Definitions

  • the present invention relates to improvements made to pneumatic threading systems for the wire in the bore of a double twist spindle, this bore being provided with a wire brake.
  • the pneumatic threading device has a very small number of parts so that its construction is very economical.
  • the compressed air used by the device according to the invention is introduced into this spindle by its usual bore through which the thread is twisted.
  • the spindle is produced by two tubes joined by a connecting sleeve in which are arranged means for laterally moving the wire brake relative to said bore when the pressurized air is introduced into the latter.
  • the wire brake which is produced in the form of a usual telescopic capsule, then releases the bore and allows a wire placed at the head of the spindle to be freely introduced into its bore.
  • the introduction of the wire is carried out by means of a gun such as that described in the aforementioned French patent 77 22839 of the Applicant.
  • the thread 1a of the tube 1 stops at some distance from its end to determine a smooth cylindrical seat 1b capable of cooperating with an O-ring 4 of the sleeve 3.
  • a ring 5 cooperates with the thread 1a of the tube 1 to determine the relative position of the latter relative to the sleeve 3.
  • the lower tube 2 has a thread 2a which stops before the end of the tube in order to determine a smooth cylindrical surface 2b.
  • the sleeve also includes a seal 4 'for reasons which will be better explained below. Said end is associated with a stepped end-piece 6 pierced through and through and the part with a smaller diameter penetrates into the bore 2c of the tube 2. Between the shoulder 6a of the end-piece 6 and the annular end of the tube 2 a compression spring 7 is placed.
  • the larger diameter part 6b of the end piece 6 is slidably mounted just in the bore 3a of the sleeve 3.
  • the outlet upwards from the central hole 6c of the end piece 6 is chamfered as is the outlet of the bore lc of the tube 1.
  • the outlets considered are connected by the usual wire brake which is produced by means of a capsule 8 formed by two telescopic tubular elements referenced 8a and 8b and the ends of which are each closed by a spherical cap.
  • a compression spring 9 is placed between the two elements of the capsule 8 in order to separate them from one another.
  • the adjustment of the penetration of the tubes 1 and 2 in the sleeve 3 is intended to allow suitable crushing of the spring 9 by penetration of the element 8b inside that 8a.
  • the sleeve 3 is provided with a transverse groove 10 which passes through its central bore 3a to reach a cylindrical housing 11 opening outwards.
  • a piston 12 with a cylindrical head comprising a flat tail 13 which slides with clearance in the groove 10.
  • a plug 14 closes the outlet towards the outside of the housing 11.
  • the bore 3a of the sleeve 3 communicates it with said housing.
  • the latter is roughly rectangular and it comprises two intersecting circular openings one 13a with a diameter greater than that of the other 13b.
  • the outside diameter of the element 8b of the capsule 8 has a diameter greater than the width of the opening 13c making the two openings 13a and 13b communicate for reasons which will be better explained below.
  • the piston 12 Prior to placing the capsule 8 in the sleeve 3, the piston 12 is placed in the position shown in fig. l and 2 so that the capsule 8 can be engaged in the hole 13a of the tail 13 of this piston.
  • seals 4, 4 ′ prevent any air from escaping between the sleeve and the tubes 1 and 2 respectively.
  • a pneumatic threading device has thus been produced in a double twist spindle which is particularly effective while being very modest in cost.
