    Abstract: A press apparatus that allows more flexible design for a punch than the conventional technique is provided.
    A workpiece feeding apparatus 45 (a press apparatus) of the present disclosure includes two, namely, first and second biasing mechanism 151, 152 for applying upward biasing force to a knockout pin 53. At the moment of press work, by the first punch 51 and the knockout pin 53 holding a workpiece 90 therebetween and shifting downward to a die 60, the knockout pin 53 receives biasing force from the first and second biasing mechanisms 151, 152 to press the workpiece 90 from below, so as to prevent the workpiece 90 from bulging deformation. Immediately after the press work on the workpiece 90, the first breaking mechanism 153 breaks transmission of biasing force from the first biasing mechanism 151 to the knockout pin 53. While being less pushed by the knockout pin 53, the workpiece 90 shifts down to the discharge position.

    Abstract: A sheet metal blanking die assembly, comprising a lower part, an upper part and guide columns. The die assembly upper part and lower part present flat parallel mutually opposing horizontal portions. The lower flat portion is arranged to receive the sheet metal, the upper flat portion presenting a plurality of punches. On the flat lower portion, blanking recesses are present to receive the respective punches and at least one detachment die, below which a brake is present, said brake presenting a through cavity positioned coaxial to that of the detachment die. The brake presents a plurality of contact zones arranged to brake the fall of the individual laminations and possibly to enable the formation of a lamination pack. Means are provided to cool and/or to lubricate just the contact zones between the laminations or the lamination pack and the brake.
