Problems solved by technology

However, for radial tires, it is useless to add a ferrule made of skeleton material without removing the damaged belt layer, because the damaged belt layers will rub against each other and generate heat during driving, causing tire blowout accident

Embodiment 1

[0018] Embodiment 1, the carcass that has use value and the steel wire radial tire that the belt layer is damaged carry out reinforcement restoration, main method and step of the present invention are: 1, as shown in the accompanying drawing, start from tire tread 1 side According to the peeling position 3, cut between the tire carcass steel wire 5 and the belt layer 2, and stick to the belt layer 2, and peel off the worn tread 1 together with the belt layer 2, and the peeled off It is a ring-shaped tread; 2. Grinding the joint surface peeled off by the carcass 4; 3. Brushing the glue on the joint surface; 4. Applying adhesive glue; 5. Pre-vulcanized annular tire with belt layer 6. Carry out pressing, so that the carcass 4 and the precured annular tread containing the belt layer are combined well; 7. Put the pressed tire into the envelope, and put the vulcanized inner tube in the tire, and put it in the Vulcanized rim; 8. Put it into the vulcanization tank for vulcanization; 9...

Embodiment 2

[0019] Embodiment 2, the carcass that has use value and the steel wire radial tire that the belt layer is damaged is strengthened and restored, the main method and step of the present invention are: 1, as shown in the accompanying drawing, start from tire tread 1 side According to the peeling position 3, cut between the tire carcass steel wire 5 and the belt layer 2, and stick to the belt layer 2, and peel off the worn tread 1 together with the belt layer 2, and the peeled off It is a ring-shaped tread; 2. Grinding the combined surface of the carcass 4; 3. Brushing the glue on the combined surface; 4. Applying adhesive glue; 5. According to the belt layer material and specification of the original tire , Cord arrangement angle, number of layers blanking, sticking on the carcass 4 layer by layer, can also improve the belt layer of the original tire, such as changing the cord specification, arrangement angle, form, number of layers, etc.; 6, Apply adhesive glue on the belt layer...

Embodiment 3

[0020] Embodiment 3, the carcass is better and the steel wire radial tire of belt ply local damage is lighter is strengthened and refurbished, main method and step of the present invention are: 1, polish off old tread 1 on tire grinding machine; 2 1. Peel off the damaged belt layer 2; 3. Grind the stripped surface; 4. Apply glue; 5. Apply adhesive glue; 7. Brush glue on the whole tire grinding surface; 8. Apply adhesive glue; 9. Paste pre-vulcanized strip tread or set pre-vulcanized annular tread; 10. Press 11. Put the pressed tire into the enveloping sleeve, and put the vulcanized inner tube into the tire. On the vulcanized rim; 12. Put it into the vulcanization tank for vulcanization; 13. Finish. Complete the intensive reconditioning process of used tires.

[0021] In the above embodiments, if the vulcanization mold is used for vulcanization, the enveloping sleeve and the vulcanized rim are not used.

Abstract

The invention relates to a method for strengthening and revamping a radial ply tire. The method is used for strengthening and revamping a steel wire radial ply tire which has fetal body with useful value and damaged stabilizer ply. The method includes: 1, the steel wire 5 of the fetal body of the tire and the stabilizer ply 2 are cut off according to a peeling off position 3 from the side face of the tire tread 1 of the tire, the worn out tire tread 1 which is clung below the stabilizer ply 2 is peeled off along with the stabilizer ply; 2, the junction surface where the fetal body 4 is peeled is polished; 3, plasmagel is painted on the junction surface; 4, bonding glue is applied; 5, a precure tire tread is sheathed; 6, stitching is carried out, thus the tire tread 4, the stabilizer ply 2 and the annular precure tire tread are well combined; 7, the tire is packed into an outer envelope after the stitching, a vulcanized inner tube is loaded in the tire, then the tire is put on a vulcanizing wheel felloe; 8 the tire is vulcanized in a vulcanizing tank; 9, finishing. By the method, the worn out tire can be strengthened and revamped.

Description

technical field [0001] The invention relates to a method for strengthening and renewing a radial tire, and belongs to the technical field of tire retreading and reuse of old tire resources. Background technique [0002] With the continuous rapid growth of car ownership in today's world, the consumption of tires has increased sharply. In order to save resources, tire retreading has become an important way of environmental protection, energy saving and emission reduction that countries all over the world are developing. However, traffic accidents caused by retreaded tires abound, which is worrying. There is a great contradiction between resource saving and driving safety and reliability, which also hinders the development of tire retreading. [0003] The current various tire retreading technologies such as traditional retreading method, prevulcanized strip tread and annular tread retreading method are to polish old tires, apply glue on the surface, paste tread rubber or prevul...
