  • Publication number: 20120103209
    Abstract: A pneumatic press with high slide acceleration and velocity is equipped with an arrangement trigger mechanism for holding the slide, upper die, and punch in place until air pressure force in tons is exerted against slide opposite the upper die and punch. When the trigger mechanism releases the slide, upper die, and punch in a short travel the velocity is very high. This will permit the punch to enter the part material at the strain rate of the material, thus eliminating burrs, reducing fatigue initiation sites on the part material surface where the punch goes through the material. Also will permit forming parts of uniform thickness, impact powder titanium to form sheet, and stamp parts against flat sheet of polyurethane with punch having the shape of the part.
