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.

摘要： A metal sheet having a pair of thin portions on respective marginal edges thereof which are joined to a remaining portion of the metal sheet via respective corners is centered by positioning the center between the corners as the center of the metal sheet. Then, elements are blanked out of the metal sheet. The elements remain joined to the metal sheet by respective connectors which are formed in the respective thin portions of the metal sheet, the bodies having respective lower edges formed in the respective thin portions of the metal sheet. The elements are separated from the metal sheet by cutting off the connectors along the lower edges of the bodies.
