Profiling die mechanism applied to pipe bending machine

The invention discloses a profiling die mechanism applied to a pipe bending machine. The profiling die mechanism comprises a machine head base, a profiling die and a driver. The profiling die is arranged on the machine head base in a horizontal sliding manner. The driver is arranged on the machine head base and located below the profiling die and is used for driving the profiling die to horizontally slide relative to the machine head base. The driver is in transmission connection with the profiling die through a transmission mechanism located below the profiling die. In the profiling die mechanism, the driver and the transmission mechanism are arranged below the profiling die, in the work process, the driver, the transmission mechanism and the profiling die are not in the same horizontal space, the size of a machine head in the horizontal direction is reduced, and operation of workers is convenient. 本发明公开了种应用在弯管机上的靠模机构，包括：机头座、靠模和驱动器，靠模可水平滑动的设置在所述机头座上；驱动器设置在所述机头座上并位于靠模的下方，用于驱动所述靠模相对于机头座水平滑动，所述驱动器通过位于靠模下方的传动机构与
