Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe production equipment, in particular to a pipe rolling device for producing plastic-coated anti-corrosion steel pipes. Background Art

[0002] A pipe rolling device is a device used to calender, extrude or roll metal materials (such as steel, aluminum, etc.). In the production and processing of steel pipe structures, the pipe rolling device is often used to process steel billets into pipes by extrusion or rolling. Its basic principle is to use rollers to calender, stretch or extrude the steel billet, so that it is gradually formed into a steel pipe of the required size and shape.

[0003] When using a pipe rolling device to process steel pipes, some debris and other impurities may adhere to the surface of the processed steel pipes. The impurities will affect the adhesion between the coating and the steel pipe surface, causing the coating to easily peel or fall off, reducing the corrosion resistance of the coating. Therefore, it is necessary to clean the steel pipe surface before coating. Cleaning the steel pipe alone increases the number of processes, extends the production cycle, and thus reduces production efficiency. Utility Model Content

[0005] The utility model provides the following technical solution: a pipe rolling device for producing plastic-coated anti-corrosion steel pipes, comprising a rolling mill body, a water trough mounted on one side of the discharge end of the rolling mill body, two collars mounted on the upper side of the water trough via a reciprocating mechanism, a rotating ring rotatably mounted inside each collar, and bristles evenly arranged on the inner walls of the rotating rings. First mounting plates are connected to the inner walls of both sides of the water trough, an annular water pipe is mounted on the opposing surfaces of the two first mounting plates, and nozzles are evenly mounted on the inner walls of the annular water pipe. A water pump is mounted on the outer surface of the water trough, and an outlet pipe is connected to the end of the water pump output end, and the end of the outlet pipe is connected to the annular water pipe.

[0006] Preferably, the reciprocating motion mechanism includes a motor installed on one side of the discharging end of the rolling mill body, the end of the motor output shaft is connected to a reciprocating screw, the outer surface of the reciprocating screw is installed with a slider, one side of the discharging end of the rolling mill body is connected to a limit rod, and the slider is slidably installed on the limit rod, the lower surface of the slider is connected to two connecting rods, and the ends of the two connecting rods are respectively connected to two rings.

[0007] Preferably, a connecting plate is connected between the two collars, a sliding groove is provided on the outer surface of the connecting plate, a sliding rod is connected to the inner wall of the water trough, and the end of the sliding rod is arranged in the sliding groove.

[0008] Preferably, a filter plate is installed inside the water tank, and filter holes are evenly opened on the surface of the filter plate.

[0010] Preferably, a bracket is installed on the upper side of the water tank, the end of the reciprocating screw is rotatably connected to the bracket, and the end of the limiting rod is fixedly connected to the bracket.

[0011] Compared with the existing technology, the beneficial effects of the utility model are:

[0012] (1) When the steel pipe processed by the rolling mill body passes through the two rotating rings and the annular water pipe in turn, the reciprocating motion mechanism drives the two sleeves to reciprocate, so that the bristles clean the surface of the steel pipe and remove large particles of debris and other impurities. Then, the water in the water tank is pumped out by the water pump and enters the annular water pipe. The steel pipe is flushed from different directions by the nozzle, so that the fine impurities on the surface of the steel pipe can be cleaned. Through the front and back cleaning methods, it can be ensured that the impurities on the surface of the steel pipe are cleaned and the cleanliness is guaranteed, thereby eliminating the additional processing steps of subsequent cleaning, reducing the production cycle, and thus improving production efficiency. In addition, after the steel pipe is extruded, its surface has a high temperature. Therefore, when the nozzle sprays water for flushing, it can also cool the surface of the steel pipe to avoid burns to workers when taking materials, thus killing two birds with one stone.

[0019] like Figures 1 to 5 As shown, a pipe rolling device for the production of plastic-coated anti-corrosion steel pipes includes a rolling machine body 1, a water trough 2, a collar 3, a rotating ring 4, bristles 5, a first mounting plate 6, an annular water pipe 7, a nozzle 8, a water pump 9, a water outlet pipe 10, a reciprocating motion mechanism 11, a motor 12, a reciprocating screw 13, a slider 14, a limit rod 15, a connecting rod 16, a connecting plate 17, a slide 18, a slide rod 19, a filter plate 20, a second mounting plate 21, a scraper 22 and a bracket 23.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of this utility model, unless otherwise specified, "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 5 As shown, a water trough 2 is installed on one side of the discharging end of the rolling mill body 1, and two rings 3 are installed on the upper side of the water trough 2 through a reciprocating motion mechanism 11. Rotating rings 4 are rotatably installed inside the two rings 3, and bristles 5 are evenly arranged on the inner wall of the rotating ring 4. When the steel pipe passes through the inside of the rotating ring 4, the rotating ring 4 is driven by the reciprocating motion mechanism 11 to reciprocate on the outer surface of the steel pipe along its length direction, thereby driving the bristles 5 to clean the surface of the steel pipe.

