Description

Technical Field

[0001] This invention belongs to the field of hot-rolled plate straightening technology, and specifically relates to a straightening device and straightening method for hot-rolled titanium and titanium alloy plates. Background Technology

[0002] Titanium alloy hot-rolled plates are subjected to various deformation forces under high temperature and high pressure. These forces include hot rolling force, pressure on the steel plate at high temperature causing varying degrees of elongation and contraction in the longitudinal and transverse directions, and cooling contraction force. During cooling, the steel plate shrinks due to rapid heat loss, further aggravating the deformation and resulting in irregular deformations such as convex and concave warping after hot rolling. Even after annealing, the hot-rolled plate maintains a high temperature. Before entering the straightening mechanism, the hot-rolled plate should undergo another cooling treatment to prevent further deformation due to temperature changes. The presence of oxide scale and impurities can severely affect the straightening effect and damage the straightening mechanism. Therefore, the plate surface must be cleaned before straightening. During the straightening process, attention must be paid to the plate positioning to avoid skew rolling, which would result in poor straightening. The plate is then straightened using an adjustable straightening mechanism. After straightening, the plate is inspected by a testing device to ensure straightening quality.

[0003] A search revealed a prior art patent, CN 115673036 A, for a steel plate pre-cutting and straightening device. This device includes a straightening machine and a base frame. The base frame is located on the right side of the straightening machine, enabling initial straightening of the steel plate. Two top plates then align the steel plate, preventing misalignment during straightening. Next, impurities on the steel plate surface are removed, and a second straightening process is performed. Simultaneously, burrs are scraped off, followed by inspection. However, this device uses two scrapers to remove burrs from the steel plate edges. Two second electric sliders move towards each other along a second electric slide rail, causing the scrapers to converge towards the center of the steel plate. This method only removes burrs from the steel plate edges, failing to clean the entire surface and posing a risk of burr accumulation.

[0004] A search revealed a steel plate straightening machine with prior art authorization publication number CN 115673036 A, which includes a base, with sliding grooves on both outer walls of the base, the sliding grooves communicating with the inner cavity of the base, a straightening roller provided in the inner cavity of the base, and also includes an adjustment mechanism and a displacement mechanism. By setting up adjustment and displacement mechanisms, rotating the rotating disk drives two movable seats to slide in the movable groove. The movement of the movable seats drives the adjustment seat to slide through the connecting rod, adjusting the distance between the upper and lower adjustment seats, thereby adjusting the distance between the straightening rollers. Then, the fixed frame is pushed down, and the fixed block moves and inserts into the fixed groove to fix the rotating disk. During this process, the pushing block moves and pushes the displacement seat to slide in the displacement groove. The movement of the displacement seat drives the second straightening roller to move a certain distance, which facilitates the adjustment of the upper and lower distance between the straightening rollers. When fixing the positions of the straightening rollers on both sides, 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 it does not have a centering and positioning mechanism, so it cannot position the plate. During the straightening process, there may be a risk of skew rolling leading to poor straightening effect, and plate misalignment causing the entire device to jam. After straightening, there is no flatness detection device, so it is impossible to know whether the straightened plate is qualified. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a straightening device and method for hot-rolled titanium and titanium alloy plates. The cleaning mechanism removes impurities from the plate surface and cools the plate, while also cleaning its own structure. The scraping and blowing mechanism scrapes off oxide scale and other impurities from the plate surface, which are then blown off by a high-pressure blower to prevent accumulation. The straightening mechanism can adjust its height according to the plate thickness, improving straightening efficiency and effect. The centering and positioning mechanism uses vertical side guide rollers for centering and clamping, positioning and centering the plate to avoid adverse effects caused by skew rolling and jamming caused by misalignment. The detection mechanism can detect the flatness of the straightened plate to ensure straightening quality; plates that do not meet the flatness standard are re-straightened.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A straightening method for a straightening device for hot-rolled titanium and titanium alloy plates, the specific steps of which are as follows:

[0008] 1) Cooling and cleaning: The motor I of the cleaning mechanism drives the upper cleaning roller to rotate through the transmission belt I. The upper cleaning roller transmits power to the lower cleaning roller through the meshing of gears. The nozzle on the water pipe cooperates with the opening on the roller to wet the sponge sleeve around the cleaning roller. The two sets of cleaning rollers can wipe the surface of the titanium alloy hot-rolled plate and remove impurities from the plate surface.

