Description

Technical Field

[0001] The invention belongs to the technical field of stainless steel composite plate rolling, and in particular relates to a buckle head control device and process for rolling stainless steel composite plates. Background Art

[0002] In the rolling production process of stainless steel composite plates, due to the uneven temperature distribution and uneven deformation in the thickness direction of the plate, studies have shown that different roller diameters, rotation speeds, surface conditions, and unequal upper and lower surface temperatures of the rolled piece can all lead to asymmetric rolling. Under asymmetric rolling conditions, when the workpiece bites, the rolling line height is too high or too low, causing uneven force on the front end, and the head of the workpiece will bend up and down. The upward bending is called "warp head" and the downward bending is called "buckle head"; when the warp head is too large, the workpiece is easy to hit the roller body, and in severe cases, a "roller entanglement" accident may occur; when the buckle head is too large, the workpiece hits the conveyor roller, and in severe cases, the equipment may even be stuck; according to the above situation, the temperature of the plate should be maintained as much as possible during the plate transportation process to avoid large changes in temperature difference, and the surface of the plate should be cleaned in advance to prevent impurities such as oxide scale from affecting subsequent processes. By setting a guide roller positioning frame with an arc-shaped front end, the plate that has already produced warp and buckle heads can be prevented from hitting the conveyor roller. During the straightening process, the roller speed of the upper and lower straightening rollers is controlled, and the upper and lower straightening rollers are guaranteed to contact the plate surface at the same time to avoid the warp head phenomenon caused by asymmetric rolling. Then, a detection mechanism is set to detect whether the flatness of the plate meets the standard to complete the straightening work.

[0003] After searching, the prior art authorization publication number is CN 118106353 A, which is a stainless steel production rolling mill, including a hollow plate, the four corners of the bottom of the hollow plate are fixedly connected to support columns, the right side of the outer wall of the hollow plate is fixedly connected to a first support plate, and also includes an adjustment mechanism, the ends of the two lifting blocks close to each other are sleeved and rotatably connected to a lifting rod, when working, the first motor rotates, the first motor drives the first rotating rod to rotate, the first rotating rod drives the first belt and the second rotating rod to rotate, and the second rotating rod drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear and the threaded rod to rotate, the threaded rod drives the lifting block to move on the inner wall of the square hole, the lifting block drives the lifting rod and the steel plate to lift, and the lifting rod is driven by the forward and reverse rotation of the first motor to adjust up and down, which can be adjusted according to the thickness of the steel plate; when the rolling mill is working, the lifting rod is driven by the forward and reverse rotation of the first motor to adjust up and down. When the workpiece is bitten, it cannot be guaranteed that the upper and lower rollers are subjected to force on the workpiece at the same time. The rolling line height is too high or too low, which makes the front end unevenly stressed, resulting in asymmetric rolling and causing the workpiece to have a buckled head.

[0004] After searching, a steel plate straightening machine with the prior art authorization publication number CN 118635307 A is found, which includes a base, and the outer walls on both sides of the base are provided with slide grooves, the slide grooves are connected with the inner cavity of the base, the inner cavity of the base is provided with straightening rollers, and also includes an adjustment mechanism and a displacement mechanism. By setting an adjustment mechanism and a displacement mechanism, the rotating disk is rotated to drive the two movable seats to slide in the movable groove. The movable seat moves and drives the adjustment seat to slide through the connecting rod, and the distance between the upper and lower adjustment seats is adjusted, so as to adjust the distance of the straightening rollers. Then, the fixed frame is pushed downward, and the fixed block is moved and inserted into the fixed groove to fix the rotating disk. During this process, the pushing block moves and drives the displacement seat to slide in the displacement groove. The movement of the displacement seat drives the second straightening roller to move a distance, so as to adjust the upper and lower distances of the straightening rollers. When the positions of the straightening rollers on both sides are fixed, the position of the straightening roller in the middle part is automatically moved. The device adopts multiple groups of straightening rollers for straightening work, and drives the adjustment seat to slide through the connecting rod to adjust the distance between the upper and lower adjustment seats. During the straightening work, the rotation speed of the upper and lower straightening rollers cannot be guaranteed to be consistent, resulting in asymmetric rolling and buckling of the rolled piece. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a buckle control device and process for rolling stainless steel composite plates. The centering conveying mechanism centers the plates while conveying the plates. The upper and lower insulation cabins and insulation covers ensure that the plates maintain temperature during the re-conveying process to avoid buckles caused by large temperature differences. The cleaning guide mechanism effectively cleans the oxide scale and other impurities on the surface of the plates. By setting the front ends of the two sets of guide roller positioning frames to an arc shape, the stainless steel composite plates are guaranteed to be clamped by the guide rollers in the center, whether they are warped or buckled, to avoid the mechanism jamming due to the warping and buckling of the plates. The straightening mechanism first uses a centering mechanism composed of two sets of racks and gears to ensure that the upper and lower straightening rollers are in contact with the surface of the plates at the same time, to avoid buckles caused by uneven force on the front ends when the plates are bitten into, and the upper and lower straightening rollers are rotated at the same speed through the cooperation between the gears to avoid buckles caused by inconsistent speeds of the upper and lower straightening rollers. The cleaning wiping roller cleans the impurities adhering to the straightening roller to avoid poor straightening effect caused by impurities adhering to the straightening roller. Finally, the straightening effect is detected by the detection mechanism to see if it is qualified.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A buckle head control device and process for rolling stainless steel composite plates, the specific method and steps of using the device are as follows:

