    The folding tool with wedge drive is used for joining vehicle door outside and inside panels. The tool is used pref. for doors whose edge slopes inwards. The tool wear is reduced and idle movements of the wedge slider are avoided. The slider carries out only reciprocating movements. The front end of the wedge slider (4) has a vertical slider (5) provided with a bending profile (6). Above this slider is arranged the ram (7) held on the tool upper part. The arrangement uses a simple one sided profiled wedge ram (3). This pushes the bending profile sideways against the door panel assembly edge.

    (5) FOLDING STAMP
    one
    The invention relates to the processing of metals by pressure, in particular to a tooling for joining sheet material parts.
    Known folding stamp containing the bottom plate, bending nodes, each made in the form of interacting with the wedge of the slide mounted on the slide of the bending bar and mounted on the top plate of the beam Cl 1.
    However, in the well-known stamp, an additional wedge pair is used to remove the slide with the bending bar from the working area, which is associated with an increase in the dimensions of the stamp and an increase in metal consumption.
    The aim of the invention is to reduce the metal intensity and reduce the dimensions of the stamp.
    To achieve this goal, the bending plate is spring-loaded in the direction of the punch axis, and the slider is mounted on the bottom plate.
    FIG. I- shows the stamp at different stages of deformation.
    The stamp comprises an upper plate 1 with wedges 2 fixed on it, bars 3 and a clamp t provided with compression springs 5. On the bottom plate 6, in accordance with the shape of the part, there are placed sliders 7, on the front wall of which, on bearers B, bending bars 9 are installed. on the plate 6 are plates 13 and 1 if the slides and stop plates 15 associated with the springs 16. In the center of the plate 6 there is an insert 17 for the workpiece 18, consisting of an outer with a curved edge 19 and an inner door sheet, and stops 20 ,
    The stamp works as follows.

    Claims (1)
    [1]
    When the press slide is in the upper position, the blank 18 is pressed onto the liner 17 of the UK39, and when the slide is lowered, the clamp i presses it against the liner 17. The wedge 2 moves the sliders 7 towards the folded edge 19. The blanks and bending plates bend the edge 19 to almost horizontal position At one end, the slides 7 are flexible and stop, and the beams 3 come into contact with the holders, 8 strips 9 and lower them down. In this case, the bottom surface of the bending bars 9 is adjacent to the curved edge 19 and to the inner sheet of the door. After that, all elements of the stamp are returned to their original position; and the workpiece is removed from the stamp. Claims of the invention A folding stamp comprising a lower plate and bending knots, each made in the form of a slide interacting with a wedge, mounted on the slider of the bending bar and fixed on the top plate of the beam, characterized in that in order to reduce the metal intensity and reduce the dimensions of the stamp, the bending bar made spring-loaded in the direction of the axis of the stamp, and the slider is installed on the bottom plate.
