Description

Technical Field

[0001] This utility model relates to the technical field of straightening devices for H-beam processing, specifically a straightening device for H-beam processing. Background Technology

[0002] H-beams are an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. They are named for their cross-section, which resembles the letter "H". Because all parts of an H-beam are arranged at right angles, it has advantages such as strong bending resistance in all directions, simple construction, cost savings, and light structural weight. It has been widely used. Generally, in order to ensure the reuse of H-beams after bending deformation, it is necessary to straighten the bent H-beams. In the prior art, such as the authorized announcement number CN219211150U, this utility model discloses a straightening device for H-beam processing, which relates to the field of steel profile straightening technology. The straightening device for H-beam processing includes a guide frame, which is U-shaped. A pressing cylinder is fixed to the top of the guide frame by bolts. A pressing frame is connected to the push rod of the pressing cylinder. The bottom ends of the pressing frame are both annular and are sleeved on the guide shafts on both sides of the upper pressure roller. The two guide shafts are connected to the two ends of the upper pressure roller through connecting seats. A lower pressure roller is fixed to the inner side of the guide frame through connecting seats. In this utility model, when the pressing cylinder is activated, it pushes the pressing frame, thereby driving the upper pressure roller to move. The guide shaft plays a guiding role. When the upper pressure roller presses tightly against the upper surface of the H-beam, the pushing cylinder is activated, which drives the pushing plate to move, thereby driving the steel profile to continuously press and straighten. It can straighten steel profiles of different thicknesses and can press them more tightly, improving the flatness of the straightening effect. The aforementioned patent uses a structure with two separate upper and lower extrusion straightening rollers to push the steel profile from one side for extrusion straightening. When the steel profile moves and is extruded, it will only become more and more bent and is prone to deviation and tilting. The straightening is inconvenient and the accuracy is low. In addition, the pushing and conveying stroke is limited and the length is greater than the size of the straightening machine, so it cannot be completely straightened. Utility Model Content

It has a simple structure and reliable operation. When used to achieve reciprocating motion, a speed reduction device can be eliminated, and there is no transmission gap, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference between its two sides. The hydraulic cylinder basically consists of a cylinder barrel and cylinder head, a piston and piston rod, and a sealing device.) The device consists of a buffer device and an exhaust device (existing technology). The hydraulic rod end face of the hydraulic cylinder 5 is fixedly connected to the lower surface of the straightening machine base 1.

Air in the engine cylinder converts thermal energy into mechanical energy through expansion; gas in the compressor cylinder is compressed by the piston to increase pressure, existing technology) is provided at the inner end of the angle-shifting frame 6. The main structure of the extrusion straightening roller driven by the hydraulic cylinder can convey the steel profile through the main body of the supporting conveying roller, and then extrude and flatten it through the four sets of extrusion straightening rollers. The outer side is clamped by the positioning wheel structure, which can be conveyed close to both sides of the steel profile to avoid deviation and tilting, and improve accuracy. The angle-folding moving frame 6 is distributed on the outer surfaces of the left and right sides of the straightening machine base 1, and its extrusion positioning wheels 8 are distributed on the left and right sides of the straightening machine base 1.

The supporting conveying roller body 2 is evenly and densely distributed on the inner surface of the straightening machine base 1. The supporting conveying roller body 2 can automatically convey the steel section. The four sets of extrusion straightening roller bodies 4 are distributed on the inner surface of the U-shaped support base 3. The four sets of extrusion straightening roller bodies 4 can be used to press and support the steel section. In conjunction with the rotation of the supporting conveying roller body 2, the steel section can be straightened through extrusion conveying. The supporting conveying roller body 2 is existing technology (the drive mechanism of the supporting conveying roller body 2 is existing technology). Hydraulic cylinders 5 are distributed at both ends of the lower surface of the U-shaped support 3; hydraulic cylinders 5 are distributed on both sides, which can increase the pressure balance and stabilizing force when the U-shaped support 3 moves up and down in the air. The lower surface of the extrusion positioning wheel 8 is close to the upper surface of the support conveying roller body 2. When the H-beam is placed on the support conveying roller body 2 for conveying, the sides of the H-beam can be extruded from both sides by the extrusion positioning wheel 8. When the H-beam is conveyed and extruded, it can fit into the positioning support and avoid deviation and tilting during correction. The upper surface of the extrusion positioning wheel 8 is provided with a convex shaft 9, which is connected to the inner surface of the angle moving frame 6 through a bearing.

The cylinder 7 is fixedly connected to the outer surface of the corner of the outer end of the angle moving frame 6, and the end face of the push rod of the cylinder 7 is fixedly connected to the outer surface of the straightening machine base 1; the movement of the angle moving frame 6 can be controlled by the extension and retraction of the cylinder 7, which can drive the extrusion positioning wheel 8 to move, and can drive the extrusion to be positioned on the outer surface of the H-beam, which is convenient to control. The working principle of this device is as follows: During use, a supporting conveying roller body 2 is provided on the inner surface of the straightening machine base 1.
