Abstract (en)

[origin: EP1640081A1] The stamping machine (2) has a stamping tool (16) pushing a rivet against a top sheet (A). The top sheet rests on a bottom sheet (B). The river deforms the sheets and forcing them into a matrix (6). A cylindrical holder piece (22) presses the sheets down against the rim of the matrix. A cylinder (4) contains a first piston (12) with a piston rod pressing down on an intermediate piece and the stamp. There are hydraulic fluid connections (24,26) to chambers (10a) above and (10b) below the first piston. A second piston slides on the piston rod of the first piston and pushes on the holder piece. It has throttle channels (28) allowing hydraulic fluid to flow through it slowly.
