Carcass barrel forming device and carcass barrel forming process for aviation radial tires

Abstract

The present invention provides a molding device for aeronautical radial tire carcass tubes, which includes a main shaft, the main shaft is externally connected with a driving force to rotate; The outer surface of the carcass cord is pasted with the carcass drum, and the two sides of the carcass drum are respectively provided with a first turn-up unit and a second turn-up unit; the first turn-up unit or the second turn-up unit includes The turn-up airbag and moving component of the body cord, the turn-up airbag is set between the moving component and the carcass drum; the moving component is set on the main shaft, and makes a linear movement close to or away from the carcass drum synchronously with the rotation of the main shaft; through When the carcass drum is inflated, the pressing assembly presses the carcass cord along the radial end of the carcass drum into a right-angle shape, and the booster wraps the bead on the carcass when the turn-up air bag is inflated. In the cord, it solves the problem of rubber pleating at the root of the bead of the carcass tube of the aviation radial tire, and realizes the automatic forming of the carcass tube.

Description

technical field [0001] The invention relates to the technical field of aviation manufacturing, in particular to a carcass tube forming device and a carcass tube forming process for aviation radial tires. 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 to fit the carcass drum, and the carcass cord material on both sides of the carcass drum is shrunk by the wrapping device to be smaller than the diameter of the bead. , the bead is put 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 between the carcass cord of the aviation radial tire and the axis of the carcass drum is 3 to 5 degrees), the number of bonding layers is large (one-time bonding) Generally, 6 to 8 layers of in...
