Description

Technical Field

[0001] The invention relates to the technical field of rolling, in particular to a strip steel coil rolling mill with a front tension adjustment mechanism and a method thereof. Background Art

[0002] A strip rolling machine 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 roller smoother, thereby improving the effect of the roller on the strip steel rolling.

[0003] An intelligent strip rolling device for preventing stress deformation, with publication number CN117161092B, has the following problems raised in its background technology: when the rolled steel plates are in use, they need to be flattened using a strip rolling device to remove their irregular internal stresses and make them flat; and it is impossible to eliminate the stress generated by unidirectional rolling during the rolling operation of the strip, and thus this rolling method is very likely to cause deformation during the rolling of the strip.

[0004] Based on the existing technology, there are the following problems: When the existing strip steel rolling device applies lubricating oil during the rolling process, the lubricating oil is usually sprayed onto both sides of the strip steel by spraying, but this results in insufficient contact between the lubricating oil and the strip steel, and when the lubricating oil sprayed is large, it is easy to flow down directly after contacting the strip steel, wasting the lubricating oil and reducing the lubrication effect. If the lubricating oil sprayed is small, the lubrication effect is poor, thus affecting the subsequent rolling use, and it is not convenient to clean the surface of the strip steel before spraying the lubricating oil, and impurities such as iron filings attached to the surface of the strip steel affect the contact between the lubricating oil and the strip steel, thereby affecting the infiltration of the lubricating oil and the subsequent rolling effect. Referring to the above application documents, although the strip steel is lubricated by a combination of spraying and rolling, it is not convenient to adjust the amount of lubricating oil applied according to actual rolling needs during the rolling process, and the oil output can only be adjusted by the force to prevent the strip steel from slackening. There are certain shortcomings. In order to solve the above problems, a strip steel coil rolling mill and method with a front tension adjustment mechanism are proposed. Summary of the invention

A rod body 673 extending to the top of the base 671 is fixedly arranged on the top of the plug 674, and an injection assembly 68 for increasing the amount of lubricating oil discharged is arranged on the side wall of one end of the rod body 673 located at the top of the base 671.

[0026] The coating assembly 67 also includes: The base 676 is fixedly arranged on the top of the cotton wiping plate 65. The cotton wiping plate 65 is made of an oil-conducting 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 first oil-conducting grooves 675 arranged in a circular array. The second oil guide grooves 672 are opened in a circular array on the side wall of the base 671 . The inner upper end of the base 671 is hollow, and the hollow part of the base 671 is connected to the second oil guide grooves 672 to allow the lubricating oil in the roller body 64 to enter the base 671 .

[0027] The bottom of the base 671 is provided with a truncated cone-shaped through groove for sleeve-mounting the plug 674, and is communicated with the hollow part of the base 671 to cooperate with the plug 674 to adjust the amount of lubricating oil discharged from the base 671; A first spring is sleeved on the side wall of the rod body 673 and between the top of the plug 674 and the top inner wall of the base 671; A first through hole for sleeve mounting of the rod body 673 is defined at the top of the base 671 .

