Definitions

  • the invention relates to a crimping device for fixing a base and / or a cover with an annular rim in the end of a hollow metallic tubular body, made of plastic or composite material.
  • the crimping is carried out vertically and, in general, from the bottom to the top. Therefore, it is necessary to exert on the hollow tubular body a thrust directed in the opposite direction. This can only be exerted from above the hollow tubular body. Not only is there a risk of compaction of this body, but it is also possible to crimp only containers whose height of the hollow tubular body corresponds to the passage height located between the crimping tool and the means pressing on the above the body in question.
  • the present invention aims to remedy these drawbacks.
  • the invention as characterized in the claims, solves the problem of creating a crimping device allowing, on the one hand, the fixing of a bottom and / or a cover on a hollow tubular body without deformation of the latter, and, on the other hand, to remove all the means pressing on the top of the body as currently known.
  • the telescopic means exert a lateral thrust from the center towards the outside and cooperate with a belt coating the outer periphery of the hollow tubular body.
  • the telescopic means exert a lateral thrust from the outside towards the center and cooperate with a belt on which is applied the internal face of the annular rim of the bottom and / or of the cover capped by the end of the hollow tubular body.
  • the crimping device 5 comprises a central cylinder 6 or any other pushing device whose piston 7 is integral with the lower end 8 of an axis 9 sliding vertically.
  • This axis 9 moves in bearings 10, 11 housed in a bearing 12 integral with a seat 13.
  • the latter is fixed by small columns 14, 15, 16,17 has the flange 18 of the central cylinder 6 or any other pushing device.
  • the axis 9 has at its upper end 19 a recess 20 making it possible to obtain a shoulder 21 on which is threaded a sole 22 made integral with said axis 9 by any means.
  • a sole 22 To this sole 22 is fixed the base 23 of a crimping tool 24.
  • a compressible material 27 serving as a shock absorbing pad is interposed between the top 25 of the sole 22 and the bottom 26 of the base 23.
  • l crimping tool 24 On its upper periphery 33, l crimping tool 24 has a beveled edge 34 on which the edge 35 of the lower end 1 of the hollow tubular body 2 slides.
  • This beveled edge 34 leads to a forming cup 36 which gives the lower end 1 of the tubular body hollow 2, the crimping bead 37 preventing the cover or the bottom 3 from leaving the hollow tubular body 2.
  • the perimeters of the vertical jacket 30, of the crimping tool 24 and of the central block 42 are adapted to the section of the hollow tubular body 2, the latter possibly being round, oval or polygonal.
  • the holding in place of said lower end 1 is done by peripheral pinching between the vertical jacket 30 and the central block 42.
  • the lower end 1 of the tubular body 2 and especially to remove the crimped container it is necessary to provide sufficient space between the outer periphery 43 of the central block 42 and a belt 55 secured to the inner periphery 44 of the vertical jacket 30 to allow easy passage of the crimping bead 37 .
  • the invention provides telescopic means 45 ensuring, on the one hand, a sufficiently significant pinching of the lower end 1 of the corpstubular 2 in the crimping phase and, on the other hand, sufficient space for the passage of the crimping bead 37.
  • Two embodiments can be recommended, either the telescopic means 45 protrude relative to the outer periphery 43 of the central block 42 for crimping and retract inside the central block 42 for positioning from the lower end 1 of the hollow tubular body 2 and for the withdrawal of the crimped container, or the telescopic means 45 are an integral part of the vertical jacket.
  • the telescopic means 45 are a plurality of jacks 46, 47, 48, 49 of which the piston 50, 51, 52, 53 cooperates with the internal face 54 of the annular rim 4 of the cover or of the bottom 3 in exerting a lateral thrust on this annular rim 4, thrust transmitted to the lower end 1 of the tubular body 2 so that the latter is applied against the belt 55 secured to the inner periphery 44 of the vertical jacket 30.
  • Cooperation between the pistons 50, 51, 52, 53 and the belt 55 ensures the pinching described above, the force of this pinching being predetermined and a function of the lateral thrust exerted by said pistons 50, 51, 52, 53.
  • the different jacks 46, 47 , 48, 49 are distributed over the entire perimeter of the central block 42.
  • each of the pistons 50, 51, 52, 53 has at their ends either straight or curvilinear segments adapted to the section of the hollow tubular body 2, these segments bearing against the annular rim 4. Therefore, increases the pressure zone while decreasing the number of telescopic means 45.
  • the pistons 50, 51, 52, 53 are interconnected by said segments.
  • the pistons 50, 51, 52, 53 are interconnected by said segments.
  • the compression chamber 65 is connected to a first supply of air or pressurized liquid 67 via a hole 68 opening, on the one hand, into said compression 65 and, on the other hand, in an annular chamber 69, an orifice 70 produced in the central block 42 opening into the annular chamber 69 and located in alignment with a bore 71 made in one of the uprights 40 and to which said supply 67 is connected.
  • the second compression chamber 66 is connected to a second supply of air or pressurized liquid 72 via a hole 73, a second annular chamber 74, an orifice 75 and a bore 76 parallel to the bore 71.
  • the piston 50, 51, 52, 53 is caused to advance while supplying pressurized fluid to the first compression chamber 65 , on the one hand, the piston 50, 51, 52, 53 recedes and, on the other hand, the discharge of the fluid contained in the second compression chamber 66.
  • the telescopic means 45 are not necessarily pneumatic or hydraulic means. Indeed, these means can be mechanical means. For example, instead of a piston, sliding rods actuated by a set of connecting rods and camshafts are used. Alternatively, threaded rods actuated by a motor element and cooperating with tapped holes made in the central block 42 are used.
  • the different telescopic means ques 45 are an integral part with the vertical jacket 30.
  • the telescopic means 45 exerting a pressure directed from the outside towards the center on the outer periphery 77 of the lower end 1 of the hollow tubular body 2, pressure transmitted to the annular rim 4 of the cover or bottom 3 apply the internal face 54 of the latter and the lower end 1 of the hollow tubular body against a belt secured to the central block 42.
