Problems solved by technology

[0002] At present, some minor injuries to all-steel radial heavy-duty tires can be repaired and continued to be used, but for major injuries such as crown bursts and punctures, the existing technology cannot repair them, and they can only be disposed of as waste tires
It not only shortens the service life of tires, but also increases the cost of replacing new tires for users, and waste tires have long been listed as a source of "black pollution" due to environmental pollution.

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] As shown in the figure, the radial tire crown burst repair is carried out as follows:

[0022] a. Along the circumference, near the sidewall of the tire shoulder edges, the crown surface 1 containing two layers of belt layer steel wire 3 is integrally cut away from the carcass 6 with a cutter;

[0023] b. Pick out the two layers of belt steel wires 3 with two broken ends 2 damaged at the wound on the crown surface 1, and then remove the explosion-proof belt steel wires 4 arranged along the circumferential direction of the crown near the tire shoulders, Cut off and reject according to the length of the belt layer steel wire 3 that has been removed;

[0024] c. After grinding the crown surface 1 as a whole, use the connecting rivet 5 to connect the two broken ends 2 at the wound of the crown surface 1 according to the original burst shape, apply...

Abstract

The invention relates to a radial tire crown burst repair method. The steps are: cutting the crown surface as a whole along the circumference to separate from the carcass; The crown surface is polished as a whole, and the two broken ends of the crown surface are butted according to the original burst shape with rivets. Angle, cross-lay in turn, and compact; remove the damaged belt steel wire on the carcass, polish the carcass surface evenly, coat the glue, and dry it; area and angle, add a new belt layer steel wire, and then spread a layer of raw film on the entire carcass; put the crown surface on the carcass, stagger the positions of the two wounds, and then paste the wound on the inner side of the carcass Patches; vulcanized molding on a vulcanizing machine. The various performances of the repaired tires of the invention meet the service requirements, and the service life of the tires is improved.

Description

Technical field: [0001] The invention relates to a tire repair method, in particular to a radial tire crown burst repair method. Background technique: [0002] At present, some minor injuries to all-steel wire radial heavy-duty tires can be simply repaired and continued to be used. However, for major injuries such as crown bursts and punctures, the existing technology cannot repair them and can only be disposed of as waste tires. It not only shortens the service life of tires, but also increases the cost of replacing new tires for users, and waste tires have long been listed as a source of "black pollution" due to environmental pollution. Invention content: [0003] The technical problem to be solved by the present invention is to provide a method for repairing radial tire crown bursts, which can repair crown bursts and punctures so as to meet the conditions for continuous use and prolong the service life of tires. [0004] The technical solution adopted by the present in...
