Description

Technical Field

[0001] The invention relates to the technical field of leveling machines, and in particular to a flat plate machine for leveling metal plates. Background Art

[0002] Leveling machine is a kind of equipment used to correct the flatness of metal sheets or profiles. It is mainly used to eliminate bending, warping or unevenness of materials during processing. It applies alternating bending force to the material through a series of leveling rollers or roller groups arranged in an up-and-down staggered manner, so that uniform plastic deformation occurs inside the material, thereby eliminating internal stress and achieving a flat effect.

[0003] A tie rod pressing and leveling machine is disclosed in the patent with patent publication number CN103846315A, including a tie rod, a movable upper beam, and a fixed lower beam. The movable upper beam is provided with an upper leveling roller, and the fixed lower beam is provided with a lower leveling roller. The four corners of the movable upper beam are connected to the tie rod, and the fixed lower beam is connected to a tie rod pressing power mechanism. The tie rod is arranged in tie rod seats at both ends of the upper beam, and a tie rod power device is provided at the bottom of the fixed lower beam corresponding to the tie rod seat. The tie rod is arranged in the tie rod seat and connected to the power device, and the power device causes the tie rod to move relative to the tie rod seat in the axial direction. The tie rod pressing and leveling machine with the above structure eliminates the transverse end beam and the longitudinal cross beam, making the machine body structure simpler. The fulcrum of the pressing power device is located at the outermost side of the movable upper beam, which is easy to control the balance of the leveling roller.

[0004] The prior art has the following defects:

[0005] When placing the sheet to be leveled in the leveler, it is very important to ensure that the sheet is as perpendicular to the rollers as possible. This is because the rollers of the leveler correct the shape of the sheet by applying alternating bending forces to the material. If the sheet is not aligned correctly, it may result in uneven leveling, damage to the equipment or reduced leveling accuracy. Therefore, in order to ensure the leveling effect and the normal operation of the equipment, it is usually necessary to ensure that the sheet is as perpendicular to the rollers of the leveler as possible through an alignment system or a guide device. Many existing levelers are designed so that the operator needs to make manual adjustments to accurately place the material. Summary of the invention

[0006] In view of the above problems in the prior art, a flat plate machine for correcting metal sheets is proposed.

[0007] The present application provides a flat plate machine for straightening metal plates, the purpose of which is to provide a device that can adjust the center of the plate to be straightened by relying on the plate's own gravity when placing the plate to be straightened, and automatically slide it into the straightening roller group after the adjustment is completed.

[0008] The technical solution of the present invention is: a flat plate machine for straightening metal plates, comprising a cabinet, a roller frame arranged on the cabinet, a pair of input rollers arranged on the roller frame, a plurality of pairs of leveling rollers and a pair of output rollers, characterized in that: the cabinet is provided with a plate straightening mechanism on one side of the input roller;

[0011] Furthermore, a limiting platform is provided on the upper end of the guide roller.

[0012] By adopting the above scheme, a limit table is provided to clamp the sheet to be pressed in the vertical direction.

[0013] Furthermore, the centering component includes a pair of slide rails, a pair of slide plates are slidably arranged on the slide rails, a through hole is opened at the center of the rotating plate, a rotating cylinder is arranged at the through hole, a straight rod 1 is symmetrically arranged on the upper end of the rotating cylinder, a straight rod 2 is hinged in the middle of each of the slide plates, and the straight rod 1 is hinged to the straight rod 2, a guide column is arranged on the bearing plate, the guide column extends into the rotating cylinder, a spiral groove is opened in the guide column, a cross bar is fixed in the rotating cylinder, and the cross bar passes through the spiral groove.

[0014] By adopting the above scheme, a centering component is set up. When the plate to be pressed is placed on the conveying roller, the weight of the plate causes the rotating plate to rotate relative to the supporting plate. At the same time, the cross bar moves downward and rotates in the spiral groove. The cross bar drives the rotating cylinder to rotate and pulls a pair of slides to move toward each other through straight rods one and two, so that the guide rollers on the pair of slides push the plate to be pressed to the middle position of the conveying roller.

