Description
Technical field
The present invention relates to a kind of method for renovating tyre, especially a kind of capsule shaping and segmented mold vulcanized method for renovating tyre of method that twines belongs to the rubber tyre technical field.
Background technology
Tyre rebuilding is a kind of technology that old tire is repaired and reused, and is to realize the recycling a kind of fine approach of old resource comprehensive.At present the method for tyre rebuilding has heat to turn over cold to turn over two kinds, but no matter all there is following problem in which kind of method: (1) complex process, as presulfurization method tyre retreading technique, at first to carry out presulfurization to the required tread rubber of tread contour, fit through hanging then, heating and molded vulcanization, need equipment steel ring, the sulfuration inner tube of a tyre, envelope etc., this method retreads are because former carcass need make the tyre life loss of renovation quite big through secondary or three high temperature heating " heat ageing ", and the defective of delamination appears in Fan Xin tire easily simultaneously; (2) can only be fit to steel wire belt speed layer and not have damaged old tire renovation.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art part, a kind of retreading capsule shaping and segmented mold vulcanized tyre by winding method method is provided, this method not only is fit to the renovation of various tires, tire to the breakage of steel wire belt speed layer also can renovate simultaneously, has clear superiorities such as technology tire quality simple, renovation is good, equipment investment is few.
The present invention's technical scheme of taking of dealing with problems is:
The retreading capsule shaping and segmented mold vulcanized tyre by winding method method may further comprise the steps:
A) carcass is polished or taken off steel wire belt speed layer: the old tire that needs are renovated cuts, polishes, and perhaps the damaged steel wire belt speed layer of the old tire that needs are renovated is taken off, polishes smooth then;
B) kiss-coating or steel wire belt speed layer twine: with the tire brushing rubber cement that step a) is polished, perhaps the carcass of step a) is taken on the steel wire belt speed layer wrapping machine standard winding steel wire belt speed layer according to new tire;
C) tyre surface twines: with the tyre surface automatic wrapping machine at the carcass of kiss-coating or finished on the carcass of steel wire belt speed layer winding and twine tread rubber;
D) paste sidewall rubber: the sidewall rubber of fitting behind the winding tread rubber;
E) capsule shaping: the carcass that step d) is posted sidewall rubber is put into the capsule shaping central authority of radial vulcanizer, the capsule shaping central authority is dropped in the segmented mold, the locking segmented mold, capsule is inflated, under the effect of air pressure, capsule expands in tire, and outer surface of tire contacts with segmented mold and finishes typing;
F) segmented mold vulcanized: as to close after step e) is finished on the radial vulcanizer and cover, charge into conduction oil and vulcanize;
G) go out tire: after sulfuration is finished, open the radial vulcanizer, the capsule venting, central authority rises, and takes out tire, and tire carries out deburred after taking out;
H) finished product: check, packing, warehouse-in.
The described retreading capsule shaping and segmented mold vulcanized tyre by winding method method that gets, step b) steel wire belt speed layer twines the equipment that used steel wire belt speed layer machine is patent right people research and development.
The described retreading capsule shaping and segmented mold vulcanized tyre by winding method method that gets, c) the tyre surface winding is to adopt the tyre surface automatic wrapping machine once to finish the winding of tread rubber.
Described retreading capsule shaping and segmented mold vulcanized tyre by winding method method, the patent (application number: 200920025220.4) equipment that the segmented mold vulcanized used radial vulcanizer of step e) capsule shaping and step f) is the patent right people of getting.
In the capsule shaping technical process, the coupling mechanism force of typing pressure and segmented mold is to set according to tire specification and known typing pressure, clamp force.
Described segmented mold vulcanized, curing medium is common conduction oil, and curing temperature is to set according to known tire technical recipe and tire specification model; Segmented mold has the tyre tread active block, and can change according to the tyre tread demand; Utilize tread rubber elastomeric polymeric material high temperature foam theory, in sulfidation, be filled into automatically in the segmented mold decorative pattern, thereby obtain the required decorative pattern of tire.
The good effect of retreading capsule shaping and segmented mold vulcanized tyre by winding method method of the present invention is:
1, can be fit to the old tire renovation of steel wire belt speed layer breakage, having expanded can be for the scope of the tire that renovates;
2, tread rubber is directly once Wrapping formed, and need not presulfurization, omitted the technology that existing tyre surface is fitted, mould pressing technology tyre retreading tread rubber need require the presulfurization moulding according to tyre tread, avoid the tread rubber repeatedly to vulcanize the problem of " heat ageing ", overcome the shortcoming of tyre surface applying, the easy delamination of mould pressing technology;
3, adopt capsule shaping, need not steel ring, the inner tube of a tyre and envelope in the sulfidation, omitted the complicated procedures of forming of steel ring, the inner tube of a tyre and envelope dismounting, it is simple to have technology, and it is good to neutrality to finalize the design, the clear superiority that the tire quality of sulfuration is stable;
4, employing is segmented mold vulcanized, and segmented mold is replaceable, and tire is installed in and can directly vulcanizes the required decorative pattern of tire in the segmented mold;
5, small investment, economical and practical, do not need to invest pressing, envelope assembling/disassembling machine, vulcanizing tank; Capsule is changed number of times than the envelope durable wear and is lacked.
