Description

Technical Field

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

[0002] As a key component of the engine, the turbine blades are located in the most demanding part of the engine environment. They play an extremely critical role in aircraft or gas turbines. They need to withstand high temperatures and high centrifugal loads when working. To improve the performance of the engine, increasing the front inlet temperature is a key indicator. Turbine blades need to be cast during production.

[0003] For example, the application publication number CN117259685A discloses a blade positioning reference casting mold, which is used to prepare a positioning reference on the periphery of the blade of an aircraft engine. 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 arranged 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 periphery of the blade for convenient clamping and positioning, and the blade is clamped and positioned using the positioning reference, which simplifies the clamping process and improves the clamping efficiency and clamping accuracy.

[0004] Although the above technical solution improves the clamping efficiency, there are still other problems in its specific use. For example, when casting, molten liquid needs to be introduced into the casting cavity, that is, the discharge pipe and the feed pipe need to be completely connected, so as to prevent the molten liquid from falling to other positions of the casting table. However, it is more troublesome to connect the two pipe bodies.

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

When one of the placement plates 3 moves to correspond to the liquid outlet pipe 401, under the action of the docking assembly, the liquid outlet pipe 401 at the bottom of the liquid storage chamber seat 4 will move toward the side of the merged docking tube 5, and then the molten liquid inside the liquid storage chamber seat 4 will enter the docking tube 5 from the inside of the liquid outlet pipe 401, and then pass into the cavity between casting plate 1 301 and casting plate 2 302, and then control the liquid outlet pipe 401 of the docking assembly to move away from the docking tube 5, and under the continued rotation of the receiving disc 2, the casting plate 1 301 and casting plate 2 302 containing the molten liquid will continue to rotate.

[0026] like Figures 3 to 7 As shown, the trigger unit includes: a sliding plate 8, the sliding plate 8 is slidably arranged on the upper end surface of the placement plate 3, the casting plate 1 301 and the casting plate 2 302 are arranged above the sliding plate 8; a contact 3 9, the contact 3 9 is fixedly installed on the lower end surface of the sliding plate 8; a contact 4 10, the contact 4 10 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 rod 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; During operation, in the initial state, that is, the molten liquid has not yet been introduced into the casting plate 1 301 and the casting plate 2 302, that is, the contact point 3 9 and the contact point 4 10 are not in contact; after the liquid outlet pipe 401 and the docking pipe 5 are docked, as the molten liquid in the cavity between the casting plate 1 301 and the casting plate 2 302 increases, the gravity of the casting plate 1 301 and the casting plate 2 302 and the sliding plate 8 gradually exceeds the supporting force of all the elastic telescopic rods 11, so the sliding plate 8 will move downward, and as the casting plate 1 301 and After the molten liquid inside the casting plate 2 302 is completed, the sliding plate 8 also drives the contact 3 9 to move to the side of the contact 4 10 on the upper end surface of the placement plate 3. At this time, the contact 3 9 and the contact 4 10 are in contact, and the external circuit is connected. The external controller will first control the liquid outlet pipe 401 to move away from the docking pipe 5, and then control the receiving disc 2 to continue rotating, and make the casting plate 1 301 and the casting plate 2 302 where the molten liquid has been passed rotate to the other side, so as to facilitate the subsequent molding of the turbine blades and their removal.

[0027] The upper end surface of the placement plate 3 is provided with a limiting groove adapted to the elastic telescopic rod 11, and the outer peripheral surface of the elastic telescopic rod 11 is sleeved with a telescopic spring 12; when working, the limiting groove is provided, which can facilitate the sliding plate 8 to press down the elastic telescopic rod 11, and make the subsequent contact three 9 and contact four 10 contact, and under the action of the telescopic spring 12, the sliding plate 8 can be easily supported.

[0028] The docking assembly further includes: a fixing plate 13, the fixing plate 13 is fixedly mounted on the lower side of the liquid storage chamber seat 4; an L-shaped electric telescopic rod 14, the L-shaped electric telescopic rod 14 is fixedly mounted 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 401; During operation, when the contact 1 6 and the contact 2 7 are in contact, that is, the external circuit is connected, and the two corresponding butt joints 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 401 to move toward the side of the butt joints 5 that are closed together, so that the molten liquid can be easily introduced into the casting plate 1 301 and the casting plate 2 302; as the weight of the sliding plate 8, the casting plate 1 301 and the casting plate 2 302 gradually increases, the sliding plate When 8 moves downward, contact 2 7 on the side wall of casting plate 2 302 will gradually separate from contact 1 6, and gradually contact 3 9 will contact contact 4 10. When the latter two are in contact, the external circuit is connected, and the L-shaped electric telescopic rod 14 will be controlled to drive the liquid outlet pipe 401 to move upward, so that the liquid outlet pipe 401 gradually moves away from the docking pipe 5. Then the controller will control the receiving disc 2 to rotate, so that it is convenient for the subsequent casting plate 1 301 and casting plate 2 302 to continue casting the turbine blades.

