Description

Technical Field

[0001] This invention relates to the field of rolling technology, specifically to a strip coil rolling mill and method with a front tension adjustment mechanism. Background Technology

[0002] A strip rolling mill is a mechanical device that uses pressure to press strip steel to form strip steel of a specific thickness. During the rolling process, lubricating oil needs to be applied to the surface of the strip steel to make the contact between the strip steel and the rolls smoother, thereby improving the rolling effect of the rolls on the strip steel.

[0003] The background art of the intelligent strip steel rolling device for preventing stress deformation, disclosed in CN117161092B, addresses the following problem: When using coiled steel plates, strip steel rolling devices are needed to flatten them, remove their irregular internal stress, and make them into flat plates; however, it is impossible to eliminate the stress generated by unidirectional rolling during the rolling operation of the strip steel, which makes the strip steel prone to deformation during rolling.

[0004] Based on existing technologies, the following problems exist:

[0005] Existing strip rolling mills typically apply lubricating oil to both sides of the strip during rolling by spraying. However, this results in insufficient contact between the lubricating oil and the strip. Furthermore, excessive spraying leads to oil dripping directly down the strip, wasting oil and reducing lubrication effectiveness. Conversely, insufficient spraying results in poor lubrication, impacting subsequent rolling operations. Additionally, cleaning the strip surface before spraying is difficult, as impurities like iron filings can hinder oil contact, affecting wetting and subsequent rolling performance. While the aforementioned application combines spraying and roller coating for strip lubrication, the amount of lubricating oil applied during roller coating is difficult to adjust based on actual rolling requirements. The oil output can only be adjusted by controlling the force applied to prevent strip slack, which is insufficient. To address these issues, a strip coil rolling mill and method with a pre-tension adjustment mechanism are proposed. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention provides a strip coil rolling mill and method with a front tension adjustment mechanism, which facilitates the adjustment of the amount of lubricating oil applied according to actual rolling requirements, so that the lubricating oil and the strip can be in full contact. Furthermore, it facilitates the cleaning of the strip surface before spraying the lubricating oil, avoiding the influence of impurities such as iron filings on the strip surface on the contact between the lubricating oil and the strip, thereby improving the wetting effect of the lubricating oil and the subsequent rolling effect.

[0038] The present invention also provides a method of using a strip coil rolling mill with a front tension adjustment mechanism. The method, using the aforementioned strip coil rolling mill with a front tension adjustment mechanism, includes the following steps:

[0039] S1: Before the strip is conveyed to the rolling mechanism, the top and bottom of the strip are coated with lubricating oil by the coating mechanism in order to roll the strip in the future.

[0040] S2: When applying lubricating oil to the surface of the strip steel, the cleaning mechanism and the coating mechanism are linked to clean the strip steel of the part to be coated with lubricating oil, removing debris and impurities from the surface of the strip steel.

[0041] This invention provides a strip coil rolling mill and method with a front tension adjustment mechanism. Compared with the prior art, it has the following advantages:

[0042] 1. This invention applies lubricating oil to both sides of the strip steel to be rolled using a coating mechanism, and allows for easy adjustment of the amount of lubricating oil applied according to actual rolling requirements, thereby improving the strip steel rolling effect. By linking the cleaning mechanism with the coating mechanism, it is convenient to clean the strip steel to be coated with lubricating oil, which is conducive to full contact between the lubricating oil and the strip steel, improving the effect of lubricating oil coating, and avoiding the impact of debris and other impurities on the subsequent rolling effect.

[0043] 2. This invention adjusts the height of the roller, coating component, and spraying component by coordinating the adjustment and limiting components, thereby adjusting the degree of compression between the strip and the cotton wiping plate. The pressure sensor monitors the compression force to control the amount of lubricating oil applied, facilitating actual lubrication. By setting multiple coating components arranged at intervals, the lubricating oil is evenly absorbed into the cotton wiping plate, thus facilitating the even coating of lubricating oil on the surface of the strip, improving the lubrication effect, and thereby improving the rolling effect.

