초록

A tube member is placed in a die having a plurality of nodules formed in the cavity thereof. A chamber is formed between a mandrel and end piece within the tube. The mandrel is positioned adjacent a first of the nodules and the chamber is pressurized during a hydroforming cycle to form a node on the tube by simultaneously expanding a portion of the tube outward and feeding the tube linearly into the die cavity. A mechanism for feeding the tube linearly is external to the die cavity and has a member in abutment with one end of the tube. During a positioni...
