Description

Technical Field

[0001] The present application relates to the technical field of turbine blades, and specifically relates to a turbine blade casting device. Background Art

[0002] As a key component of an engine, the turbine working blade is located in the most severe part of the engine environment and plays an extremely crucial role in both aircraft engines and gas turbines. During operation, it needs to withstand high temperatures and high centrifugal loads. To improve the performance of the engine, increasing the front inlet temperature is a key indicator. When producing turbine blades, casting is required.

[0003] For example, the application with the publication number CN117259685A discloses a blade positioning reference casting mold for preparing a positioning reference on the outer periphery of a blade in an aeroengine. The blade positioning reference casting mold includes a lower mold, a positioning mechanism, an upper mold, and a quick-release mechanism. The lower mold is provided with a clamping position for installing the blade. The positioning mechanism includes two positioning blocks slidably disposed in the lower mold. The quick-release mechanism is respectively connected to the upper mold and the lower mold and is used to lock and fix the upper mold relative to the lower mold. The blade positioning reference casting mold provided by the present invention can form a positioning reference on the outer periphery of the blade that is convenient for clamping and positioning, and use the positioning reference to clamp and position the blade, simplifying the clamping process and improving the clamping efficiency and accuracy.

[0004] Although the above technical solution improves the function of clamping efficiency, there are still other problems in specific use. For example, when casting, it is necessary to introduce molten liquid into the casting cavity, that is, it is necessary to completely dock the discharge pipe and the feed pipe so as to avoid the molten liquid falling to other positions on the rest of the casting table. However, it is rather troublesome to dock the two pipes.

[0005] Therefore, it is necessary to provide a turbine blade casting device to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

[0050] 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. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0052] like Figures 1 to 6 As shown, the present application provides a turbine blade casting device, comprising: a workbench 1; a receiving disc 2, the receiving disc 2 is rotatably arranged above the workbench 1 through a rotating shaft, and the rotating shaft is connected to the output end of an external motor; a plurality of placement plates 3, a plurality of the placement plates 3 are arranged in a circular array on the upper end surface of the receiving disc 2; the upper end surface of each of the placement plates 3 is provided with a casting plate 1 301 and a casting plate 2 302, and a blade casting is formed between the casting plate 1 301 and the casting plate 2 302. Cavity making; a liquid storage cavity seat 4, the liquid storage cavity seat 4 is installed above the workbench 1 through a side bracket; the lower end surface of the liquid storage cavity seat 4 is provided with a liquid outlet pipe 401; a butt joint pipe 5, the butt joint pipe 5 is installed on the upper end surface of each of the casting plate 1 301 and the casting plate 2 302, and the shape of the butt joint pipe 5 is semi-cylindrical; a butt joint component, the butt joint component is arranged on the side wall of the liquid storage cavity seat 4, and the butt joint component is used to control the liquid outlet pipe 401 to move to one side of the butt joint pipe 5;

[0053] During operation, in the initial state, the docking pipes 5 on the upper end surface of the casting plate 1 301 are in contact with the docking pipes 5 on the upper end surface of the casting plate 2 302. Subsequently, the external motor output end is controlled to drive the receiving disc 2 to rotate, so that the receiving disc 2 drives one of the placement plates 3 above it to move towards the side close to the liquid storage cavity seat 4. When one of the placement plates 3 moves to correspond to the liquid outlet pipe fitting 401, at this time, under the action of the docking assembly, the liquid outlet pipe fitting 401 at the bottom of the liquid storage cavity seat 4 will move towards the side of the combined docking pipes 5. Then, the molten liquid inside the liquid storage cavity seat 4 will enter the docking pipes 5 from the inside of the liquid outlet pipe fitting 401, and then enter the cavity between the casting plate 1 301 and the casting plate 2 302. Then, the liquid outlet pipe fitting 401 of the docking assembly is controlled to move away from the docking pipes 5, and under the continuous rotation of the receiving disc 2, the casting plate 1 301 and the casting plate 2 302 containing the molten liquid will continue to rotate.

