Description

Technical Field

[0001] This invention relates to the field of steel component processing technology, specifically to an automated rust removal device for steel components and its usage method. Background Technology

[0002] After production, steel components come into contact with air and undergo an oxidation reaction with moisture in the air, forming oxides (rust) on their surface. To improve the service life of steel components, a layer of paint is usually sprayed onto their surface to isolate them from the air and improve their oxidation resistance. To improve the adhesion between the paint and the steel component surface, the oxides (rust) on the steel component surface need to be removed before painting to prevent problems such as blistering, cracking, and peeling of the paint. Therefore, this invention proposes an automated rust removal device and method for steel components to solve the above problems. Summary of the Invention

[0012] A method for using an automated rust removal device for steel components includes the following steps:

[0013] Step 1: Place the steel component into the steel component conveying mechanism on the rust removal device, and clamp and fix one end of the steel component through the steel component conveying mechanism;

[0014] Step 2: Start the rust removal device.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-4 As shown, this invention discloses an automated rust removal device for steel components, comprising an installation platform 1, an installation box 2 fixedly connected to the top of the installation platform 1, a steel component conveying mechanism fixedly connected to the top of the installation box 2, a rust removal and cleaning mechanism fixedly connected to the top of the installation box 2, and a dewatering and drying mechanism provided on the top of the installation box 2. The steel component is clamped by the steel component conveying mechanism and then fed into the rust removal and cleaning mechanism. The rust removal and cleaning mechanism thoroughly removes rust from the surface of the steel component and cleans its surface. After cleaning, the steel component is conveyed to the dewatering and drying mechanism, where the dewatering and drying mechanism removes and dries the water from the surface of the steel component. This achieves a streamlined rust removal process for steel components, and the rust-removed steel components are quickly dried and output to the spraying equipment. This avoids the problem of the sprayed coating bulging, cracking, and peeling due to rust on the surface of the steel component when it is sprayed with moisture, thus greatly improving the rust removal effect on the surface of the steel component.

[0028] The steel component conveying mechanism includes a mounting plate 11 fixedly connected to the mounting box 2. A threaded sleeve 12 is rotatably connected to the mounting plate 11. A threaded rod 13 is threadedly fitted onto the inner surface of the threaded sleeve 12. One end of the threaded rod 13 is fixedly connected to a mounting block 14. A mounting groove 15 is provided on one side of the mounting block 14. A transmission plate 16 is slidably connected within the mounting groove 15. A first electric telescopic rod 17 is fixedly connected to the bottom of the transmission plate 16. A clamping plate 18 is fixedly connected to the bottom end of the first electric telescopic rod 17. A second electric telescopic rod 19, fixedly connected to the mounting block 14, is fixedly connected to the top of the transmission plate 16 via a connecting block. A transmission mechanism connected to the mounting plate 11 is driven to the outer surface of the threaded sleeve 12. First, the first electric telescopic rods 17 on the upper and lower transmission plates 16 on the mounting block 14 drive the clamping plate 18 to clamp and fix the steel component. The two clamping plates 18 move through the second electric telescopic rod 19, causing the first electric telescopic rod 17 and the clamping plate 18 to move. Plate 18 enters the mounting groove 15, and simultaneously drives the threaded sleeve 12 to rotate forward and backward through the transmission mechanism. The threaded sleeve 12 drives the threaded rod 13 to rotate and move, thereby causing the steel component to move left and right and rotate forward and backward. At the same time, after cleaning the surface of the steel component, the upper and lower clamping plates 18 cannot clean the surface of the steel component because they clamp and block it. At this time, the second electric telescopic rods 19 on the front and rear transmission plates 16 drive the first electric telescopic rods 17 on the transmission plate 16 and the clamping plate 18 to move out of the mounting groove 15. Then, the first electric telescopic rods 17 drive the clamping plate 18 to clamp the steel component. Then, the upper and lower first electric telescopic rods 17 drive the clamping plate 18 to move and no longer clamp the steel component. At the same time, the second electric telescopic rods 19 on the upper and lower transmission plates 16 drive the transmission plate 16 to move, so that the clamping plate 18 moves into the mounting groove 15. Then, the steel component moves and rotates, realizing the cleaning of the previously blocked position, thereby achieving comprehensive rust removal cleaning of the surface of the steel component and greatly improving the rust removal effect of the steel component.

