ABSTRACT:
Tube forming apparatus for forming a tubular part having an enlarged diameter end section at one end with an adjacent short radius bend is disclosed. A straight length of tubing is magnetically positioned between die members and fixedly clamped with opposite ends of the tube projecting from opposite ends of the die. One end of the clamped tube is then enlarged to form the enlarged end section. A magnetic transfer device is engage with the other end of the clamped tubing and, with the die opened, the tube is transferred to a second position between the die members which are closed to clamp the enlarged end section only with the remainder of the tubing projecting from the die. A tightly fitting plug member is seated in the interior of the clamped end section and a bending member the bends the projecting end of the tubing against an anvil formed on one of the die members.
