Description

Technical Field

[0001] This invention relates to the field of rolling equipment technology, specifically a high-nickel stainless steel rolling equipment with tension control function. Background Technology

[0002] High-nickel stainless steel is a type of stainless steel material with a high nickel content. It has excellent corrosion resistance, high temperature resistance, and good plasticity and toughness. It is widely used in fields with extremely high material performance requirements, such as chemical equipment, nuclear power, aerospace and deep-sea engineering. Due to the special composition and structure of high-nickel stainless steel, its strength and hardness are generally higher than those of ordinary stainless steel, and the load-bearing capacity requirements of the rolls and transmission system are higher during the rolling process.

[0003] Existing rolling equipment has several defects: during the rolling process, excessive rolling force can easily lead to rolling cracks, edge cracks, or even internal defects; before rolling, the raw materials may have dust, impurities, and small metal particles adhering to them. These foreign objects can be pressed into the material during the rolling process, resulting in scratches, inclusions, or surface defects, affecting the quality and performance of the finished product; during the transportation of raw materials, deviations may occur, leading to uneven rolling thickness, edge waviness, or plate shape defects. Summary of the Invention

[0004] The technical problems to be solved by the present invention are excessive tension during rolling, dirt on the surface of raw materials, and deviation during transportation. The present invention provides a high-nickel stainless steel rolling equipment with tension control function.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A high-nickel stainless steel rolling equipment includes a base, on which a first motor is mounted. A gearbox is mounted on one side of the first motor, and a first coupling and a second coupling are mounted on one side of the gearbox. A first connecting shaft is mounted on one side of the first coupling, and a second connecting shaft is mounted on one side of the second coupling. A rolling device is mounted on one side of the first connecting shaft, and a cleaning device is mounted on one end of the rolling device. A correction device is mounted on one end of the cleaning device. The gearbox, rolling device, cleaning device, and correction device are mounted on the base, and the first motor is connected to a control system. During the rolling process, the first motor is started, driving the gears in the gearbox to rotate. The gearbox drives the first coupling and the second coupling to rotate, the first coupling drives the first connecting shaft to rotate, and the second coupling drives the second connecting shaft to rotate.

[0006] The rolling apparatus includes a frame mounted on a base. A groove is provided on the frame, within which a first mounting plate and a tensioning device are installed. A first roll is rotatably mounted within the first mounting plate. A strain gauge sensor is mounted below the first mounting plate. A first gear is mounted on one side of the first roll, and a third coupling is mounted on the other side of the first roll. The third coupling is mounted on a first connecting shaft. The tensioning device is located above the first roll. A support plate is mounted on one side of the frame, and a pressing device is mounted on the support plate. The strain gauge sensor is connected to a control system. The first connecting shaft drives the third coupling to rotate, the third coupling drives the first roll to rotate, and the first roll drives the first gear to rotate.

[0007] The tensioning device includes a second mounting plate that slides within a groove. A sliding groove is provided on the second mounting plate, within which a slider is slidably mounted. A second roller is rotatably mounted within the slider. A fourth coupling is mounted on one side of the second roller and is installed on a second connecting shaft. An elastic damper is mounted at the upper end of the sliding groove, with one end of the elastic damper mounted on the slider. A hydraulic cylinder is mounted at the lower end of the sliding groove, with its cylinder rod mounted on the slider. The hydraulic cylinder is connected to a control system. The second connecting shaft drives the fourth coupling to rotate, which in turn drives the second roller to rotate. When a strain gauge sensor detects excessive tension, the control system activates the hydraulic cylinder. The cylinder rod extends, causing the slider to slide within the sliding groove. The slider moves towards the elastic damper, which in turn drives the second roller to move towards the elastic damper. The elastic damper reduces vibration during slider movement.