[0029] The transmission mechanism includes a motor 21 fixedly connected to the mounting plate 11. The output end of the motor 21 is fixedly connected to a rotating shaft 22 via a coupling. A first gear 23 is fixedly sleeved on the outer surface of the rotating shaft 22. A second gear 24 is meshed with the outer surface of the first gear 23 and fixedly sleeved on the threaded sleeve 12. The motor 21 is controlled by a PLC programming program, which can control the forward and reverse rotation and the rotation angle of the motor 21. The motor 21 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the threaded sleeve 12 to rotate via the first gear 23 and the second gear 24.

[0030] The rust removal and cleaning mechanism includes a first mounting frame 31 fixedly connected to the mounting box 2. A first pipe 32 is fixedly connected inside the first mounting frame 31. An annular spray ring 33 is fixedly connected to the bottom of the first pipe 32. Multiple spray heads 34 are fixedly connected to the inner surface of the annular spray ring 33. A first pump body 35 is fixedly connected to the outer surface of the first pipe 32 via a pipe. A rust removal liquid container 36 fixedly connected to the mounting platform 1 is fixedly connected to the input end of the first pump body 35 via a pipe. A second mounting frame 37 is fixedly connected to the top of the mounting box 2. A brush ring 38 is fixedly connected inside the second mounting frame 37. A brush 39 is fixedly connected to the inner surface of the brush ring 38. A rinsing device is provided on the top of the mounting box 2. The mechanism pumps rust-removing liquid into the first pipe 32 through the first pump body 35 and the pipe, and then into the annular spray ring 33 through the first pipe 32. The liquid is then sprayed out through the spray head 34 on the annular spray ring 33. At the same time, the steel component conveying mechanism drives the steel component to move and rotate, thereby achieving uniform spraying of rust-removing liquid on the surface of the steel component. Subsequently, the steel component conveying mechanism drives the steel component to move into the brushing ring 38. At the same time, the transmission mechanism drives the threaded sleeve 12 to rotate back and forth. The threaded sleeve 12 drives the threaded rod 13 and the steel component on the mounting block 14 to move back and forth left and right while rotating back and forth, thereby achieving that the brush 39 can fully brush away the rust and impurities on the surface of the steel component, improving the removal effect of rust and impurities on the surface of the steel component.

[0031] The rinsing mechanism includes a third mounting frame 41 fixedly connected to the mounting box 2. A second pipe 42 is fixedly connected inside the third mounting frame 41. An annular rinsing ring 43 is fixedly connected to the bottom end of the second pipe 42. Multiple rinsing heads 44 are fixedly connected to the inner surface of the annular rinsing ring 43. A second pump body 45 is fixedly connected to the outer surface of the second pipe 42 through a pipe. A clean water container 46 fixedly connected to the mounting platform 1 is fixedly connected to the input end of the second pump body 45 through a pipe. After being thoroughly cleaned by the brush 39, the steel component is then transported into the annular rinsing ring 43 by the steel component conveying mechanism. Then, cleaning water is pumped into the second pipe 42 through the second pump body 45 and the pipe, and enters the annular rinsing ring 43 through the second pipe 42. Finally, the rinsing heads 44 in the annular rinsing ring 43 thoroughly clean the rust and impurities on the surface of the annular steel component.

[0032] The dehydration and drying mechanism includes a fourth mounting frame 51 fixedly connected to the mounting box 2. A third pipe 52 is fixedly connected inside the fourth mounting frame 51. An annular water-absorbing ring 53 is fixedly connected to the bottom end of the third pipe 52. A water-absorbing sponge 54 is fixedly connected inside the annular water-absorbing ring 53. A water-absorbing pump 55, fixedly connected to the mounting platform 1, is fixedly connected to the outer surface of the third pipe 52 via a pipe. A fifth mounting frame 56 is fixedly connected to the top of the mounting box 2. A fourth pipe 57 is fixedly connected inside the fifth mounting frame 56. An annular hot air ring 58 is fixedly connected to the bottom end of the fourth pipe 57. Multiple heat exchangers are fixedly connected to the inner surface of the annular hot air ring 58. The outer surface of the fourth pipe 57 is fixedly connected to the first hot air blower 590, which is fixedly connected to the mounting platform 1. After cleaning, the steel component is transported into the annular water absorption ring 53 by the steel component conveying mechanism. Then, the water on the surface of the steel component is absorbed by the water-absorbing sponge 54 in the annular water absorption ring 53. At the same time, the excess water on the water-absorbing sponge 54 is sucked out by the water-absorbing pump 55, the pipe and the third pipe 52. Then, it is introduced into the annular hot air ring 58. Then, the first hot air blower 590, the pipe and the third pipe 52 supply hot air to the annular hot air ring 58. The hot air is blown out by the hot air blower 59 to dry the surface of the annular steel component.