[0024] The inner walls on both sides of the water tank 2 are connected to a first mounting plate 6, and an annular water pipe 7 is commonly installed on the opposite surfaces of the two first mounting plates 6. Nozzles 8 are evenly installed on the inner walls of the annular water pipe 7. A water pump 9 is installed on the outer surface of the water tank 2, and the end of the output end of the water pump 9 is connected to a water outlet pipe 10. The end of the water outlet pipe 10 is connected to the annular water pipe 7. The water pump 9 draws water out of the water tank 2 and into the annular water pipe 7, and then the nozzle 8 rinses the outer surface of the steel pipe to remove fine impurities on the surface of the steel pipe.

[0025] A filter plate 20 is installed inside the water tank 2. The surface of the filter plate 20 is evenly provided with filter holes. The debris cleaned from the steel pipe can be filtered by the filter plate 20 to prevent it from falling into the water, thereby improving the cleanliness of the water, facilitating recycling, reducing the waste of water resources, and facilitating the collection of the cleaned debris and impurities.

[0026] The inner walls on both sides of the water tank 2 are connected to a second mounting plate 21, and the opposite surfaces of the two second mounting plates 21 are jointly installed with a scraper 22. There are still water stains on the surface of the steel pipe after being washed with water. When it passes through the scraper 22, the scraper 22 can scrape off the water stains on its surface and fall back into the water tank 2 for recycling, thereby improving the drying speed of the steel pipe. The part of the scraper 22 that contacts the steel pipe can be made of rubber or silicone material, which has a certain deformation ability and can be well wrapped around the outer surface of the steel pipe to scrape off the water stains without scratching the steel pipe.

[0027] The reciprocating motion mechanism 11 includes a motor 12 installed on one side of the discharging end of the rolling mill body 1, and the end of the output shaft of the motor 12 is connected to a reciprocating screw 13. The outer surface of the reciprocating screw 13 is installed with a slider 14. The side of the discharging end of the rolling mill body 1 is connected to a limiting rod 15, and the slider 14 is slidably installed on the limiting rod 15. Two connecting rods 16 are connected to the lower surface of the slider 14, and the ends of the two connecting rods 16 are respectively connected to the two rings 3. Since the slider 14 is limited by the limiting rod 15, when the motor 12 is started to drive the reciprocating screw 13 to rotate, the slider 14 can be driven to reciprocate along the surface of the reciprocating screw 13. Therefore, through the connecting action of the connecting rod 16, the purpose of driving the two rings 3 to reciprocate on the outer surface of the steel pipe can be achieved, so that the bristles 5 can clean the outer surface of the steel pipe.

[0028] A bracket 23 is installed on the upper side of the water tank 2. The end of the reciprocating screw rod 13 is rotatably connected to the bracket 23, and the end of the limit rod 15 is fixedly connected to the bracket 23. Through the setting of the bracket 23, the ends of the reciprocating screw rod 13 and the limit rod 15 can be supported to improve their structural strength, thereby improving the stability of the slider 14 when moving.

[0029] A connecting plate 17 is connected between the two collars 3, and a slide groove 18 is provided on the outer surface of the connecting plate 17. A slide rod 19 is connected to the inner wall of the water trough 2, and the end of the slide rod 19 is set in the slide groove 18. When the two collars 3 reciprocate together with the connecting plate 17, since the rotating ring 4 and the collar 3 are rotatably connected, under the action of the slide groove 18 and the slide rod 19, the two collars 3 and the connecting plate 17 can rotate back and forth, thereby improving the cleaning effect of the bristles 5 on the surface of the steel pipe, and can sweep impurities to both sides into the water trough 2 to avoid accumulation on the upper side of the steel pipe.

[0030] The working principle of the present invention is as follows: the steel pipe processed by the rolling mill body 1 extends from the discharge end and passes through the inside of the two rotating rings 4 and the annular water pipe 7 in sequence. When the steel pipe passes through the rotating ring 4, the bristles 5 contact its surface. Then, driven by the reciprocating motion mechanism 11, the two sleeve rings 3 drive the bristles 5 to reciprocate on the outer surface of the steel pipe. Since the discharge speed of the steel pipe is lower than the movement speed of the sleeve ring 3, the bristles 5 can clean each area of the steel pipe multiple times to ensure that large particles of debris are cleaned. When the steel pipe cleaned by the bristles 5 passes through the annular water pipe 7, the water pump can be started. 9. The water pump 9 pumps out the water inside the water tank 2, sends it to the annular water pipe 7 through the water outlet pipe 10, and then sprays it out from the nozzle 8, so that the steel pipe can be flushed from multiple directions, and the fine impurities on the surface of the steel pipe can be cleaned. Through the front and back cleaning methods, it can be ensured that the impurities on the surface of the steel pipe are cleaned and the cleanliness is guaranteed, thereby eliminating the additional processing steps of subsequent separate cleaning, reducing the production cycle, and thus improving production efficiency. Finally, the rinsed steel pipe passes through the scraper 22, and the scraper 22 scrapes off the water stains on the surface of the steel pipe and falls back into the water tank 2 for recycling, so that the steel pipe can be dried quickly.

[0031] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
