Description

Technical Field

[0001] This invention relates to the field of steel rolling equipment technology, specifically to a roller groove adjustment guide device for a steel rolling mill. Background Technology

[0002] In modern industrial systems, steel rolling technology, as the core hub of steel material forming, profoundly impacts the development quality of pillar industries such as construction, machinery manufacturing, automotive, and energy equipment through its processing precision and production efficiency. As the core equipment in the metal rolling process, the rolling mill achieves material shaping through the interaction between the roll grooves and the metal billet. The roll groove adjustment guide device, as the "precision control center" of the rolling mill, directly determines the quality stability, production continuity, and economic benefits of steel products. In this context, adjusting the position, angle, and depth of the rolling mill roll grooves has become a core technical point for ensuring that the dimensional accuracy, surface finish, and internal structure of steel meet stringent process standards.

[0003] However, the existing rolling mill roll grooves have the following shortcomings during the adjustment process:

[0004] (1) In modern steel rolling production process, the discrete adjustment architecture of the traditional roll groove adjustment guide device has a fundamental defect. Each roll adjustment unit lacks a collaborative control mechanism, making it difficult to achieve one-time accurate reset and alignment of multiple roll grooves.

[0005] (2) The lack of function to independently adjust the guide of a single roll groove makes it impossible to meet the processing requirements of special-shaped reinforcing ribs, which restricts the development and production of irregular steel products and makes it difficult to adapt to diversified market demands.

[0006] (3) Because the depth of the roll groove cannot be controlled, the height of the reinforcing ribs cannot be controlled during steel rolling, and diversified products cannot be rolled out.

[0007] (4) The heat generated by work hardening during steel rolling will cause the temperature of the steel to rise significantly. Uneven temperature distribution will not only cause shape defects such as warping and wavy shape of the steel plate, but also affect the uniformity of its internal metallographic structure, thereby reducing the strength, toughness and other mechanical properties of the steel plate.

[0008] To address this issue, we propose a roller groove adjustment guide device for steel rolling mills. Summary of the Invention

[0020] This invention provides a roll groove adjustment guide device for a steel rolling mill. Compared with the prior art, it has the following advantages:

[0021] (1) By setting up the roll groove reset and alignment mechanism, the roll groove of the roll is accurately reset and aligned in one go, so that the two ends of the rolling bar are aligned and the roll groove is parallel to each other, thereby improving the stability of the reinforcing rib formation and the steel forming quality during rolling.

[0022] (2) By independently adjusting the setting of the guide component, the guide of a single roll groove can be independently adjusted, thereby meeting the processing requirements of special-shaped reinforcing ribs. When a certain rolling bar is moved and adjusted, the degree of side bending of the reinforcing rib can be adjusted, realizing the development and production of special-shaped steel products and adapting to diversified market demands.

[0023] (3) By setting the rolling height adjustment component, it is linked with the roll groove reset and alignment mechanism.

[0036] 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.

[0037] The present invention provides three technical solutions, specifically including the following embodiments: Example 1

[0038] Please see Figures 1-3 A roller groove adjustment guide device for a steel rolling mill includes a support frame 1, which provides support for the entire adjustment guide device. The support frame 1 is welded from high-strength alloy steel. Its unique truss structure design can not only withstand huge vertical pressure, but also effectively resist horizontal impact force, providing a stable and reliable support for the entire device. Two crossbars 2 are fixed on the top of the support frame 1, and two brackets 3 are fixed on the top of the support frame 1. The brackets 3 provide support for the setting of the cylinder 47. The brackets 3 are made of thickened steel plate and stamped, providing a solid support foundation for the installation and stable operation of the cylinder 47. A roller groove reset and alignment mechanism 4 is set above the support frame 1.

