摘要： PROBLEM TO BE SOLVED: To provide a method for stretch-forming a metal sheet, which, when stretch-forming a metal sheet to be stretch-formed by pushing a punch into the metal sheet, improves formability by setting up the timing, at which a punch or a die is once separated from the metal sheet, for the effective time.
SOLUTION: When stretch-forming a metal sheet to be stretched, which is fixed with a die and a blank holder, by pushing a punch into the metal sheet, a preliminary stretch-forming is beforehand carried out until a crack is generated on the preliminarily stretched product, and the distance from the position, at which the crack is generated, to the top position of stretching is measured. The preliminary stretch-forming is carried out while making such conditions as the material qualities and shapes of the die and the punch, the material quality and shape of the metal sheet to be stretched, blank-holding force, lubrication conditions, and stretch-forming speed, to be the same as those of actual stretching conditions. When actually stretching a metal sheet to be stretched, a step of once separating a punch or a die from the metal sheet is set behind the time when the metal sheet is stretched to the height corresponding to the above distance from the crack-generated position to the top position of stretching.
