  • Patent number: 9364884
    Abstract: Provided is a die trim section with a recess adapted to retain slugs in a stamping process. The recess may be added to existing die inserts via wire EDM, conventional surface grinding or other suitable methods. The lateral depth of the recess in the trim section is approximately equal to the cutting clearance of a die trim or blank insert. The recess is preferably tapered inward toward the die opening, wherein the upper portion is at the die level and the bottom portion is within the die trim insert interior. The recess creates a small tab on a slug that is wedged into the trim section, preventing the slug from being pulled upwards when the punch is withdrawn. Configurations of the recess vary depending upon slug size and material thickness, cutting clearance, dimensions of the trim section, and dimensions and configuration of the finished product.

    Abstract: An apparatus for processing a hole with a rounded edge includes a punch having a rounded shape formed at a base portion of a cutting tip, and a die supporting a peripheral edge of a pierced hole formed through piercing by the cutting tip of the punch with a pressure receiving surface perpendicular to a punch axis. By driving the punch to make a single stroke motion, a hole is pierced in a work piece by the cutting tip of the punch to form the pierced hole and the rounded shape of the cutting tip is transferred onto a ridge portion on the side of a design surface of the pierced hole. This permits efficient processing of holes with a rounded edge. In addition, by supporting the peripheral edge of the pierced hole with the pressure receiving surface, a uniform and highly accurate rounded shape can be formed on the ridge portion of the pierced hole.

A lower ramp is disposed within the housing and, when rotated, raises the punch to engage the die. The lower ramp may be rotated regardless of the orientation of the punch tool. Thus, the punch tool may be used even when in an inverted position.

  • Patent number: 7587830
    Abstract: A knockout punch is provided with a member such that when the punch and the die are drawn together by the draw stud to make a hole in a workpiece, the member on the punch will locate the punch assembly in a pilot hole. In three embodiments of the invention, the member is formed integrally with the punch and extends from the punch proximate to a bore in the punch which is used to connect the punch to the draw stud. In another embodiment of the invention, the member is provided as an insert which is connected to the punch within a counterbore. The punch is also provided with a pair of piercing portions for piercing through the workpiece after the member has centered the punch assembly with the pilot hole and a pair of cutting portions for shearing the workpiece after the piercing portions have pierced the workpiece.

    Abstract: A flatbed punching module for punching a printing material includes an upper platen and a lower platen which can be moved by a drive relative to the upper platen that is fixed to a frame, in order to perform a punching stroke for punching the printing material passing between the upper platen and the lower platen, resulting in the lower platen engaging with or being thrown onto the upper platen. As a result, the printing material can be processed through the use of at least one punching die. At least one printing material transport device for guiding the printing material, is held fixedly on the movable lower platen. The flatbed punching module can advantageously be used in a flatbed punch for processing a printing material web.
