Definitions

  • the present invention relates to a punching method, and more particularly to a method of punching at least one orifice in a wall of a frame framing section comprising a filler panel, for example a glazing unit, said section being formed of two generally planar sections parallel to each other connected by at least two connecting bars so as to form a closed cross section profile, said wall constituting one of said two sections.
  • Such frames and their filler panel, in particular glazing, associated respective forming sets such as doors or windows, are used in the field of construction, in particular to ensure the closure of a closed interior space vis-à-vis from the outside.
  • thermal break frames For example known so-called "thermal break frames” whose each section, namely two uprights and two crosspieces, is formed of three parts, an inner metal section, an outer metal section, and at least one central section of material thermally insulating material such as a plastic material, called an insulating strip.
  • thermally insulating material such as a plastic material, called an insulating strip.
  • actuating and locking members When the frame is an opening, pivoting or sliding, actuating and locking members must be associated with it. These members generally comprise a latch disposed between the two metal sections, and an external operating handle to the frame connected to the latch by a control shaft. These actuating and locking members are further attached to the frame by fastening means such as screws. It is therefore necessary to form in at least one of the metal profiles passage holes for the operating shaft of the handle, and for the fastening means where appropriate.
  • the frame section forms a tubular profile delimited by the metal sections and the connecting bars. This tubular profile defines an enclosed space which is difficult to pierce a wall.
  • the document EP 1 839 770 describes a process of this type.
  • the invention aims to overcome this drawback.
  • the invention aims to provide a punching method to overcome the use of a "mouse".
  • the invention also aims to provide a punching process does not detract from the aesthetics of the frame in which the operation is performed.
  • the punching die is therefore no longer inserted into the profile longitudinally at the end of a holding and guiding rod, but laterally through a previously cut opening.
  • said opening is cut in the connecting bar forming the bottom of the receiving rabbet of the filling panel of said frame.
  • the opening is no longer visible, so that the implementation of the method according to the invention does not in any way affect the aesthetics of the closure.
  • said two profiles are metal profiles and said two connecting bars are of insulating material, said frame thus being thermal break, said opening being formed in a connecting strip of insulating material.
  • said opening is cut by punching.
  • Such a method is particularly effective in the case of a thermal break frame. Indeed, the opening is then performed in a plastic connecting bar that can be punched without difficulty.
  • the connecting strip in which the opening is cut can be connected to the profiles by crimping, each longitudinal edge of said bar being crimped between two respective ribs of each section, said opening being made so that its longitudinal edges are at immediate proximity of the end edges of said ribs, so that said ribs form a punching anvil for said bar.
  • the punching of the connecting strip even if the latter is made of plastic material, can indeed cause its damage, for example by bursting.
  • the use of the crimping ribs as a punching die causes a shearing effect in the material of the bar which avoids this disadvantage.
  • the matrix is positioned transversely by bringing it into abutment on the connecting strip lying opposite the one in which the opening is cut.
  • the matrix is positioned transversely by bringing it into abutment on a rib of at least one of said profiles, inside said closed cross section.
  • the matrix is positioned longitudinally by centering in the cut opening.
  • the matrix is positioned longitudinally by wedging with respect to an external tracing on the wall to be punched.
  • the method according to the invention can be implemented for the production of any profile, in particular all-metal or entirely of plastic.
  • the protection extends to a chassis frame section comprising a filler panel, obtained directly by the method according to the invention.
  • This profile 1 is constituted in the example of an inner metal section 2, an outer metal section 3, connected by two bars 4 and 5 of thermally insulating material such as a plastic material for example of polyamide type.
  • the bar 5 and the sections 2 and 3 form a rebate capable of receiving for example a glazing unit (not shown) of the chassis.
  • the holes 9, 10 are shown to be punched on a wall 18 of the profile section.
  • the figure 2 shows that each of the bars 4 and 5 is crimped by each of its longitudinal edges to one of the metal profiles 2, 3 between two respective ribs 6 and 7 of these profiles.
  • Profile 1 to thermal break thus forms a closed space 8, open only at the two longitudinal ends of the profile 1.
  • the inner metal section 2 comprises, for example, an orifice 9 for the passage of an axis (not shown) for controlling a frame lock and two holes 10 for passing a screw for fixing the corresponding lock (not shown). ).
  • all the orifices 9, 10 defines an arrangement of orifices of variable shape depending on the type of lock, mechanism, or the like that must be associated with the frame.
  • the method according to the invention allows any arrangement of orifices according to needs by adapting a corresponding arrangement of orifices on the punching die 13.
  • the method according to the invention first of all provides for preferentially cutting, in the bar 5 intended to form the bottom of the rabbet of the filling panel, an opening 11 as shown in FIG. figure 3a .
  • This opening 11 is here rectangular and is advantageously made by punching the bar 5.
  • the opening 11 has its longitudinal edges 12 in the immediate vicinity of the edges 6 ', 7' of the ribs 6 and 7 so that the latter form an anvil punching.
  • a matrix 13 for punching the orifices 9, 10 is then introduced transversely at least partly into the opening 11 as shown in FIGS. figures 2 and 3c with the matrix 13 in the punching position.
  • this introduction is advantageously achieved by a first transverse displacement of the matrix 13 or the profile 1 towards each other in a plane substantially parallel to the wall 18 of the profile section 1, corresponding in the example in the plane of the filling panel (not shown), so that the matrix 13 is in the example positioned transversely by bringing it bearing on the bar 4 vis-à-vis the bar 5 having the opening of passing an end portion of the die.
  • the upper surface 15 of this end of the die 13 is then brought into contact with the inner surface of the wall 18 in which the punching of the orifices 9, 10 must be carried out, as shown in FIG. figure 2 , advantageously by means of a second transverse displacement of the matrix 13 or of the profile 1 towards each other in a plane perpendicular to the wall 18 of the profile section 1.
  • the punching operation can then be performed without the wall 18 being deformed by the punching force as shown in FIG. figure 2 .
  • This second translational transverse displacement is made necessary because of the presence of the crimping ribs 6, 7 of the bar 5 having the opening 11 for passing the end of the filler panel.
  • the die 13 has a raised end portion 16, on which the openings 17 for the punch 14 open, as shown more particularly on the figure 3b , able to come to bear on the inner surface of the wall 18 of the section 2 to be punched.
  • the opening 11 preferably made in the rebate bottom strip 5, will have a width slightly greater than the thickness of the end portion of the matrix 13 which must be introduced into the profile 1 through this opening 11, so that this introduction is preferably free without friction or snagging.
  • the matrix 13 is also for example positioned longitudinally by its centering in the opening 11, or alternatively, the matrix 13 is positioned longitudinally by wedging relative to an external tracing on the wall to be punched.
  • FIGS. figures 2 and 3c represent the punch 14 engaged in the matrix 13, unlike the figure 3c on which the punch 14 is not yet engaged in the matrix 13.
  • the punching die 13 is then removed from the profile 1, more particularly from the closed space 8, preferably by two inverse transverse displacements of those described above for the introduction of the matrix in the profile, in order to avoid hang the ribs 6, 7.
