Claims

[Scope of utility model registration request]

A clamp mechanism that displaces the clamp die as pressure oil is fed into the clamp cylinder and holds down the metal tube to be processed, and a hydraulic pressure that presses the processing die against the tip of the metal tube fixed by this clamp mechanism. In a metal tube end processing machine having a cylinder, a guide rod is provided on the side of the processing die that is displaced by the hydraulic cylinder, parallel to the moving direction of the processing die, and a guide rod is provided along the guide rod. It is supported by this guide rod so that it can freely move and swing around this guide rod, and as it swings, its tip
a positioning arm positioned at a portion where the tip of the metal tube can freely collide; a switch that is connected and disconnected as the metal tube collides with the tip of the positioning arm;
A controller that operates the clamp mechanism and hydraulic cylinder based on signals from this switch, and a cam that swings the positioning arm about the guide rod as the processing die moves to the tip of the metal tube. When the tip of the metal tube collides with the tip of the positioning arm, the controller uses a clamp mechanism to hold down the metal tube, and uses a hydraulic cylinder to move the processing die to the tip of the metal tube. A metal tube end processing machine that functions in a way that it presses toward the end of a metal tube.
