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.
Claims22
An apparatus to remove and process an external weld bead from a welded pipe traveling in a downstream direction, comprising:
- a tool holder carrying a planing tool, which separates the weld bead from the pipe while the pipe travels in the downstream direction;
- a chopper spaced downstream of the planing tool in the downstream direction of travel of the pipe to cut the separated weld bead into chips;
- and
- a body supporting the planing tool and the chopper and including a passage disposed between the planing tool and the chopper to guide the separated weld bead in the downstream direction of travel of the pipe through the body from the planing tool to the chopper.
An apparatus to remove and process an external weld bead from a welded pipe traveling in a downstream direction, comprising:
- a tool holder carrying a planing tool, which separates the weld bead from the pipe;
- a chopper located downstream of the planing tool to cut the separated weld bead into chips;
- and
- a body supporting the planing tool and the chopper and including a passage disposed between the planing tool and the chopper to guide the separated weld bead downstream through the body from the planing tool to the chopper, wherein the body includes an upstream end to support the tool holder, which is adjustably coupled to the upstream end, and further comprising an adjustment apparatus coupled between the body and the tool holder to adjust the tool holder, and including an adjustment shaft and an adjustment wheel rotatably supported on the body by a block coupled to the body, wherein the adjustment wheel is threadingly engaged on the adjustment shaft, which is coupled at one end to the tool holder.
An apparatus to remove and process an external weld bead from a welded pipe traveling in a downstream direction, comprising:
- a first cutting device to separate the weld bead from the pipe while the pipe travels in a downstream direction;
- a second cutting device spaced downstream of the first cutting device in the direction of travel of the pipe to cut the separated weld bead into chips;
- and
- a guide disposed between the first and second cutting devices and spaced downstream of the first cutting device in the direction of travel of the pipe to guide the separated weld bead in the downstream direction of travel of the pipe from the first cutting device to the second cutting device.
An apparatus to remove and process an external weld bead from a welded pipe traveling in a downstream direction, comprising:
- a body including a passage therethrough;
- a tool holder supported on the body and carrying a planing tool, which separates the weld bead from the pipe while the pipe travels in the downstream direction;
- and
- a chopper supported on the body and spaced downstream of the planing tool in the downstream direction of travel of the pipe to cut the separated weld bead into chips;
- wherein the body passage guides the separated weld bead in the downstream direction of travel of the pipe through the body from the planing tool to the chopper.
An apparatus to remove and process an external weld bead from a welded pipe traveling in a downstream direction, comprising:
- a guide;
- a first cutting device supported on the guide to separate the weld bead from the pipe while the pipe travels in a downstream direction;
- a second cutting device supported on the guide and spaced downstream of the first cutting device in the direction of travel of the pipe to cut the separated weld bead into chips;
- wherein the guide guides the separated weld bead in the downstream direction of travel of the pipe from the first cutting device to the second cutting device.
