Abstract

1394058 Drawing BRITISH INSULATED CALLENDER'S CABLES Ltd 21 July 1972 [20 July 1971] 34031/71 Heading B3P A wire drawing machine includes at least one drawing block having a tapered surface for drawing a wire 4 through each of at least two dies, an independently adjustable drive means for each block having a working range in which the angular velocity of the block can change in response to speed variation of the wire engaged therewith and independently of the other blocks and means 16 for taking up drawn wire from the last block 14. In one embodiment, a wire 4, e.g. 0À04 mm. diameter copper wire, is passed through a first die 6 and around upper and lower blocks 2, 3 in a single loop 7 and so on until it reaches the final block 14, from where it is fed to a takeup reel 16. Alternative threading arrangements are shown in Figs. 6-9 (not shown). Each drawing block may have a concave surface or be formed by an aluminium oxide or tungsten carbide coated metal ring (24) (Fig. 10, not shown), which has an external surface (23) with a taper of 0À3-10 degrees and which is mounted between members (25, 26) threaded on a drive shaft (27) driven by a rotary displacement pneumatic motor. The exhaust air from the motor escapes through ports (32) to keep the block free from dust and lubricant. Alternatively, each block and reel 16 are coupled to an impeller 18 which is rotated by a liquid jet or air jet supplied from an air compressor 19 via a valve 20, a manifold 21 and valve 22. The valve 20 can be operated by a foot pedal to facilitate the threading up operation. After the wire 4 has been threaded through the machine, the pressure at the regulator 19 is adjusted to drive the blocks at 250 r.p.m., after which the speed of the reel 16 is adjusted by its associated valve 22 to cause slip between the wire and at least some of the blocks, the wire moving down the tapered block surface without stretching. Subsequently, the speed of each block at which slip occurs starting from the last block 14, is reduced by its associated valve 22 until the slip is eliminated. The air supply pressure is then raised to accelerate the machine to full speed. The drawing blocks may alternatively be driven by electric motors.
