Embodiment Construction

[0029] Figure 1 to Figure 3 A trunk lid of a motor vehicle is shown.

[0030] as in figure 1 and figure 2 As shown, the trunk lid 2 basically includes an outer panel 4 , an inner panel 6 assembled to the outer panel, and a trim part 8 attached to the inner panel 6 .

[0031] as in Figure 1 to Figure 3 As shown, the outer panel 4 includes a substantially flat main portion 4 1 , the first curved part 4 2 and the second curved section 4 3 . first bend 4 2 with main part 4 1 at an angle of at least about 90°. Of course, this angle can have different values, eg between 60° and 120°. Second curved part 4 3 with the first bend section 4 2 Also at an angle of at least about 90°. Of course, this angle can also have different values, eg between 60° and 120°. Second curved part 4 3 A flange is formed having a recess 5 for receiving the lighting means of the number plate to be fixed to the trim part 8 1 and opening 5 2 .

Abstract

A press-tool (10) for forming a flange(43) of a metal sheet (4) with a stamping press comprises a lower body (12) with a die (14) for receiving the sheet (4) and a first slider (22) for forming the flange (43) of said sheet (4), an upper body with a first cam (28) for moving the first slider (22) in an operating direction (L) towards the die (14) for forming the flange (43), and a second slider (24) on the lower body (12), configured to be moved by the first cam (28) in an operating direction (T) towards the die (14) for forming the flange (43), said direction (T) being transverse to the operating direction (L) of the first slider (22).

Description

technical field [0001] The present invention relates to the field of stamping and forming sheet metal blanks such as body parts of vehicles. More specifically, the invention relates to a pressing tool for a punching machine and a method for press-forming sheet metal. Background technique [0002] The patent document with the publication number FR3008910A1 discloses a press tool for flanging and folding simultaneously on the same edge of a metal sheet. The pressing tool includes a slide on the upper body that includes first and second working surfaces that are inclined relative to each other. The slider is movable downward to allow the first working surface to perform flanging operations on the edge of the board. Then, the slider cooperates with the cam on the lower body to move in a direction inclined with respect to the vertical direction to allow the second working surface to perform a folding operation on the flange. The advantage of this teaching is that it integrates...
