Definitions

  • the present invention relates to a shot blasting installation, in particular for parts of any shape by means of an adjustable lance.
  • the frame carrying the support is in turn joined on its lateral sides to two other flexible curtains which roll up and also take place on axes, this time vertical, provided on the sides of the opening and which allow movement transverse of the chassis and consequently of the support which is associated therewith.
  • these movements in perpendicular directions, it is thus possible to bring the projection lance into any position in front of the opening of the enclosure.
  • these installations have the drawback of requiring flexible curtains which can be rolled up or unwound on axes depending on the positions of the lance support.
  • a shot blasting installation comprising a nacelle capable of receiving an operator and on which is mounted an adjustable lance capable of projecting a shot of shot, the operator being protected by a vertical wall pierced with a glass opening allowing you to check the work done.
  • the nacelle can be moved vertically on a support frame, while the projection lance is slidably mounted axially through the vertical wall of the nacelle, while being capable of being articulated thereon by means of a ball joint, an adjustable nozzle. being also provided at the end of this lance.
  • the parts to be shot-blasted are generally placed on a carriage in order to make them scroll over the entire length in the area swept by the spray lance. But under these conditions, the length of the parts to be treated must however be less than half the length of the blasting booth, while the arrangement of the parts to be shot blasted on a carriage implies ensuring a perfect wedging of these parts on it. However, these provisions raise difficulties, particularly in the case where the parts to be shot-blasted have a complex shape.
  • the present invention relates to a shot blasting installation of the type generally recalled above but designed so as to significantly increase the length of the scanning area of the spray lance in order to be able to clean relatively long parts without having to move on a cart.
  • the invention also aims to minimize the footprint of the installation.
  • the installation according to the invention for the shot peening of parts of any shape inside an enclosure by means of a mobile lance for projecting shot, mounted on a nacelle capable of receiving an operator and which is vertically movable on a frame, in which this frame is mounted movable in one direction or the other under the effect of a drive device along a first horizontal guide path, is characterized in that, on either side of the frame, two curtain walls with a metal structure are provided attached to the frame along their vertical sides also mounted movable along a second horizontal guide path, parallel to the first.
  • the two curtain walls are articulated so as to be able to curl, their guide path extending, in one direction or the other, beyond the ends of the guide path of the frame.
  • this lance is orientable by articulation in a ball joint carried by this wall, that it can slide axially through the latter and that it is also capable of turning on itself.
  • this lance carries at the end a projection nozzle 6 which is articulated as described in the main patent.
  • the nacelle 1 can slide vertically between the uprights 7 of the frame 2 and is suspended from a curtain 8 attached to a winding drum 9 whose shaft can be driven by a motor 10.
  • This curtain also extends below the nacelle 1 to close the space left free by the latter when it is in the raised position, the lower end of this curtain being wound on another drum provided at the base. of the frame 2.
  • the vertical wall 4 of the nacelle has an opening provided with a window 11 making it possible to control the orientation of the terminal nozzle of the lance and to monitor the working conditions.
  • the external face of this window is protected from shot rebounds by a turbine 12.
  • the vertical frame 2 is mounted movable along a horizontal guide path and comprises, on either side, two curtain walls designated by the general reference 13, these being attached to the corresponding vertical sides of this frame and also mounted movable along a horizontal guide path.
  • the vertical frame 2 is suspended from a horizontal beam 14 on which it is supported by means of two rollers 15, one of which can be driven in rotation by a motor 16 to serve as a means of driving this frame, in one direction or in the other, along the beam 14.
  • the latter is carried by uprights 17 bearing on the ground and which may be part of the chassis of this installation.
  • the frame 2 is supported on a guide profile 18 which can also form part of the frame of the assembly. This support is carried out by means of rollers 19.
  • the two curtain walls 13 are suspended from a horizontal rail 20 disposed at the level of the beam 14 and parallel thereto.
  • this rail is fixed to this beam by means of supports 21.
  • the ends 22 of this rail extend beyond the beam 14 and are bent inwards, as shown in FIG. 1 , so as to each constitute a kind of siding for the respective end of the corresponding curtain wall 13.