[0028] In specific implementation, the cotton wiping plate 65 contacts the top and bottom of the steel strip through the adjustment component 63 and the limit component 61, so that the lubricating oil is applied to the contact surface between the roller and the steel strip. In specific application, the lubricating oil is transported to the hollow inside the roller body 64 through the external pipeline, and the lubricating oil enters the truncated cone-shaped groove through the second oil guide groove 672 and the hollow part of the base 671, and flows to the top of the base 676 through the gap between the truncated cone-shaped groove and the plug 674, and then, it is discharged into the cotton wiping plate 65 through the first oil guide groove 675, so that the lubricating oil is applied to the surface of the steel strip to improve the rolling effect; By adjusting the height of the roller body 64 and the cotton wiping plate 65, the degree of compression of the steel strip on the cotton wiping plate 65 is adjusted, and the degree of compression of the base 676 on the plug 674 is adjusted, so as to adjust the height of the plug 674, and adjust the amount of lubricating oil remaining outside the base 671 through the gap between the plug 674 and the truncated cone-shaped through groove, so as to adjust the amount of lubricating oil applied to the surface of the steel strip, so as to facilitate adjustment according to the actual rolling conditions and improve the rolling effect of the steel strip; The second oil guide groove 672 is provided to facilitate the lubricating oil to enter the base 671 without affecting the movement of the rod 673 and the plug 674. The first oil guide groove 675 facilitates the lubricating oil to enter the cotton wiping plate 65, which is convenient for the subsequent coating of the lubricating oil on the surface of the steel strip. The coating components 67 and the spray components 68 are arranged at intervals, which facilitates the uniform absorption of the lubricating oil in the cotton wiping plate 65, thereby facilitating the uniform coating of the lubricating oil on the surface of the steel strip, thereby improving the lubrication effect and thus improving the rolling effect. The first spring is used to elastically support the plug 674, so that the plug 674 always has a tendency to move downward, so that when no lubricating oil is applied, the plug 674 is pressed tightly against the truncated cone-shaped groove, thereby preventing the lubricating oil from flowing downward and avoiding waste of the lubricating oil.

[0029] See also Fig.12 , Fig.13 and Fig.14 , the injection assembly 68 includes: The oil guide seat 681 is fixedly arranged 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. The side wall of the end of the oil guide seat 681 located inside the roller body 64 is provided with a movable groove 685, and the right inner wall of the movable groove 685 is designed in an arc shape. The inside of the oil guide seat 681 is provided with an oil guide hole 682 connected with the movable groove 685. The lever 683 is sleeved in the movable groove 685, and the side wall of the lever 683 is in contact with the arc-shaped inner wall of the movable groove 685, so that the opening or closing of the oil guide hole 682 can be adjusted by the lever 683; The connecting plate 684 is fixedly sleeved on a side wall of one end of the rod body 673 outside the base 671 , and a side of the connecting plate 684 away from the rod body 673 is fixedly connected to the shift rod 683 .

[0030] The injection assembly 68 also includes: The sealing ring 686 is fixedly sleeved on the side wall of the gear lever 683 and arranged at intervals and respectively located at the bottom and top of the connecting plate 684. The top of the gear lever 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 sleeve-mounting the gear lever 683.

A second spring is fixedly provided on the inner wall of the placement groove, and the second spring is fixedly connected to the side of the collar 687 away from the ball seat 689.

[0031] In specific implementation, when more lubricating oil is needed due to emergencies, 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 amount of the lubricating oil. At the same time, the plug 674 drives the rod body 673, the connecting plate 684 and the shift rod 683 to move upward, so that the shift rod 683 and the oil guide hole 682 are staggered, so that the lubricating oil enters the oil guide hole 682 through the movable groove 685, and is sprayed onto the surface of the strip through the oil guide hole 682, further increasing the discharge amount of the lubricating oil, which is convenient for actual rolling use. In addition, since the strip is transported obliquely through the tensioning mechanism 3 and the rolling mechanism 2, it is convenient for the lubricating oil to flow between the roller and the strip, thereby improving the lubrication effect and the rolling effect. The lubricating oil is evenly coated on the surface of the steel strip by the coating assembly 67, and the spraying assembly 68 sprays the lubricating oil on the surface of the steel strip, so that the amount of the lubricating oil can be adjusted according to the rolling conditions to improve the rolling effect, and the spraying assembly 68 and the coating assembly 67 are linked to facilitate adjustment according to the actual conditions; The ball body 688 rotates in the ball seat 689 to reduce the friction between the gear lever 683 and the oil guide seat 681, thereby improving the smoothness of the movement of the gear lever 683. The second spring elastically supports the ball body 688, so that the side wall of the gear lever 683 fits the oil guide hole 682, thereby improving the sealing effect of the gear lever 683 on the oil guide hole 682. The sealing ring 686 arranged at intervals further improves the sealing effect of the gear lever 683 on the oil guide hole 682. The connection between the second spring and the ball body 688 is supported by the collar 687, so that the second spring can better act on the ball body 688, thereby improving the stability of the elastic support for the ball body 688. Since the steel strip is arranged at an angle, the coating mechanism 6 and the cleaning mechanism 4 are perpendicular to the conveying direction of the steel strip as a whole, which is convenient for the actual coating of lubricating oil and cleaning. Therefore, it is convenient to tilt the oil guide hole 682 downward to spray the lubricating oil, so that the lubricating oil can flow between the rollers and the steel strip.

