ABSTRACT:
An automatic tube tee forming and trimming system uses a single apparatus for milling a hole in a tube, pulling a forming die through the milled hole, and face trimming the resulting pullout joint to the desired height. The forming die is pulled out through the hole via a universal driver which is simply attached to the drawbar without requiring any twisting to lock the assembly. The system may automatically conduct each of the steps once the tube is loaded into the apparatus. The apparatus completes the tube tee forming and trimming process in a relatively small cell, without the need to travel out to another factory area, within a relatively short period of time, and with minimal use of manual labor.
