Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing of aluminum alloy components, and particularly to a high-quality and high-efficiency forming manufacturing process integrating forging and heat treatment of aluminum alloy components. Background Art

[0002] Aluminum alloys play a crucial role in modern industry and manufacturing, especially in the aerospace field, due to their light weight, high strength, and good processing performance. Among various forming technologies, casting and forging are two main forming methods.

[0003] Casting technology offers many advantages, including reducing the machining process required for the final product and being able to produce components with highly complex geometries. However, due to casting defects such as shrinkage cavities, residues, and porosity, aluminum alloy products produced by traditional casting processes usually have low strength, and their mechanical properties often fail to meet the requirements for constructing high-performance components.

[0004] Forging forming technology is highly regarded because it can produce forgings with a denser internal structure, providing higher mechanical properties. Nevertheless, the deformation resistance in traditional forging processes is relatively large, requiring high equipment requirements, poor metal fluidity filling performance, and a cumbersome production process, low efficiency, high energy consumption, and high costs.

[0005] In summary, although traditional casting processes can produce aluminum alloy products with complex structures, they often encounter defects such as gas shrinkage cavities and inclusions, which seriously affect the strength and mechanical properties of the products. At the same time, although forging forming technology can manufacture forgings with a dense structure and excellent mechanical properties, its production efficiency is low, accompanied by high energy consumption and costs. Summary of the Invention

[0006] In view of this, the present invention proposes a high-quality and high-efficiency forming manufacturing process integrating forging and heat treatment of aluminum alloy components. By adopting the new process of integrating forging and heat treatment, it not only fully utilizes the respective advantages of casting and forging but also cleverly avoids their deficiencies. Through this process, the manufactured parts not only have a dense structure and few defects such as holes but also significantly shorten the forming process flow while meeting the product performance requirements, greatly reducing the production cycle and costs. In the production of aluminum alloy parts, the perfect combination of shape control and property control is achieved.

[0007] The technical solution of the present invention is realized as follows:

[0008] In the first aspect, the present invention provides a high-quality and high-efficiency forming manufacturing process integrating forging and heat treatment of aluminum alloy components, selecting an aluminum alloy blank and forging it at a first preset temperature to obtain an aluminum alloy forging product meeting technical requirements;

[0009] Among them, the first preset temperature makes the aluminum alloy blank in a solid-liquid coexistence state.

[0010] The aluminum alloy blank is heated to a solid-liquid coexistence state, i.e., semi-solid state, within the first preset temperature range. When heating to the solid-liquid coexistence state, the heating temperature and holding time are controlled.

[0011] This process optimizes the process of aluminum alloy forming. By performing forging forming in a solid-liquid coexistence state, for cast-formed components, it significantly improves the problem of coarse structure in the as-cast state, eliminates internal defects such as shrinkage porosity and holes, thereby greatly enhancing the overall performance of the casting. And it can produce highly complex shapes that cannot be effectively achieved by extrusion or machining, and can also produce large and small components as well as components with textured or smooth surfaces such as thin walls. For traditional forging-formed components, because this process forms in a solid-liquid coexistence state, it reduces the stringent requirements for the strength and rigidity of the equipment due to high deformation resistance, improves the fluidity when the metal fills the mold, reduces the non-uniformity and cracking risk during the forging process. After forming, the strength of the component is ensured through short-term aging, simplifying the process flow of the traditional forging process.

[0012] The present invention not only shortens the forming cycle and reduces the cost, but also can manufacture thin-walled and complex products, while ensuring the consistency and reliability of the product quality and performance. Through the process flow, the production of large aluminum alloy components will be more efficient and economical, and at the same time, the product quality will also be significantly improved, meeting the needs of modern industry for high-performance aluminum alloy components.

[0013] On the basis of the above technical solutions, further, when the aluminum alloy blank is 6-series aluminum alloy, the first preset temperature is 550 - 620 °C.

[0014] When the aluminum alloy blank is 7-series aluminum alloy, the first preset temperature is 490 - 520 °C.

