Specific embodiment
Technical solution of the present invention is described in further detail below in conjunction with specific embodiments and the drawings.
Embodiment 1
As shown in Figure 1 to Figure 3, a kind of semi-steel radial tire adjustable diameter setting drum, including left side drum and right-hand drum, it is described
Left side is bulging and right-hand drum passes through axle sleeve 1 respectively and is mounted on the main shaft of molding machine, and the left side is bulging and right-hand drum is equipped with interior lead
To disk 2, outer positioning disk 3, cylinder power device and shrink-ring, the interior positioning disk 2 and outer positioning disk 3 are solid with the axle sleeve 1
Fixed connection, the cylinder power device include big cylinder chamber 4 and small cylinder chamber 5, and the periphery of the shrink-ring is equipped with tyre bead locking
Device 6, the tyre bead locking device 6 are annular groove, and the annular groove is equipped with cushion rubber 7, and the shrink-ring is by plural block
The equal and successively alternate crankshaft bearing bracer 8 of block number and small watt of bracer 9 are constituted, and the crankshaft bearing bracer 8 and small watt of bracer 9 are respectively and greatly
Sliding block 10 is fixedly connected with small slide block 11, and the big sliding block 10 and small slide block 11 are cut with scissors with crankshaft bearing connecting rod 12 and small watt of connecting rod 13 respectively
It connects, the crankshaft bearing connecting rod 12 and small watt of connecting rod 13 are connect with crankshaft bearing slide 14 and small watt of slide 15 respectively, and the axle sleeve is equipped with
Adjusting nut 16, the outer positioning disk 3 are equipped with gag lever post 18, and the gag lever post 18 passes through the outer positioning disk 3, the limit
One end of bar 18 is fixed on position-arresting disk 17, and gag lever post 18 is freely slidable by being clearance fit when outer positioning disk 3, and four
Gag lever post 18 supports position-arresting disk 17 as positioning action, and adjusting nut 16 is screwed on the screw thread of axle sleeve 1, by rotating the tune
Section nut 16 can limit the axial position of the position-arresting disk 17, so that position-arresting disk 17 drives gag lever post 18 to move axially；
