Definitions

  • the present invention relates to a machine for recharging mechanical parts by the "plasma” process, therefore using an arc formed by an ionized gas column.
  • Machines of this kind are already known, which in all cases include a torch and a powder distributor supplying said torch.
  • current reloading machines have, in operation, limited performances, which the present invention proposes to improve. , in particular in the following aspects: saving powder, controlling the dilution rate, increasing the deposit rate (in welded reloading), positioning and mobility of the torch, ease of control and maneuvering, both for the dispenser powder and for the torch, so as to produce a rational and efficient machine.
  • the invention also aims to provide a universal machine, allowing recharging by projection. tion, as well as welded reloading, and programmable in pre- and post-welding.
  • the machine according to the invention for reloading mechanical parts by the "plasma” process of the type comprising a torch and a powder distributor, with a rotating disc with a vertical axis and a scraper, feeding said torch, is essentially characterized by the fact that the powder distributor comprises at least one gas injector, disposed below the periphery of the rotary disc, and having its outlet connected, by a direct conduit, to the torch.
  • This injector allows the powder to be sucked in and conveyed under pressure, by a "carrier” gas, to the torch, avoiding any clogging of the conduits by the very dense powder.
  • a "carrier" gas e.g., a "carrier" gas
  • two gas injectors are arranged, diametrically opposite, below the periphery of the same rotating disc, associated with two scrapers and receiving the powder by two symmetrical funnel-shaped holes, each of the two injectors having its outlet connected, by a corresponding conduit, to the torch-
  • a drawer is provided, which can be moved horizontally. so that one of the two funnel-shaped holes can be closed in one position when you want to use a torch with a single powder supply.
  • a guide sleeve, rubbing on the upper face of the disc is freely mounted in the cylindrical lower part of each funnel-shaped hole .
  • each of them comprises in particular a receiver, in the form of a funnel, surmounting a diffuser, as well as a lateral gas inlet, the conformation of the diffuser being such that a gas vortex is created, into which the powder is sprayed.
  • each injector is further connected by a channel to the chamber containing the rotary disc.
  • the supply of powder is ensured, according to another characteristic, by means of two jars disposed above a body forming a collector, which surmounts the part containing the rotary disc, a drawer which can be moved horizontally in said body making it possible to put into service. either of the two jars of powder.
  • These provisions allow alternative use and filling of the two jars, which can be facilitated by providing, at the base of each jar, a level control means (magnetic detector).
  • the device can even be further improved, by slaving the operation of the drawer to the level detection signal, and / or by providing for the automatic stopping of the machine if the control means detect an absence of powder simultaneously in the two jars.
  • the torch supplied from the powder distributor by flexible conduits, is supported by a mobile assembly, comprising a horizontal translation control and a vertical translation control.
  • This mechanical assembly preferably remotely controlled, gives an exact position of the torch in the longitudinal position and in height, without the need for adjustments on the machine itself.
  • the horizontal translation control itself comprises, in addition to the means making it possible to position the torch longitudinally, other means which make it possible to control, in an adjustable manner, an oscillation of the torch.
  • the motors used will be, in particular, electric stepper motors, allowing centralized digital control of the movements of the torch.
  • the control screws may be, in whole or in part, ball screws.
  • the machine generally comprises a fixed support 1, above which is mounted a fixed powder distributor 2, the support 1 also serving as a guide for a mobile assembly 3 supporting the torch 4 , the latter being supplied from the distributor 2 by two flexible conduits 5 and 6.
  • the powder distributor 2, fixed above the support 1 by means of a vertical plate 7, is shown in detail in Figures 3 to 6.
  • This distributor comprises a body, formed by an upper element 8 and a lower element 9, between which is slidably mounted, in a horizontal direction, a first drawer 10.
  • the upper element 8, having two symmetrical recesses 11, serves as support for two jars 12 made of transparent material, each jar 12 surmounting one of the recesses 11 and being closed at its top by a removable cover 13.
  • the lower element 9 has a central opening 14 in the form of a funnel.
  • the slide 10 guided in sliding and stopped by a finger 15 engaged in a groove, has a hole 16 making it possible to communicate one or the other of the two recesses 11 with the opening 14 located below.