[0044] 3. The present invention uses a coating component to uniformly coat the surface of the strip steel, and a spraying component to spray the lubricating oil onto the surface of the strip steel. This allows for easy adjustment of the amount of lubricating oil according to the rolling conditions, thereby improving the rolling effect. Furthermore, the spraying component and the coating component are linked together for easy adjustment according to actual conditions. By setting the strip steel at an angle, the coating mechanism and the cleaning mechanism are perpendicular to the conveying direction of the strip steel, which facilitates the actual application of lubricating oil and cleaning.

[0045] 4. The present invention links the cleaning mechanism and the coating mechanism, and the height of the scraper can be adjusted independently, which facilitates the scraper to clean the strip steel, improves the cleaning effect, and makes the roller press against the strip steel, which facilitates the reciprocating movement of the push plate, thereby cleaning the impurities accumulated on the inner side of the scraper, which is convenient for long-term cleaning.

[0046] 5. The present invention uses a tensioning mechanism to transport the strip steel in an S-shape through two tensioning rollers. When the strip steel is transported through the two tensioning rollers, it is transported in the opposite direction to the uncoiling of the uncoiling machine, so as to tighten the strip steel. This tensions the strip steel before rolling, so as to better match the tension during rolling and improve the rolling effect. Attached Figure Description

[0072] 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.

[0073] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A strip steel coil rolling mill with a front tension adjustment mechanism includes a frame 1 and a rolling mechanism 2 located inside the frame 1 for rolling the strip steel. The rolling mechanism 2 typically includes rolls, a drive motor for rotating the rolls, and a height adjustment mechanism for adjusting the roll height. The height of the rolls is adjusted by the height adjustment mechanism, and the rolls are driven to rotate by the drive motor to roll the strip steel that enters between the two rolls. During rolling, an uncoiling machine and a coiling machine (not shown in the figure) are usually installed on both sides of the frame 1 for unwinding and coiling the strip steel. This allows the strip to pass between two rolls and facilitates coiling of the strip after rolling. The above are all existing technologies and will not be elaborated here. It also includes a coating mechanism 6 for applying lubricating oil to the strip and a cleaning mechanism 4 for cleaning impurities on the surface of the strip, which is set inside the frame 1. A tensioning mechanism 3 for tensioning the strip is set inside the frame 1 and on the side of the coating mechanism 6 away from the rolling mechanism 2. The position of the strip output by the tensioning mechanism 3 is above the position of the strip input by the rolling mechanism 2, so that the strip is tilted.

[0074] The tensioning mechanism 3 includes two tensioning rollers 31 spaced apart and connected by a drive mechanism. Both tensioning rollers 31 are rotatably connected to the frame 1. Gears are fixedly fitted on the side walls of the two tensioning rollers 31 located outside the frame 1, and the gears mesh with each other. A servo motor 32 is fixedly installed on the outside of the frame 1. The output shaft of the servo motor 32 is fixedly connected to the end of one of the tensioning rollers 31 located outside the frame 1 through a coupling, so as to drive the two tensioning rollers 31 to rotate. After the strip is unwound by the uncoiler, it is conveyed in an S-shape by the two tensioning rollers 31. By driving the tensioning rollers 31 to rotate by the servo motor 32, the strip is conveyed in the opposite direction to the uncoiler when it is conveyed by the two tensioning rollers 31, so as to tighten the strip. This tensions the strip before rolling, so as to better match the tension during rolling and improve the rolling effect.

[0075] Example 2: Please refer to Figure 5 , Figure 6 and Figure 10 The difference between this embodiment and Embodiment 1 lies in the fact that the coating mechanism 6 includes:

[0076] Roller body 64 is movably disposed on the top and bottom of strip steel, and has a hollow design in the middle of the interior to store lubricating oil. Cotton wiping plates 65 are fixedly provided on the sides of roller body 64 that are close to each other. Coating components 67 for supplying lubricating oil to cotton wiping plates 65 are provided at intervals inside roller body 64.

