  • Process for bending metal sheet
    Patent number: 4061098
    Abstract: A process for bending on a press a metal sheet through a desired angle and an inner bend radius less than the thickness of the sheet, without causing damages such as cracking in a bend. According to this process, a metal sheet is first bent through an angle approximating a desired angle, with an inner bend radius being greater than the thickness of the metal sheet, and then the metal sheet thus bent is further bent through a desired angle, with the inner bend radius being less than the thickness of the metal sheet, and with the stretching of a material of the metal sheet on the outer side of the bend being suppressed.
