Construction of Wire—Wound Type 30, 000-ton Press Frame

Abstract

A wire-wound type press frame capable of producing up to 30, 000ton forces was constructed. The press stand was wound with 390km of piano wire (6mm x 1.5mm) under a tension of approximately one ton. The pre-compressive force acquired by the frame from the wire winding was calculated to be 39, 000tons. The frame weighs 160tons which is quite light relative to conventional presses.
