    摘要: The invention provides a punch press capable of impressing a plurality of holes or other changes in a workpiece. The central core piece of the punch press receives the workpiece and expands until it touches the inner walls of the workpiece. This holds the workpiece in place and prevents any workpiece movement or distortions in the holes formed because of movement of the workpiece. Hydraulic cylinders impel the plurality of punches toward the workpiece at substantially the same pressure and time.

    摘要: An apparatus for forming aligned front and rear hand holes in the front and rear panels of a bag according to the invention has a support having a front face and an oppositely directed rear face adapted to respectively support the front and rear panels of the bag and formed with respective aligned front and rear annular recesses of a shape corresponding to that of the hand holes to be cut. Respective annular front and rear outer holddowns are engageable with the respective faces for pressing the respective panels thereagainst around the respective recesses. An annularly continuous front cutter blade is engageable in the front recess and an annular but discontinuous rear cutter blade is engageable in the rear recess. A rear inner holddown is also engageable with the rear face within the recess. An actuator can press the holddowns against the respective faces and simultaneously press the blades into the respective recesses and thereby cut a piece from the front panel and form an annular but discontinuous cut in the rear panel.

    摘要: A trimming and piercing apparatus of an extremely high operation efficiency which is capable of trimming and piercing a work simultaneously. The apparatus comprises a fixed die provided with a work mounting surface and a piercing bore opened at the work mounting surface, and a movable die displaceable toward and away from the fixed die. A pair of movable blades and a pair of fixed blades are provided in a spaced opposed relation on the movable die and the fixed die, respectively, so that the movable blades are engageable with said fixed blades when the movable die is moved toward the fixed die. A cam slide having a piercing punch is slidably mounted on the movable die. A cam driver is mounted on the fixed die for driving the cam slide to move along the movable die toward the fixed die to place the piercing punch into fitting engagement with the piercing bore in the fixed die as the movable die is displaced toward the fixed die.

    摘要: An apparatus, system, and method for punching holes at any location along the length of an elongate hollow body comprising an expandable die which is insertable into the elongate hollow body. The elongate hollow body may have any shape and be of any length. In operation, the expandable die cooperates with the punch or punches of an external, conventional punch press. The expandable die self-aligns its die cavity or cavities with the punch or punches of the external punch press. The expandable die can expand to support the elongate hollow body during the punching operation to avoid denting or other damage to the elongate hollow body.
