Zusammenfassung:UPSETTING OF TUBE ENDS A method and apparatus for upsetting a tube end using a one-piece upset die. The tube is heated at the end to be upset and secured in a gripper clamp so as to remain stationary during the upset operation. The upset die is hydraulically forced over the tube end and a mandrel is hydraulically positioned into the tube end. A longitudinal compressive force is then hydraulically applied to upset the tube end. The upset die is hydraulically pulled off the upset tube and thereby accomplishing removal of the tube from the onepiece die without damage to the tube or the die.
