METHOD FOR PRODUCING STEEL SHEET FOR PRESS MOLDING, AND METHOD AND DEVICE FOR PRODUCING PRESS-MOLDED COMPONENT

摘要

[Problem] To provide a method for producing a non-rectangular steel sheet to be heated to the predetermined temperature, a method and apparatus for producing a press-molded article using the non-rectangular steel sheet for press molding that is produced by means of that method for producing the same.;[Solution] The method for producing a steel sheet for press molding according to one embodiment of the invention includes an electrical heating process (STEP-101) for electrically heating a blank (10) of rectangular steel sheet, viewed from the thickness direction of the blank, and a bending process (STEP-102) for deforming the blank (10) from a rectangle to a non-rectangle by applying stress in a horizontal direction to the surfaces (front (10a) and back (10b)) of the blank (10) after the start of electrical heating.