  • the ends of this rail are fixed on support arms 23 themselves carried by the beam 14.
  • the two curtain walls are engaged in a horizontal slide 24 which has the same shape as the upper rail 20.
  • Each of these curtain walls is constituted by a series of relatively narrow panels 25, arranged one after the other and which are articulated with one another along vertical axes.
  • each of the panels 25 is constituted by a closed metal box 26, on the inside, by a cladding plate 27 and which encloses a lining 28 for soundproofing.
  • the external face of each of these panels that is to say that facing the direction of projection of the shot, carries a shielding plate 29 intended to protect it from shot rebounds.
  • a joint cover 30 is also disposed on the external side at the location of the joint existing between two successive panels 25.
  • Each of these joints is made of elastic material and comprises, on the internal side, a tongue 31 fixed on the edge of one corresponding panels.
  • the plaques interior 27 have, on their vertical sides, flanges 32 and 33 nested one inside the other. The profile of these edges is such that they ensure the tightness of the corresponding curtain wall against a risk of passage of shot rebounds, while allowing the articulation of the panels with respect to each other for the curtain walls.
  • junction hinges 34a, 34b and 34c distributed over the height of the panels, for example three.
  • the axes 35 of the hinges 34a provided at the upper part, serve to ensure the suspension of the two curtain walls 13. Indeed, on each of these axes is articulated a yoke 36 carrying a roller 37 bearing on the rail 20 of suspension.
  • axis 38 of the hinges 34c As for the axis 38 of the hinges 34c, provided at the lower part, it extends downwards by a part carrying a roller 39 engaged inside the lower guide slide 24 (see FIG. 3).
  • the two curtain walls 13 are attached to the corresponding vertical uprights 7 of the frame 2 by means of two panels 40 which may have a structure similar to that of the panels 25.
  • these two curtain walls form, with the frame 2, an assembly which can be moved in one piece in the horizontal direction by sliding along the beam 14 and along the rail 20. This translational movement is controlled by the operator by operating the motor 16 in one direction or in the other. In such a case, one of the curtain walls is pushed by the frame 2, while the other is pulled by it.
  • the frame 2 can then be moved from one of the ends of the beam 14 to the other, between position 2a drawn in phantom on the left side of FIG. 1 and the symmetrical position on the right.
  • the curtain wall 13 located on the side of the end near which the frame 2 is placed, is wound on the corresponding curved end 22 of the rail 20 as well as on the respective end of the slide 24.
  • this is the case for the right curtain wall.
  • the curved ends of the rail 20 of the slide 24 constitute in some ways garage tracks reducing the size of the entire installation in the direction of the length.
  • the length of the curtain walls 13 obviously depends on the total length provided for the installation.
  • the upper rail 10 and the lower slide 14 therefore extend, beyond the ends of the beam 14, by curved portions whose length may be more or less important depending on the case.
  • the corresponding ends of this rail and this slide can be simply bent as provided in the attached drawing or be wound in a spiral to allow the curtain walls to be wound on themselves.
  • these curved ends can also constitute a sort of return path for the curtain walls, behind the zone of movement of the nacelle 1.
  • the translation of the assembly constituted by the frame 2 and the two curtain walls is controlled by the motor 16.
  • one or more additional motors can be provided to drive the curtain walls themselves.
  • the main advantage of the installation according to the invention lies in the fact that the mobile nacelle 1 carrying the projection lance can be moved not only in the vertical direction, but also in the horizontal direction. Under these conditions, this lance can sweep a very long zone corresponding to the length of the parts to be treated, which avoids the need to arrange these on carriages to make them pass in front of the projection lance.
  • the length of the installation can be more or less important depending on the length of the parts to be treated.
  • the installation according to the invention is not limited to the single embodiment described above because it is simply an example.
  • the curtain walls 13 could consist of continuous flexible elements comprising an abrasion-resistant surface on the side facing the blasting booth.
  • the installation chassis could be produced differently.
  • the mobile frame 2 instead of being suspended from a horizontal beam, the mobile frame 2 could rest on the ground by being mounted mobile on one or more guide rails.
