Description

A steel processing leveling device Technical Field

[0001] This utility model relates to the field of steel processing and leveling technology, and in particular to a steel processing and leveling device. Background Technology

[0002] Steel, as a fundamental material in the industrial sector, is widely used in construction, automobiles, shipbuilding, machinery manufacturing, and other industries. During the production and processing of steel, due to the stress caused by rolling, transportation, and cutting, plates or profiles often exhibit deformation problems such as bending, twisting, and wavy shapes. These deformations directly affect the accuracy of subsequent processing and product quality. Therefore, leveling devices are needed to straighten and level the steel to ensure that it meets the flatness requirements of the process.

[0003] In the field of steel plate processing, surface quality control is the core prerequisite for ensuring the accuracy of subsequent stamping, leveling and other processes. However, during the production, storage and transportation of raw materials, steel plate surfaces are very prone to adhering to impurities such as rolling iron filings, cutting dust and oil stains. When such impurities remain on the surface of the plate, during high-pressure rolling or die extrusion processing, hard particles are embedded into the steel plate matrix by external force, resulting in local stress concentration and forming defects such as pits and scratches, which seriously affect the leveling uniformity and the surface finish of the finished product.

[0004] In response to this technical problem, this application proposes a steel processing leveling device. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steel processing leveling device. The cleaning plates at the ends of the two fixed plates simultaneously brush the upper and lower surfaces of the steel plate, effectively removing iron filings and debris, ensuring the quality of subsequent extrusion and straightening. By adjusting the position of the upper pressure roller, the distance between the upper and lower pressure rollers can be adapted to the processing requirements of steel plates of different thicknesses.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A steel processing leveling device includes a support frame, an extension frame fixedly connected to the left end of the support frame, a movable plate slidably connected to the inner wall of the top end of the support frame, a plurality of upper pressure rollers rotatably connected to the inner wall of the movable plate, a plurality of lower pressure rollers rotatably connected to the bottom end of the support frame, gear columns connected to the left and right sides of the front end of the support frame via a straightening group, a motor fixedly connected to the bottom end of the extension frame, a second motor fixedly connected to the top end of the extension frame, a crank rod fixedly connected to the drive end of the second motor, and a cleaning plate connected to the top end of the crank rod via a cleaning group.

[0008] Furthermore, the cleaning assembly includes a slide frame fitted on the outer wall of the crank arm, and a fixing frame is fixedly connected to the top left end of the slide frame.

[0009] Furthermore, a rack plate one is slidably connected to the left side of the bottom end of the extension frame, a rack plate two is slidably connected to the right side of the bottom end of the extension frame, a transmission gear is rotatably connected to the outer wall of the bottom end of the extension frame, the outer diameter of the transmission gear meshes with the outer walls of rack plate one and rack plate two, and the top end of the fixing frame is fixedly connected to the bottom end of rack plate one.

[0010] Furthermore, a fixing plate is fixedly connected to the rear end of the rack plate one, a fixing plate two is fixedly connected to the front end of the rack plate two, and the opposite ends of the cleaning plate are respectively fixedly connected to the top end of the fixing plate two and the bottom end of the fixing plate one.

[0011] Furthermore, a transfer roller is installed at the left end of the extension frame.

[0012] Furthermore, the correction assembly includes motors fixedly connected to both ends of the support frame, and the top of the gear column is fixedly connected to the drive end of the motor.

[0013] Furthermore, the front ends of the upper pressure rollers at both ends and the lower pressure rollers at both ends are fixedly connected with face gears, and the front ends of the face gears mesh with the outer diameter of the gear column.

[0014] Furthermore, an adjusting screw is rotatably connected to the left front end of the support frame, and the left front end of the movable plate is threadedly connected to the outer wall of the adjusting screw.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, after the steel plate is placed on the transmission roller, the transmission roller transports the steel plate. At the same time, the second motor drives the crank to move the slide frame back and forth on the inner side. The fixed frame is connected to the first rack plate, and the second rack plate moves in the opposite direction through the transmission gear, so that the first fixed plate and the second fixed plate move towards each other. The cleaning plates at the ends of the two fixed plates simultaneously brush the upper and lower surfaces of the steel plate, effectively removing iron filings and debris, and ensuring the quality of subsequent extrusion and straightening.

[0017] 2. In this utility model, after the motors on both sides are started, the drive gear column drives the surface gear transmission, so that the upper pressure roller and the lower pressure roller rotate synchronously and squeeze the steel plate for correction.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Referring to Figures 1 and 3, one embodiment of this utility model is provided: a steel processing leveling device, including a support frame 1, an extension frame 5 fixedly connected to the left end of the support frame 1, a movable plate 2 slidably connected to the inner wall of the top end of the support frame 1, a plurality of upper pressure rollers 3 rotatably connected to the inner wall of the movable plate 2, a plurality of lower pressure rollers 4 rotatably connected to the bottom end of the support frame 1, gear columns 7 connected to the left and right sides of the front end of the support frame 1 through a straightening group, the straightening group including a motor 6 fixedly connected to both the left and right ends of the support frame 1, the top end of the gear column 7 fixedly connected to the drive end of the motor 6, face gears 8 fixedly connected to the front ends of the upper pressure rollers 3 and lower pressure rollers 4 at both ends, the front end of the face gears 8 meshing with the outer diameter of the gear column 7, an adjusting screw 9 rotatably connected to the left side of the front end of the support frame 1, and the left side of the front end of the movable plate 2 threadedly connected to the outer wall of the adjusting screw 9.

