Abstract:
An apparatus for bending hard-drawn copper conductor bars for turbo-generators and engines, comprising:a swivel arm, which has a displaceable pivot point, an inner bending cylinder and an outer bending cylinder, which are arranged on the swivel arm, the outer bending cylinder comprising a bending jaw and the inner bending cylinder having a shaping jaw and it being possible for a hard-drawn copper conductor bar to be introduced between the bending jaw and the shaping jaw for bending to a predetermined bending radius,a pair of cylinders, which are respectively arranged alongside the inner and outer bending cylinder and between which the bent hard-drawn copper conductor bar can be clamped in, a pair of clamping cylinders, which in turn are respectively arranged alongside the pair of cylinders, for clamping in the bent hard-down copper conductor bar,a measuring system for measuring a bending radius of the bent hard-drawn copper conductor bar and for establishing a deviation from the predetermined bending radius,a device for displacing the pivot point of the swivel arm in response to a deviation from the predetermined bending radius, the cylinders, bending cylinders and clamping cylinders being respectively arranged on a line extending radially outward from the pivot point and the corresponding inner and outer cylinders respectively lying on an arc of a circle, andwherein the measuring system is arranged in the pair of cylinders.