[0033] The fifth mounting bracket 56 is fixedly connected to a second hot air blower 61. The input end of the second hot air blower 61 is fixedly connected to a suction ring 62 through a pipe. Multiple suction heads 63 are fixedly connected to the outer surface of the suction ring 62. The output end of the second hot air blower 61 is fixedly connected to a blowing ring 64 through a pipe. Multiple drying heads 65 are fixedly connected to the inner surface of the blowing ring 64. The hot air lost during the drying process of the annular hot air ring 58 is drawn into the second hot air blower 61 for heating through the second hot air blower 61, the pipe suction ring 62, and the suction heads 63. Then, it is supplied into the blowing ring 64 through the pipe. Subsequently, the surface of the water-absorbing sponge 54 is dried through the drying heads 65 on the blowing ring 64, thereby further improving the water absorption of the water-absorbing sponge 54, allowing the water-absorbing sponge 54 to better absorb water from the surface of the steel component. At the same time, the heat lost during the drying process is effectively utilized, realizing heat recovery and achieving energy saving and environmental protection of the equipment.

[0034] A method for using an automated rust removal device for steel components includes the following steps:

[0035] Step 1: Place the steel component into the steel component conveying mechanism on the rust removal device, and clamp and fix one end of the steel component through the steel component conveying mechanism;

[0036] Step 2: Start the rust removal device. The steel component conveying mechanism transports the steel components, and then, in coordination with the rust removal cleaning mechanism and the water removal drying mechanism on the rust removal device, the rust stains on the surface of the steel components are thoroughly removed.

[0037] Step 3: Remove the rust-removed steel components from the steel component conveying mechanism to obtain clean steel components.

[0038] The working principle of this invention is as follows: First, the first electric telescopic rod 17 on the upper and lower transmission plates 16 of the mounting block 14 drives the clamping plate 18 to clamp and fix the steel component. The two clamping plates 18 move through the second electric telescopic rod 19, causing the transmission plates 16 to move, so that the first electric telescopic rod 17 and the clamping plate 18 enter the mounting groove 15. At the same time, the threaded sleeve 12 is driven to rotate forward and backward through the transmission mechanism. The threaded sleeve 12 drives the threaded rod 13 to rotate and move, thereby causing the steel component to move left and right and rotate forward and backward. At the same time, when the surface of the steel component is cleaned, it cannot be cleaned because the upper and lower clamping plates 18 clamp and block the surface of the steel component. At this time, the two clamping plates 18 move through the second electric telescopic rod 19 to clamp and fix the steel component. The second electric telescopic rods 19 on the two transmission plates 16 drive the first electric telescopic rods 17 and clamping plates 18 on the transmission plates 16 to move out of the mounting slots 15. Then, the first electric telescopic rods 17 drive the clamping plates 18 to clamp the steel component. Subsequently, the two first electric telescopic rods 17 move the clamping plates 18 to stop clamping the steel component. At the same time, the second electric telescopic rods 19 on the two transmission plates 16 drive the transmission plates 16 to move, so that the clamping plates 18 move into the mounting slots 15. Then, the steel component moves and rotates, so as to clean the blocked area, thereby achieving a comprehensive rust removal cleaning of the surface of the steel component and greatly improving the rust removal effect of the steel component.

[0039] After being thoroughly cleaned by the brush 39, the steel component is then transported to the annular flushing ring 43 via the steel component conveying mechanism. Cleaning water is then pumped into the second pipe 42 via the second pump body 45 and the pipe, and enters the annular flushing ring 43 through the second pipe 42. The flushing head 44 within the annular flushing ring 43 thoroughly cleans away rust and impurities from the surface of the annular steel component. After cleaning, the steel component is transported to the annular water absorption ring 53 via the steel component conveying mechanism. The water-absorbing sponge 54 within the annular water absorption ring 53 absorbs the water from the surface of the steel component. Simultaneously, the water pump 55, the pipe, and the third pipe 52 remove excess water from the water-absorbing sponge 54, which is then introduced into the annular hot air ring 58. Hot air is then supplied to the annular hot air ring 58 via the first hot air blower 590, the pipe, and the third pipe 52. The hot air is blown out through the hot air blower head 59 to dry the surface of the annular steel component.