[0039] The roller groove resetting and alignment mechanism 4 includes a horizontal plate 41 fixed between the opposite sides of two horizontal frames 2. The horizontal plate 41 is made of high-strength alloy steel and is precision machined to ensure that its surface flatness error is controlled within ±0.05mm. A turntable 42 is rotatably mounted on the top of the horizontal plate 41. The turntable 42 adopts a high-precision slewing bearing structure and has double rows of balls inside, enabling flexible and stable rotation of 360 degrees. A rotating plate 43 is fixed on the rotating shaft of the turntable 42. The rotating plate 43 adopts a hollow reinforcing rib structure design, which reduces weight while significantly improving its torsional strength. A slide rail 44 is fixed on the top of each of the two horizontal frames 2. The slide rail 44 is a linear ball bearing slide rail, and the evenly distributed balls inside can... Sliding friction is converted into rolling friction, which greatly reduces frictional resistance and improves the smoothness and precision of the motion. Two movable plates 45 are installed above the two crossbeams 2, and two slide blocks 46 are fixed to the bottom of each movable plate 45. The four slide blocks 46 slide on the slide rail 44, which has grooves. The slide rail 44 passes through the grooves and slides within them. This design allows the movable plates 45 to achieve high-precision linear reciprocating motion on the slide rail 44, with a positioning accuracy of ±0.1mm. Cylinders 47 are fixed to the top of both brackets 3. These cylinders are high-precision double-acting cylinders, controlled by an external programmable logic controller (PLC) switch, and electrically connected to a stable external power supply. The precise program settings enable accurate control of the extension and retraction stroke of cylinder 47, with a control accuracy of ±0.02mm. The output ends of both cylinders 47 are fixed to the moving plate 45. When cylinder 47 is working, it can stably and powerfully push the moving plate 45 to slide on the slide rail 44. Rotary arms 48 are rotatably connected to both sides of the top of the rotating plate 43. One end of each rotating arm 48 is rotatably connected to the top of the moving plate 45. The rotating arms 48 are rotatably connected to the top of the rotating plate 43 and the moving plate 45 through high-precision pins. This rotatable connection method, combined with the precision bearing design, can achieve flexible angle changes while ensuring connection strength. Multiple upright plates 49 are fixed to the top of the moving plate 45, and independent adjustment guide components 5 are set on the upright plates 49.

[0040] Both sides of the support frame 1 are fixed with U-shaped frames 7. The U-shaped frames 7 are made of high-strength cast steel. Their unique U-shaped structure design can provide stable and reliable support for the rolling rod 8. The rolling rod 8 is slidably connected between the inner surfaces of the two U-shaped frames 7. The rolling rod 8 is made of high-hardness alloy steel and undergoes a special heat treatment process to achieve a surface hardness of HRC55-60 while maintaining good internal toughness. The rolling rod 8 can rotate in the U-shaped frames 7. Rolls 9 are fixed on the rolling rod 8. The rolls 9 are manufactured using a centrifugal casting process and their surfaces undergo a special wear-resistant treatment to achieve a hardness of HRC60-65. The rolling rod 8 is linked with an external high-performance drive device. Through a high-precision coupling and transmission belt, the stability and accuracy of power transmission are ensured. The two adjacent rolls 9 form a groove. The two ends of the rolling rod 8 contact and squeeze one side of the reset ball 52.

[0041] By setting up the roll groove reset and alignment mechanism 4, the roll groove of the roll 9 is accurately reset and aligned in one go, so that the two ends of the rolling bar 8 are aligned and the roll groove of the roll 9 is parallel. This improves the stability of the reinforcing rib formation and the quality of steel forming during rolling. Actual tests show that after using this device, the dimensional accuracy error of the steel is reduced from ±0.3mm to within ±0.1mm, and the forming qualification rate of the reinforcing rib is increased from 85% to over 98%. Example 2

[0042] Based on Example 1, see Figures 4-5 As shown, the independent adjustment guide assembly 5 includes a slide rod 51 slidably connected to one side of the upright plate 49. The slide rod 51 is made of high-strength alloy steel and is precision ground to ensure that its surface roughness Ra≤0.8μm, thereby reducing the frictional resistance between it and the upright plate 49. One end of the slide rod 51 passes through the upright plate 49 and extends to the outside of the upright plate 49. A reset ball 52 is fixed to one end of the slide rod 51. The reset ball 52 is made of hard metal material, such as hard alloy, with a hardness of up to HRA90-92. It does not have deformation or ductility and can ensure that it maintains a stable shape and size during long-term use, ensuring the contact accuracy with the rolling rod 8. A handle 53 is fixed to the other end of the slide rod 51.

[0043] A circular plate 54 is fixed on the slide rod 51, and a spring 55 is fitted on the slide rod 51. The spring 55 is made of high-elasticity alloy spring steel, and its elastic coefficient has been accurately calculated and tested to provide stable and appropriate elastic force for the reset of the slide rod 51. One end of the spring 55 is fixed to one side of the circular plate 54, and the other end of the spring 55 is fixed to one side of the upright plate 49. Multiple insertion holes 56 are spaced apart on one side of the slide rod 51, and the distance between two adjacent insertion holes 56 is 1cm. By observing the movement of several insertion holes 56, the operator can intuitively and accurately judge the displacement distance of the rolling rod 8. An L-shaped plate 57 is provided on one side of the upright plate 49.

