US 2002/0153355 A1 · Welded tube internal surface bead cutting apparatus, chip processing method and apparatus, and weld spatter processing apparatus

Abstract

In the bead cutting apparatus of the present invention a cutting tool 22 is provided on the distal end of an impeder 21 so as to be able to swing. This swing uses a first bolt 45a as a fulcrum and is within a range allowed by the difference between the external diameter of a second bolt 45b and the internal diameter of a second hole 47. A blade tip portion 33 is provided at the distal end of a cutting tool body 32 and is provided at the impeder 21 side such that a cutting blade 34 can make contact with an internal surface bead B of a tube P. A spring member 38 is fixed by a fixing member 39 to a position partway along the cutting tool body 32 on the opposite side thereof to the cutting blade 34.
