Description
Technical field
Tyre production equipment technical field is the utility model is related to, particularly belongs to a kind of rotary folding first stage building drum dress
Put.
Background technology
Radial expansion drum in the country's uses double-slide block type linkage mostly at present, and double-slide block type radial expansion drum is to pass through a left side
The axial movement of sliding seat on main shaft, is converted into the radial motion of drum by the position-limiting action of right positioning disk, therefore drum is stretched
Contracting scope is limited be subject to sliding seat axial stroke.In order to reach predetermined radial expansion ratio（Be unfolded radius and constriction radius it
Than）, sliding seat must possess certain stroke.And the drum that the size of sliding seat stroke directly affects the drum that stretches is roomy small.Stroke
Bigger, drum is wide bigger, and telescopic extensions are bigger, and radial expansion ratio is bigger, on the contrary then smaller.In view of above feature, which stretches
Contracting drum only just meets design requirement in the case of roomy small no strictly limitation to drum, this is also the limitation of the structure.
It can not just meet design requirement when running into wide smaller, radial expansion the is bigger situation structure of drum, such as Patent No.
The assembly drum that ZL2012202736069 is announced.
Utility model content
The purpose of the utility model is to overcome the defects of the above-mentioned prior art, a kind of rotary folding first stage building drum fills
Put, using rotary motion, drum, drum shoulder is only done radial motion, realize zero stroke in the axial direction, greatly shorten the axis of assembly drum
Internally space, makes structure compacter.
To achieve these goals, a kind of rotary folding first stage building drum device provided by the utility model, includes master
Axis, drum shoulder, the drum being fixedly connected with drum shoulder, the radial expansion device and rotary folding device of drum shoulder, the radial expansion dress
Put and be made of guide rod and guide sleeve, the guide rod is fixed on main shaft perpendicular to main shaft and by guide holder, the drum
On have guide sleeve corresponding with guide rod, the rotary folding device is made of main shaft, rotary sleeve, rotating seat, connecting rod, the rotation
Pivoted housing is screwed on rotating seat, and the rotary sleeve can be rotated back and forth along main shaft surface and moved, the connecting rod one
End is connected by axis pin with drum, and the other end is connected by axis pin with rotating seat.Rotating seat is driven along main shaft by rotary sleeve
Surface rotates back and forth movement, and drum shoulder only does radial expansion movement with drum under the action of guide rod, abandoned traditional handicraft
Middle double-slider pattern, although radial expansion movement can be completed, will be also axially moved.
Preferably, the bulging shoulder is made of big drum shoulder and side drum shoulder, and the connecting rod is made of big connecting rod and small rod, described
The length of big connecting rod is longer than small rod, and the big drum shoulder connects big connecting rod, and the side drum shoulder connects small rod.Big drum shoulder with it is small
When the expansion of drum shoulder and contraction, since the length of large and small connecting rod is different, the start angle that they are moved is different, this ensures that
Large and small bulging shoulder is non-interference in motion process is overlapped, and can be mutually closed again in expansion process, forms seamless proper circle state.
Preferably, the guide holder is additionally provided with position-arresting disk.It can be used for the stroke for limiting drum radial development, reduce row
Journey error, makes the working diameter of assembly drum more accurate, improves the formed precision of green tyres.
Preferably, the guide holder is divided into left guide holder and right guide holder, and the shaft shoulder, small flat key are additionally provided with the main shaft
And retaining ring, the right guide holder realize positioning by the shaft shoulder and small flat key, the left guide holder passes through retaining ring and small flat key
Realize positioning.
Preferably, the drum divides big drum frame and side drum stand, and the big drum frame corresponds to big drum shoulder, and side drum stand corresponds to side drum
Shoulder, is welded with adjustment block on the side drum stand, by adjusting block, can coordinate by adjusting screw to adjust adjustment block with drum
Tightness, it is overall closer to proper circle state to make to rouse shoulder, is conducive to improve the molding qualification rate of green tyres.
Preferably, the wide ring of tune is additionally provided with the drum.
The utility model has the advantage of：Drum, drum shoulder only do radial motion, realize zero stroke in the axial direction, contract significantly
The axial inner space of short assembly drum, makes structure compacter, effectively reduces drum width, but drum big especially suitable for magnification is wide small
Occasion.
