Title:
PRODUCTION DEVICE, ESPECIALLY A BENDING PRESS, AND METHOD FOR OPERATING SAID PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO2003095125
Kind Code:
A3
Abstract:
The invention relates to a production device (1) for workpieces that are formed under bending conditions and consist of billets (3), especially steel sheet billets. Said production device comprises a bending press (2) provided with two pressing crosspieces (15, 16) which have two bending tools (36, 37) and can be adjusted in relation to each other. The bending press (2) is charged using an automated handling device (4). Said handling device (4) comprises three articulated arms (49, 50, 51) which are connected by pivoting devices (46, 47) to form a pivoting arm arrangement (48), and a first articulated arm (49) is mounted in an end region (52) on a linearly displaceable running gear (54) in a pivoting device (55), in such a way that it pivots about a pivoting axis (56) extending parallel to a guideway (53) of the running gear (54). Second and third pivoting axes (57, 58) of the pivoting devices (46, 47) bearing the articulated arms (49, 50, 51) extend parallel to the pivoting axis (56) of the pivoting device (55) on the running gear (54). A gripping device (61) and a detection device (63) for the billets (3) are arranged in another end region (59) of the pivoting arm arrangement (48). A positioning device (66) ensures the positioning of the billets (3) for the bending process.
