Abstract
The disclosure relates to a method for producing a shaped sheet metal part from a billet by UO forming. First, a preform is created by the U-forming. Then, final forming to give a final form is carried out by the O-forming. The preform has in cross section a maximum width that is smaller than the maximum width of the final form produced after the O-forming.
Claims14
A method of producing a shaped sheet metal part from a billet by UO forming, said method comprising:
- creating a preform from the billet by U-forming;
- then
- performing intermediate forming, wherein the intermediate forming comprises at least one of
- curling the preform, or
- upsetting the preform in a cross section so as to increase a wall thickness of the preform in the cross section;
- and then
- performing final forming to shape the preform into the shaped sheet metal part by O-forming,
- wherein the preform has, in the cross section, a maximum width that is smaller than a maximum width of a cross section of the shaped sheet metal part produced after the O-forming.
A method of producing a shaped sheet metal part from a billet by UO forming, said method comprising:
- creating a preform from the billet by U-forming;
- then
- curling the preform;
- and then
- performing final forming to shape the preform into the shaped sheet metal part by O-forming, and
- wherein during the curling, a maximum width of a cross section of the preform is widened to a maximum width of a cross section of the shaped sheet metal part produced after the O-forming.
