Patent DE-19830623-A1 (DE)
Title: Hollow workpiece conversion by high pressure medium is aided by outward pressure at reduction point by impressed plunger tool to reduce work to tool friction
IPC: B21D26/02
Filed: 1998-07-09
Abstract: The outer wall of the workpiece (W) is loaded with medium pressure from outside in the positions due for reduction in section and/or the positions exposed to increased friction between work and tool. In addition to this, pressure is applied by medium from within the workpiece.  The supporting pressure counter to that from outside is produced by a plunger (2) containing (2.1,2.2) the reduced section impression. This inside pressure is applied subsequently to the outside pressure stage so the impression of the halves etc. (2.1,2.2) spreads the work metal appropriate to the impression and/or provides supporting pressure and/or friction-reducing pressure and/or so reduces the adhesion between work and tool as to ease the work withdrawal. When using an additional tool, this is run onto the converted work wall so that renewed pressure from within spreads the work to match the impression of the additional tool. Pressing medium comes in along the feed (4) to the necked area (2.3) of the plunger tool (2).