[0009] 2) Scraping: The scraping and blowing mechanism uses springs to bring multiple sets of inclined scrapers in the scraper positioning plate close to the surface of the board, scraping off the oxide scale and impurities on the surface of the board. At the same time, the scraper positioning plate also makes the high-pressure blower parallel to the board, blowing off the scraped oxide scale and impurities from the board, preventing the oxide scale and impurities from accumulating and entering the subsequent leveling and straightening stage.

[0010] 3) Straightening and leveling: The hydraulic cylinder controls the four sets of straightening rollers to press down through the intermediate mechanism. At the same time, the connecting rods on both sides of the straightening and leveling mechanism drive the four sets of straightening rollers at the bottom to rise, so that the upper and lower straightening rollers are aligned and squeezed to improve the straightening efficiency. Spring III provides a buffer when pressing down. Motor III drives the straightening rollers to rotate, giving the board forward power during the straightening and leveling process.

[0011] 4) Positioning and centering: The motor IV of the centering and positioning mechanism drives two sets of vertical side guide rollers to perform centering movement through the transmission belt II, ensuring the centering and positioning of the board.

[0012] 5) Inspection: Motor V of the inspection mechanism drives the inspection roller to move along the direction of screw II. Spring IV presses down the roller frame to make the inspection roller fit against the steel plate to be inspected. When the steel plate to be inspected is not flat, the steel plate touches the inspection roller and moves upward. Spring IV retracts the roller frame and moves upward. The inspection device detects the change in the position of the roller frame and detects whether the steel plate is flat.

[0013] A straightening device for hot-rolled titanium and titanium alloy plates includes a cleaning mechanism, a scraping and blowing mechanism, a straightening and leveling mechanism, a centering and positioning mechanism, a detection mechanism, and a housing; the cleaning mechanism, scraping and blowing mechanism, straightening and leveling mechanism, centering and positioning mechanism, and detection mechanism are arranged sequentially from front to back in the housing.

[0014] The cleaning mechanism includes a motor mounting plate, a motor I, a transmission belt I, a fixed plate, a spring I, a buffer plate, a motor II, a circular scraper, a lead screw I, a cleaning roller, a gear I, a gear connecting plate, a gear II, a gear III, a hose, a water pump, and a slider. Multiple sets of springs I are provided between the fixed plate and the buffer plate, connecting them. The motor II is mounted on the buffer plate and connected to the lead screw I. The slider is slidably connected to the lead screw I. A circular scraper is connected below the slider, and a cleaning roller is located inside the scraper. The cleaning roller is connected to the water pump via a hose. The motor mounting plate is mounted on the upper fixed plate, and the motor I is mounted on the motor mounting plate. The motor I is connected to the transmission belt I. The upper cleaning roller is connected to a gear I at one end. Gear I is connected to a gear connecting plate and meshes with gear II. Gear II meshes with gear III. Gear II also connects to both upper and lower gear connecting plates. Gear III connects to the lower cleaning roller. Motor I drives the upper cleaning roller to rotate through transmission belt I. The upper cleaning roller rotates through the meshing of gears I, II, and III. The distance between the gears is ensured by the two gear connecting plates, ensuring that power can be transmitted from the upper cleaning roller to the lower cleaning roller. Motor II controls the slider and the circular scraper under the slider to move along the lead screw I. The circular scraper can scrape and clean the cleaning roller.

[0015] The cleaning roller includes a sponge sleeve, a roller, an arc-shaped support plate, a water pipe, a rotary connector, and a central shaft. The arc-shaped support plate has six sets, which are distributed equidistantly in a circle on the central shaft. Two sets of water pipes are provided in the gap between the arc-shaped support plates. A rotary connector is provided on one side of the water pipe. The nozzle on the water pipe matches the opening on the roller. A sponge sleeve is fitted on the outside of the roller.

