Heat Exchanger Tube Expander System

This machine is a 10 axis servo based system to install the header
plates on a heat exchanger core then expand the ends of the tubes to hold the header plate in place. The operator selects the part to be assembled. The system then uses the servos to set the proper dimensions. The operator then places the core and two headers in the machine. Upon starting the process, the system clamps the core, pushes on the headers, then indexes four (4) sets of tubes at a time and expands the ends of the tube. This is accomplished by inserting a tapered flat pin in the tube and pressing to a specific depth then indexing to the next set of four (4) tubes. When complete, the system retracts and unclamps to allow the operator to remove
the finished part.