[0008] The pressing device includes a second motor mounted on a support plate. A rotating rod is mounted on one side of the second motor, and a worm gear is mounted on the rotating rod. A sealing box is mounted on the support plate, and the worm gear is located inside the sealing box. A partition is installed inside the sealing box, and a lead screw is rotatably mounted on the partition. A worm wheel is mounted on one end of the lead screw, and a pressing nut is slidably mounted on the lead screw. The pressing nut is mounted on a second mounting plate, and a pressure plate is mounted on one end of the pressing nut. The pressure plate is located below the partition. A guide rod is mounted on one side of the pressure plate, and one end of the guide rod is mounted on the second mounting plate. A first spring is sleeved on the outside of the guide rod, and one end of the first spring is mounted on the pressure plate. The other end of the first spring is mounted on the support plate. The second motor is connected to the control system. Before rolling, the second motor is started. The output shaft of the second motor drives the rotating rod to rotate, which in turn drives the worm gear to rotate. The worm gear drives the worm wheel to rotate, which in turn drives the lead screw to rotate. The lead screw drives the lower pressure nut to slide on the lead screw. The lower pressure nut slides away from the worm wheel, which in turn drives the second mounting plate to slide away from the worm wheel until it slides to the predetermined position. The lower pressure nut then drives the pressure plate to move away from the worm wheel. The pressure plate presses on the first spring, which can balance the load and eliminate the weight of the roll.

[0009] The cleaning device includes a base plate mounted on a base, side plates mounted on the base plate, a transmission device mounted on one side of the side plates, a cleaning roller rotatably mounted between the two side plates, a flywheel rotatably mounted on the other side of the side plates, the flywheel mounted on the transmission device, and a recycling device mounted above the cleaning roller, located between the two side plates.

[0010] The transmission device includes a second gear, a first cylinder mounted on a side plate, a third gear mounted on the first cylinder, a second gear mounted on one side of the third gear, belts mounted on the outer sides of the first and second gears, a fourth gear and a first bevel gear mounted on the cleaning roller, the third gear and the fourth gear meshing, a horizontal plate mounted on the side plate, a second cylinder and a support frame mounted on the horizontal plate, a second bevel gear mounted on the second cylinder, a first rotating shaft rotatably mounted on the support frame, a third bevel gear mounted on the first rotating shaft, the first bevel gear and the second bevel gear meshing, the second bevel gear and the third bevel gear meshing, a centrifugal clutch mounted on the first rotating shaft, a second rotating shaft rotatably mounted inside the cleaning roller, a centrifugal clutch installed inside the second rotating shaft, a flywheel mounted on the second rotating shaft, and a centrifugal device mounted on the second rotating shaft. The first gear drives the belt to rotate, the belt drives the second gear to rotate, the second gear drives the third gear to rotate, the third gear drives the fourth gear to rotate, the fourth gear drives the cleaning roller to rotate, the cleaning roller drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the third bevel gear to rotate, the third bevel gear drives the first shaft to rotate, the first shaft drives the centrifugal clutch to rotate, the centrifugal clutch engages, the centrifugal clutch drives the second shaft to rotate, the second shaft drives the flywheel and centrifugal device to rotate, the flywheel stores kinetic energy, when the machine stops or the rolling process is interrupted, the first motor stops, causing the first shaft to stop rotating, the centrifugal clutch disengages, the flywheel releases kinetic energy and drives the second shaft to decelerate and rotate.

[0011] The centrifuge device includes a centrifuge shell, which is mounted on a second rotating shaft. A centrifuge tank is provided on the centrifuge shell. A limit plate is slidably installed inside the centrifuge tank. A connecting column is installed on one side of the limit plate, and an arc-shaped block is installed on one side of the connecting column. A second spring is sleeved on the outside of the connecting column. One end of the second spring is installed on the limit plate, and the other end of the second spring is installed on the centrifuge shell. The second rotating shaft drives the centrifugal shell to rotate. Under the action of centrifugal force, the connecting column moves away from the center of the centrifugal shell. The connecting column drives the arc-shaped block to move away from the center of the centrifugal shell. The arc-shaped block presses against the inner wall of the cleaning roller. The friction between the arc-shaped block and the inner wall of the cleaning roller generates heat. When the machine stops or the rolling process is interrupted, the flywheel drives the second rotating shaft to decelerate. When the arc-shaped block rotates to the top, due to insufficient speed, the centrifugal force decreases. Under the combined action of gravity and the elastic force of the second spring, the second spring stretches and drives the limiting plate to move closer to the center of the centrifugal shell. The limiting plate drives the connecting column to move closer to the center of the centrifugal shell. The connecting column drives the arc-shaped block to move closer to the center of the centrifugal shell. The arc-shaped block separates from the inner wall of the cleaning roller. When the arc-shaped block rotates to the bottom, under the combined action of gravity and centrifugal force, the arc-shaped block strikes the inner wall of the cleaning roller, causing the cleaning roller to vibrate and causing the adhering impurities to detach from the surface of the cleaning roller.

