DETAILED DESCRIPTION

[0042] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0044] Example 1 In order to make the technical solution of the embodiment of the present application clearer and easier to understand, the application background of the embodiment of the present application is introduced below.

[0045] Aluminum alloy ring parts are key connectors for launch vehicles and aircraft. They can connect different structural segments or components, such as the connection between the engine and the fuel tank. Due to their characteristics of light weight, high strength, corrosion resistance, high structural strength and good thermal conductivity, the structural performance of aluminum alloy ring parts also affects the performance of launch vehicles and aircraft to a certain extent.

[0046] The production process of ring forgings mainly includes bar casting, sawing, heating, upsetting / punching, rolling, heat treatment, rough turning and ultrasonic flaw detection. The equipment involved in the production process includes semi-continuous casting machines, cutting machines, forging machines, rolling mills, heat treatment furnaces, lathes and ultrasonic flaw detection equipment. As a result, the processing technology of ring forgings has the following problems: (1) Preparation equipment: The production process is complex, the production cycle is long, and the equipment investment is large At present, the production of ring forgings requires multiple complicated processes. It takes several months to produce one ring forging. At the same time, many types of equipment are involved and the equipment capacity requirements are high. The current situation of ring forgings is that supply exceeds demand.

[0047] (2) Preparation process: The ring casting has precise dimensions and small deformation during heat treatment. At present, ring forgings have a certain degree of heat treatment deformation during the solution and quenching process, which seriously affects the dimensional accuracy of the ring parts and has a low yield rate.

[0048] In view of this, the embodiment of the present application is based on the melt impact technology characteristics: high solid solubility, low segregation rate, ultrafine fully equiaxed crystals and no obvious defects, etc., to design 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 links, thereby improving casting efficiency and reducing various production costs. At the same time, in the embodiment of the present application, the solid solution process of the annular casting is carried out in an annular mold, which has a good shape control effect on the annular casting in a solid solution state. At the same time, gas is used as the quenching medium to ensure that the annular casting has the advantages of small deformation and bright surface.

[0049] Specifically, the embodiments of the present application aim at the shortcomings of aerospace ring parts such as long production cycle, complex production process, and large equipment investment, and combine the high solid solubility, low segregation rate, and fully equiaxed crystal characteristics of the melt impact method to propose an aviation aluminum alloy manufacturing device to meet the manufacturing needs of aerospace equipment; please refer to Figure 4 The fourth working state schematic diagram of the aviation aluminum alloy manufacturing device provided by the present embodiment is shown, and the manufacturing device comprises: a melt impact module 1, a heat treatment module 2 and a quenching module 3 that cooperate with each other; The melt impact module 1 has a melt impact chamber 4, and a bearing surface for placing a mold 5 is formed in the melt impact chamber 4; the melt impact chamber 4 is used to obtain a ring part 6 through melt impact processing; The heat treatment module 2 has a heat treatment chamber 7, and the adjacent side walls of the heat treatment chamber 7 and the melt impact chamber 4 are both provided with movable structural plates; when the structural plate moves in a first direction away from the mold 5, the heat treatment chamber 7 is communicated with the melt impact chamber 4, and the mold 5 and the annular member 6 thereon can be moved from the melt impact chamber 4 to the heat treatment chamber 7 for heat treatment; The quenching module 3 has a quenching chamber 8, and a movable quenching sealing plate 9 is arranged between the quenching chamber 8 and the heat treatment chamber 7; when the quenching sealing plate 9 moves along the second direction away from the quenching chamber 8, the heat treatment chamber 7 is connected to the quenching chamber 8, and the heat-treated mold 5 and the annular part 6 thereon 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.

[0050] In the embodiment of the present application, the melt impact chamber 4 of the melt impact module 1 is mainly used to obtain a melt impact ring part of a desired size, and a bearing surface for placing a mold 5 is also formed in the melt impact chamber 4, on which the ring mold 5 and the bottom mold base 24 arranged below the mold 5 can be placed; the heat treatment chamber 7 of the heat treatment module 2 is mainly used to perform high-temperature heat treatment and low-temperature heat treatment on the melt impact ring part, and the high-temperature heat treatment and low-temperature heat treatment here at least include homogenization treatment, solution treatment, low-temperature annealing treatment and aging treatment; the quenching chamber 8 of the quenching module 3 is mainly used to allow the ring part after high-temperature treatment to be cooled quickly, to obtain a casting with a certain solid solubility structure state, and to prepare the structure for subsequent processing, wherein the quenching medium is gas, which has a good shape control effect, so that the ring part has the advantages of small deformation and bright surface.

