Abstract
1388732 Drawing BENTELER-WERKE AG 16 June 1972 [30 June 1971] 28283/72 Heading B3P [Also in Division G3] In a method of drawing a workpiece 2 such as a tube through a train of drawing dies 3 by a rotary drawing element 4 for each die, the tension of the workpiece 2 between consecutive drawing elements 4 is controlled by controlling the speed of the elements 4 by electrical signals representing the forces occurring at the elements 4 and dies 3. The peripheral advancing force of each drum 4 is measured by an electric load cell 10 which is mounted on the drive shaft 9 of the drum 4 and which has a projecting pin 10a engaging an abutment 11 on the inside of the drum 4. The force on each dieholder 12 is measured by a load cell 16 attached at 17 to a frame 13 and articulated to the dieholder 12. The upper end of the dieholder 12 is pivoted to the frame 13 which is supported on a roller 18 and is pivotable about a vertical shaft 19a and a horizontal shaft 19 so as to ensure proper alignment of the die 3. The output voltages of the load cells 10, 16 for each drawing stage are fed through amplifiers 30, 31 to a differential amplifier 32 whose output is compared in a circuit 33 with a selected signal from a potentiometer 33a. The output signal of the circuit 33 is superimposed upon a signal representing any difference between a signal from a tachogenerator 22 and a selected signal from a potentiometer 35 and fed to a regulator 36, which controls the speed of the drum motor 5. The output of the differential amplifier 32 is also transmitted to the input of the amplifier 32 associated with the preceding drum 4.
