Abstract
A weld bead cutting device is configured such that, a liner made as liner portions are abutted on and welded to each other is rotated around a rotation axis extending in a direction along an abutting direction, and a weld bead is cut with a cutting tool arranged among rollers in a state where the rollers are pressed against an outer peripheral surface of the liner, the rollers being arranged on both sides of the weld bead on the liner in a direction along an extending direction of the rotation axis.
Claims6
A weld bead cutting device configured to cut a weld bead generated on an outer circumference of a welding portion, the weld bead being generated when end edges of two resin members are abutted on and welded to each other, each of the end edges having a ring shape on an open side, the weld bead cutting device comprising:
- a rotation mechanism configured to rotate a workpiece formed as at least the two resin members are welded to each other, the workpiece being rotated around a rotation axis that extends along an abutting direction of the at least two resin members;
- a cutting tool arranged on an outer peripheral side of the workpiece and configured to cut the weld bead;
- at least two pressing rotors arranged on both sides of the cutting tool in an extending direction of the rotation axis, the pressing rotors being configured to be pressed against an outer peripheral surface of the workpiece;
- and
- a reciprocation unit configured to hold the cutting tool and the pressing rotors and reciprocate the cutting tool and the pressing rotors relative to the workpiece along a direction orthogonal to the extending direction of the rotation axis.
A weld bead cutting method by which a weld bead generated on an outer circumference of a welding portion is cut, the weld bead being generated when end edges of two resin members are abutted on and welded to each other, each of the end edges having a ring shape on an open side, the method comprising:
- rotating a workpiece formed as at least the two resin members are welded to each other, the workpiece being rotated around a rotation axis extending along an abutting direction of the at least two resin members;
- and
- cutting the weld bead with a cutting tool in a state where pressing rotors are pressed against an outer peripheral surface of the workpiece on both sides of the weld bead in an extending direction of the rotation axis, the cutting tool being faced with the weld bead.
