Abstract
The present invention relates to the tyre building machine capsule drum tool improved; including moulding capsules drum; it is provided with, in moulding capsules drum, the secter pat that can move radially; secter pat is provided with forming tank; it is characterized in that: the position of the upper corresponding secter pat of described moulding capsules drum is arranged with tyre bead soft protection sheath; the periphery wall of described tyre bead soft protection sheath is provided with buffering forming tank, and the shape of cross section of this buffering forming tank is identical with the shape of cross section of described forming tank.Present configuration is simple, on the premise of not changing existing equipment structure, is additionally arranged tyre bead soft protection sheath on capsule drum, tire bead position provides protection reliably, improves tire product quality and qualification rate.
Description
Technical field
The present invention relates to a kind of tyre building machine capsule drum tool, the tyre building machine capsule drum tool being applicable to full-steel radial ply tubeless tyre tyre bead of a kind of improvement.
Background technology
Along with the cry of Don't Exceed Weight Limit is more and more higher, the tubeless type all-steel radial tyre with more high bearing capacity has occurred in face of us, and domestic tire enterprise is also thrown in more energy in the R&D and production of tubeless type all-steel radial tyre.
For tubed tyre, tubeless tyre is increasingly complex due to tyre bead portion structure, it requires that the technique of tire building is more perfect, if or use the moulding process identical with tubed tyre, certainly will cause some defects of tubeless tyre, the most directly defect is exactly easily to occur that in tire bead position bead material is distributed the series of problems such as not in place, starved, material stacking.This is also domestic and international tire enterprise common problem, analyze after deliberation, find reason be present tire enterprise commonly used moulding capsules drum tool hardness higher, in forming process, moving radially outward of secter pat can cause the tyre bead portion of green tyres to be deformed by severe crush, and after tyre vulcanization, the distribution of corresponding part material goes wrong, light then affect Life of Tyre, heavy then cause the bead chafing of tire, even tyre bead portion that the problems such as explosion occur.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art; the tyre building machine capsule drum tool of a kind of improvement is provided; its simple in construction; on the premise of not changing existing equipment structure; capsule drum is additionally arranged tyre bead soft protection sheath; tire bead position is provided protection reliably, improves tire product quality and qualification rate.
The technical scheme provided according to the present invention: the tyre building machine capsule drum tool of improvement; including moulding capsules drum; it is provided with, in moulding capsules drum, the secter pat that can move radially; secter pat is provided with forming tank; it is characterized in that: the position of the upper corresponding secter pat of described moulding capsules drum is arranged with tyre bead soft protection sheath; the periphery wall of described tyre bead soft protection sheath is provided with buffering forming tank, and the shape of cross section of this buffering forming tank is identical with the shape of cross section of described forming tank.
As a further improvement on the present invention, described tyre bead soft protection sheath uses the elastomeric material with good rebound performance to make.
The present invention compared with prior art, has the advantage that
(1) present configuration is simple; on the premise of not changing existing equipment structure; by being additionally arranged tyre bead soft protection sheath on capsule drum; tyre bead soft protection sheath provides protection reliably to tire bead position; protection green tyres tyre bead portion integrity before sulfuration; distortion preventing, reduces the probability that vulcanised tyre tyre bead portion goes wrong, improves tire product quality and qualification rate.
(2) owing to being additionally arranged tyre bead soft protection sheath, under the radial displacement of identical secter pat, secter pat can preferably pin tyre bead portion, prevents problems such as taking out on carcass.
Accompanying drawing explanation
Fig. 1 is structure and the applicable cases schematic diagram of the embodiment of the present invention.
Description of reference numerals: 1 moulding capsules drum, 2 secter pats, 3 forming tank, 4 tyre bead soft protection sheaths, 5 buffering forming tank, 6 tyre bead portions.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the tyre building machine capsule drum tool in embodiment is mainly made up of moulding capsules drum 1, secter pat 2 and tyre bead soft protection sheath 4.
As it is shown in figure 1, secter pat 2 is arranged in moulding capsules drum 1, secter pat 2 can move radially, and secter pat 2 is provided with forming tank 3, and when secter pat 2 moves radially, the tyre bead portion 6 to green tyres carries out extruded；Described tyre bead soft protection sheath 4 is set on moulding capsules drum 1 position of corresponding secter pat 2, and the periphery wall of described tyre bead soft protection sheath 4 is provided with buffering forming tank 5, and the shape of cross section of this buffering forming tank 5 is identical with the shape of cross section of described forming tank 3.
Tyre bead soft protection sheath 4 in the present invention uses the elastomeric material with good rebound performance to make.
Present configuration is simple, it is easy to accomplish, it is not only suitable for for tubeless type tire, it is possible to be applicable to there is le cas d'un pneumatique de type tube-type.Two forming machines are used to contrast; one capsule drum tool using the present invention; another uses the conventional capsule drum tool without tyre bead soft protection sheath 4, and comparative test result finds, the tire using the capsule drum tool of tyre bead soft protection sheath 4 to make occurs that the quantity of tyre bead problem greatly reduces.
Claims (1)
1. the tyre building machine capsule drum tool improved; including moulding capsules drum (1); it is provided with, in moulding capsules drum (1), the secter pat (2) that can move radially; secter pat (2) is provided with forming tank (3); it is characterized in that: the position of the upper corresponding secter pat (2) of described moulding capsules drum (1) is arranged with tyre bead soft protection sheath (4); the periphery wall of described tyre bead soft protection sheath (4) is provided with buffering forming tank (5), and the shape of cross section of this buffering forming tank (5) is identical with the shape of cross section of described forming tank (3)；
Described tyre bead soft protection sheath (4) uses the elastomeric material with good rebound performance to make.
