Abstract
The invention discloses a pre-bending device of a cooling table. The pre-bending device comprises a plurality of parallel longitudinal beams and traveling mechanisms; a track and a driving device are arranged on each longitudinal beam, the traveling mechanisms travel on the tracks, and the driving devices are used for driving the traveling mechanisms to travel; and a first crossbeam and a second crossbeam which are used for supporting the longitudinal beams are symmetrically arranged on lower sides of the longitudinal beams, and a plurality of groups of linkage mechanisms are arranged below the first crossbeam and the second crossbeam. The pre-bending device is simple in structure and smart in design. During usage, the second crossbeam is pushed by hydraulic cylinders to ascend at first, section bars are clamped in bayonets, and then driving mechanisms drive trolleys to bend section steel towards a direction opposite to a cooling shrinkage direction of the section steel by a certain radian before the section steel is cooled, so that bending of the section steel can be reduced after the section bars are cooled, the section steel can be conveyed conveniently and can be straightened advantageously, the yield is increased, and the production efficiency is improved.
