Abstract: In the case of a caterpillar track drawing machine having a drawing die and a caterpillar track disposed behind the drawing die, which track comprises two drawing chains having drawing tools disposed on chain links of the drawing chains, it should be possible to align the drawing tools of at least one of the two drawing chains jointly with the respective chain link, perpendicular to the drawing line, so that the caliber range can be changed, in simple and operationally reliable manner, between two drawing recesses having different caliber ranges. The latter is also possible if two different drawing recesses of the second one of the two drawing chains are intended for a first caliber range for which the first drawing recesses for at least one of the two drawing chains are intended, or if the drawing recesses of a first one of the two drawing chains deviate from the drawing recesses of a second one of the two drawing chains.

Abstract: A caterpillar track drawing method includes drawing a workpiece through a drawing die using a caterpillar track disposed behind the drawing die as seen in a drawing direction; and drawing a workpiece along a drawing line aligned parallel to the drawing direction while forming the workpiece by the drawing die. The caterpillar track includes circulating first and second drawing chains including chain links circulating parallel to a drawing plane. Each drawing chain is guided around first and second chain wheels having first and second axes aligned perpendicular to the drawing plane At least one measurable variable, inherent to the caterpillar track, of modules of the caterpillar track that resist or apply drawing force is recorded and optionally used for activation of a manipulated variable. In another aspect, a caterpillar track drawing machine includes the drawing die, the caterpillar track, and at least one measurable variable recorder.

Abstract: The invention relates to a drawing die arrangement having a drawing tool that acts on an elongated workpiece, and having a drawing tool support on which the drawing tool is mounted, counteracting the drawing tool, in which support a measurement device that measures the mass distribution of the workpiece material is disposed on the drawing tool, wherein a coupling medium circulated between the measurement device and the drawing tool is provided. Furthermore, the invention relates to a workpiece guide and to a drawing system.

Abstract: A drawing system and a method for automatically operating a drawing system. At least one quality-relevant feature of a drawn product, selected from a group of features including the straightness of the drawn product, the length of the drawn product, the diameter and/or at least a thickness of the drawn product, the roundness of the drawn product, and the surface quality of the drawn product, is measured by at least one quality sensor, and the obtained measurement value is processed in at least one control circuit which acts on at least one quality-relevant manipulated variable of the drawing system or parts of the drawing system via at least one controller., At least one reference variable for at least one quality-relevant feature of a specific drawn product is processed in a process controller.

Abstract: In order to increase the operational safety of an unreeling apparatus and an unreeling method at high working speed, an unreeling apparatus for unreeling a ring of wire along a pull-off direction, having at least two reel crowns, which can each be brought into a pull-off position and into a preparation position and/or loading position by way of a displacement device, includes a safety apparatus having an overload safety device and having a safety guide track, which has a directional component that faces in the pull-off direction and acts independently of the other reel crown, at least for the reel crown situated in the pull-off position, wherein the overload safety device holds the reel crown situated in the pull-off position in the pull-off position and, in the event of an overload, releases the reel crown situated in the pull-off position into the safety guide track.

Abstract: A caterpillar-traction drawing machine and a method for drawing of elongated workpieces can be provided with at least one drawing tool fastened pivotally on a tool holder and/or with at least two identical drawing recesses, which can be brought selectively into a drawing position, so that the influence of any fatigue phenomena at may exist is minimized. For the same reason, a caterpillar-traction drawing machine is advantageous in which the two chains of the caterpillar-traction unit are block chains and are respectively braced via an idler roller chain including idler rollers on respectively one pressing beam.
