Claims

[Scope of utility model registration request]

A metal tube end processing machine that applies plastic working to the outer circumferential surface of the tip of the metal tube by pressing a rolling die onto the outer circumferential surface of the tip of the metal tube fixed by a clamp mechanism. A plurality of swinging pieces each having one end pivotally supported by a plurality of pivots provided in the section, a rolling die pivotally supported on the inner end of each swinging piece, and each swinging piece being pivotally supported. A rotary ring rotatably provided around a pivot shaft, a plurality of guide pieces provided on the front surface of the rotary ring, and a plurality of guide pieces provided on a part of each of the swing pieces to engage the guide pieces, respectively. Further, a guide groove inclined in the circumferential direction, a rotational drive means for rotationally driving the rotary ring using an electric motor as a power source, and a drive speed and amount of drive of the rotary ring by the rotational drive means are controlled. A metal tube end processing machine comprising a controller and a control panel for inputting conditions of the metal tube to be processed into the controller.
