Definitions

  • a drawing device with hydrocynamic lubrication designed for drawing wires, rods, and tubes made of metals and alloys, is provided with a universal centering system, intensive cooling of the drawing dies, and vi sual inspection means for the seal of the drawing dies in the course of operation of the drawing device.
  • Labyrinth-type recesses form the sealing system between the drawing dies and the pressure sleeve, which are designed for simultaneous alignment of these members against each other.
  • a chamber is formed between the system of drawing dies and the inner surface of the body, which chamber forms a system for the cooling medium to contact directly the outer surface of drawing dies. At least one inspection opening is provided on the drawing die body.
  • FIG. 1 is a longitudinal sectional view of the drawing The present invention relates to a drawing device 5 device of the present invention.
  • hydrodynamic lubrication designed for drawing wires, rods, and tubes made of metals and their alloys, provided with a universal centering system, intensive die cooling, and means for visual inspection of the seal of the drawing dies during their operation.
  • a disadvantage of the known drawing die systems is the difficulty in axial alignment of tandem drawing dies, and in axial alignment of the drawing dies and the pressure sleeve in the case of a drawing machine with hydrodynamic lubrication.
  • the drawing dies must be specially fitted by turning the outer surfaces of their mountings and of the pressure sleeve. ln centering, only the cylindrical side surfaces of the drawing dies and of the pressure sleeve are capable of being engaged.
  • a fourth disadvantage of the known drawing dies systems is the impossibility of inspecting the seal between the drawing dies during their operation.
  • the object of the present invention is to provide a drawing die system with hydraulic lubrication which admits drawing dies into its body without the previously necessary fitting of their outer dimensions or of their conical side surfaces, with a simultaneous increase in the exactness of the central alignment of the drawing dies and the pressure sleeve.
  • Another object of the invention is to increase the cooling intensity of the drawing dies, and to provide for inspection of the seals of the drawing dies during their use.
  • the drawing device has a chamber formed between the drawing die system and the inner surface of the body, which chamber, being suitably sealed, provides a system whereby the cooling medium directly contacts the outer surface of the drawing dies and removes the heat generated by the drawing operation.
  • the drawing device is provided with at least one inspection opening for inspection of the coolant circula- FlG. 2 is a longitudinal part-sectional view of the drawing device of the present invention.
  • the drawing device consists of drawing dies 1 and pressure sleeve 2 provided with projections 4 and recesses 3, which are partitioned with the seal 8 during the drawing operation.
  • the drawing dies 1 and the part of the pressure sleeve 2 situated within the body 5 have diameters smaller than the inner diameter of the body chamber 5.
  • a chamber 6 is formed between the outer surface of the drawing dies 1 together with the pressure sleeve 2.
  • the chamber 6 contains the cooling medium which is introduced to and drained from the chamber 6 through connector pipes 10.
  • the inspection opening 7 is fitted onto the body 5.
  • the drawing device of the present invention operates as described hereinbelow.
  • the material to be drawn in the form of wire, rod, or tube, 11, is drawn from the pressure sleeve 2 towards the drawing dies 1.
  • the effectiveness of the seal is checked through the inspection opening fitted on the drawing die body 5.
  • the heat generated in the process of deforming the material 11 being drawn is removed by the cooling medium supplied to the chamber 6 and is drained from the chamber through connector pipes 10.
  • the cooling medium contacts directly with the surface of the drawing dies 1 and of the pressure sleeve 2, thus providing the most efficient cooling system. Seals 9 are provided to seal the cooling system.
  • the advantage of the drawing device of the present invention is its university, as it permits the use of conventional drawing dies as working tools without the necessity of turning their side surfaces, and, simultaneously, it ensures exact axial alignment of the drawing die holes and the pressure sleeve.
  • Apparatus for drawing wires, bars, and tubes comprising a housing containing and surrounding a pressure sleeve and drawing dies in tandem alignment with labyrinth undercuts; gaskets sealing lubricant chambers between said drawing dies and (a) said pressure sleeve; an internal chamber for water cooling of said drawing dies and said pressure sleeve wherein labyrinth sealing undercuts are the only means for centering the tandem alignment of said drawing dies and said pressure sleeve, and wherein said internal chamber extends the axial length of said drawing dies and said pressure sleeve and is formed by internal walls of said housing, by external cylindrical surfaces of said drawing dies, and by the external cylindrical surface of said pressure sleeve.
