Dual Lower Ram Riveting Machine

A drill and rivet machine with a unique dual lower ram has been designed and built. The dual lower ram assembly consists of two horn shaped rams that are mounted at ninety degree angles to one another. Both rams remain operational at all times. When one ram is in place in the front of the machine the other ram is pivoted out to the side of the machine. Each ram has a unique horn shape and carries its own offset lower anvil assembly. The unique horn design allows the ram to reach into high curvature leading edge parts. The operator can select either ram so that a complete ship set of high curvature parts can be produced by the machine with no other tool changes required.
