Kind Code:
B2
Abstract:
PCT No. PCT/EP96/02531 Sec. 371 Date Feb. 7, 1997 Sec. 102(e) Date Feb. 7, 1997 PCT Filed Jun. 11, 1996 PCT Pub. No. WO96/41690 PCT Pub. Date Dec. 27, 1996As part of a process for bending workpieces (14), when the workpiece (14) is released from the upper die (8) and/or the lower die (10), the actual size of the bending angle ( beta ) is continually determined; from the actual size of the bending angle ( beta ) found, the change in it is determined and, as soon as the change in the actual size of the bending angle ( beta ) assumes a predetermined value, the actual size of the then existing bending angle ( beta ) is compared with the desired size. On a tooling machine for carrying out the method described, there are scanning elements (17,18) and a device (24) for determining the actual size of the bending angle ( beta ) that are parts of a device (19) for determining the change in the actual size of the bending angle ( beta ). The device (24) for determining the actual size of the bending angle ( beta ) is connected to a comparison device (32) for comparing the actual size of the bending angle ( beta ) to the desired size.
