Abstract
A wire drawing apparatus includes a container having opposing front and rear sides. The front and rear sides each have an opening formed therein. A quantity of dry powdered lubricant is located in the container. A die is positioned adjacent the opening on the rear side of the container. A wire is inserted in the opening in the front side of the container. The wire is pulled through the container and through the die. A permanent magnet is adjustably mounted in the container. Both the wire and the dry lubricant are magnetized by the magnet thereby causing the wire and lubricant to be attracted to one another so that the lubricant is held by the wire as the wire is pulled into the die.