[0051] In order to shorten the production cycle of the ring parts, simplify the complexity of the production process and reduce the production cost, in the embodiment of the present application, the adjacent side walls of the heat treatment chamber 7 and the melt impact chamber 4 are provided with a movable structural plate, so that when the structural plate moves along the first direction away from the mold 5, the heat treatment chamber 7 can be connected with the melt impact chamber 4, and the mold 5 can be directly moved from the melt impact chamber 4 to the heat treatment chamber 7, where 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, and the quenching chamber 8 can also be connected with the heat treatment chamber 7, so that when the quenching sealing plate 9 is withdrawn, the mold 5 can also be directly moved from the heat treatment chamber 7 to the quenching chamber 8; during the operation of the device, the mold 5 does not need to be frequently moved between multiple devices to perform different process treatments, and multiple process treatments can be completed by moving between the melt impact chamber 4, the heat treatment chamber 7 and the quenching chamber 8.

[0052] In a preferred embodiment, see Figure 3 or Figure 4 , the melt impact module 1 comprises: a first impact unit and a second impact unit; The first impact unit includes: a sealing main frame 10 and a first carrier platform 11 disposed at the bottom of the sealing main frame 10; the first carrier platform 11 can move along a first direction and is in close contact with the sealing main frame 10 to form a first impact chamber 12 together; a side plate of the sealing main frame 10 close to the heat treatment chamber 7 is a first sealing plate 13 that can move along the first direction, and an upper surface of the first carrier platform 11 forms a bearing surface; The second impact unit is arranged at the top of the sealing main frame 10, and has a second impact cavity 14 inside. A high-temperature melt jet part is arranged in the second impact cavity 14. The high-temperature melt jet part has an injection end. The injection end extends into the interior of the sealing main frame 10 and is used to spray the melt to the mold 5 placed in the first impact cavity 12; the first impact cavity 12 and the second impact cavity 14 form a melt impact chamber 4.

[0053] Specifically, the melt impact module 1 includes a first impact unit and a second impact unit, and the two impact units are respectively formed with a first impact cavity 12 and a second impact cavity 14, that is, a melt impact chamber 4; wherein the first impact unit includes: a sealed main frame 10 and a first carrier platform 11 arranged at the bottom of the sealed main frame 10, the sealed main frame 10 is a cover body with an opening at the bottom, and the first carrier platform 11 is a movable platform arranged at the bottom opening of the sealed main frame 10, which can seal the sealed main frame 10 into a space (the space is the first impact cavity 12), and the upper surface of the first carrier platform 11 is the bearing surface of the melt impact module 1, which is used to place the mold 5.

[0054] Here, the movable first carrying platform 11 can be composed of a first driving member 29 and a platform structure; specifically, the first driving member 29 can be a cylinder, which drives the platform structure to move closer to and away from the sealing main frame 10 (see Figure 2 and Figure 3 When the first carrier platform 11 is away from the sealing main frame 10, it can be used to load the mold 5; after the mold 5 is loaded, the first carrier platform 11 moves toward the sealing main frame 10, and is in sealing contact with the sealing main frame 10 to form a sealed first impact cavity 12; see Figure 2 A limiting portion is also provided at the bottom of the sealing main frame 10. When the first carrying platform 11 moves to contact with the limiting portion, it stops moving, and a sealed first impact cavity 12 is formed.

[0055] The second impact unit is a chamber arranged at the top of the sealing main frame 10, that is, a second impact chamber 14 is formed, and a high-temperature melt jet part is arranged in the chamber, which is used to spray the high-temperature melt to the mold 5 in the first impact chamber 12, so that a ring-shaped part 6 obtained by melt impact processing is formed in the mold 5; it should be noted that in order to ensure that the high-temperature melt jet part can accurately spray the high-temperature melt into the annular groove 17 of the mold 5, the high-temperature melt jet part needs to be matched with the groove 17.

