METHOD FOR MANUFACTURING METAL COMPONENT WITH THREE-DIMENSIONAL EDGE AND DIE SETS FOR MANUFACTURING THE SAME

摘要

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.

1. A method for manufacturing a metal component with a three-dimensional edge from a blank as a raw material, the blank being cut from a metal sheet and having a curved edge portion with two ends, the method comprising:
providing at least one bend formation line in the curved edge portion so that a bend radius of a section of a bent portion bent downwardly or upwardly along a curve of the curved edge portion is in the range of 0.5 to 30 mm; and after providing the bend formation line, forming the three-dimensional shape by processing the curved edge portion, and optionally by also processing the part of the blank adjacent to the curved edge portion, into the three-dimensional shape from the bend formation line by moving both end portions of the curved edge portion so as to reduce or increase a distance between the two ends.
