AUTO COMPENSATION APPARATUS TO GET STRAIGHTNESS OF PIPE BENDING

摘要

PURPOSE: An apparatus for automatically compensating the bending straightness of a pipe is provided to prevent the deterioration of straightness of a long bent pipe which is formed by bending a plate. CONSTITUTION: An apparatus for automatically compensating the bending straightness of a pipe comprises a bed frame and lower and upper dies which are arranged on the bed frame. The lower die comprises a plurality of bending dies(210) on which a plate is placed and a compensating unit which is arranged under the bending dies and comprises a plurality of lifting plates. The lifting plates are lifted by a push plate moving horizontally and support the bending dies. The upper die is lowered by an actuator to press the plate.
