Description

Technical Field

[0001] The invention belongs to the field of production of hot end components of aviation engines, in particular to a spinning integral molding device for hot end components of aviation engines. Background Art

[0002] Aircraft engine hot-end components are those directly exposed to high-temperature combustion gases during engine operation. Located in the engine's hottest and harshest operating environments, these components have a crucial impact on the engine's performance, reliability, and durability. Their primary components include turbine blades, combustion chambers, and turbine disks. The turbine blades are one of the most critical components in an aircraft engine's hot-end, converting the energy of the high-temperature combustion gases into mechanical energy to drive the compressor and other accessories. The combustion chamber is where the fuel and air mix and burn, while the turbine disk supports the turbine blades and transmits torque. The combustion chamber is typically produced using a spinning machine, which forms metal sheets. This type of combustion chamber boasts high dimensional accuracy and high material utilization.

[0003] In the existing technology, when spinning the blank metal plate of the combustion chamber, due to the very high hardness of the spinning wheel, it is very easy to cause scratches on the surface of the metal plate when pressure is applied to the metal plate to deform it, affecting the smoothness of the metal. In addition, there is severe friction between the spinning wheel and the metal plate. The spinning wheel applies pressure to the metal plate and causes it to plastically deform. During this process, the contact area between the metal plate surface and the spinning wheel will generate a large amount of heat due to the work done by friction, causing the metal plate to overheat, thereby changing the hardness of the metal plate and reducing the strength of the metal plate.

[0004] To this end, the present invention provides a spinning integral molding device for the hot end components of an aero-engine. Summary of the Invention

[0036] Through the above technical solution, the metal plate is fixed by the suction cup 10, the first motor 4 is started, the first screw rod 5 is driven to rotate, the first slider 6 is moved closer to the mold 3, the support plate 7 is driven closer to the mold 3, and the metal plate is attached to the mold 3. The second motor 8 is started to drive the suction cup 10 to rotate, the metal plate is rotated, the position of the spinning is adjusted, the third motor 11 is started to drive the second screw rod 12 to rotate, the second slider 13 is moved closer to the metal plate, the rotating wheel 17 is driven closer to the metal plate, and the fourth motor 1 is started. 6, drives the rotating wheel 17 to rotate, which is convenient for spinning the metal plate. While spinning the metal plate, the rotating wheel 17 is controlled by the third motor 11 to move back and forth. Through multiple spinning, the combustion chamber is formed. The hydraulic cylinder 14 is started to drive the rotating wheel 17 to move downward, which is convenient for adjusting the bending position of the metal plate. Lubricant is loaded into the first cavity 18 through the liquid injection port 19. When the rotating wheel 17 spins the metal plate, lubricant is added to the rotating wheel 17 through the lubricating component to prevent the rotating wheel 17 from scratching the surface of the metal plate.

[0037] Specifically, the lubrication assembly includes an injection groove 27, which is opened inside the fixed frame 15. The inner wall of the fixed frame 15 is fixedly connected to a first pipe 28, the top of the first pipe 28 extends to the inside of the injection groove 27, the inner wall of the first pipe 28 is slidably connected to a second pipe 29, the bottom of the second pipe 29 is connected to a hose 30, one end of the hose 30 extends to the inside of the first cavity 18, and the outer wall of the second pipe 29 is provided with a linkage unit.

[0038] Through the above technical solution, while the third motor 11 controls the reciprocating left and right movement of the fixed frame 15, the linkage unit cooperates to allow the lubricant in the first cavity 18 to flow into the second pipe 29 along the hose 30. The lubricant entering the second pipe 29 flows into the fixed frame 15 along the first pipe 28 and the liquid injection groove 27, thereby adding lubricant to the rotating wheel 17.

[0039] Specifically, the linkage unit includes a first box 31, which is fixedly mounted on the outer wall of the second pipe 29. The inner wall of the first box 31 is slidably connected to a first piston plate 32, and one side of the first piston plate 32 is fixedly connected to a first piston rod 33. One end of the first piston rod 33 passes through the first box 31 and is fixedly connected to the box body 1. Two first one-way valves 34 are symmetrically arranged on the inner wall of the second pipe 29 with the first box 31 as the center, and the two first one-way valves 34 are both opened from bottom to top.