[0056] In a preferred embodiment, see Fig.12 The high-temperature melt jet part includes: a crucible, which is used to melt the casting material to obtain a high-temperature melt; A plurality of nozzles 16 are evenly distributed in a ring shape at the bottom of the second impact cavity 14 . The nozzles 16 extend into the interior of the sealing main frame 10 , and their distribution matches the grooves 17 on the mold 5 .

[0057] The high-temperature melt jet part obtains the melted high-temperature melt through the crucible, then opens the upper cover arranged on the top of the second impact unit, places the melted high-temperature melt in the second impact cavity 14, and then fixes and seals the upper cover. Finally, the high-temperature melt can be sprayed toward the mold 5 through a plurality of nozzles 16 arranged at the bottom of the second impact cavity 14. The nozzles 16 here need to extend into the first impact cavity 12 to complete the spraying operation.

[0058] Regarding the arrangement of the nozzles 16 , it is consistent with the aforementioned “the high-temperature melt jet portion needs to be matched with the groove 17 ”. Further, a plurality of annular nozzles 16 may be matched with the groove 17 on the mold 5 .

[0059] In a preferred embodiment, see Figure 4-Figure 6 , Fig.10 , Fig.13 and Fig.14The heat treatment module 2 includes: a heating main frame 18 and a second carrier 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 an active chamber of the second carrier platform 19; The side plate of the heating main frame 18 close to the melt impact chamber 4 and the other side plate opposite to the side plate are both first heating plates 27 that can move along the first direction relative to the stage 20; the inner side wall of the first heating plate 27 is provided with a first limiting portion 21; The second carrying platform 19 is movably disposed in the movable chamber along the first direction. When the second carrying platform 19 moves to the first limiting portion 21 , the second carrying platform 19 and the heating main frame 18 together form a heat treatment chamber 7 .

[0060] The heating main frame 18 is also composed of a sealed main frame 10, which is generally a cover structure, and a loading platform 20 is connected to the bottom thereof to form an active chamber; Figure 1 In the structure shown, the stage 20 includes a groove structure 201, which is connected to the two first heating plates 27 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 a corresponding active chamber and a quenching chamber 8 with the heating main frame 18 and the subsequent quenching sealing plate 9.

[0061] 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 arranged on the top of the heating main frame 18, which is used to uniformly heat the annular part by the first heating plate 27; the structure of the loading platform 20 also includes a loading platform portion extending from the side of the heating main frame 18 away from the melt impact module 1, and the loading platform portion can be used to place the mold 5 that has been subsequently processed from the quenching chamber 8.

[0062] Further, from Figure 5It can also be seen that the first heating plate 27 near one side of 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 stage 20, the first impact chamber 12 is connected with the active chamber; further, the second carrying platform 19 in the active chamber is also used to carry the mold 5, so after the first impact chamber 12 is connected with the active chamber, the mold on the first carrying platform 11 can be moved to the second carrying platform 19, and the second carrying platform 19 can also be composed of a second driving member 30 and a 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, and when the second carrier platform 19 moves to the first limit portion 21, the second carrier 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 are opened synchronously, and the first carrier platform 11 and the second carrier platform 19 are almost flush, so the mold 5 that has completed the melt impact process on the first carrier platform 11 can be quickly moved to the second carrier platform 19 via the connected space and the corresponding guide rail 31, namely, enter the heat treatment chamber 7, and carry out a new process.

[0063] In a preferred embodiment, see Figure 8 A through hole extending along the second direction is also provided on one side wall of the stage 20, and a movable quenching sealing plate 9 is provided in the through hole; The quenching sealing plate 9 extends into the movable chamber along the second direction, and together with the stage 19 forms a quenching chamber 8; here, the second direction is a horizontal direction.

[0064] Furthermore, a quenching sealing plate 9 is provided in the through hole in the side wall of the stage 20. The quenching sealing plate 9 is moved into the active chamber to separate the lower part of the active chamber into a quenching chamber 8. That is, the quenching sealing plate 9 and the groove structure 201 of the stage 20 together constitute the quenching chamber. For details, see Figure 7 to Figure 8 changes in working conditions.

[0065] During the operation of the device, after the annular member 6 is processed in the heat treatment chamber 7, it is necessary to first drive the second carrying platform 19 away from the heating main frame 18 until it moves to the bottom of the movable chamber and contacts the loading platform 20. Then, the quenching sealing plate 9 can be controlled to extend into the movable chamber. At this time, the second carrying platform 19 and the mold 5 thereon enter the quenching chamber 8.

