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.
A drawing machine for the production or machining of tubes composed of a semi-finished product, wherein the tubes extend in a longitudinal expanse direction,
A drawing method for the production or machining of tubes composed of a semi-finished product, wherein the tubes extend in a longitudinal expanse direction, wherein using a drawing device, a hollow workpiece formed by the tube and the semi-finished product is drawn along the longitudinal expanse direction and the workpiece is acted on with the drawing mandrel and the drawing ring forming the workpiece, while the workpiece is being drawn around the drawing mandrel and through the drawing ring under the control of the drawing device, wherein a sensor, a micro-controller, and a memory are arranged on the drawing mandrel and the sensor cooperates with the micro-controller and the memory, and the sensor measures a position of the sensor in three-dimensional space,
A drawing mandrel for use in a drawing machine and/or for use in a drawing method for the production or machining of tubes composed of a semi-finished product, wherein the tubes extend in a longitudinal expanse direction, wherein the drawing mandrel is a flying drawing mandrel, wherein a sensor, a micro-controller, and a memory are arranged on the drawing mandrel, and wherein the sensor is configured to cooperate with the micro-controller and the memory and to measure a position of the sensor in three-dimensional space,