[0008] 1) Insulated conveying: There are multiple groups of conveying rollers I arranged inside the insulation cabin, and an insulation cover is provided on the upper part of the insulation cabin. The insulation cabin and the insulation cover keep the temperature of the stainless steel composite plate stable during the conveying process. The stainless steel composite plate is conveyed in the insulation cabin and the insulation cover through the conveying rollers I for insulation conveying;

[0009] 2) Centering and positioning: Motor I controls the rotation of connecting rod II, connecting rod II drives connecting rods I at both ends to rotate, and connecting rod I drives the sliding guide plate to slide along the direction of support rod I, so that the vertical guide rollers between the two sets of sliding guide plates are centered and clamped, so that the vertical guide rollers are horizontally centered and clamped on both sides of the stainless steel composite plate during the conveying process;

[0010] 3) Scraping and blowing: Motor II drives transmission shaft I to rotate, and drives bidirectional screw I and bidirectional screw II to rotate, so that the two sets of lifting plates and buffer plate I set on bidirectional screw I and bidirectional screw II are aligned and clamped, and buffer plate I drives scraper positioning plate to descend through spring I, and scraper positioning plate drives inclined scraper to descend to scrape the surface of plate, and the scraped oxide scale is blown off through the air blowing pipe;

[0011] 4) Longitudinal guide: Motor II drives transmission shaft I to rotate, and drives bidirectional screw I and bidirectional screw II to rotate, so that the two sets of lifting plates set on bidirectional screw I and bidirectional screw II are centered and clamped, and the lifting plates drive the guide roller positioning frame and guide roller to descend. The front ends of the upper and lower guide roller positioning frames are arc-shaped, and the guide rollers are set in the guide roller positioning frames to ensure that the stainless steel composite plate is longitudinally centered and clamped by the guide rollers regardless of whether it is warped or buckled, so as to avoid the mechanism jamming due to the warping and buckling of the plate;

[0012] 5) Roller speed synchronization: Motor III drives seven groups of gears from gear I to gear VII to rotate through the meshing between gears, ensuring that the speeds of gear II and gear VI are consistent, thereby ensuring that the speeds of the two groups of straightening rollers are consistent, avoiding the occurrence of buckle head phenomenon caused by inconsistent speeds of the upper and lower straightening rollers. Gear positioning plate I and gear positioning plate II ensure the axial distance between the gears, and ensure that the gears mesh with each other to transmit power during the process of following the lifting and positioning frame.

[0013] 6) Centering and straightening: Hydraulic cylinder I pushes the upper support plate and the lifting and positioning frame downward along the direction of the support column. The lifting and positioning frame drives the straightening roller and the cleaning roller downward. The rack and gear on one side mesh with each other to form a centering mechanism, which drives the lower rack positioning plate and the lifting and positioning frame to move upward. The upper and lower lifting and positioning frames center and clamp the two sets of straightening rollers, ensuring that during the downward pressure straightening work, the upper and lower straightening rollers squeeze the stainless steel composite plate in the middle at the same time, so that the stainless steel composite plate is evenly stressed on both sides;

[0014] 7) Inspection: Motor IV drives the worm to rotate, and the worm drives the lower inspection roller to do reciprocating motion. Hydraulic cylinder II controls the inspection roller to press down so that the inspection roller is close to the surface of the stainless steel composite plate. At the same time, the sliding positioning frame and the transmission belt are connected by connecting the slider, so that the sliding positioning frame drives the transmission belt to rotate while doing reciprocating motion. The transmission belt drives the camera bracket and the CCD camera on the other side to do reciprocating motion as well. The CCD camera and the inspection roller are staggered. If the stainless steel composite plate has deformation such as buckle head, the deformation of the other side will be more serious because the inspection roller presses one side. The inspection is carried out by the CCD camera.
