Abstract
The utility model provides a practical and novel bracer for a capsule inverse covering assembly drum, which consists of a steel wire ring, bracers and a rubber ring, wherein, the bracers are symmetrical on the left and right; the bottom edge of the inner contour of each bracer is in a sloping side polygonal structure, and the matched rubber ring is also in a sloping side polygonal structure corresponding to the bottom edge of the inner contour of each bracer. The practical and novel bracer for the capsule inverse covering assembly drum ensures the sticking and pressing precision of the steel wire ring formed by a tyre blank of a regular hexagonal meridian tyre, and has stabilized forming quality.
Description
Technical field
The utility model relates to a kind of mechanical bracer that whole steel wire radial tyre is used of making, and is specifically related to the bracer of the capsule reverse wrap molding drum of applying, compacting and the location of glue component in the fine realization green tyres of a kind of energy forming process.
Background technology
Capsule reverse wrap molding drum is the critical component that all-steel radial is produced, and with the double-capsule pack arrangement that is all-trans, assembly drum adopts two cylinders to promote connecting rods and supports fast structure domestic all-steel radial tyre fetus assembly drum, makes tyre bead locking, avoids slippage mostly; Drum adopts three layers of thin nested structure in the assembly drum, thin cover condensation during typing; Wherein the bracer structure is divided into two kinds of versions according to the positive hexangle type and the oblique hexangle type of wire loop, and following structures is at using positive hexagonal wired ring whole steel wire radial tyre assembly drum bracer to carry out improved invention.Specify as follows:
Originaling forming support block structure is an inverted T shape groove structure according to positive hexagonal wired ring structural design, the glue ring on the built-in band of T type groove inclined-plane, and locking into by the support power of bracer when moulding, wire loop carries out the applying and the compacting of other glue components of tire.But find that in actual production process there is following defective in this kind bracer structure: 1. when tyre element is fitted, cause out-of-flatness, can cause the glue component skew of bracer position during pressing because of the distance of reverse-wrapped capsule and built-in glue ring is excessive; Cause when 2. bracer rises the positive hexagonal wired ring of locking and take out in the reverse-wrapped capsule and influence tire body cord and glue component displacement, the positioning accuracy in the time of can not guaranteeing tire building; 3. when fitting other tyre elements, takes out by fetus overdetermination type the crooked or distortion generation waster of sulfuration back carcass cord because of interior pressure existence causes on the carcass cord.
The utility model content
The bracer that the utility model provides the capsule reverse wrap molding of applying, compacting and the location of other glue components of the fine realization tire of a kind of energy to rouse.
In order to solve above technical problem, a kind of capsule reverse wrap molding drum utility model bracer of the present utility model, form by wire loop, bracer, glue ring, it improves structure: described bracer left-right symmetry, and the profile base is the hypotenuse polygonized structure in the bracer, its adapted glue ring also be with bracer in the corresponding polygonized structure in profile base.
The hypotenuse angle of profile base and glue ring is in the described bracer: 5～25 °.
The advantage of above structure is: by original positive hexangle type all-steel radial assembly drum bracer the tire quality case study takes place in actual use, propose novel bracer structure and carry out the actual production use.Bracer after the improvement has following advantage: the distance that 1. reduces between bracer glue ring and the reverse-wrapped capsule is in the 4mm, avoids reverse-wrapped capsule to subside causing glue component to fit and the distortion during pressing, the displacement when reducing parts and fitting, raising applying precision; 2. the profile base changes 15 ° of hypotenuse polygonized structures in the bracer, the processing of left and right sides bracer symmetry, and its adapted glue ring also changes 15 ° of polygonized structures into, can the production part displacement when new bracer rises the locking steel wire circle, positioning accuracy when improving moulding; New bracer structure can be furnished with clamping action to wire loop both sides carcass when fetus inflation overdetermination type, actual measurement reduces on the carcass cord takes out more than the 8mm, improves the attaching and compacting precision of triangular rubber core and carcass cord and belt layer tread composite members and carcass cord simultaneously.
Above-mentioned capsule reverse wrap molding drum uses novel bracer structure, can guarantee that wire loop is the applying and the bonding accurcy of regular hexagon all-steel radial fetus moulding, stablizes Forming Quality.
Description of drawings
Figure is the utility model structural representation.
The specific embodiment
As shown in the figure, reverse-wrapped capsule 1 is coated on the reverse wrap molding drum 2, and drum adopts three layers of movable thin cover 7 structure in the assembly drum, thin cover 7 condensations during typing.There is the mechanical bracer 5 of the wire loop 3 of fixing positive hexangle type the inboard of the thin cover 7 of described assembly drum, it is 15 ° polygon that mechanical bracer 5 is designed to the base hypotenuse, the glue ring of corresponding shape is set in the polygon groove of this wire loop, like this, can the production part displacement when new bracer rises the locking steel wire circle, positioning accuracy when improving moulding; New bracer structure can be furnished with clamping action to wire loop both sides carcass when fetus inflation overdetermination type, actual measurement reduces on the carcass cord takes out more than the 8mm, improves the attaching and compacting precision of triangular rubber core and carcass cord and belt layer tread composite members and carcass cord simultaneously.
The inboard of assembly drum is provided with the bracer 5 that some sizes are equal to, and the profile base all changes 15 ° of hypotenuse polygonized structures within it, the distance that reduces simultaneously between bracer glue ring and the reverse-wrapped capsule is in the 4mm, avoid reverse-wrapped capsule to subside causing glue component to fit and the distortion during pressing the displacement when reducing the parts applying.Improve the applying precision.
All connect connecting rod 4 on above-mentioned each bracer 5, the other end of connecting rod 4 is fixed on the axle sleeve 8; And be connected with cylinder 6.Ventilation by cylinder 6 realizes tyre bead locking, avoids slippage.
