Description

Technical Field

[0001] This invention belongs to the field of surface rust removal, specifically relating to a surface rust removal device for metal product processing. Background Technology

[0002] During long-term storage or use, metal workpieces will develop rust due to oxidation. Rust affects the appearance and reduces the performance and lifespan of the metal, so rusted workpieces need to be re-polished and rust-removed before use.

[0003] Currently, most rust removal methods are laser rust removal and mechanical rust removal. In terms of mechanical rust removal, long strips of rusty workpieces may not only rust during long-term storage, but improper storage may also cause them to bend. Some existing grinding methods may not be able to grind them properly due to their bending, requiring subsequent manual re-grinding. Furthermore, excessively bent workpieces may even cause damage to the grinding equipment if not handled carefully. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the relative compression of the clamping plates, can correct the bending position when the workpiece enters the grinding area, so that it does not affect the grinding effect in subsequent grinding. When grinding slightly bent workpieces, the inner wall of the bend may not be touched by the grinding equipment and thus cannot be ground, while the protruding part may be over-ground, resulting in uneven rust removal effect. When the workpiece is too bent, the bending area may not be able to pass through the machine's conveyor when the workpiece enters the grinding equipment, and forced conveying may damage the machine. By flipping the flip plate, the transmission can be triggered to open after the overbent workpiece enters, so that the workpiece falls off the platform and does not enter the grinding stage, thus protecting the machine equipment.

[0013] 2. This invention addresses the issue that after the workpiece is polished and output, if it is not used immediately, the cleaned metal surface will oxidize when exposed to air. However, through a linked device, an oiling cloth containing rust-preventive oil is used to wipe and coat the workpiece. The device's drive causes the oiling cloth to rotate slowly, forming a protective film on the metal surface to prevent secondary rusting and avoiding localized wear caused by continuous friction in the same area. This extends the lifespan of the oiling cloth. Furthermore, during rotation, a press-type valve allows for intermittent addition of rust-preventive oil to the cloth, eliminating the need for manual application and reducing maintenance time. Manual application can easily result in adding too much or too little rust-preventive oil, or even forgetting to add it. Too much oil can contaminate the equipment and cause waste, while too little oil will prevent the cloth from completely coating the workpiece.

[0014] 3. In this invention, after the workpiece is polished and coated with rust-preventive oil, it is pushed to one side of the storage rack by a rotating plate via a transmission mechanism. The rotating mechanism is triggered when each workpiece enters, allowing the workpieces coated with rust-preventive oil to be stored on the rack for a period of time. This allows the rust-preventive oil to fully penetrate and dry, forming a stable oil film that better protects the workpiece. In contrast, if workpieces are placed randomly after applying rust-preventive oil, they may come into contact with each other and rub against each other, damaging the oil film before it has stabilized. At the same time, the feeding speed is controlled by a designed delay mechanism to ensure that each workpiece has enough time to allow the rust-preventive oil to air dry naturally after polishing and oiling. This avoids the situation where the rust-preventive oil on the workpieces is piled up before it dries due to continuous feeding, which would affect the rust-preventive effect.

A small cylinder 305 is fixedly connected to the bottom of a guide wheel 207. A long rod is provided on the circumference of the small cylinder 305. Through the relative compression of the clamping plate 3, when it enters the grinding area, the bent position can be corrected so that it does not affect the grinding effect in subsequent grinding.

[0019] A grooved plate 311 is fixedly connected to the top of the machine body 1. A telescopic plate 306 is slidably connected to the inner wall of the grooved plate 311. A second spring is provided between the surface of the telescopic plate 306 and the surface of the clamping plate 3. A stop plate 309 is fixedly connected to the surface of the telescopic plate 306. The surface of the stop plate 309 is connected to the inner wall of the grooved plate 311. A triangular block is provided at the bottom of the stop plate 309. A flip plate 307 is rotatably connected to the inner wall of the machine body 1. A limit plate 308 is fixedly connected to the inner wall of the machine body 1. By flipping the flip plate 307, it can be triggered to open after an excessively curved workpiece enters, so that the workpiece falls off the platform and does not enter the grinding process, thus protecting the machine equipment.

[0020] The hole of the movable plate 304 is located on the movement trajectory of the long rod of the small cylinder 305. A No. 1 spring is set between the left side of the movable plate 304 and the inner wall of the bottom shell 208. The compression of the No. 1 spring achieves the reciprocating effect. The triangular block of the abutment plate 309 is located on the bottom movement trajectory of the flip plate 307. The surface of the limiting plate 308 is located on the bottom movement trajectory of the flip plate 307. Steel brushes are fixedly installed on the surfaces of the right grinding wheel 204 and the left grinding wheel 205, which can be replaced. The three guide wheels 211, the two guide wheels 206, the one guide wheel 207, the clamping plate 3, the push plate 301, the movable rod 302, the pull rod 303, the telescopic plate 306, the flip plate 307, the limiting plate 308, the abutment plate 309, and the groove plate 311 are all provided in two symmetrical sets with opposite movement trajectories. The opposite movement can realize the feeding and discharging of materials.

