Description

Technical Field

[0001] This utility model relates to a tube-making machine, specifically a tube-making machine with a rust-removing edge structure for feeding sheet material, belonging to the technical field of tube-making machines. Background Technology

[0002] Currently, tube-making machines are mainly used for the continuous forming process of stainless steel and carbon steel (round tubes, square tubes, and special-shaped tubes) for decorative and industrial use. The process involves uncoiling, forming, welding, grinding, sizing, straightening, length setting, and cutting. After uncoiling, the sheet material is fed into the tube-making machine and bent into tubes by pressure rollers. The butt joints are then welded to form fittings. During feeding, the sheet material undergoes multiple steps such as cutting, coiling, transportation, and storage before entering the uncoiling process, resulting in a long cycle and often leaving uneven edges. Rust often occurs, and the edges are welding areas. When rust is present, welding defects are likely to occur, affecting the overall quality. Therefore, when the sheet is fed into the tube making machine, the rust at the edges needs to be removed. Currently, most methods involve manual wiping or using fixed wire brushes to remove rust as the sheet passes through. However, these methods are inefficient and only remove a shallow amount of rust, resulting in poor rust removal. Furthermore, the friction between the wire brush and the sheet causes severe wear on the wire brush, requiring frequent replacement. This replacement operation is difficult and inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a tube making machine with a rust removal edge structure for feeding sheet material in order to solve the above problems. It can effectively remove rust from the edge of the sheet material, improve the rust removal effect, and facilitate maintenance and collection of the removed rust.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a tube-making machine with a rust-removing edge structure for feeding sheet material, comprising a tube-making machine body.

[0005] The feeding rack is fixedly installed on one side of the tube making machine body to transport the sheet material into the interior of the tube making machine body.

[0006] Guide rollers and feed rollers are respectively installed on both sides of the feed frame. The feed rollers are located on the side closer to the tube making machine body and are used to transport the sheet material.

[0007] A rust removal assembly is symmetrically and rotatably mounted on both sides of the feed rack. The rust removal assembly is located between the guide rollers and the feed rollers, and is parallel to the feeding direction of the sheet. The rust removal assembly contacts the edge of the sheet to remove the rust from the sheet.

[0008] Preferably, servo motors are fixedly installed symmetrically on both sides of one end of the feeding rack. The servo motors drive the rust removal component, which facilitates the rotation of the rust removal component in a direction parallel to the sheet material to remove rust from the edge of the sheet material.

[0009] Preferably, a first pulley is fixedly installed at one end of the rust removal component, and a drive pulley is fixedly installed at the output end of the servo motor. The drive pulley is linked with the first pulley, so that when the servo motor drives the drive pulley to rotate, the first pulley rotates synchronously to drive the rust removal component.

[0010] Preferably, a magnetic roller is rotatably mounted on one side of the feed rack between the vertically distributed rust removal components. A second pulley is fixedly mounted on one end of the magnetic roller. An upper servo motor drives the drive pulley to link with the second pulley. A scraper is fixedly mounted on one side of the feed rack between the magnetic rollers. One side of the scraper contacts the magnetic roller, which facilitates the servo motor to drive the magnetic roller to rotate in the same direction as the upper rust removal components. This collects the iron filings polished off during rust removal and scrapes them off with the scraper, reducing splashing.

[0011] Preferably, the rust removal assembly includes a rotating shaft rotatably mounted on the feed rack, with rubber brushes fixedly mounted in an array on the rotating shaft. The outer side of each rubber brush has an arc-shaped structure. Rust-removing wire brushes are mounted in a circumferential array on the rotating shaft between the rubber brushes. The rust-removing wire brushes remove rust from the edges of the sheet material by rotating, and the rubber brushes scrape off the debris generated during rust removal and discharge the debris.

[0012] Preferably, a square mounting base is fixedly installed on the rotating shaft between the rubber brushes, and the rust-removing wire brush is installed on the mounting base, which facilitates the installation of the rust-removing wire brush and allows for quick replacement.

[0013] Preferably, a mounting plate is fixedly installed on one side of the rust-removing wire brush, and Velcro is fixedly installed on both the mounting base and the mounting plate. The mounting plate is attached to the mounting base by the Velcro, which facilitates the quick and easy fixing of the rust-removing wire brush to the mounting base and makes installation convenient.

[0014] Preferably, the mounting base has a square pin hole between the Velcro straps, and a pin is fixedly mounted on the mounting plate. The pin is inserted into the pin hole, which improves the stability of the installation between the rust-removing wire brush and the mounting base, and improves the stability during rust removal.

