Description

Technical Field

[0001] This invention belongs to the field of steel plate straightening technology, specifically referring to a straightening device for straightening steel plates. Background Technology

[0002] Steel plates often exhibit defects such as waviness and warping after rolling and heat treatment, requiring straightening. Existing tension straighteners exert enormous tension and are prone to springback; roller straighteners are difficult to adjust parameters and are prone to torsional deformation; tension bending straighteners rely on large-volume tension roller sets and complex electronic control servo systems, resulting in high equipment costs and difficulty in flexibly straightening individual steel plates. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a straightening device for straightening steel plates. Through the layout design of the central roller and the side rollers, longitudinal pressure can be applied to the steel plate, so that the steel plate achieves its own straightening through reciprocating rolling contact with the central roller and the side rollers.

[0004] A single power source drives a dual adjustable crank mechanism, completely eliminating multi-axis servo control and achieving forced synchronization of tension and bending without the risk of losing synchronization, thus improving system robustness. The tension-bending coupling waveform can be changed by mechanically adjusting the eccentricity and phase difference, adapting to steel plates of different materials and thicknesses without the need to change tooling or modify the program, making it a multi-purpose machine.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a straightening device for straightening steel plates, including a reciprocating straightening component, a straightening adjustment component, a moving clamping component, a reciprocating transmission component, a drive device and a base. The reciprocating straightening component is provided in two sets. The reciprocating straightening component is disposed on the straightening adjustment component, the straightening adjustment component is disposed on the base, and the moving clamping component is disposed in the base. Preferably, the driving device is located on the base, and the reciprocating transmission assembly is located between the moving clamping assembly and the base.

[0006] Furthermore, the reciprocating straightening assembly includes a roller support, a central roller, and side rollers. The roller support is mounted on the straightening adjustment assembly. The central roller and side rollers are rotatably mounted in the roller support. There are two central rollers, one of which is located directly above the other. The side rollers are located on both sides of the central roller and do not overlap in the vertical direction.

[0007] Furthermore, the straightening adjustment assembly includes an upper support, a roller gap adjuster, and a mounting plate. The upper support is mounted on the base, and there are two sets of roller gap adjusters, which are respectively mounted on the upper support and the base. The mounting plate is located at the end of the roller gap adjuster, and the roller support is mounted on the mounting plate.

[0008] Furthermore, the movable clamping assembly includes a clamp and a guide rail. The guide rail is fixed to the inner wall of the base, and the clamp has sliders at both ends, which are engaged and slidably disposed in the guide rail.

[0009] Preferably, the movable clamping assembly further includes a steel plate, which is detachably disposed in the clamp.

[0010] Furthermore, the reciprocating transmission assembly includes a rotating connecting rod, a reciprocating seat, and a swing connecting rod. The reciprocating seat is located on the side of the clamp, and the two ends of the swing connecting rod are respectively hinged to the rotating connecting rod and the reciprocating seat.

[0011] Preferably, the two ends of the rotating connecting rod are respectively provided with mounting rings and hinge posts, the two ends of the reciprocating seat are symmetrically provided with cantilever rods, and the two ends of the swing connecting rod are respectively hinged to the hinge posts and cantilever rods.

[0012] Furthermore, the driving device includes a drive motor and a motor mount, the motor mount being disposed on a base, and the drive motor being disposed on the motor mount.

[0013] Preferably, the drive motor has symmetrically arranged output shafts, and the mounting ring is rotatably mounted on the output shafts.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: (1) A single power source drives a dual adjustable crank mechanism, completely eliminating multi-axis servo control, achieving forced synchronization of tension and bending, eliminating the risk of step loss, and improving the robustness of the system.

[0015] (2) By mechanically adjusting the eccentricity and phase difference, the bending coupling waveform can be changed, adapting to steel plates of different materials and thicknesses. No tooling or program modification is required, making it a multi-purpose machine.

[0016] (3) The tension roller group is eliminated, and the tension is generated directly by the moving clamp and the bending is superimposed, which greatly reduces the size, weight and manufacturing cost of the equipment.

[0017] (4) Elastic buffer avoids impact overload, bending roller rotates to protect the plate surface, tension and bending composite stress eliminates internal stress more thoroughly, plate shape is stable and does not rebound.

[0018] (5) Through the layout design of the center roller and the side roller, longitudinal pressure can be applied to the steel plate, so that the steel plate can achieve its own straightening in the reciprocating rolling contact with the center roller and the side roller.

