Abstract
A curved-part forming method for obtaining a curved part by performing forming on a blank formed of a single metal plate, the method including a bending process in which the blank having a curved outline corresponding to a curve of the curved part in a longitudinal direction is bent into a sectional shape corresponding to a division portion of a sectional shape of the curved part; and a joining process in which two or more portions obtained by the bending process are joined together.
Claims
exact text as granted — not AI-modified1 . A curved-part forming method for obtaining a curved part by performing forming on a blank formed of a single metal plate, the method comprising:
a bending process in which the blank having a curved outline corresponding to a curve of the curved part in a longitudinal direction is bent into a sectional shape corresponding to a division portion of a sectional shape of the curved part; and a joining process in which two or more portions obtained by the bending process are joined together.
2 . The method according to claim 1 , wherein, prior to the bending process, a folding line is formed in the blank or a cut is further formed in the blank.
3 . A curved part manufactured according to the method of claim 1 .
4 . A curved part manufactured according to the method of claim 2 .Join the waitlist — get patent alerts