[0066] In a preferred embodiment, see Fig.15 , Fig.16 and Fig.17The quenching module 3 includes: a quenching plate 33, which is arranged in the quenching chamber 8; the quenching plate 33 has a plurality of gas paths 22, and each gas path 22 is provided with a plurality of gas inlets 23 at intervals, and the gas inlets 23 are used to transport quenching gas into the quenching chamber 8.

[0067] Since the quenching medium used in the embodiment of the present application is gas, a plurality of gas paths 22 are arranged inside the quenching plate 33 arranged in the quenching chamber 8, and a plurality of spaced-apart gas inlets 23 are distributed on each gas path 22. In this way, by opening the gas valve 32 on each gas path 22, the gas flowing in the quenching plate 33 can enter the quenching chamber 8.

[0068] Further, see Fig.16 and Fig.17 The quenching plate 33 is connected to the stage 20 and is arranged on two opposite sides (the two quenching plates 33 can be ventilated alternately, which is beneficial to uniform quenching of the workpiece). Then the quenching plate 33, the stage 20 and the quenching sealing plate 9 are jointly sealed into 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 stage 20, which can be adjusted according to actual conditions.

[0069] In a preferred embodiment, see Figure 5 and Fig.10 The mold 5 is provided with a mold base 24 at the bottom, and the mold base 24 has a connecting end 25; the manufacturing device also includes: a hanging driving assembly, the hanging driving assembly includes a driving part and a hanging end 26 connected to the driving part, and the driving part is used to drive the hanging end 26 to move toward the mold base 24 and hang with its connecting end 25; The connection end 25 is connected to the hanging end 26 to drive 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 .

[0070] The manufacturing device also needs to include a component for driving the mold 5 to move, that is, the hanging drive assembly here, which includes a hanging end 26, and the hanging end 26 can be hung with the connecting end 25 on the mold base 24 to complete the connection with the mold 5. When the hanging end 26 is hung with the mold base 24 under the mold 5, after the melt impact chamber 4 and the heat treatment chamber 7 are in a connected state, the mold 5 in the melt impact chamber 4 can be moved to the heat treatment chamber 7 by driving the hanging end 26 to retract; and after the quenching process is completed, the hanging drive assembly can also drive the hanging end 26 to hang with the connecting end 25 on the mold base 24, so as to move the mold 5 and the mold base 24 to the loading platform portion extended from the loading platform 20.

[0071] Here, the hanging drive assembly can be composed of a cylinder, an extension rod and a hook. The hook serves as the hanging end 26 in the hanging drive assembly, the cylinder serves as the driving part in the hanging drive assembly, and the connecting end 25 is an annular connecting part arranged on the mold base 24; the hook is arranged at one end of the extension rod, and the other end of the extension rod is 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 hanging drive assembly is not limited. As long as it is used to drive the mold 5 to move, it can also be directly completed by other components such as a robot.

[0072] Example 2 See also Fig.19 Based on the aviation aluminum alloy manufacturing device of Example 1, the present application embodiment proposes a method for preparing a ring-shaped part, the preparation method comprising: S1, placing the smelted high-temperature melt in the second impact cavity 14, controlling the first carrier platform 11 to carry the mold 5 in close contact with the sealed main frame 10, and at this time the mold 5 is located in the sealed first impact cavity 12; S2, controlling 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 ejected from the second impact chamber 14 into the mold 5, and the melt impacts the annular member 6; S3, control the first heating plate 27 and the first sealing plate 13 to open, and start the hanging driving assembly at the same time, use its hanging end 26 to connect with the connecting end 25 of the mold base 24 below the mold 5, and move the mold 5 from the first impact cavity 12 to the second carrying platform 19 in the heat treatment chamber 7; S4, setting the heat treatment chamber 7 to operate according to the first operating parameters to perform high temperature heat treatment on the melt impact annular casting; S5, control the second carrying platform 19 to move toward the loading platform 20, and start the quenching sealing plate 9 to extend into the movable chamber along the second direction to separate the quenching chamber 8 in the movable chamber, and then quench the melt impact annular casting after high-temperature heat treatment.

