Abstract
The invention discloses a tire hot retreading central air charging mechanism, which belongs to the technical field of waste material retreading of automobile tires. The mechanism is provided with a lifting shaft; the middle of the lifting shaft is provided with a stop pin fixing sleeve; the outer end of the stop pin fixing sleeve is sleeved with an air charging airbag; and the upper end of the lifting shaft is a guide post which is connected with the air charging airbag. As the invention adds the airbag and a mechanism for assisting the airbag on the basis of the existing product, the air charging pressure of the airbag can be utilized in tire hot retreading to lead the retreaded tire to have an internal even jacking force in the retreading process, thus leading the retreading to be more stable and reliable and the quality of processed product to be greatly improved. Therefore, the invention not only uses waste materials to create new social value and products being beneficial to environmental protection, but also leads the product quality to be better guaranteed; and the retreaded tire is as good as new products, thus guaranteeing the traffic safety.
Description
Technical field
The present invention relates to the old and useless article reconditioning technology field of tire for vehicles, a kind of specifically tire heat is turned over centre punch mechanism of qi structure.
Background technology
Tire, in use, especially in long-term running, can make its surperficial glue-line wearing and tearing with the friction on ground, after this situation causes that promptly the treadwear of the various groove decorative patterns in carcass surface arrives to a certain degree, decorative pattern can't guarantee effectively that wheel and ground produce enough friction, so vehicle easily skids under steam or braking distance is long, the security performance that serious reduction vehicle travels for this reason just must re-type.And outcast junked tire not only can pollute surrounding environment, but also can cause the huge waste of existing resource.
At present, mainly be by the retreading wear surface for the method for utilizing again of junked tire, its regeneration is used, so be referred to as tyre rebuilding.Existing domestic tire reconditioning technology mainly all is to adopt cold renovate method, and its technology is: the prevulcanization retreading tread rubber is fitted in through on the carcass of polishing, and by carrying out vulcanizing treatment at vulcanizing tank, reaches the purpose of retreads.
And external industrial advanced country renovates for equipment and technology that the renovation of tire has begun to adopt vertical heat to turn over.Introduce and digestion overseas equipment and technology, have one very important problem be that this equipment has a defective, the tire inner face that is promptly renovated in the course of the work lacks supporting, thereby can cause that the problems such as unstable product quality after the renovation occur.
Summary of the invention
Turn over the deficiency of equipment in order to overcome existing heat, the objective of the invention is on the basis of existing equipment, to propose a kind of tire heat and turn over centre punch mechanism of qi structure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of tire heat is turned over centre punch mechanism of qi structure, it is characterized in that: have one to stretch and fall axle, stretch the centre that falls axle and be provided with spacer pin and overlap surely, the outer end that spacer pin overlaps surely is with the qi of chong channel ascending adversely air bag; Stretching the upper end that falls axle is connected lead.
Described stretch axle size is fallen and can be according to the model that various correspondences are set by varying in size of retreads; Also can set a model, as long as the model that the limitation locking cover that change is provided with varies in size is carried out supporting use.
Described spacer pin overlap surely be two little cylindrical in the middle of big, it can select for use the air bag of different size to design width in the middle of it according to the size difference of tire, and the major part of two ends is as the displacement position-limiting of air bag.
Described fairlead is a cone, and its tapering is 1～10 degree.The cone size can be according to by the size of retreads, determines its model.
The middle passage that offers of axle falls in described stretching, and passage is connected with qi of chong channel ascending adversely air bag qi of chong channel ascending adversely mouth by the limitation locking cover.
Described air bag is the air bag of known high temperature resistant, pressurize.
This mechanism is installed in the center that existing tire heat is turned over machinery, adds supporting accordingly (structure and air compressor machine fall in known stretching), just can carry out work.
The invention has the beneficial effects as follows: because the present invention has added air bag and the attached mechanism that helps air bag work thereof on existing product basis, in hot tire recap, just can utilize like this qi of chong channel ascending adversely pressure of air bag make the tire that is renovated in refurbishment process, have in one even top power, thereby make its more stable work reliable, the product quality after the processing is improved widely.Therefore, the present invention is not only a kind of old and useless article that utilizes, and create new social value and the product that helps environmental protection, and the quality of its product is more guaranteed, and the product that turns over system has brought guarantee as new product to traffic safety.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is a topology view of the present invention.
1 stretches and falls axle, 2 limitation locking covers, 3 air bags, 4 leads among the figure.
The specific embodiment
Embodiment 1:
See also Fig. 1, have one to stretch and fall axle 1, stretch and fall axle 1 centre and be provided with spacer pin and overlap 2 surely, spacer pin overlaps 2 outer end surely and is with qi of chong channel ascending adversely air bag 3; Stretching the upper end that falls axle 1 is connected lead 4.
Claims (4)
1, a kind of tire heat is turned over centre punch mechanism of qi structure, it is characterized in that: have one to stretch and fall axle, stretch the centre that falls axle and be provided with spacer pin and overlap surely, the outer end that spacer pin overlaps surely is arranged with the qi of chong channel ascending adversely air bag; Stretching the upper end that falls axle is connected lead.
2, a kind of tire heat according to claim 1 is turned over centre punch mechanism of qi structure, it is characterized in that: described spacer pin overlap surely be two little cylindrical in the middle of big.
3, a kind of tire heat according to claim 1 is turned over centre punch mechanism of qi structure, it is characterized in that: described fairlead is a cone, and its tapering is 1～10 degree.
4, a kind of tire heat according to claim 1 is turned over centre punch mechanism of qi structure, it is characterized in that: the middle passage that offers of axle falls in described stretching, and passage is connected with qi of chong channel ascending adversely air bag qi of chong channel ascending adversely mouth by the limitation locking cover.
