Detailed Description
Example (b):
as shown in fig. 1 to 4, a novel tire building machine belted layer drum comprises a central cylindrical support 1 and a cylindrical belted layer drum body fixed on the support 1, wherein the belted layer drum body is formed by splicing a plurality of drum plates 2 with fan-shaped sections, a plurality of magnetic buttons 21 are fixedly embedded in the middle of the drum plates 2, the magnetic buttons 21 can firmly adsorb the lower surface of the belted layer when the belted layer is spliced, the displacement is generated without being influenced by the rotation of the belted layer drum and the shape of cushion rubber when the belted layer is spliced, and the accurate splicing and positioning are realized.
Be close to both ends position symmetry on the drum board 2 and be equipped with constant head tank 22, constant head tank 22 medial surface is the inclined plane, and its contained angle alpha with the constant head tank 22 bottom surface is 135, the constant head tank 22 medial surface is close to drum board 2 central point and puts, constant head tank 22 lateral surface is vertical face, and its contained angle beta with the constant head tank 22 bottom surface is 100, be equipped with several exhaust hole 23 on the constant head tank 22 medial surface, be equipped with a plurality of circular recesses on the constant head tank 22 bottom surface, the circular recess is embedded to have ball 24 that can freely rotate, ball 24 top exceeds constant head tank 22 bottom surface, drum board 2 both ends are equipped with locating pin 25 to fix on support 1 through locating pin 25.
A method of tire building using a novel tire building machine belt drum comprising the steps of:
1) carcass drum operation: sequentially attaching a tire side, an inner liner, a reinforcing layer and a tire body, and then transferring a tire bead and a locking ring to obtain a tire body cylinder composite part;
2) belt drum operation: the cushion rubber, the first belted layer, the second belted layer, the third belted layer, the zero belted layer and the tire surface are sequentially attached to form a tire crown composite part, then the tire crown composite part is pressed, the cushion rubber is arranged in the positioning groove 22, the positioning groove 22 can realize accurate positioning when the cushion rubber is attached to a belted layer drum, and the exhaust hole 23 formed in the inner side face of the positioning groove 22 is communicated with outside air and used for exhausting in the pressing process, so that the problem that air is stored in the pressing process to cause bad bubbles at the crown part can be avoided. The ball 24 embedded in the bottom surface of the positioning groove 22 can rotate freely, so that the non-stretching guiding positioning during the pad glue fitting is facilitated; the design of constant head tank 22 makes the pad glue laminating in-process can not receive the local unusual stretching that the friction leads to, and can go on along with the laminating, and the whole stop in standard location department of the pad glue freedom stability, and the location is accurate. Through calibration, the cushion rubber is subjected to little external acting force, and is stretched by only 3 per thousand, so that the stretching force can be ignored.
