曲げ板金部品の製造のための方法及び装置
Document Type and Number:
Japanese Patent JP4102480
Kind Code:
B2
Abstract:
A method and apparatus for the production of bent sheet metal pieces (12) is disclosed. In the method or apparatus, a cut (14) is made in a sheet of sheet metal (10) that defines the perimeter of piece (12) to be obtained. The cut (14) is interrupted at preselected points to form a series of microjoints (16) that keep the plan development of the piece (12) united with the stiffening frame (18) constituted by the remaining part of the metal sheet (10). At least one window (36, 38) is formed in the stiffening frame (18) in order to allow a pair of bending tools having a length greater than the length of the bend to form a bend (20, 22) on the piece (12) without interfering the stiffening frame (18) while the bend is being formed.
