Conical Expander

The machine is used for forming conical shape bodies out of cylindrical form welded bodies. This machine essentially consists of an expanding mandrel which when expanded hydraulically gives the desired conical shape to body.

The round welded body is fed into the mandrel while mandrel is in closed position and on expanding the body takes final desired shape determined by the die. After stretching the mandrel comes back to close from thereby releasing the conical body.
