[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figures 1-7 , a metal sheet correction device shown in the figure, comprising: a first load-bearing frame 1 and a second load-bearing frame 2 that bear the metal sheet. The first load-bearing frame 1 and the second load-bearing frame 2 are meshed and assembled. The first load-bearing frame 1 and the second load-bearing frame 2 are assembled in a staggered manner like comb teeth, and the upper end faces of the first load-bearing frame 1 and the second load-bearing frame 2 are on the same horizontal plane. An extrusion unit is provided at the top of the first load-bearing frame 1. The extrusion unit extrudes the metal sheet onto the upper end faces of the first load-bearing frame 1 and the second load-bearing frame 2 from top to bottom; It further includes: a heating component, and the heating component heats up the metal sheet through the first load-bearing frame 1 and the second load-bearing frame 2.

[0020] The extrusion unit includes a hydraulic cylinder body 7 located at the tops of the first load-bearing frame 1 and the second load-bearing frame 2. A support frame 8 is fixedly provided between the hydraulic cylinder body 7 and the first load-bearing frame 1. The output end of the hydraulic cylinder body 7 faces downward. The output end of the hydraulic cylinder body 7 is provided with a flattening plate 6 through a connecting member. The metal sheet is located between the flattening plate 6 and the first load-bearing frame 1 and the second load-bearing frame 2. The output end of the hydraulic cylinder body 7 can drive the flattening plate 6 to move up and down reciprocally through the connecting member, and during the downward movement, the bent metal sheet can be extruded and corrected through the flattening plate 6.

[0021] The heating component includes a second resistance heating tube 4 fixedly embedded at one end of the second load-bearing frame 2. A first resistance heating tube 3 is also fixedly embedded at the end of the first load-bearing frame 1 far from the second resistance heating tube 4. Both the first load-bearing frame 1 and the second load-bearing frame 2 are made of metal material. When the first resistance heating tube 3 and the second resistance heating tube 4 are powered on, heat can be generated and transferred to the first load-bearing frame 1 and the second load-bearing frame 2, so that the first load-bearing frame 1 and the second load-bearing frame 2 are heated up.

[0022] The connecting member includes a first sleeve column 11 fixed to the output end of the hydraulic cylinder body 7. An axially movable second sleeve column 12 is arranged inside the first sleeve column 11. The end of the second sleeve column 12 far from the hydraulic cylinder body 7 is fixed to the flattening plate 6. A spring 13 is placed inside the second sleeve column 12, and both ends of the spring 13 are fixed to the first sleeve column 11 and the second sleeve column 12 respectively. The second sleeve column 12 can only move up and down inside the first sleeve column 11 and cannot rotate.

[0023] Two symmetrically distributed edge protection strips 5 are also fixedly provided at the top of the first load-bearing frame 1. The edge protection strips 5 are parallel to the first load-bearing frame 1. The edge protection strips 5 are distributed on the front and back sides of the first load-bearing frame 1, mainly to prevent the metal sheet from falling from the front and back sides of the first load-bearing frame 1 during the movement.

[0024] The flattening plate 6 is located between the two edge protection strips 5, that is, when the flattening plate 6 extrudes the metal sheet, the edge protection strips 5 will not obstruct the flattening plate 6.

[0025] Embodiment 2: Please refer to Figure 6 and Figure 7 , this embodiment is a further description of Embodiment 1. The moving unit is used to move the leveled metal sheet, and the moving unit is arranged between the first load-bearing frame 1 and the second load-bearing frame 2; The moving unit includes a base plate 9 located below the first load-bearing frame 1 and the second load-bearing frame 2. Four vertical plates 10 distributed in a matrix are fixedly arranged between the base plate 9 and the first load-bearing frame 1. A connecting plate 26 is fixedly arranged at the bottom of the second load-bearing frame 2, and a second rotating shaft 24 is rotatably mounted at the bottom of the connecting plate 26. Two symmetrically distributed lifting frames 15 are fixedly arranged on the outer wall of the first load-bearing frame 1, and a first rotating shaft 16 is rotatably arranged inside each lifting frame 15. A crank block 25 is fixedly arranged between the two ends of the second rotating shaft 24 and the two first rotating shafts 16 respectively, and a rotating component is further arranged at the other end of the first rotating shaft 16. A limiting component is arranged between the bottom of the connecting plate 26 and the base plate 9. Due to the action of the rotating component and the limiting component, when the first rotating shaft 16 rotates, the connecting plate 26 can be restricted from swinging and moving due to the action of the limiting component. Therefore, the rotation of the first rotating shaft 16 can make the connecting plate 26 drive the second load-bearing frame 2 to make a clockwise circular motion, thereby lifting and then releasing the metal sheet, so that the position of the metal sheet is displaced.