[0012] The recycling device includes a housing mounted between two side plates. Friction blocks are installed at the bottom of the housing, and air distribution holes are installed on the housing. A main air vent is installed at the top of the housing, and a filter plate is installed inside the main air vent. A centrifugal fan is mounted on the base. The main air vent and the centrifugal fan are connected via a pipe, and the centrifugal fan is connected to the control system. When the cleaning roller rotates, the friction between the brush and the friction blocks generates static electricity. The friction between the arc-shaped block and the inner wall of the cleaning roller generates heat, increasing the amount of static electricity generated. This static electricity attracts impurities, triggering the centrifugal fan to start, creating negative pressure at the air distribution holes. Simultaneously, the generated heat also accelerates the release of static electricity, making it easier for impurities to detach from the air distribution holes and be drawn into the housing.

[0013] The correction device includes a lower plate mounted on a base. An upper plate is mounted on one side of the lower plate, and a lower roller and an upper roller are rotatably mounted on the upper plate, with the upper roller positioned above the lower roller. The upper roller is conical. During transport, if the steel deviates towards the narrower end of the upper roller, more of the steel will contact the narrower end of the upper roller, where the linear speed is slower. This results in less forward friction on the deviated side and more forward friction on the other side. This difference in friction creates a torque that forces the steel to move towards the wider end with the faster linear speed, automatically pulling the steel back to the center position, and vice versa, achieving an automatic correction effect.

[0014] The outer surface of the cleaning roller is equipped with a brush, and the friction block is made of rubber.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention employs tension adjustment technology. When the strain gauge sensor detects that the tension exceeds the preset threshold, the roll gap of the rolling mill is finely adjusted in a timely manner to reduce the tensile force on the steel, effectively avoiding rolling defects caused by excessive tension, and maintaining uniform stress on the strip steel, thereby significantly improving the yield and surface quality of high-nickel stainless steel.

[0017] 2. This invention employs automatic cleaning technology. Before rolling begins, an electrostatic adsorption device is used to pre-treat the surface of the raw materials, effectively adsorbing and removing dust, impurities, and fine metal particles adhering to the raw materials. This prevents these foreign objects from being pressed into the material during rolling, thus causing scratches, inclusions, or surface defects that affect the quality and performance of the finished product. At the same time, when the equipment is stopped or the rolling process is interrupted, the impurities and metal particles adsorbed on the surface of the device can be automatically removed, ensuring that the equipment maintains good adsorption capacity and cleaning efficiency for the next use.

[0018] 3. The present invention adopts automatic correction technology. Before the raw material enters the rolling zone through the conveying device, the conical roller can automatically adjust its rotation angle and pressure when the transport is off track, so that the raw material gradually returns to the correct conveying path, thereby achieving continuous and stable correction control and avoiding uneven rolling thickness, edge waviness or plate shape defects caused by incorrect position.

[0031] The rolling apparatus 6 includes a frame 61 mounted on a base 1. The frame 61 has a groove containing a first mounting plate 62 and a tension device 65.

The strain gauge sensor is connected to the control system. The first connecting shaft 4 drives the third coupling to rotate, which in turn drives the first roll 63 to rotate. The first roll 63 then drives the first gear 64 to rotate.

[0032] The tension device 65 includes a second mounting plate 651, which slides within a groove. A sliding groove is provided on the second mounting plate 651, and a slider 652 is slidably mounted within the sliding groove. A second roller 655 is rotatably mounted within the slider 652. A fourth coupling is mounted on one side of the second roller 655 and is mounted on a second connecting shaft 5.

