    摘要： A threading die (100) for cold-drawing a metal wire (4) is described; the threading die comprises a hole (103) for the inlet of the wire to be drawn and the hole comprises a conical part (106) for drawing the metal wire and a truncated-cone shaped part (105) which precedes the conical part in the advance path of the metal wire and wherein no decrease in the diameter of the metal wire occurs; the base with the greater diameter (111) of the truncated-cone shaped part precedes the base with the shorter diameter (112) in the advance path of the metal wire.

    摘要： A drawing machine (1) for drawing a tube (2), defining a longitudinal axis (Y), comprising a first die (3) for carrying out the drawing of the tube by means of the use of a mandrel (4); a device for varying the inclination (5) of the tube inlet into said first die (3); a second die (6) for carrying out a skin pass operation on the tube, arranged downstream of said first die (3); an in-line system for detecting the eccentricity of the tube; a data processing system (7) for processing signals originating from said detection system and sending input data to said device for varying the inclination (5) of the tube to vary the inclination of the tube so as to correct the eccentricity of the tube in-line; wherein said in-line system for detecting the eccentricity of the tube comprises a first detection head comprising at least three first transducers (8) arranged downstream of said first die (3).

    摘要： A wire drawing die assembly has removable pressure and draw nibs held in screw-together holders. The pressure nib projects somewhat from its holder and presses the draw nib into a converging passageway in the draw nib holder. A lubricant pressure chamber 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 can be separated and the worn nib can be readily replaced.

    摘要： A filament drawing device for drawing a plurality of strands simultaneously in a downstream direction through a plurality of groups of dies, there being one die for each strand. Each group of dies is held in a retaining mechanism including first and second portions which are adapted for movement toward and away from one another. When the retaining mechanism is in the open position, wherein the portions have been moved away from each other, any one of the plurality of dies may be removed without removing or displacing other dies in the same group. When the portions are moved toward each other, they overlie at least partially the dies in the group and thereby retain them in position.

    摘要： A method for cooling a steel wire which is being drawn in a dry lubricant wire drawing operation wherein the rear portion of the die, including the backrelief portion thereof and the wire which has just been drawn to the desired dimension, are brought into direct contact with a cooling medium so as to effect forced cooling thereof, the wire thereby being cooled before the commencement of strain-aging embrittlement within the wire.
