METHOD AND APPARATUS FOR LONGITUDINAL AND ROTATIONAL ALIGNMENT OF PIPE FOR BENDING WITH AN AUTOMATIC PIPE BENDER

摘要

Method and apparatus for longitudinal and rotational alignment of a pipe for bending with an automatic pipe bender wherein an elongate length measuring template having index marks spaced along the length thereof is arranged on a work bench aligned with the pipe bender, a plurality of indexing plates are moved along the work bench to align indexing pins extending therefrom with the index marks on the length measuring template, and a rotation disc is attached to the trailing end of a pipe to be bent. The rotation disc is aligned with successive indexing pins for longitudinal alignment of the pipe for successive bends, and the rotation disc is rotated to align bores in the peripheral rim thereof with the indexing pins for rotational alignment of the pipe for successive bends.
