Abstract
Process for producing a tubular component which comprises sections which are intentionally different from one another with regard to one or more aspects selected from the group consisting of aspects including material, thickness, size, more specifically circumference or diameter, and the like, and hydroforming of the component, in which process the component is produced by rolling up a substantially flat sheet, which flat sheet substantially corresponds to a flat blank of the tubular component.
Claims15
Process for producing a tubular component having, over at least part of its length, a widening or tapering section comprising the steps of:
- joining together flat sheet parts which differ from one another, at least one of the sheet parts being trapezium-shaped,
- bringing together opposite edges of the joined sheet parts and joining the edges in such a manner that the tubular component formed in this way can be hydroformed, and
- hydroforming the component.
