Development of continuous die drawing production process for engineered polymer cores for wire ropes |
| |
Abstract: | AbstractThe process of continuous die drawing has been adapted as the means of production of polymer cores for wire ropes. The cores have a precisely engineered cross-sectional shape, which is produced by the die drawing process. In order to control this shape accurately, the drawing is carried out in two stages, first drawing in a heated circular conical die and secondly in a cooled fluted conical die. A production line has been developed, which produces core at commercially acceptable rates and with precisely controlled dimensional and mechanical properties. The polymer core serves as a replacement for the three strand cores made from natural fibres. |
