Description

Technical Field

[0001] This utility model belongs to the field of steel straightening technology, and in particular relates to a steel plate straightening device. Background Technology

[0002] Structural steel sections, such as I-beams, H-beams, and channel steel, are indispensable structural materials in industrial and construction fields. During their production, transportation, or storage, they often undergo plastic deformation such as bending and twisting due to residual stress, external impacts, and other factors, commonly known as "warping" or "wavy bending." These deformations severely affect the dimensional accuracy, structural strength, and subsequent installation and use of the structural steel sections, and therefore must be corrected through straightening processes.

[0003] In existing technologies, the straightening of structural steel, especially when straightening plates (horizontal and vertical plates) in different directions, typically suffers from the following shortcomings: Limited functionality: Traditional straightening equipment can often only straighten plates in a single direction. For example, ordinary presses or roller straighteners are mainly suitable for leveling horizontal plates, but lack effective pressure mechanisms and straightening methods for the vertical plates of the web or flanges of structural steel.

[0004] Low automation and low efficiency: When multiple parts need to be straightened, it is often necessary to manually adjust the position and posture of the steel profiles repeatedly, or to use auxiliary equipment such as overhead cranes for hoisting and turning. This process is not only cumbersome and labor-intensive, but also has poor positioning accuracy and low straightening efficiency.

[0005] Straightening accuracy is difficult to guarantee: Due to the lack of an integrated clamping, flipping and multi-angle pressure head adjustment system, the positioning stability of the steel profile is insufficient during the straightening process, which can easily lead to inaccurate force application points, affect the straightening effect, and may even cause secondary damage.

[0006] Therefore, there is an urgent need for a specialized device that can integrate clamping, automatic flipping, and flexible adjustment of the straightening angle to achieve efficient and precise integrated straightening of horizontal and vertical steel profiles.

[0007] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0008] To address the aforementioned problems, the purpose of this invention is to provide a steel plate straightening device. Through cleverly designed adjustment components and pressure heads, combined with a reversible clamping arm, it perfectly solves the straightening challenges of horizontal and vertical steel plates. A single set of equipment can complete the straightening operations for plates in two different orientations, exhibiting high functional integration and avoiding the time and cost waste associated with equipment replacement.

[0009] To achieve the above objectives, this utility model proposes a steel plate straightening device. The straightening device includes a worktable, on which symmetrically distributed adjustment components are fixed, and pressure heads are fixed on the adjustment components.

[0010] The adjustment assembly includes a vertical bracket fixed to the workbench, a U-shaped connecting fork fixed above the vertical bracket, a first electric telescopic rod rotatably mounted on the U-shaped connecting fork, a connecting rod vertically fixed on the output shaft of the first electric telescopic rod, and a pressure head fixed on the connecting rod.

[0011] Furthermore, symmetrically distributed clamping arms are fixed on the worktable.

[0012] Furthermore, the pressure head includes a connecting plate on which multiple hydraulic cylinders are fixed, and the pressure head also includes a pressure plate fixed on the output shaft of the hydraulic cylinders.

[0013] Furthermore, the clamping arm includes a vertical second electric telescopic rod, a connecting block is fixed on the output shaft of the second electric telescopic rod, a cylinder is fixed on one side of the connecting block, a drive box is fixed on the output shaft of the cylinder, a second motor is fixed inside the drive box, and a clamping plate is fixed on the side plate of the drive box away from the cylinder.

[0014] Furthermore, the second electric telescopic rod is fixed to the workbench.

[0015] Furthermore, the two clamps correspond to each other.

[0016] Furthermore, a first motor for driving the first electric telescopic rod to rotate is fixed on one side of the U-shaped connecting fork.

A single set of equipment can complete the straightening of plates in two different orientations, exhibiting high functional integration and avoiding the time and cost waste caused by equipment replacement.

[0019] 2. The straightening device of this utility model automatically completes the entire straightening process, including clamping, lifting, flipping, and lowering of the steel profile, as well as adjusting the angle, height, and position of the pressure head, through driving components such as electric telescopic rods, motors, and cylinders. Operators only need to issue commands through the control system to achieve fully automated operation, greatly reducing manual intervention, lowering labor intensity, and multiplying straightening efficiency.

[0020] 3. The straightening device of this utility model uses symmetrically distributed clamping arms to firmly clamp the steel from both ends, providing a stable force base for straightening and effectively preventing the steel from moving or shifting during the straightening process.

[0021] 4. The first motor and the first electric telescopic rod in the straightening device adjustment assembly of this utility model can drive the pressure head to perform precise rotation and telescopic movements, ensuring that the pressure plate can be quickly and accurately positioned directly above or opposite the plate to be straightened, and the force application point is precise.

[0022] 5. The straightening device of this utility model can finely adjust the horizontal position of the steel section by controlling the cylinders in the two clamping arms to extend one and shorten the other, so that the pressure head can cover all the parts of the plate that need to be straightened, ensuring that there are no dead angles in the straightening.

