Pipe machining device for forming chamfer at pipe end, has machining element movably fitted at machining head and pushed by centrifugal force of pipe, where force is produced by rotation of machining head

摘要

The device has a machining head (2) rotated around a pipe axis and having a machining element (11) attached to a pipe. The machining element is movably fitted at the machining head and pushed by centrifugal force of the pipe, where the force is produced by rotation of the machining head. The machining head has a centrifugal force body (5) movably attached to the machining head and transmits centrifugal force directly or indirectly on the machining element, where sum of centrifugal forces of centrifugal force bodies striking at the machining head is zero.