[0054] The docking assembly includes: a contact point 1 6, which is installed on the side wall of the liquid storage cavity seat 4; a contact point 2 7, which is installed on the side wall of the casting plate 2 302. During the rotation of the casting plate 2 302 following the receiving disc 2, the contact point 2 7 will contact the contact point 1 6; a trigger unit, which is arranged above the placement plate 3 and is used to control the movement of the liquid outlet pipe fitting 401.

[0055] During operation, when one pair of the casting plate 1 301 and the casting plate 2 302 rotate following the receiving disc 2, that is, when moving towards the side close to the liquid storage cavity seat 4, until the liquid outlet pipe fitting 401 and the docking pipes 5 are aligned, at this time, the contact point 2 7 on the side wall of the casting plate 2 302 will contact the contact point 1 6 on the side wall of the liquid storage cavity seat 4, and the external circuit is connected. Thus, the external controller will control the liquid outlet pipe fitting 401 at the bottom of the liquid storage cavity seat 4 to move towards the side close to the docking pipes 5, so as to achieve the automatic docking of the liquid outlet pipe fitting 401 and the docking pipes 5, and avoid the problem that the molten liquid spills outside the workbench 1; when the molten liquid inside the casting plate 1 301 and the casting plate 2 302 reaches a certain level, under the action of the trigger unit, the liquid outlet pipe fitting 401 will move away from the docking pipes 5, thus facilitating the subsequent continuous casting of the remaining casting plate 1 301 and the casting plate 2 302.

[0056] As Figures 3 to 7 shown, the trigger unit includes: a sliding plate 8, which is slidably arranged on the upper end surface of the placement plate 3, and the casting plate 1 301 and the casting plate 2 302 are arranged above the sliding plate 8; a contact point 3 9, which is fixedly installed on the lower end surface of the sliding plate 8; a contact point 4 10, which is fixedly installed on the upper end surface of the placement plate 3; a plurality of elastic telescopic rods 11, one end of the elastic telescopic rods 11 is connected to the lower end surface of the sliding plate 8, and the other end is connected to the upper end surface of the placement plate 3.

[0057] During operation, in the initial state, that is, when the molten liquid has not yet been introduced into the first casting plate 301 and the second casting plate 302, the third contact 9 and the fourth contact 10 do not touch; after the liquid outlet pipe fitting 401 and the docking pipe 5 are docked, as the molten liquid in the cavity between the first casting plate 301 and the second casting plate 302 increases, the gravity of the first casting plate 301, the second casting plate 302, and the sliding plate 8 gradually becomes greater than the supporting force of all the elastic telescopic rods 11. Therefore, the sliding plate 8 will move downward. After the molten liquid is completely introduced into the first casting plate 301 and the second casting plate 302, at this time, the sliding plate 8 just drives the third contact 9 to move to one side of the fourth contact 10 on the upper end surface of the placement plate 3. At this time, the third contact 9 and the fourth contact 10 are in contact, and the external circuit is connected. The external controller will first control the liquid outlet pipe fitting 401 to move away from the docking pipe 5, and then control the receiving disc 2 to continue rotating, and make the first casting plate 301 and the second casting plate 302 into which the molten liquid has been introduced rotate to the other side, facilitating the subsequent formation of the turbine blade and taking it out.

[0058] A limiting groove adapted to the elastic telescopic rod 11 is provided on the upper end surface of the placement plate 3, and a telescopic spring 12 is sleeved on the outer peripheral surface of the elastic telescopic rod 11; during operation, the provision of the limiting groove can facilitate the sliding plate 8 to press down the elastic telescopic rod 11 and enable the subsequent third contact 9 and the fourth contact 10 to come into contact. Moreover, under the action of the telescopic spring 12, it is convenient to support the sliding plate 8.