[0077] Please see Figure 10 , Figure 11 and Figure 12 The coating component 67 includes:

[0078] The base 671 is fixedly mounted on the inner wall of the roller body 64. A plug 674 is fitted on the bottom of the base 671, and the plug 674 is designed in the shape of an inverted frustum. The amount of lubricating oil discharged from the base 671 can be adjusted by adjusting the height of the plug 674. A rod 673 extending to the top of the base 671 is fixedly mounted on the top of the plug 674. A spray assembly 68 for increasing the amount of lubricating oil discharged is provided on the side wall of the rod 673 located at the top of the base 671.

[0079] Coating component 67 also includes:

[0080] The base 676 is fixedly mounted on the top of the cotton wiping plate 65. The cotton wiping plate 65 is made of oil-guiding material, and the top of the cotton wiping plate 65 is in contact with the outer wall of the roller body 64. The top of the base 676 is provided with a first oil guiding groove 675 arranged in a ring array.

[0081] The second oil guide groove 672 is arranged in a ring array on the side wall of the base 671. The upper part of the base 671 is hollow, and the hollow part of the base 671 is connected to the second oil guide groove 672 so that the lubricating oil in the roller 64 can enter the base 671.

[0082] The bottom of the base 671 has a frustum-shaped through groove for fitting the plug 674, and it communicates with the hollow part of the base 671 so as to cooperate with the plug 674 and adjust the amount of lubricating oil discharged from the base 671.

[0083] A first spring is fitted on the side wall of the rod 673 and between the top of the plug 674 and the top inner wall of the base 671;

[0084] The top of the base 671 has a first through hole for mounting the rod 673.

[0085] In practice, the cotton wiping plate 65, through the cooperation of the adjusting component 63 and the limiting component 61, contacts the top and bottom of the strip steel, thereby coating the lubricating oil on the contact surface between the roll and the strip steel. During the coating process, the lubricating oil is delivered to the hollow part inside the roll body 64 through the external pipe. The lubricating oil enters the frustum-shaped channel through the second oil guide groove 672 and the hollow part of the base 671, flows to the top of the base 676 through the gap between the frustum-shaped channel and the plug 674, and then is discharged into the cotton wiping plate 65 through the first oil guide groove 675, thereby coating the surface of the strip steel with lubricating oil to improve the rolling effect.

[0086] By adjusting the height of the roller 64 and the cotton wiping plate 65, the degree of compression of the strip steel onto the cotton wiping plate 65 is adjusted, thereby adjusting the degree of compression of the base 676 onto the plug 674, thereby adjusting the height of the plug 674, and adjusting the amount of lubricating oil left outside the base 671 through the gap between the plug 674 and the frustum-shaped through groove, thereby adjusting the amount of lubricating oil coated on the surface of the strip steel, which is convenient to adjust according to the actual rolling conditions and improve the rolling effect of the strip steel.

[0087] The second oil guide groove 672 facilitates the entry of lubricating oil into the base 671 without affecting the movement of the rod 673 and the plug 674. The first oil guide groove 675 facilitates the entry of lubricating oil into the cotton wiping plate 65, which is convenient for subsequent application of lubricating oil to the surface of the strip. Furthermore, the spaced coating components 67 and spraying components 68 facilitate the uniform adsorption of lubricating oil in the cotton wiping plate 65, thereby making it easier to evenly apply the lubricating oil to the surface of the strip, improving the lubrication effect and thus improving the rolling effect.

[0088] The first spring provides elastic support to the plug 674, ensuring that the plug 674 always tends to move downwards. This allows the plug 674 to be pressed tightly against the frustum-shaped through groove when no lubricating oil is applied, thus preventing the lubricating oil from flowing downwards and avoiding waste of lubricating oil.

[0089] Please see Figure 12 , Figure 13 and Figure 14 The injection assembly 68 includes:

[0090] An oil guide seat 681 is fixedly disposed on the outer wall of the roller body 64 and extends into the roller body 64. The end of the oil guide seat 681 located outside the roller body 64 faces the rolling mechanism 2. A movable groove 685 is provided on the side wall of the end of the oil guide seat 681 located inside the roller body 64. The right inner wall of the movable groove 685 is arc-shaped. An oil guide hole 682 communicating with the movable groove 685 is provided inside the oil guide seat 681.

