  • Patent number: 4914996
    Abstract: A pressing tool including means for cutting a blank from a strip fed longitudinally into the tool. The cutting means comprise a stationary lower punch carried by a press table and a vertically mobile upper die normally located above the punch and intended to be moved in the direction of this punch by the mobile press slide. Means are provided for cutting the end scrap from the strip, these means comprising shears having a stationary blade and a mobile blade, a device for transfer of a cut blank, prestamped blank, or stamped blank, from the station which the blank occupies to the following station, and means to lift each cut blank to the level of the transfer device. The stationary blade is carried by the support of the punch while the mobile blade is carried by the die.

  • Patent number: 4706369
    Abstract: A tapping machine has a base plate fixed to one of the platens, a spindle extending along a spindle axis between the platens in the closing direction of the press actuating the machine, and a nut threaded on the spindle. The nut is normally rotatable about the spindle axis on the base plate and the spindle is fixed nonrotatably about the spindle axis on the other platen so that relative displacement of the platens rotates the nut in the base plate. An element displaceable on the base plate along an element axis but nonrotatable on the base plate about the element axis carries a plurality of tap holders generally fixed relative to the element axis in the element and rotatable in the element about respective tap axes parallel to the element axis. Respective taps are fixed axially and rotationally in the holders.
