WIRE DRAWING DIE ASSEMBLY

摘要

A wire drawing die assembly (10) has removable pressure (14) and draw (18) nibs held in screw-together holders (12, 16). The pressure nib (14) projects somewhat from its holder and presses the draw nib (18) into a converging passageway (38) in the draw nib holder (16). A lubricant pressure chamber (32, 46) is formed between the nibs for lubricant which is introduced through the front end of the pressure nib. When the draw nib becomes worn, the holders (12, 16) can be separated and the worn nib can be readily replaced.
