Abstract:
To provide methods, apparatuses and drawing mandrels in which the shaping process can be monitored as closely as possible, a drawing machine and a drawing method manufactures or processes tubes, which extend in the direction of longitudinal extent, from a semi-manufactured product, wherein the drawing machine includes a drawing device for drawing a hollow workpiece formed by the tube and the semi-manufactured product in the direction of longitudinal extent, a drawing ring and a drawing mandrel and acts on the workpiece in a shaping manner via the drawing mandrel and the drawing ring while the workpiece is drawn by the drawing device around the drawing mandrel and through the drawing ring. A sensor is located on the drawing mandrel, or physical properties are measured in the interior of the workpiece and/or on the drawing mandrel using a sensor on the drawing mandrel.
