[0002] With the development of industry, high-strength steel plates are being used more and more widely in various fields. In the process of metal processing, due to various factors such as cutting, welding and heat treatment, metal plates may produce internal stress and unevenness problems, which will affect the subsequent processing and use of metal plates. Therefore, they need to be corrected by leveling devices. However, high-strength steel plates have high hardness and strength. Traditional leveling devices may encounter difficulties such as difficult feeding and poor leveling effects when processing them. In order to solve the leveling problem of high-strength steel plates, multi-stage adjustable technology is introduced into the leveling device. This technology allows the leveling device to adjust the pressure and arrangement of the leveling rollers in different sections according to the actual situation of the steel plate, so as to achieve multi-stage and fine leveling of the steel plate; Most operations of existing metal leveling devices during the processing are manually controlled, and the leveling accuracy and pressure distribution cannot be guaranteed. Due to the high strength and rigidity of high-strength steel plates, traditional leveling devices cannot meet processing requirements. During the leveling process, the steel plates are repeatedly pulled up to achieve a flat effect, which may cause excessive cold work hardening and reduce the service life of the steel plates.

Based on the laser triangulation method, the laser displacement sensor 12 emits a very thin laser beam through the internal laser diode. This light beam hits the surface of the steel plate with extremely high linearity and concentration.

The support shaft 3 moves upward to drive the contact block 15 to move to adjust the depression on the surface of the steel plate. Facing the protrusion on the surface of the steel plate, the moving unit 14 drives the contact block 15 to move above the protrusion. After the support shaft 3 moves downward to contact the surface of the steel plate, it continues to move downward to flatten the protrusion. Multiple contact blocks 15 work simultaneously to level the steel plate, realizing the function of fixed-point leveling of the steel plate, solving the problems of small-scale unevenness, poor leveling effect and the need for subsequent processing during the leveling process, which can improve the leveling quality of the steel plate, improve the processing efficiency of the device, reduce the cost of manual processing and device maintenance, and improve the economic benefit of the device.

Based on the relationship between the mechanical properties and electrical properties of the material, when an object is subjected to an external force, stress or strain will be generated inside it, causing changes in electrical parameters such as resistance, capacitance and inductance of the material. The resistance value of the steel plate is measured by the resistance strain gauge and the processing circuit, and the stress inside the steel plate is inferred by the change in resistance value. The data information is transmitted to the controller 9. After being compared with the preset safety value range, if the internal stress of the steel plate is too large, it will affect the subsequent leveling. The controller 9 controls the leveling motor 11 to drive the first moving pulley 19 to move the first rotating shaft 6 to the side of the steel plate to be leveled. The first rotating shaft 6 rotates the first telescopic rod 20 and the heating nozzle 18 to the top of the steel plate.

Based on the physical characteristics of infrared radiation, any object with a temperature higher than absolute zero will radiate infrared rays outward, and the higher the temperature of the object, the more infrared rays are radiated. The infrared rays radiated by the steel plate are converted into electrical signals through the optical system and the photoelectric detector. After being processed by the signal amplifier and the A / D converter, the temperature of the steel plate is measured and transmitted to the controller 9. The temperature of the heating point is accurately controlled, and subsequent leveling processing is performed after the temperature returns to normal temperature. The function of eliminating the internal stress of the steel plate before leveling the steel plate is realized, and the problems of poor leveling effect, reduced service life of the steel plate and potential safety hazards caused by uneven and excessive internal stress of the steel plate are solved.

[0030] Working principle: the conveying motor 32 drives the conveyor belt 4 to transport the steel plate to the processing table 2 by rotating the pulley 30. After the steel plate moves to the position, the controller 9 controls the fixer 31 to fix the steel plate. The controller 9 controls the second rotating shaft 22 to rotate the second telescopic rod 29 and the brush head 25 and the cleaning nozzle 24 at the end thereof to the top of the steel plate. The second telescopic rod 29 brings the brush head 25 close to the steel plate. The controller 9 controls the water valve 27 to connect the cleaning nozzle 24 and the water tank 26. The cleaning motor 23 drives the second movable pulley 28 to move. The brush head 25 and the cleaning nozzle 24 move back and forth on the surface of the steel plate driven by the second movable pulley 28 to clean the steel plate and remove dirt on the surface of the steel plate. Before leveling the steel plate, the stress sensor 21 calculates the stress inside the steel plate through the change of the resistance value, and transmits the data information to the controller 9. After comparing with the preset safety value range, the internal stress of the steel plate is too large, which will affect the subsequent leveling. The controller 9 controls the leveling motor 11 to drive the first moving pulley 19 to move the first rotating shaft 6 to the side of the steel plate to be leveled. The first rotating shaft 6 rotates the first telescopic rod 20 and the heating nozzle 18 to the top of the steel plate. Through the back and forth extension of the first telescopic rod 20, the heating nozzle 18 is moved back and forth on the upper side of the steel plate for uniform heating. The temperature sensor 16 measures the temperature of the steel plate and transmits the temperature to the controller 9 to accurately control the temperature of the heating point, and waits for the temperature to return to normal temperature before performing subsequent leveling processing; The laser displacement sensor 12 transmits the distance signal between the steel plate and the sensor to the controller 9. The controller 9 analyzes the flatness of the steel plate surface according to the information transmitted by the laser displacement sensor 12. When a depression appears on the steel plate surface, the controller 9 controls the contact block 15 to move above the depression of the steel plate under the drive of the moving unit 14. The controller 9 controls the support shaft 3 to descend and drive the contact block 15 to move downward. According to the information transmitted by the laser displacement sensor 12, the controller 9 moves until the contact block 15 contacts the steel plate surface. The controller 9 activates the magnetic unit 13 to tightly adsorb the contact block 15 to the steel plate. The support shaft 3 moves upward to drive the contact block 15 to move and adjust the depression on the steel plate surface. , facing the protrusion on the surface of the steel plate, the moving unit 14 drives the contact block 15 to move above the protrusion, and after the support shaft 3 moves down to contact the surface of the steel plate, it continues to move down to flatten the protrusion, and multiple contact blocks 15 work simultaneously to level the steel plate. If the steel plate is a non-magnetic steel plate such as stainless steel, after leveling the protrusion on the surface of the steel plate, the fixer 31 fixes the steel plate, and the conveying motor 32 drives the conveyor belt 4 to transport the steel plate to the bottom of the processing table. The controller 9 controls the fixer 31 to release the fixation of the steel plate. After the steel plate is turned over, it is transported to the processing table 2 again through the conveyor belt 4, and the fixer 31 fixes the steel plate for the second time, and the leveling module 10 performs secondary leveling on the steel plate; After the leveling module 10 completes leveling of the steel plate, the controller 9 controls the moving unit 14 to move the grinding assembly 33 to the uneven part of the steel plate processed by the leveling module 10, the support shaft 3 descends, and the grinding head 35 is close to the steel plate to grind the processed uneven part, the spray head 37 sprays the grinding liquid stored in the liquid storage tank 36 on the steel plate, the leveling motor 11 drives the rotating head 34 to rotate, and the grinding head 35 follows the rotation of the rotating head 34 to grind the steel plate, during the grinding process, the switch 38 switches the mesh number of the grinding head 35, and the grinding head 35 switches from 80 mesh to 180 mesh to 320 mesh to grind the surface of the steel plate, after the grinding is completed, the controller 9 controls the cleaning assembly 7 to clean the surface of the steel plate, and the back of the steel plate is polished through the conveying assembly, and after completion, the conveying assembly transports the steel plate away from the processing table 2.
