Abstract

The invention relates to a device and method used for bead locating and turning up of an aviation radial tire building machine. The device comprises a tire body drum, a right angle forming unit, a left turning up unit and a right turning up unit; the tire body drum is arranged on a spindle, and can rotate along with the spindle; the right angle forming unit is used for pressing a carcass ply intoa right-angle structure by hooping when the tire body drum expands; the left turning up unit is arranged at the left side of the tire body drum, and comprises a left turning up bladder and a left turning up assembly; the left turning up bladder is arranged on a spindle between the left side of the tire body drum and the left turning up assembly; the left turning up assembly can be axially and movably arranged on a spindle at the left side of the tire body drum, and is used for installing a tire bead into the carcass ply in a turning up manner when the left turning up bladder is inflated to expand; the right turning up unit and the left turning up unit are symmetrically arranged at the right side of the tire body drum; and a right turning up assembly can be axially and movably arranged on aspindle at the right side of the tire body drum, and is used for installing the tire bead into the carcass ply in a turning up manner when a right turning up bladder is inflated to expand.

Description

technical field [0001] The invention relates to the technical field of aviation manufacturing, in particular to a buckle turn-up device and method 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 direction of the carcass drum axis 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...
