Description

Technical Field

[0001] This utility model relates to the technical field of drying devices, specifically a drying device for the coating layer of centrifugal casting of cylinder liners. Background Technology

[0002] Centrifugal casting is a technique and method in which molten metal is injected into a high-speed rotating mold, allowing the molten metal to fill the mold and form a casting under the action of centrifugal force. During centrifugal casting, due to the high-speed rotation of the mold, the molten metal is subjected to a strong centrifugal force, which enables the molten metal to adhere tightly to the inner wall of the mold and be evenly distributed.

[0003] When drying centrifugally cast castings, the castings are usually placed in a drying oven and dried with hot air. This method cannot expose the castings to the hot air from all angles, so the hot air cannot fully contact and remove the moisture from the surface of the castings, thus affecting the drying efficiency. In addition, the hot air is blown unevenly, which may cause the castings to deform and crack during the drying process, thus affecting the drying quality. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for the coating layer of centrifugal casting of cylinder liners, so as to solve the problems mentioned in the background art.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses hot air to enter the lifting pipe through the air inlet pipe and dry the castings on the upper part of the placement tray through the air outlet. The first motor drives the power gear, which drives the placement tray to rotate through the gear ring and connecting plate, so that the castings are dried more evenly. The second motor drives the eccentric disk, which pushes the lifting pipe downward through the connecting plate. The lifting pipe moves downward due to gravity, thereby realizing the up and down movement of the lifting pipe and changing the position of the air outlet. This prevents some parts of the casting from not being effectively dried and can evenly dry all parts of the casting surface, improving drying efficiency and drying quality.

[0013] 2. This utility model also uses a rotating cap to rotate a set of upper bevel gears, which in turn rotates the lower bevel gears to rotate the other three sets of upper bevel gears. The rotation of the four sets of threaded rods drives the moving block to move, and the connecting rod drives the fixing plate and contact plate to fix the casting. This can effectively fix castings of different sizes. Attached Figure Description

[0021] The lower part of the lifting pipe 9 penetrates the drying box 1 and is fixedly welded with a connecting piece 10. A second mounting bracket 11 is fixedly welded to the lower part of one side of the drying box 1. A second motor 12 is mounted on the outer flange of the second mounting bracket 11. The power end of the second motor 12 penetrates the second mounting bracket 11 and is connected to an eccentric disc 13 via a coupling. The eccentric disc 13 is directly opposite the lower part of the connecting piece 10. The second motor 12 drives the eccentric disc 13, thereby pushing the lifting pipe 9 downward through the connecting piece 10. The lifting pipe 9 moves downward due to gravity, thus realizing the up and down movement of the lifting pipe 9. This causes the position of the air outlet 15 to change, preventing parts of the casting from not being effectively dried; a first spring 14 is fixedly welded between the connecting piece 10 and the drying box 1. The first spring 14 is sleeved on the outside of the lifting pipe 9. The first spring 14 pushes the connecting piece 10, thereby increasing the up-and-down vibration of the lifting pipe 9; a lower bevel gear 16 is rotatably installed in the middle of the inner side of the placement plate 2. Four sets of upper bevel gears 17 are meshed on the upper part of the lower bevel gear 16. A threaded rod 18 is fixedly welded to the tail of the upper bevel gear 17, and the tail of the threaded rod 18 penetrates through... A rotating cap 20 is fixedly welded to the placement plate 2. A movable block 19 is threadedly connected to the outer side of the threaded rod 18. Four sets of connecting grooves 22 are opened on the upper part of the placement plate 2, directly opposite the threaded rod 18. A connecting rod 21 is fixedly welded to the upper part of the movable block 19. The connecting rod 21 penetrates the connecting groove 22 and is fixedly welded to a fixing plate 23. By rotating the rotating cap 20, one set of upper bevel gears 17 rotates, which in turn causes the other three sets of upper bevel gears 17 to rotate through the lower bevel gear 16. The rotation of the four sets of threaded rods 18 drives the movable block 19 to move, which in turn drives the connecting rod 21 to move the movable block 19. The fixing plate 23 fixes the casting; a damping rod 24 is threaded on one side of the fixing plate 23, and a contact plate 26 is threaded on the other end of the damping rod 24. A second spring 25 is fixedly welded between the contact plate 26 and the fixing plate 23. The second spring 25 is sleeved on the outside of the damping rod 24. When the fixing plate 23 moves, the casting is fixed by the damping rod 24. When the casting is blown by hot air, the second spring 25 and the damping rod 24 are compressed and stretched to prevent the casting from vibrating excessively. The front rotating shaft of the drying oven 1 is connected to the oven door 27.

[0022] Working principle: In use, the casting is placed on the placement plate 2. By rotating the rotating cap 20, one set of upper bevel gears 17 rotates, which in turn causes three more sets of upper bevel gears 17 to rotate via the lower bevel gear 16. The four sets of threaded rods 18 rotate, driving the moving block 19 to move. The connecting rod 21 drives the fixing plate 23 and the contact plate 26 to fix the casting. Hot air enters the lifting pipe 9 through the air inlet pipe 8 and dries the casting on the upper part of the placement plate 2 through the air outlet 15. The first motor 6 drives the power gear 7, which in turn drives the gear ring 4 and the connecting plate 3 to... The rotating plate 2 makes the casting dry more evenly. The second motor 12 drives the eccentric plate 13, which pushes the lifting tube 9 downward through the connecting plate 10. The lifting tube 9 moves downward due to gravity, thus realizing the up and down movement of the lifting tube 9. The first spring 14 pushes the connecting plate 10, thereby increasing the up and down vibration of the lifting tube 9, causing the position of the air outlet 15 to change, preventing some parts of the casting from not being effectively dried. When the casting is blown by hot air, the second spring 25 and the damping rod 24 are compressed and stretched to prevent the casting from vibrating excessively.
