Claims

[Scope of utility model registration request]

In an electric resistance welded steel pipe inner surface bead cutting device in which an upper roller and a lower roller that contact the inner surface of the tube and a cutting tool that cuts the tube inner surface bead are integrally incorporated into a holding member, the lower roller is composed of two pieces. , are arranged so as to make the same predetermined angle with respect to the vertical line, and on the lower surface of the holding member slightly upstream of these lower rollers, the spacing between one end of the holding member is narrow on the downstream side in the direction of movement of the pipe, and on the other side. An apparatus for cutting an inner surface bead of an electric resistance welded steel pipe, characterized in that a partition member formed in a V-shape in which the interval between ends widens toward the upstream side is attached to the lower surface of the holding member via an elastic material.