[0040] Through the above technical solution, when the fixing frame 15 moves to the left, the first pipe 28 and the second pipe 29 are driven to move to the left. Under the pulling of the first piston rod 33, the first piston plate 32 slides in the first set box 31. Through the pulling of the first piston plate 32, the two first one-way valves 34 opened from the bottom to the top are cooperated to make the lubricant in the first cavity 18 enter the first set box 31 along the hose 30 and the second pipe 29. When the fixing frame 15 moves to the right, the first pipe 28 and the second pipe 29 are driven to move to the right, so that the first piston plate 32 squeezes the lubricant in the first set box 31. The two first one-way valves 34 opened from the bottom to the top are cooperated to make the lubricant in the first set box 31 flow upward along the first pipe 28. In this way, when the fixing frame 15 moves left and right, the lubricant can be continuously transported upward.

[0041] Specifically, the inner wall of the fixed frame 15 is fixedly connected to a fixed plate 20, and the inner wall of the fixed plate 20 is symmetrically slidably connected to two sliding shafts 21, one end of the two sliding shafts 21 is fixedly connected to a limiting plate 24, and the other end of the two sliding shafts 21 is fixedly connected to a mounting plate 22. The outer walls of the two sliding shafts 21 are each sleeved with a spring 25, one end of the spring 25 is fixedly connected to the mounting plate 22, and the other end of the spring 25 is fixedly connected to the fixed plate 20. A sponge pad 23 is fixedly connected to the side of the mounting plate 22 close to the rotating wheel 17, and an arc-shaped groove 52 is provided on the outer wall of the sponge pad 23. The rotating wheel 17 fits into the inner wall of the arc-shaped groove 52. The other end of the mounting plate 22 is fixedly connected to a connecting pipe 26, which is slidably connected to the fixed plate 20 and one end of which extends to the inside of the liquid injection tank 27.

[0042] Through the above technical solution, the spring 25 is provided to make the sponge pad 23 press against the rotating wheel 17, so that the rotating wheel 17 rotates while keeping in contact with the inner wall of the arc groove 52. The lubricant entering the injection groove 27 flows along the injection groove 27 and the connecting pipe 26 and soaks into the sponge pad 23. Through the coating of the sponge pad 23 and the rotation of the rotating wheel 17, the contact position between the rotating wheel 17 and the metal plate is kept lubricated to avoid scratching the metal plate.

[0043] Specifically, a second cavity 35 is opened at the top of the inner wall of the box body 1, and a third pipe 36 is fixedly connected to the inner wall of the second cavity 35. One end of the third pipe 36 passes through the second cavity 35 and is fixedly connected to an annular plate 37. A reflux unit is provided inside the annular plate 37, and a drive component is provided on the outer wall of the third pipe 36.

[0044] Through the above technical solution, refrigerant is loaded into the second cavity 35. While the hydraulic cylinder 14 is controlled to move back and forth left and right by the third motor 11, the driving component is simultaneously driven to make the refrigerant in the second cavity 35 enter the annular plate 37 along the third pipe 36. The annular plate 37 is cooled by the refrigerant, and then the metal plate being spun is cooled to avoid overheating of the metal plate and affecting its strength. The refrigerant entering the annular plate 37 can re-enter the second cavity 35 through the reflux unit, so that the refrigerant can be recycled to avoid excessive waste of refrigerant.

[0045] Specifically, the reflux unit includes a first circulation groove 38, which is arranged in an annular shape and is opened on the outer wall of the annular plate 37. A second circulation groove 39 is opened on the outer wall of the mold 3, and the second circulation groove 39 is arranged in an annular shape. The annular plate 37 fits the inner wall of the second circulation groove 39. The third pipe 36 is communicated with the first circulation groove 38. The outer wall of the annular plate 37 is fixedly connected to the fourth pipe 44. One end of the fourth pipe 44 extends to the interior of the second cavity 35. The other end of the fourth pipe 44 is communicated with the first circulation groove 38. The inner wall of the fourth pipe 44 is provided with a third one-way valve 45, and the third one-way valve 45 is opened from bottom to top.

[0046] Through the above technical solution, the refrigerant flowing downward through the third pipe 36 enters the first circulation groove 38 in the annular plate 37, and enters the second circulation groove 39 along the first circulation groove 38. The refrigerant flowing in the second circulation groove 39 can cool the position where the metal plate is spun and deformed, ensuring that each position of the metal plate can be cooled. The third one-way valve 45 opened from bottom to top prevents the refrigerant in the second cavity 35 from entering the fourth pipe 44.

