Abstract
In order to increase safety with regard to methods for processing drawn materials, the invention proposes a method for processing drawn materials, especially rod- and tube-shaped metal drawn materials in which the drawn material is drawn through drawing dies using a multi-stage drawing unit and the drawn material is supplied continuously to a final production stage after leaving the multi-stage drawing unit.
Claims9
A method for processing drawn material (110;
- 210;
- 310;
- 410), especially rod-shaped or tube-shaped metal drawn material, comprising
- drawing the drawn material through a plurality of drawing dies (105, 106;
- 205, 206;
- 305, 306;
- 405, 406) by means of a multi-stage drawing unit (101;
- 201;
- 301;
- 401) and
- the multi-stage drawing unit comprises at least two drawing devices (103, 104;
- 215, 216;
- 303, 316;
- 415, 404) each of which comprises a caterpillar traction device and each arranged after one of two drawing dies, which each introduce a principal drawing force into the drawn material in order to draw this respectively through the drawing die mounted before the respective drawing device, and
- continuously supplying the drawn material to a final production stage (102;
- 202;
- 302;
- 402) directly from and after leaving the outlet of the caterpillar traction device.

A drawn material production installation comprising
- a multi-stage drawing unit (101;
- 201;
- 301;
- 401) in which the multi-stage drawing unit comprises at least two drawing devices (103, 104;
- 215, 216;
- 309, 316;
- 415, 404) each of which comprises a caterpillar traction device and each arranged after a drawing die and comprising a final production stage (102),
- and wherein an outlet (108;
- 208;
- 308;
- 408) of the drawing unit is arranged with respect to an inlet (109;
- 209;
- 309;
- 409) of the final production stage such that drawn material passes from the drawing unit and directly from the outlet of the caterpillar traction device to the final production stage inlet.
