In order to solve the technical problem that the steel belt quality is influenced by overlarge stress on the surface of the steel belt in the deviation rectifying process in the prior art, the application provides a full-automatic deviation rectifying device.
Referring to fig. 1 to 3, the full-automatic deviation rectifying device includes a swing frame 10, a carrier roller 20, and an angle adjuster 30.
The housing 10 is rotatably fixed to a base (not shown), and the center of rotation of the housing 10 is located on the reference center line of the steel strip 200. Specifically, the frame 10 is fixed to the base through a hinge. The steel strip standard center line is a center line of a preset steel strip standard position, and when the steel strip 200 does not deviate, the steel strip 200 is located at the steel strip standard position.
The frame 10 is substantially in the shape of a long strip, and the length of the frame 10 is greater than the width of the steel strip. Two ends of the frame 10 are provided with lugs 11, and the lugs 11 are provided with fixing holes.
Both ends of the idler 20 are rotatably provided to the frame 10. Specifically, both ends of the idler 20 are rotatably disposed in the fixing holes of the lugs 11. The idler 20 is in contact with the lower surface of the steel strip. When the steel belt is positioned at the standard position of the steel belt, the axis direction of the carrier roller 20 is perpendicular to the running direction of the steel belt.
The angle adjuster 30 includes a base plate 31, two fixing plates 34, a slider 32, and two elastic members 33. The bottom plate 31 is fixed on the base, the two fixing plates 34 are fixed on the bottom plate 31 oppositely, the sliding seat 32 is located between the two fixing plates 34, and the two elastic members 33 are located at two ends of the sliding seat 32 respectively and located between the fixing plates 34 and the sliding seat 32. The slide 32 is fixed to the frame 10.
Furthermore, each fixing plate 34 is provided with a through hole, an adjusting screw 35 is arranged in the through hole, and one end of the adjusting screw 35 penetrates through the through hole of the fixing plate 34 and then is arranged in the elastic element 33. By adjusting the adjusting bolt 35, the acting force of the elastic member 33 on the sliding base 32 can be adjusted, thereby adjusting the magnitude of the deviation rectifying force.
Specifically, in the present embodiment, the elastic member 33 is specifically a spring, and in other embodiments, the elastic member 33 may be an elastic sheet or the like. The slide 32 is provided with a fixing column in a protruding manner, and the slide 32 is fixed on the rack 10 through the fixing column.
In the specific use process, a plurality of parallel full-automatic deviation rectifying devices can be arranged on the same base, and the deviation rectifying devices can rectify the deviation of different positions of the strip steel.
When the strip steel passes through the standard position of the strip steel, the moment at the two ends of the carrier roller 20 is equal, the carrier roller 20 is kept perpendicular to the running direction of the strip steel under the action of the angle adjuster 30, at the moment, the sliding seat 32 is at the initial position, and the pressures of the elastic pieces 33 at the two ends are equal.
As shown in fig. 4, once the steel belt deviates, the contact length between the carrier roller 20 at the deviation end and the steel belt is increased by taking the central axis as a reference, the torque difference between the two ends of the carrier roller 20 generates a swing torque, the forward torque of the deviation end of the carrier roller 20 is greater than that of the other end, so that the carrier roller 20 deflects, and meanwhile, the slide seat 32 extrudes the elastic member 33 on the angle adjuster 30 at the deviation end, so that the elastic members 33 at the two ends form a pressure difference, the pressure difference gradually increases along with the increase of the swing angle, and after the carrier roller 20 deflects, the frame 10 deflects along with the carrier roller 20.
When the swing amount reaches a certain angle, the swing torque and the pressure difference of the elastic member 33 reach equilibrium, and the frame 10 stops swinging. The deflected carrier roller 20 pulls the steel belt back to the central position by generating a transverse force, and after the steel belt returns to the central position, the moment at the two ends of the carrier roller 20 is the same, and the carrier roller 20 automatically returns to the initial position again under the action of the elastic member of the angle regulator 30. After the sensitivity of the angle regulator 30 and the angle of the carrier roller 20 are initially set, the automatic adjustment is completely realized by the mechanism in the production process, and the purpose of automatic deviation correction is achieved.
The full-automatic deviation correcting device of this application is in unit production process, and the steel band position is adjusted by oneself completely. The angle of the carrier roller and the deviation correcting sensitivity can be adjusted according to the field condition and the product performance before production. The purpose of deviation correction is achieved by the automatic rotation of the carrier roller without manual intervention during work.
The method can be widely applied to the production lines of the strip steels such as cold rolling continuous annealing, coating, silicon steel and the like, the correction of the splayed roller which is widely adopted originally is fundamentally improved, the correction process only generates single correction force, the method is more reliable, the surface of the effective strip steel generates wrinkles or yield lines, and the product quality is greatly improved. Meanwhile, the deviation correcting reliability is greatly improved, the probability of edge scraping and belt breakage of the unit is reduced, waste products are reduced, and the reliability and the yield of the unit are greatly improved.
The angle regulator adopts the design of adjustable spring, can adapt to various product needs, even production raw materials is frequently changed to the production line, also can adapt to new raw materials requirement fast, can adjust on line even, realizes not shutting down of reloading. The whole deviation rectifying process is completely and automatically adjusted, manual intervention is not needed, the whole structure is simple and reliable, and efficient and safe production of the unit can be realized only with lower cost. The scheme can also enable the unit to obtain higher production speed, and because product defects are avoided to a great extent, the probability of scraping edges and breaking belts is reduced, and the deviation of the unit can not occur under the conditions of high-speed and long-distance operation.