[0026] The rotating component includes a movable ratchet gear 17 fixed to the end of the first rotating shaft 16 away from the second rotating shaft 24. A vertically arranged column 18 is arranged outside each movable ratchet gear 17, and a number of ratchet teeth blocks 19 are fixedly arranged at the end of the column 18 close to the movable ratchet gear 17. The ratchet teeth blocks 19 are movably meshed with the movable ratchet gear 17. An empty groove part 20 is formed at the top of the topmost ratchet teeth block 19 corresponding to the inside of the column 18. A smooth shaft 21 is further fixedly arranged at the top of the column 18, and an assembly rod 14 is fixedly arranged between the first sleeve column 11 and the two smooth shafts 21. A limiting sleeve block 22 is slidably sleeved outside each smooth shaft 21, and the limiting sleeve block 22 is fixed to the first load-bearing frame 1. When the column 18 moves downward, the ratchet teeth block 19 will not be meshed with the movable ratchet gear 17, allowing the movable ratchet gear 17 to rotate; when the column 18 moves upward and resets, the ratchet teeth block 19 can be meshed with the movable ratchet gear 17 and make the movable ratchet gear 17 rotate clockwise.

[0027] The limiting component includes two symmetrically distributed slide rail frames 23 fixed on the upper end surface of the base plate 9. The slide rail frames 23 are parallel to the first load-bearing frame 1 and the second load-bearing frame 2. Two sliding blocks 29 are slidably assembled inside each slide rail frame 23. A sliding sleeve 27 is fixedly arranged on the top of each sliding block 29. A sliding column 28 is slidably fitted inside the sliding sleeve 27, and the top of the sliding column 28 is fixed to the connecting plate 26. Through the restriction of the sliding block 29 by the slide rail frame 23 and the restriction of the sliding column 28 by the sliding sleeve 27, the connecting plate 26 can only move in a horizontal state and cannot tilt.

[0028] A limiting shaft 30 is also fixedly arranged inside each slide rail frame 23. The limiting shaft 30 slidably penetrates through the sliding block 29. The function of the limiting shaft 30 can enhance the stability of the sliding block 29 sliding inside the slide rail frame 23.

[0029] Working principle: Refer to Figure 1 , the staff places the metal sheet to be leveled and corrected between the leveling plate 6, the first load-bearing frame 1 and the second load-bearing frame 2, and inserts it from the left end. Before insertion, the first load-bearing frame 1 and the second load-bearing frame 2 need to be preheated in advance so that the temperatures of the first load-bearing frame 1 and the second load-bearing frame 2 can reach the temperature for eliminating the internal stress of the metal sheet. The thickness of the metal sheet to be leveled and corrected does not exceed 3 mm. Moreover, except for the hydraulic cylinder body 7, all other structures of the entire correction device are assembled inside a box body, and both ends of the box body have openings for the feeding and discharging of the metal sheet; When the hydraulic cylinder body 7 drives the leveling plate 6 to move downward through the output end, the metal sheet can be squeezed by the leveling plate 6 against the upper end surfaces of the first load-bearing frame 1 and the second load-bearing frame 2 for leveling and correcting the metal sheet. When the column 18 moves downward along with the output end of the hydraulic cylinder body 7, the ratchet block 19 will not touch the movable ratchet gear 17. When the output end of the hydraulic cylinder body 7 returns upward, the upward movement of the column 18 can cause the movable ratchet gear 17 to rotate through the meshing of the ratchet block 19, and the movable ratchet gear 17 rotates clockwise for one circle. Refer to Figure 6 , when the movable ratchet gear 17 drives the first rotating shaft 16 to rotate clockwise, under the restriction of the limiting component, the connecting plate 26 will perform a circular motion in a horizontal state once, thereby lifting and then releasing the metal sheet, and the metal sheet can be moved a certain distance towards the right end of the first load-bearing frame 1 and the second load-bearing frame 2. In this way, when the leveling plate 6 reciprocates up and down to level and correct the metal sheet, the metal sheet can be transferred a certain distance towards the right end of the first load-bearing frame 1 and the second load-bearing frame 2, enabling the corrected metal sheet to automatically leave the first load-bearing frame 1 and the second load-bearing frame 2 and realizing the function of automatic blanking.

[0030] Moreover, in this solution, by heating the metal sheet, the internal stress during the shaping and straightening process of the metal sheet can be eliminated, thus avoiding the situation that the metal sheet will still be slightly bent due to the action of stress after being extruded and flattened.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
