Claims

[Scope of utility model registration request]

A clamp mechanism that displaces the clamp die as pressure oil is fed into the clamp cylinder to hold down the metal tube to be processed, and a second mechanism that presses the processing die against the tip of the metal tube fixed by this clamp mechanism. By pressing a rolling die onto the outer peripheral surface of the tip of the metal tube using a second hydraulic cylinder on a plastic processing machine having one hydraulic cylinder,
In this metal tube end processing machine combined with a rolling machine that plastically processes the outer peripheral surface of the tip end of the metal tube, pressurized oil is supplied to the clamp cylinder, the first hydraulic cylinder, and the second hydraulic cylinder. 1. A metal tube end processing machine, characterized in that the same supply source is provided, and a force increasing mechanism using a taper cam is provided between the clamp cylinder and the clamp die.
