Description

Technical Field

[0001] This invention relates to the field of hot rolling composite equipment technology, specifically to a hot rolling composite equipment for steel pipes. Background Technology

[0002] Hot-rolled composite steel pipe equipment is a special equipment used to produce composite steel pipes. It mainly consists of rolling mill, heating, cooling, and transmission parts. Its working principle is to combine steel pipes of different materials together through heating, rolling and other processes to form composite steel pipes with multiple properties.

[0003] Patent application number CN202021648039.1 relates to a hot rolling guide device and hot rolling equipment for profiles. The hot rolling guide device includes: a support platform, a moving mechanism, the moving mechanism being disposed on the support platform, a clamping mechanism, the clamping mechanism being disposed on the support platform, the moving mechanism being connected to the clamping mechanism, and a control module, the control module being connected to both the moving mechanism and the clamping mechanism. This patent provides stable support by placing the moving mechanism and the clamping mechanism on the support platform, and the clamping mechanism stably clamps the end of the hot-rolled profile. The moving mechanism drives the clamping mechanism to move the hot-rolled profile. During the movement, the support platform can provide a certain degree of support for the hot-rolled profile. However, this device is difficult to effectively heat the steel pipe while guiding it, and cannot guarantee that the steel pipe will maintain its original high temperature during processing. Therefore, a hot rolling composite equipment for steel pipes is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a hot rolling composite equipment for steel pipes, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a hot rolling composite steel pipe equipment, including a worktable, a heating device fixedly connected to the top of the worktable, a motor fixedly connected to the right side of the worktable, a reducing box fixedly connected to the left side of the worktable, a measuring channel fixedly connected to the left side of the reducing box, a cooling box fixedly connected to the left side of the measuring channel, a collecting box fixedly connected to the bottom of the cooling box, a liquid storage tank fixedly connected to the front of the collecting box, a hot rolling mill arranged to the left side of the cooling box, and a rotating sleeve movably connected to the inner wall of the hot rolling mill; a guiding mechanism is arranged at the top of the worktable, a reducing mechanism is arranged to the right side of the hot rolling mill, a scraping mechanism is arranged inside the cooling box, and a measuring mechanism is arranged inside the measuring channel; and the equipment is equipped with a mounting frame and guide rollers. Under the action of the mechanism, the steel pipe is clamped and pushed onto the worktable. The guiding mechanism includes a large rotating wheel, double rotating wheels, a mounting frame, and guide rollers. The large rotating wheel is rotatably connected to the inner wall of the worktable, the double rotating wheels are rotatably connected to the inner wall of the worktable, the mounting frame is slidably connected to the inner wall of the worktable via a connecting rod, and the guide rollers are rotatably connected to the inner wall of the mounting frame. The front of the cooling tank is fixedly connected to the top of the liquid storage tank via a hose. The surface of the large rotating wheel contacts the surface of the double rotating wheels through friction. The rotating rod on the inner wall of the large rotating wheel is fixedly connected to the output end of the motor. When the motor and heating equipment are started, the motor drives the large rotating wheel to rotate, which in turn drives the double rotating wheels to rotate, causing the steel pipe on its surface to rotate, so that it is heated evenly and preventing it from shifting while heating, which would result in an unsatisfactory heating effect and failure to shape.

[0006] Preferably, the amplification mechanism includes a rotating rod, an amplification head, a spreading plate, a spring telescopic rod, an inner cylinder, an inner groove, and a gravity block. The rotating rod is rotatably connected to the inner wall of the rotating sleeve. The amplification head is fixedly connected to the end of the rotating rod away from the rotating sleeve. The spreading plate is rotatably connected to the inner wall of the amplification head. The spring telescopic rod is slidably connected to the inner wall of the amplification head. The inner cylinder is installed inside the amplification head. The inner groove is fixedly connected to the inner wall of the inner cylinder. The gravity block is fixedly connected to the inner wall of the inner cylinder. The rear part of the spreading plate after movement contacts the end of the spring telescopic rod away from the inner cylinder. The surface of the spring telescopic rod is slidably connected to the inner wall of the inner cylinder. The rotating sleeve rotates and drives the internal rotating rod to rotate and move. The rotating rod drives the amplification head to rotate and move. When the amplification head contacts the steel pipe, the steel pipe has been heated and is ductile. The amplification head rotates to expand the diameter of the steel pipe. The spreading plate on the surface of the amplification head contacts the steel pipe, causing the spreading plate to retract into the amplification head. During the retraction process, the spreading plate... The spring telescopic rod contacts the amplification head and retracts into it, releasing the fixed connection between the inner cylinder and the amplification head. The surface of the spring telescopic rod slides against the inner wall of the inner groove, and the surface of the inner groove contacts the surface of the amplification head. The inner wall of the inner cylinder has an oil outlet that communicates with the oil outlet on the inner wall of the amplification head. Under the action of gravity, the inner cylinder will no longer be rotated by the amplification head, and the oil outlet on the inner cylinder will always be in a downward position. When the amplification head enters the steel tube, its oil outlet coincides with the oil outlet on the inner cylinder through rotation, allowing lubricating oil to smoothly enter the inner wall of the steel tube. As the amplification head continues to enter the steel tube, lubricating fluid is sprayed out to re-lubricate the surface of the amplification head every time the oil outlet coincides with the amplification head after one rotation, preventing the lubricating oil from losing its lubricating power in the early stage of the amplification head entering the steel tube, thus increasing the friction. When the amplification head passes through the steel tube, its surface unfolding plate unfolds and locks the other end of the optical tube, allowing it to be pulled back for the next process.