[0016] The scraping and blowing mechanism includes a positioning plate, a connecting plate, a scraper positioning plate, a spring II, a spring positioning plate, a limiting plate, a high-pressure blower head, a blower head positioning plate, an air pipe, and an oblique scraper. The positioning plate and the connecting plate are connected by a central pin. One end of the connecting plate is connected to the scraper positioning plate, and the other end is located inside the limiting plate. The spring positioning plate is fixed on the positioning plate and has multiple sets of spring II, which are also connected to the connecting plate. Multiple sets of oblique scrapers are located inside the scraper positioning plate. The upper scraper positioning plate is also connected to the blower head positioning plate, which has a high-pressure blower head. The high-pressure blower head is connected to the air pipe via a flexible hose.

[0017] The straightening and leveling mechanism includes a hydraulic cylinder, a hydraulic cylinder mounting plate, an upper connecting plate, a connecting rod, a rhombus-shaped plate, a rotating shaft, a lower connecting plate, a buffer plate, a straightening roller positioning frame, a straightening roller, spring III, support columns, a base plate, and a motor III. Four sets of support columns are provided between the hydraulic cylinder mounting plate and the base plate. From top to bottom, a buffer plate and two sets of straightening roller positioning frames are arranged between the hydraulic cylinder mounting plate and the base plate, symmetrically distributed. The hydraulic cylinder is mounted on the hydraulic cylinder mounting plate, and its lower part is connected to the buffer plate to control its rise and fall. A straightening roller positioning frame is located below the buffer plate, connected to it by four sets of springs III. Four sets of straightening rollers are housed within the straightening roller positioning frame. Two sets of upper connecting plates are also provided on both sides of the buffer plate. The upper connecting plates are connected to the connecting rod via pins, and the connecting rods are connected to the rhombus-shaped plate via pins. A rotating shaft is located at the center of the rhombus-shaped plate. The rotating shaft is rotatably connected to the housing. The lower straightening roller positioning frame has lower connecting plates at both ends. The lower connecting plates are connected to the lower connecting rods via pins. The lower connecting rods are connected to the diamond-shaped plates via pins. The four sets of straightening rollers are connected by a transmission belt. The connected straightening rollers are controlled to rotate by motor III. The hydraulic cylinder controls the buffer plate to press down. The buffer plate presses down the upper straightening roller positioning frame via four sets of springs III. The straightening roller positioning frame drives the four sets of straightening rollers to press down. At the same time, the upper connecting plates on both sides of the buffer plate drive the upper connecting rods to press down. The upper connecting rods drive the diamond-shaped plates to rotate. The diamond-shaped plates drive the lower connecting rods to rise. The lower connecting rods drive the lower connecting plate to rise. Thus, the lower straightening roller positioning frame drives the four sets of straightening rollers to rise. This makes the upper and lower straightening rollers center and squeeze, improving straightening efficiency. The springs III between the buffer plate and the upper straightening roller positioning frame provide cushioning during the downward pressure.

[0018] The centering and positioning mechanism includes a motor IV, a transmission belt positioning plate, a transmission belt II, a positioning shaft, a connecting frame, vertical side guide rollers, and a positioning shaft fixing plate. The motor IV is mounted on the transmission belt positioning plate and connected to the transmission belt II. There are two sets of connecting frames, one of which is connected to the transmission belt II on one side, and the other set of connecting frames is connected to the transmission belt II in the opposite position to the first set. The distances of the two sets of connecting frames from the center of the transmission belt positioning plate are equal. There are also two sets of positioning shaft fixing plates at both ends of the transmission belt positioning plate, and two sets of positioning shafts are provided between the two sets of positioning shaft fixing plates. The connecting frame is slidably connected to the positioning shaft, and the connecting frame is also provided with a vertical side guide roller. The motor IV drives the transmission belt II to rotate, and the connecting frames on both sides of the transmission belt II perform centering movement, which in turn drives the two sets of vertical side guide rollers to perform centering movement.

