[0001] The present application relates to the technical field of additive manufacturing of high-temperature alloys, and more specifically, to a surface quality control device and method for additive manufacturing of high-temperature alloy components. Background Art

[0002] The curved busbar components are a type of parts with a wide range of applications, such as the cone-cylinder composite curved busbar components for the combustion chamber casing of an aircraft engine. However, due to the characteristics of their complex shape, this type of parts is difficult to process and is restricted in actual production. The curved busbar components are manufactured using GH4099 alloy for additive manufacturing, and the surface accuracy of the structural parts is high. The existing technology has defects such as shrinkage, inclusions, and cold shuts that are easy to occur in casting; if forging machining is used, die forging requires a large-tonnage press, and the high temperature greatly shortens the life of components such as molds and workbenches, and the manufacturing cost of a single piece is greatly increased. For GH4099 alloy, an expensive metal material with high mechanical properties, tool wear is serious, machining is difficult and the cycle is long, and the material utilization rate is low, which increases the manufacturing cost. Traditional manufacturing technology is difficult to complete the manufacture of this type of structural parts efficiently and at low cost. The methods for manufacturing curved busbar components in the prior art are:

[0003] (1) The Chinese invention patent with publication number CN115740964A discloses a method for manufacturing a large-sized thin-walled curved busbar 5A06 aluminum alloy shell. The fan-shaped 5A06 aluminum alloy sheet is used as the raw material. The sheet is rolled into a cylinder by a plate rolling machine. The opposite sides of the cylinder are welded into shape by a welding process. The rolled welded cylinder is then heat treated to eliminate welding stress. The conical rolled welded cylinder is then spun to obtain a blank of target size. Finally, the product shape is fine-turned on a spinning machine to manufacture a large-sized thin-walled 5A06 aluminum alloy shell with a curved busbar shape. The specific manufacturing process is as follows: 1) blanking, 2) rolling, 3) welding, 4) heat treatment, 5) spinning, and 6) fine turning.

After the interface section and the center section are naturally cooled and sealed, the inner shaping tooling is inserted into the sealing clamping tooling that is still kept in the heated state, and the heating of the sealing clamping tooling is stopped. After the sealing clamping tooling is naturally cooled, the sealing is completed.

[0013] S2: Adjust the position of the laser welding device and the forging disc wheel so that they can perform additive welding on the fixed parts to be welded.

DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 7 A surface quality control device for additive manufacturing of a high-temperature alloy component is shown, comprising: a laser welding device 1, a forging disc wheel 5 and a sealing clamping tool 3 arranged in pairs, the sealing clamping tool 3 clamps an inner shaping tool whose outer wall is consistent with the inner wall structure of the section to be processed of the GH4099 curved busbar component 4, the outer wall of the inner shaping tool curved busbar segment 903 is consistent with the inner wall structure of the first curved busbar segment 404 and the second curved busbar segment 405, in this embodiment, the inner shaping tool comprises a first inner shaping tool 9 and a second inner shaping tool 10, the sealing clamping tool 3 is internally connected with a water-cooling temperature control device 8, the water-cooling temperature control device 8 is sequentially sealed and connected with the sealing clamping tool 3, the inner shaping tool and the hollow part to be welded to form a water-cooling circulation passage, in this embodiment, the complete water-cooling circulation passage sequentially comprises the water-cooling temperature control device 8 , sealing clamping tooling 3, a first internal shaping tooling 9, a central section 403, a second internal shaping tooling 10, a sealing clamping tooling 3 on the other side and a water-cooled temperature control device 8 on the other side; the forged disc wheel 5 is provided with the ability to move in the lateral, axial and height directions by the forged disc wheel driving device 6, the sealing clamping tooling 3 can be rotated and telescoped along the axis under the action of the tooling driving device 11, and the laser welding device 1 can move in the radial, axial and height directions driven by the robot arm 2. The above "axial" and "along the axis" refer to the central axis of the GH4099 curved busbar component as the axis. The hollow part to be welded includes an interface section and a central section, and the interface section includes a first interface section 401 and a second interface section 402; after assembly, the assembly relationship between the part to be welded and the sealing clamping tooling and the internal shaping tooling is an interference fit.

