发明名称	Forming tool for internal high pressure forming of hollow profiles has elastic seal to close profile opening, loaded by high-pressure forming fluid and additional pressure spring
摘要	The tool uses a fluid at high pressure. One opening of the profile is closed by an elastic seal, which is loaded by a pressure body. The pressure body (7) is subjected to the fluid pressure to move it into sealing position, and by an additional power-generating pressure spring (15), to increase the contact pressure on the seal (4). The contact faces (5,6) between pressure body and seal are wedge-shaped, generating a radial force to increase the sealing force.
