ADJUSTABLE PRESS TOOL

摘要

The press tool as disclosed is provided for making tubes or pipes at a diameter of 600 millimeters or more and a diameter-to-wall-thickness ratio of 13 or more. In order to permit employment of the tool for a relatively wide range of dimensions without requiring extensive retooling, it is suggested that the tool is comprised of a stationary centerpiece and side pieces, which are hinged to the centerpiece and held in position by spacer bars acting as adjustable cams.