A fourth spring is sleeved on the inner wall of the mounting groove 631 and located 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 an annular shape. The adjusting rod 632 is fixedly mounted 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 seat 62 and the movable through groove 66 respectively. A support plate 636 is fixedly provided at one end of the adjusting rod 632 located in the movable through groove 66, and the support plate 636 is designed to be arc-shaped so as to fit with the outer wall of the roller body 64.

[0034] In the specific implementation, the first electromagnet 633 and the second electromagnet 634 are energized. Since the first electromagnet 633 and the second electromagnet 634 are close to each other on the same side, the repulsive force generated drives the second electromagnet 634 to move along the inner wall of the installation groove 631, thereby driving the adjustment rod 632 and the stop plate 636 to move vertically to limit the roller body 64, thereby adjusting the height of the roller body 64, so as to adjust the squeezing force of the cotton wiping plate 65 on the strip steel, so as to adjust the amount of lubricating oil according to the actual rolling demand; By providing the pressure sensor 635 and the fourth spring, when the second electromagnet 634 moves downward, the fourth spring is pressed and acts on the pressure sensor 635, so that the force value monitored by the pressure sensor 635 is convenient for grasping the downward pressing position of the second electromagnet 634, so as to grasp the amount of lubricating oil applied; The first slider is moved in the first slide groove 612 to limit the movement of the roller body 64. The first slider is moved along the guide rod 611 to further improve the limiting effect. The third spring is limited to facilitate the third spring to elastically support the roller body 64, so that the cotton wiper plate 65 and the strip steel are not squeezed when no lubricating oil is applied, which is convenient for practical use.

[0035] Example 3: Please refer to Fig.15 , Fig.16 and Fig.17 The difference between this embodiment and the second embodiment is that the cleaning mechanism 4 includes: The connecting seat 42 is fixedly arranged on the side of the first slider away from the roller body 64 and is located on the outside of the frame 1. The outside of the mounting seat 62 is provided with a first through groove connected to 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. A scraper 43 is slidably arranged on the inner side of the connecting seat 42. The scraper 43 is designed in a bent shape so that an inner groove 45 is formed on the side of the scraper 43 away from the rolling mechanism 2. Drainage grooves 5 are provided on both sides of the frame 1 and at the bottom of the scraper 43; The push plate 491 is sleeved on the inner wall of the inner groove 45. The top of the inner groove 45 is provided with a second slide groove 49. A second slider is placed inside the second slide groove 49. The bottom of the second slider is fixedly connected to the top of the push plate 491. The reciprocating screw rod 48 is rotatably arranged on the side wall of the connecting seat 42. The side wall of the reciprocating screw rod 48 is threadedly connected with a threaded tube. The outer wall of the threaded tube is fixedly provided with a mounting plate, and the mounting plate is fixedly connected with the push plate 491. The inner wall of the inner groove 45 is provided with a second through groove for sleeve mounting the mounting plate. The roller 44 is arranged on one side of the scraper 43 close to the roller body 64 , and a rotating rod is fixedly sleeved on the inner wall of the roller 44 , and both ends of the side wall of the rotating rod are rotatably connected to the connecting seat 42 , and the rotating rod is transmission-connected to the reciprocating screw 48 .

