A pipe assembly tool adapted to swedge a ring onto the overlap of a pair of telescoped pipes for securing them together, comprises a pair of aligned swedge die blocks, each having opposed semicircular channels of semicircular cross section, adapted to receive a ring of circular cross-section upon the overlap of a pair of telescoped pipes. A power cylinder has a cross head which mounts a pair of die supports at their one ends. The die blocks span and are mounted upon the die supports at their other ends. A piston rod connects one of the die blocks for moving it into operative compression relative to the other die block, the ring forming concentric channels in the pipes, a peripheral seal therebetween, a bead in one pipe nested within a channel of the other pipe, the ring being nested and interlocked within one channel. A pipe shear has a pair of aligned pivotally connected shear die blocks which replace the swedge die blocks, the shear blocks having opposed semi-circular recesses for securing a pipe therebetween when the shear die blocks are drawn together. An elongated shear blade is interposed between the piston rod and one of the die blocks and is guidably received by the die blocks. Compressive movement of the piston rod advances the shear blade through the pipe. |
