Definitions

  • the present invention relates to a flare ends of tubes by rolling according to the preamble of claim 1 which is based on document FR-A-2 660 219.
  • connection tight rigid tubes at the different orifices of installation devices is usually performed at using collar fittings.
  • These fittings have a internally shouldered nut and engaged on the tube to connect, at the end of which a collar is fitted.
  • the shouldered nut is mounted captive on the tube and can be screwed onto a threaded end piece orifice of a device.
  • a seal can be placed between the end of the tube and the device to perfect sealing.
  • the collar can for example be brazed on the end of the tube.
  • the collar and the end of the tube must be cleaned. This cleaning increases the time required to making the fitting and making the operation more expensive.
  • the document FR 2 642 500 describes a method of realization of a fitting, according to which the collar of the tube is made by gluing. This process allows make a connection quickly and economically.
  • Document US 3,610,016 describes a machine to flare the end of a tube.
  • This machine presents a base on which are mounted, on the one hand, a fixed assembly comprising two jaws intended for receive the flare tube and on the other hand, a set movable in translation towards the jaws comprising a tool and moved by an attached jack.
  • the tool of this mobile assembly is rotated around an axis parallel to the axis of movement of the assembly mobile and is therefore animated by a cylindrical movement.
  • a motor placed for example under the base of the machine, provides the energy necessary for the proper functioning of this one.
  • the document EP 0 462 719 describes a flare hot tubes.
  • This machine is intended for be used in the field of oil exploration at sea. It has a base formed by two plates end connected by four parallel tubes, one mobile carriage slidingly mounted on the four tubes, one tool driven in rotation about an axis parallel to tubes and mounted on the mobile carriage, means for hold the tube to be flared, as well as means for move the cart.
  • the object of the invention is then to provide a machine for flaring ends of tubes by cold rolling, especially for making fittings with collar, the structure of which is simple, so that this machine can be space-saving and easily transportable.
  • this machine is simple and allows to make a compact machine.
  • the second fixed block incorporates part of the means to bring the snap on the end of the flare tube.
  • this hydraulic cylinder is supplied by a hydraulic pump mounted on the mobile unit.
  • the invention provides a way to achieve using space-saving means.
  • the snap is mounted in a spindle, itself mounted by means of bearings in a support spindle rotated by means training in an orbital movement of the snap, the axis of the head and its pin forming an angle with the axis of rotation of the spindle support, allowing thus to animate the snap of an orbital movement.
  • the snap, the pin and its support are mounted one inside the other.
  • the length of the whole set is then hardly more important than that of the support of brooch.
  • the drive means in a orbital motion of the dowel include a motor whose output shaft, fitted with a pulley, is connected to the spindle support by a belt.
  • the motor can be find above, below or at the height of all to train.
  • the pump hydraulic powering the hydraulic cylinder has a piston on which an eccentric mounted on the end acts the axis of rotation of the spindle support.
  • the spindle holder then activates the pump hydraulic thanks to the eccentric.
  • the means of training in an orbital movement also entail the hydraulic pump and therefore also bring the chuck closer to the end of the tube.
  • One motor can therefore suffice for these two movements.
  • the hydraulic pump supplies the hydraulic cylinder from inside the cylinder piston, we thus finds one after the other, the support of the spindle, the hydraulic pump and the cylinder.
  • the movable block comprises at minus an abutment finger intended to come into abutment at the end of race against a jaw tightening the end of the tube and the machine has a pressure switch connected to the cylinder and controlling a solenoid valve, so that, when the pressure in the cylinder chamber is too high high, the cylinder chamber is connected to a oil tank.
  • the training means allowing to animate the snap of an orbital motion include an electric motor whose power is cut off when the pressure switch actuates the solenoid valve. The machine stops then automatic at the end of the cycle.
  • the invention then also provides a device for connecting the chamber of the cylinder with an oil tank, this device comprising a calibrated valve opening when the pressure in the cylinder chamber exceeds a predetermined value and a drawer one end of which is placed in communication with the cylinder chamber when the valve is open and ordering the opening of a passage between the room of the cylinder and oil tank.
