High-pressure bulge-forming apparatus for producing complex-shaped hollow articles, has fasteners that releasably secure heads on stems of actuators aligned with cavity ends of multipart die assembly

摘要

The apparatus has a multipart die assembly (1) formed with a cavity (13) for receiving a hollow workpiece. Respective actuators (10), with stems (11) axially extended toward the cavity, are aligned with the cavity ends. Respective heads (12) engage in the cavity with the ends of the workpiece. Fasteners releasably secure the heads on the stems.
