Definitions

  • the present invention relates to a machine for making nozzles and calibrations on the tubes.
  • the main object of the machine according to the invention is to ensure the production of copper risers while respecting the precision standards corresponding to specification B 524 of the Technical Association of Gas of France.
  • said machine according to the invention makes it possible to ensure two functions which are the obtaining of orifices with fallen edges by extrusion on copper tube and the calibration of the bypass tube to be brazed on this orifice over the length necessary for the solder.
  • GB-A patent No. 591662 relates to a machine tool for drilling holes in an injector head.
  • the injector is mounted on a divider plate by means of a clamp, and this arrangement does not allow the tube to be presented coaxially to the spindle for a calibration operation and with its axis perpendicular to the axis of the spindle for drilling and extrusion operations with calibration of a collar outside the tube.
  • patents NL-A No. 74.15559, FR-A No. 1534930 and US-A No. 3081812 are known which relate to an extruder tool comprising a rod provided at its end with a pivoting finger which can occupy two perpendicular positions.
  • the machining tool is held tight in the jaws of the rotary mandrel and on the carriage is pivotally mounted a turret capable of occupying two positions offset by 90 ° and comprising a means of tightening the tube allowing selectively present a tube coaxially to the spindle for a calibration operation and a tube with its axis perpendicular to the axis of the spindle for drilling and extrusion operations with calibration of a collar outside the tube.
  • FIG. 1, 2, 3, 4 and 5 there is shown an embodiment of the machine according to the invention consisting of a bench 1 resting on the ground and supporting, at one of its ends, a fixed headstock 2 on which is mounted a spindle 3 which is provided, at one of its ends, with a rotary mandrel 4, said spindle being connected by a belt transmission 5 to a motor 6 for the rotational driving of the spindle 3 and chuck 4.
  • the mandrel 4 has jaws 7 between which a calibration or extrusion tool may be engaged which will be described in more detail below.
  • the jaws 7 of the mandrel 4 are actuated by means of a fluid such as compressed air and the supply is carried out by means of conduits 21, 21 a (fig. 4) which are connected to a source of compressed air 12 via a control box 23.
  • a support plate 8 on which are mounted, at one of their ends, two bars 9, 9a which are fixed, at their other end, on the headstock 2, said bars 9, 9a constituting slides on which slides, along the longitudinal axis of the bench 1, a carriage 10 which is provided, at its upper part, with a pivoting turret 11 capable of occupying two positions offset by 90 ° as shown in fig. 2 and 5.
  • the turret 11 (FIG. 6) comprises a means for clamping the tubes to be machined which consists of a fixed jaw 12 integral with the body of the turret 11 and a movable jaw 13, between which a tube 14 is held clamped.
  • the movable jaw 13 is provided with a stop 15 having a housing 15a in which is engaged the end of a threaded rod 16 which meshes with a nut secured to the body of the turret 11.
  • the threaded rod 16 is provided with an operating wheel 17 enabling the movable jaw 13 to be actuated by means of the rod 16.
  • the fixed jaw 12 has a bore 18 whose axis is perpendicular to the longitudinal axis of the jaws and into which is screwed a centering tip 19 itself having a bore which opens outwardly through a bore 20 of the body 11 This arrangement allows the introduction of the extrusion tool into the bores 20 and 18 for machining the tube disposed between the jaws 12 and 13.
  • This gear train (fig. 8) comprises a pinion 25 which is wedged on a shaft 26 rotatably mounted between two flanges 27, 28 of the casing, said pinion 25 being driven by the gear 24 and the shaft 26 carrying a pinion 29 which meshes with a pinion 30 wedged on a shaft 31 rotatably mounted between the flanges 27, 28, said shaft 31 being integral with a pinion 32 which meshes with a pinion 33 fixed to one end of a lead screw 34 rotatably mounted between two bearings 35, 35a respectively integral with the housing of the headstock 2 and the plate 8.
  • the mother screw 34 which is rotated from the machine spindle via the gear train, meshes with a nut composed of two half-nuts 36, 36a (fig. 7) which are integral with the carriage by rods 37, 37a on which the half-nuts can slide under the action of the pins 38, 38a which are integral with the half-nuts and which can slide in eccentric slots 39, 39a of a pivoting plate 40 which can be actuated from the outside by a handle 41 (fig. 4).
  • one of the bars 9 comprises a rack 42 which meshes with a pinion (not shown in the drawing) and which is fixed to the end of a shaft 43 which carries at its other end an operating lever 44 capable of to move the carriage 10 manually.
  • two bosses 48, 48a are provided which cooperate with a boss 49 provided on the shaft 45 in order to delimit the two positions.
  • a tool for calibrating a tube said tool consisting of a cylindrical body 50 whose tail 50a is engaged between the jaws 7 of the mandrel 4, said body comprising two bores 50b and 50c in which is engaged a cylindrical centering pin 51 which is held in the body by a screw 52.
  • annular space 53 constituting the calibration space in which is engaged the tube intended to constitute the male part of the tapping.
  • a tool for extruding the tube after drilling a hole by means of a cutter consists of a cylindrical body 54 whose tail 54a is held tight between the jaws 7 of the mandrel 4 and it has a low-cut part 54b on which a sleeve 55 is slidably mounted. Following the low-cut part 54b the body 54 ends with a rod of smaller diameter at the end of which is provided a housing 56 in which is pivotally mounted around an axis 57 perpendicular to the axis of the rod an extruder member 58 having the form of a half circumference.
  • a blind hole 59 In the central part of the body is drilled a blind hole 59 in which is slidably mounted a pusher 60 bearing against the periphery of the extruder member 58 under the action of a spring 61 disposed in the bottom of the hole 59.
  • the sleeve 55 has a slot 62 in which the extruder member 58 can be engaged in order to pivot the latter and to retract it between the faces of the housing 56.
  • edge 63 of the extruder member has a semi-circular shape in cross section.
  • the tool 50 shown in fig. 9 is mounted between the jaws 7 of the mandrel 4, and the turret 11 is in the position shown in broken lines in FIGS. 2 and 5.
  • the tube is engaged between the jaws 12, 13 of the turret and the mandrel 4 is driven in rotation as well as the tool 50, 51.
  • the lever 44 which then acts by the shaft 43 and the pinion meshing with the rack 42, on the carriage 10 and the turret 11 is then actuated manually and the movement of the tube forwards and backwards is communicated to the tube during which said tube is engaged by one of its ends in the space 53 of the calibration tool.
  • the carriage can also be moved back by means of the automatic device via the mother screw 34 and the half-nuts 36, 36a when the lever 41 is acted on.
  • An adjustable stop on one of the two guides of the turret 11 makes it possible to limit the advance and therefore to adjust the length of the calibrated part of the tube.
  • the turret 11 is placed in the position shown in solid lines in FIGS. 2 and 5, and the tube 14 is fixed between the jaws 12, 13 so that the tap is located opposite the bores 19, 20 (fig. 6).
  • a cutter being mounted on the mandrel 4 which is rotated, one proceeds in advance of the carriage 10 and the turret 11 so as to drill a hole in the tube.
  • the cutter is replaced by the extruder tool 54, 58 which is mounted between the jaws 7 of the mandrel 4.
  • the extruder member 58 is retracted into its housing 56 by means of the sleeve 55.