  • the means for guiding the block in translation mobile they advantageously have two columns connecting the two fixed blocks. These two columns allow good guidance and stiffen the whole machine.
  • means to bring the snap on the end of the tube have been described. These means include a hydraulic cylinder. To distance the bolt at the end of the tube, the cylinder described could be replaced by a double-acting cylinder. Preferably, however, the means to distance the snap on the end of the flare tube have compression springs placed between the first fixed block and the mobile unit.
  • the means drive to bring the chuck closer to the end of the flare tube work against springs, and when these means no longer act, the springs move the movable block away from the first fixed block.
  • the jaw holder In order to properly hold the end of the tube at flare, the jaw holder has a tail shape dovetail in which the two jaws of form complementary come to engage, so that, by wedge effect, when the snap rests against the end of the tube, the two jaws tend to move closer to each other, tightening the tube.
  • the first fixed block has a shoe which, side, faces a jaw when the jaws are placed in the jaw holder and on the other hand can to be pushed towards this jaw by an eccentric operated with a lever, to bring the two together jaws of each other and so maintain the end of the tube.
  • the first fixed block comprises a movable stop against which the end of the flare tube to allow proper positioning in the bit and articulated around an axis between a first position where it faces the jaws on the side of the buttonhole and a second position where it is spread so as not to hinder the action of the snap on the end of the tube.
  • the latter comprises a lever
  • the movable unit is equipped with a cam having a surface inclined, cooperating with the lever of the movable stop, of so as to move the stopper into its separated position when the bolt goes towards the first fixed block.
  • the translational movement of the mobile unit can also be used to activate a lubrication.
  • the machine has a sprayer for spraying a lubricant, oriented towards the end of the tube to be flared and actuated mechanically when the movable unit approaches the first fixed block.
  • Figures 1 and 2 show a machine according to the invention in an overview.
  • This machine basically has three parts that can be distinguished well on these two figures: a fixed part before 1, a rear fixed part 2 and a mobile part 3 located between these two fixed parts 1,2.
  • the front fixed part 1 essentially serves to position and hold in place the end of a tube 4 to be flared, and possibly a socket shouldered 5. For this purpose, it constitutes a jaw holder in which two jaws can take place 6.
  • This jaw 6 has the shape of substantially a parallelepiped of which one face 7 is inclined.
  • the jaw holder has a tail shape dovetail.
  • the inclined face 7 of each jaw comes then against an inclined face of the jaw holder.
  • the face of each jaw 6 in contact with the other jaw has a recess intended to receive the socket 5 and the end of the tube 4. On its part intended to receive the tube, this recess is covered with carbide so to obtain a better coefficient of friction allowing thus better maintain the end of the tube 4 in position.
  • the widest side of the dovetail is located at the end of the tube 4 to be flared. So when a tool acts on this end to flare the tube, he pushes the jaws 6 and by corner effect, these tighten so that they better hold the end of the tube 4.
  • the front fixed part 1 is provided with a stop 8 mobile, articulated around an axis of rotation.
  • the stop 8 is placed facing the recess made in the jaws 6 for receive the end of the tube 4. The latter is then slipped between the two jaws 6 which are not tight until it comes into abutment against the movable stop 8.
  • a pre-locking device is fitted to the front unit 1 of the machine. It has a shoe 9 which, on one side, faces a jaw 6 placed in the jaw holder and, on the other hand, can be pushed towards this jaw 6 by an eccentric 10 actuated using a lever 11. When the lever 11 is actuated to push the shoe 9, the jaw 6 pushed closer to the other jaw 6, thus allowing the end of the tube 4 to be clamped in the bit.
  • the front fixed part 1 described above is connected to the rear fixed part 2 by two columns 12 parallel which serve as a guide in translation to the part mobile 3.
  • the mobile part 3 is mounted via four bearings 13 on the two columns 12 connecting the fixed blocks front 1 and rear 2. It includes a flange 14 which constitutes the tool used for flaring the end of the tube 4, a pin 15 in which is mounted the bolt 14, a spindle support 16 and a electric motor 17 driving the spindle support 16 rotation via a belt 18 and a pulley 19 mounted on the motor output shaft 17.