A hydraulic cylinder 654 is mounted at the lower end of the sliding groove, and the cylinder rod of the hydraulic cylinder 654 is mounted on the slider 652. The hydraulic cylinder 654 is connected to the control system. The second connecting shaft 5 drives the fourth coupling to rotate, and the fourth coupling drives the second roller 655 to rotate. When the strain sensor detects that the tension is too high, the control system controls the hydraulic cylinder 654 to start. The cylinder rod of the hydraulic cylinder 654 extends and drives the slider 652 to slide in the sliding groove. The slider 652 slides towards the elastic damper 653. The slider 652 drives the second roller 655 to slide towards the elastic damper 653. The elastic damper 653 reduces the vibration when the slider 652 moves.

[0033] The pressing device 67 includes a second motor 671, which is mounted on a support plate 66.

The worm gear 672 drives the worm wheel 674 to rotate, which in turn drives the lead screw to rotate. The lead screw drives the lower nut 676 to slide on the lead screw. The lower nut 676 slides away from the worm wheel 674, which in turn drives the second mounting plate 651 to slide away from the worm wheel 674 until it slides to the predetermined position. The lower nut 676 then drives the pressure plate 675 to move away from the worm wheel 674. The pressure plate 675 presses on the first spring 677, which can balance the load and eliminate the weight of the roll.

[0034] The cleaning device 7 includes a base plate 71, which is mounted on a base 1. Side plates 72 are mounted on the base plate 71. A transmission device 73 is mounted on one side of the side plates 72. A cleaning roller 74 is rotatably mounted between the two side plates 72. A flywheel 76 is rotatably mounted on the other side of the side plates 72. The flywheel 76 is mounted on the transmission device 73. A recycling device 75 is mounted above the cleaning roller 74 and is located between the two side plates 72.

[0035] The transmission device 73 includes a second gear 731, a first cylinder mounted on a side plate 72, a third gear 732 mounted on the first cylinder, the second gear 731 mounted on one side of the third gear 732, a belt mounted on the outer side of the first gear 731 and the second gear 732, a fourth gear 733 and a first bevel gear 734 mounted on the cleaning roller 74, the third gear 732 and the fourth gear 733 meshing, a cross plate mounted on the side plate 72, a second cylinder and a support frame mounted on the cross plate, and a belt mounted on the second cylinder. A second bevel gear, a first rotating shaft 737 is rotatably mounted on a support frame, a third bevel gear 735 is mounted on the first rotating shaft 737, the first bevel gear 734 meshes with the second bevel gear, the second bevel gear and the third bevel gear 735 mesh, a centrifugal clutch is mounted on the first rotating shaft 737, a second rotating shaft 736 is rotatably mounted inside the cleaning roller 74, the centrifugal clutch is installed inside the second rotating shaft 736, a flywheel 76 is mounted on the second rotating shaft 736, and a centrifugal device 738 is mounted on the second rotating shaft 736. The first gear 64 drives the belt to rotate, the belt drives the second gear 731 to rotate, the second gear 731 drives the third gear 732 to rotate, the third gear 732 drives the fourth gear 733 to rotate, the fourth gear 733 drives the cleaning roller 74 to rotate, the cleaning roller 74 drives the first bevel gear 734 to rotate, the first bevel gear 734 drives the second bevel gear to rotate, the second bevel gear drives the third bevel gear 735 to rotate, the third bevel gear 735 drives the first rotating shaft 737 to rotate, the first rotating shaft 737 drives the centrifugal clutch to rotate, the centrifugal clutch engages, the centrifugal clutch drives the second rotating shaft 736 to rotate, the second rotating shaft 736 drives the flywheel 76 and the centrifugal device 738 to rotate, the flywheel 76 stores kinetic energy, when the machine stops or the rolling process is interrupted, the first motor 2 stops, causing the first rotating shaft 737 to stop rotating, the centrifugal clutch disengages, the flywheel 76 releases kinetic energy to drive the second rotating shaft 736 to decelerate and rotate.

[0036] The centrifuge device 738 includes a centrifuge housing 7381, which is mounted on a second rotating shaft 736. A centrifuge tank is provided on the centrifuge housing 7381. A limit plate 7382 is slidably installed in the centrifuge tank. A connecting column 7383 is installed on one side of the limit plate 7382. An arc-shaped block 7384 is installed on one side of the connecting column 7383. A second spring 7385 is sleeved on the outside of the connecting column 7383. One end of the second spring 7385 is installed on the limit plate 7382, and the other end of the second spring 7385 is installed on the centrifuge housing 7381.

