Definitions

  • the third model consists in a pressure drawing spinneret set as the one described in the second model, with the difference that the cores may be dismounted and replaced, and the frame may be reused.
  • the lubricant for the pressure drawing spinneret is forced by pressure to be introduced in the lubricant pressure chamber defined between the pressure core and the drawing core.
  • the invention proposes a drawing spinneret comprising at least one drawing core that is made up of a centred through-opening in an axial direction with a shaping neck where at least one inlet portion with a truncated-cone shape forming part of the centred through-opening converges, the drawing core being immobilized on a support structure.
  • the wall of the tubular extension of the front frame is made up of several longitudinal slots that enormously facilitate the radial tightening against at least the drawing core.
  • the coupling of both frames creates a radial tightening at least on the drawing core by contacting the truncated-cone surfaces of both frames.
  • a front end of the drawing core acts as axial stop against the peripheral step of the front frame, selected between the first peripheral step and the second peripheral step.
  • the related frames When the drawing core is worn out, the related frames may be unscrewed and the worn out core may be easily extracted from the cylindrical hole of the front frame and replaced.
  • the rear frame (4) features a bowl-shaped structure whose inner lateral side (7) comprises a conical configuration converging toward its bottom (8) which contains in its centre an outlet through-perforation (9) diverging outwards.
  • the rear frame (4) has an outer truncated-cone surface (25) that converges towards the drawing direction to simplify the design of the die holder and the female threading (6) in their front ends to receive the front end of the front frame (3) which has the male threading (5).
  • the inner lateral side (7) of the rear frame (4) is extended backwards from the female threading (6) to receive the tubular extension (11) of the front frame (3) which has an outer conical surface.
  • the rear frame (4) has an inner and converging conical surface to be received by the outer converging conical surface of the tubular extension (11) of the front frame (3).
  • the lubricant is introduced through the converging inlet (19) for the lubricant by means of the thread or rod to be drawn (24a) itself and an initial conical widening (21 a) and the central trough-opening of the pressure core (2) that ends in the lubricant pressure chamber (30) that is formed by the junction of the outlet portion (22) diverging from the pressure core (2) and the converging inlet portion (27) of the drawing core (1).
  • the pressure level developed by the lubricant retained in the lubricant pressure chamber (30) will depend on the original diameter (24a) difference between the inlet thread (24) upon being drawn and the passage neck (23) of the central through-opening of the pressure core (2).
  • the invention is applicable to a wide array of drawing sets and it is evident that this provides a simple way of replacing worn-out cores (1-2) and an optimum use of the frames (3) and (4).
