Embodiment Construction

[0022] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, exemplary embodiments of the present invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0023] Such as Figure 1 to Figure 5 Commonly shown, the large-thickness section steel straightening machine includes a machine base 1, on which at least two straightening seat installation rods 2 are installed, and on the said straightening seat installation rods 2 are commonly installed two oppositely arranged straightening seats 3 . One of the straightening seat mounting rods 2 is rotatably equipped with an initial ...

Abstract

The invention discloses a large-thickness profile steel straightening machine. The straightening machine comprises a machine base, wherein at least two straightening base mounting rods are mounted onthe machine base, two straightening bases are jointly mounted on the straightening base mounting rods, a primary straightening supporting roller is rotationally installed on one straightening base mounting rod, primary straightening pressing devices are arranged on the two straightening bases respectively, a re-straightening supporting shaft is rotationally installed on the machine base, a re-straightening supporting roller is fixedly installed on the re-straightening supporting shaft, a re-straightening feeding driver is arranged between the re-straightening supporting shaft and the machine base, the primary straightening supporting roller is connected with a primary straightening feeding driver, and a re-straightening pressing device is arranged on each straightening base. According to the straightening machine, acting force is transmitted without passing through the machine base, the bending moment effect borne by a structural part can be obviously reduced through the structural compactness, the strength of the structural part is amplified, meanwhile, influences caused by insufficient strength of some connecting structures are reduced, the force application effect is better, andlarge-thickness profile steel straightening can be achieved.

Description

technical field [0001] The invention relates to the technical field of section steel straightening equipment, in particular to a large thickness section steel straightening machine. Background technique [0002] The processing of H-shaped steel is mainly divided into two methods: assembly welding and hot rolling. Among them, the assembly welding method is widely used because of its flexible cross-section and thickness. Assembly welding is mainly to assemble and weld the two wing plates and the web plate, and the welding seam is heated intensively, and the wing plate will inevitably be bent and deformed. Therefore, in the production process of H-shaped steel welding, a correction process is usually required to correct the above-mentioned bending deformation. [0003] The vigorous development of the construction industry at this stage has put forward higher requirements for the structural strength of H-shaped steel, and the demand for large-thickness steel is increasing day b...