[0047] Specifically, the drive assembly includes a second box 40, which is fixedly mounted on the outer wall of the third pipe 36. The inner wall of the second box 40 is slidably connected to a second piston plate 41. One side of the second piston plate 41 is fixedly connected to a second piston rod 42. One end of the second piston rod 42 passes through the second box 40 and is fixedly connected to the hydraulic cylinder 14. The inner wall of the third pipe 36 is symmetrically provided with two second one-way valves 43 with the second box 40 as the center. The two second one-way valves 43 are both opened from top to bottom. A pressure relief groove 47 is provided on the outer wall of the box body 1, and the pressure relief groove 47 is communicated with the second cavity 35.

[0048] Through the above technical solution, when the hydraulic cylinder 14 moves to the right, it drives the second piston rod 42 to move to the right, so that the second piston plate 41 moves to the right. By pulling the second piston plate 41, the two first one-way valves 34 are opened from top to bottom, so that the refrigerant in the second cavity 35 enters the second set box 40 along the third pipe 36. When the hydraulic cylinder 14 moves to the left, it pushes the second piston rod 42 to move to the left, so that the second piston plate 41 moves to the left. By squeezing the second piston plate 41, the two first one-way valves 34 are opened from top to bottom, so that the refrigerant in the second set box 40 The refrigerant flows along the third pipe 36 into the annular plate 37, and the pressure relief groove 47 is used to help the second cavity 35 to relieve pressure, so that the pressure in the second cavity 35 is balanced. Thus, when the hydraulic cylinder 14 moves left and right, the refrigerant can be continuously injected into the second circulation groove 39. When the second circulation groove 39 and the first circulation groove 38 are filled with refrigerant, as the second piston plate 41 is squeezed, the refrigerant in the second circulation groove 39 and the first circulation groove 38 flows upward along the fourth pipe 44 and re-enters the second cavity 35, thereby allowing the refrigerant to be recycled.

[0049] Specifically, a mounting bracket 48 is fixedly connected to the interior of the box 1, an annular bracket 49 is fixedly connected to one end of the mounting bracket 48, a sponge 50 is fixedly connected to the inner wall of the annular bracket 49, and the sponge 50 is arranged in an annular shape and has an annular inclined surface on its inner wall.

[0050] Through the above technical solution, after the spinning of the metal plate is completed, the support plate 7 is controlled to move back by the first motor 4, and the metal plate is driven to be demolded from the mold 3 by the pulling of the suction cup 10. As the support plate 7 moves, the metal plate is driven to be replaced from the annular frame 49. The annular sponge 50 is provided to wipe the position of the metal plate that has been deformed by spinning, helping to remove the lubricant adhering to the metal plate.

[0051] Specifically, a refrigerator 46 is provided on the outer wall of the box body 1 , and a cooling end of the refrigerator 46 extends into the interior of the second cavity 35 and is fixedly connected to a plurality of metal fins 53 at equal intervals.

[0052] Through the above technical solution, the refrigerant in the second cavity 35 is cooled by the refrigerator 46, so that the refrigerant that has been heated up after one cycle is cooled again to maintain the cooling effect of the refrigerant during the circulation. By setting up several metal fins 53, the cooling range of the refrigerator 46 can be increased and the cooling of the refrigerant can be accelerated.

[0053] Specifically, a plurality of sponge protrusions 51 are fixedly connected to the inclined surface of the inner wall of the sponge 50 at equal intervals.

[0054] Through the above technical solution, when the metal plate after spinning deformation is moved into the annular frame 49, the second motor 8 is started to drive the suction cup 10 to rotate, so that the metal plate rotates. Through the provision of several sponge protrusions 51, the lubricant adhering to the surface of the metal plate can be cleaned more carefully.

