Definitions

  • the present invention relates to a method for manufacturing guns for spraying liquid at very high pressure and in particular guns for machines to work parts by jet of liquid at very high pressure including cutting and / or machining machines. It extends to projection guns made according to this manufacturing process
  • the technique of cutting and / or machining by high-pressure liquid jet is to project liquid under a pressure of 1000 to 8000 bar.
  • the liquid usually pure water or with additives, is then expelled at a very high speed, from 600 to more than 1000m / s, and directed against the workpiece.
  • the technique of waterjet machining very high pressure can work many materials such as plastics, paper or metal alloys and without dust emission or heat generation.
  • abrasive particles can be added to the projected water.
  • the cutting heads used according to this cutting method conventionally comprise a collimation tube, a nozzle of small internal diameter, a mixing chamber, and a liquid projection gun at very high pressure.
  • the liquid under very high pressure enters through the collimation tube.
  • the liquid is then thrown through the nozzle and returns to high speed in the mixing chamber provided with an inlet of abrasive particles.
  • the mixture of liquid and abrasive particles is concentrated and the jet under very high pressure is directed on the workpiece by a small bore inner barrel.
  • This gun is known generally as the focusing gun.
  • these focusing guns are pieces having a ratio length to large diameter which makes difficult the machining of a conduit from a massive piece.
  • machining does not allow to go below a certain threshold of internal diameter for a given length.
  • the internal diameter of the focusing gun determines the accuracy of the jet of liquid.
  • the focusing guns are usually made of tungsten carbide. Indeed, the implementation of this ceramic is easy and a reasonable cost for such an application.
  • tungsten carbide guns can only be used with oxide abrasives such as garnet or alumina oxide of relatively low hardness. Indeed, the use of abrasives with a hardness higher than that of tungsten carbide, from 8 to 9 on the MOHS scale, would quickly wear inside the barrel resulting in a premature loss of precision and a duration of life incompatible with the usual applications of very high pressure liquid jet machining machines.
  • Another method of manufacturing focusing guns is to deposit a vapor phase ceramic on a cylindrical graphite support and then to remove the cylindrical support by heating once the ceramic has formed a tubular structure around the graphite.
  • This process makes it possible in particular to manufacture silicon carbide guns, a ceramic of high hardness, of the order of 9.5 on the MOHS scale, making it possible to work with a wide range of abrasives that are no longer limited to to oxides.
  • a focusing gun In order to circumvent problems related to the ratio length to internal diameter of the barrel, it has been envisaged to manufacture a focusing gun by assembling several elements. These elements may be cylindrical parts of low height, and therefore of low length to internal diameter, which are aligned along the axis of the barrel conduit and held together by clamping with an outer piece-type sheath. This technique is however hardly exploited. Indeed, it does not allow to properly align the different elements of the barrel, and differences in alignment cause disturbances of the flow of the liquid at very high pressure. In addition, the junction areas are particularly sensitive to wear.
  • the present invention aims at overcoming the various drawbacks of the current techniques for manufacturing focusing guns and has the following main objective of providing a simple implementation method and a low cost, to control very precisely the shape and dimensions of the projection pipe of the focusing gun.
  • Another object of the invention is to provide a method for the manufacture of focusing guns by means of any type of material, and in particular of very high hardness materials such as silicon carbide ceramics.
  • Another object of the invention is to provide a method for the manufacture of focusing guns compatible with a wide range of abrasives and having an increased lifetime regardless of the nature of the abrasive used.
  • the focusing gun is constituted of two parts secured to one another by gluing, the relative prior positioning of the parts is ensured by means of at least one centering rib and a cavity of centering which are designed to cooperate, to ensure the accuracy of the relative positioning, before the surfaces to be secured by gluing do not come into contact with each other.
  • the two pieces are perfectly guided and can in no way undergo any transverse relative displacement likely to alter their centering.
  • the two parts are directly in contact with one another at the level of the plane median zones which make it possible to separate the bonding zone and the conduit of the focusing gun, and therefore lead to secure against a transfer of adhesive substance towards the said conduit.
  • each reservoir formed in the assembly face of a workpiece a centering rib of length at least equal to that of said bonding reservoir, interposed between the latter and the central groove in said assembly face, so that each rib thus has the dual function of centering element and protective barrier of the focus gun duct.
  • this protective barrier not only preserves the integrity of the conduit of the focusing gun, but also leads to prohibit any migration of the adhesive substance towards the plane central zone, so that the two parts come into contact with one another via "unpolluted" faces.
  • the contact between the two pieces thus consists of a direct contact, without significant play.
  • this game is much less than the diameter of the abrasive particles, so that the latter can not lodge in the gap between the parts and wear prematurely the focusing gun.
  • each tank formed in the assembly face of a room is associated with a so-called overflow space communicating with said tank for the reception of the tank. possible excess of adhesive substance during the assembly of the two parts, each of said overflow spaces being arranged laterally opposite the plane central zone relative to the associated reservoir.
  • each overflow space consists of a slot extending from the periphery of the focusing gun, in the assembled position of the two parts, arranged between the said assembly faces facing each bonding tank.
