Process to control the drive of a wire drawing machine and wire drawing machine

摘要

The method involves automatically determining the useful torque required for a shaping process at the individual drawing stages for each delivery process for a low and constant speed in slip mode. A reference torque comparison value is derived from the useful torques between two adjacent drawing disks (7). The useful torque is detected at the drawing stages in slip-free production mode and a comparison is made of each two adjacent drawing disks to form a first torque comparison value; comparing the detected first torque with the reference comparison value. There is a deviation of the current first comparison value from the reference comparison value. The drive speed regulation is superimposed so slower drive varies the speed of the associated draw plate until the deviation is essentially null. An Independent claim is also included for an arrangement for drawing elongated metal material, esp. round or profiled wire.