[0073] In the embodiment of the present application, the mold 5 and the mold base 24 need to be fixed first, and then the two are placed on the first carrier platform 11, and then the first driving member 29 drives the first carrier platform 11 to move to the limit portion on the sealing main frame 10. At this time, the mold 5 is in the first impact cavity 12, that is, located in the melt impact chamber 4; during the process, the high-temperature melt after smelting needs to be placed in the second impact cavity 14 (see Figure 3 ), the high temperature melt is sprayed into the mold 5 from the nozzle 16 at the bottom of the second impact cavity 14 (see Figure 4 ).

[0074] At this time, the entire first impact chamber 12 and the second impact chamber 14 are in a sealed state, and the gas pressure N2 is introduced into the two chambers to normal pressure to ensure that the entire melt impact environment is in an oxygen-free state; a certain pressure is added to the second impact chamber 14, so that there is a certain pressure difference between the first impact chamber 12 and the second impact chamber 14, so that the high-temperature melt (high-temperature aluminum liquid) is ejected from the nozzle 16, and the high-temperature melt is completely sprayed into the annular mold 5 to obtain a ring part 6 of a certain size. The pressure difference here needs to be selected according to the process, and there is no special limitation. Taking 7085 alloy as an example, the pressure difference can be selected at 30Kpa.

[0075] After obtaining the ring-shaped part 6 of a certain size, the first heating plate 27 and the first sealing plate 13 need to be controlled to open, and at the same time, the hanging drive assembly is started to drive the hanging end 26 to extend and connect with the connecting end 25 of the mold base 24 in the first impact cavity 12, and then the driving part connected to the hanging end 26 controls the hanging end 26 to retract, and moves the mold 5 from the first carrying platform 11 of the first impact cavity 12 to the second carrying platform 19 in the heat treatment chamber 7 to carry out the heat treatment process.

[0076] When entering the heat treatment process, it is necessary to set the operating parameters of the heat treatment chamber 7 according to the process requirements, that is, set the first heating plate 27 in the heat treatment chamber 7 to operate according to the first operating parameters, perform high-temperature heat treatment on the melt impact annular casting, and start the stirring fan 28 at the same time; It should be explained that the first operating parameter needs to be set according to the process. For example, the 7085 alloy is an alloy containing Zr elements. For a heat-treatable and hardened deformable aluminum alloy with certain strength requirements, its process parameters are as follows: Fig.18 The curve shown is used for the heat treatment; wherein, the high temperature heat treatment in the 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, wherein 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°C, t1=5H, T2=465°C, t2=8H, T3=475°C, t3=24H for each level of high temperature heat treatment stage; after the high temperature heat treatment, the second driving member 30 is required to control the second carrier platform 19 to move toward the direction close to the stage 20, and start the quenching sealing plate 9 to extend into the active chamber along the second direction to separate the quenching chamber 8 in the active chamber, and then control the quenching plate 33 to quench the melt impact annular casting after the high temperature heat treatment.

[0077] During the quenching process, it is necessary to open the gas valve 32 to allow the gas to enter the quenching chamber 8 through the air inlet 23 on the quenching plate 33. The gas pressure can be set to 0~10Bar, and the quenching frequency can be set to 0~30s (that is, the air intake frequency of the two quenching plates 33 is alternately ventilated, which is conducive to uniform quenching of the workpiece), but the specific parameters are not specifically limited.

[0078] In a preferred embodiment, see Figure 8 to Figure 9 The working condition change process, after step S5, quenching the melt impact annular casting after high temperature heat treatment, also includes: S6, controlling the quenching sealing plate 9 to move away from the active chamber along the second direction, and controlling the second carrying platform 19 to move to the first limiting portion 21 in the direction close to the heating main frame 18, so as to drive the mold 5 to return to the heat treatment chamber 7; S7, setting the heat treatment chamber 7 to operate according to the second operating parameters, and performing peak aging treatment on the melt impact annular casting after quenching treatment.

[0079] After the quenching treatment, the cylinder controlling the quenching sealing plate 9 is started to restore the quenching sealing plate 9 to its original position (not extending into the active chamber), and then the second driving member 30 of the second carrying platform 19 is controlled to drive the mold 5 to rise to the first limit portion 21. At this time, the annular member 6 is moved to the heat treatment chamber 7 for cooling. Here, it is necessary to set the heat treatment chamber 7 to operate according to the second operating parameters again, and at the same time start the stirring fan 28 to perform peak aging treatment on the annular member 6, that is, perform low-temperature heat treatment on the annular member 6. The specific treatment parameters can also be seen in Fig.18 , where T T 1 = 121 °C, t t 1=24H.

