The connecting rods comprise large tile connecting rods 16 and small tile connecting rods 14, the tire shoulder brace blocks comprise large tire shoulder brace blocks 17 and small tire shoulder brace blocks 10, the large tile connecting rods 16 are connected with the large tire shoulder brace blocks 17, and the small tile connecting rods 14 are connected with the small tire shoulder brace blocks 10; the steel ring locking block 11 is fixedly connected with the locking slide block 7 along the radial inner side of the main shaft, a positioning groove is formed in the radial inner side of the steel ring locking block 11, the rubber ring 12 is annular, and the rubber ring 12 surrounds the periphery of the steel ring locking block 11 of the side drum and is connected with the steel ring locking block 11 through the positioning groove of the steel ring locking block 11; the thickness of the center of the rubber ring 12 is smaller than the thickness of the two sides; a semicircular groove 18 is formed in the inner side of the rubber ring 12; the device also comprises a cylinder body 2, a cylinder cover 6, a capsule seat 8, a capsule pressure plate 9 and a connecting pin 13.
The left side drum and the right side drum are respectively arranged on a main shaft of the forming machine through 13 connecting pins, and a ball screw is arranged in the main shaft of the forming machine, so that the left side drum and the right side drum can axially move. The air supply is lifted to the side drum by the main shaft to realize the expansion and contraction of each part. When the tire body cylinder moves to the center of the bladder turn-up forming drum, the tire shoulder pressing device fixes the tire shoulder of the tire body cylinder, specifically, the tire shoulder cylinder chamber is inflated, and the head end of the tire shoulder cylinder rod 5 moves forwards under the action of compressed air. The tire shoulder air cylinder rod 5 is connected with a small tile tire shoulder brace 10 through a small tile connecting rod 14 and is connected with a large tile tire shoulder brace 17 through a large tile connecting rod 16. Under the action of the tire shoulder air cylinder rod 5 and the large and small tile connecting rods, the large and small tile tire shoulder support blocks move in the radial direction.
