Pipe bending machine

摘要

A pipe bending machine ( 1 ) includes a bending tool ( 3 ), a pipe feed unit ( 9 ) and a mandrel retractor ( 19 ). A pipe holder ( 8 ) of the pipe feed unit ( 9 ) and a mandrel bar support ( 24 ) of the mandrel retractor ( 19 ) are guided in the longitudinal pipe direction ( 12 ) by a common linear guide system ( 16 ) on the machine base. Alternatively or in addition thereto the pipe holder ( 8 ) and the mandrel bar support ( 24 ) can be moved in the longitudinal pipe direction ( 12 ) by a common drive system ( 15 ) on the machine base.