[0044] A horizontal tube 58 is fixed to one side of the L-shaped plate 57, and a plug rod 59 is slidably connected to one side of the L-shaped plate 57. One end of the plug rod 59 passes through the L-shaped plate 57 and the horizontal tube 58 and extends into the interior of the insertion hole 56. The size of the plug rod 59 is adapted to the size of the insertion hole 56. The size of the plug rod 59 and the insertion hole 56 are precisely designed and processed to achieve a tight fit, ensuring that the plug rod 59 can reliably lock the slide rod 51. The outer surface of the plug rod 59 is slidably connected to the inner surface of the horizontal tube 58. A pull ring 510 is fixed to the other end of the plug rod 59. The pull ring 510 facilitates the operator to perform insertion and removal operations.

[0045] By independently adjusting the guide component 5, the guide of a single roll 9 groove can be independently adjusted, thereby meeting the processing requirements of special-shaped reinforcing ribs. When a certain rolling bar 8 is moved and adjusted, the degree of lateral bending of the reinforcing rib can be adjusted, realizing the development and production of irregular steel products and adapting to diversified market demands. Practical application has verified that after adopting this independently adjusting guide component 5, more than 20 different shapes of irregular steel products can be produced, increasing the product variety by more than 3 times compared to before. Example 3

[0046] Based on Example 2, see Figures 6-10 As shown, a rolling height adjustment assembly 6 is installed above the rotating plate 43. The rolling height adjustment assembly 6 includes two L-shaped frames 61 fixed to the top of the support frame 1. The L-shaped frames 61 are welded from high-strength alloy steel. Their structural design fully considers mechanical performance and can withstand huge vertical pressure and horizontal tension. Between the opposite sides of the two L-shaped frames 61, a disc 62 is fixed. The disc 62 is made of high-strength cast steel and is precision machined to ensure that its surface flatness error is controlled within ±0.03mm. Five square tubes 63 are fixed on the disc 62. Telescopic arms 64 are slidably connected inside the five square tubes 63. The telescopic arms 64 are adapted to the size of the square tubes 63. The two ends of the square tubes 63 are open-type designs to facilitate the installation and maintenance of the telescopic arms 64.

[0047] Each of the five telescopic arms 64 has a limit post 65 fixed to its top. A drive disk 66 is rotatably connected to the bottom wall of the disc 62 via a rotating shaft. Five arc grooves 67 are opened through the top of the drive disk 66. The top of the limit post 65 passes through the arc groove 67 and extends to the outside of the arc groove 67. The size of the limit post 65 is adapted to the arc groove 67. The outer surface of the limit post 65 is slidably connected to the inner surface of the arc groove 67. The rotating shaft of the turntable 42 is fixed to the rotating shaft of the drive disk 66 via a coupling. A block 68 is fixed to one end of the telescopic arm 64.

[0048] A protruding rod 69 is fixed to the top of block 68, and a U-shaped plate 610 is fixed to the top of the protruding rod 69. A rotating roller 611 is rotatably connected between opposite sides of the U-shaped plate 610. The rotating roller 611 is made of high-hardness alloy steel, and its surface has undergone special wear-resistant treatment, achieving a hardness of HRC60-65. A vertical tube 612 is fixed to the top of each of the two L-shaped frames 61, and a top rod 613 is slidably connected to the top of each of the two vertical tubes 612. The bottom ends of the two top rods 613 extend into the interior of the vertical tubes 612. A support plate 614 is fixed between the top ends of the two top rods 613. The support plate 614 is made of high-strength alloy steel plate, and its surface has undergone special anti-rust treatment. A conical seat 615 is fixed at the bottom of the plate 614. Multiple ventilation holes 616 are provided through the conical seat 615. The ventilation holes 616 allow the air blown by the fan blade 105 to act on the bottom of the steel through the plate 614. The outer surfaces of the five rollers 611 roll in contact with the bottom of the conical seat 615. The conical seat 615 is manufactured using high-precision CNC machining technology, and its taper error is controlled within ±0.01°. The unique design of the conical seat 615 allows the rollers 611 to drive the conical seat 615 and the plate 614 to perform precise upward or downward movements when they roll.

