  • Publication number: 20140056662
    Abstract: An external weld bead is removed and processed from a welded pipe traveling in a downstream direction. The weld bead is separated from the pipe, guided through a guide passage having an inlet and an outlet, and cut into pieces at the guide passage outlet in a location above the pipe.

  • Patent number: 8123106
    Abstract: An external weld bead is removed and processed from a welded pipe traveling in a downstream direction. The weld bead is separated from the pipe, allowed to flow in a downstream direction, and is guided downstream and cut into chips at a location downstream of where the weld bead is separated from the pipe. Also disclosed is weld bead cutting tool including a cutting edge at an upstream end of the tool, a guide feature disposed downstream of the cutting edge and extending toward a downstream end of the tool, wherein the guide feature widens from the upstream end toward the downstream end.

  • Patent number: 7695224
    Abstract: Methods of producing a pipe include curling a skelp into a cylindrical shape by bringing laterally opposed edges of the skelp together to form a seam, butt welding the seam to define the pipe downstream of the skelp, thereby leaving a radially inwardly extending weld bead. The weld bead is deburred off the pipe according to a depth of cut of a cutting tool. The depth of cut may be adjusted during deburring, and/or rotation of the cutting tool may be adjusted during deburring. The methods may be carried out using one or both of an adjustment device carried by a housing to pivot an adjustment member for adjustment of an upstream guide to adjust a depth of cut of the cutting tool into the weld bead, or an adjustment device carried by the housing and coupled to the cutting tool to rotate the cutting tool during deburring.

  • Patent number: 4801226
    Abstract: A broaching machine and method for machining main bearings and crankpin bearings on a crankshaft for an automotive engine wherein a plurality of removable cutting tool inserts are arranged on a horizontally reciprocating slide below a rotating crankshaft to machine a plurality of bearings and distribute machining forces over the machining operation during a single pass of the slide. The slide also serves as a transfer device for loading and unloading crankshafts into the machine. An air bearing can be developed between the slide and the tooling to assist the operator in removing the tooling from the slide.

  • Patent number: RE28896
    Abstract: A cutting tool assembly comprising a cutter body which mounts at each of its opposite sides on one end and at the proper cutting angles a relatively narrow rectangular shaped cutter blade and a triangular shaped cutter blade. These cutter blades are maintained in an operative position in engagement with each other by a clamping element that is releasably joined to the cutter body at an angle that is related to the cutter cutting angles. Support and locking provisions further facilitate maintaining this operative position. Between these cutter blades a holder for another cutter blade is supported on the cutter body. This latter cutter blade and the triangular shaped blades are aligned along with the rectangular shaped cutter blades so as to machine a plural surface profile on a work piece.
