Description

Technical Field

[0001] This invention belongs to the field of metal workpiece processing, specifically a rust prevention device for metal workpiece processing. Background Technology

[0002] Rust prevention in metal workpiece processing is an important step in ensuring the quality of finished products and extending their service life. There are many methods commonly used for metal sheet workpieces, among which spraying anti-corrosion paint is the most common.

[0003] In existing technologies, the application of anti-corrosion paint to metal sheet workpieces is mostly done by fixed machine spraying, resulting in a relatively fixed spraying area and poor spraying uniformity. This reduces the anti-rust treatment effect and durability of the workpiece. Furthermore, the workpiece is not effectively cleaned before painting, and the dust and impurities adhering to the workpiece surface will further affect the subsequent painting effect. Moreover, after painting, it is necessary to wait for the anti-corrosion paint to dry naturally, which prevents the anti-corrosion paint from solidifying and drying quickly, thereby increasing the risk of damage to the anti-corrosion coating.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-6 A rust prevention treatment device for metal workpiece processing includes a base 1, a movable platform 2 slidably connected to the top of the base 1, a clamping plate 3 symmetrically slidably connected to the top of the movable platform 2, a cleaning tank 4 symmetrically fixedly connected to one side of the top of the base 1, a support frame 5 fixedly connected to the side of the top of the base 1 near the cleaning tank 4, a first dryer 6 and a second dryer 30 respectively installed on the two sides inside the support frame 5, a cleaning cylinder 7 symmetrically provided on the bottom of the support frame 5 near the first dryer 6, a paint spraying box 8 symmetrically fixedly connected to the side of the top of the base 1 away from the cleaning tank 4, a rotating shaft 19 rotatably connected to the top of the base 1 and on both sides of the movable platform 2 via a second fixing plate 17, a spray rack 21 fixedly connected to the outside of the two rotating shafts 19 near the sides of the cleaning tank 4 and the paint spraying box 8 respectively, and a transmission component and an adjustment component respectively provided on the top of the base 1.

[0025] Specifically, the transmission assembly includes a first fixed plate 9 and a linkage unit. The first fixed plate 9 is fixedly connected to the top side of the base 1 and located between two rotating shafts 19. A transmission screw 10 is rotatably connected to the lower interior of the first fixed plate 9. The moving platform 2 is threadedly connected to the outside of the transmission screw 10. A first motor 11 is fixedly connected to the top of the base 1 near the first fixed plate 9 via a mounting block. The output end of the first motor 11 extends to one side of the first fixed plate 9 and is fixedly connected to the transmission screw 10. The spray frame 21 can swing through the linkage unit, which includes a first bevel gear 12, a second bevel gear 13, and a third bevel gear 14. A bevel gear 12 is fixedly connected to the outside of the output end of the first motor 11. A reciprocating screw 13 is rotatably connected to the outside of the first fixed plate 9 via a limiting plate. A second bevel gear 14 is fixedly connected to the bottom of the reciprocating screw 13. The first bevel gear 12 and the second bevel gear 14 are meshed together. A threaded block 15 is threadedly connected to the outside of the reciprocating screw 13. Connecting rods 16 are rotatably connected to both sides of the threaded block 15. A rack 18 is slidably connected to the outside of both second fixed plates 17 via limiting plates. The ends of the two connecting rods 16 away from the reciprocating screw 13 are rotatably connected to the corresponding racks 18. One end of each rotating shaft 19 extends to the outside of the second fixed plate 17 and is fixedly connected to a transmission gear 20. Each transmission gear 20 meshes with a corresponding rack 18. The adjustment assembly includes a first bidirectional lead screw 24 and an adjustment unit. The first bidirectional lead screw 24 is rotatably connected to the inside of the moving platform 2. A second motor 25 is fixedly connected to one side of the bottom of the moving platform 2 via a protective cover. The output end of the second motor 25 extends to the outside of the protective cover and is fixedly connected to the first bidirectional lead screw 24. The bottoms of the two clamping plates 3 extend to the bottom of the moving platform 2 via sliding plates and are threadedly connected to the first bidirectional lead screw 24. On the outer sides of the lever 24, the cleaning cylinders 7 can be moved by the adjustment unit, which includes a sliding plate 27. The sliding plate 27 is symmetrically slidably connected to the top of the support frame 5. The tops of the two cleaning cylinders 7 extend to the top of the support frame 5 and are rotatably connected to the bottom of the two sliding plates 27 respectively. The top side of the support frame 5 is rotatably connected to the second bidirectional screw 28 through a limiting block. The two sliding plates 27 are threaded to the outer sides of the second bidirectional screw 28 respectively. The top side of the support frame 5 is fixedly connected to the third motor 29 through a mounting block. The output end of the third motor 29 is fixedly connected to the second bidirectional screw 28.