[0007] Preferably, the scraping mechanism includes a trigger block, a lifting rod one, an actuating rod, a fixing block, a scraper one, a lifting rod two, and a scraper two. The trigger block is slidably connected to the inner wall of the cooling box, the lifting rod one is rotatably connected to the inner wall of the cooling box, the actuating rod is slidably connected to the inner wall of the cooling box, the fixing block is fixedly connected to the inner wall of the cooling box, the scraper one is slidably connected to the inner wall of the cooling box, the lifting rod two is rotatably connected to the inner wall of the cooling box, and the scraper two is slidably connected to the inner wall of the cooling box. The scraping mechanism also includes a connecting rod, a friction wheel, and a rotating protrusion. The telescopic block, with the connecting rod fixedly connected to the inner wall of scraper one and the friction wheel fixedly connected to the surface of the connecting rod, causes the trigger block to move downwards and contact lifting rod one when the surface of the steel pipe contacts the trigger block. This causes one end of the lifting rod to tilt and contact the trigger rod, which in turn causes the trigger rod to extend scraper one out of the cooling box, thereby scraping off the oxides generated on the surface of the steel pipe during cooling. Simultaneously, the trigger block causes lifting rod two to tilt, making lifting rod two contact scraper two, lifting scraper two to scrape off the oxides generated at the bottom of the tube. The rotating protrusion is fixedly connected to the surface of the connecting rod. The telescopic block is slidably connected to the inner wall of the rotating protrusion via a spring. After the trigger block moves, its bottom contacts the top of the first lifting rod. After the first lifting rod moves, its top contacts the bottom of the trigger rod. After the trigger block moves, its bottom contacts the top of the second lifting rod. After the end of the trigger rod away from the lifting rod moves, it contacts the surface of the first scraper. After the second lifting rod moves, its top contacts the bottom of the second scraper. The surface of the friction wheel contacts the inner wall of the first scraper. The surface of the rotating protrusion contacts the inner wall of the first scraper. The surface of the telescopic block, after moving, contacts the inner wall of the first scraper. The surface of the steel pipe contacts the friction wheel, causing the friction wheel to rotate. The friction wheel drives the connecting rod to rotate. The connecting rod drives the rotating protrusion and the telescopic block to rotate. When the telescopic block moves to the rectangular hole opened in the first scraper through rotation, the telescopic block loses pressure and is ejected into the rectangular hole by the spring inside the rotating protrusion, striking the surface of the steel pipe, causing the oxides attached to the surface of the steel pipe to fall off further, improving cleaning efficiency.

[0008] Preferably, the measuring mechanism includes a measuring plate, a scale bar, an L-shaped rod, a telescopic rod, a control unit, a guide plate, a connecting rod, and a waste residue basin. The scale bar is slidably connected to the inner wall of the measuring channel. The measuring plate is fixedly connected to the bottom of the scale bar. The L-shaped rod is fixedly connected to the bottom of the scale bar. The telescopic rod is fixedly connected to the top of the L-shaped rod. The control unit is fixedly connected to the left side of the reducing box. The guide plate is fixedly connected to the bottom of the L-shaped rod. Operating the control unit causes the telescopic rod to lift the measuring plate to measure the diameter of the steel pipe. The measurement is performed by observing the scale bar and... The system allows for the timely detection of potential deviations during production, enabling adjustments and improvements. The connecting rod is slidably connected to the inner wall of the guide plate, and the waste residue basin is fixedly connected to the side of the connecting rod away from the guide plate. The top of the telescopic rod is fixedly connected to the output end of the control machine. The surface of the connecting rod is slidably connected to the inner wall of the collection box, and the bottom of the waste residue basin is in contact with the bottom wall inside the collection box. As the telescopic rod rises, it drives the guide plate to rise, thereby causing the connecting rod to move along its inner wall guide groove, which in turn pushes the waste residue basin to discharge the large amount of oxidized waste residue stored inside.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This hot rolling composite steel pipe equipment, through the coordinated operation of the workbench, heating equipment, motor, reducing box, measuring channel, cooling box, liquid storage box, collection box, hot rolling mill, rotating sleeve, guiding mechanism, large roller, double roller, mounting frame, and guide roller, enables the steel pipe to be effectively fixed to prevent deformation during heating, and rotates while heating to ensure uniform heating of the steel pipe, thereby improving the heating effect and keeping the steel pipe at a high temperature throughout the processing.

