Abstract
A pipe bending tool has two indicators one at the upper surface between the shank and the bending finger and calibrated to determine the bending required for a given dimensional offset and the curved anvil bending surface for the tool also has calibration so that with the tool stationary the pipe can be bent around the curved anvil surface until the correct bending is effected for a given dimensional offset.
Claims2
The process for effecting offset bends in pipe and the like with a bending tool having an arcuate concaved anvil surface with pairs of predetermined stop location openings disposed angularly about said anvil, comprising the steps of inserting a cross member through a selected pair of aligned openings in the walls of the concaved anvil surface to form a stop and at an anvil location corresponding to the ratio of the offset to the distance between the respective bends, disposing the bending tool at a predetermined distance from the end of the pipe at the location where the first bend is to be effected, and with the bending tool and anvil in position, wrapping the pipe around the anvil until contacting said stop to perform a first bend, relocating the anvil to a second location on the pipe where reverse bending is to be performed determined by the value of said ratio and wrapping the pipe around the anvil until the pipe comes in contact with said stop to effect a combination of offset bending which is determinative of the ratio of the offset of the respective bends and the distance between said bends, and following the bending operation, reaming the end of the pipe or conduit with a reamer integral with the bending tool.