[0032] The GH4099 grade referred to in this embodiment is based on the standard GB / T 14992-2005 "Classification and grades of high-temperature alloys and intermetallic compound high-temperature materials", which means the nickel-based aging-strengthened alloy with the original grade GH99. Among them, "high-temperature alloy" is a common technical term in the industry, referring to a type of metal material based on iron, nickel, and cobalt that can work for a long time at a high temperature of more than 600°C and under certain stress.

[0033] The first interface section 401 , the second interface section 402 and the center section 403 are formed by bending and welding plates, and their corresponding welds are respectively the first interface section weld 406 , the second interface section weld 407 and the center section weld 408 .

[0034] In another embodiment of the present application, the material of the internal shaping tool is alumina ceramic, and the proportion of alumina in the alumina ceramic is higher than 85%. In order to adapt to the processing temperature of the GH4099 curved busbar component, alumina ceramic with a proportion of alumina higher than 85% is used as the internal shaping tool, and its heat-resistant temperature is above 1400°C, ensuring that the temperature of the alloy molten pool during welding will not affect the strength of the alumina ceramic.

[0035] like Figure 1 As shown, in another embodiment of the present application, the robot arm 2 is provided with an infrared temperature sensor capable of detecting the temperature of the alloy molten pool generated by the operation of the laser welding device, and the forging disc wheel is provided with a forging temperature sensor capable of detecting the temperature of the contact surface of the forging disc wheel.

[0036] like Figure 1 As shown, in another embodiment of the present application, the laser welding device 1 is a fiber laser with a power of 1200W-1500W, equipped with automatic wire feeding and argon protection functions, and the welding wire material is a nickel alloy with a grade of GH4099.

[0037] The present application also provides a method for controlling the surface quality of additively manufactured high-temperature alloy components, which is manufactured using any of the aforementioned devices for controlling the surface quality of additively manufactured high-temperature alloy components.

[0038] like Figure 3-Figure 6 As shown, in another embodiment of the present application, the following steps are included:

[0039] S1: Heat the hollow workpiece to be welded and the sealing clamping tool 3, insert the first interface section 401 of the workpiece to be welded into one end of the first inner shaping tool 9, and expose the reserved section of the first inner shaping tool 9 for clamping by the sealing clamping tool 3, and then put the central section 403 of the workpiece to be welded into the other end of the inner shaping tool, and perform the same operation on the second interface section 402 and the second inner shaping tool 10 on the opposite side, and after the first interface section 401, the second interface section 402 and the central section 403 are naturally cooled and sealed, insert the inner shaping tool into the sealing clamping tool 3 which is still kept in the heated state, stop heating the sealing clamping tool 3, and complete the sealing and fixing after the sealing clamping tool 3 is naturally cooled;

[0040] S2: Adjust the positions of the laser welding device 1 and the forging disc wheel 5 so that they can perform additive welding on the fixed parts to be welded. Turn on the water-cooling temperature control device 8 to introduce circulating water. The tooling driving device 11 rotates the sealing clamping tooling 3 to drive the parts to be welded and the internal shaping tooling to start rotating. The laser welding device 1 performs additive welding. The forging disc wheel 5 and the laser welding device 1 are kept consistent in the lateral direction for forging. After welding, remove the GH4099 curved busbar component 4 for heat treatment. After heat treatment, crush the internal shaping tooling and take it out. The GH4099 curved busbar component 4 is placed on the servo press. The elastic deformation of the GH4099 curved busbar component 4 is used to crush and take out the first internal shaping tooling 9 and the second internal shaping tooling 10.

[0041] The alloy molten pool 12 grows to form the weld 7, and the weld 7 grows to form the first curved mother line segment 404. At the same time, the disc wheel 5 and the internal shaping tooling curved mother line segment 903 rotate to forge the weld 7 cooled to the forging temperature. The second curved mother line segment 405 is prepared in the same way.

[0042] The welding process is carried out from the end with a smaller inner diameter of the workpiece to be welded to the end with a larger inner diameter of the workpiece to be welded. In this embodiment, the inner diameters of the first interface section 401 and the second interface section 402 are smaller than the inner diameter of the center section 403, so additive welding is carried out from the first interface section 401 to the center section 403, an alloy molten pool 12 is formed between the first interface section 401 and the first internal shaping tooling 9, and additive welding is carried out from the second interface section 402 to the center section 403.

