Abstract: A Wire-drawing apparatus with one or more drawing-disk drums with an associated drawing-disk drum drive motor. The wire-drawing apparatus has a machine frame that is horizontally divided and comprises a drawing disk upper part with access auxiliary devices, such as a suction extraction device and a drawing die mount, and a lower frame. The wire-drawing apparatus also comprises a covering hood associated with each drawing-disk drum. The wire-drawing apparatus further comprises a centrifugal rim at the bottom of the drawing disk drum that runs at an acute angle in relation to the drawing disk drum axis.

Abstract: A wire-drawing apparatus, having a cover (4), with a drawing-disk drum (1) with cooling being disposed above the cover (4), and a drawing-disk drum drive motor (9) and supply and discharge lines for the cooling also being provided. The invention moreover also relates to a drawing-disk drum (1) for such a wire-drawing apparatus (3). The drawing-disk drum drive motor (9) is disposed beneath the cover (4), while at the same time supply and discharge lines are accommodated beneath the cover (4) on both sides, namely the operating side and the rear side. Thereby the supply lines are routed through the drawing-disk drum drive motor (9), which is configured as a synchronous electric motor.

Abstract: A stretching machine (21) for the production of discontinuously stretched wire (31) comprises a rolltype straightening mill (22), a first roll-type advancing unit (23), a first clamping device (24), which is capable of being moved on a hydraulic linear booster (25), and a second clamping device (28), to which a cutting device (29) is attached. A pushed-in rolled wire (31) to be stretched is prestraightened by the roll-type straightening mill (22) and is advanced to the second clamping device (28) by the first rolltype advancing unit (23). Subsequently, the wire (31) is held by the two clamping devices (24 and 28), the first clamping device (24) being moved opposite to the push-in direction by the amount of a degree of stretching and correspondingly cold-forming the rolled wire. By means of the apparatus, a favourable yield-point ratio is achieved, the strain properties being maintained.
