Abstract (en)
[origin: US6227024B1] A flow-forming device includes a forming device having a cage in which a plurality of rolling members are rotatably arranged in ring-like manner about a rotation axis. A spinning chuck is configured to hold a blank so as to be axially displaceable relative to the forming device. A drive is provided for rotating the blank relative to said forming device. A method for flow-forming includes rotating at least one of the blank and the rolling member about a rotation axis and flow-forming the blank through contact with a plurality of rolling members which are arranged in a ring-like manner around the rotation axis and mounted in rotary manner in a cage.