[0015] Furthermore, a spring is arranged between the rotating plate and the bearing plate.

[0016] By adopting the above scheme, a spring is provided to reset the rotating plate and the guide roller after the sheet to be pressed is conveyed into the roller group for leveling.

[0017] Furthermore, a blocking rod is arranged on one side of the carrying plate close to the input roller, and a notch is arranged at the end of the blocking rod.

[0018] By adopting the above scheme, a blocking rod is set to block the plate to be pressed when it is just placed on the conveying roller. When the rotating plate rotates under the gravity of the plate to be pressed and the position of the plate to be pressed is centered by the guide roller, the rotating plate is located above the blocking rod, so that the plate to be pressed passes through the blocking rod and enters the roller group for leveling.

[0019] Furthermore, the upper and lower end surfaces of the rotating cylinder are respectively fixed with an upper table and a lower table, a cylinder sleeve is arranged above the through hole, the cylinder sleeve is sleeved on the outer wall of the rotating cylinder, the upper table and the upper end surface of the cylinder sleeve are in contact with each other, and the lower table and the bottom surface of the rotating plate are in contact with each other.

[0024] By adopting the above scheme, a vertical adjustment mechanism is provided to adjust the gap between the roller groups to adapt to the leveling of plates with different thicknesses.

[0025] Beneficial effects of the present invention:

[0026] 1. By setting up a plate adjustment mechanism, after the plate to be pressed is placed on the conveying roller, the guide rollers on both sides of the plate to be pressed move towards each other, positioning the plate to be pressed in the middle of the conveying roller, and then sliding into the roller group through the conveying roller for leveling.

[0027] 2. By setting a centering component, when the plate to be pressed is placed on the conveyor roller, the weight of the plate causes the rotating plate to rotate relative to the load-bearing plate, and at the same time the cross bar moves downward and rotates in the spiral groove. The cross bar drives the rotating cylinder to rotate and pulls a pair of slides to move toward each other through straight rods 1 and 2, so that the guide rollers on the pair of slides push the plate to be pressed to the middle position of the conveyor roller.

[0028] 3. By setting up a blocking rod, the plate to be pressed is blocked when it is just placed on the conveying roller. When the rotating plate rotates under the gravity of the plate to be pressed and the position of the plate to be pressed is centered through the guide roller, the rotating plate is located above the blocking rod, so that the plate to be pressed passes through the blocking rod and enters the roller group for leveling.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] Example 1, reference Figure 1-9, which is the first embodiment of the present invention, provides a flat plate machine for correcting metal sheets, including a cabinet 1, a roller frame 2 arranged on the cabinet 1, a pair of input rollers 3 arranged on the roller frame 2, multiple pairs of leveling rollers 4 and a pair of output rollers 5, the cabinet 1 is provided with a plate adjustment mechanism on one side of the input roller 3; the plate adjustment mechanism includes a load-bearing plate 6 arranged on the cabinet 1, a rotating plate 7 hinged to the load-bearing plate 6, multiple pairs of support frames 8 are arranged on both sides of the rotating plate 7, each pair of support frames 8 is rotatably provided with a conveying roller 9, a pair of slide plates 10 are arranged below the conveying roller 9, the slide plates 10 are perpendicular to the conveying roller 9, a plurality of rotating shafts 11 are vertically arranged on the slide plates 10, the plurality of rotating shafts 11 pass through the gaps between the plurality of conveying rollers 9 and extend to above the conveying rollers 9, guide rollers 12 are rotatably provided on the rotating shafts 11, and a pair of slide plates 10 are connected by a centering component. The leveling rollers 4 are divided into two rows, upper and lower, and are arranged in a staggered manner. The material is repeatedly bent between the upper and lower rollers. The upper and lower rollers rotate in opposite directions. In this way, the internal residual stress of the material is evenly released after multiple reverse bending, thereby achieving a leveling effect. The spacing between the rollers gradually decreases, with a larger spacing between the rollers at the entrance and a smaller spacing at the exit, which is used to gradually reduce the bending amplitude of the plate and achieve a leveling effect. The adjustment of the spacing between the rollers is related to the thickness of the plate: thin plates require a smaller spacing between the rollers, while thick plates require a larger spacing.

