Abstract
A portable metal stud punching system has an alignment frame with an infeed alignment port in a first side and an outfeed alignment port in an opposite side. There is a punch and die positioned within the alignment frame. A length of metal stud is inserted through the infeed alignment port with one vertical side of the metal stud disposed between the punch and the die. A first hydraulic unit is attached to the punch and moves a first direction thereby inserting the punch into the die and punching a tab out of the vertical side of the metal stud. A second hydraulic unit moves the punch assembly in a direction perpendicular to the first direction of the first hydraulic unit. After the tab has been punched, the second hydraulic unit advances the metal stud by sliding the punch assembly a distance equal to the desired space between tabs. The punch is retracted by the first hydraulic unit and the punch assembly is returned to its original position by the second hydraulic unit.
