Abstract
A mechanical arrangement for processing pipes by cutting using a cutting beam has a cutting head, a pipe holder, a catching lance and a stripper. The stripper is transferable relative to a processing axis of the cutting head in the longitudinal direction of the pipe to various positions by means of a positioning movement.
Claims18
A mechanical arrangement for processing pipes by cutting using a cutting beam, the mechanical arrangement comprising:
- a cutting head from which a cutting beam may be directed onto a pipe to be processed, along a processing axis of the cutting head and in the transverse direction of the pipe, the cutting beam and the pipe being movable relative to each other in the circumferential direction of the pipe with at least one pipe portion being severed,
- a pipe holder which, viewed in the longitudinal direction of the pipe, is disposed on a first side of the processing axis of the cutting head and is configured to fix the pipe to be processed,
- a stripper, disposed on a second side of the processing axis of the cutting head which is opposite the pipe holder in the longitudinal direction of the pipe,
- a catching lance that is insertable into the interior of the pipe to be processed, on the second side of the processing axis of the cutting head with a projecting length relative to the stripper in the longitudinal direction of the pipe and towards the processing axis of the cutting head,
- the catching lance being configured to receive at least one severed portion of the pipe on a side of the stripper which is towards the processing axis of the cutting head, and
- the catching lance being movable relative to the stripper in the longitudinal direction of the pipe with a withdrawal movement away from the processing axis of the cutting head, to strip the pipe portions off the catching device,
- wherein the stripper is transferable relative to the processing axis of the cutting head in the longitudinal direction of the pipe to various positions by a positioning movement.

A method of processing pipes by cutting using a cutting beam, the method comprising:
- fixing the pipe to be processed in a pipe holder which, viewed in the longitudinal direction of the pipe, is disposed on a first side of the processing axis of the cutting head,
- providing a stripper, disposed on a second side of the processing axis of the cutting head which is opposite the pipe holder in the longitudinal direction of the pipe,
- inserting a catching lance into the interior of the pipe, on the second side of the processing axis of the cutting head, with a projecting length of the cutting lance relative to the stripper extending in the longitudinal direction of the pipe and towards the processing axis of the cutting head,
- effecting relative movement of a cutting head from which a cutting beam may be directed onto the pipe and/or the pipe relative to each other in the circumferential direction of the pipe while directing the cutting beam onto the pipe, with at least one pipe portion being severed,
- depositing at least one severed portion of the pipe onto the catching lance on a side of the stripper which is towards the processing axis of the cutting head,
- moving the catching lance relative to the stripper in the longitudinal direction of the pipe with a withdrawal movement away from the processing axis of the cutting head, to strip the pipe portions off the catching device, and
- transferring the stripper relative to the processing axis of the cutting head in the longitudinal direction of the pipe to various positions by a positioning movement.