[0010] 2. This hot-rolled composite steel pipe equipment, through the coordinated operation of the rotating rod, amplification head, unfolding plate, spring telescopic rod, inner cylinder, inner chute, and gravity block, expands the inner diameter of the steel pipe while releasing the lubricating oil stored in the inner cylinder onto the inner wall of the steel pipe. The rotation increases the amplification and composite efficiency, and the intermittent overflow of lubricating oil covers the inner wall of the steel pipe, reducing the friction of the amplification head. Furthermore, when the amplification head passes through the steel pipe, the unfolding plate allows the steel pipe to be pulled back for the next process, thereby improving work efficiency.

[0011] 3. This hot-rolled composite steel pipe equipment, through the coordinated operation of the trigger block, lifting rod one, contact rod, fixing block, scraper one, connecting rod, friction wheel, rotating protrusion, telescopic block, lifting rod two, and scraper two, removes the oxides generated on the surface of the heated and pulled steel pipe. At the same time, the rotating cam and telescopic block strike the steel pipe to make the surface of the steel pipe smooth and flat, improving the surface quality and ensuring product quality.

[0012] 4. This hot-rolled composite steel pipe equipment, through the coordinated operation of the measuring plate, scale bar, L-shaped rod, telescopic rod, control machine, guide plate, connecting rod, and waste slag basin, allows the diameter of the steel pipe to be measured after expansion by the measuring plate and scale bar, ensuring that the diameter of the steel pipe meets the standard requirements, improving product consistency and reliability. The waste slag basin can collect and remove the removed oxides, preventing the accumulation of oxides on the device and the resulting adverse effects. Attached Figure Description

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-8 One embodiment of the present invention is as follows: a hot rolling composite steel pipe device includes a workbench 1, a heating device 2 fixedly connected to the top of the workbench 1, a motor 3 fixedly connected to the right side of the workbench 1, a reducing box 4 fixedly connected to the left side of the workbench 1, a measuring channel 5 fixedly connected to the left side of the reducing box 4, a cooling box 6 fixedly connected to the left side of the measuring channel 5, a collecting box 8 fixedly connected to the bottom of the cooling box 6, a liquid storage tank 7 fixedly connected to the front of the collecting box 8, a hot rolling mill 9 arranged on the left side of the cooling box 6; a rotating sleeve 10 movably connected to the inner wall of the hot rolling mill 9; a guiding mechanism 11 arranged on the top of the workbench 1; a reducing mechanism 12 arranged on the right side of the hot rolling mill 9; a scraping mechanism 13 arranged inside the cooling box 6; and a measuring mechanism 14 arranged inside the measuring channel 5. The guiding mechanism 11 includes a large rotating wheel 1101, a double rotating wheel 1102, a mounting frame 1103, and a guide roller 1104. The large rotating wheel 1101 is rotatably connected to the inner wall of the workbench 1, the double rotating wheel 1102 is rotatably connected to the inner wall of the workbench 1, the mounting frame 1103 is slidably connected to the inner wall of the workbench 1 via a connecting rod, and the guide roller 1104 is rotatably connected to the inner wall of the mounting frame 1103. The front of the cooling tank 6 is fixedly connected to the top of the liquid storage tank 7 via a hose. The surface of the large rotating wheel 1101 contacts the surface of the double rotating wheel 1102 through friction. The rotating rod on the inner wall of the large rotating wheel 1101 is fixedly connected to the output end of the motor 3, so that the steel pipe can be effectively fixed when heated and rotated while heating to ensure that the steel pipe is heated evenly and improve the heating effect. Working principle: The operator will clamp the steel pipe to be composited onto the worktable 1 through the action of the mounting frame 1103 and the guide roller 1104. The operator will start the motor 3 and the heating equipment 2. The motor 3 will drive the large rotating wheel 1101 to rotate, and the large rotating wheel 1101 will drive the double rotating wheel 1102 to rotate, which will cause the steel pipe on its surface to rotate, so that it is heated evenly and prevents it from shifting during heating, which would result in an unsatisfactory heating effect.

