ABSTRACT:
A press-driven tool set for joining sheet metal work pieces comprises a die member and a punch member. The die member includes an anvil spaced by a deep gap from a forming member. Deformed material may flow into the gap without filling it so as to cope with thickness tolerances. Debris, such as oil and chips, may collect in the gap. The forming member may be comprised of segments which can be spread apart, facilitating removal of connected work pieces.
