Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to a straightening machine used for H-shaped steel. Background Art

[0002] H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structural weight. It has been widely used. When straightening, H-shaped steel needs to be shaped with the help of a straightening machine for regular processing.

[0003] The existing straightening machine for H-beam has only one set of horizontal straightening wheels. When performing the straightening work, it is necessary to manually flip the steel to correct the other side after the straightening is completed on one side, resulting in low work efficiency. For this reason, we provide a straightening machine for H-beam. Utility Model Content

[0004] The purpose of the utility model is to provide a straightening machine for H-shaped steel to solve the problem that the existing straightening machine for H-shaped steel proposed in the above background technology has only one set of transverse straightening wheels. When performing the straightening work, it is necessary to manually flip the steel after one side has been straightened to straighten the other side, resulting in low work efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a straightening machine for H-shaped steel, comprising a straightening platform, two machine bases are arranged at the upper end of the straightening platform, a vertical inner groove and two horizontal inner grooves are arranged inside the two machine bases, and a first hydraulic cylinder and a second hydraulic cylinder are arranged inside the vertical inner groove and the horizontal inner groove respectively;

[0006] Also includes:

[0007] A movable bracket, which is welded to one end of the piston rod of the first hydraulic cylinder, a driving motor is arranged inside the movable bracket, and a lateral correction wheel is arranged on one side of the movable bracket;

[0008] A load-bearing wheel seat, which is welded and arranged at one end of the piston rod of the second hydraulic cylinder, and one end of the load-bearing wheel seat is provided with two longitudinal correction wheels, a series connection shaft is arranged in series between the two longitudinal correction wheels, and the two longitudinal correction wheels and the series connection shaft are an integrated structure;

[0009] The center wheel groove is arranged at the center position of the correction platform, and a displacement guide wheel is arranged inside the center wheel groove.

[0010] Preferably, a micro motor is arranged in the internal cavity of the load-bearing wheel seat, a first sprocket is welded on the output shaft of the micro motor, and a second sprocket is welded on the series connection shaft.

[0011] Preferably, a transmission chain is sleeved between the first sprocket and the second sprocket, and the micro motor is transmission-connected to the series-connected shaft via the transmission chain.

[0012] Preferably, bearing connection holes are provided on the inner walls on both sides of the central wheel groove, and the rotating shaft at the center position of the displacement guide wheel is movably connected to the central wheel groove through the bearing connection holes.

[0013] Preferably, a transmission connecting shaft is provided on an inner wall of one side of the lateral correction wheel, the transmission connecting shaft and the lateral correction wheel are an integrated structure, and the driving motor and the transmission connecting shaft are located on the same horizontal line.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model adds two groups of longitudinal correction wheels. After the steel enters the working area, it does not need to be turned over manually. Instead, double-sided correction is achieved through the simultaneous action of the longitudinal and transverse correction wheels, thereby improving work efficiency and reducing labor costs. The H-shaped steel that needs to be corrected is corrected transversely and longitudinally by a group of transverse correction wheels and two groups of longitudinal correction wheels, thereby achieving double-sided correction. The first hydraulic cylinder drives the movable support to be raised and lowered, so that the height of the transverse correction wheel can meet the correction requirements of H-shaped steels of different thicknesses. The second hydraulic cylinder drives the load-bearing wheel seat to perform horizontal displacement activities, thereby allowing the two groups of longitudinal correction wheels to be adjusted accordingly to adapt to the correction of H-shaped steels of different thicknesses.

[0018] When the H-beam is being corrected on both sides, it is in contact with the displacement guide wheel, so that the corrected H-beam can slide and move, improving the smoothness of the double-sided correction operation. BRIEF DESCRIPTION OF THE DRAWINGS
