ることができる。(Effects of the Invention) In the pipe processing machine according to the present invention, the midpoint between the pairs of parallel supports of the upper contact part, left contact member, and right contact member is always an equilateral triangle, regardless of the size of the pipe diameter. Located at each apex position, the setting state is extremely stable, and the left and right abutting members are swingable, making it easy to set up, creating a strong reaction force when cutting pipes with the cutting blade and chamfering with the chamfering blade. Even when the tube is rotated along the tube circumference by the tube circumferential movable attachment, stability is increased by multiple left tension rods, right tension rods, and parallel contact rollers with sufficient axial length. year,
It can be turned smoothly without slight movement, and can be applied to a wide range of pipe diameters.It is especially effective when applied to large-diameter pipes with a diameter of 40 cm or more, and is suitable for beveling when welding pipe ends together. It can be used to significantly improve work efficiency.
