METHOD AND DEVICE FOR CORRECTING WIDTH WARP OF DEFORMED CROSS-SECTION BAR

摘要

PROBLEM TO BE SOLVED: To correct the warp of width. SOLUTION: The warp of width of a deformed cross-section bar I is corrected by pressing a die 2 having a circular cross-section shape onto the deformed shaped cross-section bar I which has a cross-section shape different in its thickness along the width direction and whose cross-section shape is formed continuously and uniformly in its longitudinal direction so that the circumferential direction (θdirection) is made along the longitudinal direction (X direction) of the deformed cross-section bar I and the radius direction (R direction) is directed toward the thickness (Y direction) of the deformed cross-section bar I, and bending the deformed cross-section bar I.