[0037] The second rotating shaft 736 drives the centrifugal outer shell 7381 to rotate. Under the action of centrifugal force, the connecting column 7383 moves away from the center of the centrifugal outer shell 7381. The connecting column 7383 drives the arc-shaped block 7384 to move away from the center of the centrifugal outer shell 7381. The arc-shaped block 7384 presses against the inner wall of the cleaning roller 74. The friction between the arc-shaped block 7384 and the inner wall of the cleaning roller 74 generates heat. When the machine stops or the rolling process is interrupted, the flywheel 76 drives the second rotating shaft 736 to rotate at a reduced speed. When the arc-shaped block 7384 rotates to the top, due to insufficient speed, the centrifugal force decreases. Under the combined force of gravity and the elastic force of the second spring 7385, the centrifugal force decreases. Under the same action, the second spring 7385 stretches and drives the limiting plate 7382 to move closer to the center of the centrifugal shell 7381. The limiting plate 7382 drives the connecting column 7383 to move closer to the center of the centrifugal shell 7381. The connecting column 7383 drives the arc block 7384 to move closer to the center of the centrifugal shell 7381. The arc block 7384 separates from the inner wall of the cleaning roller 74. When the arc block 7384 rotates to the bottom, under the combined action of gravity and centrifugal force, the arc block 7384 strikes the inner wall of the cleaning roller 74, causing the cleaning roller 74 to vibrate and causing the adhering impurities to detach from the surface of the cleaning roller 74.

[0038] The recycling device 75 includes a housing 751, which is installed between two side plates 72. A friction block 752 is installed below the housing 751. A distribution air hole 753 is installed on the housing 751, and a main air hole 754 is installed above the housing 751. A filter plate is installed inside the main air hole 754. A centrifugal fan is installed on the base 1. The main air hole 754 and the centrifugal fan are connected by a pipe. A brush is installed on the outer surface of the cleaning roller 74. The friction block 752 is made of rubber. The centrifugal fan is connected to the control system. When the cleaning roller 74 rotates, the brush and the friction block 752 generate static electricity through friction. The arc-shaped block 7384 generates heat through friction with the inner wall of the cleaning roller 74, increasing the amount of static electricity generated. Static electricity attracts impurities, controls the centrifugal fan to start, and creates a negative pressure at the distribution air hole 753. At the same time, the heat generated also accelerates the release of static electricity, making it easier for impurities to detach from the distribution air hole 753 and be attracted into the housing 751.

[0039] The correction device 8 includes a lower plate 81 mounted on a base 1. An upper plate 82 is mounted on one side of the lower plate 81. A lower roller 83 and an upper roller 84 are rotatably mounted on the upper plate 82, with the upper roller 84 positioned above the lower roller 83 and being conical. During transport, if the steel deviates towards the narrower end of the upper roller 84, more of the steel will contact the narrower end of the upper roller 84 where the linear speed is slower. This results in a smaller forward friction force on the deviated side and a larger forward friction force on the other side. This difference in friction creates a torque that forces the steel to move towards the wider end with the faster linear speed, automatically pulling the steel back to the center position, and vice versa, achieving an automatic correction effect.

[0040] Working principle of the invention:

[0041] Before rolling, the second motor 671 is started. The output shaft of the second motor 671 drives the rotating rod to rotate, which in turn drives the worm gear 672 to rotate. The worm gear 672 drives the worm wheel 674 to rotate, which in turn drives the lead screw to rotate. The lead screw drives the lower nut 676 to slide on the lead screw. The lower nut 676 slides away from the worm wheel 674, which in turn drives the second mounting plate 651 to slide away from the worm wheel 674 until it slides to the predetermined position. The lower nut 676 then drives the pressure plate 675 to move away from the worm wheel 674. The pressure plate 675 presses on the first spring 677, which can balance the load and eliminate the weight of the roll.