[0059] The docking assembly further includes: a fixing plate 13, which is fixedly installed on the lower side of the liquid storage cavity seat 4; an L-shaped electric telescopic rod 14, which is fixedly installed below the fixing plate 13, and the end of the L-shaped electric telescopic rod 14 away from the fixing plate 13 is connected to the side wall of the liquid outlet pipe fitting 401;

[0060] During operation, when the first contact 6 and the second contact 7 are in contact, that is, when the external circuit is connected, and at this time, the two corresponding docking pipes 5 are closed together. Subsequently, the L-shaped electric telescopic rod 14 is powered on, so that the L-shaped electric telescopic rod 14 drives the liquid outlet pipe fitting 401 to move towards the side of the closed docking pipe 5, thus facilitating the introduction of the molten liquid into the first casting plate 301 and the second casting plate 302; as the weight of the sliding plate 8, the first casting plate 301, and the second casting plate 302 gradually increases, when the sliding plate 8 moves downward, the second contact 7 on the side wall of the second casting plate 302 will gradually separate from the first contact 6, and gradually the third contact 9 and the fourth contact 10 will come into contact. When the latter two are in contact, at this time, the external circuit is connected, and the L-shaped electric telescopic rod 14 will be controlled to drive the liquid outlet pipe fitting 401 to move upward, so that the liquid outlet pipe fitting 401 gradually moves away from the docking pipe 5. Subsequently, the controller will control the receiving disc 2 to rotate, so that it is convenient for the subsequent first casting plate 301 and the second casting plate 302 to continue casting the turbine blade.

[0061] As shown Figures 3 to 9 As shown, the liquid outlet pipe fitting 401 includes: a contact pipe 15 which is slidably arranged on the inner wall of the liquid outlet pipe fitting 401, and a seal is provided at the contact position between the contact pipe 15 and the liquid outlet pipe fitting 401; the telescopic end of the L-shaped electric telescopic rod 14 is connected to the side wall of the contact pipe 15; folding sealing plates 16, two folding sealing plates 16 are designed, and they are symmetrically rotatably arranged on the inner wall of the liquid outlet pipe fitting 401. When the two folding sealing plates 16 are combined, they will completely seal the inner wall of the liquid outlet pipe fitting 401; a pull rod 17, one end of the pull rod 17 is ball-jointed to the side wall of the folding sealing plate 16, and the other end is ball-jointed to the inner wall of the contact pipe 15.

[0062] During operation, in the initial state, that is, when the liquid outlet pipe fitting 401 has not contacted the docking pipe 5 yet, at this time the two folding sealing plates 16 are closed together and will block the liquid outlet pipe fitting 401, so that the molten liquid in the liquid storage cavity seat 4 will not flow out from the inside of the liquid outlet pipe fitting 401; when the liquid outlet pipe fitting 401 and the docking pipe 5 are aligned, and the L-shaped electric telescopic rod 14 drives the contact pipe 15 to move downward, the contact pipe 15 will drive the pull rod 17 to move at the same time. When the bottom end of the contact pipe 15 extends into the docking pipe 5, the two folding sealing plates 16 are just pulled open. At this time, the molten liquid above the liquid outlet pipe fitting 401 will enter the casting plate one 301 and the casting plate two 302 along the docking pipe 5, realizing the casting of the turbine blade.

[0063] The casting plate two 302 is slidably arranged above the sliding plate 8, and a pushing-away unit is arranged above the sliding plate 8. The pushing-away unit is used to control the casting plate two 302 to move away from the casting plate one 301; during operation, when the molten liquid of the turbine blade gradually takes shape inside the casting plate one 301 and the casting plate two 302, and with the rotation of the receiving disc 2, it will cause the pushing-away unit to drive the casting plate two 302 to move away from the casting plate one 301, and then it is convenient to take out the formed turbine blade.

[0064] The pushing-away unit includes a slider 18 slidably arranged above the sliding plate 8. The end of the slider 18 is connected to the side wall of the casting plate one 301. A linkage frame 19 is installed at the end of the slider 18. A limiting frame 20 is rotatably arranged at the corresponding position on the side wall of the workbench 1 with respect to the linkage frame 19. During the process of the linkage frame 19 following the rotation of the receiving disc 2, the end of the linkage frame 19 will contact the end of the limiting frame 20.