[0026] The above technical solution requires that before rust prevention treatment of the metal plate workpiece, it should first be placed on top of the moving platform 2. Then, the second motor 25 is started by an external controller. The output of the second motor 25 drives the first bidirectional lead screw 24 to rotate, so that the first bidirectional lead screw 24 drives the clamping plates 3 on both sides to move towards the workpiece through the threaded connection until the corresponding limit rod 26 clamps the workpiece. This allows for adaptation according to the thickness of different workpieces. After the workpiece is installed and fixed, the first motor 11 is started by an external controller. The output of the first motor 11 drives the transmission lead screw 10 and the first bevel gear 12 to rotate, so that the first bevel gear 12 drives the moving platform 2 to move to one side through the threaded connection. When the moving platform 2 moves the workpiece to the desired position... When cleaning tank 4, the booster pumps inside both cleaning tanks 4 are activated, causing the booster pumps to draw cleaning water through hoses 22 into the corresponding spray racks 21 and spray it out, thus spraying and cleaning the surface of the workpiece. After cleaning, the workpiece continues to move towards the support frame 5. At this time, the booster pumps inside the cleaning tank 4 are turned off, and the first dryer 6 is turned on. The first dryer 6 blows hot air to dry the workpiece. Then, when the workpiece passes through the cleaning cylinder 7, the drive device inside the slide plate 27 drives the cleaning cylinder 7 to rotate, thus cleaning the surface of the workpiece through the cleaning cylinder 7, wiping away residual water stains, and brushing away stubborn stains on the surface of the workpiece, thereby effectively ensuring the cleanliness of the workpiece surface and improving the adhesion of the subsequent anti-rust paint. After the workpiece is dried... Afterwards, the workpiece continues to move towards the spray booth 8. At this time, the first dryer 6 is turned off and the booster pump in the spray booth 8 and the second dryer 30 are turned on. The booster pump in the spray booth 8 can draw the anti-rust paint through the hose 22 into the corresponding spray frame 21 and spray it out, thus performing the anti-rust paint spraying work on the workpiece. In addition, in this device, the first bevel gear 12 rotates while driving the second bevel gear 14 and the reciprocating screw 13 to rotate through the meshing relationship. The reciprocating screw 13 then drives the threaded block 15 to reciprocate through the threaded connection relationship. The threaded block 15 can drive the connecting rods 16 on both sides to drive the corresponding rack 18 to reciprocate, so that the rack 18 drives the transmission gear 20 and the rotating shaft 19 to reciprocate through the threaded connection relationship, thereby driving the rotating shaft 19 to reciprocate. The external spray frame 21 is driven to reciprocate, which expands the spraying range and improves the uniformity of the spraying, ensuring the cleaning and painting effect of the workpiece. After cleaning and rust-preventive paint spraying, the workpiece moves to the second dryer 30 for secondary drying. This allows for rapid solidification and drying of the rust-preventive paint on the workpiece surface, reducing damage to the anti-corrosion coating and effectively improving the production quality and rust-preventive life of the metal workpiece. After the secondary drying is completed, the workpiece can be removed. When processing workpieces of different thicknesses, the distance between the two cleaning cylinders 7 needs to be adjusted. The third motor 29 is started by an external controller, and the output of the third motor 29 drives the second bidirectional lead screw 28.The second bidirectional lead screw 28, through a threaded connection, drives the two sliding plates 27 on both sides to move closer to each other or in opposite directions. The two sliding plates 27 then drive the corresponding cleaning cylinders 7 to move synchronously until a suitable spacing is achieved. Turning off the third motor 29 completes the adjustment, facilitating the cleaning of workpieces of different thicknesses. This effectively improves the flexibility and adaptability of the device. Before applying anti-rust paint, the device can first spray the workpiece with cleaning water, then clean and initially dry it, effectively ensuring the cleanliness of the workpiece surface and improving the adhesion of the subsequent anti-rust paint. The device applies rust-preventive paint to the workpiece. During the cleaning and painting process, the rotating shaft 19 drives multiple spray frames 21 to reciprocate, expanding the spraying range and improving spray uniformity, ensuring effective cleaning and painting. After painting, a secondary drying process is performed to quickly solidify and dry the rust-preventive paint, minimizing damage to the anti-corrosion coating. This effectively improves the production quality and rust-prevention lifespan of the metal workpiece, thus significantly enhancing the rust prevention process and improving the processing quality and efficiency of the device.

[0027] Specifically, multiple spray racks 21 are all fixedly connected to the outside of hoses 22, and the other end of each hose 22 extends into the interior of the corresponding cleaning tank 4 and paint spraying tank 8 and is fixedly connected thereto. Each hose is also equipped with a booster pump. Each cleaning tank 4 and paint spraying tank 8 is fixedly connected to a filling port 23 on one side of its top.

[0028] Through the above technical solution, the cleaning water or anti-rust paint in the cleaning tank 4 and the paint spraying tank 8 can be replenished through the filling port 23.

