APPARAT TIL OVERSKAERING AF ROER

摘要

An apparatus for parting pipe has two shearing members bearing against each other and mutually movable along a cutting plane and with holes for the pipe which form exterior shearing edges. The pipe bore is supported by a mandrel divided into two sections mutually displaceable and forming interior shearing edges. The moving shearing member is driven by a crank mechanism, including a single crankshaft, at a mounting arrangement spaced from a bearing arrangement via which the fixed and the movable shearing members are mounted and guided and in which an elongate hole has its longitudinal axis directed towards the crankshaft and a bolt adapted to said hole.