  • the spindle support 16 is mounted in a housing 20 by means of ball bearings 21.
  • the axis of this support 16 is parallel to the columns 12 and therefore to the direction of movement of the movable block 3.
  • the spindle support 16 On the side facing the jaw holder, the spindle support 16 has a recess serving as a housing for pin 15. This last is mounted via a socket needles 22 and a thrust ball bearing 23 in the recess of the spindle holder.
  • the spindle axis 15 mounted in its support 16 is inclined a few degrees relative to to the axis of the spindle support 16.
  • the dowel 14 is housed in the spindle 15, parallel to the axis of spindle 15. It is therefore inclined relative to the axis of the spindle support 16.
  • the electric motor 17 is mounted parallel to the axis of the spindle support 16 on the housing 20.
  • the belt 18 drives the spindle support 16 in rotation and thanks to the inclination of the axis of the dowel 14 and from its spindle 15, the snap 14 is driven by a orbital motion.
  • a cover closes the housing 20, which serves support for a hydraulic pump 25.
  • the latter comprises a piston 26, an inlet valve 27 and a outlet valve 28.
  • the piston 26 is driven in a going movement and comes by an eccentric 29 mounted on the support of spindle 16 opposite to the dowel 14 and housed in a recess made in the cover 24.
  • the pump 25 is supplied with oil by a pipe hose 30 connected to an oil tank 31. The latter takes place in the rear fixed part 2 of the machine.
  • This pump 25 supplies a hydraulic cylinder.
  • the body of this cylinder is integrated into the rear fixed block 2, the chamber of this cylinder is constituted by a blind bore 32 made in the rear block 2 and the piston 33 of this cylinder is integral with the cover 24 of the housing 20.
  • the oil supply to the cylinder is through a channel 34 drilled in the cover 24 and the piston 33 and connecting the pump outlet to the cylinder chamber.
  • the machine stops automatically and is described below.
  • the movable block 3 On the side of the bolt 14, the movable block 3 has two fingers 35 serving as mechanical stops. Each jaw 6 has a milled surface 36 making facing a finger 35. This surface 36 is placed in such a way so that a finger 35 abuts against it when the end of the tube 4 is flared.
  • springs 39 arranged between the front fixed block 1 and the movable part 3 surround the two columns 12.
  • two spacers 40 arranged around the springs 39 are provided to limit the travel of the moving part. So, if the motor 17 is started inadvertently then there is no jaw 6 in the jaw holder, the movable block 3 abuts with spacers 40 and the pressure switch 37 controls the return of the mobile part 3.
  • the pressure switch 37 can control not only the solenoid valve 38, but also the supply of the motor 17. So when the pressure becomes too great, the engine 17 is stopped.
  • FIG. 3 shows in section a valve 41 having functions similar to those of pressure switch 37 and the solenoid valve 38.
  • This valve 41 is connected by its input 42 to the chamber 32 of the jack and via its outlet 47 to the reservoir 31. It includes a calibrated valve 43 and a drawer 44.
  • the calibrated valve 43 opens and puts the cylinder chamber in connection with a chamber 46 located at one end of drawer 44. The latter is then pushed under the pressure and slides into a position where the inlet 42 is linked to the outlet 47, that is to say that the chamber 32 of the jack is connected to the tank 31.
  • a latching system comprising a ball 48, a spring 49 and a notch 50 produced on a rod 51 integral with the drawer 44 is provided.
  • This valve 41 can in particular be used when the machine described above is placed in a dangerous atmosphere with risk of explosion. Engine electric 17 is then replaced by a pneumatic motor for example and the machine can operate without doing spark.
  • Figure 4 shows a device for automatically raise the movable stop 8 necessary to the positioning of the end of the tube 4 when the block mobile 3 approaches the front fixed part 1.
  • the device comprises a lifting cam 52 mounted on the movable block 3.
  • This cam 52 has a inclined surface which cooperates with a lever integral with the movable stop 8, so that when the block mobile 3 advances towards the front fixed part 1, the stop mobile 3 deviates from the position where it allows the correct positioning of the end of the tube 4.
