Method for making a pressure tank

摘要

The method involves fitting the enveloping body with its inner diameter area on one side on a die plate (33), where the die plate has a raised wedge profile. The external diameter area of the enveloping body is attached on a support surface (29). The enveloping body is filled with a pressure medium, by which the enveloping body is tensioned on the die plate and is plastically deformed in the area of the wedge profile. An independent claim is included for a device for manufacturing a pressure container.
