Abstract
A method and die set for manufacturing a metal component with a three-dimensional edge from a blank as a raw material. The blank is cut from a metal sheet and has a curve-shaped curved edge portion with two ends. The method includes providing a bend formation line and forming the three-dimensional shape using a first die and a second die.
Claims3
A die set for manufacturing a metal component with a three-dimensional shape from a blank, the die set comprising:
- a first die having a surface profile including a downward or upward curve having a curve radius in a range of 0.5 to 30 mm that forms at least one bend formation;
- and
- a second die having:
- hold units configured to hold respective end portions of a curved edge of a blank,
- a holder holding one hold unit, and
- a cam slider holding another hold unit, the cam slider configured to slide against the holder in the horizontal direction,
- wherein the cam slider is configured to form the curved edge portion and a portion of the blank adjacent to the curved edge portion into the three-dimensional shape using the at least one bend formation by approaching or going away against the holder.