  • a sub-assembly consisting of an upper plate 17 and a lower plate 18, between which is interposed a ferrule 19 made of transparent material.
  • the lower plate 18 comprises two diametrically opposite housings 30, located below the periphery disc 22, which receive two respective injectors 31, the details of which are clearly visible in FIGS. 5 and 6.
  • Each injector 31, of vertical axis comprises a diffuser 32 surmounted by a receiver 33, these two parts being mounted in the corresponding housing 30, with interposition of respective O-rings 34 and 35, and being retained in said housing 30 by a circlip 36.
  • a nozzle 37 fixed on the side of the plate 18, constitutes a lateral inlet of carrier gas, which is distributed by means of the diffuser 32 whose particular conformation, with openings 38 offset radially, appears on the Figure 6.
  • a bent channel 39 hollowed out in the plate 18, further communicates the chamber containing the rotating disc 22 with the annular space which, through the aforementioned openings 38, communicates with the interior of the injector.
  • an outlet stub 4 At the base of each injector 31 in the diffuser 32, there is mounted an outlet stub 4 0, to which is connected one of the flexible ducts 5 and 6 leading to the torch 4.
  • the powder dispenser 2 described above, operates as follows
  • the powder supply is ensured by means of a single jar 12, or by means of two jars 12, used alternately.
  • a level 41 control means provided on element 8 at the base. of each jar 12, emits a signal announcing that this jar is almost empty.
  • the first drawer 10 is then moved. so as to put the other jar 12 in service, and proceed to fill the jar which has just been emptied and so on.
  • the powder reaches, by gravity and sliding, in the central opening 14. From there, it falls either simultaneously in the two holes 20, or in only one of these holes 20, depending on the position of the second drawer 21. In fact, one of the holes 20 is closed by means of this drawer 21 only when one wants to use a torch 4 with a single supply powder.
  • the latter reaches the disc 22, driven in rotation, preferably at adjustable speed, from the gear motor 24
  • the powder is thus driven in rotation with the disc 22 and, meeting the scrapers 27, it is moved outwards and falls from the disc 22 into the receivers 33, in the form of funnels, from the injectors 31. is thus projected at the center of each injector, where it is sucked in by the gas stream, which forms a vortex taking into account the particular conformation of the diffuser 32 with its openings 38 (see FIG. 6), the channel 39 allowing the pressures.
  • the powder is conveyed under pressure by the gas, through the conduits 5 and 6, to the torch 4, produced according to a known principle and not forming the subject of the present invention.
  • This torch 4 is mounted, held by a support 42, on the mobile assembly 3 already mentioned, which generally comprises a horizontal translation control 43 and a vertical translation control 44, making it possible to move the torch 4 horizontally (arrow 45 ) and vertically (arrow 46) - see Figures 1 and 2 .
  • This device comprises a first subset of mobile, consisting of two pairs of parallel guide bars and horizontal, respectively 47 and 4 8, whose ends are fixed to two flanges 49 and 50, one of these flanges 49 on the control horizontal translation 43.
  • the first two guide bars 47 of this mobile sub-assembly are slidably mounted, by means of ball bushings 51, on the fixed support 1 which they pass through horizontally.
  • a control screw 54 driven in rotation by a motor 55, forming part of the horizontal translation control 43.
  • This screw 54 cooperates with a complementary element 56 mounted on the fixed support 1; it can be an ordinary screw or a ball screw.
  • the screw 54 is protected by two bellows 57 and 58, arranged between the flanges 49 and 50, on either side of the fixed support 1.
  • a carriage 60 On the other two guide bars 48 of the mobile sub-assembly under consideration, is slidably mounted, by means of ball bushings 59 (see FIG. 10), a carriage 60. Between the two guide bars 48 is rotatably mounted, in bearings 61 and 62 carried by the flanges 49 and 50, a control screw 63. The latter is rotated from a motor 64, forming part of the horizontal translation control 43, this by means of pinions 65 and 66 (see also figure 8). The screw 63 cooperates with a complementary element 67 mounted on the carriage 60. Preferably, it is a ball screw, and this is protected by two bellows 68 and 69, arranged between the flanges 49 and 50, on either side of the carriage 60.