[0091] The stop lever 683 is fitted inside the movable groove 685, and the side wall of the stop lever 683 fits against the arc-shaped inner wall of the movable groove 685, so as to adjust the opening or closing of the oil guide hole 682 through the stop lever 683;

[0092] The connecting plate 684 is fixedly sleeved on the side wall of the rod 673 located outside the base 671, and the side of the connecting plate 684 away from the rod 673 is fixedly connected to the stop bar 683.

[0093] The injection assembly 68 also includes:

[0094] A sealing ring 686 is fixedly sleeved on the side wall of the stop bar 683 and arranged at intervals, and is located at the bottom and top of the connecting plate 684 respectively. The top of the stop bar 683 extends to the top of the oil guide seat 681. The top of the oil guide seat 681 is provided with a second through hole for sleeved on the stop bar 683. The inner side wall of the oil guide seat 681 is provided with a placement groove. The inner wall of the placement groove is fixedly sleeved with a ball seat 689. The inner wall of the ball seat 689 is sleeved with a ball body 688 that abuts against the stop bar 683.

[0095] A collar 687 is fitted onto the side wall of the ball body 688 and is located on the side of the ball seat 689 away from the stop lever 683. A second spring is fixedly provided on the inner wall of the groove, and the second spring is fixedly connected to the side of the collar 687 away from the ball seat 689.

[0096] In practical implementation, when a sudden situation requires more lubricating oil, the plug 674 is moved upward to the maximum extent. At this time, a large amount of lubricating oil is discharged into the cotton wiping plate 65 through the base 671, increasing the discharge volume of lubricating oil. At the same time, the plug 674 drives the rod 673, the connecting plate 684 and the stop rod 683 to move upward, so that the stop rod 683 is misaligned with the oil guide hole 682, so that the lubricating oil enters the oil guide hole 682 through the moving groove 685 and is sprayed onto the surface of the strip steel through the oil guide hole 682, further increasing the discharge volume of lubricating oil, which is convenient for actual rolling use. In addition, since the strip steel is conveyed at an incline through the tensioning mechanism 3 and the rolling mechanism 2, it is convenient for the lubricating oil to flow between the roll and the strip steel, thereby improving the lubrication effect and improving the rolling effect.

[0097] The coating component 67 evenly coats the surface of the strip with lubricating oil, and the spraying component 68 sprays lubricating oil onto the surface of the strip. This allows for easy adjustment of the amount of lubricating oil according to the rolling conditions, thereby improving the rolling effect. Furthermore, the spraying component 68 and the coating component 67 are linked together for easy adjustment according to actual conditions.

[0098] The ball bearing 688 rotates within the ball bearing seat 689 to reduce the friction between the shift lever 683 and the oil guide seat 681, thereby improving the smoothness of the shift lever 683's movement. The second spring provides elastic support for the ball bearing 688, allowing the side wall of the shift lever 683 to fit against the oil guide hole 682, thus improving the sealing effect of the shift lever 683 on the oil guide hole 682. The spaced sealing rings 686 further enhance the sealing effect of the shift lever 683 on the oil guide hole 682. The collar 687 supports the connection between the second spring and the ball bearing 688, facilitating better action of the second spring on the ball bearing 688 and improving the stability of the elastic support for the ball bearing 688.

[0099] Because the strip is set at an angle, the coating mechanism 6 and the cleaning mechanism 4 are perpendicular to the conveying direction of the strip, which facilitates the actual application of lubricating oil and cleaning. Therefore, it is convenient to spray lubricating oil downward at the oil guide hole 682, and to make the lubricating oil flow between the roll and the strip.

[0100] Please see Figure 6 , Figure 7 , Figure 8 and Figure 9 The coating mechanism 6 also includes:

[0101] Mounting base 62 is fixedly disposed on the front and back of frame 1. A movable through groove 66 is provided on the front of each mounting base 62. A limiting component 61 for limiting the movement of roller 64 is provided on the inner wall of the movable through groove 66. Adjusting components 63 for adjusting the height of roller 64 are provided at the upper and lower ends of the mounting base 62. The limiting component 61 includes:

[0102] The first slide groove 612 is formed on both sides of the inner wall of the movable through groove 66. The first slide groove 612 is filled with a first slider, and the first slider is fixedly connected to both ends of the outer wall of the roller body 64.

