Description
Components such as cables, screws, nails and many other things vital for our modern society are made from cold drawn wire. The wire is produced by pulling hot rolled wire through a single or a series of tools called drawing dies. In this process the cross-section of the wire is reduced, and the mechanical properties of the material is enhanced. Even though it is classified as a cold working process, there are rather high temperatures in the dies due to extreme tribological conditions resulting in high frictional forces between the wire and the die.
Studies have shown that the temperature of the drawing tool has an impact on the productivity of the drawing process. High temperatures cause lubrication degradation resulting in damages on the dies and the produced product. It has been shown that with a decreased tool temperature the productivity could be increased, and the tool wear rate decreased.
In this poster, case studies are presented in which the benefits from additive manufacturing have been utilized to improve the cooling capacity of the drawing dies in industrial wire drawing processes.
