Definitions

  • the present invention relates to a device for ensuring the internal and external quenching of tubular metal parts and more particularly of steel tubes. It is known that in the manufacture of steel tubes, the quenching constitutes a particularly important qualitative element and that it poses a certain number of technical problems difficult to solve, among which we can cite for example: - obtaining good homogeneity between the inner quenching and the outer quenching; - obtaining minimum deformation during quenching; - the achievement of an excellent surface finish.
  • this invention relates to an internal and external quenching device for tubular parts, in particular steel tubes, characterized in that it successively comprises in the direction of advancement of the tubes: - inclined rollers allowing the continuously delivered tubes to advance successively by turning around their axis; - an external quenching system; - a tube clamping and locking system; - A retractable carriage supporting an injection lance for carrying out the internal quenching, this carriage being provided with said clamping and blocking system of the tube; means allowing the carriage to move back with the tube clamping system, to accompany the latter on the move, while the internal quenching takes place, and - retractable rollers, coming into position to support the tube, as the carriage moves back while releasing the tube from the external quenching system.
  • the tube clamping and blocking system is integral with said carriage and it comprises: a hollow nozzle into which the injection lance opens for the internal quenching, this hollow nozzle having a frustoconical bearing on its arranged face facing the inner quenching system, in order to block the front end of the tube and clamps mounted to tilt on said end piece and coming to tighten the tube when the latter comes up against the end piece.
  • the carriage is mounted on a frame by means of arms, moved by jacks, said frame moving on a raceway, for example using a rack and pinion system .
  • the device according to this invention comprises a set of inclined rollers (a single roller 10 is visible in FIG. 1) supporting the tube during its advancement so that it can rotate freely around its axis and be delivered to an external quenching system 12 of conventional type comprising supply lines 14 for quenching liquid leading to a plurality of injection nozzles 16, distributed longitudinally along the path of the tube T and arranged in rings around it. latest.
  • a retractable carriage 18 is provided on which the lance 20 is mounted ensuring the injection of the quenching liquid inside the tube T, this lance being supplied by the line 22.
  • the carriage 18 is suspended from a frame 24 by means of oscillating arms 26, moved by jacks such as 28 and it can move longitudinally, in the direction of advancement of the tube T, by means of pinions 30 engaged on racks 32 mounted on a gantry 34, supporting the entire carriage.
  • the lance 20 is provided with a nozzle 36 which can rotate freely around its axis thanks to a rotating joint 40 and which has a frustoconical bearing surface 38 on which the end of the tube T is applied and blocked as will be described below. -after.
  • On this end piece 36 are mounted tilting clamps 42.
  • these clamps 42 are mounted on a stirrup 46 so as to be able to tilt around the axis 44 and they have on their rear part a inclined plane 48 coming to bear on a frustoconical surface 50 provided on a sleeve 52 mounted on the injection lance 20.
  • This sleeve 52 is biased against the nozzle 36 using a jack 54 mounted on the carriage 18 and coming to act on an articulated lever 56 whose end carries a ring 58 positioned in an annular groove 60, so that the end piece 36 - sleeve 52 can rotate around its axis during the internal quenching of the rotating tube T .
  • the device comprises a plurality of retractable rollers 62 for the evacuation of the tube after quenching.
  • the tube T arrives by turning on itself supported by the inclined rollers such as 10 and it passes through the external quenching system 12.
  • This system 12 At the exit of this system 12 its anterior end abuts on the end piece 36 and is blocked by centering in the frustoconical surface 38 provided at the end of this nozzle.
  • the clamps 42 of the tube are actuated by means of the jack 54 which, by slightly moving the sleeve 52 relative to the end piece 36, causes the clamps 42 to tilt around their axis 44, thanks to the two inclined surfaces 46, 48, sliding one over the other.
  • the quenching liquid is injected inside the tube by the lance 20, while the carriage 18 moves back on its raceway thanks to the pinion system 30 - rack 32, allowing everything the whole to accompany the end of the moving tube.
  • the retractable rollers 62 come into position to support the tube in movement.
  • the clamps 42 are opened by the jack 54 to release the end piece 36 and the jack 28 is actuated in order to retract the carriage 18 by pressing it against its frame 24 suspended from the gantry 34, and clearing the roller track 62.
  • the whole assembly is returned to its starting position to process a new tube.
