Problems solved by technology

[0002] At present, in the tire repair shop in the society, there are mainly two methods to deal with the hard damage on the side of the tire: one is the cold patch plus reinforcement method, this method only reinforces and seals the inner side of the wound, and the outer side of the wound cannot be effectively treated , foreign matter and dust will enter the wound and cause the patch to gradually fall off
The second is the rubber thermal vulcanization method. After the rubber on the damaged part of the sidewall is polished, new raw rubber is filled, and the local vulcanizer is used to heat and pressurize the wound. After the wound is cooled, the cold patch is used inside the wound. Reinforcement, which solves the problem of foreign matter and dust intrusion, but the inner cold patch is easy to fall off, resulting in loss of reinforcement and airtight effect, resulting in wound burst
This method needs to dig rectangles along the wound and suture them. The procedure is complicated and the wound area will be increased. 15mm, which is more suitable for long wounds, and the repair of irregular wounds such as arcs is limited; this method is only suitable for the treatment of sidewall wounds, and cannot repair tire top wounds
The repair method of CN10362670A is only suitable for the repair of tire shoulders and tire roofs, and the needle repair method of horizontal stitching and then vertical stitching is not suitable for repairing thinner sidewalls and has limitations.

Embodiment 1

[0031] Embodiment A pair of sidewall wound repair, the tire to be repaired is a truck tire that has been used for 1 year, the wound and the cord are at an angle of 85 degrees, and the length of the wound is 85mm.

[0032] The maximum safe repair wound size of the sidewall is 100mm along the vertical cord direction. If there is an angle between the wound and the cord, it shall be calculated based on the projected size of the wound in the vertical cord direction, but the actual repair size of the wound shall not exceed 150mm. .

[0033] Refer to attached figure 1 , this embodiment includes the following steps:

[0034] A. Tire expansion: remove the tire wound and the surrounding dust, oil and impurities, and use the tire expansion machine to open the broken part of the tire;

[0035] B. Grinding exposed lines: Grind the area on both sides of the fracture wound with a hand grinder. The grinding area is 15-25mm on both sides of the wound. Grind off all the rubber on both sides t...

Embodiment 2

[0043] The mending of embodiment two tire top wounds, the long 45mm of wounds

[0044] The maximum safe repair wound size of tire roof is 50mm along the broken line direction

[0045] The tire to be repaired is a 2.5-year-old car tire, the steel wire is not damaged, the wound is 35mm long and 10mm deep

[0046] The repairing method of this embodiment is basically the same as that of Embodiment 1, except that what is used in the "D, wiring" step is a multi-connection knotting method. The multi-knotting method refers to combining 2 or 3 broken thread ends on the same side of the wound by tying a dead knot, so that two rows of knots extending along the wound are formed on both sides of the wound, Each knot forms a knot loop, that is, the 2 or 3 broken threads that make up the knot are connected to form a closed knot loop, so that two rows of knots are formed on both sides of the wound. Head thread loop; take a new thread of sufficient length, tie one end of the new thread to th...

Embodiment 3

[0047] Example 3 Repair of sidewall wounds. The tire to be repaired is a truck tire that has been used for half a year. The wound and the cord form an angle of 30 degrees, and the length of the wound is 95 mm.

[0048] refer to figure 2 , The repairing method of this embodiment is basically the same as that of Embodiment 1, the difference is that what is used in the "D, wiring" step is the dislocation connection and knotting method. The dislocation connection knotting method is to stagger one or two broken thread ends on both sides of the wound to connect, and use a new thread to connect the first broken thread end on one side of the wound with the second or second thread end on the other side of the wound. The three broken thread ends are connected with a dead knot, and then the long end of the new thread is wound back to the wound on one side and connected with the second broken thread end, and then the long end of the new thread is wound to the other side of the wound and ...

Abstract

The invention discloses a repair method for tire holes, which belongs to the field of repair methods for tire holes. The repair method comprises the following steps of A, tire expanding; B, polishing and cord exposing; C, periphery polishing; D, cord connecting; E, skin laminating and material preparing; F, rubber heat vulcanization treatment and the like. The broken cords are firmly connected by adopting a cord connecting manner, and a crude rubber heat vulcanization internal and external repair technology is used for enabling the bearing capability, compressive strength and the like of a repaired tire to reach the level of an unimpaired tire and enabling surface appearance of the repaired tire to be recovered to the level which cannot be seen by naked eyes; the repair method is used for repairing holes in various shapes, is suitable for repair at tire top holes, tire sidewall holes and tire swells, and is flexible and simple in operation.