[0055] During use, lubricant is filled into the first cavity 18 through the liquid injection port 19, and refrigerant is filled into the second cavity 35. The metal plate is fixed by the suction cup 10, and the first motor 4 is started to drive the first screw rod 5 to rotate, so that the first slider 6 approaches the mold 3, and the support plate 7 approaches the mold 3, so that the metal plate is attached to the mold 3. The second motor 8 is started to drive the suction cup 10 to rotate, so that the metal plate rotates and the spinning position is adjusted. The third motor 11 is started to drive the second screw rod 12 to rotate, so that the second slider 13 approaches the metal plate, and the rotating wheel 17 approaches the metal plate. The fourth motor 16 is started to drive the rotating wheel 17 to rotate, so as to facilitate the spinning of the metal plate. While the metal plate is spinning, the rotating wheel 17 is controlled by the third motor 11 to move back and forth left and right. The combustion chamber is formed by multiple spinning, and the hydraulic cylinder 14 is started to drive the rotating wheel 17 to move downward to facilitate the adjustment of the bending position of the metal plate. When the fixing frame 15 moves to the left, the first pipe 28 and the second pipe 29 are driven to move to the left. Under the pull of the first piston rod 33, the first piston plate 32 slides in the first set box 31. By pulling the first piston plate 32, the two first one-way valves 34 opened from bottom to top are cooperated to make the lubricant in the first cavity 18 enter the first set box 31 along the hose 30 and the second pipe 29. When the fixing frame 15 moves to the right, the first pipe 28 and the second pipe 29 are driven to move to the right, so that the first piston plate 32 squeezes the lubricant in the first set box 31, and cooperates with the two first one-way valves 34 opened from bottom to top. A one-way valve 34 allows the lubricant in the first set box 31 to flow upward along the first pipe 28, and thus reciprocates. When the fixed frame 15 moves left and right, the lubricant can be continuously transported upward, so that the lubricant enters the injection groove 27 along the first pipe 28. The spring 25 is provided to make the sponge pad 23 press against the rotating wheel 17, so that the rotating wheel 17 rotates while keeping in contact with the inner wall of the arc groove 52. The lubricant entering the injection groove 27 flows along the injection groove 27 and the connecting pipe 26, and is soaked in the sponge pad 23. The contact position between the rotating wheel 17 and the metal plate is kept lubricated by the smearing of the sponge pad 23 and the rotation of the rotating wheel 17, thereby avoiding scratching the metal plate. When the hydraulic cylinder 14 moves to the right, it drives the second piston rod 42 to move to the right, so that the second piston rod 42 The plug plate 41 moves to the right, and through the pulling of the second piston plate 41, the two first one-way valves 34 opened from top to bottom are cooperated to make the refrigerant in the second cavity 35 enter the second set box 40 along the third pipe 36. When the hydraulic cylinder 14 moves to the left, it pushes the second piston rod 42 to move to the left, making the second piston plate 41 move to the left. Through the squeezing of the second piston plate 41, the two first one-way valves 34 opened from top to bottom are cooperated to make the refrigerant in the second set box 40 flow along the third pipe 36 into the annular plate 37. The pressure relief groove 47 provided is used to help the second cavity 35 to relieve pressure, so that the pressure in the second cavity 35 is balanced. Thus, when the hydraulic cylinder 14 moves left and right, the refrigerant can be continuously injected into the second circulation groove 39.By circulating the refrigerant in the second circulation groove 39, the position where the metal plate is spun and deformed can be cooled, ensuring that every position of the metal plate can be cooled. The third one-way valve 45 opened from bottom to top prevents the refrigerant in the second cavity 35 from entering the fourth pipe 44. When the second circulation groove 39 and the first circulation groove 38 are filled with refrigerant, as the second piston plate 41 is squeezed, the refrigerant in the second circulation groove 39 and the first circulation groove 38 flows upward along the fourth pipe 44 and re-enters the second cavity 35, thereby allowing the refrigerant to be circulated. The refrigerant in the second cavity 35 is refrigerated by the refrigerator 46, so that the refrigerant that has heated up after a cycle is cooled again to maintain the controllable temperature of the refrigerant during circulation. The cooling effect is achieved by providing a plurality of metal fins 53, which can increase the cooling range of the refrigerator 46 and accelerate the cooling of the refrigerant. After the metal plate is spun, the first motor 4 controls the support plate 7 to move back. The suction cup 10 pulls the metal plate to remove it from the mold 3. As the support plate 7 moves, the metal plate is moved out of the annular frame 49. The annular sponge 50 can wipe the position of the metal plate where it was spun and deformed, helping to remove the lubricant adhering to the metal plate. When the spun metal plate moves into the annular frame 49, the second motor 8 is started to drive the suction cup 10 to rotate, causing the metal plate to rotate. The plurality of sponge protrusions 51 can clean the lubricant adhering to the surface of the metal plate more carefully.
