Closed-frame type pipe-bending press

机译:闭框式弯管压力机

摘要

A pipe-bending press with a large bending length in a closed frame construction, has a frame with side columns and upper and lower cross- pieces. The table supporting the lower bending tools is supported at the lower cross-piece and the upper bending tool which is guided vertically at the side columns in a parallel manner is supported via a plurality of identical piston/cylinder units arranged side by side so that the upper bending tool can be raised and lowered relative to the upper cross-piece. The cylinder spaces of the piston/cylinder units are connected to a common pressure medium unit via a common control line, and the lower piston/cylinder units are arranged between the table supporting the lower bending tools and the lower cross-piece.
