Abstract

PURPOSE:To obtain a pipe which is further longer than the caliber of rolls in a cold Pilger mill used in production of short-sized tapered pipes, by making the feed adjustment of the work possible and rolling the work repeatedly. CONSTITUTION:The work 18 is inserted between the tapered part 19a of a mandrel 19 and a roll caliber 15. Next, the upper, lower rolls 11, 12 of a roll stand 2 are rolled to roll the leading end part of the work 18, whereby a tapered pipe part corresponding to the length of the caliber 15 is made. After the end of this first rolling, a chuch 22 for the work, a rack 8 and a chuck 20 for mandrel are moved forward while the stand 2 is held fixed, so that the work 18 and the mandrel 19 are fed. Thence, the angle of the caliber 15 is changed, and the work 18 is again rolled in the same manner as that in the first time. The above- mentioned rolling operations are repeated until the long-sized pipe is obtained.
