Abstract
The exposed cord in tyre cavity method for repairing and mending of a kind of tubeless finished product cover tire, comprises the following steps: first, the position subsidy film need to repaired because of exposed cord in tyre cavity by finished product cover tire；Secondly, utilizing the curing bag working cylinder urceolus of tire air forming machine, first capsule entirety is inserted in cylinder urceolus, while filling wind in capsule, capsule shaping machine central authority declines, and capsule is successfully drawn in the cavity of finished product cover tire；Then, finished product cover tire is reinstalled vulcanizing tank and uses intrinsic pressure water curing, make tyre cavity repair position pitted skin effect and reach the effect of normal finished product cover tire.Capsule can be reinstalled in cover tire cavity by the present invention, reinstall vulcanizing tank and use intrinsic pressure water curing, solve capsule return cover tire cavity secondary and reset the difficult points such as difficulty, cover tire trade mark, the easy ghost image of font, the pitted skin effect reaching tyre cavity defect mending position is the least with surrounding contrast, pitted skin, air draft line are respond well, the effect that user accepts.
Description
Technical field
The invention belongs to tyre production technical field, particularly relate to the method for repairing and mending of a kind of finished tire.
Background technology
For a long time, the technology that oblique finished product cover tire shapes with polishing tool polishing after repairing and using subsidy film electrical heating or return sulfurizing pot vulcanization.In recent years, for increasing the inducing QI of curing bag, curing bag model had all carried out pitted skin process；Nearest 2 years, capsule shaping sulfuration engineering tire specification yield increases sharply, the most all pitted skins of capsule surface, once there is tyre cavity discounting naked wire defect in finished product cover tire, existing repairing technique can not realize pitted skin effect, rejected region after repairing has a long way to go with normal portions apparent visual, and client is difficult to accept, and causes a large amount of engineering giant embryo unsalable.
We once attempted following method for repairing and mending: method one: use radial-ply tyre repairing technique, sent a 26.5-25 exposed cord in tyre cavity cover tire radial-ply tyre specialty personnel that dispatch workers to do on-site repairs to repair.Effect: making the ripe film of tyre cavity pitted skin and bubble always, a week does not fixes.
Method two: little area does pitted skin rubber moulding, uses many plates to vulcanize.Difficult point: tyre cavity Internal periphery radian position pressurization difficulty, seamless connection difficulty between plate and edges of boards edge, repair wind line effect difficulty.Effect: pitted skin effect is preferable, and air draft line effect is undesirable, inefficient.
Method three: after position subsidy film repaired by cover tire, capsule is reinstalled in cover tire cavity, reinstalls vulcanizing tank and use intrinsic pressure water curing.Difficult point: capsule returns cover tire cavity secondary and resets difficulty, returns tank and plays intrinsic pressure sulfuration, the easy ghost image of cover tire trade mark, font, the difficulty alignment of row interior lines.
Summary of the invention
The technical problem to be solved is to use for reference the advantage of tradition curing bag sizing, captures capsule and returns the difficult point that cover tire cavity secondary resets, thus provides the exposed cord in tyre cavity method for repairing and mending of the tubeless finished product cover tire of a kind of innovation.
In order to solve the problems referred to above by the following technical solutions: the exposed cord in tyre cavity method for repairing and mending of a kind of tubeless finished product cover tire, comprise the following steps: first, the position subsidy film that finished product cover tire need to be repaired because of exposed cord in tyre cavity；Secondly, utilizing the curing bag working cylinder urceolus of tire air forming machine, first capsule entirety is inserted in cylinder urceolus, while filling wind in capsule, capsule shaping machine central authority declines, and capsule is successfully drawn in the cavity of finished product cover tire；Then, finished product cover tire is reinstalled vulcanizing tank and uses intrinsic pressure water curing, make tyre cavity repair position pitted skin effect and reach the effect of normal finished product cover tire.
Described intrinsic pressure water curing, sulfide stress 2.9 ± 0.2Mpa, temperature 165-180 DEG C.
Capsule can be reinstalled in cover tire cavity by the present invention, reinstall vulcanizing tank and use intrinsic pressure water curing, solve capsule return cover tire cavity secondary and reset the difficult points such as difficulty, cover tire trade mark, the easy ghost image of font, the pitted skin effect reaching tyre cavity defect mending position is the least with surrounding contrast, pitted skin, air draft line are respond well, the effect that user accepts.
Detailed description of the invention
A kind of exposed cord in tyre cavity method for repairing and mending of tubeless finished product cover tire, comprise the following steps: first, the position subsidy film need to repaired because of exposed cord in tyre cavity by finished product cover tire, subsidy film is identical with the fluid sealant that finished product cover tire uses, and is mainly composed of rubber master batch, sulfur, altax, Vulcanization accelerator TMTD；Secondly, utilizing the curing bag working cylinder urceolus of waste and old LDK tire air forming machine, first capsule entirety is inserted in cylinder urceolus, while filling wind in capsule, capsule shaping machine central authority declines, and capsule is successfully drawn in the cavity of finished product cover tire；Then, finished product cover tire is reinstalled vulcanizing tank and uses intrinsic pressure water curing, make tyre cavity repair position pitted skin effect and reach the effect of normal finished product cover tire.Described intrinsic pressure water curing, sulfide stress 2.9 ± 0.2Mpa, temperature 165-180 DEG C.
Claims (2)
1. an exposed cord in tyre cavity method for repairing and mending for tubeless finished product cover tire, comprises the following steps: first, the position subsidy film need to repaired because of exposed cord in tyre cavity by finished product cover tire;It is characterized in that: secondly, utilize the curing bag working cylinder urceolus of tire air forming machine, first capsule entirety is inserted in cylinder urceolus, while filling wind in capsule, capsule shaping machine central authority declines, and capsule is successfully drawn in the cavity of finished product cover tire;Then, finished product cover tire is reinstalled vulcanizing tank and uses intrinsic pressure water curing, make tyre cavity repair position pitted skin effect and reach the effect of normal finished product cover tire.
The exposed cord in tyre cavity method for repairing and mending of tubeless finished product cover tire the most according to claim 1, is characterized in that: described intrinsic pressure water curing, sulfide stress 2. 9 scholar 0. 2Mpa, temperature 165-180 DEG C.
