In the invention, a capsule type tyre setting drum is changed into the non-capsule two-stage tyre setting drum, thus realizing tyre positioning and setting under a full mechanical proper circle state, saving capsule manufacturing expense and use cost, improving precision and quality of tyre contour machining, and especially being suitable for moulding of high performance saloon car tyres.
Description
Technical field
The present invention relates to a kind of tire building machinery, specifically is a kind of non-capsule two-stage tyre setting drum that is used to make radial tyre of passenger car.
Background technology
The structure of the tyre setting drum of prior art (being capsule two-stage tyre setting drum) as shown in Figure 1, form by left side drum and right-hand drum two parts, left side drum and right-hand drum are installed by axle sleeve respectively and are connected on the telescopic shaft of make-up machine, on left side drum and right-hand drum, be equipped with cylinder power set and shrink-ring, shrink-ring generally is symmetrical set, shrink-ring is equated by plural piece piece number and alternate successively big secter pat (04) and little secter pat (07) constitutes, big secter pat is fixedlyed connected with corresponding slide block respectively with little secter pat, slide block is articulated and connected by the movable part of connecting rod and cylinder power set again, in the periphery of shrink-ring, be provided with bead clamp toe mouth; When tyre building machine utilizes setting drum that tire tire spare is carried out machine-shaping, the steel ring of tire tire spare by clamp on the toe mouth of shrink-ring periphery, inside to tire tire spare applies air pressure then, when the air pressure inside of tire tire spare reaches design load, again the processing typing is implemented in the outside of tire tire spare.Apply air pressure to the inside of tire tire spare, the shrink-ring sealing is necessary.The tyre setting drum of prior art, the method that shrink-ring is sealed is to adopt the capsule sealing, seal capsule (03) respectively by cylinder body briquetting (02) and positioning disk briquetting (06) with its sealing and fixing between the cylinder body (01) and positioning disk (05) of cylinder power set, reach the purpose that shrink-ring seals.Above-described capsule-type tyre setting drum, there is following shortcoming: during the work of (1) make-up machine, under the effect of the movable part of cylinder power set, shrink-ring becomes umbellate form to open or shrinks, shrink-ring opens at every turn and shrinks, and seal capsule is also done synchronous opening and shrink, therefore, seal capsule is damaged easily, thereby increases manufacturing expense and use cost; (2) because seal capsule is an elastic component, when tire tire spare is carried out machine-shaping, the steel ring of tire tire spare by after the seal capsule again by clamp on the toe mouth of shrink-ring, thereby influence the precision and the quality of the processing of tire building.
Summary of the invention
The objective of the invention is to overcome the shortcoming of the above capsule two-stage tyre setting drum, a kind of non-capsule two-stage tyre setting drum is provided.
The present invention, form by left side drum and right-hand drum, left side drum and right-hand drum are installed by left axle sleeve and right axle sleeve respectively and are connected on the telescopic shaft of make-up machine, left side drum and right-hand drum are equipped with cylinder power set and shrink-ring, the cylinder power set comprise cylinder body, cylinder cap and loose collar, and cylinder body is fixedlyed connected with axle sleeve; Left shrink-ring on the drum of left side and the right shrink-ring on the right-hand drum are symmetrical set, and in the periphery of shrink-ring, are provided with bead clamp toe mouth, and the bead clamp toe mouth on the described shrink-ring periphery is a ring-shaped groove; Shrink-ring is equated by plural piece piece number and alternate successively big secter pat and little secter pat constitutes, big secter pat is fixedlyed connected with small slide block with big slide block respectively with little secter pat, big slide block and small slide block are articulated and connected with big connecting rod and small rod respectively, the loose collar of big connecting rod and small rod and cylinder power set is articulated and connected, big slide block and small slide block are slidingly connected by guide groove and positioning disk, positioning disk is fixedlyed connected with axle sleeve, on the contact-making surface between big secter pat and the little secter pat, is provided with diaphragm seal.
The present invention, described diaphragm seal is pasted and fixed in the groove of little secter pat reservation, and the thickness of diaphragm seal is slightly larger than the degree of depth of groove.
The present invention on loose collar, can be provided with the shrink-ring sealing ring; On cylinder body, the loose collar limited block can be set; On positioning disk, the slide block limited block can be set.
The present invention has following good effect: 1, owing to adopt no capsule structure typing, substituted original capsule-type typing, save two capsules on the former assembly drum, the manufacturing expense and the use cost of having saved capsule; 2, owing to adopt no capsule structure typing, when tire tire spare is carried out machine-shaping, the steel ring of tire tire spare directly by clamp on the toe mouth of shrink-ring, after opening, shrink-ring is the proper circle state, realize tyre bead location and moulding under the fully mechanical proper circle state, thereby improve the precision and the quality of tire building processing; 3, because the bead clamp toe mouth on the shrink-ring periphery is designed to ring-shaped groove, when shrink-ring becomes umbellate form to open, groove has limited the free degree of fetus wire loop, guarantee when operations for forming, wire loop is unshift, green tyres is more stable when roll-in is finalized the design, and makes its produced fetus precision higher, is particularly suitable for the moulding of exotic performance car tire.
