Apparatus for removing burrs from welded material

摘要

A scarfing apparatus for removing a weld bead from a tube being produced by a continuous method, wherein the tube enters one end of a hollow spindle which rotatably supports a scarfing tool holder on which is mounted a tool bit. The tool bit has an arcuate shape having a segment which extends 180 DEG or less about the periphery of the tube. The other end of the spindle is provided with a sensing device which, in conjunction with a power unit and control means, applies oscillatory rotational movement to the spindle to thereby cause the tool bit to rock back and forth across the surface of the moving tube to remove the weld bead. The tool holder is provided with an undercut section adapted to receive securing means for mounting the tool bit in a manner to facilitate rapid removal thereof for installing a new tool bit without ceasing the operation of the continuous tube-forming apparatus.
