Abstract (en)
[origin: US2003019269A1] The invention relates to a flow-forming method and device for producing a hollow article having a steplike shoulder from a tubular workpiece. For this purpose on the tubular workpiece is formed a conical area, which is selectively heated. Then an axial upsetting force is exerted on the workpiece, so that the heated conical area is upset and formed to the steplike shoulder. Both the shaping of the conical area and the upsetting can be performed on one flow-forming device.