[0023] 6. The components of this utility model straightening device are scientifically arranged, the adjustment components are symmetrically distributed, the force is balanced, the pressure head adopts a multi-hydraulic cylinder driven pressure plate structure to ensure the uniformity of force application, and the clamping arm integrates lifting, translation and rotation functions, which can adapt to steel profiles of different sizes and specifications, and has strong versatility.

[0033] An embodiment of this utility model proposes a steel plate straightening device. The straightening device includes a workbench 1, as shown in the figure. A symmetrically distributed adjustment component 2 is fixed on the workbench 1, a pressure head 3 is fixed on the adjustment component 2, and a symmetrically distributed clamping arm 4 is fixed on the workbench 1.

[0034] Adjustment component 2 includes a vertical support 21 fixed on the worktable 1, such as... Figure 2 As shown, a U-shaped connecting fork 22 is fixed above the vertical support 21. A first electric telescopic rod 23 is rotatably mounted on the U-shaped connecting fork 22. A first motor 24 for driving the first electric telescopic rod 23 to rotate is fixed on one side of the U-shaped connecting fork 22. A connecting rod 25 is vertically fixed on the output shaft of the first electric telescopic rod 23. The pressure head 3 is fixed on the connecting rod 25.

[0035] The pressure head 3 includes a connecting plate 31, on which multiple hydraulic cylinders 33 are fixed. The pressure head 3 also includes a pressure plate 32, which is fixed on the output shaft of the hydraulic cylinders 33.

[0036] The clamping arm 4 includes a vertical second electrically operated telescopic rod 41, such as Figure 3 As shown, the second electric telescopic rod 41 is fixed on the workbench 1. A connecting block 42 is fixed on the output shaft of the second electric telescopic rod 41. A cylinder 43 is fixed on one side of the connecting block 42. A drive box 44 is fixed on the output shaft of the cylinder 43. A second motor 45 is fixed inside the drive box 44. A clamping plate 46 is fixed on the side plate of the drive box 44 away from the cylinder 43. The two clamping plates 46 are opposite each other. A buffer layer is provided on the clamping side of the clamping plate 46. The buffer layer is preferably made of rubber.

[0037] Working principle: Place the steel section to be straightened, with the two clamping arms 4 positioned at both ends of the steel section and the two adjusting components 2 positioned on both sides of the steel section.

[0038] Clamping: Activate the two second electric telescopic rods 41 to raise and lower them synchronously, driving the entire clamping arm 4 to adjust to a height that is compatible with the thickness of the steel profile. Then, the cylinder 43 is activated, pushing the drive box 44, the second motor 45 and the clamping plate 46 to move horizontally towards the steel profile until the two clamping plates 46 firmly clamp the steel profile from both ends. This clamping action provides a stable foundation for the subsequent straightening operation and prevents the steel profile from moving when under force.

[0039] When it is necessary to straighten the horizontal plate on the steel profile (here, the horizontal plate refers to a plate that can be laid flat on a horizontal surface), the clamping arm 4 is raised by starting the second electric telescopic rod 41, and then the steel profile is rotated by starting the second motor 45 so that the horizontal plate to be straightened faces downward. Then, the clamping arm 4 is lowered by starting the second electric telescopic rod 41 so that the steel profile is placed on the workbench 1. The pressure plate 32 is adjusted to face downward by starting the first motor 24. At this time, the first electric telescopic rod 23 is in a horizontal state. The pressure plate 32 is adjusted to be above the plate to be straightened by starting the first electric telescopic rod 23. The pressure plate 32 is moved downward by starting the hydraulic cylinder 33 to press and straighten the plate. After pressing, the pressure plate 32 is raised. One cylinder 43 is extended and the other cylinder 43 is shortened to adjust the position of the plate. After adjusting the position of the pressure plate 32 by starting the first electric telescopic rod 23, the pressure plate 32 is pressed on the plate until all the positions of the plate to be straightened are pressed.

[0040] When it is necessary to straighten the vertical plates on the steel profile (here, vertical plates refer to plates perpendicular to the horizontal plates), the first motor 24 is started to adjust the pressure plate 32 to be vertical and facing the vertical plate. At this time, the first electric telescopic rod 23 is in a vertical state. The height of the pressure plate 32 is adjusted by the first electric telescopic rod 23 to align it with the position to be straightened. The hydraulic cylinder 33 is started to control the two pressure plates 32 to move towards the vertical plate simultaneously until the vertical plate is pressed, thus straightening the vertical plate. The position of the plate is adjusted by controlling one cylinder 43 to extend and the other cylinder 43 to shorten. After adjusting the position of the pressure plate 32 by starting the first electric telescopic rod 23, the pressure plate 32 is controlled to press the plate until all positions of the plate to be straightened are pressed.
