Abstract
A container degassing device for an extrusion press is equipped with: a integrally formed degassing block joined to the end surface of the container of the extrusion press; a first sealing member that seals the degassing block; a second sealing member that seals the outer peripheral surface of an extrusion stem or a fixed dummy block of the extrusion press; and a vacuum suction device that sucks air from within a degassing space formed within the container. The degassing space is sealed by the degassing block and the first and second sealing members, and the area between the degassing block and the container end surface is sealed by a metal touch.
Claims7
A container degassing device of an extrusion press comprising:
- a one-piece degassing block joined to an end face of a container of the extrusion press;
- a first seal member in close contact with said degassing block;
- a second seal member in close contact with an outer circumferential surface of a fixed dummy block or extrusion stem of said extrusion press;
- and
- a vacuum suction device that sucks out air in a degassing space formed in said container,
- wherein said degassing space is tightly closed by said degassing block and said first and second seal members, and
- said degassing block and said container end face are tightly closed by metal-to-metal contact.

- a one-piece degassing block joined to an end face of a container of the extrusion press;
- a first seal member in close contact with said degassing block;
- at least one second seal member in close contact with an outer circumferential surface of a fixed dummy block or extrusion stem of said extrusion press;
- and
- a vacuum suction device that sucks out air in a degassing space formed in said container,
- wherein said first seal member and said at least one second seal member can move relative to said extrusion stem,
- said degassing space is tightly sealed by said degassing block and said first and second seal members, and
- said degassing block and said container end face are tightly closed by metal-to-metal contact.
