An example is a longitudinal side view showing the upper half when the diameter is reduced and the lower half when the diameter is enlarged. In Figure 2, the upper half is a view taken along line A in Figure 1, and the lower half is B in Figure 1. 3 is a sectional view of the holder, FIGS. 4 and 5 are a front view and a plan view of the holder, respectively, FIG. 6 is a sectional view of the stopper, and FIG. 7 is a sectional view of the holder.
It is a sectional view taken along the line CC in the figure. In the figure, 12 is a drum shaft, 18 is a drum segment, 19
is a drum shell, -20 is an air cylinder mechanism, 22 is a cylinder tube, 23 is a piston, 40 is a link mechanism,
50 is a connecting pin, 52 is a slide y-rond, 60 is a slide rond forward position regulating mechanism, 61 is a holder, 62.
63, 64 and 66' are respectively the hole part of the holder, the bottom wall,
An opening, a pin hole, 69 is a spring, 70 is a connecting pin, 72 is a stopper, 73, 75, and 76 are a stopper hole, a deformed flange, and a pin hole, respectively.

置。An arc-shaped drum shell is fixed to multiple drum segments arranged radially around the drum shaft, and an air cylinder mechanism arranged concentrically with the drum shaft moves the drum segments in the radial direction via a link mechanism. In a forming drum in which the diameter of the drum shell is expanded or contracted by sliding,
A slide iron slidable in the direction of the drum axis is fitted inside the drum shaft, and the slide iron is connected to a sliding member of either the cylinder tube or the piston of the air cylinder mechanism by a connecting member. The insertion hole of the slide rond is open at one end, and a stopper has an irregularly shaped flange having a pin hole attached to the opening end, and a hole into which the irregularly shaped flange of the stopper can be fitted; A holder is provided with an opening in the bottom wall into which the irregularly shaped flange of the stopper can be inserted, and a pin located on the circumference having the same radius as the pin hole of the stopper, and the holder is inserted into the pin hole of the holder while being biased in the insertion direction. The holder is fixed to the fixing member on the tip end side of the drum shaft, and the holder is inserted through the opening of the holder and fitted into the hole, and the slide rond is moved forward. The stopper, whose tip was slidably inserted, was fixed by inserting a connecting pin with the pin hole of the irregular flange aligned with the pin hole of the first holder, and the stopper was held in the holder in a detachable manner. A device for changing the diameter of a forming drum.