[0021] A right wheel 4 is rotatably connected to the top of the machine body 1, and a left wheel 401 is also rotatably connected to the top of the machine body 1. An oiled cloth 406 is fitted onto the circumferential surfaces of the right wheel 4 and the left wheel 401. A drive rod 403 is rotatably connected to the bottom of the right wheel 4. A long strip is provided on the circumferential surface of the drive rod 403 and the rack 402. A first-hole band 404 is fitted onto the circumferential surface of the drive rod 403 and the rack 402. Multiple holes are evenly spaced through the surface of the first-hole band 404. An auxiliary motor 203 is fixedly connected to the inner wall of the machine body 1. The output end of the auxiliary motor 203 is fixedly connected to the bottom of the drive rod 403. A second long strip is provided on the circumference, and a long strip is provided at the bottom of the left wheel 401. The circumference of the drive rod 403 and the circumference of the left wheel 401 are fitted with a second hollow strip 405. Multiple holes are opened at equal intervals through the surface of the second hollow strip 405. Through the linkage device, the oiling cloth 406 with added rust-preventive oil is driven to wipe and coat the workpiece. The drive will make the oiling cloth 406 rotate slowly. The advantage is that a protective film can be formed on the metal surface to prevent secondary rusting. It also avoids the oiling cloth 406 from rubbing continuously in the same position, which would cause local wear and extend the service life of the oiling cloth 406.

[0022] An oil reservoir 407 is fixedly connected to the top of the machine body 1. An oil guide pipe 408 is fixedly connected to the surface of the oil reservoir 407. A push-button valve 409 is fixedly connected to the port of the oil guide pipe 408. An oil outlet 410 is fixedly connected to the output end of the push-button valve 409. A round protrusion is provided on the top of the left wheel 401. A magnetic block 411 is fixedly connected to the top of the machine body 1. During its rotation, rust-preventive oil can be intermittently added to the oiling cloth 406 through the push-button valve 409. This eliminates the need for manual addition and reduces manual maintenance time.

[0023] The control end of the push-button valve 409 is located above the movement trajectory of the round protrusion of the oil outlet 410. The top of the oiling cloth 406 is located below the bottom of the oil outlet 410, which can keep the anti-rust oil dripping stably onto the oiling cloth 406. The hole 404 of the first cavity band is located above the movement trajectory of the long strip of the drive rod 403 and the rack 402. The hole 405 of the second cavity band is located above the movement trajectory of the second long strip of the drive rod 403 and the long strip of the left wheel 401.

[0024] A storage rack 201 is fixedly connected to the back of the body 1. A rotating rod 501 is fixedly connected to the inner wall of the top cover 2. Two rotating rods 501 are symmetrically arranged. A long rod is set between the inner walls of the rotating rods 501. The circumferential surface of the rotating rod 501 is slidably connected to the top of the clamping plate 3. A rotating plate 5 is rotatably connected to the circumferential surface of the long rod of the rotating rod 501. A straight guide rail 505 is fixedly connected to the inner wall of the top cover 2. A push plate 506 is slidably connected to the surface of the straight guide rail 505. A push rod 504 is fixedly connected to the bottom of the push plate 506. A roller is set on the surface of the push rod 504. The push rod 504 is located on the movement trajectory of the rotating plate 5.

A crossbar 508 is dynamically connected, and a column pusher 509 is slidably connected to the circumferential surface of the long column 513. A flipping plate 507 is sleeved on the circumferential surface of the long column 513. A threaded section is provided on the circumferential surface of the long column 513, and an internal threaded section is provided on the inner wall of the flipping plate 507. The column pusher 509 is located between one end of the crossbar 508 and the flipping plate 507. A No. 3 spring is provided between the inner wall of the storage rack 201 and the other end of the flipping plate 507. Through transmission, the spring is pushed to one side of the storage rack 201 by the pusher plate 507. The flipping is triggered when each workpiece enters, so that the workpiece coated with rust-preventive oil can be stored on the storage rack 201 and left to stand for a period of time, allowing the rust-preventive oil to fully penetrate and dry.

