Description

Technical Field

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

[0002] During 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 likely to hit the roller body, and in severe cases, a "roller wrapping" 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 temperature differences. 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 and buckle 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 CN 118106353 A is a stainless steel production rolling mill, which includes a hollow plate, the four corners of the bottom of the hollow plate are fixedly connected to support columns, and the right side of the outer wall of the hollow plate is fixedly connected to a first support plate. It also includes an adjustment mechanism, and the ends of the two lifting blocks close to each other are both sleeved and rotatably connected to the lifting rod. During operation, 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. If the rolling line height is too high or too low, the front end will be unevenly stressed, resulting in asymmetric rolling and buckling of the workpiece.

[0004] After searching, the prior art authorization publication number is CN 118635307 A, which is a steel plate straightening machine, including a base, both sides of the outer wall of the base are provided with a slide groove, the slide groove is connected to the inner cavity of the base, the inner cavity of the base is provided with a straightening roller, and also includes an adjustment mechanism and a displacement mechanism. By setting an adjustment mechanism and a displacement mechanism, the rotating disk drives the two movable seats to slide in the movable groove, and the movable seat moves to drive the adjustment seat to slide through the connecting rod, and adjusts the distance between the upper and lower adjustment seats, 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 to push the displacement seat to slide in the displacement groove, and the displacement seat moves to drive the second straightening roller to move a distance, which is convenient for adjusting the upper and lower spacing 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.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1) Motor I of the centering conveying mechanism controls the vertical guide rollers between the two sets of sliding guide plates to center and clamp the stainless steel composite plate. As a result, the vertical guide rollers center and clamp the two sides of the stainless steel composite plate during the conveying process, playing a role in centering and positioning. The temperature chamber and insulation cover ensure that the temperature of the stainless steel composite plate remains stable during the conveying process, preventing large temperature fluctuations. The centering conveying mechanism centers and positions the plate while conveying it. The upper and lower insulation chambers and insulation covers ensure that the plate maintains temperature during the conveying process, avoiding the problem of buckling caused by large temperature fluctuations.

[0014] 2) The motor II of the cleaning guide mechanism drives the two sets of bidirectional screws to rotate through the meshing between the transmission shaft I and the two sets of helical gears, so that the two sets of lifting plates and the buffer plate I provided on the bidirectional screws I and II are aligned and clamped, driving the inclined scraper to descend. The tension spring tightens the inclined scraper so that its lower end contacts the surface of the stainless steel composite plate, scraping off impurities such as oxide scale on the surface of the stainless steel composite plate. The spring I acts as a buffer, and the scraped oxide scale is blown off through the air blower to prevent accumulation.

[0015] 3) The lifting plate drives the guide roller positioning frame and the guide roller to descend at the same time. 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 clamped in the center by the guide rollers regardless of whether it is warped or buckled, avoiding the mechanism jamming caused by the plate warping and buckling, increasing work efficiency and preparing for subsequent straightening work;

[0016] 4) The hydraulic cylinder I of the straightening mechanism 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 align and clamp the two sets of straightening rollers, ensuring that during the downward straightening work, the upper and lower straightening rollers squeeze the middle stainless steel composite plate at the same time, so that the force on both sides of the stainless steel composite plate is evenly applied, avoiding the phenomenon of buckled heads;

[0017] 5) The motor III of the straightening mechanism drives the 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 the consistent speeds of the two groups of straightening rollers, avoiding the recurrence of the buckle head phenomenon caused by inconsistent speeds of the upper and lower straightening rollers. The gear positioning plates I and II ensure the axial distance between the gears. In the process of following the lifting and positioning frame, the gears are meshed with each other to transmit power. Gear I and Gear VII drive the two groups of cleaning rollers to rotate, cleaning impurities stuck on the straightening rollers, avoiding poor straightening results caused by impurities stuck on the straightening rollers;

[0018] 6) The motor IV of the detection mechanism drives the worm to rotate, and the worm drives the lower detection roller to do reciprocating motion. The hydraulic cylinder II controls the detection roller to press down so that the detection 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 through the connecting 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 detection 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 detection roller presses one side. At this time, the CCD camera is used for detection. The angle stepper motor controls the rotation angle of the CCD camera as needed to re-straighten the plate with poor straightening effect to ensure the straightening effect.