[0080] It should be explained that when the ring 6 is subjected to high temperature treatment, quenching treatment and subsequent peak aging treatment, different heat treatment systems are used for different aluminum alloys and process requirements. In other words, the settings of the first operating parameter, the quenching treatment parameter and the second operating parameter need to be adjusted according to the actual process parameters. In addition to the above-mentioned process parameter settings for the heat-treatable strengthened deformable aluminum alloy containing Zr elements with certain strength requirements, the following situations are also specifically included: (1) For non-heat-treatable strengthened deformed aluminum alloys that do not contain Zr, high-temperature heat treatment is mainly used to eliminate non-equilibrium solidification phases, and low-temperature heat treatment is mainly used for stabilization treatment; the quenching pressure P can be 0~1.5Bar, and the quenching frequency H can be 0~30s / time. The specific process parameters are as follows: Fig. 20 The curve shown is carried out.

[0081] (2) For non-heat-treatable strengthened deformed 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 Al3Zr dispersed phase; the second-stage high-temperature heat treatment is mainly used to eliminate the low-melting point eutectic phase, and the low-temperature heat treatment is mainly used for stabilization treatment; the quenching pressure P can be 0~1.5Bar, the quenching frequency H can be 15~30s / time, and the specific process parameters are as follows: Fig.21 The curve shown is carried out.

[0082] (3) For heat-treatable and deformable aluminum alloys that do not contain Zr and have certain strength requirements, the first stage of high-temperature heat treatment is mainly used to eliminate the low-melting point non-equilibrium eutectic phase; the second stage of high-temperature heat treatment is mainly used to eliminate the high-melting point phase, and the peak aging treatment is mainly used to obtain a finely dispersed strengthening phase; the quenching pressure P can be 2~10Bar, and the quenching frequency H can be 5~15s / time. The specific process parameters are as follows: Fig. 22 The curve shown is carried out.

[0083] (4) For heat-treatable and strengthened deformable aluminum alloys that do not contain Zr and have certain corrosion resistance requirements, the first stage of high-temperature heat treatment in the high-temperature treatment is mainly used to eliminate the low-melting point non-equilibrium eutectic phase; the second stage of high-temperature heat treatment is mainly used to eliminate the high-melting point phase; the peak aging treatment can be divided into the first stage aging treatment and the second stage aging treatment; among them, the main purpose of the first stage aging treatment is to obtain the precursor, and the purpose of the second stage aging treatment is to obtain a strengthening phase with a certain distribution structure (to improve corrosion resistance); the quenching pressure P can be 2~10Bar, the quenching frequency H can be 5~15s / time, and the specific process parameters are as follows: Fig.23 The curve shown is carried out.

[0084] (5) For heat-treatable and strengthened deformable aluminum alloys containing Zr elements with certain corrosion resistance requirements, the first stage of high-temperature heat treatment is mainly used to precipitate Al3Zr dispersed phase, the second stage of high-temperature heat treatment is mainly used to eliminate low-melting point non-equilibrium eutectic phase, and the third stage of high-temperature heat treatment is mainly used to eliminate high-melting point phase; the main purpose of the first stage of aging treatment is to obtain precursors, and the purpose of the second stage of aging treatment is to obtain a strengthening phase with a certain distribution structure (to improve corrosion resistance); the quenching pressure P is 2~10Bar, the quenching frequency H is 5~15s / time, and the specific process parameters are as follows: Fig.24 The curve shown is carried out.

[0085] In a preferred embodiment, see Figure 9-11 The working condition change process, after step S7, performing peak aging treatment on the melt impact ring casting after quenching treatment, also includes: S8, control the first heating plate 27 away from the side of the melt impact chamber 4 to open, start the hanging drive assembly, use its hanging end 26 to connect with the connecting end 25 of the mold base 24 below the mold 5, and move the mold 5 from the second carrying platform 19 to the loading platform 20 located outside the heat treatment module 2.

[0086] After the peak aging treatment, the first heating plate 27 on the side away from the melt impact chamber 4 is controlled to open, so that the hanging end 26 can be controlled to be connected with the connecting end 25, so as to drive the mold 5 to be moved from the second carrying platform 19 to the loading platform part of the loading platform 20, and 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.
