The bending unit comprises a fixed counterblade (2), a metal sheet holder (3) which, pressing on counterblade (2), holds one of the edges of metal sheet (12) and a blade (1) arranged on the same side of the metal sheet holder (3) as the metal sheet (12), which, translating with respect to the counterblade and to the metal sheet holder, causes the displacement outside the plane of the edge of the metal sheet which is not held by counterblade (2) and metal sheet holder (3). Counterblade (2) and blade (1) are made in a plurality of segments (6, 4) parallel and side by side to one another in a direction orthogonal to the plane of the sheet of metal sheet (12) and the metal sheet holder (3) is so flexible as to follow said counterblade (2) in its deflections.

The station comprises a revolving table (7) for receiving, positioning and clamping in an operating position a pallet (5) of the type provided with adjustable anchoring elements (19) for components of clamping fixtures, a magazine (12) for modular components (82, 88, 100) of clamping fixtures and a robot (13) capable of executing adjustment functions of the anchoring elements (19) of pallet (5), of the clamping and transfer of the modular components (82, 88, 100) and of the application to and separation from the components themselves with respect to anchoring elements (19) of pallet (5). There is provided a control centre (14) with a computer, whereby just one operator may automatically and repetitively execute the work for the entire station.
摘要:
Bei einer Vorrichtung zum Abkanten von Blechzuschnitten ist ein Niederhalter (4) mit einem Niederhaltestempel (5) aus mehreren Segmenten (6) vorgesehen, von denen die zu beiden Seiten eines Mittelsegmentes (7) vorgesehenen Segmente (6) parallel zur Abkantachse verschiebbar gelagert sind. Um das Mittelsegment vorteilhaft aus der Segmentreihe entnehmen zu können, trägt der Niederhalter (4) einen in Richtung der Niederhalteranstellung verschiebbaren Schieber (11), der eine zumindest einseitig offene Schiebeführung (10) für das Mittelsegment (7) aufweist. In der angehobenen Ruhestellung des Schiebers (11) schließt an den Schieber (11) eine Wechseleinrichtung (13) für die Mittelsegmente (7) an.

The pallet comprises one or more supporting faces (3), each of which is provided with an anchorage system for equipping the clamping fixture of a rough piece (61) to be machined with machine tools. Each supporting face (3) has a plurality of anchorage means (4) for components (29, 30, 82) of said clamping fixture. Each anchorage means (4) may be adjusted as to height and as to angular orientation and is connected with a supply of fluid. Said adjustment is carried out by screwing and unscrewing said anchorage means (4) in corresponding appropriately threaded holes (5) in the supporting faces of the pallet.
