The steel ring is also called a wheel hub, and an automatic laminating device is required for extrusion lamination in the process of apex strip laminating.

[0003] The existing automatic apex strip laminating device performs vertical lamination, that is, the angle between the bottom surface of the apex strip and the vertical plane is 90° when the apex strip is laminated. Since the apex strip lamination of an aircraft tire requires a lamination angle of 65° - 75°, and the existing automatic apex strip laminating device cannot achieve this, it is urgent to develop an apex strip applying device that can achieve lamination at different angles.

The outer side of the inner support block is connected to the inclined support block. The height of the inclined support block is the same as the height of the bottom of the support groove. The included angle between the inclined surface of the inclined support block and the horizontal plane is 15° - 25°, and the inclined support block is used to support the apex strip.

[0006] Furthermore, it also includes a fixed disc. Six sliding grooves are provided on the fixed disc, and the six sliding grooves are evenly arranged radially with the center of the fixed disc as the center. A cylinder is fixedly provided on one side of the sliding groove close to the center of the fixed disc. The telescopic end of the cylinder is connected to a sliding plate, and the sliding plate is slidably connected to the side wall of the sliding groove. The support ring disc is located above the fixed disc, and the centers of the support ring disc and the fixed disc are on the same central axis.

[0019] As Figures 1 to 4 shown, a chafer applying support ring disc includes a support ring disc 1 and a fixed disc 2. The support ring disc 1 is an annular disc surrounded by six arc-shaped support ring blocks 11. There is a certain gap 12 between adjacent two support ring blocks 11. The support ring block 11 includes an inner support block 111 and an inclined support block 112. On the outer side of the top of the inner support block 111, there is a support groove 113 for supporting the steel ring 3. The outer side of the inner support block 111 is detachably connected to the inclined support block 112. There are two countersunk head bolts 114 on the top of the inner support block 111. The height of the inclined support block 112 is the same as the bottom height of the support groove 113. The included angle between the inclined surface of the inclined support block 112 and the horizontal plane is α, and α = 20°. The inclined support block 112 is used to support the chafer 4.

[0020] The fixed disk 2 is provided with six sliding grooves 21, and the six sliding grooves 21 are radially and uniformly arranged around the center of the fixed disk 2. A cylinder 22 is fixedly arranged on one side of the sliding groove 21 close to the center of the fixed disk 2. The telescopic end of the cylinder 22 is connected with a sliding plate 23, and the sliding plate 23 is slidably connected with the side wall of the sliding groove 21. The support ring plate 1 is located above the fixed disk 2, and the centers of the support ring plate 1 and the fixed disk 2 are on the same central axis. The countersunk head bolt 114 is threadedly connected with the sliding plate 23.

[0021] Preferably in this embodiment, the arc angle of the support ring block 11 is β, and β = 57°.

[0022] Preferably in this embodiment, the width of the support groove 113 is L1, and the radius of the steel ring 3 is R, where L1∶R = 11∶8.5.