[0042] After the roll gap adjustment is completed, the first motor 2 is started. The first motor 2 drives the gear in the gearbox 3 to rotate. The gearbox 3 drives the first coupling and the second coupling to rotate. The first coupling drives the first connecting shaft 4 to rotate. The second coupling drives the second connecting shaft 5 to rotate. The first connecting shaft 4 drives the third coupling to rotate. The third coupling drives the first roll 63 to rotate. The first roll 63 drives the first gear 64 to rotate. The second connecting shaft 5 drives the fourth coupling to rotate. The fourth coupling drives the second roll 655 to rotate. When the strain sensor detects that the tension is too high, the control system controls the hydraulic cylinder 654 to start. The cylinder rod of the hydraulic cylinder 654 extends and drives the slider 652 to slide in the sliding groove. The slider 652 slides towards the elastic damper 653. The slider 652 drives the second roll 655 to slide towards the elastic damper 653. The elastic damper 653 reduces the vibration of the slider 652 when it moves.

[0043] During steel transportation, if the steel deviates from the finer end of the upper roller 84, more of the steel will come into contact with the thinner end of the upper roller 84, where the linear speed is slower. This results in a smaller forward friction force on the deviated side and a larger forward friction force on the other side. This difference in friction creates a torque that forces the steel to move towards the thicker end with the faster linear speed, automatically pulling the steel back to the center position, and vice versa, achieving an automatic correction effect.

[0044] Before steel rolling, the first gear 64 drives the belt to rotate, the belt drives the second gear 731 to rotate, the second gear 731 drives the third gear 732 to rotate, the third gear 732 drives the fourth gear 733 to rotate, the fourth gear 733 drives the cleaning roller 74 to rotate, the cleaning roller 74 drives the first bevel gear 734 to rotate, the first bevel gear 734 drives the second bevel gear to rotate, the second bevel gear drives the third bevel gear 735 to rotate, the third bevel gear 735 drives the first rotating shaft 737 to rotate, the first rotating shaft 737 drives the centrifugal clutch to rotate, the centrifugal clutch engages, the centrifugal clutch drives the second rotating shaft 736 to rotate, the second rotating shaft 736 drives the flywheel 76 and the centrifugal device 738 to rotate, the flywheel 76 stores kinetic energy, and the second rotating shaft 736 drives... The centrifugal shell 7381 rotates, and the connecting column 7383 moves away from the center of the centrifugal shell 7381 under the action of centrifugal force. The connecting column 7383 drives the arc block 7384 to move away from the center of the centrifugal shell 7381. The arc block 7384 presses on the inner wall of the cleaning roller 74. The friction between the arc block 7384 and the inner wall of the cleaning roller 74 generates heat. The friction between the brush and the friction block 752 generates static electricity. The friction between the arc block 7384 and the inner wall of the cleaning roller 74 generates heat, which increases the amount of static electricity generated. Static electricity adsorbs impurities, controls the centrifugal fan to start, and creates negative pressure at the air distribution hole 753. At the same time, the heat generated also accelerates the static electricity release rate, making it easier for impurities to detach and be adsorbed by the air distribution hole 753. The impurities are sucked into the shell 751.

[0045] When the machine stops or the rolling process is interrupted, the first motor 2 stops, causing the first rotating shaft 737 to stop rotating. The centrifugal clutch disengages, and the flywheel 76 releases kinetic energy to drive the second rotating shaft 736 to decelerate. When the arc-shaped block 7384 rotates to the top, due to insufficient speed, the centrifugal force decreases. Under the combined action of gravity and the elastic force of the second spring 7385, the second spring 7385 stretches, causing the limiting plate 7382 to move closer to the center of the centrifugal housing 7381. The limiting plate 7382 then drives the connecting column 7383 to move closer to the center of the centrifugal housing 7381. As the centrifugal shell 7381 moves towards the center, the connecting column 7383 drives the arc-shaped block 7384 to move closer to the center of the centrifugal shell 7381. The arc-shaped block 7384 separates from the inner wall of the cleaning roller 74. When the arc-shaped block 7384 rotates to the bottom, under the combined action of gravity and centrifugal force, the arc-shaped block 7384 strikes the inner wall of the cleaning roller 74, causing the cleaning roller 74 to vibrate. This causes the adhering impurities to detach from the surface of the cleaning roller 74, achieving a self-cleaning effect and ensuring that the equipment maintains good adsorption capacity and cleaning efficiency in the next use.
