23 spaced apart. The air inlets 23 are used to deliver quenching gas into the quenching chamber 8.

[0100] Since the quenching medium used in this embodiment is gas, the quenching plate 33 set in the quenching chamber 8 will have multiple air passages 22 inside, and each air passage 22 will have multiple air inlets 23 spaced apart. In this way, by opening the gas valve 32 on each air passage 22, the gas flowing in the quenching plate 33 can enter the quenching chamber 8.

[0101] Further, see Figure 16 and Figure 17 The quenching plate 33 is connected to the platform 20 and is set on opposite sides (the two quenching plates 33 can alternately ventilate, which is conducive to uniform quenching of the workpiece). Then the quenching plate 33, the platform 20 and the quenching sealing plate 9 are sealed together to form a quenching chamber 8. Of course, the quenching plate 33 can also be installed in the side wall of the groove structure 201 of the platform 20. The specific adjustment can be made according to the actual situation.

[0102] In a preferred embodiment, see Figure 5 and Figure 10The bottom of the mold 5 is provided with a mold base 24, and the mold base 24 has a connecting end 25; the manufacturing device also includes: a hook-up drive assembly, which includes a drive part and a hook-up end 26 that is pulsatorically connected to the drive part. The drive part is used to drive the hook-up end 26 to move toward the mold base 24 and hook it with its connecting end 25.

[0103] The connecting end 25 is connected to the hanging end 26 to enable the mold 5 on the mold base 24 to move between the melt impact module 1, the heat treatment module 2 and the quenching module 3.

[0104] The manufacturing apparatus also needs to include a component that moves the mold 5, namely the hook-and-drive assembly. The hook-and-drive assembly includes a hook-and-drive end 26, which can be hooked to the connecting end 25 on the mold base 24 to complete the connection with the mold 5. When the hook-and-drive end 26 is hooked to the mold base 24 under the mold 5, and the melt impact chamber 4 and the heat treatment chamber 7 are in communication, the mold 5 in the melt impact chamber 4 can be moved to the heat treatment chamber 7 by driving the hook-and-drive end 26 to retract. After the quenching process is completed, the hook-and-drive assembly can also move the mold 5 and the mold base 24 to the loading platform portion extended from the loading stage 20 by driving the hook-and-drive end 26 to hook to the connecting end 25 on the mold base 24.

[0105] Here, the hook-and-drive assembly can consist of a cylinder, an extension rod, and a hook. The hook serves as the hook-and-drive end 26, the cylinder serves as the drive unit, and the connecting end 25 is an annular connecting part set on the mold base 24. The hook is set at one end of the extension rod, and the other end of the extension rod can be connected to the cylinder. The hook can be connected to the connecting end under the thrust of the cylinder. Of course, the form of the hook-and-drive assembly is not limited. As long as it is used to drive the mold 5 to move, it can also be accomplished by other components such as a robotic arm.

[0106] Example 2

[0107] See Figure 19 Based on the aerospace aluminum alloy manufacturing apparatus of Example 1, this application proposes a method for preparing a ring-shaped component, the method comprising:

[0108] S1. Place the smelted high-temperature melt into the second impact chamber 14, and control the first transport platform 11 to carry the mold 5 in close contact with the sealed main frame 10. At this time, the mold 5 is located in the sealed first impact chamber 12.

[0109] S2. Control the second impact chamber 14 and the first impact chamber 12 to be within a preset pressure difference range so that the high temperature melt is sprayed from the second impact chamber 14 into the mold 5 to obtain the melt impact ring 6.

[0110] S3. Control the opening of the first heating plate 27 and the first sealing plate 13, and simultaneously start the hook drive assembly. Use its hook end 26 to connect with the connection end 25 of the mold base 24 below the mold 5 to move the mold 5 from the first impact chamber 12 to the second transport platform 19 in the heat treatment chamber 7.

[0111] S4. Set the heat treatment chamber 7 to operate according to the first operating parameters to perform high-temperature heat treatment on the molten impact ring casting.

[0112] S5. Control the second transport platform 19 to move towards the platform 20, and start the quenching sealing plate 9 to extend into the movable chamber along the second direction, so as to separate the quenching chamber 8 in the movable chamber, and then quench the molten impact ring casting after high temperature heat treatment.