  • Such an overflow space allows, in addition to the absorption of an excess of adhesive surface, to distribute this excess between the assembly faces of the two contiguous pieces and thus increase the bonded surface of these assembly faces.
  • the other piece has an assembly face comprising a flat area, called bonding, coplanar with the central zone plane, adapted to extend opposite the associated bonding reservoir and seal the latter.
  • a focusing gun is produced from two identical parts each comprising at least one centering assembly consisting of a centering rib and a centering cavity arranged symmetrically. on either side of the central groove.
  • centering ribs are formed and centering cavities extending along the majority of the parts are housed.
  • the assembly faces of the parts are cleaned before the deposit of an adhesive substance.
  • the step of depositing an adhesive substance is advantageously preceded by a step of improving the adhesion of each reservoir and each bonding zone, such as erosion step by a laser attack, an acid or plasma or deposition step of a preparation layer, in particular based on silane.
  • the step of bonding the parts with an adhesive substance is advantageously followed by a machining step of the focusing gun.
  • an adhesive substance advantageously chosen from epoxides, methacrylates, polyimides or a mixture thereof is advantageously used.
  • parts of a material with a hardness greater than 8 on the MOHS scale are advantageously used, such as, for example, advantageously silicon carbide.
  • the invention also extends to a focusing gun comprising alone or in combination, any of the features set forth in the claims or the description of the present application.
  • the focusing gun shown in the figures is intended, in the usual way, to be mounted on a cutting head of a liquid projection machine at very high pressure.

  • this part 2 are determined according to the dimensions of the focusing gun 1 to be produced.
  • These parts 2 are, in addition, made of a material of high hardness, preferably with a hardness greater than 8 on the MOHS scale, in order to make it possible to work with materials of a hardness superior to the materials usually worked. with tungsten carbide guns.
  • these parts 2 may in particular be made of silicon carbide.
  • each part 2 comprises, formed in the junction face J, and centered on the longitudinal plane of symmetry (S) of said piece, a central groove 3 of semi-cylindrical section adapted to form a cylindrical duct 12 in the assembled state of two pieces 2.
  • This central groove 3 extends over the entire part 2 and comprises, at the proximal end of this piece, a flared semi-conical section 3a for introduction into the conduit 12 of the liquid under pressure.
  • central grooves 3 may be of shapes other than semi-cylindrical, and form ducts 12 of all sections, parallelepipedic ...
  • a duct 12 of parallelepipedal shape may be chosen for applications consisting of to give a sweeping motion to the jet of liquid.
  • This additional material is preferably of greater hardness than the pieces 2 and can for example consist of diamond. This material may, in particular, be added by vapor deposition.
  • each piece 2 has a plane central zone 4, 5 divided into two half-zones 4, 5 respectively extending on either side of the central groove 3.
  • This central zone 4, 5 is , in addition coplanar with the diametral plane (P), so that the median areas of two pieces 2 assembled are in contact with each other.
  • this median zone 4, 5 is bordered by a centering rib 6 of rectangular parallelepipedal section protruding from the assembly face J.
  • this central zone 4, 5 is itself bordered by a centering groove 7 with a cross-section of that of the centering rib 6, the said centering rib and the said centering groove being arranged symmetrically with on both sides of the plane of symmetry (S) so that, as shown in Figures 3 and 4 , the centering rib 6 of each piece 2, 2 'comes to be housed in the centering groove 7 of the other piece 2', 2 during assembly of said pieces.
  • each part 2 forms, between the centering groove 7 and the corresponding longitudinal edge of said part, a flat lateral zone 8 extending in the diametral plane (P) and thus coplanar with the median flat area 4, 5.
  • This assembly face J further comprises, laterally contiguous to the centering rib 6 and separated from the central zone 4, 5 by said centering rib, a longitudinal groove 9 intended to form a reservoir for an adhesive substance 11, and to be closed, in the assembled position of two pieces 2, 2 'and as shown in FIG. figure 4 , by the lateral zone 8 of the part 2 vis-à-vis.
  • each of the grooves 7 and 9 and ribs 6 extend longitudinally from the distal end of each piece 2, substantially over three quarters of the length of said piece.
  • each part 2 finally forms, between the reservoir 9 and the corresponding longitudinal edge of said part, a flat lateral zone 10 extending substantially back from the diametral plane (P), so that the zone lateral 10 of a part 2 delimits a slot opening laterally at one of the generatrices of the focusing gun 1, with the lateral face 8 vis-à-vis the second part 2 'forming said said focusing gun.
  • This slot 8-10 thus forms a duct for evacuating the possible excess of adhesive substance and distributing this excess between the faces.
  • assembly J two pieces 2, 2 'assembled, thereby increasing the bonded surface of these assembly faces.
  • the figure 5 represents an alternative embodiment according to which the plane lateral zone bordering the reservoir 9 consists of a plane face delimiting an obtuse angle of the order of 120 degrees with the diametral plane (P).
  • the lateral zone 8 bordering the centering groove 7 forms a dihedron with an apex angle of the order of 120 degrees, one of the two half-planes 23 of which is adapted to extend parallel to the plane face 25, and to delimit with the latter a volume of retention of the excess of adhesive substance, closed at the periphery of the focusing gun 1, by a longitudinal edge 24 projecting from said half-plane 23.