[0015] The beneficial effects of this utility model are as follows: the sheet material is unwound and flattened and conveyed into the body of the tube making machine by the guide rollers and the feeding rollers. During the conveying, the servo motor drives the rust removal component to rotate and remove rust from the edge of the sheet material. During rust removal, the rust removal wire brushes and rubber brushes are intermittently distributed to facilitate the discharge of rust debris, reducing the impact of rust debris on the sheet material. The quick-installation rust removal wire brushes are easy to replace, and the magnetic rollers facilitate the adsorption and collection of debris, reducing splashing. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6As shown, a tube-making machine with a sheet material derusting edge structure includes a tube-making machine body 1 (not fully shown in the figure). The feeding end of the tube-making machine body 1 is fixedly installed on one side of the feeding frame 2 for conveying the sheet material into the interior of the tube-making machine body 1. Guide rollers 3 and feeding rollers 4 are respectively installed on both sides of the feeding frame 2. The feeding rollers 4 are located on the side closer to the tube-making machine body 1 for conveying the sheet material. A derusting assembly 5 is symmetrically rotated on both sides of the feeding frame 2. The derusting assembly 5 is located between the guide rollers 3 and the feeding rollers 4, and is parallel to the feeding direction of the sheet material. The derusting assembly 5 contacts the edge of the sheet material for derusting the sheet material. For rust removal, during use, the uncoiled sheet is introduced into the tube making machine body 1 through the feed rack 2. During introduction, the sheet is pulled and guided by the guide rollers 3 and the feed rollers 4, so that the sheet is flattened between the guide rollers 3 and the feed rollers 4. The edge of the flattened sheet passes between the rust removal components 5 distributed on both sides. The rust removal components 5 rotate, and the rotation axis of the rust removal components 5 is parallel to the forward direction of the sheet. This allows the rust removal components 5 to grind and remove rust from the edge of the sheet, reducing the impact of rust on the edge of the sheet and causing a decrease in welding quality, thereby improving the stability and quality of tube production.

[0025] Servo motors 6 are symmetrically fixed on both sides of one end of the feed rack 2, driving the rust removal component 5. A first pulley 7 is fixedly installed on one end of the rust removal component 5, and a drive pulley 8 is fixedly installed on the output end of the servo motor 6. The drive pulley 8 is linked with the first pulley 7. A magnetic roller 9 is rotatably installed on one side of the feed rack 2 between the vertically distributed rust removal components 5. A second pulley 10 is fixedly installed on one end of the magnetic roller 9. The upper servo motor 6 drives the drive pulley 8 and the second pulley 10 to link together, and the feed rack 2 is located between the magnetic components. A scraper 11 is fixedly installed on one side of the iron roller 9. One side of the scraper 11 is in contact with the magnetic roller 9. A transmission belt is connected between the first pulley 7 and the drive pulley 8, and between the drive pulley 8 and the second pulley 10. When the servo motor 6 drives the drive pulley 8 to rotate, the rust removal component 5 rotates to grind and remove rust from the edge of the sheet. The second pulley 10 drives the magnetic roller 9 to rotate, adsorbing the iron filings generated during grinding. After adsorption, the filings are scraped off by the scraper 11, which facilitates the collection of rust or iron filings and reduces the splashing of filings.

[0026] The rust removal assembly 5 includes a rotating shaft 501 rotatably mounted on the feed rack 2. Rubber brushes 502 are fixedly mounted in an array on the rotating shaft 501. The outer side of each rubber brush 502 has an arc-shaped structure. Rust removal wire brushes 503 are mounted in a circumferential array on the rotating shaft 501 between the rubber brushes 502. A square mounting base 504 is fixedly mounted on the rotating shaft 501 between the rubber brushes 502. The rust removal wire brushes 503 are mounted on the mounting base 504. A mounting plate 505 is fixedly mounted on one side of each rust removal wire brush 503. Velcro 506 is fixedly mounted on both the mounting base 504 and the mounting plate 505. The mounting plate 505 is adhered to the mounting base 504 via the Velcro 506. Square pin holes 507 are formed between the Velcro 506 on the mounting base 504, and pins 508 are fixedly mounted on the mounting plate 505. The pins 508 are inserted into... Inside the pin hole 507, when using the rust removal component 5, the rust removal wire brush 503 is first inserted into the pin hole 507 on the mounting base 504 through the pin rod 508 on the mounting plate 505, and then glued together with Velcro 506 to fix the rust removal wire brush 503 on the mounting base 504. When the servo motor 6 drives the rotating shaft 501 to rotate, the rust removal wire brush 503 and the rubber brush 502 rotate. The rust removal wire brush 503 grinds the rusted area and removes the rust debris. The debris generated during grinding is discharged by the centrifugal force of the rust removal wire brush 503 and the cleaning of the rubber brush 502, reducing the impact of debris on subsequent grinding. When the rust removal wire brush 503 becomes worn, it is convenient to replace the rust removal wire brush 503 on the mounting base 504, improving the convenience of later maintenance.