[0017] Please see Figure 1-8Based on the above embodiments, in another embodiment of the present invention, the amplification mechanism 12 includes a rotating rod 1201, an amplification head 1202, an unfolding plate 1203, a spring telescopic rod 1204, an inner cylinder 1205, an inner sliding groove 1206, and a gravity block 1207. The rotating rod 1201 is rotatably connected to the inner wall of the rotating sleeve 10. The amplification head 1202 is fixedly connected to the end of the rotating rod 1201 away from the rotating sleeve 10. The unfolding plate 1203 is rotatably connected to the inner wall of the amplification head 1202. The spring telescopic rod 1204 is slidably connected to the inner wall of the amplification head 1202. The inner cylinder 1205 is installed inside the amplification head 1202. The inner sliding groove 1206 is fixedly connected to the inner wall of the inner cylinder 1205. The gravity block 1207 is fixedly connected to the inner wall of the inner cylinder 1205. After the expansion plate 1203 moves, its rear part contacts the end of the spring telescopic rod 1204 away from the inner cylinder 1205. The surface of the spring telescopic rod 1204 is slidably connected to the inner wall of the inner cylinder 1205. The surface of the spring telescopic rod 1204 is slidably connected to the inner wall of the inner slide groove 1206. The surface of the inner slide groove 1206 is in contact with the surface of the amplification head 1202. The inner wall of the inner cylinder 1205 is provided with an oil outlet, which is connected to the oil outlet on the inner wall of the amplification head 1202. By rotating, the amplification efficiency is improved, and the lubricating oil is evenly distributed on the inner wall of the steel pipe, reducing the friction of the amplification head 1202. When the amplification head 1202 passes through the steel pipe, the steel pipe can be pulled back under the action of the expansion plate 1203 to directly proceed to the next process, thereby improving work efficiency. Working principle: After the steel pipe is heated, the hot rolling mill 9 is operated to push and rotate the rotating sleeve 10. The rotating sleeve 10 rotates and drives the internal rotating rod 1201 to rotate and move. The rotating rod 1201 drives the expansion head 1202 to rotate and move. When the expansion head 1202 contacts the steel pipe, the steel pipe has been heated and is ductile. The expansion head 1202 rotates to expand the diameter of the steel pipe. The unfolding plate 1203 on the surface of the expansion head 1202 contacts the steel pipe, causing the unfolding plate 1203 to retract into the expansion head 1202. During the retraction process, the unfolding plate 1203 contacts the spring telescopic rod 1204. The spring telescopic rod 1204 retracts into the expansion head 1202, releasing the fixed connection between the inner cylinder 1205 and the expansion head 1202. Under the action of gravity block 1207, the inner cylinder 1205 will no longer be driven to rotate by the amplification head 1202, and the oil outlet of the inner cylinder 1205 will always be in a downward position. When the amplification head 1202 enters the steel pipe, its oil outlet will coincide with the oil outlet of the inner cylinder 1205 through rotation, so that the lubricating oil can smoothly enter the inner wall of the steel pipe. As the amplification head 1202 continues to enter the steel pipe, the lubricating fluid can be sprayed out to re-lubricate the surface of the amplification head 1202 every time the oil outlet coincides after one rotation, to prevent the lubricating oil from losing its lubricating force in the early stage of the amplification head 1202 entering the steel pipe, thereby increasing the friction. When the amplification head 1202 passes through the steel pipe, its surface unfolding plate 1203 unfolds and locks the other end of the optical tube, so that it can be pulled back to the next process.

