Principle

This induction heating bending machine uses inductors to locally heat steel pipes. This results in a narraw heat band in the shape to be bent. The shape is firmly held by a clamp at a desired radius which is mounted on a free pivoting arm. The shape is pushed through the inductor by an accurate drive system which causes the hot section to form the bend at the set radius. The bent part is then cooled by the circulating water from the closed cooling water tower to fix the bending shape.