[0029] Specifically, limit rods 26 are symmetrically fixedly connected to the inner sides of the two clamping plates 3, and anti-slip pads are fixedly connected to one end of each of the multiple limit rods 26. Drying heads 31 are fixedly connected to the bottom of the first dryer 6 and the second dryer 30 extending to the bottom of the support frame 5. The first motor 11, the second motor 25, and the third motor 29 are all electrically connected to an external controller.

[0030] The above technical solution effectively improves the stability of workpiece fixation by setting anti-slip pads, and allows workers to quickly control the first motor 11, the second motor 25, and the third motor 29 through an external controller.

[0031] Before applying rust prevention treatment to the metal plate workpiece, it is first placed on top of the moving platform 2. Then, the second motor 25 is started via an external controller. The output of the second motor 25 drives the first bidirectional lead screw 24 to rotate, causing the first bidirectional lead screw 24 to move the clamping plates 3 on both sides toward the workpiece through a threaded connection until the corresponding limit rod 26 clamps the workpiece. This allows for adaptation to different workpiece thicknesses. After the workpiece is installed and fixed, the first motor 11 is started via an external controller. The output of the first motor 11 drives the transmission lead screw 10 and the first bevel gear 12 to rotate, causing the first bevel gear 12 to move the moving platform 2 to one side through a threaded connection. When the moving platform 2 moves the workpiece to the cleaning tank... At point 4, the booster pumps inside the two cleaning tanks 4 are activated, drawing cleaning water through hoses 22 to the corresponding spray racks 21 and spraying it out to clean the workpiece surface. After cleaning, the workpiece continues to move towards the support frame 5. At this time, the booster pumps inside the cleaning tanks 4 are turned off, and the first dryer 6 is turned on. Hot air blown from the first dryer 6 dries the workpiece. Then, as the workpiece passes through the cleaning cylinder 7, the drive device inside the slide plate 27 rotates the cleaning cylinder 7, allowing it to clean the workpiece surface, removing residual water stains and stubborn dirt, effectively ensuring the cleanliness of the workpiece surface and improving the adhesion of the subsequent anti-rust paint. After the workpiece is dried... The workpiece continues to move towards the spray booth 8. At this time, the first dryer 6 is turned off and the booster pump in the spray booth 8 and the second dryer 30 are turned on. The booster pump in the spray booth 8 can draw the anti-rust paint through the hose 22 to the corresponding spray frame 21 and spray it out, thus performing the anti-rust paint spraying work on the workpiece. In this device, the first bevel gear 12 rotates while driving the second bevel gear 14 and the reciprocating screw 13 to rotate through the meshing relationship. The reciprocating screw 13 then drives the threaded block 15 to reciprocate through the threaded connection. The threaded block 15 can drive the connecting rods 16 on both sides to drive the corresponding rack 18 to reciprocate. This causes the rack 18 to drive the transmission gear 20 and the rotating shaft 19 to reciprocate through the threaded connection, thereby driving the rotating shaft 19 to... The external spray frame 21 reciprocates, which expands the spraying range and improves the uniformity of the spray, ensuring the cleaning and painting effect. After cleaning and rust-preventive paint coating, the workpiece moves to the second dryer 30 for secondary drying. This allows for rapid solidification and drying of the rust-preventive paint on the workpiece surface, reducing damage to the anti-corrosion coating and effectively improving the production quality and rust-preventive lifespan of the metal workpiece. Once the secondary drying is complete, the workpiece can be removed. When processing workpieces of different thicknesses, the distance between the two cleaning cylinders 7 needs to be adjusted. The third motor 29 is started via an external controller, and its output drives the second bidirectional lead screw 28.The second bidirectional lead screw 28, through a threaded connection, drives the two sliding plates 27 on both sides to move closer to each other or in opposite directions. The two sliding plates 27 then drive the corresponding cleaning cylinders 7 to move synchronously until the appropriate spacing is achieved. Turning off the third motor 29 completes the adjustment, facilitating the cleaning of workpieces of different thicknesses and effectively improving the flexibility and adaptability of the device. This device can first spray the workpiece with cleaning water before applying anti-rust paint, then clean and initially dry it, effectively ensuring the cleanliness of the workpiece surface and improving the adhesion of the subsequent anti-rust paint. Then, the anti-rust paint is applied. Furthermore, during the cleaning and spraying process, the device can drive multiple spray frames 21 to reciprocate via the rotating shaft 19. The oscillating motion expands the spraying range and improves spray uniformity, ensuring both cleaning and painting effectiveness. A secondary drying process is then performed after spraying, allowing for rapid solidification and drying of the anti-rust paint, minimizing damage to the anti-corrosion coating and effectively improving the production quality and rust-proofing lifespan of metal workpieces. This significantly enhances the rust prevention process and improves the processing quality and efficiency of the device. The filling port 23 replenishes the cleaning water or anti-rust paint in the cleaning tank 4 and paint tank 8. Anti-slip pads effectively improve the stability of the workpiece. An external controller allows for easy and quick control of the first motor 11, second motor 25, and third motor 29.
