The invention discloses a method of using a die correction mechanism to correct bending deformation of punched products. The method is mainly characterized by including: mounting a striping correctioninsert with multiple inwards-concave correction tooth grooves distributed along the longitudinal direction of a die at intervals onto a striping backboard of the die in a state that the correction tooth grooves are downward; mounting a lower die correction insert with correction convex teeth matched with the correction tooth grooves onto a lower die backboard of the die in a state that the correction convex teeth are upward; driving an upper die seat through a punching machine to drive the striping backboard to link the striping correction insert to move up and down to enable the striping correction insert and the lower die correction insert to be in up-down meshing to correct bending deformation of a product material belt in the process of die punch forming. By the method, in the processof punch forming, a vertically-downward IC chip metal frame with arc-shaped bending deformation can be effectively corrected, so that quality requirements can be improved substantially to increase production yield so as to meet increasingly tense needs, and promoting of further development of information technology is facilitated.