[0043] The laser welding device 1 forms a molten pool on the outer wall of the first internal shaping tool 9 and the side of the first interface section 401. The molten pool grows to form the first curved busbar segment 404. The outer wall of the internal shaping tool curved busbar segment 903 and the GH4099 curved busbar component 4 form a ship-shaped groove to support the alloy molten pool 12. The forging disc wheel 5 and the internal shaping tool curved busbar segment 903 rotate to forge the weld 7 cooled to the forging temperature, so as to make the size of the weld 7 conform to the geometric shape of the first curved busbar segment 404.

[0044] like Figure 3 , Figure 4 and Figure 7 As shown, in another embodiment of the present application, step S1 heats the hollow parts to be welded and the sealing clamping tooling, and the heating temperature is 300-320°C. In this embodiment, the inner diameter of the first interface section 401 is 0.04mm smaller than the outer diameter of the inner shaping tooling small end tube 901 of the first inner shaping tooling 9, the inner diameter of the center section 403 is 0.04mm smaller than the outer diameter of the inner shaping tooling large end tube 902 of the first inner shaping tooling 9, and the inner diameter of the sealing clamping tooling 3 is 0.04mm smaller than the outer diameter of the inner shaping tooling small end tube 901 of the first inner shaping tooling 9. The hollow parts to be welded and the sealing clamping tooling expand before heating and after heating, so that the hollow parts to be welded and the sealing clamping tooling can be assembled with the inner shaping tooling, and an interference fit is formed after cooling. As a feasible alternative, the dimensional difference between the inner diameter of the first interface section 401, the inner diameter of the center section 403, the inner diameter of the sealing clamping tooling 3, the small end tube 901 of the first inner shaping tooling 9, and the large end tube 902 of the inner shaping tooling is determined by the precision of the processing equipment to ensure that a firm interference fit can be formed at room temperature and a water cooling circulation path can be realized.

[0045] like Figure 1 , Figure 4 and Figure 5 As shown, in another embodiment of the present application, the temperature of the alloy molten pool 12 is detected by an infrared temperature sensor, and the output power of the laser welding device 1 is adjusted according to the detected temperature, so that the temperature of the alloy molten pool 12 is controlled at 1325-1368°C. The contact surface temperature of the forging disc wheel 5 is detected by a forging temperature sensor, and the circulating water flow rate, the rotation speed of the sealing clamping tool 3 and the automatic wire feeding speed of the laser welding device 1 are adjusted according to the contact surface temperature, so that the contact surface temperature is controlled at 1100-1150°C. When the contact surface temperature is too high, the rotation speed of the sealing clamping tool 3 is reduced, and the automatic wire feeding speed of the laser welding device 1 is correspondingly reduced, and the circulating water flow rate is increased; when the contact surface temperature is too low, the rotation speed of the sealing clamping tool 3 is increased, and the automatic wire feeding speed of the laser welding device 1 is correspondingly increased, and the circulating water flow rate is reduced.

[0046] In another embodiment of the present application, the heat treatment temperature is 750° C.-760° C., and the duration is 8 to 9 hours. The heat treatment effectively eliminates welding stress and avoids cracks at the weld.

[0047] like Figure 1As shown, in another embodiment of the present application, during the process of crushing and removing the internal shaping tooling in step S2, a protective tooling having an inner wall having the same shape and size as the outer wall of the processed GH4099 curved busbar component 4 is used, and is sleeved on the outside of the GH4099 curved busbar component 4 at a position corresponding to the internal shaping tooling; during the process of removing the GH4099 curved busbar component, the sealing clamping devices on both sides are heated to 300-320°C before taking out the components.

[0048] like Figure 8 As shown, the GH4099 curved busbar component 4 is fixed at the test fixture 13, and the high-temperature tensile performance test is carried out according to the GB / T 228.2-2015 standard using the NCS-R46 tensile testing machine (the tensile testing machine is provided by the Steel Research Institute Nake Testing Center). The test temperatures are room temperature, 700°C and 900°C. Before the test, the tensile specimen needs to be kept in the furnace for 15 minutes so that the temperature difference at the specimen in the furnace does not exceed ±2°C. The high-temperature tensile rate is 0.5mm / min before the end of yielding and 2.5mm / min after the end of yielding.

[0049] After testing, the weld strength at room temperature reaches 1100MPa, the high temperature strength at 700℃ reaches 630MPa, and the high temperature strength at 900℃ reaches 380MPa. The internal and external quality of the weld are tested by X-ray and fluorescence detection respectively, and the weld is free of defects.

[0050] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
