High-pressure deformation of two plates into hollow workpiece |
摘要 |
An apparatus for forming two plates into a hollow workpiece has a pair of dies having edge regions adapted to be pressed together against outer peripheries of the plates. An outer element in the edge region of one of the dies is adapted to rotate therein about an axis generally parallel to the direction and an inner element set in the outer element is rotatable therein about an axis generally parallel to and offset from the outer-element axis. The inner element is formed offset from its axis with an axially throughgoing feed passage aligned with a feed hole in the plate engaging the one die. A fluid forced under pressure through the passage and hole into a space between the plates deforms the plates away from each other in the direction while displacing the hole perpendicular to the direction with movement of the passage perpendicular to the direction.