[0024] like Figures 1-8 As shown, the present invention proposes a straightening device for straightening steel plate 32, including a reciprocating straightening assembly 1, a straightening adjustment assembly 2, a moving clamping assembly 3, a reciprocating transmission assembly 4, a driving device 5, and a base 6. The reciprocating straightening assembly 1 is provided in two sets, the reciprocating straightening assembly 1 is provided on the straightening adjustment assembly 2, the straightening adjustment assembly 2 is provided on the base 6, and the moving clamping assembly 3 is provided in the base 6. The drive unit 5 is located on the base 6, and the reciprocating transmission assembly 4 is located between the moving clamping assembly 3 and the base 6.

[0025] The reciprocating straightening assembly 1 includes a roller support 11, a central roller 12, and side rollers 13. The roller support 11 is mounted on the straightening adjustment assembly 2. The central roller 12 and the side rollers 13 are rotatably mounted in the roller support 11. There are two central rollers 12, with one of the central rollers 12 located directly above the other. The side rollers 13 are located on both sides of the central roller 12 and do not overlap in the vertical direction.

[0026] The layout design of the center roller 12 and the side roller 13 allows longitudinal pressure to be applied to the steel plate 32, enabling the steel plate 32 to straighten itself through reciprocating rolling contact with the center roller 12 and the side roller 13.

[0027] The straightening adjustment assembly 2 includes an upper support 21, a roller gap adjuster 22, and a mounting plate 23. The upper support 21 is mounted on the base 6. There are two sets of roller gap adjusters 22, which are respectively mounted on the upper support 21 and the base 6. The mounting plate 23 is located at the end of the roller gap adjuster 22, and the roller support 11 is mounted on the mounting plate 23.

[0028] The movable clamping assembly 3 includes a clamp 31 and a guide rail 33. The guide rail 33 is fixed to the inner wall of the base 6. The clamp 31 has sliders 311 at both ends, and the sliders 311 are engaged and slidably disposed in the guide rail 33.

[0029] The movable clamping assembly 3 also includes a steel plate 32, which is detachably disposed in the clamp 31.

[0030] The reciprocating transmission assembly 4 includes a rotating connecting rod 41, a reciprocating seat 42, and a swing connecting rod 43. The reciprocating seat 42 is located on the side of the clamp 31, and the two ends of the swing connecting rod 43 are hinged to the rotating connecting rod 41 and the reciprocating seat 42, respectively.

[0031] The rotating connecting rod 41 has a mounting ring 411 and a hinge post 412 at both ends, and the reciprocating seat 42 has cantilever rods 421 symmetrically arranged at both ends. The two ends of the swing connecting rod 43 are hinged to the hinge post 412 and the cantilever rod 421 respectively.

[0032] The drive device 5 includes a drive motor 51 and a motor base 52. The motor base 52 is mounted on the base 6, and the drive motor 51 is mounted on the motor base 52.

[0033] The drive motor 51 has symmetrically arranged output shafts 511, and the mounting ring 411 is rotatably mounted on the output shafts 511.

[0034] In practical use, the user first needs to pass the steel plate 32 through the gap between the center roller 12 and the side roller 13, and install the end on the clamp 31. Then, according to the thickness specification of the steel plate 32, the user adjusts the distance between the two mounting plates 23 through the roller gap adjuster 22, thereby adjusting the longitudinal distance between the center roller 12 and the side roller 13.

[0035] After adjustment, start the drive motor 51. The output shaft 511 drives the rotating connecting rod 41 to rotate, and drives the reciprocating seat 42 through the swing connecting rod 43, thereby driving the clamp 31 to slide back and forth along the guide rail 33.

[0036] As the guide slide rail 33 slides back and forth, it drives the steel plate 32 to slide back and forth. During this process, the center roller 12 and the side roller 13 rotate passively to achieve the roll straightening of the steel plate 32. When the clamp 31 pushes the steel plate 32, the longitudinal squeezing of the side roller 13 and the center roller 12 is mainly used to achieve reverse bending and straightening of the steel plate 32. When the clamp 31 pulls the steel plate 32, in addition to bending and straightening in the opposite direction, the flatness of the steel plate 32 can be further improved by using the pulling force.

[0037] The distance between the two mounting plates 23 can be adjusted by the roller gap adjuster 22, thereby matching steel plates 32 of different thicknesses and different straightening stages of steel plates 32 of the same thickness.
