Embodiment

[0047] Such as Figure 1 to Figure 6 As shown, the present embodiment has two first medial correcting devices 4 devices, four first driving devices 9; Third inner orthotic device 8, first outer orthotic device 6, second outer orthotic device 2, third outer orthotic device, fourth outer orthotic device 10, second drive device 5, third drive device 7, fourth drive device 1. The number of conveying rollers is one; the first workbench and the second workbench 11 are connected by two guide rods 12 and two screw rods 13 . The first driving device 9 and the second driving device 5 are hydraulic cylinders; the third driving device 7 and the fourth driving device are motors.

[0048] When correcting and shaping, the distance between the sliding seat 1 and the mounting seat is regulated by rotating the screw mandrel 13; the number of correcting rings 18 on the transmission shaft 19 is determined (for example three) according to the workpiece (special-shaped steel to be corrected) size....

Abstract

The invention belongs to the technical field of deep processing of steel, in particularly relates to a special-shaped steel low-temperature correcting device. The device comprises a first workbench, asecond workbench, first inner side correcting devices, a second inner side correcting device, a third inner side correcting device, a first outer side correcting device, a second outer side correcting device and a third outer side correcting device; the first outer side correcting device is used for correcting the outer surface of the upper side of the special-shaped steel; the second outer sidecorrecting device and the second inner side correcting device are used for correcting the left side surface of the special-shaped steel; and the first inner side correcting devices are used for correcting the inner surface of the upper side of the special-shaped steel, and the third outer side correcting device and the third inner side correcting device are used for correcting the right side surface of the special-shaped steel. According to the device, the occupied area is small, the installation is convenient and flexible, the special-shaped steel can be accurately corrected, secondary damageto the special-shaped steel is avoided, and the device has the characteristics of being high in correcting precision, high in working efficiency and free of the secondary damage.

Description

technical field [0001] The invention belongs to the technical field of deep processing of steel, in particular, the invention relates to a low-temperature straightening device for special-shaped steel. Background technique [0002] Special-shaped steel is a kind of steel, and special-shaped steel is an emerging steel in steel structure buildings. The shape of special-shaped steel is various, and the special-shaped steel that the present invention refers is bar shape, and its section is as follows: Figure 6 As shown, the special-shaped steel of the present invention has an upper outer surface, an upper inner surface, a left outer surface, a left inner surface, a right outer surface, and a right inner surface. The left bottom and the right bottom of the special-shaped steel have left curling and right curling respectively. The currently produced larger-sized special-shaped steel is prone to side bending during cooling. After cutting to length, the side bending caused by the ...