[0015] When the first preset temperature is too small, the aluminum alloy blank is in a solid state, and the deformation resistance is large during forging forming, making it difficult to form complex forgings. When the first preset temperature is too large, on the one hand, the aluminum alloy blank will melt, making it difficult to form, and on the other hand, the structure of the forging after forging forming will show dendritic structure, reducing the mechanical properties of the forging.

[0016] On the basis of the above technical solutions, further, the aluminum alloy blank is heated to the first preset temperature, the holding time is the first preset time, and deformation forging is performed at the first preset temperature.

[0017] The traditional forging method is to transfer after heating, and this transfer will cause the temperature to drop. The sudden temperature drop will affect the performance after forming. Forming at the same temperature can avoid this influence.

[0018] On the basis of the above technical solution, further, the relationship between the first preset time and the diameter of the aluminum alloy blank is: T = K·D, where K is a conversion coefficient and D is the diameter of the aluminum alloy blank;

[0019] When the aluminum alloy blank is a 6-series aluminum alloy, K = 1.5 mm / min, and when the aluminum alloy blank is a 7-series aluminum alloy, K = 3 mm / min.

[0020] When the aluminum alloy blank is a 6-series aluminum alloy, K = 1.5 mm / min; when the aluminum alloy blank is a 7-series aluminum alloy, K = 3 mm / min.

[0021] When the diameter of the aluminum alloy blank is fixed, if the holding time is too short, the core part of the aluminum alloy blank will not be heated thoroughly, affecting the mechanical properties of the forging. If the holding time is too long, the gas solubility in the aluminum alloy will increase, and a large amount of gas will precipitate to form pores. In addition, impurities and defects inside the material may further aggregate and expand, reducing the density and mechanical properties of the material, becoming a potential hazard in subsequent use.

[0022] On the basis of the above technical solution, further, it also includes directly quenching the forged aluminum alloy blank.

[0023] On the basis of the above technical solution, further, the quenching time is 15 - 20 s.

[0024] On the basis of the above technical solution, further, it also includes aging the quenched aluminum alloy blank at a second preset temperature for a second preset time.

[0025] The present invention omits the solution heat treatment process after forging, saves the use of a solution furnace, can form a supersaturated solid solution by directly quenching after forging, and at the same time avoids abnormal grain growth; subsequent aging treatment ensures the precipitation of strengthening phases to improve mechanical properties.

[0026] On the basis of the above technical solution, further, when the aluminum alloy blank is a 6-series aluminum alloy, the second preset temperature is 160°C - 180°C, and when the aluminum alloy blank is a 7-series aluminum alloy, the second preset temperature is 100 - 120°C.

[0027] On the basis of the above technical solution, further, when the aluminum alloy blank is a 6-series aluminum alloy, the second preset time is 4 - 8 h, and when the aluminum alloy blank is a 7-series aluminum alloy, the second preset time is 24 - 27 h.

[0028] On the basis of the above technical solution, further, the shape of the forging is any one of a barrel shape and a disc shape.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] (1) The present invention adopts a process flow that combines forging and heat treatment, achieving the integration of the advantages of traditional aluminum alloy casting and forging processes and cleverly avoiding their respective deficiencies. This method not only ensures the shape control and performance requirements of the workpiece, but also the produced workpiece has the characteristics of uniform structure and extremely few defects such as pores.

[0031] (2) On the premise of ensuring the product performance, the present invention significantly simplifies the product forming process flow, greatly shortens the production cycle, effectively reduces the production cost, and realizes the double improvement of efficiency and economy.

[0116] Performance testing:

[0117] Cut tensile specimens from the parts processed in the above examples and comparative examples. According to the GB / T228.1-2010 standard, conduct unidirectional tensile tests to test their mechanical properties after forming. Take the average value of multiple tensile specimens. The tensile strength and yield strength of each example and comparative example are shown in Table 1 below:

[0118] Table 1 Tensile strength and yield strength of each example and comparative example

