Abstract

PURPOSE:To improve the dimension accuracy of an object to be worked, by setting a distance between 2 shafts of a pair of rolls, when executing roughing- down by working of a lot of passes. CONSTITUTION:A titled device is constituted to vary distances d2-d5 between 2 shafts of forging rolls 3, 4 and an optimum rolling reduction can be obtained by each pass by setting these distances d2-d5 at every pass. Also, it is constituted to vary bite start positions l2-l5 of a roll by a manipulator 5 and these positions l2-l5 are set at every pass to produce an optimum bite position of each pass.

する。No. 5 lIlK As shown, one forging roll 4
is capable of moving forward and backward with respect to the other forging roll 3. That is, a flaw ring 7 is rotatably interposed 4E between the four shaft ends of the forging roll 4 and the bearing part 6, and by rotating this eccentric ring 7, the forging roll 4 becomes the forging roll S. advance and retreat against As shown in body 5E, in the eccentric ring 7, the shaft end 4m is eccentrically inserted into the seven ring bodies through the sleeve 8, and the outer peripheral part of the seven ring bodies is inserted into the bearing part 6 through the sleeve 9. It is freely supported through. Further, a flange portion 718 is formed on the seven ring bodies, and a gear 1o is formed on the outer periphery of this flange portion 7B.
The pinion 11 is engaged with the pinion 11, and by rotating the pinion 11 with the pinion 11 by an appropriate means, the eccentric ring 7 is completely rotated.

第４ＩＩｌｉに示すように、このピニオン１１は。As shown in No. 4 IIli, this pinion 11 is.
