Abstract

The invention relates to a tire case drum right angle shrinkage device for an aircraft radial tire building machine. The tire case drum right angle shrinkage device comprises a left ring body and a right ring body which are connected through ring body connecting rods. The radial surface of the left ring body and the radial surface of the right ring body are each provided with a plurality of side pressing blocks distributed circumferentially. The circumference of the side pressing blocks are concentric with the corresponding ring body. The side pressing blocks can conduct synchronous radial expansion on the corresponding left ring body and the corresponding right ring body so that the diameters of the circumferences formed by the side pressing blocks are changeable. The tire case drum rightangle shrinkage device is used for pressing tire case cord fabrics to the right-angle end of a tire case drum after all the side pressing blocks on the two ring bodies conduct synchronous shrinkage when the tire case drum is attached to the tire case cord fabrics. When the tire case drum expands in the radial direction, the tire case cord fabrics is wrapped outside the right-angle end of the tirecase drum in a right-angle mode.

Description

technical field [0001] The invention relates to the technical field of aviation manufacturing, in particular to a carcass tube retracting right-angle device for an aviation radial tire building machine. Background technique [0002] The carcass tube forming method of the existing aviation bias tire is that the carcass cord is expanded to be larger than the diameter of the bead in the carcass drum to fit, and the carcass cord material on both sides of the carcass drum is shrunk by the positive wrapping device to be smaller than the diameter of the bead Finally, the bead is placed on the buckle ring, and the turn-up capsule is inflated to complete the turn-up process. [0003] Since the angle of the carcass cord of the aviation radial tire is small relative to the cord of the aviation bias tire (the angle with the axis of the carcass drum is 3 to 5 degrees), the number of lamination layers is large (one lamination generally requires lamination of 6 to 8 layers) Inner liner ca...
