フローフォーミング方法および装置
Document Type and Number:
Japanese Patent JP4055850
Kind Code:
B2
Abstract:
A flow-forming method and apparatus, in which a blank is placed on a rolling mandrel of a flow-forming machine, the blank is rotated relative to at least one flow-forming roll, the at least one flow-forming roll is infed radially and/or axially relative to the blank, and the blank is axially lengthened by the flow-forming roll and flow-formed to a workpiece. The method and apparatus compensate dimensional variations of the blank by working at least one compensating area into the workpiece, determining, before and/or during flow-forming, geometrical data of the blank and/or workpiece with a measuring device, obtaining a desired final geometry of the workpiece by individually calculating the geometrical parameters of the at least one compensating area as a function of the geometrical data determined, and controlling the infeed of the flow-forming roll in accordance with the calculated geometrical parameters of the compensating area, so that a workpiece with the desired final geometry can be formed independently of dimensional variations of the blank.
