Abstract
PURPOSE: To sharply fold the sheet while conserving its beautiful appearance, and to improve the beauty of appearance of the folded product, by cutting a V-groove of prescribed angle and depth off in the inner side of the part to be folded in the sheet, and by folding the sheet.
CONSTITUTION: A 90° V-groove 2 is cut off in the inner side 1a of the part to be folded in a steel sheet 1 of thickness T. The V-groove 2 is cut to a depth (h) determined so as to leave in the sheet a thickness (t) equal to about 1W1/2 of radius R of the outside corner to be formed by the folding work, and then, the sheet 1 is folded. Or otherwise, the 90° V-groove 2 is cut off in the inner side 1a of the part to be folded in the sheet of thickness T to a depth (h) similar to above said depth (h). And additionally, at the apex of the V-groove 2, a round small groove having a radius (r) equal to about 1W1/2 of radius R of the outside corner is formed, V- groove 2 that the tangent to the round groove (r) is in contact with the inner side 1a of the part to be folded at 90° angle is cut off and then, the sheet 1 is folded.