[0029] like Figures 3 to 9 As shown, the liquid outlet pipe fitting 401 includes: a contact tube 15, the contact tube 15 is slidably arranged on the inner wall of the liquid outlet pipe fitting 401, and a sealing member is arranged at the contact position between the contact tube 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 tube 15; a folding sealing plate 16, two folding sealing plates 16 are designed, and are symmetrically rotated and designed on the inner wall of the liquid outlet pipe fitting 401, and the two folding sealing plates 16 will completely seal the inner wall of the liquid outlet pipe fitting 401 when combined; a pull rod 17, one end of the pull rod 17 is ball-connected to the side wall of the folding sealing plate 16, and the other end is ball-connected to the inner wall of the contact tube 15; During operation, in the initial state, that is, when the liquid outlet pipe fitting 401 has not yet contacted the docking pipe 5, the two folding sealing plates 16 are closed together and will block the liquid outlet pipe fitting 401, so that the molten liquid inside the liquid storage chamber seat 4 will not flow out from 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 tube 15 to move downward, the contact tube 15 will simultaneously drive the pull rod 17 to move, and when the bottom end of the contact tube 15 extends into the docking pipe 5, the two folding sealing plates 16 are also pulled open, and at this time, the molten liquid above the liquid outlet pipe fitting 401 will enter the casting plate 1 301 and the casting plate 2 302 along the docking pipe 5, thereby realizing the casting of the turbine blades.

[0030] The casting plate 2 302 is slidably arranged above the sliding plate 8, and a pushing unit is arranged above the sliding plate 8, and the pushing unit is used to control the casting plate 2 302 to move away from the casting plate 1 301; during operation, when the molten liquid of the turbine blades is gradually formed inside the casting plates 1 301 and 302, and as the receiving disc 2 rotates, the pushing unit will drive the casting plate 2 302 to move away from the casting plate 1 301, and then it is convenient to take out the formed turbine blades.

[0031] The push-off 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 301, and a linkage frame 19 is installed at the end of the slider 18. A limit frame 20 is rotatably arranged at a position corresponding to the side wall of the workbench 1 and the linkage frame 19. When the linkage frame 19 rotates following the receiving disc 2, the end of the linkage frame 19 will contact the end of the limit frame 20. During operation, when the casting plate 1 301 and the casting plate 2 302 containing the molten liquid follow the rotation of the receiving disc 2, the casting plate 1 301 will simultaneously drive the linkage frame 19 to move, and the linkage frame 19 will gradually contact the limit frame 20. Under the limit of the limit frame 20, the linkage frame 19 will drive the slider 18 to move a certain distance. At this time, the next pair of casting plates 1 301 and the casting plate 2 302 also happen to move to the side corresponding to the liquid outlet pipe 401. At this time, the receiving disc 2 also happens to stop rotating. At this time, the slider 18 has driven the casting plate 1 301 away from the casting plate 2 302, and the formed blades are exposed at this time, so it is convenient for subsequent staff to take out the formed blades, and the operation is more convenient.

[0032] Limiting columns 21 are installed at the positions corresponding to the side walls of the workbench 1 and the limiting frames 20, and the upper end surface of the sliding plate 8 is provided with a sliding groove adapted to the slider 18; during operation, when the limiting frame 20 and the linkage frame 19 are in contact, under the pressure of the linkage frame 19, the limiting frame 20 will rotate in the direction away from the side of the linkage frame 19, and under the limitation of the limiting columns 21, the rotation position of the limiting frame 20 can be limited, which can facilitate the subsequent linkage frame 19 to detach from the limiting frame 20, and is conducive to the removal of the molded blades inside the subsequent casting plate 1 301 and the casting plate 2 302.

[0033] The side wall of the slider 18 is installed with a telescopic column 22, the outer surface of the telescopic column 22 is sleeved with a spring, and the end of the telescopic column 22 is connected to the side wall of the sliding plate 8; when working, when the slider 18 moves, it will compress the telescopic column 22 and the spring of the side wall at the same time, and under the pressure of the limit column 21, it can give the staff enough time to take out the formed blades, and at the same time, after the linkage frame 19 is separated from the limit frame 20, it is convenient for the slider 18 to drive the casting plate 301 to restore its initial position.