[0103] The guide rod 611 is sleeved on the side wall of the first slider, and the two ends of the guide rod 611 are fixedly connected to the top inner wall and the bottom inner wall of the first slide groove 612, respectively. A third spring is sleeved on the side wall of the guide rod 611 between the first sliders.

[0104] Adjustment component 63 includes:

[0105] A mounting groove 631 is formed inside the upper part of the mounting base 62. A first electromagnet 633 is fixedly installed on the top of the inner wall of the mounting groove 631. A second electromagnet 634 is sleeved on the inner wall of the mounting groove 631. The sides of the second electromagnet 634 and the first electromagnet 633 that are close to each other are the same magnetic poles. A pressure sensor 635 is fixedly installed on the bottom inner wall of the mounting groove 631. A fourth spring is sleeved on the inner wall of the mounting groove 631 between the pressure sensor 635 and the second electromagnet 634. The first electromagnet 633, the second electromagnet 634 and the pressure sensor 635 are all designed in a ring shape.

[0106] The adjusting rod 632 is fixedly sleeved on the inner wall of the second electromagnet 634, and the top and bottom of the adjusting rod 632 extend along the inner walls of the first electromagnet 633 and the pressure sensor 635 to the top of the mounting base 62 and the moving through groove 66, respectively. One end of the adjusting rod 632 located in the moving through groove 66 is fixedly provided with a stop plate 636, and the stop plate 636 is arc-shaped to fit against the outer wall of the roller body 64.

[0107] In specific implementation, the first electromagnet 633 and the second electromagnet 634 are energized. Since the sides of the first electromagnet 633 and the second electromagnet 634 that are close to each other are the same magnetic poles, the repulsive force generated will drive the second electromagnet 634 to move along the inner wall of the mounting groove 631, thereby driving the adjusting rod 632 and the abutment plate 636 to move vertically, so as to limit the roller body 64 and adjust the height of the roller body 64, thereby adjusting the squeezing force of the cotton wiping plate 65 on the strip steel, and making it easy to adjust the amount of lubricating oil according to the actual rolling requirements.

[0108] By setting a pressure sensor 635 and a fourth spring, the second electromagnet 634 is able to squeeze the fourth spring and act on the pressure sensor 635 when it moves downward. The force value monitored by the pressure sensor 635 can be used to determine the downward position of the second electromagnet 634, so as to determine the amount of lubricating oil to be applied.

[0109] The first slider moves within the first groove 612 to limit the movement of the roller 64. The limiting effect is further improved by moving the first slider along the guide rod 611, and the third spring is also limited. This allows the third spring to provide elastic support for the roller 64, and prevents the cotton wiping plate 65 from being squeezed against the strip when no lubricating oil is applied, which is convenient for practical use.

[0110] Example 3: Please refer to Figure 15 , Figure 16 and Figure 17 The technical difference between this embodiment and embodiment two is that the cleaning mechanism 4 includes:

[0111] The connecting seat 42 is fixedly disposed on the side of the first slider away from the roller 64 and located on the outside of the frame 1. The outer side of the mounting seat 62 is provided with a first through groove communicating with the first slide groove 612, and the inner wall of the first through groove is sleeved on the side wall of the connecting seat 42. The inner side of the connecting seat 42 is provided with a scraper 43. The scraper 43 is designed in a bent shape so that the side of the scraper 43 away from the rolling mechanism 2 forms an inner groove 45. Both sides of the frame 1 and the bottom of the scraper 43 are provided with a drain trough 5.

[0112] Push plate 491 is sleeved on the inner wall of inner groove 45. A second slide groove 49 is provided at the top of inner groove 45. A second slider is placed inside the second slide groove 49. The bottom of the second slider is fixedly connected to the top of push plate 491.

[0113] The reciprocating screw 48 is rotatably mounted on the side wall of the connecting seat 42. The side wall of the reciprocating screw 48 is threadedly connected to a threaded tube. The outer wall of the threaded tube is fixedly provided with an installation plate, and the installation plate is fixedly connected to the push plate 491. The inner wall of the inner groove 45 is provided with a second through groove for fitting the installation plate.

