IMPROVED MACHINE FOR FABRICATING STEEL WIRE ROPES AND INTERCHANGEABLE WIRE SPOOL CARRYING MODULE FOR USE IN A STEEL WIRE ROPE FABRICATING MACHINE

摘要

The present invention is related to an improved steel wire rope fabricating machine, and to an interchangeable wire spool module intended for use in a steel wire rope fabricating machine. The machine according to the present invention is capable of fabricating in a single operation steel wire ropes for plural applications, of various sizes and types, having cores of different materials such as steel, hemp, synthetic fibers, etc., and is a compact machine, not requiring much space, is relatively lightweight and affords high throughput. Therefore, the present invention provides a steel wire rope fabricating machine comprising at least a wire spool carrying module formed by at least two mutually parallel discs (8, 7), one forward disc (8) and one rear disc (7), mounted in cooperation around the same central shaft (30), the discs (8, 7) providing support to a plurality of rotor shafts (38) being parallel to one another and to the central shaft (30), around which they translate, uniformly relatively to each other proximate to the edge of each disc (8, 7) on which rotor shafts there freely rotate a plurality of wire or filament spools (35) for the fabrication of steel wire rope strands, there also being included a steel wire rope strand core feeding assembly (40, 41) mounted in cooperation at the forward end of each rotor shaft (38), a set of gears (5, 9, 39) to cause the shafts (38) to rotate in a direction opposite to that of the central shaft (30) in a rotation compatible with the desired pitch for the strands during the translation movement of the rotor shafts (38) around the central shaft (30), and coupled to said rear disc (7), a deforming assembly (32) capable of relieving the stresses caused by winding of the various wires upon forming the wire rope strand.
