Description

Technical Field

[0002] With the rapid development of aircraft engines, manufacturing high thrust-to-weight ratio and high-efficiency engines has always been an important aspect of competition among countries. Reducing the gap between the rotor and stator of aircraft engines is undoubtedly an important means to improve the thrust-to-weight ratio and utilization efficiency of aircraft engines. As the design gap between the rotor and stator decreases, the frequency of friction in aircraft engines increases greatly. At this time, it is particularly important to design and prepare an aircraft blade sealing tooth coating material with good friction and wear performance.

[0003] Cobalt-based super-temperature materials are gradually being used in the sealing tooth coatings of aircraft engine blades. They are mainly composed of superalloys such as cobalt, chromium, and molybdenum. They have excellent high-temperature tolerance and wear resistance, greatly improving the service life of aircraft blades. The blade sealing tooth coating needs to be welded to the blade sealing tooth by a welding wire made of new cobalt-based super-temperature materials using a combination of fusion welding. The current preparation process of cobalt-based welding wire is to prepare the master alloy rod through vacuum induction melting, and then prepare the welding wire through wire cutting and grinding. This preparation process has low production efficiency and high cost, is difficult to mass produce, and cannot meet existing welding needs. Summary of the Invention

The top of the positioning tube 11 is fixedly installed with a second spring 31. The end of the second spring 31 away from the positioning tube 11 is fixedly installed with a collar 32. The collar 32 is slidably installed on the outside of the slide tube 12, so that the mounting column 16 can contact the collar 32 when it moves downward, and the second spring 31 is used to release the second spring 31. The bottom of the collar 32 is fixed with multiple centrally symmetrically distributed inserts 33. The outer side of the positioning tube 11 is provided with slots for the inserts 33 to limit the insertion, preventing the collar 32 from tilting during movement. Multiple centrally symmetrically distributed support rods 34 are fixedly installed between the top plate 23 and the mounting cover 10. The outer side of the movable plate 19 is provided with a wing plate that slides on the outer side of the support rods 34, allowing the movable plate 19 to perform stable vertical movement.

A metal piston 28 is fixedly mounted on the end of the moving rod 27 away from the rotating block 26. The outer diameter of the metal piston 28 is the same as the inner diameter of the drainage pipe 24. The diameter corresponds to that of the liquid discharge pipe 24. When the moving rod 27 moves, the metal piston 28 can be pulled out from the top of the liquid discharge pipe 24, so that the molten steel in the pouring cup 5 enters the liquid discharge pipe 24, which is convenient for discharging the excess molten steel in the pouring cup 5. When the moving rod 27 moves downward, the molten steel in the liquid discharge pipe 24 can be pushed downward by the metal piston 28. A positioning sleeve 29 is fixedly installed at the bottom of the mounting cover 10.

The outer side of the moving rod 27 is provided with a spiral groove that cooperates with the spiral strip 30, so that when the moving rod 27 moves downward, the spiral groove on the outer side can move along the outer side of the spiral strip 30, so that the moving rod 27 is in a rotating state when moving, and the moving rod 27 can drive the metal piston 28 to rotate, so that the metal piston 28 can smoothly push the molten steel in the discharge pipe 24. A second positioning plate 35 is fixedly installed on the inner side of the furnace body 1, and the bottom end of the corundum tube 3 is fixedly installed on the inner side of the second positioning plate 35, and the bottom of the second positioning plate 35 is in contact with the top of the sealing disk 8.

A drain cylinder 37 is fixedly installed at the bottom end of the drain pipe 24, and the inner diameter of the drain cylinder 37 is larger than the inner diameter of the drain pipe 24, so that the metal piston 28 can push the molten steel in the drain pipe 24 into the drain cylinder 37 to prevent the residual molten steel in the drain pipe 24.

[0034] Working principle: First, the staff connects the pipeline for conveying molten steel with the injection valve 2, and opens the injection valve 2 to allow the molten steel to enter the pouring cup 5. Under the heating and insulation of the pouring cup 5 by the ring heater 6, the molten steel enters the corundum tube 3, and the molten steel can solidify into welding wire in the corundum tube 3. Then, the staff starts the electric telescopic rod 18, and the electric telescopic rod 18 pulls the movable plate 19 to move upward, so that the movable plate 19 drives the sleeve 25 to move, and the sleeve 25 drives the movable rod 27 to move synchronously through the rotating block 26. The movable rod 27 drives the metal piston 28 away from the top of the discharge pipe 24, so that the metal piston 28 opens the top of the discharge pipe 24, and the excess molten steel in the pouring cup 5 can enter the discharge pipe 24. At this time, the movable plate 19 and the bottom of the top plate 23 are The rod 21 moves along the inclined surface of the push block 22, and the rod 21 pushes the elastic card strip 20 to move through the push block 22, so that the elastic card strip 20 is away from the positioning circular table 17. The weight of the knocking block 14 is used to pull the sliding tube 12 downward along the inner side of the positioning tube 11 through the first spring 15. The knocking block 14 can contact the top of the welding wire inside the corundum tube 3, and use the elasticity of the first spring 15 to make the knocking block 14 elastically knock on the top of the welding wire. The knocking block 14 elastically knocks on the welding wire, and then the electric telescopic rod 18 drives the movable plate 19 to move downward, and the rod 21 can be away from the elastic card strip 20, and the jack of the movable plate 19 is sleeved on the positioning circular table 17. On the outside of the platform 17, the top of the positioning circular platform 17 can move along the inclined surface of the elastic card strip 20, so that the elastic card strip 20 moves along the inner side of the movable plate 19, and when the positioning circular platform 17 moves to the top of the elastic card strip 20, the elastic card strip 20 is used to make the elastic card strip 20 abut against the bottom of the positioning circular platform 17, and then, the electric telescopic rod 18 pulls the movable plate 19 upward again, so that the movable plate 19 pulls the positioning circular platform 17 upward through the elastic card strip 20, and the positioning circular platform 17 can drive the slide tube 12 to move through the mounting column 16, lift the knocking block 14, and when the insertion rod 21 is inserted into the slot of the elastic card strip 20 again, the knocking block 14 can knock the welding wire in the corundum tube 3 downward again, thereby, as the electric telescopic rod 18 moves, the welding wire in the corundum tube 3 is lifted. By reciprocating movement, the knocking block 14 can repeatedly elastically knock the top end of the welding wire, so that the welding wire moves downward along the inner side of the corundum tube 3, and when the moving rod 27 moves downward, the spiral groove on the moving rod 27 can move along the outer side of the spiral bar 30, so that the moving rod 27 is in a rotating state when moving, and the moving rod 27 drives the metal piston 28 to rotate synchronously, so that the metal piston 28 can smoothly push the molten steel in the drain pipe 24, prevent the drain pipe 24 from being blocked, and realize the clearing of the drain pipe 24. Finally, the staff takes out the welding wire detached from the corundum tube 3 and completes the preparation of the welding wire, which greatly improves the material utilization rate, reduces the welding wire preparation cost, and facilitates modular production, thereby achieving the effect of improving the production efficiency of the welding wire.