[0019] The detection mechanism includes a motor V, a support platform, a connecting slider I, a positioning frame, an L-shaped connecting plate, spring IV, a roll frame, a detection pressure roller, a lead screw II, a limit shaft, a connecting slider II, and a detection device; the motor V is connected to the lead screw II, the connecting slider I is slidably connected to the lead screw II, the connecting slider I is located at one end of the positioning frame, and the other end of the positioning frame is provided with the connecting slider II, which is slidably connected to the limit shaft. An L-shaped connecting plate is located in the middle of the positioning frame, connecting the detection device. The roll frame is located in a groove at the bottom of the positioning frame and is slidably connected to the positioning frame. Two sets of spring IV are located between the positioning frame and the roll frame. A detection pressure roller is located inside the roll frame, and a support platform is located below the detection pressure roller; the motor... Motor V controls the sliding of connecting slider I along lead screw II. Connecting slider I drives the positioning frame below to move, and the positioning frame drives the rolling frame and the detection roller below to move. When the detection work is performed, motor V drives the detection roller to move along lead screw II. Connecting slider I and connecting slider II are connected on both sides of the positioning frame. Because of the limit of lead screw II and limit shaft, the height of the positioning frame will not change, and the height of the detection device set on the L-shaped connecting plate will not change. Spring IV presses down the rolling frame, so that the detection roller is close to the steel plate to be detected. When the steel plate to be detected is not flat, the steel plate touches the detection roller and moves upward. Spring IV retracts the rolling frame and moves upward. The detection device detects the change in the position of the rolling frame and detects whether the steel plate is flat.

[0020] The advantages of this invention compared to existing technologies are as follows:

[0021] 1) The motor I of the cleaning mechanism drives the upper cleaning roller to rotate through the transmission belt I. The upper cleaning roller transmits power to the lower cleaning roller through the meshing of gears. The sponge sleeve around the cleaning roller is moistened by water pipe. The two sets of cleaning rollers can wipe the surface of the titanium alloy hot-rolled plate, remove impurities from the plate surface and cool the plate.

[0022] 2) Motor II controls the slider to slide along lead screw I. The slider drives the circular scraper to move. The inner diameter of the circular scraper is slightly smaller than the outer diameter of the sponge sleeve. During the movement of the circular scraper, the impurities adhering to the sponge sleeve can be scraped off and the water inside the sponge sleeve can be squeezed out, which plays the role of cleaning the cleaning roller and prevents the cleaning roller from losing its function of cleaning the surface of the board after being contaminated for a long time.

[0023] 3) The scraping and blowing mechanism uses springs to keep multiple sets of inclined scrapers in the scraper positioning plate close to the surface of the board, scraping off the oxide scale and impurities on the surface of the board. At the same time, the scraper positioning plate also makes the high-pressure blower parallel to the board, blowing off the scraped oxide scale and impurities from the board, preventing the oxide scale and impurities from accumulating and entering the subsequent leveling and straightening stage, thus ensuring the straightening quality. The hydraulic cylinder controls the four sets of straightening rollers to press down through the intermediate mechanism, and at the same time drives the four sets of straightening rollers at the bottom to rise through the connecting rods on both sides of the straightening and leveling mechanism, so that the upper and lower straightening rollers are centered and squeezed, improving the straightening efficiency. Spring III provides a buffer during the downward pressure, and motor III drives the straightening rollers to rotate, giving the board forward power during the straightening and leveling process.

[0024] 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. This avoids the problem of skew rolling affecting the straightening effect during the straightening process, as well as the problem of the mechanism jamming due to plate misalignment.

