Angle steel pre-straightening device

Abstract

The invention relates to hot-rolled angle steel production line before-shearing straightening equipment, belongs to the technical field of hot-rolled angle steel straightening equipment, and discloses an angle steel pre-straightening device. According to the technical scheme, the angle steel pre-straightening device comprises a power assembly (1), a coupling (2), a lower straightening roller set (3), a press-down adjusting mechanism (4), an upper straightening roller set (5), a roller frame (6) and a horizontal adjusting mechanism (7). The upper straightening roller set (5) and the lower straightening roller set (3) are arranged in the roller frame (6) and are arranged in an up-and-down parallel manner. The lower straightening roller set (3) is in drive connection with the power assembly (1) through the coupling (2). The upper straightening roller set (5) is provided with the press-down adjusting mechanism (4) and the horizontal adjusting mechanism (7). The angle steel pre-straightening device has the beneficial effects that the functions of online pre-straightening, angle steel dredging and conveying before angle steel shearing are achieved; the labor intensity of staff is reduced; angle steel is flatly and precisely conveyed onto a cold shear blade; and the angle steel quality accidents of angle steel shear deformation and the like caused by angle disorderliness and inclination are eradicated.

Description

technical field [0001] The invention relates to a pre-shear straightening equipment for a hot-rolled angle steel production line, and belongs to the technical field of hot-rolled angle steel straightening equipment. Background technique [0002] The hot-rolled angle steel is prone to bending, overturning and deformation after cooling in the cooling bed, so that the angle steel cannot pass through the cold shear smoothly, and it is prone to production failures and quality accidents such as the top shear edge of the angle steel, chaotic steel, and shear deformation of the angle steel. In order to meet the production demand, before the angle steel is cut, the angle steel needs to be manually smoothed and sent to the cold shear. The productivity of the rolling line is extremely low, and the labor intensity of the workers is too high, which is not conducive to the angle steel shearing and production, and affects the angle steel shearing. Quality, even leaving safety hazards, also...

[0002] The hot-rolled angle steel is prone to bending, overturning and deformation after cooling in the cooling bed, so that the angle steel cannot pass through the cold shear smoothly, and it is prone to production failures and quality accidents such as the top shear edge of the angle steel, chaotic steel, and shear deformation of the angle steel

In order to meet the production demand, before the angle steel is cut, the angle steel needs to be manually smoothed and sent to the cold shear. The productivity of the rolling line is extremely low, and the labor intensity of the workers is too high, which is not conducive to the angle steel shearing and production, and affects the angle steel shearing. Quality, even leaving safety hazards, also caused a waste of manpower and material resources
