Description

Technical Field

[0001] The utility model belongs to the technical field of hot-rolled plate straightening, in particular to a straightening device for hot-rolled plates of titanium and titanium alloys. Background Art

[0002] Titanium alloy hot-rolled plates are subjected to a variety of deformation forces under high temperature and high pressure. The forces that cause the deformation of titanium alloy hot-rolled plates include hot rolling force, the pressure exerted on the steel plate at high temperature, which causes it to extend and shrink to varying degrees in the longitudinal and transverse directions, and cooling shrinkage force. The steel plate shrinks due to the rapid loss of heat during the cooling process, which further aggravates the deformation of the steel plate, resulting in irregular deformations such as convex and concave curves in the titanium alloy hot-rolled plates after hot rolling; the hot-rolled plates still maintain a relatively high temperature after annealing, and the hot-rolled plates should be cooled again before entering the straightening mechanism to avoid temperature changes causing the hot-rolled plates to deform again; the presence of oxide scale and impurities will seriously affect the straightening effect and damage the straightening mechanism. The plate surface must be cleaned before straightening. Attention should be paid to the positioning of the plate during the straightening process to avoid poor straightening effect caused by oblique rolling, and the plate is then straightened through an adjustable straightening mechanism. The straightened plate is inspected by the detection device to ensure the straightening quality.

[0003] After searching, the prior art authorization publication number CN 115673036 A is a device for pressing and straightening steel plates before cutting, which includes a straightening machine and a base frame, etc.; a base frame is arranged on the right side of the straightening machine to realize the initial straightening of the steel plate, and then the steel plate is aligned by two top plates to avoid the steel plate from shifting during straightening, and then the impurities on the surface of the steel plate are adsorbed and removed, and the steel plate is straightened for the second time, and the burrs generated on the steel plate are scraped off at the same time, and then the steel plate is inspected; this device scrapes off the burrs generated on the edge of the steel plate by two scraping blocks, and makes the two second electric sliders move toward each other along the second electric slide rail, so that the two scraping blocks gather towards the middle of the steel plate, only scraping off the burrs on the edge of the steel plate, without scraping and cleaning the entire surface of the plate, and there is a risk that the scraped burrs are easily accumulated.

[0004] After searching, the prior art authorization publication number is CN 115673036 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 and drives 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, and then pushes the fixed frame downward, and the fixed block moves and is 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, and the displacement seat moves and drives the second straightening roller to move a distance, so as to facilitate the adjustment of 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; this device uses an adjustable lifting straightening device to straighten the plate, but no centering positioning mechanism is set, and the plate position cannot be positioned. During the straightening work, oblique rolling may occur, resulting in poor straightening effect, and the hidden danger of the plate misalignment causing the entire device to be stuck. No flatness detection device is set after straightening, and it is impossible to know whether the straightened plate is qualified. Utility Model Content

The spring III provides a buffer when pressing down, and the motor III drives the straightening rollers to rotate, giving the plate forward power during the straightening and leveling process;

[0018] 4) The motor IV of the centering and positioning mechanism drives the transmission belt II to rotate. The connecting frames on both sides of the transmission belt II perform centering movement, which drives the two sets of vertical side guide rollers to perform centering movement to ensure the centering and positioning of the plate, avoiding the problem of skew rolling affecting the straightening effect during the straightening process, and the problem of the mechanism being stuck due to plate misalignment;

[0019] 5) The motor V of the detection mechanism drives the detection pressure roller to move along the direction of the screw II, and the spring IV presses the roller frame downward to make the detection pressure roller fit the steel plate to be detected. When the steel plate to be detected is uneven, the steel plate touches the detection pressure roller upward, and the spring IV contracts the roller frame upward. The detection device detects the change in the roller frame position and detects whether the steel plate is flat. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] A straightening method for a titanium and titanium alloy hot-rolled plate straightening device, the specific method is as follows:

[0043] The titanium and titanium alloy hot-rolled plates first enter the cleaning mechanism 11. The spring I105 between the fixed plate 104 and the buffer plate 106 can adjust the gap between the upper and lower cleaning rollers 110, which is suitable for plates of different thicknesses. The motor I102 drives the upper cleaning roller 110 to rotate through the transmission belt I103. The upper cleaning roller 110 transmits power to the lower cleaning roller 110 through the engagement between the gear I111, the gear II113, and the gear III114 and the positioning of the two sets of gear connecting plates 112. The nozzle on the water pipe 1104 cooperates with the opening on the roller 1102 to soak the sponge sleeve 1101 on the periphery of the cleaning roller 110. The rotation of the two sets of cleaning rollers 110 can make the plate transported forward while wiping the surface of the titanium and titanium alloy hot-rolled plate, removing impurities on the surface of the plate and having the effect of cooling the plate.