[0034] Working principle: in the initial state, the docking tube 5 on the upper end surface of the casting plate 1 301 is in contact with the docking tube 5 on the upper end surface of the casting plate 2 302, and then the receiving disc 2 is driven to rotate by controlling the output end of the external motor, so that the receiving disc 2 drives one of the placement plates 3 above it to move toward the side close to the liquid storage chamber seat 4. When one of the placement plates 3 moves to correspond to the liquid outlet pipe 401, at this time, under the action of the docking assembly, the liquid outlet pipe 401 at the bottom of the liquid storage chamber seat 4 will move toward the side of the merged docking tube 5, and then the molten liquid inside the liquid storage chamber seat 4 will enter the docking tube 5 from the inside of the liquid outlet pipe 401, and then pass into the cavity between the casting plate 1 301 and the casting plate 2 302, and then the liquid outlet pipe 401 of the docking assembly is controlled to move away from the docking tube 5, and under the continued rotation of the receiving disc 2, the casting plate 1 301 and the casting plate containing the molten liquid are connected. 201 and 202 will continue to rotate; when one pair of casting plates 1 301 and 2 302 follows the rotation of the receiving disc 2, that is, moves toward the side close to the liquid storage chamber seat 4, until the liquid outlet pipe 401 and the docking pipe 5 are aligned, at this time, the contact 2 7 on the side wall of the casting plate 2 302 will contact the contact 1 6 on the side wall of the liquid storage chamber seat 4, and the external circuit is connected, so that the external controller will control the liquid outlet pipe 401 at the bottom of the liquid storage chamber seat 4 to move toward the side close to the docking pipe 5, so that the liquid outlet pipe 401 and the docking pipe 5 can be automatically docked, and the problem of the molten liquid spilling to the outside of the workbench 1 can be avoided; 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 401 will move away from the docking pipe 5, thereby facilitating the continued casting of the remaining casting plates 1 301 and 2 302; In the initial state, the molten liquid has not yet been introduced into the casting plate 1 301 and the casting plate 2 302, that is, the contact point 3 9 and the contact point 4 10 are not in contact; after the liquid outlet pipe 401 and the butt pipe 5 are connected, as the molten liquid in the cavity between the casting plate 1 301 and the casting plate 2 302 increases, the gravity of the casting plate 1 301 and the casting plate 2 302 and the sliding plate 8 gradually exceeds the supporting force of all the elastic telescopic rods 11, so the sliding plate 8 will move downward, and as the casting plate 1 301 and the casting plate 2 302 are connected, the sliding plate 8 will move downward. After the molten liquid inside the second plate 302 is introduced, the sliding plate 8 just drives the contact point 3 9 to move to the side of the contact point 4 10 on the upper end surface of the placement plate 3. At this time, the contact point 3 9 and the contact point 4 10 are in contact, and the external circuit is connected. The external controller first controls the liquid outlet pipe 401 to move away from the docking pipe 5, and then controls the receiving disc 2 to continue rotating, so that the casting plate 1 301 and the casting plate 2 302, which have been introduced with the molten liquid, rotate to the other side, so as to facilitate the subsequent molding of the turbine blades and their removal; When the contact 1 6 and the contact 2 7 are in contact, that is, when the external circuit is connected, and the two corresponding butt joints 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 401 to move toward the side of the butt joint 5 that is closed together, so that it is convenient for the molten liquid to pass into the casting plate 1 301 and the casting plate 2 302; as the weight of the sliding plate 8, the casting plate 1 301 and the casting plate 2 302 gradually increases, when the sliding plate 8 moves downward, the contact 2 7 on the side wall of the casting plate 2 302 will gradually separate from the contact 1 6, and gradually the contact 3 9 will contact the contact 4 10. When the latter two are in contact, the external circuit is connected at this time, and the L-shaped electric telescopic rod 14 will be controlled to drive the liquid outlet pipe 401 to move upward, so that the liquid outlet pipe 401 gradually moves away from the butt joint 5, and then the controller will control the receiving disc 2 to rotate, so that it is convenient for the subsequent casting plate 1 301 and the casting plate 2 302 to continue casting the turbine blades; In the initial state, that is, when the liquid outlet pipe 401 has not yet contacted the docking pipe 5, the two folding sealing plates 16 are closed together and block the liquid outlet pipe 401, so that the molten liquid inside the liquid storage chamber seat 4 will not flow out from the liquid outlet pipe 401; when the liquid outlet pipe 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 simultaneously drive the pull rod 17 to move, and when the bottom end of the contact pipe 15 extends into the docking pipe 5, the two folding sealing plates 16 are also pulled open, and the molten liquid above the liquid outlet pipe 401 will enter the casting plate 1 301 and the casting plate 2 302 along the docking pipe 5 to achieve the casting of the turbine blades; When the casting plate 1 301 and the casting plate 2 302 containing the molten liquid follow the rotation of the receiving disc 2, the casting plate 1 301 will simultaneously drive the linkage frame 19 to move, and the linkage frame 19 will gradually contact the limit frame 20. Under the limit of the limit frame 20, the linkage frame 19 will drive the slider 18 to move a certain distance. At this time, the next pair of casting plates 1 301 and the casting plate 2 302 also happen to move to the side corresponding to the liquid outlet pipe 401. At this time, the receiving disc 2 also happens to stop rotating.