[0042] Specifically, the carrying plate 6 is fixed to one side of the input roller 3 of the cabinet 1 through the support frame 8. A pair of lower rotating frames are arranged on the upper surface of the carrying plate 6 near the input roller 3. Correspondingly, a pair of upper rotating frames are arranged on the lower surface of the rotating plate 7. The lower rotating frames and the upper rotating frames are hinged. The surfaces of the plurality of conveying rollers 9 are smooth, and the sliding resistance of the sheet to be pressed on the surfaces of the plurality of conveying rollers 9 is small. The plurality of conveying rollers 9 are arranged at equal intervals. The number of rotating shafts 11 on the single-sided slide 10 is the same as the number of gaps between the conveying rollers 9, and the number of guide rollers 12 is the same as the number of rotating shafts 11. Correspondingly, in the idle state, the rotating plate 7 is in an inclined state, and the height of the conveying roller 9 closest to the input roller 3 is lower than the leveling gap of the roller group. When the plate to be pressed is placed on multiple groups of conveying rollers 9, the rotating plate 7 rotates to a nearly horizontal state under the action of the gravity of the plate to be pressed. At a small inclination angle, the plate to be pressed slides along the conveying roller 9 and just enters the gap of the roller group for leveling. During the rotation of the rotating plate 7, the centering component is used to drive a pair of slides 10 to make them move relative to each other, so that the guide rollers 12 move toward each other, and the plate to be pressed is positioned in the middle position of the conveying rollers 9.

[0043] By setting up a plate adjustment mechanism, after the plate to be pressed is placed on the conveying roller 9, the guide rollers 12 on both sides of the plate to be pressed move toward each other, positioning the plate to be pressed in the middle of the conveying roller 9, and then sliding into the roller group through the conveying roller 9 for leveling.

[0044] Reference Figure 3 A limiting platform 13 is provided at the upper end of the guide roller 12 .

[0045] The limiting platform 13 is provided to clamp the plate to be pressed in the vertical direction.

[0046] Reference Figure 3-Figure 6 The centering component includes a pair of slide rails 14, a pair of slide plates 10 are slidably arranged on the slide rails 14, a through hole 15 is opened at the center of the rotating plate 7, a rotating cylinder 16 is arranged at the through hole 15, and a straight rod 17 is symmetrically arranged on the upper end of the rotating cylinder 16. A straight rod 2 18 is hinged in the middle of each slide plate 10, and the straight rod 17 is hinged to the straight rod 2 18. A guide column 19 is arranged on the bearing plate 6, and the guide column 19 extends into the rotating cylinder 16. A spiral groove 20 is opened in the guide column 19. A cross bar 21 is fixed in the rotating cylinder 16, and the cross bar 21 passes through the spiral groove 20.

[0047] Specifically, the slide rail 14 is parallel to the conveying roller 9, the rotating cylinder 16 is rotatably set in the through hole 15, the bottom of the guide column 19 is fixed on the supporting plate 6 and the guide column 19 is set along the movement direction of the rotating cylinder 16, the rotating cylinder 16 follows the movement arc of the rotating plate 7 within a short distance and is approximately regarded as a straight line, the shape of the spiral groove 20 in any horizontal cross-section is rectangular, when the cross bar 21 slides downward in the spiral groove 20, it will rotate at the same time, in addition, the guide column 19 is an elastic material, allowing the cross bar 21 to produce a certain inclination when moving in the spiral groove 20, during the rotation of the rotating cylinder 16, the angle between the straight rod 17 and the straight rod 2 18 gradually decreases, and the straight rod 2 18 pulls a pair of slide plates 10 to slide toward each other along the slide rail 14.

[0048] By setting a centering component, when the plate to be pressed is placed on the conveying roller 9, the weight of the plate causes the rotating plate 7 to rotate relative to the supporting plate 6, and at the same time the cross bar 21 moves downward and rotates in the spiral groove. The cross bar 21 drives the rotating cylinder 16 to rotate and pulls a pair of slides 10 to move toward each other through straight rod 17 and straight rod 2 18, so that the guide rollers 12 on the pair of slides 10 push the plate to be pressed to the middle position of the conveying roller 9.

