Abstract
A mechanical shaping drum including a carcass fastening mechanism features that the said mechanism has a cylinder-piston driven connecting rod unit which is composed of cylinder, piston, connecting rod of piston, sectorial block, guide spline and sealing plate. Its advantages are firmly fixing the type blank to the mechanical shaping drum, high antiwear performance and durability of the mechanical shaping drumo and low cost of production.
Description
(1) technical field:
The present invention relates to a kind of rubber tyre machinery, produce the mechanical assembly drum of the body formed supporting personal module of the special equipment once time forming machine inner tube of a tyre especially for the meridian high-capacity tyre.
(2) background technology:
Existing meridian high-capacity tyre once time forming machine, the special-purpose carcass building drum of adapted is inflatable capsule shaping drum, and it need fill the compression air in capsule in carcass final molding process, after capsule is expanded, also need lean on independent metal push-plate, oppress capsule deformation, finish the sidewall and the tire shoulder position compacting operation of tire final molding, after finishing this operation, also need gas in the capsule is given off, make capsule return to original state, just can carry out the operation of the next item down operations for forming.Operations such as this inflation, venting, push-plate compacting need the stand-by period longer, and the compacting that compressing is out of shape by push-plate of capsule inflation back belongs to indirect flexible compacting, so compaction quality can not guarantee uniformity, therefore can bring certain harmful effect to the inherent quality of green tyres moulding.
(3) summary of the invention:
The objective of the invention is to the assembly drum that designs a mechanism, it is that a kind of carcass final molding for meridian high-capacity tyre once time forming machine provides the new structure mechanical assembly drum with the supporting special use of make-up machine.
Technical scheme of the present invention: a kind of mechanical assembly drum, comprise turn-screw, bearing block, main shaft, the main shaft cylinder, the main shaft bearing rear end cap, the nip drum arm, elastic rubber ring, the main shaft piston, nut seat, breather adapter and fastening carcass mechanism, it is characterized in that in the said fastening carcass mechanism cylinder piston drive linkage being arranged, said cylinder piston drive linkage is by the secter pat cylinder block, secter pat cylinder block piston, piston rod, secter pat, the lead key dish, sealing gasket is formed, secter pat cylinder block piston is housed in the secter pat cylinder block, on the secter pat cylinder block piston piston rod is arranged, piston rod is connected with secter pat, secter pat is installed in the lead key dish according to the feather key on the lead key dish, the secter pat top is provided with groove, and sealing gasket is housed in the groove.
The cylinder piston drive linkage that has in the above-mentioned said fastening carcass mechanism has 72 groups of symmetry.
The rear end cap of above-mentioned said main shaft cylinder is to be made of bimetal structure, and the non-movable friction of its end cap position adopts common aluminum alloy to form the outer ring, and the movable friction of its end cap position adopts the high abrasion aluminium copper to form inner ring.
The course of work of the present invention: in fastening carcass mechanism cylinder piston drive linkage, the piston actuated connecting rod, connecting rod pulling secter pat, make secter pat rise and descend along the lead key dish, the sealing gasket that in the secter pat top groove, is equipped with, guaranteed the sealing of aeration settling in fetus, can also guarantee in nip drum arm compacting sidewall, tire shoulder process, the fetus obscission can not take place.Adopt mechanical assembly drum, promptly do not re-use capsule, saved inflation, evacuation time, the final compacting of its moulding fetus is by one group of main shaft air cylinder device, drive the uniform nip drum arm in both sides, in to carcass in the aeration settling, can be fast finish sidewall and the direct compacting operation of tire shoulder fetus by the nip drum arm.The pressure of nip drum arm end rolling nip drum by one group of elastic rubber ring control, can guarantee the reliability of the uniformity and the compacting operation of nip drum pressure.This has not only improved the final compaction quality of moulding fetus, but also compacting operation efficient has been improved 50%.
Superiority of the present invention is: 1, by the secter pat mechanism that has groove and sealing rubber pad that is evenly distributed on symmetrical two side positions on the mechanical assembly drum, under the driving of cylinder, piston, connecting rod, evenly rise synchronously, can make fetus firmly on mechanical assembly drum, the reliability of assurance aeration settling sealing in fetus, and prevent that fetus from the tire shoulder compacting process of sidewall obscission taking place final enforcement; 2, main shaft cylinder rear end cap neck bush adopts bimetal structure, has improved the wearability and the durability of mechanical assembly drum main shaft cylinder rear end cap with wear-resisting aluminium copper, has reduced manufacturing cost.