[0025] 5) The motor V of the detection mechanism drives the detection pressure roller to move along the direction of the lead screw II. The spring IV presses down the roller frame so that the detection pressure roller is in contact with the steel plate to be detected. When the steel plate to be detected is not flat, the steel plate touches the detection pressure roller and moves upward. The spring IV retracts the roller frame and moves upward. The detection device detects the change in the position of the roller frame and detects whether the steel plate is flat. Attached Figure Description

[0048] A straightening method for a straightening device for hot-rolled titanium and titanium alloy plates, the specific method is as follows:

[0049] The hot-rolled titanium and titanium alloy plates first enter the cleaning mechanism 11. The spring I 105 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 I 102 drives the upper cleaning roller 110 to rotate through the transmission belt I 103. The upper cleaning roller 110 transmits power to the lower cleaning roller 110 through the meshing between gears I 111, gear II 113, and gear III 114 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 wet the sponge sleeve 1101 around the cleaning roller 110. The rotation of the two sets of cleaning rollers 110 can make the plate forward while wiping the surface of the hot-rolled titanium and titanium alloy plates, removing impurities from the plate surface and cooling the plate.

[0050] Motor II 107 controls slider 117 to slide along lead screw I 109. Slider 117 drives circular scraper 108 to move. The inner diameter of circular scraper 108 is slightly smaller than the outer diameter of sponge sleeve 1101. During the movement of circular scraper 108, impurities adhering to sponge sleeve 1101 can be scraped off and water inside sponge sleeve 1101 can be squeezed out, thus cleaning the cleaning roller 110. Scraping and blowing mechanism 12 uses spring II 204 between spring positioning plate 205 and connecting plate 202 to press one end of connecting plate 202 downward. Connecting plate 202 drives scraper positioning plate 203 to press downward, so that multiple sets of inclined scrapers 210 in scraper positioning plate 203 are close to the surface of the board, scraping off the oxide scale and impurities on the surface of the board. Scraper positioning plate 203 also drives blow head positioning plate 208, so that high pressure blow head 207 is parallel to the board, blowing off the scraped oxide scale and impurities from the board, preventing oxide scale and impurities from entering the subsequent leveling and straightening process, and ensuring the straightening quality.

[0051] Hot-rolled titanium and titanium alloy plates enter the straightening and leveling mechanism 13. Hydraulic cylinder 301 controls the buffer plate 308 to press down. The buffer plate 308, through four sets of springs Ⅲ 311, causes the upper straightening roller positioning frame 309 to press down. The straightening roller positioning frame 309 drives the four sets of straightening rollers 310 to press down. Simultaneously, 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, thereby causing the lower straightening roller positioning frame 309 to drive the lower four sets of straightening rollers. The upward movement of roller 310 causes the upper and lower straightening rollers 310 to center and squeeze, improving straightening efficiency. The spring Ⅲ 311 between the buffer plate 308 and the upper straightening roller positioning frame 309 provides cushioning during downward pressure. The motor Ⅲ 314 drives the straightening roller 310 to rotate, providing forward power to the plate during the straightening and leveling process. The motor Ⅳ 401 of the centering and positioning mechanism 14 drives the transmission belt Ⅱ 403 to rotate. The connecting frames 405 on both sides of the transmission belt Ⅱ 403 perform centering movement, driving the two sets of vertical side guide rollers 406 to perform centering movement, ensuring the centering and positioning of the plate and avoiding skew rolling during the straightening process, which affects the straightening effect.

[0052] Motor V501 controls the sliding of connecting slider I 503 along lead screw II 509. Connecting slider I 503 drives the lower positioning frame 504 to move, which in turn drives the lower roller frame 507 and the detection roller 508 to move. During detection, motor V501 drives the detection roller 508 to move along lead screw II 509. The positioning frame 504 connects connecting slider I 503 and connecting slider II 511 on both sides. Because lead screw II 509 and limit shaft 5... The height of the positioning frame 504 will not change when the limit is set at 10, and the height of the detection device 512 set on the L-shaped connecting plate 505 will also not change. The spring IV 506 presses down the roller frame 507, so that the detection roller 508 is in contact with the steel plate to be tested. When the steel plate to be tested is not flat, the steel plate touches the detection roller 508 and moves upward. The spring IV 506 retracts the roller frame 507 and moves upward. The detection device 512 detects the change in the position of the roller frame 507 and detects whether the steel plate is flat.
