Definitions

  • This invention relates to a method of manufacturing vehicle doors from sheet metal elements preshaped by pressing.
  • the method of this invention avoids the chief drawback and provides, in a much simpler manner, vehicle doors having an improved mechanical strength;
  • This method consist in manufacturing a door provided with a window opening from three pressed elements or sections constituting the one an external door panel in which the window opening is formed, the second element constituting the inner box-sectioned structure in which the window opening is also formed, the third element constituting a window frame provided with extensions for guiding the winding window, said third element consisting of channel sections having their side flanges directed toward the middle of the opening.
  • the edges of the window openings are bent inwards of the door at right angles to the general plane of the door.
  • the panel and box-sectioned elements are applied against each other with the window frame interposed therebetween so that said bent edges of the window openings engage each the frame along each flange of the channel section, respectively. Said edges are each folded respectively against the inner face of the corresponding flange of the channel section by means of a crimping operation, while the peripheral edge of the outer panel element and of the boxsectioned element are also folded on each other.
  • peripheral edge of the external panel element may be flanged down in the same direction as the edge of said opening, so that it can fit over the peripheral edge of the box-sectioned element.
  • the three elements mentioned hereinabove are assembled by crimping in two steps.
  • the flanges of the channel section of said frame element are crimped into the flanged edges of the window openings but only at the corners of said openings, and simultaneously a prefolding of one of the peripheral edges on the other edge isaccomplished.
  • the flanges of the remaining portions of the frame element are crimped while the flanging of one of the peripheral edges on the other edge is completed.
  • FlG. ii is an elevational view showing a box-sectioned door element
  • FIG. 2 shows a window frame element
  • H6. 3 shows a window frame element
  • PEG. 3 is an elevational view showing an external door panel element
  • H05. 5 to 8 inclusive are diagrammatic sectional views showing crimping tools in the different positions providing the first assembling step
  • FIG. 9 shows one fraction of the door upon completion of the first assembling step
  • FIG. w to 13 are diagrammatic sectional views showing the crimping tools in the various positions providing the second assembling step.
  • FIG. 14 shows one fraction of the assembled door.
  • the openings and accessories for operating, closing and locking the door and its winding windows are omitted from the drawing, the same also applying to the joints, beading, and trim.
  • the window is of the type adapted to receive a sliding pane or winding glass, and in this case the frame element is open topermlt the passage of said glass and comprises downward extensions for guiding the glass.
  • the window may also receive a fixed window pane, and in this case the frame element is closed at the bottom.
  • FIGS. 1, 3 and 4 show respectively the box-sectioned element 1 and the external panel element 2 of the door, as obtained from the pressing operation.
  • the bottom 3 of box-sectioned element 1 constitutes the inner panel of the door.
  • the peripheral edge 4 of this box-sectioned element is bent outwardly in a plane substantially parallel to the general plane of the box-sectioned element.
  • the peripheral edge 5 of the external panel 2 is bent inwardly of the door in a direction at right angles to the general plane of this panel.
  • the window opening formed in the external panel 2 is also cut out from a flat-bottomed pressed part 8 and the edge 9 of this opening (except for the lower horizontal portion thereof) is bent substantially at right angles to the bottom 8, i.e. in the same direction as the peripheral edge.
  • the window frame 10 comprising lower extensions 10 and 10 consists of a channel section having its side flanges l1 and i2 directed substantially toward the middle of the window opening.
  • the box-sectioned element 1 and the external panel 2 are so applied against each other, with the frame 10 interposed therebetween, that the edges 7 and 9 of the window opening each engage the frame along the edges of the flanges 11 and 12 respectively, the bottoms 6 and 8 of the pressed portions engaging said flanges ll and 12 respectively, while the peripheral edge 4 of box-sectioned element ll fits into the peripheral edge 5 of the outer panel element 2.
  • the three elements 1, 2 and 10 are then disposed between the press tools illustrated in FIG. 5.
  • These tools consist of a movable block 13 rigid with a folding member l4, these two members being disposed in front of the box-sectioned element, of a die 15 receiving the external panel thereon, and of a punch 16 slideably mounted on the die 15 for movement in a direction parallel to the plane of the window frame and oriented towards the opening formed between the two flanges of the channel section.
  • the folding member 14 has an operative surface 17 consisting of a plane inclined by about 45 in relation to the plane of the door, under which the edge 5 of the external panel 2 is disposed as shown.
  • Power means capable of imparting a movement of translation and consisting for example of cylinder piston actuators are provided for moving the movable block 13 towards and away from the die 15, and to move these two members jointly in one of the two directions in relation to the fixed frame structure of the press (not shown).
  • a frame structure element comprises a cam member 18 having an oblique or skew operative surface l9 adapted to coact with a corresponding sliding or rolling member 26 rigid with the punch 16 in such a way that during the upward movements of the die in relation to said frame structure, said member 20 engages the surface 19 and thus causes the punch 16 to slide in the direction of the opening or bottom of said channel section.
  • the above-described device operates as follows during the first crimping stages:
  • FIG. 8 illustrates the manner in which the punch 16 completes the folding of the edges 7 and 9 of the opening against the inner face of flanges 11 and 12.
  • a suitable return member 23 such as a spring urges the punch 16 away from the channel section, i.e. in the direction of the arrow 24.
  • FIG. 9 only the comers of the window opening, or the portions adjacent thereto, are crimped during this first crimping step.
  • the second step is performed by using a tool differing from the preceding one only by the fact that the folding member having an oblique working face is replaced by a working surface substantially parallel to the general plane of the door (see FIG. 10.)
  • the movable block 26 and the die 15 are moved towards each other the peripheral edge 5 of the outer panel 2 is folded against the peripheral edge 4 of boxsectioned element I (FIG. 11).
  • the punch 16 engages the gap formed between the flanges 11 and 12 of the window frame while the movable block 26 and die 15 perform jointly their movement of translation.
  • the cam 18 engages the slide member 20 rigid with punch 16 (FIGS. 11, 12 and 13) which completes the crimping on the right-hand portions of the window frame (FIG. 14).
  • a method of manufacturing vehicle doors having a window and consisting of three stamped metal elements including the steps of folding the edges of said window openings inwardly of the door at right angles to the general plane of the door, applying the first and second elements against each other while interposing the third element therebetween, folding the window opening edges each against the internal face of the corresponding flange of a channel section by a crimping operation.
  • a method of manufacturing vehicle doors comprising a window and consisting of three stamped sheet metal elements forming the external door panel in which the window opening is formed, the internal box-sectional door panel in which the window opening is also formed, and inbetween said panels a window frame in which the channel sections have their side flanges directed towards the middle of the opening, including the steps of assembling the frame and the panels so that the frame element is engaged, along each flange of the channel section, between corresponding peripheral flanges of the window opening of the outer and inner panels, the opposite flange of said panels being directly applied against each other, crimping the flanges of said channel section in the corner portions of the frame element while performing the preliminary bending of one of the peripheral edges on the other element in one single pressing operation, and crimping the flanges of the remaining portion of the frame element while completing the folding of one of the peripheral edges on the other element in one single pressing operation.
