ABSTRACT:
A method and apparatus for expanding cylinders for work hardening, especially for large diameter cylinders and cylinders of great length, are disclosed. The cylinder is clamped between two flanges and a shaft is inserted coaxially through the cylinders and through the flanges to reduce the force applied axially to the flanges while pressure is applied to the interior of the cylinder. Various arrangements for adjusting the position of the flanges to accommodate for expansion of the cylinder are disclosed.
