Embodiment Construction
[0025] Below in conjunction with embodiment, to the embodiment, feature and effect thereof of the semi-steel wire radial tubeless tire three-side repair process and equipment proposed according to the present invention, detailed description is as follows.
[0026] Such as Figure 3-5 The process of repairing semi-steel radial tubeless tires at fixed time and temperature on three sides: grinding the tire sidewall wound 3; grinding the inner surface of the tire. Crown and belt layer 4; After grinding, apply glue on the grinding place, paste the skeleton material and rubber material 2, put the glued tire on the semi-steel radial tubeless tire three-side repair equipment, pressurize, heat and vulcanize, glue material, skeleton The material and the original carcass become a whole, and the process is completed after the excess glue is modified, and the rubber material, the skeleton material and the original carcass become a whole.
[0027] Such as figure 1 , figure 2 , three-sid...

The invention discloses a three-surface repairing process and a three-surface repairing equipment for a semi-wire radial tubeless tire. The process flow comprises the steps of: polishing an external wound of a tire; polishing the internal surface of the tire, wherein the internal polishing range is from a toe mouth of the tire, the side of the tire to the cap belt of the tire according to the radial arrangement of the original tire body; after polishing, brushing adhesive cement on the polished parts and enabling the polished parts to be adhesive; putting the adhesive tire on the three-surface semi-wire radial tubeless tire repairing equipment to be pressurized, heated and vulcanized; and after vulcanization, removing the residual adhesive so that the working procedures are completed. Thethree-surface tire repairing equipment is mainly characterized in that the tire is heated and pressurized in the three directions of the toe mouth, the side of the tire and the cap belt of the tire so as to ensure the framework material, the tire body and the adhesive to be pressed and heated uniformly, thus the repaired part is flat without bubbles and can be attached on the tire body firmly.
Description
technical field [0001] The invention relates to tire repair technology, in particular to a process and equipment for repairing semi-steel wire radial tubeless tires on three sides at fixed time and temperature. Background technique [0002] There are two methods for traditional semi-steel wire radial tire repair: one is the cold repair method, that is, using pre-vulcanized film and neoprene glue for bonding; Repair in a suitable way. The two methods have their own advantages and disadvantages. The first method is easy to operate and low in cost, but it can only repair small nail holes in the tire crown; the second method can repair tire sidewall wounds, and its cost and operation difficulty are higher than The cold patching method, durability and airtightness are not long-lasting, and cannot meet the high airtightness and flexibility requirements of semi-steel radial tubeless tires, especially the driving safety is poor. It can be scrapped directly, which does not meet the...
