Description
Technical field
The present invention relates to tyre production equipment technical field, a kind of axial stretching rotary folding first stage building is particularly belonged to
Drum.
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 by 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 is on the contrary then smaller than bigger.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.
When running into the wide smaller, radial expansion of drum, than larger situation, the structure can not just meet design requirement, such as Patent No.
The assembly drum that ZL2012202736069 is announced.
The content of the invention