[0025] The top cover 2 is fixedly connected to the outer shell 512. The inner shell 511 is slidably connected to the inner wall of the outer shell 512. The inner wall of the inner shell 511 is slidably connected to the perforated plate 510. The surface of the perforated plate 510 is provided with oil guiding holes. The bottom of the perforated plate 510 is fixedly connected to the vertical pull plate 503. The inner wall of the vertical pull plate 503 is rotatably connected to the surface of the rotating plate 5 with the connecting plate 502. A No. 4 spring is provided between the inner wall of the outer shell 512 and the top of the inner shell 511. The inner wall of the inner shell 511 is provided with oil. At the same time, the feeding speed is controlled by the designed delay mechanism to ensure that each workpiece has enough time to allow the anti-rust oil to air dry naturally after grinding and oiling.

[0026] During operation: The auxiliary motor 203 starts rotating clockwise, driving the drive rod 403 to rotate. The rotation of the drive rod 403 causes its surface strip to rotate clockwise, which in turn causes the first hole belt 404 to rotate clockwise. This rotation of the first hole belt 404 causes the rack 402 to rotate clockwise. The teeth of the rack 402 rotate clockwise, which in turn causes the teeth of the right belt 209 to rotate clockwise. The right belt 209 rotates clockwise, which in turn causes the guide wheel 207 to rotate clockwise, simultaneously causing the small cylinder 305 to rotate clockwise. The rotation of the small cylinder 305 causes its surface strip to rotate clockwise. Through the rotation of the long strip of the small cylinder 305, it gets into the hole of the moving plate 304. Continuing to rotate, it causes the moving plate 304 to move towards the first spring. As the small cylinder 305 rotates... The five long strips detach from the hole in the moving plate 304 and leave. The moving plate 304 is then pushed open by spring number one, thus enabling the reciprocating motion of the moving plate 304. This reciprocating motion of the moving plate 304 drives the pull rod 303 to reciprocate. The pull rod 303 moves forward, causing the moving rod 302 to move to the right. The pull rod 303 moves backward, causing the moving rod 302 to move to the left. The left and right movement of the moving rod 302 causes the push plate 301 to move left and right. The push plate 301 moves left and right along the guide rail at the top of the machine body 1. The left and right movement of the push plate 301 causes the clamping plate 3 to move left and right. At the same time, the other set rotates counterclockwise, thus enabling the clamping plate 3 to move left and right accordingly. The long strip of rusty workpiece is then placed on the inner wall of the clamping plate 3. If a bent workpiece is encountered, the reciprocating pressure of the clamping plate 3 will correct the bend, allowing it to be conveyed in a straight shape to a guide wheel 207. The workpiece is then inserted between the guide wheels 207, which rotate, pushing the workpiece from the outside in. The main motor 202 and the grinding motor 210 are then activated. The main motor 202 rotates counterclockwise, causing the left grinding wheel 205 to rotate counterclockwise, while the grinding motor 210 rotates clockwise, causing the right grinding wheel 204 to rotate clockwise. As the guide wheels 207 continue to push the workpiece until it contacts the left and right grinding wheels 205, the steel brush on the surface of the left grinding wheel 205 begins to clean the rust from one side of the workpiece. The workpiece continues to move and contact... Between the two guide wheels 206, the rotation of the two guide wheels 206 continues to transport the workpiece until it contacts the right grinding wheel 204. The right grinding wheel 204 begins to clean the rust on the other side of the surface. The workpiece continues to be guided by the first guide wheel 207 and the second guide wheel 206 to the third guide wheel 211. Then, the rotation of the third guide wheel 211 transports the remaining part of the workpiece out, thus completing one grinding cycle. Simultaneously, if the workpiece is too bent, it will touch the telescopic plate 306. Continuing to push the workpiece will press the telescopic plate 306 towards the abutment plate 309. As the abutment plate 309 is simultaneously pressed, it moves backward. After being pushed, the abutment plate 309 releases the restriction on the flip plate 307, which then flips downward under gravity.If the flap 307 continues to fall, it will be limited by the stop plate 308, preventing it from falling to the bottom. The workpiece will then fall with the opened flap 307. After the workpiece falls, it will release the restriction on the telescopic plate 306. The telescopic plate 306, after being released, will be bounced back to its original position by the second spring. The return of the telescopic plate 306 will then cause the stop plate 309 to return to its original position. During the return process of the stop plate 309, its inclined surface will cause the bottom of the flap 307 to rise, causing it to close again and re-impose the restriction. This ensures that any excessively curved workpiece will fall, and after falling, the stop plate 309 will re-impose the restriction on the flap 307 to prevent it from affecting the operation of subsequent workpieces.

