Description
Technical field
The present invention relates to tyre production equipment technical field, particularly belong to a kind of band position-arresting disk Telescopic rotating fold one section into
Type rouses.
Background technology
Domestic radial expansion drum 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 position-limiting action of right positioning disk, the axial movement of sliding seat on main shaft is converted into the radial motion of drum, therefore drum is stretched
Contracting scope is limited by sliding seat axial stroke.In order to reach predetermined radial expansion ratio（Deploy 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, the structure is stretched
Contracting drum only just meets design requirement in the case of roomy small no strictly limitation to drum, and this is also the limitation of the structure.
Design requirement can not just be met 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.
The content of the invention
The defects of it is an object of the invention to overcome above-mentioned prior art, a kind of band position-arresting disk Telescopic rotating fold one section into
Type rouses, and using rotary motion, drum, drum shoulder is only done radial motion, realizes zero stroke in the axial direction, greatly shorten assembly drum
Axial inner space, make structure compacter, the wide small occasion of but drum big especially suitable for magnification.
To achieve these goals, a kind of band position-arresting disk provided by the invention is flexible and rotary folding first stage building rouses, bag

When the expansion of drum shoulder and contraction, because the length of large and small connecting rod is different, start angle when they are moved is different, can thus protect
It is non-interference in motion process to demonstrate,prove big side drum shoulder, so that drum shoulder forms seamless full circle state at work, in inoperative
When each other form gap.
Preferably, the guide rod by left guide rod and right guide post group into.
Preferably, the main shaft surface is fixed with guide holder, and the guide rod is fixed on main shaft by guide holder, described
Guide holder is additionally provided with position-arresting disk.It can be used for the stroke for limiting drum radial development, reduce journey error, make the work of assembly drum
Make that diameter is more accurate, improve 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, adjustment block is welded with the side drum stand, by adjustment block, can be coordinated by adjusting screw to adjust adjustment block with drum
Tightness, make to rouse that shoulder is overall closer to proper circle state, be advantageous to improve the qualification rate of green tyres shaping.
Preferably, it is additionally provided with the drum and adjusts wide ring.
Preferably, also include mandrel, axially turn rotation device.
Preferably, the axial direction turns rotation device and includes main shaft, mandrel, rotary sleeve, trundle, the rotary sleeve
For hollow cylindrical, and it is enclosed on the outside of main shaft, the rotary sleeve side is additionally provided with spiral guide slot or through hole, and the main shaft is
Hollow cylindrical, and its side is provided with the straight-line guidance through hole of axial direction, and the mandrel is arranged on inside main shaft and it
Surface is fixedly connected with trundle, and the trundle is through straight-line guidance through hole and enters spiral guide slot or through hole, respectively with
Straight-line guidance through hole, spiral guide slot or through hole connection, the rotating seat are arranged on the outside of rotary sleeve and are fixedly connected.Mandrel exists
It can be done by external force in main shaft and axially moved back and forth, trundle is in mandrel and straight-line guidance through hole, spiral guide slot or through hole
Collective effect under, promote rotary sleeve rotation, axial movement is converted into rotary motion.
Preferably, the trundle also includes the first sliding sleeve and the second sliding sleeve, and first sliding sleeve is arranged on straight line and led
To through hole, roll and connect with straight-line guidance through hole, second sliding sleeve is arranged at spiral guide slot or through hole slip, with spiral shell
