Description

A kind of giant-scale steel line meridian engineering machinery tyre vulcanizer

Technical field

The present invention relates to tyre vulcanization, particularly a kind of machinery for giant-scale steel line meridian engineering machinery tyre sulfuration.

Background technology

Countries in the world increase rapidly owing to the mineral reserve such as coal, iron ore, copper being produced to the demand of resource, pulled the demand of extractive industry to mining machinery and large-scale haulage vehicle, especially quarry tipper increases sharply by the heavy construction tire market demand, thereby causes the global shortage of giant-scale engineering tyre of the especially large specification of engineering tire.Even in fourth quarter in 2008 of financial crisis most severe impact, global engineering giant embryo is sold still good.

Engineering giant embryo mainly applies to digging and port traffic industry, and market is specific.Extractive industry is mainly used the mine truck of 108 tons to 260 tons of load-carryings, and the situation that supply falls short of demand has appearred in the giant all-steel wire radial engineering machinery tyre of supporting 30.0R51,36.00R51,37.00R57,40.00R57 equal-specification with it.This class giant tyre is because price is high, the life-span is short, consumption is large, production difficulty is large, for a long time, offshore company takes strict technical know-how measure to China, only have at present French Michelin, solid special, the Japanese general woods stone of the U.S. and gondola Pirelli four giant tyre giants to produce, China or blank, can only rely on import.

At present domestic also have some tire production producers can produce the all-steel radial tyre of the following specification of 27.00R49, and the giant tyre of larger specification, due to equipment reason, also can only the low oblique configuration tire of production performance, want the full steel wire meridian giant tyre that production performance is superior, first the technology barriers that Gonna breakthrough giant-scale engineering tyre is equipped, develop the giant-scale engineering tyre of suitable for China and produce equipment, for final production goes out giant all-steel radial engineering machinery tyre, provide powerful technique guarantee.

The applicant is for solving the renovation problem of giant engineering machinery tyre, the patent of " frame-type giant engineering machinery tyre retreading vulcanizing machine " by name was once proposed, the number of applying for a patent ZL200620035603.6, it has adopted frame structure, fore-set-drift locked mode mode, the technical characterictics such as the hydraulic drive of folding mould and active model, the needs that met giant engineering machinery tyre renovation, the basic mechanical design feature of this machine and structure also can meet the production requirement of giant engineering machinery tyre new tyre substantially.

The problem existing is: 1. fore-set is that inclined-plane coordinates with drift, can not guarantee that fore-set is vertical when locked mode, and fore-set may tilt, thereby causes stressed badly, and stability is slightly poor.2. the upper and lower central cylinder of vulcanizer, without cooling device, is consequently often changed seal, causes shutdown maintenance, and impact is produced.3. former vulcanizer is the admission pipeline of a direction, thus mould the temperature difference is larger everywhere, the inherent quality of the tire produced of impact.4. go up side form in the process of matched moulds, owing to opening the asynchronous of closing cylinder, easily cause doubling.5. internal mold side form, without positioner, easily causes pattern dislocation, affects Appcarance guality of tyres.6. the picking-up of descending side form is by a central cylinder effect, can cause in counterdie uphill process steadily not inadequate with holder mould strength.7. shifting out by hoist engine of drag, lower flat board completes, and because being flexibly connects, have impingement phenomenon, and floor space is large.