[0018] Please see Figure 1-8Based on the above embodiments, in another embodiment of the present invention, the scraping mechanism 13 includes a trigger block 1301, a lifting rod 1302, an actuating rod 1303, a fixing block 1304, a scraper 1305, a lifting rod 1310, and a scraper 1311. The trigger block 1301 is slidably connected to the inner wall of the cooling box 6, the lifting rod 1302 is rotatably connected to the inner wall of the cooling box 6, the actuating rod 1303 is slidably connected to the inner wall of the cooling box 6, and the fixing block 1304 is fixedly connected to the cooling box 6. The scraping mechanism 13 also includes a connecting rod 1306, a friction wheel 1307, a rotating protrusion 1308, and a telescopic block 1309. The connecting rod 1306 is fixedly connected to the inner wall of the scraper 1305, the friction wheel 1307 is fixedly connected to the surface of the connecting rod 1306, and the rotating protrusion 1308 is fixedly connected to the inner wall of the cooling box 6. Connected to the surface of connecting rod 1306, telescopic block 1309 is slidably connected to the inner wall of rotating protrusion 1308 via spring. After the trigger block 1301 moves, its bottom contacts the top of lifting rod 1302. After the lifting rod 1302 moves, its top contacts the bottom of trigger rod 1303. After the trigger block 1301 moves, its bottom contacts the top of lifting rod 1310. After the end of trigger rod 1303 away from lifting rod 1302 moves, it contacts the surface of scraper 1305. The top of the lifting rod 1310 after it moves comes into contact with the bottom of the scraper 1311 after it moves; the surface of the friction wheel 1307 comes into contact with the inner wall of the scraper 1305 after it moves; the surface of the rotating protrusion 1308 comes into contact with the inner wall of the scraper 1305 after it moves; and the surface of the telescopic block 1309 after it moves comes into contact with the inner wall of the scraper 1305 after it moves. This process removes the oxides generated on the surface of the heated and pulled steel pipe, making the surface of the steel pipe smooth and flat, improving the surface quality, and ensuring the product quality. Working principle: When the amplifier head 1202 pulls the steel pipe into the cooling box 6 via the reducing box 4, the pneumatic device at the top of the cooling box 6 draws coolant from the storage tank 7 and allows it to flow out through a circular hole inside the cooling box 6 to cool the steel pipe. When the surface of the steel pipe contacts the trigger block 1301, the trigger block 1301 moves downward and contacts the lifting rod 1302. This causes the lifting rod 1302 to tilt at one end and contact the trigger rod 1303, which in turn causes the trigger rod 1303 to drive the scraper 1305 to extend into the cooling box 6, thereby scraping off the oxides generated on the surface of the steel pipe during cooling. Simultaneously, the trigger block 1301 causes the lifting rod 1310 to tilt, thus... Rod 2 1310 contacts scraper 2 1311, lifting scraper 2 1311 to scrape off oxides generated at the bottom of the tube. The surface of the steel tube contacts friction wheel 1307, causing friction wheel 1307 to rotate. Friction wheel 1307 drives connecting rod 1306 to rotate, and connecting rod 1306 drives surface rotating protrusion 1308 and telescopic block 1309 to rotate. When telescopic block 1309 moves to the rectangular hole opened by scraper 1 1305 through rotation, telescopic block 1309 loses pressure and is ejected into the rectangular hole by spring inside rotating protrusion 1308, striking the surface of the steel tube, causing the oxides attached to the surface of the steel tube to fall off further, improving cleaning efficiency.

[0019] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, the measuring mechanism 14 includes a measuring plate 1401, a scale bar 1402, an L-shaped rod 1403, a telescopic rod 1404, a control unit 1405, a guide plate 1406, a connecting rod 1407, and a waste container 1408. The scale bar 1402 is slidably connected to the inner wall of the measuring channel 5. The measuring plate 1401 is fixedly connected to the bottom of the scale bar 1402. The L-shaped rod 1403 is fixedly connected to the bottom of the scale bar 1402. The telescopic rod 1404 is fixedly connected to the top of the L-shaped rod 1403. The control unit 1405 is fixedly connected to the left side of the reducing box 4. The guide plate 1406 is fixedly connected to the bottom of the measuring channel 5. Connected to the bottom of L-shaped rod 1403, connecting rod 1407 is slidably connected to the inner wall of guide plate 1406, waste slag basin 1408 is fixedly connected to the side of connecting rod 1407 away from guide plate 1406, top of telescopic rod 1404 is fixedly connected to the output end of controller 1405, surface of connecting rod 1407 is slidably connected to inner wall of collection box 8, bottom of waste slag basin 1408 is in contact with bottom wall inside collection box 8, ensuring that steel pipe diameter meets standard requirements, improving product consistency and reliability, and waste slag basin 1408 can collect and remove removed oxides, preventing oxides from accumulating on the device and causing adverse effects; Working principle: When the steel pipe is pulled back into the measuring channel 5, the operating controller 1405 causes the telescopic rod 1404 to drive the measuring plate 1401 to rise and measure the diameter of the steel pipe. By observing the scale bar 1402, any deviations that may occur during the production process can be detected in time for adjustment and improvement. As the telescopic rod 1404 rises, it also drives the guide plate 1406 to rise, thereby causing the connecting rod 1407 to move along the guide groove on its inner wall, which in turn pushes the waste slag basin 1408 to discharge the large amount of oxidized waste stored inside.
