Internal high pressure deformation plant has support body between upper and lower tools acting against application surfaces of axial stamps sealing ends of hollow profile to be deformed

摘要

The deformation plant (1) has upper and lower tools (2,3) cooperating for defining a mould space (5) for the hollow profile to be deformed and respectively attached to upper and lower plates (7,6) reciprocated relative to one another. At least one axial stamp (8,9) is displaced axially for sealing the end of the hollow profile and opposing the axial force component of the internal pressure, a support body (17) provided between the upper and lower plate cooperating with an application surface (21) of the axial stamp in its sealing position.
