Abstract
A punch press provided with a tool magazine in which a plurality of tool mounting gondolas are supported movably in a vertical loop by and between two endless chains arranged vertically around sprocket wheels. Each gondola is supported at its supporting points which differ from each other at least in height, whereby the gondola is moved around in the loop without overturn when the sprocket wheels are rotated by a motor. Each of the gondolas stays at a manually tool changing location of the magazine where a table is provided for changing a number of tool assemblies in the magazine. The table has at least one guide which is positioned at two different heights, and along the guide tool assemblies or an upper and a lower die holders are drawn out of the gondola horizontally and placed in desired positions for replacement.