[0119] Number Aluminum alloy series Tensile strength / MPa Yield strength / MPa Example 1 6082 368 346 Example 2 6082 341 329 Example 3 6082 312 290 Example 4 6082 297 261 Example 5 7075 545 471 Example 6 7075 540 477 Example 7 7075 536 469 Comparative example 1 6082 261 242 Comparative example 2 6082 276 249 Comparative example 3 6082 / / Comparative example 4 7075 / / Comparative example 5 7075 / / Comparative example 6 6082 359 337 Comparative example 7 6082 241 219 Comparative example 8 6082 341 322 Comparative example 9 6082 317 293 Comparative example 10 7075 533 464 Comparative example 11 7075 509 491

[0120] From the test results of the unidirectional tensile tests of the above examples, it can be seen that the tensile strength and yield strength of the aluminum alloy forging products prepared in Example 1 reach 368 MPa and 346 MPa, exceeding the traditional T6 standard; the first preset temperatures of Comparative Example 3 and Comparative Example 5 are too high, and cracking occurs in the aluminum alloy during the forming process. The first preset temperature of Comparative Example 4 is too low, and the deformation resistance of the aluminum alloy is too large, making it difficult to form. The tensile strength and yield strength of the aluminum alloy forging products prepared in Example 5 reach 545 MPa and 471 MPa, exceeding the traditional T6 standard.

[0121] By comparing the results of Example 1 and Comparative Example 1, it can be seen that when deforming on a 150°C die, uneven segregation and precipitation occur during the process of the forging temperature dropping. Coarse precipitates are formed at the grain boundaries after aging, reducing the mechanical properties of the forging.

[0122] By comparing the results of Example 1 and Comparative Example 2, it can be seen that when forming at 450°C, alloying elements magnesium and silicon have not been fully dissolved into the aluminum matrix, the solid solubility is low, and sufficient amounts of highly supersaturated solid solutions cannot be formed. During the subsequent aging process, the number of solute atoms available for precipitation is insufficient, resulting in an insignificant aging strengthening effect and lower tensile strength and yield strength of the alloy.

[0123] By comparing the results of Example 1 and Comparative Example 6, it can be seen that when forging a billet that is not fully heated internally, due to large temperature differences in different parts, the deformation is uneven, resulting in coarse and uneven grains, and reducing the mechanical properties such as tensile strength and yield strength of the final forging.

[0124] By comparing the results of Example 1 and Comparative Example 7, it can be seen that first, when deforming on a 150°C die, uneven segregation and precipitation occur during the process of the forging temperature dropping. Second, holding at 600°C after deformation eliminates the forging structure on the one hand, and on the other hand, the low-melting eutectics at the grain boundaries, trigonal grain boundaries, and inside the grains are locally melted. Ultimately, the mechanical properties of the forging are reduced.

[0125] By comparing the results of Example 1 and Comparative Example 8, it can be seen that traditional forging eliminates the forging structure during the subsequent heat treatment process on the one hand, and on the other hand, abnormal grain growth occurs, resulting in coarse grains and affecting the mechanical properties of the forging.

[0126] By comparing the results of Example 1 and Comparative Example 9, it can be seen that during the forging process, plastic deformation refines grains, eliminates porosity, makes the internal structure dense and uniform, can also form a fiber structure consistent with the stress direction, optimizes the macroscopic structure, reduces segregation, and thus significantly improves the strength, toughness, and comprehensive mechanical properties of the material. Casting, on the other hand, is prone to defects such as porosity, voids, and segregation, resulting in lower mechanical properties.

[0127] By comparing the results of Example 5 and Comparative Example 10, it can be seen that traditional forging eliminates the forging structure during the subsequent heat treatment process on the one hand, and on the other hand, abnormal grain growth occurs, resulting in coarse grains and affecting the mechanical properties of the forging.

[0128] By comparing the results of Example 5 and Comparative Example 11, it can be seen that during the forging process, plastic deformation refines grains, eliminates porosity, makes the internal structure dense and uniform, can also form a fiber structure consistent with the stress direction, optimizes the macroscopic structure, reduces segregation, and thus significantly improves the strength, toughness, and comprehensive mechanical properties of the material. Casting, on the other hand, is prone to defects such as porosity, voids, and segregation, resulting in lower mechanical properties.

[0129] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