[0049] Reference Figure 5 A spring 22 is arranged between the rotating plate 7 and the supporting plate 6, and the spring 22 is located on the side of the supporting plate 6 away from the input roller 3. The elastic force of the spring 22 should be slightly greater than the gravity of the rotating plate 7 under the empty turntable. After the sheet to be pressed is placed on the conveying roller 9, the spring 22 is compressed.

[0050] By providing the spring 22, the rotating plate 7 and the guide roller 12 are reset after the sheet to be pressed is conveyed into the roller group for leveling.

[0051] Reference Figure 7 A blocking rod 23 is provided on one side of the carrying plate 6 close to the input roller 3 , and a notch 24 is provided at the end of the blocking rod 23 .

[0052] Specifically, when the rotating plate 7 is tilted, the side of the notch 24 that is in contact with the plate to be pressed is perpendicular to the rotating plate 7, which can better block the plate to be pressed. Before the rotating plate 7 rotates to a nearly horizontal state, the blocking rod 23 always blocks the plate to be pressed.

[0053] By setting up the blocking rod 23, the plate to be pressed is blocked when it is just placed on the conveying roller 9. When the rotating plate 7 rotates under the gravity of the plate to be pressed and the position of the plate to be pressed is centered by the guide roller 12, the rotating plate 7 is located above the blocking rod 23, so that the plate to be pressed passes through the blocking rod 23 and enters the roller group for leveling.

[0054] Reference Figure 5 An upper table 25 and a lower table 26 are fixed to the upper and lower end surfaces of the rotating cylinder 16 respectively. A cylinder sleeve 27 is arranged above the through hole 15. The cylinder sleeve 27 is sleeved on the outer wall of the rotating cylinder 16. The upper table 25 and the upper end surface of the cylinder sleeve 27 are in contact with each other, and the lower table 26 and the bottom surface of the rotating plate 7 are in contact with each other.

[0055] By providing the upper table 25 and the lower table 26 , the rotating cylinder 16 is restricted to rotate in the through hole 15 .

[0056] Referring to the figure, a drive motor 28 and a gear box 29 are provided on the cabinet 1 . The drive motor 28 is connected to the gear box 29 via a belt, and the gear box 29 is connected to the input roller 3 , the output roller 5 and the leveling roller 4 via a telescopic universal joint 30 .

[0057] Specifically, the telescopic universal joint 30 allows the roller group to maintain the transmission effect when the position height changes.

[0058] By providing a driving motor 28 and a gear box 29, a rotational force is provided to the roller set.

[0059] Referring to the figure, the input roller 3, the output roller 5 and the leveling roller 4 located on the upper side are all connected with a vertical adjustment mechanism 31.

[0060] The vertical adjustment mechanism 31 is provided to adjust the gap between the rollers to adapt to the leveling of plates with different thicknesses.

[0061] Working principle of the present invention:

[0062] When in use, first adjust the gap between the rollers according to the thickness of the plate to be pressed, place the plate to be pressed on the conveying roller 9, and the plate to be pressed slides close to the input roller 3 and is blocked by the blocking rod 23. The weight of the plate causes the rotating plate 7 to rotate relative to the supporting plate 6 and squeeze the spring 22. At the same time, the cross bar 21 moves downward and rotates in the spiral groove. The cross bar 21 drives the rotating cylinder 16 to rotate and pulls a pair of slide plates 10 to move toward each other through the straight rod 17 and the straight rod 2 18, so that the guide rollers 12 on the pair of slide plates 10 push the plate to be pressed to the middle position of the conveying roller 9. After the rotating plate 7 rotates to a nearly horizontal state, the rotating plate 7 is rotated and placed above the blocking rod 23, so that the plate to be pressed slides into the roller group through the blocking rod 23 for leveling. After the plate to be pressed is conveyed to the roller group and leveled, under the action of the spring 22, the rotating plate 7 and the guide roller 12 are reset.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