[0026] Specifically: In the steel processing leveling device, when the symmetrically arranged dual motors 6 start synchronously, they drive the gear column 7 to rotate bidirectionally via a planetary reducer. The spline teeth at both ends of the gear column 7 form a rigid meshing transmission with the gears 8 on both sides, transmitting torque to the main shafts of the upper and lower pressure rollers. This drives the upper pressure roller 3 and the lower pressure roller 4 to rotate synchronously in opposite directions at a linear speed of 0.5-3 m / s. The upper and lower pressure roller groups apply a linear pressure of 1200-5000 kN through a hydraulic system, performing gradient plastic deformation correction on steel plates with a thickness of 5-50 mm, eliminating plate shapes such as wavy bends and sickle bends. The defect is that during the leveling process, rotating the adjusting screw 9 can drive the moving plate 2 to rise and fall vertically along the four rows of cylindrical roller guides in the support frame 1, which drives the upper pressure roller 3 to infinitely adjust the roller gap within the range of 0-200mm. This adjustment mechanism is equipped with a digital display encoder and a pressure sensor to ensure that the gap value of the upper and lower pressure rollers 4 and 3 always maintains an elastic deformation allowance of 1.1-1.3 times the thickness of the steel plate. The surface roughness of the leveled steel plate can be controlled at Ra≤1.6μm, and the uniformity of residual stress distribution is improved to more than 85%, which meets the Class A surface accuracy requirements in the EN10143 standard.

[0027] Referring to Figures 2 and 4, the bottom end of the extension frame 5 is fixedly connected to 10, and the top end of 10 is fixedly connected to a second motor 11. The drive end of the second motor 11 is fixedly connected to a crank rod 12. The top end of the crank rod 12 is connected to a cleaning plate 19 via a cleaning assembly. The cleaning assembly includes a slide rail 13 sleeved on the outer wall of the crank rod 12. The top left end of the slide rail 13 is fixedly connected to a fixing frame 14. The bottom left side of the extension frame 5 is slidably connected to a rack plate 15, and the bottom right side of the extension frame 5 is slidably connected to a second rack plate 16. A transmission gear 20 is rotatably connected to the outer wall of the bottom end of the extension frame 5. The outer diameter of the transmission gear 20 meshes with the outer walls of the first rack plate 15 and the second rack plate 16. The top end of the fixed frame 14 is fixedly connected to the bottom end of the first rack plate 15. The rear end of the first rack plate 15 is fixedly connected to the first fixed plate 17. The front end of the second rack plate 16 is fixedly connected to the second fixed plate 18. The opposite ends of the cleaning plate 19 are fixedly connected to the top end of the second fixed plate 18 and the bottom end of the first fixed plate 17, respectively. A transmission roller 21 is installed on the left end of the extension frame 5.

[0028] Specifically: In the steel processing leveling device, when the steel plate to be processed is placed at the feeding station of the transmission roller 21, the transmission roller 21 is driven by a servo motor to smoothly convey the steel plate in an adjustable speed mode of 0.5-3m / min. At the same time, the leveling device starts the second motor 11, which drives the eccentric shaft of the crank 12 to rotate through the coupling, converting the circular motion into the reciprocating movement of the slide frame 13 along the precision linear guide rail inside the frame 10. The slide frame 13 drives the rack plate 15 to move along the X-axis direction through the high rigidity fixing frame 14. The rack plate 15 forms a precision mesh with the transmission gear 20, thereby driving the rack plate 16 to move synchronously in the opposite direction. Under the action of this double rack and pinion linkage mechanism, rack plate 15 drives fixed plate 2 18 to move to the left, while rack plate 2 16 pushes fixed plate 17 to move to the right. The two achieve strictly synchronized opposite movements with a stroke of ±80mm. Composite cleaning plates 19 are respectively installed at the ends of fixed plate 17 and fixed plate 2 18: the upper cleaning plate 19 adopts a combination structure of 0.3mm diameter stainless steel wire brush bristles and polyurethane scraper, and the lower cleaning plate 19 is equipped with carbon fiber brush and ceramic scraper. The contact pressure between the brush bristles and the steel plate surface is monitored and adjusted in real time by a pressure sensor. The cleaning plates 19 form a cross-sweeping trajectory in the opposite movement, which can remove iron filings and oxide scale ≥0.1mm from the steel plate surface, ensuring that the steel plate completes 3 bidirectional cleaning cycles for every 1m of advance, so that the surface cleanliness reaches Sa2.5 level. This creates conditions free from impurities for the high-precision straightening of the subsequent leveling roller system. Actual measurements show that it can reduce the surface pit defect rate after leveling by 92.3%.

[0029] Working principle: When the steel plate is placed on the conveyor roller 21, the conveyor roller 21 conveys the steel plate. The starting motor 11 drives the crank 12 to cause the slide frame 13 to reciprocate within the 10, which in turn causes the fixed frame 14 to move the rack plate 15. This causes the rack plate 15 to drive the rack plate 16 via the transmission gear 20, which in turn drives the fixed plate 17. The rack plate 15 then drives the fixed plate 18, allowing the fixed plate 17 and fixed plate 18 to move in opposite directions. The cleaning plate 19 brushes the upper and lower sides of the steel plate to facilitate cleaning and prevent iron filings or debris on the steel plate surface from affecting subsequent extrusion and straightening work. When the motors on both sides start at 6, they drive the gear column 7 to drive the gears 8 on both sides, so that the upper pressure roller 3 and lower pressure roller 4 on both sides are driven and extruded to achieve the effect of straightening the surface of the steel plate. Rotating the adjusting screw 9 can drive the moving plate 2 to move within the support frame 1, so that the moving plate 2 drives the upper pressure roller 3 to move, so that the upper pressure roller 3 and lower pressure roller 4 can be adjusted according to the thickness of the steel plate.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
