  • Punch and method for piercing holes with a retention structure
    Patent number: 8978431
    Abstract: A punch including a shearing edge formed on an outer periphery of the punch, a cutting edge formed on the distal end of the punch and at least two ramp surfaces provided between the shearing and cutting edges. Each of the ramp surfaces extend at an angle from the distal end to a recessed portion of the shearing edge. The shearing edge, cutting edge and ramp surfaces cooperate to partially form a hole in a part and retain a slug in the hole. A method of forming a hole and a slug control system for a hydro-piercing operation is disclosed.