[0036] The cleaning mechanism 4 also includes: The top plate 41 is fixedly arranged on the inner side of the connecting seat 42, a third electromagnet 46 is fixedly arranged on the bottom of the top plate 41, a fourth electromagnet 47 is fixedly arranged on the top of the scraper 43, and the side where the fourth electromagnet 47 and the third electromagnet 46 are close to each other is the same pole; The third slide groove 492 is opened on the inner side of the connecting seat 42 . A third slider is placed inside the third slide groove 492 . The third slider is fixedly connected to the scraper 43 .

[0037] In specific implementation, when the height of the roller body 64 is adjusted by adjusting the assembly 63, the first slider drives the connecting seat 42 to move along the first through groove, so that the connecting seat 42 and the roller body 64 move synchronously, which is convenient for preliminary adjustment of the position of the scraper 43 to better adapt to strips of different thicknesses, and the repulsive force generated by the third electromagnet 46 and the fourth electromagnet 47 after power-on drives the scraper 43 to move downward, so that the bottom of the scraper 43 is pressed against the top of the strip, so as to facilitate the scraping of the strip during the conveying process, thereby removing impurities remaining on the surface of the strip, avoiding the subsequent impact on the contact between the lubricating oil and the strip, and improving the lubrication and rolling effects, and by setting the roller 44, The roller 44 is made to press against the surface of the steel strip while the connecting seat 42 moves downward, thereby driving the roller 44 to rotate during the conveying of the steel strip, thereby driving the rotating rod to rotate. Since the rotating rod is connected to the reciprocating screw 48, the mounting plate and the push plate 491 are driven to move along the second slide groove 49 and the second through groove during the rotation of the reciprocating screw 48, so as to push the impurities accumulated in the groove 45 in the scraper 43. Since the connecting seat 42 is located on the outside of the frame 1, the accumulated impurities are pushed to the outside of the frame 1 during the reciprocating movement of the push rod, and discharged along the drain chute 5, so as to facilitate the cleaning of the impurities pushed in the groove 45 in the scraper 43, so as to facilitate the long-term cleaning of the steel strip.

[0038] The first electromagnet 633 and other electronic devices of the present invention are connected to an external power source through wires, which is convenient for actual control and use. The lubricating oil external oil circuit of the present invention is used to transport lubricating oil to the roller body 64. The above are all existing technologies and will not be elaborated here.

[0039] The embodiment of the present invention further provides a method for using a strip steel coil mill with a front tension adjustment mechanism. The strip steel coil mill with a front tension adjustment mechanism is used, and the method comprises the following steps: S1: Before the steel strip is conveyed to the rolling mechanism 2, the top and bottom of the steel strip are coated with lubricating oil by the coating mechanism 6, so as to roll the steel strip subsequently. During the coating process, the height of the roller body 64 and the cotton wiping plate 65 is adjusted by the adjustment component 63 and the limit component 61, so as to coat the steel strips with different thicknesses with lubricating oil, and the tightness between the roller body 64 and the steel strip is adjusted by the adjustment mechanism, so that the steel strip is squeezed against the cotton wiping plate 65 by the reaction force, so as to adjust the amount of lubricating oil discharged through the cotton wiping plate 65 by the coating component 67, so as to adjust the amount of lubricating oil discharged according to the actual rolling conditions and improve the actual rolling effect. When the cotton wiping plate 65 moves upward to the maximum extent and cannot move, the lubricating oil is sprayed outward by the spray mechanism, and the steel strip is conveyed at an angle, so as to facilitate the lubricating oil to flow between the roller and the steel strip, so as to meet the actual rolling use. S2: When applying lubricating oil to the surface of the steel strip, the cleaning mechanism 4 and the coating mechanism 6 are linked to clean the portion of the steel strip to be coated with lubricating oil, remove debris and impurities on the surface of the steel strip, and facilitate the subsequent contact between the lubricating oil and the surface of the steel strip, thereby improving the lubrication effect and facilitating actual rolling use.