[0065] During operation, when the casting plate 1 - 301 and the casting plate 2 - 302 containing the molten liquid rotate following the receiving disc 2, the casting plate 1 - 301 will drive the linkage frame 19 to move simultaneously. And the linkage frame 19 will gradually come into contact with the limiting frame 20. Under the limitation of the limiting frame 20, the linkage frame 19 will drive the slider 18 to move a certain distance. At this time, the next pair of the casting plate 1 - 301 and the casting plate 2 - 302 also just move to the side corresponding to the liquid outlet pipe fitting 401. At this time, the receiving disc 2 also just stops rotating. At this time, the slider 18 has driven the casting plate 1 - 301 away from the casting plate 2 - 302, and the formed blade is exposed at this time. Therefore, it is convenient for the subsequent staff to take out the formed blade, and the operation is relatively convenient.

[0066] A limiting column 21 is installed at the position corresponding to the limiting frame 20 on the side wall of the workbench 1. A chute adapted to the slider 18 is provided on the upper end surface of the sliding plate 8. During operation, when the limiting frame 20 and the linkage frame 19 come into contact, under the pressure of the linkage frame 19, the limiting frame 20 will rotate in the direction away from the linkage frame 19. And under the limitation of the limiting column 21, the rotation position of the limiting frame 20 can be limited. In this way, it is convenient for the subsequent linkage frame 19 to disengage from the limiting frame 20, and it is beneficial to take out the formed blade inside the subsequent casting plate 1 - 301 and the casting plate 2 - 302.

[0067] A telescopic column 22 is installed on the side wall of the slider 18. A spring is sleeved on the outer surface of the telescopic column 22. The end of the telescopic column 22 is connected to the side wall of the sliding plate 8. During operation, when the slider 18 moves, it will simultaneously compress the telescopic column 22 and the spring on its side wall. And under the pressure of the limiting column 21, it can give the staff enough time to take out the formed blade. At the same time, after the linkage frame 19 is separated from the limiting frame 20, it is convenient for the slider 18 to drive the casting plate 1 - 301 to return to the initial position.

[0068] Working principle: In the initial state, the docking pipe 5 on the upper end surface of the casting plate 1 301 is in contact with the docking pipe 5 on the upper end surface of the casting plate 2 302. Subsequently, the external motor output end is controlled to drive the receiving disc 2 to rotate, so that the receiving disc 2 drives one of the placing plates 3 above it to move towards the side close to the liquid storage cavity seat 4. When one of the placing plates 3 moves to correspond to the liquid outlet pipe fitting 401, under the action of the docking assembly, the liquid outlet pipe fitting 401 at the bottom of the liquid storage cavity seat 4 will move towards the side of the combined docking pipes 5. Then, the molten liquid inside the liquid storage cavity seat 4 will enter the docking pipe 5 from the inside of the liquid outlet pipe fitting 401, and then enter the cavity between the casting plate 1 301 and the casting plate 2 302. Then, the liquid outlet pipe fitting 401 of the docking assembly is controlled to move away from the docking pipe 5, and with the continuous rotation of the receiving disc 2, the casting plate 1 301 and the casting plate 2 containing the molten liquid will continue to rotate; when a pair of the casting plate 1 301 and the casting plate 2 follow the receiving disc 2 during rotation, that is, when moving towards the side close to the liquid storage cavity seat 4, until the liquid outlet pipe fitting 401 and the docking pipe 5 are aligned, at this time, the contact point two 7 on the side wall of the casting plate 2 will contact the contact point one 6 on the side wall of the liquid storage cavity seat 4, and the external circuit is connected. Thus, the external controller will control the liquid outlet pipe fitting 401 at the bottom of the liquid storage cavity seat 4 to move towards the side close to the docking pipe 5, so as to realize the automatic docking of the liquid outlet pipe fitting 401 and the docking pipe 5, and avoid the problem of molten liquid spilling outside the workbench 1; when the molten liquid inside the casting plate 1 301 and the casting plate 2 reaches a certain level, under the action of the triggering unit, the liquid outlet pipe fitting 401 will move away from the docking pipe 5 again, facilitating the subsequent continuous casting of the remaining casting plate 1 301 and the casting plate 2;

