Title:
METHOD FOR MANUFACTURING HOT-STAMP-MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2016/088665
Kind Code:
A1
Abstract:
A method for manufacturing a hot-stamp-molded article is provided with a heating step (E1) for heating a steel sheet blank (12), a pressing step (E2) for molding the heated blank (12) by hot-stamp molding into a high-strength pressed component (15) and left and right heat-distortion-suppressing sections (16, 17), and an annealing step (E3) for annealing left and right connection flanges (26, 27) in the pressed component (15). In the annealing step (E3), in a state in which heat deformation of the left connection flange (26) is suppressed by the left heat-distortion-suppressing section (16), the left connection flange (26) is annealed to form a left ductile section (41). In the same manner, in a state in which heat deformation of the right connection flange (27) is suppressed by the right heat-distortion-suppressing section (17), the right connection flange (27) is annealed to form a right ductile section (42).