[0027] As the rack 402 rotates clockwise, it drives the first long strip to rotate. The second long strip of the rack 402 then drives the second hollow belt 405 to rotate. The rotation of the second hollow belt 405 drives the left wheel 401 to rotate clockwise. The rotation of the left wheel 401 drives the surface coating cloth 406 to rotate. The rotation of the coating cloth 406 drives the right wheel 4 to rotate. This allows the right wheel 4 and the left wheel 401 to rotate clockwise. Since the second hollow belt 405 is only rotated once per revolution of the long strip, it slowly drives the right wheel 4 and the left wheel 401 to rotate. This allows the workpiece to be coated with anti-rust oil by the coating cloth 406 as it rotates out from the three guide wheels 211. The slow rotation of the right wheel 4 and the left wheel 401 prevents the coating from remaining in one position, reducing wear on the coating cloth 406. Furthermore, the magnetic block 411 helps to prevent the coating cloth 406 from being used during its rotation. Upon contact with the magnetic block 411, the magnetic block 411 will attract the rust and slag scraped off by the oiling cloth 406 onto its surface. After rotating once, it will not scratch the workpiece surface with rust when it is brushed again. As the left wheel 401 rotates, the round protrusion on its surface will press against the control end of the press valve 409 when it rotates to the bottom of the press valve 409. This triggers the control end of the press valve 409, which outputs some rust-preventive oil into the oil outlet 410. The oil drips onto the oiling cloth 406 through the oil outlet 410. As the left wheel 401 continues to rotate, it will disengage the round protrusion from the control end of the press valve 409, and the press valve 409 will close the oil output. In this way, a certain amount of rust-preventive oil will drip out with each rotation, maintaining the oil content of the oiling cloth 406. This prevents the cloth from running out of rust-preventive oil during the long application process, thus ensuring that subsequent workpieces are not coated with rust-preventive oil.

[0028] With the addition of the rotating plate 5, when the workpiece is input from the clamping plate 3, the workpiece will push the rotating plate 5 up. The pushing of the rotating plate 5 will push the push rod 504 backward. The push rod 504 will move backward along the straight guide rail 505. The movement of the push rod 504 will push the cross bar 508 backward. The movement of the cross bar 508 will push the column pusher 509 to move. The movement of the column pusher 509 will push the flipping plate 507 to move. The movement of the flipping plate 507 will cause it to flip simultaneously due to the threaded section of the long column 513 and its own internal thread. After the workpiece has completely flowed into the machine body 1, the push on the rotating plate 5 is released, and the No. 4 spring will push the flipping plate 507 back to its original position. When plate 507 moves, it flips back. The movement of plate 507 pushes column 509 back to its original position. Column 509 also pushes crossbar 508 back to its original position. The return of crossbar 508 pushes push plate 506 back to its original position, while rotating plate 5 falls back due to gravity. This allows for continued triggering when the next workpiece enters. When a workpiece is pushed onto the surface of storage rack 201, the flipping of plate 507 pushes the workpiece to the right side of the top of storage rack 201. This allows workpieces to be pushed to the right side of storage rack 201 for stacking with each entry and exit. Simultaneously, through the connecting plate 502, when rotating plate 5 is lifted, connecting plate 502 is also lifted. The lifting action will raise the vertical pull plate 503, which in turn will lift the hollow plate 510. As the hollow plate 510 is lifted, the oil between the top of the hollow plate 510 and the top of the inner wall of the inner shell 511 will be squeezed from the oil guide hole to the area between the bottom of the hollow plate 510 and the bottom surface of the inner shell 511. The lifting of the hollow plate 510 will also lift the inner shell 511. The oil is temporarily concentrated between the bottom of the hollow plate 510 and the bottom surface of the inner shell 511. As the workpiece flows into the machine body 1, the rotating plate 5 will move downward due to gravity. The downward movement of the rotating plate 5 will cause the connecting plate 502 to move downward, which in turn will cause the vertical pull plate 503 to move downward, which in turn will cause the hollow plate 510 to move downward. However, the hollow plate 510... During the downward movement, since most of the oil is between the bottom surface of the inner shell 511 and the bottom of the perforated plate 510, the perforated plate 510 will pull the inner shell 511 down as a whole. As the oil slowly flows into the top of the perforated plate 510 and the top of the inner wall of the inner shell 511 through the oil guide hole, the inner shell 511 will be pulled upward by the No. 4 spring. When it is not pulled, the rotating plate 5 will be blocked by the overall frame of the inner shell 511 and cannot be pushed. This can limit the entry of new workpieces. As the inner shell 511 is pulled up, the overall restriction of the inner shell 511 will be released, so that it can start accepting new workpieces again. This can be maintained for a longer time to allow the anti-rust oil on the workpiece to dry, thus physically limiting the entry speed.
