Abstract
PURPOSE: To surely prevent generation of the shape defect, and to make the following process possible to be abbreviated, by filling the interior of the bending part with the hard granule and the water, and by applying the bending work.
CONSTITUTION: A specified amount of the hard granule is put into the pipe blank P and the water is poured into the pipe blank P as much as the packed granule is completely submerged in the water, and again the granule and water are filled in this order similarly to above procedure; this procedure is several times repeated with the amount of granule and water divided into number of repetitions; as a result, whole interior of the pipe blank P is filled up with the granule and the water fills up every space formed among the granules, and hereby, the air is perfectly excluded from the interior of the pipe blank P. The hard granule as the packing material is prepared by mixing the sand, the steel ball or crushed steel ball at a suitable proportion. Next, the pipe blank P is laid to bridge the holding grooves 11, 11, of the loading beds 1, 1, on both sides, so as to locate the longitudinal center of the bending part C of the pipe blank P at the position just under the bending roll 2, that is at the middle of the bearing shafts 12, 12, of two loading beds 1, 1. Then, the bending roll 2 is brought down to make the pushing groove 21 to ride on and touch the pipe blank P, and the bending work is performed.
