とができる。FIG. 3 shows an example of a position adjustment mechanism for each of the support rollers 3, 6 and the tilting head 4. As shown in FIG. In the figure, 7 is an electric motor (or other device that generates rotational force), 8 is a horizontal bed 2
shafts 9 and 10 supported by bearings and rotated by the electric motor 7;
11 is a female thread fixed to the support roller 3 and fitted to the threaded part 9; 12 is a female thread fixed to the inclined bed 4 and fitted to the threaded part 10; 13 is a gear that moves together with the tilting bed 4 and transmits rotation to the shaft 15 attached to the tilting throat 1 through the gear 14; 16.17 is a threaded portion of the shaft 15; 18
．． 19 is fixed to the support roller 6 and has a threaded portion 16.
This is a screw fitted into 17. When the shaft 8 is rotated by the rolling machine 7 or input, the threaded portion 9 provided on the shaft 8,
10, the support roller 3 and the inclined bed 4 are slid in the direction of the arrow shown in the figure, respectively, via an internal thread 11 fixed to the supporting roller 3 and an internal screw thread fixed to the inclined bed 4. Rotation is also applied to the shaft 15 of the tilting bed 4 through gears 13, 14, and the shaft 15 is fixed to the support roller 6 through a threaded portion 16, 17 and is connected to the support roller 6 through an internal thread 18, 19, respectively. It is slid in the direction of the arrow. Therefore, if the pitch of the threaded portions 9, 10° 16.17 and the reduction ratio of the left and right gears 13° 14 are properly determined, even if the diameter of the cylindrical shell l varies, the shaft 8 Constant support angles θ^, θS, UC can be obtained by simply rotating the cylindrical shell 1, and each support roller 3, 6 circumscribes the cylindrical shell 1 in a correct circular arc to support it and rotate the cylindrical shell 1. can. Although FIG. 3 shows a case in which all position adjustments are made simultaneously, it is also possible to make them individually or only in part. - According to such a configuration, the outermost support angle θC can be made wider than before in terms of structure, so the bending moment in the cross-sectional direction due to the weight of the cylindrical shell is reduced, and the number of support rollers is increased, so the support point The reaction force at is also reduced.・
In addition, the maximum stress at the support point of the cylindrical shell is significantly reduced compared to the conventional 20-roll rotating jig, making it easy to accommodate changes in the diameter of the cylindrical shell even with a large number of supporting rollers. You can do it.
