Abstract: A punch head assembly that includes a punch head including a main body having opposite first and second ends, a longitudinal inner bore, a first passageway extending substantially radially from the inner bore, and a second passageway substantially traversing the first passageway. A ball bearing is received in the first passageway. A pin member is received in the second passageway. The pin member is rotationally movable between first and second positions. A driver is coupled to the punch head and includes a stem extending into the inner bore. The stem has an outer ball engagement surface. The punch head is axially movable with respect to the stem. Axial movement of the pin member in the second passageway moves the ball bearing into and out of engagement with the outer ball engagement surface for adjusting an axial position of the punch head with respect to the driver.

Abstract: A method of adjusting punch body assembly, that has a punch body coupled to a driver, by moving the driver with respect to the punch body until a select axial position is reached along the longitudinal axis of the punch body and locking the driver at the select axial position.

Abstract: A biasing assembly for a punching device that includes a punch support member adapted to support a punch and including a head portion and a main portion extending from the head portion. The main portion has a recessed surface. A retaining member is coupled to the punch support member with the punch support member being slidable with respect to the retaining member. A coupling member is disposed between the main portion of the punch support member and the retaining member. A portion of the coupling member engages the recessed surface. A biasing member is supported between the head portion of the punch support member and the retaining member. The punch support member is movable between at least first and second positions with respect to the coupling member.
