Abstract

1384142 Drawing BENTELER-WERKE AG 16 June 1972 [26 June 1971] 28282/72 Heading B3P In a method of drawing a tube through a train of drawing dies 8 by an electric motor driven drawing drum for each die, the tube follows a substantially rectilinear path between the drums and the relative torques of the drum motors are controlled to maintain in the tube section 4a between each die 8 and the preceding drum a predetermined tension providing a counterpull. A steel strip (1) (Fig. 1, not shown) is skelped by rolls (2) and longitudinally welded by a device (3) to form a tube, which is continuously drawn through a number of dies 8 and finally coiled on coilers (7, 7a). The tube may be reduced 30- 50% in area at each die 8 and is passed around each drawing drum once only. Successive pairs of the drums are arranged at right angles to each other, the drums in each pair being positioned on opposite sides' of the tube. A constant counterpull is maintained in the tube section 4a by monitoring the tension in the section 4a by a dancer roll 24 which causes the speed of the motor of the drum 5a to be regulated. Each drawing die 8 is mounted in a holder 10 which is supported on a roller 14 and mounted on a horizontal hinge pin 11 rotatable about a vertical swivel pin in a bearing 12 to. enable proper alignment of the die 8. A floating plug (20, 20a, 20b) (Fig. 4, not shown) is arranged within the tube at each die 8, each plug except the last (20b) in the drawing direction having an axial bore (23, 23a) to allow the passage of lubricant supplied through a pipe (22). Lubricant is also introduced into the tube interior by a pipe (21) and into a sleeve 16 mounted in front of the die 8.
