Problems solved by technology
[0002] In the traditional twisting production of triangular strand steel wire rope, the inner hole of the tapered sleeve forming device used has only one tapered hole area. When the steel wire is twisted into strands, the strands are formed unevenly and the stress is large. It is easy to cause "steel wire deformation" and "back wire" when rolling, making it difficult to arrange the production line, affecting product quality and production efficiency

Embodiment Construction
[0011] The present invention will be described in further detail below in conjunction with accompanying drawing:
[0012] The special tapered sleeve for twisted strands of triangular strand steel wire rope of the present invention, according to figure 1 It consists of a tapered hole area 1 and a straight hole area 2; the height H of the tapered sleeve is 20-35mm, and the outer diameter of the inlet end is Ф 2 40-80mm, outlet diameter Ф 1 Ф10-35mm; the height h of the straight hole area 2 is 8-16 mm, and the aperture Ф 1 10-35mm; the taper α of the tapered hole area 1 is 65 0 -75 0 .
[0013] The preferred solution of the present invention is: the height H of the special tapered sleeve for twisted strands of the triangular strand steel wire rope is 25 mm, and the outer diameter of the entrance end is Ф 2 60mm, outlet diameter Ф 1 is Ф25mm; the height h of the straight hole area 2 is 12 mm, and the hole diameter is Ф 1 is 25mm; the taper α of the tapered hole area 1 is 70...

Abstract
A conical sleeve special for stranding triangular-strand steel wire ropes is composed of a conical hole zone and a straight hole zone, the height of the conical sleeve is 20-35 mm, the outer diameterof the inlet end is 40-80 mm, the outer diameter of the outlet end is phi 10-35 mm, the height of the straight hole zone is 8-16 mm, the hole diameter is 10-35 mm, and the taper of the conical hole zone is 650-750. When the steel wire ropes are stranded, steel wires enter a forming point in the straight hole zone of the conical sleeve in advance and form a strand, the strand surface can be formedmore uniformly under the effect of radial pressure of the straight hole zone, strand wire twisting is tighter, the stress of the stranded ropes is effectively eliminated, the problems of steel wire deformation and drawing possibly caused when the steel wires enter compression rollers are solved, and the product quality is improved.
