| 摘要 |
The invention relates to a device for forming a single or multi-chamber workpiece (42) by means of high internal pressure created by a medium capable of flow in the hollow interior (5) of the workpiece. The device contains a forming tool (4) with a cavity accommodating the workpiece (42) and pressure generating equipment (1) for generating the high internal pressure. The pressure generating equipment (1) contains a displacement pump with pressure converter comprising a longitudinally coupled displacement body with different working surface areas A1, A2, which operates with a stroke frequency f, whereby strokes of the pressure converter cause a pressure p1 created on the primary side to be raised until a higher secondary pressure p2 is reached on the secondary side.