[0113] In this embodiment, the mold 5 and mold base 24 are first fixed, and then placed on the first transport platform 11. Subsequently, the first drive member 29 drives the first transport platform 11 to the limiting part on the sealed main frame 10. At this time, the mold 5 is in the first impact chamber 12, that is, in the melt impact chamber 4. During the process, the high-temperature melt after smelting is also placed in the second impact chamber 14 (see...). Figure 3 High-temperature melt is injected into the mold 5 through the nozzle 16 at the bottom of the second impact chamber 14 (see...). Figure 4 ).

[0114] At this time, the entire first impact chamber 12 and the second impact chamber 14 are in a sealed state. Gas pressure N2 is introduced into the two chambers to atmospheric pressure to ensure that the entire molten impact environment is oxygen-free. A certain pressure is added to the second impact chamber 14 to create a certain pressure difference between the first impact chamber 12 and the second impact chamber 14, so that the high-temperature molten material (high-temperature aluminum liquid) is ejected from the nozzle 16 and sprayed into the annular mold 5 to obtain an annular part 6 of a certain size. The pressure difference here needs to be selected according to the process and is not specifically limited. For example, for 7085 alloy, the pressure difference can be selected at 30 kPa.

[0115] After obtaining the annular part 6 of a certain size, the first heating plate 27 and the first sealing plate 13 need to be opened. At the same time, the hanging drive assembly is started, driving the hanging end 26 to extend and connect with the connecting end 25 of the mold base 24 in the first impact chamber 12. Then, the driving part connected to the hanging end 26 controls the hanging end 26 to retract, moving the mold 5 from the first transport platform 11 of the first impact chamber 12 to the second transport platform 19 in the heat treatment chamber 7 for heat treatment.

[0116] When entering the heat treatment process, the operating parameters of the heat treatment chamber 7 need to be set according to the process requirements. That is, the first heating plate 27 in the heat treatment chamber 7 is set to operate according to the first operating parameters to perform high-temperature heat treatment on the ring casting impacted by the melt, and the stirring fan 28 is started at the same time.

[0117] It should be explained that the first operating parameter needs to be set according to the process. For example, 7085 alloy is an alloy containing Zr. For heat-treatable wrought aluminum alloys with certain strength requirements, its process parameters should be set as follows: Figure 18 The curve shown is used for the process; the high-temperature heat treatment in this heat treatment system includes a first-stage high-temperature heat treatment, a second-stage high-temperature heat treatment, and a third-stage high-temperature heat treatment. The first-stage high-temperature heat treatment is mainly used to precipitate the Al3Zr dispersed phase, the second-stage high-temperature heat treatment is mainly used to eliminate the low-melting-point non-equilibrium eutectic phase, and the third-stage high-temperature heat treatment is mainly used to eliminate the high-melting-point phase. Specifically, the first operating parameters here can be set to T1=418℃, t1=5H, T2=465℃, t2=8H, T3=475℃, t3=24H for each stage of high-temperature heat treatment. After the high-temperature heat treatment, the second driving component 30 is used to control the second transport platform 19 to move towards the platform 20, and the quenching sealing plate 9 is activated to extend into the movable chamber along the second direction to separate the quenching chamber 8 in the movable chamber, and then the quenching plate 33 is controlled to impact the ring casting after high-temperature heat treatment for quenching treatment.

[0118] During the quenching process, the gas valve 32 needs to be opened so that the gas enters the quenching chamber 8 through the air inlet 23 on the quenching plate 33. The gas pressure can be set to 0~10 Bar and the quenching frequency to 0~30s (that is, the air inlet frequency of the two quenching plates 33, which alternates the air supply to facilitate uniform quenching of the workpiece), but the specific parameters are not specifically limited.

[0119] In a preferred embodiment, see Figures 8 to 9 The process of changing working conditions, after step S5, quenching the high-temperature heat-treated molten impact ring casting, also includes:

[0120] S6. Control the quenching sealing plate 9 to move away from the active chamber in the second direction, and at the same time control the second transport platform 19 to move towards the heating main frame 18 to the first limit part 21, so as to drive the mold 5 back to the heat treatment chamber 7.

[0121] S7. Set the heat treatment chamber 7 to operate according to the second operating parameters, and perform peak aging treatment on the quenched melt impact ring casting.

[0122] After quenching, the cylinder controlling the quenching sealing plate 9 is activated to restore the quenching sealing plate 9 to its original position (not extended into the movable chamber). Then, the second drive component 30 of the second transport platform 19 is controlled to raise the mold 5 to the first limit part 21. At this time, the annular part 6 is moved into the heat treatment chamber 7 for cooling. Here, the heat treatment chamber 7 needs to be set to operate according to the second operating parameters again. Simultaneously, the stirring fan 28 is activated to perform peak aging treatment on the annular part 6, which is a low-temperature heat treatment of the annular part 6. Specific treatment parameters can be found in [reference needed]. Figure 18 , among which, T T 1 = 121℃, t t 1 = 24H.