[0044] The motor II 107 controls the slider 117 to slide along the lead screw I 109, and the slider 117 drives the circular scraper 108 to move. The inner diameter of the circular scraper 108 is slightly smaller than the outer diameter of the sponge sleeve 1101. During the movement of the circular scraper 108, the impurities adhered to the sponge sleeve 1101 can be scraped off, and the water in the sponge sleeve 1101 can be squeezed out, thereby playing the role of cleaning the sweeping roller 110; the scraping and blowing mechanism 12 presses one end of the connecting plate 202 downward through the spring II 204 between the spring positioning plate 205 and the connecting plate 202, and the connecting plate 202 drives the scraper positioning plate 203 to press downward, so that the multiple groups of inclined scrapers 210 in the scraper positioning plate 203 are close to the surface of the plate, scraping off the oxide scale and debris on the surface of the plate, and the scraper positioning plate 203 also drives the blowing head positioning plate 208 at the same time, so that the high-pressure blowing head 207 is parallel to the plate, blowing the scraped oxide scale and impurities off the plate, preventing the oxide scale and impurities from entering the subsequent leveling and straightening links, thereby ensuring the straightening quality;

[0045] Titanium and titanium alloy hot-rolled plates enter the straightening and leveling mechanism 13, and the hydraulic cylinder 301 controls the buffer plate 308 to press down. The buffer plate 308 presses down the upper straightening roller positioning frame 309 through four groups of springs III 311. The straightening roller positioning frame 309 drives the four groups of straightening rollers 310 to press down. At the same time, the upper connecting plates 303 on both sides of the buffer plate 308 drive the upper connecting rod 304 to press down. The upper connecting rod 304 drives the diamond plate 305 to rotate. The diamond plate 305 drives the lower connecting rod 304 to rise. The lower connecting rod 304 drives the lower connecting plate 307 to rise, so that the lower straightening roller positioning frame 309 drives the four groups of straightening rollers at the bottom. 310 rises, causing the upper and lower straightening rollers 310 to perform a centering squeezing action to improve the straightening efficiency. The spring III 311 between the buffer plate 308 and the upper straightening roller positioning frame 309 provides a buffer when pressing down. The motor III 314 drives the straightening roller 310 to rotate, giving the plate forward power during the straightening and leveling process; the motor IV 401 of the centering positioning mechanism 14 drives the transmission belt II 403 to rotate, and the connecting frames 405 on both sides of the transmission belt II 403 perform a centering movement, driving the two sets of vertical side guide rollers 406 to perform a centering movement, ensuring the centering positioning of the plate and avoiding the occurrence of skew rolling during the straightening process that affects the straightening effect;

[0046] The motor V501 controls the connecting slider I503 to slide along the lead screw II509, and the connecting slider I503 drives the positioning frame 504 below to move, and the positioning frame 504 drives the roller frame 507 and the detection roller 508 below to move; when the detection work is carried out, the motor V501 drives the detection roller 508 to move along the direction of the lead screw II509, and the two sides of the positioning frame 504 are connected to the connecting slider I503 and the connecting slider II511, because the lead screw II509 is connected to the limit shaft 5 10, the height of the positioning frame 504 will not change, and the height of the detection device 512 set on the L-shaped connecting plate 505 will not change. The spring IV 506 presses the roller frame 507 downward to make the detection roller 508 fit the steel plate to be detected. When the steel plate to be detected is uneven, the steel plate touches the detection roller 508 upward, and the spring IV 506 contracts the roller frame 507 upward. The detection device 512 detects the position change of the roller frame 507 and detects whether the steel plate is flat.