[0049] By setting the rolling height adjustment component 6 and linking it with the roll groove reset and alignment mechanism 4, the rotation of the turntable 42 synchronously drives the drive plate 66 to rotate synchronously, thereby causing the five rotating rollers 611 to drive the lifting and lowering of the support plate 614, adjusting the distance between the steel and the roll groove of the rolling roll 9, thus realizing the control of the height of the reinforcing rib during steel rolling, and thus realizing the rolling of diversified products. In this way, the height of the reinforcing rib can be flexibly adjusted according to different production needs, achieving the goal of rolling diversified products. According to actual tests, after using this rolling height adjustment component 6, the height adjustment range of the reinforcing rib can reach 5-50mm, and the height control accuracy can reach ±0.2mm, which can meet the diversified needs of different customers for steel products.

[0050] The rolling height adjustment assembly 6 is equipped with a linkage cooling assembly 10. The linkage cooling assembly 10 includes an L-shaped seat 101 fixed to the bottom of the square tube 63, a rack 102 fixed to one side of the block 68, a vertical rod 103 rotatably connected to the top of the L-shaped seat 101, a gear 104 fixed on the vertical rod 103, the gear 104 meshing with the rack 102, and a fan blade 105 fixed to the top of the vertical rod 103. The fan blade 105 can be driven by the vertical rod 103 to rotate in both directions. After the fan blade 105 rotates, it can generate an upward wind. The wind passes through the ventilation hole 616 and acts on the bottom of the steel to cool it down.

[0051] By setting up the linkage cooling component 10, which is linked with the rolling height adjustment component 6, when the telescopic arm 64 moves in extension and retraction, it can synchronously drive the rack 102 to move, and drive the gear 104 and fan blade 105 to rotate, thereby blowing air upward to quickly cool the bottom of the rolled steel, thereby preventing warping, wavy and other shape defects of the steel, and improving the strength, toughness and other mechanical properties of the steel plate.

[0052] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0053] During operation, two cylinders 47 are activated to retract, which in turn moves one of the moving plates 45. The moving plate 45 then rotates the rotating arm 48, which in turn rotates the rotating plate 43. The rotating plate 43 then rotates the turntable 42, which in turn moves the other moving plate 45. The two moving plates 45 move in opposite directions, which in turn moves the vertical plate 49 and the reset ball 52 in opposite directions. The reset ball 52 then contacts and presses against both ends of the rolling bar 8, while simultaneously causing the rolling bar 8 and the roll 9 to reset and align. Align the rolls 9 on the three rolling bars 8 to make them parallel. When it is necessary to roll a reinforcing rib of a special shape, control one of the independent adjustment guide components 5 to work. Specifically, pull the pull ring 510 to make the insert rod 59 slide out of the insertion hole 56, which in turn pushes the handle 53. The handle 53 drives the slide rod 51 and the reset ball 52 to move, and the reset ball 52 drives the rolling bars 8 and the rolls 9 to move. Use the insertion hole 56 to record the distance the roll 9 moves. The distance between two adjacent insertion holes 56 is 1 cm. After the adjustment is completed, push the pull ring 510 again. 10. Insert the insertion rod 59 into the insertion hole 56 to lock the slide rod 51. During the rotation of the turntable 42, the turntable 42 drives the drive plate 66 to rotate. The drive plate 66 drives the limiting post 65 to slide in the arc groove 67. In turn, the limiting post 65 drives the five telescopic arms 64 to extend and retract radially in the square tube 63. This causes the rotating roller 611 to roll at the bottom of the conical seat 615. When the five rotating rollers 611 retract, they can drive the conical seat 615 and the support plate 614 to move upward. When the five rotating rollers 611 extend, they can drive... The conical seat 615 and the support plate 614 move down, placing the steel to be rolled on the support plate 614. This allows control over the raising and lowering of the steel, and consequently, the height of the reinforcing ribs during rolling. When the telescopic arm 64 extends or retracts, it simultaneously drives the rack 102 to move. The rack 102 drives the gear 104 to rotate, which in turn drives the vertical rod 103 and the fan blade 105 to rotate. The rotating fan blade 105 generates upward-flowing cold air, which is blown into the ventilation hole 616 and onto the bottom of the steel, rapidly cooling the rolled steel.

[0054] The embodiments of the invention have been described in detail above, but the content described is only a preferred embodiment of the invention and should not be considered as limiting the scope of the invention. All equivalent changes and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