[0123] It should be explained that when performing high-temperature treatment, quenching treatment, and subsequent peak aging treatment on the ring-shaped part 6, different heat treatment regimes are required for different aluminum alloys and process requirements. In other words, the settings of the first operating parameter, quenching treatment parameter, and second operating parameter need to be adjusted according to the actual process parameters. In addition to the above-mentioned process parameter settings for heat-treatable and deformable aluminum alloys containing Zr with certain strength requirements, the following situations are also included:

[0124] (1) For non-heat-treatable strengthened wrought aluminum alloys without Zr, high-temperature heat treatment is mainly used to eliminate non-equilibrium solidified phases, and low-temperature heat treatment is mainly used for stabilization. The quenching pressure P can be 0~1.5 Bar, and the quenching frequency H can be 0~30 s / time. The specific process parameters are as follows: Figure 20 The curve shown is used.

[0125] (2) For non-heat-treatable strengthened wrought aluminum alloys containing Zr, high-temperature heat treatment can be divided into first-stage high-temperature treatment and second-stage high-temperature treatment; among them, the first-stage high-temperature heat treatment is mainly used to precipitate the Al3Zr dispersed phase; the second-stage high-temperature heat treatment is mainly used to eliminate the low-melting-point eutectic phase, while the low-temperature heat treatment is mainly used for stabilization treatment; and the quenching pressure P can be 0~1.5 Bar, the quenching frequency H can be 15~30 s / time, and the specific process parameters are as follows: Figure 21 The curve shown is used.

[0126] (3) For heat-treatable deformable aluminum alloys with certain strength requirements that do not contain Zr, the first stage of high-temperature heat treatment is mainly used to eliminate low-melting-point non-equilibrium eutectic phases; the second stage of high-temperature heat treatment is mainly used to eliminate high-melting-point phases; and the peak aging treatment is mainly used to obtain finely dispersed strengthening phases. The quenching pressure P can be 2~10 Bar, and the quenching frequency H can be 5~15 s / time. The specific process parameters are as follows: Figure 22 The curve shown is used.

[0127] (4) For heat-treatable wrought aluminum alloys that do not contain Zr and have certain corrosion resistance requirements, the first stage of high-temperature heat treatment is mainly used to eliminate low-melting-point non-equilibrium eutectic phases; the second stage of high-temperature heat treatment is mainly used to eliminate high-melting-point phases; peak aging treatment can be divided into first-stage aging treatment and second-stage aging treatment; the main purpose of the first-stage aging treatment is to obtain precursors, and the purpose of the second-stage aging treatment is to obtain strengthening phases with a certain distribution structure (to improve corrosion resistance); the quenching pressure P can be 2~10 Bar, the quenching frequency H can be 5~15 s / time, and the specific process parameters are as follows: Figure 23 The curve shown is used.

[0128] (5) For heat-treatable wrought aluminum alloys containing Zr and requiring certain corrosion resistance, the first stage of high-temperature heat treatment is mainly used to precipitate the Al3Zr dispersed phase, the second stage is mainly used to eliminate the low-melting-point non-equilibrium eutectic phase, and the third stage is mainly used to eliminate the high-melting-point phase; the first stage of aging treatment is mainly used to obtain the precursor, and the second stage of aging treatment is used to obtain the strengthening phase with a certain distribution structure (to improve corrosion resistance); the quenching pressure P is 2~10 Bar, the quenching frequency H is 5~15 s / time, and the specific process parameters are as follows: Figure 24 The curve shown is used.

[0129] In a preferred embodiment, see Figures 9-11 The process of changing working conditions, after step S7, which involves peak aging treatment of the quenched melt impact ring casting, also includes:

[0130] S8. Control the opening of the first heating plate 27 on the side away from the melt impact chamber 4, start the hook drive assembly, and use its hook end 26 to connect with the connection end 25 of the mold base 24 below the mold 5 to move the mold 5 from the second transport platform 19 to the platform 20 located outside the heat treatment module 2.

[0131] After peak aging treatment, the first heating plate 27 on the side away from the melt impact chamber 4 is opened to connect the hanging end 26 and the connecting end 25, which moves the mold 5 from the second transport platform 19 to the loading platform of the loading platform 20. Then the ring part 6 on the mold 5 can be taken out to obtain the final 7050 ring part, which can be directly installed and used.
