Deformation rectification device for aluminum alloy section bar

A deformation rectification device for an aluminum alloy section bar comprises a calibration platform, a pushing mechanism and columns, wherein the pushing mechanism is fixedly arranged on the calibration platform, the columns are vertically arranged on the calibration platform and located on the pushing-out side of the pushing mechanism, and the columns are at least two in number and symmetrically arranged opposite to the pushing mechanism. According to the deformation rectification device for the aluminum alloy section bar, the pushing mechanism is used for pushing the deformation portion of the aluminum alloy section bar for a while until plastic deformation is caused, and then the radian measure and the parallelism of later aluminum alloy section bar can be rectified to enable the aluminum alloy section bar to meet standards and requirements of clients.
