Abstract

1,010,483. Drawing tubes. M. VON BUSHE, and T. ALTENBRACHT, [trading as T. H. KIESERLING & ALBRECHT]. Aug. 27, 1962 [Sept. 2, 1961], No. 32881/62. Heading B3P. In a method of drawing thin-walled non- ferrous tubes by successive drawing operations the return movements of the tubes, in which they are passed over the mandrels for the next draw, occurs along the drawing axis. An apparatus for performing the method comprises four sets each of mandrels 2a, 2b, 2c, 2d mounted in a drum bench 1. Four sets of co-operating pulleys 4, 4a, 5, 5a are provided for passing the tubes over the mandrels, which are held in position by pulleys 6, and adjustable pressure rollers 6a. The dies 9a, 9b, 9c, 9d are mounted in a turret 9 (Fig. 3) which also has a set of holes 9e through which the tubes can pass freely. On both sides of the turret 9 are driving pulleys 10, 11 and 12, mounted on pivoted arms and which are moved to the operative position by double-acting pistons 18 and 19. In the drawing position the tubes 3 are supported by pulleys 20 which after the final drawing operation transfer the tubes to transverse conveyer belts 23 below the track 21 of the drawing carriage 22. Operation.-Three tubes are passed over the mandrels 2a, the drum 1 is turned through 180 degrees to bring the tubes to the drawing position and they are pushed into the corresponding dies 9a. After the draw the drum and the die turret are turned to bring the mandrels 2b and the passages 9e on to the drawing axis and the pulleys 10, 11 and 12 are then moved to engage the tubes and return them along the drawing axis and pass them over the mandrels 2b. The cycle of operations is repeated until the tubes have been drawn through the four dies.
