DISPOSITIFS ET PROCÉDÉ DE FORMAGE PAR PRESSION DE BARRETTES DE LIAISON ENTRE DES PARTIES D'UNE PIÈCE À USINER EN PLAQUES

摘要

A forming tool (13) for pressure-forming a connecting web (23) between incompletely separated workpiece parts (18, 20) of a parting plate-like workpiece, in particular a sheet metal (15), comprises two tool parts which during pressure forming of the connecting web (23) along a lifting axis (14) are associated with opposite sides of the connecting web (23). A first of the tool parts has a forming element (24), the second tool part (12) is provided with a bearing surface (27) extending in the transverse direction of the lifting axis (14) and facing the free end of the first tool part. The support surface (27) of the second tool part (12) is formed as a continuous flat surface. When press-forming the connecting web (23), the support surface (27) of the second tool part (12) the forming member (24) of the first tool part along the lifting axis (14) with a surface area opposite, with the remaining bearing surface (27) of the second tool part ( 12) in the transverse direction of the lifting axis (14) is aligned. By means of the forming tool (13), a method for pressure forming a connecting web (23) is performed. The method for pressure forming a connecting web (23) is part of a method for separating machining of plate-like workpieces, in particular for the separating processing of sheets (15) and also part of a method for processing plate-like workpieces, in particular for processing sheets (15), in Frame of which, in addition to the separating processing, a further workpiece machining, in particular an edge processing is performed.