[0114] Roller 44 is located on the side of scraper 43 near roller body 64. A rotating rod is fixedly sleeved on the inner wall of roller 44. The two ends of the side wall of the rotating rod are rotatably connected to the connecting seat 42, and the rotating rod is drivenly connected to the reciprocating screw 48.

[0115] Cleanup agency 4 also includes:

[0116] The top plate 41 is fixedly installed on the inner side of the connecting seat 42. The bottom of the top plate 41 is fixedly provided with a third electromagnet 46, and the top of the scraper 43 is fixedly provided with a fourth electromagnet 47. The sides of the fourth electromagnet 47 and the third electromagnet 46 that are close to each other are the same magnetic poles.

[0117] The third slide groove 492 is located inside the connecting seat 42. The third slide groove 492 contains a third slider, which is fixedly connected to the scraper 43.

[0118] In practical implementation, when the height of the roller 64 is adjusted by adjusting component 63, the first slider drives the connecting seat 42 to move along the first through groove, thereby making the connecting seat 42 and the roller 64 move synchronously. This facilitates the initial adjustment of the position of the scraper 43 to better suit strips of different thicknesses. Furthermore, the repulsive force generated by the third electromagnet 46 and the fourth electromagnet 47 after energization drives the scraper 43 downwards, so that the bottom of the scraper 43 abuts against the top of the strip. This facilitates scraping the strip during conveying, removing residual impurities from the strip surface, preventing subsequent interference with the contact between the lubricating oil and the strip, and improving lubrication and rolling effects. Additionally, the roller 44... As the connecting seat 42 moves downward, the roller 44 presses against the surface of the strip steel, thereby driving the roller 44 to rotate during the strip steel conveying process. This, in turn, drives the rotating rod to rotate. Since the rotating rod is connected to the reciprocating screw 48, the rotating screw 48 drives the mounting plate and push plate 491 to move along the second slide groove 49 and the second through groove during rotation. This pushes the impurities accumulated in the groove 45 of the scraper 43. Since the connecting seat 42 is located outside the frame 1, the accumulated impurities are pushed outside the frame 1 during the reciprocating movement of the push rod and discharged along the drain trough 5. This facilitates the cleaning of the impurities pushed into the groove 45 of the scraper 43, making it convenient for long-term strip steel cleaning.

[0119] The first electromagnet 633 and other electronic devices of the present invention are all connected to an external power supply via wires, which facilitates actual control and use. The lubricating oil external oil circuit of the present invention is used to deliver lubricating oil into the roller body 64. The above are all prior art and will not be described in detail here.

[0120] This invention also provides a method for using a strip coil rolling mill with a front tension adjustment mechanism. The method includes the following steps:

[0121] S1: Before the strip is conveyed to the rolling mechanism 2, the top and bottom of the strip are coated with lubricating oil by the coating mechanism 6 for subsequent rolling. During the coating process, the height of the roller 64 and the cotton wiping plate 65 are adjusted by the cooperation of the adjusting component 63 and the limiting component 61 to apply lubricating oil to strips of different thicknesses. The adjusting mechanism also adjusts the tightness between the roller 64 and the strip, thereby causing the strip to squeeze the cotton wiping plate 65 through the reaction force. The amount of lubricating oil discharged through the cotton wiping plate 65 is adjusted by the coating component 67, which facilitates the adjustment of the amount of lubricating oil discharged according to the actual rolling situation, thereby improving the actual rolling effect. The coating component 67 cooperates with the spraying component 68. When the cotton wiping plate 65 moves upward to its maximum extent and can no longer move, the spraying mechanism sprays lubricating oil outward. The strip is conveyed at an angle to facilitate the flow of lubricating oil between the roll and the strip, thereby meeting the actual rolling requirements.

[0122] S2: When applying lubricating oil to the surface of the strip, the cleaning mechanism 4 and the coating mechanism 6 are linked to clean the strip of the part to be coated with lubricating oil, remove the debris and impurities on the surface of the strip, so that the lubricating oil can come into contact with the surface of the strip, improve the lubrication effect, and thus facilitate actual rolling use.
