Description

Technical Field

[0001] The invention belongs to the technical field of hot-rolled plate straightening, and in particular relates to a titanium and titanium alloy hot-rolled plate straightening device and a straightening method. 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 on the steel plate at high temperature, which causes it to produce different degrees of extension and contraction in the longitudinal and transverse directions, and cooling contraction 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 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 surface of the plate must be cleaned before straightening. During the straightening process, attention should be paid to the positioning of the plate to avoid poor straightening effect caused by oblique rolling, and then the plate is straightened through an adjustable straightening mechanism. The straightened plate is tested by the detection device to ensure the straightening quality.

[0003] After searching, the prior art authorization publication number CN 115673036 A is a steel plate pressing and straightening device 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 displacement of the steel plate 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 slide blocks move toward each other along the second electric slide rail, so that the two scraping blocks gather towards the middle of the steel plate, and only the burrs on the edge of the steel plate are scraped off, and the surface of the plate is not scraped and cleaned as a whole, and there is a risk that the scraped burrs are easily accumulated.

[0004] After searching, a steel plate straightening machine with the prior art authorization publication number CN 115673036 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 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, so as to adjust the distance between the upper and lower adjustment seats, thereby adjusting the distance between the straightening rollers, and then pushing the fixed frame downward, 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 movement of the displacement seat drives the second straightening roller to move a certain distance, so as to facilitate the adjustment of the upper and lower distances between 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, so the plate position cannot be positioned. During the straightening work, oblique rolling may lead to poor straightening effect, and there may be hidden dangers of the plate misalignment causing the device to be stuck as a whole. After straightening, no flatness detection device is set, so it is impossible to know whether the straightened plate is qualified. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a straightening device and a straightening method for hot-rolled plates of titanium and titanium alloys. The cleaning mechanism removes impurities on the surface of the plate and cools the plate, and can also clean the mechanism itself; the scraping and blowing mechanism can scrape off impurities such as oxide scale on the surface of the plate, and then blow them off with a high-pressure blowing head to avoid accumulation; the straightening mechanism can adjust the height of the mechanism according to the thickness of the plate to improve the straightening efficiency and straightening effect; the vertical side guide rollers of the centering and positioning mechanism can achieve centering clamping, position and center the plate, avoid adverse effects caused by oblique rolling, and mechanism jamming caused by misalignment; the detection mechanism can perform flatness detection on the straightened plate to ensure the straightening quality, and the plate that does not meet the flatness standard will be re-straightened.

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

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

[0008] 1) Cooling 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 the power to the lower cleaning roller through the meshing between the gears. The nozzle on the water pipe cooperates with the opening on the roller to soak the sponge sleeve on the outside of the cleaning roller. The two sets of cleaning rollers can wipe the surface of the titanium alloy hot-rolled plate and remove impurities on the surface of the plate.

[0009] 2) Scraping: The scraping and blowing mechanism uses springs to make the multiple groups of inclined scrapers in the scraper positioning plate close to the surface of the plate to scrape off the oxide scale and debris on the surface of the plate. The scraper positioning plate also makes the high-pressure blowing head parallel to the plate to blow off the scraped oxide scale and impurities from the plate to avoid the accumulation of oxide scale and impurities and enter the subsequent leveling and straightening process.

[0010] 3) Straightening and leveling: The hydraulic cylinder controls the four groups of straightening rollers to press down through the intermediate mechanism. At the same time, the four groups of straightening rollers at the bottom are driven up through the connecting rods on both sides of the straightening and leveling mechanism, so that the upper and lower straightening rollers are aligned and squeezed to improve the straightening efficiency. 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.

[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 plate.

[0012] 5) Detection: The motor V of the detection mechanism drives the detection roller to move along the direction of the screw II, and the spring IV presses down the roller frame to make the detection roller fit the steel plate to be detected. When the steel plate to be detected is uneven, the steel plate touches the detection roller upward, and the spring IV contracts the roller frame upward.