[0042] A buckle head control device for rolling stainless steel composite plates. The specific use process of the device is as follows:

[0043] The motor I 107 of the centering conveying mechanism 11 controls the vertical guide rollers 108 between the two sets of sliding guide plates 104 to center and clamp the stainless steel composite plate. As a result, the vertical guide rollers 108 center and clamp both sides of the stainless steel composite plate during the conveying process, playing a role in centering and positioning. The heat-insulating cabin 101 and the heat-insulating cover 109 keep the temperature of the stainless steel composite plate stable during the conveying process, and there will be no large temperature difference.

[0044] The motor II 201 of the cleaning guide mechanism 12 is engaged with the two sets of helical gears through the transmission shaft I 202, driving the two sets of bidirectional screws to rotate, so that the two sets of lifting plates 220 and the buffer plate I 208 arranged on the bidirectional screw I 207 and the bidirectional screw II 221 are centered and clamped, driving the inclined scraper 214 to descend, and the tension spring 212 tightens the inclined scraper 214 so that its lower end is in contact with the surface of the stainless steel composite plate, scraping off impurities such as oxide scale on the surface of the stainless steel composite plate, and the spring I 209 plays a buffering role. The scraped oxide scale is blown off by the air blow pipe 211 to prevent accumulation. The lifting plate 220 also drives the guide roller positioning frame 218 and the guide roller 219 to descend. The front ends of the upper and lower guide roller positioning frames are arc-shaped, and the guide roller 219 is arranged in the guide roller positioning frame 218 to ensure that the stainless steel composite plate is warped or buckled, and is centered and clamped by the guide roller 219 to avoid the mechanism from being stuck due to the warping and buckling of the plate, thereby increasing work efficiency and preparing for subsequent straightening work;

[0045] The hydraulic cylinder I 301 of the straightening mechanism 13 pushes the upper support plate 302 and the lifting and positioning frame 303 downward along the direction of the supporting column 304, and the lifting and positioning frame 303 drives the straightening roller 307 and the cleaning roller 306 to press down. The rack and gear on one side engage with each other to form a centering mechanism, which drives the lower rack positioning plate 321 and the lifting and positioning frame 303 to move upward. The upper and lower sets of lifting and positioning frames 303 center and clamp the two sets of straightening rollers 307, ensuring that during the downward straightening work, the upper and lower straightening rollers 307 squeeze the middle stainless steel composite plate at the same time, so that the force on both sides of the stainless steel composite plate is evenly distributed, avoiding the buckle head phenomenon; the motor III 308 of the straightening mechanism 13 is connected to the gear The meshing between them drives the seven sets of teeth from gear I 309 to gear VII 315 to rotate, ensuring that the rotation speed of gear II 310 and gear VI 314 is consistent, thereby ensuring that the rotation speed of the two sets of straightening rollers 307 is consistent, avoiding the recurrence of the buckle head phenomenon caused by inconsistent rotation speeds of the upper and lower straightening rollers 307, and gear I 309 and gear VII 315 drive the two sets of cleaning rollers 306 to rotate, clean the impurities adhering to the straightening rollers 307, and avoid poor straightening effect caused by impurities adhering to the straightening rollers 307. Gear positioning plate I 316 and gear positioning plate II 317 ensure the axial distance between the gears, and ensure that the gears are engaged with each other to transmit power in the process of following the lifting and positioning frame.

[0046] The motor IV 401 of the detection mechanism 14 drives the worm 402 to rotate, and the worm 402 drives the lower detection roller 410 to do reciprocating motion. The hydraulic cylinder II 407 controls the detection roller 410 to press down so that the detection roller 410 is close to the surface of the stainless steel composite plate. At the same time, the sliding positioning frame 406 and the transmission belt 412 are connected through the connecting slider 411, so that the sliding positioning frame 406 drives the transmission belt 412 to rotate while doing reciprocating motion. The transmission belt 412 drives the camera bracket 417 and the CCD camera 418 on the other side to do reciprocating motion as well. The CCD camera 418 is staggered with the detection roller 410. If the stainless steel composite plate has deformation such as buckled heads, the deformation of the other side will be more serious because the detection roller 410 presses one side. At this time, it is detected by the CCD camera 418, and the angle stepping motor 419 controls the rotation angle of the CCD camera 418 as needed to re-straighten the plate with poor straightening effect, improve the detection efficiency, and ensure the straightening effect.