[0069] In the initial state, that is, before the molten liquid is introduced into the casting plate 1 301 and the casting plate 2, that is, the contact point three 9 and the contact point four 10 do not contact; after the docking of the liquid outlet pipe fitting 401 and the docking pipe 5 is completed, as the molten liquid in the cavity between the casting plate 1 301 and the casting plate 2 increases, the gravity of the casting plate 1 301, the casting plate 2, and the sliding plate 8 gradually becomes greater than the supporting force of all the elastic telescopic rods 11. Therefore, the sliding plate 8 will move downward. After the molten liquid is introduced into the casting plate 1 301 and the casting plate 2, at this time, the sliding plate 8 just drives the contact point three 9 to move to one side of the contact point four 10 on the upper end surface of the placing plate 3. At this time, the contact point three 9 and the contact point four 10 contact, and the external circuit is connected. The external controller will first control the liquid outlet pipe fitting 401 to move away from the docking pipe 5, and then control the receiving disc 2 to continue to rotate, and make the casting plate 1 301 and the casting plate 2 into which the molten liquid has been introduced rotate to the other side, facilitating the subsequent forming and taking out of the turbine blades;

[0070] When the first contact 6 and the second contact 7 are in contact, that is, when the external circuit is connected, and at this time the two corresponding butting pipes 5 are closed together, then the L-shaped electric telescopic rod 14 is energized, so that the L-shaped electric telescopic rod 14 drives the liquid outlet pipe fitting 401 to move towards the side of the butting pipes 5 that are closed together, thus facilitating the molten liquid to flow into the first casting plate 301 and the second casting plate 302; as the weights of the sliding plate 8, the first casting plate 301 and the second casting plate 302 gradually increase, when the sliding plate 8 moves downward, the second contact 7 on the side wall of the second casting plate 302 will gradually separate from the first contact 6, and gradually the third contact 9 will contact the fourth contact 10. When the latter two are in contact, at this time the external circuit is connected, and the L-shaped electric telescopic rod 14 will be controlled to drive the liquid outlet pipe fitting 401 to move upward first, so that the liquid outlet pipe fitting 401 gradually moves away from the butting pipes 5, and then the controller will control the receiving disc 2 to rotate again, so as to facilitate the subsequent casting of the first casting plate 301 and the second casting plate 302 on the turbine blade;

[0071] In the initial state, that is, when the liquid outlet pipe fitting 401 has not contacted the butting pipes 5, at this time the two folding sealing plates 16 are closed together, and will block the liquid outlet pipe fitting 401, so that the molten liquid in the liquid storage cavity seat 4 will not flow out from the inside of the liquid outlet pipe fitting 401; after the liquid outlet pipe fitting 401 and the butting pipes 5 are aligned, and when the L-shaped electric telescopic rod 14 drives the contact pipe 15 to move downward, the contact pipe 15 will drive the pull rod 17 to move at the same time. When the bottom end of the contact pipe 15 extends into the butting pipes 5, the two folding sealing plates 16 are just pulled open, and at this time the molten liquid above the liquid outlet pipe fitting 401 will enter the first casting plate 301 and the second casting plate 302 along the butting pipes 5, realizing the casting of the turbine blade;

[0072] When the first casting plate 301 and the second casting plate 302 containing the molten liquid are rotating following the receiving disc 2, the first casting plate 301 will drive the linkage frame 19 to move at the same time, and the linkage frame 19 will gradually contact the limit frame 20. Under the limitation of the limit frame 20, the linkage frame 19 will drive the slider 18 to move a certain distance, and at this time the next pair of the first casting plate 301 and the second casting plate 302 also just move to the side corresponding to the liquid outlet pipe fitting 401. At this time, the receiving disc 2 just stops rotating. At this time, the slider 18 has driven the first casting plate 301 away from the second casting plate 302, and the formed blade is exposed at this time, so as to facilitate the subsequent staff to take out the formed blade, and the operation is relatively convenient.

[0073] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
