Specific embodiment
The course of work of the present invention is: this bladder-forming drum for small industrial tyre is installed on the final drive shaft of make-up machine mainframe box.In the process of tire building, behind the location of finishing applying of carcass cord and wire loop, drive positive and negative screw-thread drive shaft 2, power transmission shaft nut 9 drives drive blocks 8 and moves to desired location along the promotion of the groove on the hollow spindle 1 left and right sides drum to the centre; The back cavity air feed of giving each cylinder in the polyphone air cylinder group simultaneously is to produce thrust, acting in conjunction is on cylinder I piston 3-2, produce and make a concerted effort, making the secter pat connection rod set promote fastening carcass secter pat group rises along the secter pat positioning disk, finish operation fastening and the sealing carcass, finish the carcass pre-setting to carcass inner chamber and the ventilation of tire shoulder capsule simultaneously; Suit crown layer drives positive and negative screw-thread drive shaft 2, makes power transmission shaft nut 9 drive drive block 8 and moves to desired location along the promotion of the groove on main shaft left and right sides drum to the centre; Continuing to finish carcass to the ventilation of carcass inner chamber and tire shoulder capsule simultaneously finally finalizes the design; Give two reverse-wrapped capsule ventilations, finish anti-package, the roll forming on sidewall; The back cavity exhaust of each cylinder in the air cylinder group, ante-chamber is given gas simultaneously, and secter pat connection rod set band secter pat and is resetted; Drive positive and negative screw-thread drive shaft 2, make power transmission shaft nut 9 drive drive block 8 and move to original position to both sides along the promotion of the keyway on main shaft left and right sides drum.
See also Fig. 1, Fig. 2, the same with general assembly drum, this bladder-forming drum for small industrial tyre is installed on the make-up machine mainframe box.This bladder-forming drum for small industrial tyre, comprise air-channel system, the hollow spindle 1 that links to each other with mainframe box, right-and-left threaded power transmission shaft 2 is arranged, power transmission shaft 2 is positioned at hollow spindle 1, about the side drum of two symmetrical configuration be installed in outside the hollow spindle 1, the capsule retention mechanism is drawn together in each side bulge, the fastening tyre bead of secter pat mechanism, between the left and right sides drum, the structural member that is used for the supporting carcass tube is installed, the fastening tyre bead of described secter pat mechanism comprises the secter pat group, and guiding and bracing or strutting arrangement, drive the one group of connecting rod of secter pat and the cylinder of drivening rod, connection rod set is connected on the same cylinder simultaneously, and the structure of said structure and general assembly drum is basic identical.
The difference of this invention and general assembly drum is: the cylinder that drives secter pat, if adopt the structure of the single cylinder of general assembly drum, because the restriction in space, cylinder bore is too little, piston can not provide enough thrust, remove to promote secter pat locking tyre bead, finish inflation, anti-package and the roll extrusion of fetus.Therefore the cylinder of drive secter pat of the present invention has adopted one group of polyphone cylinder, and described polyphone cylinder comprises the cylinder I 3 that is sleeved on the hollow spindle 1, is sleeved on cylinder I I4, cylinder I II5 on the cylinder I inner core 3-1; Wherein cylinder I 3 comprises cylinder I inner core 3-1, cylinder I inner core 3-1 is sleeved on the hollow spindle 1, the structural similarity of the guiding of secter pat and bracing or strutting arrangement and general assembly drum, be installed on the cylinder I inner core 3-1, cylinder I inner core 3-1 can slide along hollow spindle 1, it is last and hinged with connecting rod 7 that cylinder I piston 3-2 is sleeved on cylinder I inner core 3-1, and can slide along cylinder I inner core 3-1, cylinder I drive end bearing bracket 3-3, rear end cap 3-5 and cylinder I urceolus 3-4, cylinder I drive end bearing bracket 3-3, rear end cap 3-5 is sleeved on the cylinder I inner core 3-1, the composition of cylinder I 3 is except that the form of piston, and is similar with general assembly drum; Cylinder I I 4 comprises the cylinder I I piston 4-2 that is packed on the cylinder I piston 3-2, by the double cylinder I I inner core of doing of cylinder I piston 3-2, cylinder I I urceolus 4-4, the drive end bearing bracket 3-5 of cylinder I I and cylinder II rear end cap 4-5, cylinder I I rear end cap 4-5 is sleeved on the cylinder I piston 3-2, and cylinder I I drive end bearing bracket is by double the doing of rear end cap 3-5 of cylinder I; Cylinder I I 4 can have several as required; Cylinder I II5 comprises the cylinder I II piston 5-2 that is packed in cylinder I piston 3-2 rearward end, by cylinder I piston 3-2 and the double cylinder I II inner core of doing of cylinder I inner core 3-1, cylinder I II urceolus 5-4, cylinder I II drive end bearing bracket 4-5 and cylinder III rear end cap 5-5, cylinder I II drive end bearing bracket is done by the rear end cap of cylinder I I is double, rear end cap 5-5 one end and the cylinder I inner core 3-1 of cylinder I II join, the other end and drive block 8 join, cylinder I II rear end cap 5-5 is sleeved on the hollow spindle 1, can slide along hollow spindle 1, drive block 8 is driven by power transmission shaft 2, can move along the keyway on the hollow spindle 1, drive block 8 drives cylinder I II rear end cap 5-5, and cylinder I II rear end cap 5-5 drives cylinder I inner core 3-1, moves to the centre thereby promote whole side drum; The structure of above-mentioned polyphone cylinder, because the piston of cylinder I I4, cylinder I II5 all is packed on the cylinder I piston 3-2, thrust on the cylinder I piston 3-2 not only comprises from cylinder I 3, also comprise from cylinder I I4, cylinder I II5, it is making a concerted effort that thrust on the cylinder I piston 3-2 is cylinder I 3, cylinder I I4, cylinder I II5 produced, therefore cylinder I I4 can have a plurality ofly as required, and this polyphone cylinder can produce enough making a concerted effort, and locks tyre beads by connecting rod 7 promotion secter pats 6; Cylinder I 3, cylinder I I4, the exhaust of cylinder I II5 back cavity, cylinder I I4, cylinder I II5 ante-chamber air feed, acting in conjunction is in cylinder I piston 3-2, and cylinder I piston 3-2 pulling connecting rod 7 drives secter pat 6 and resets.Thereby finish inflation, anti-package and the roll extrusion of fetus.Keep gas circuit that cylinder finishes exercises on cylinder wall, use the sealing ring leakproof between cylinder.
Consider overall structure of the present invention, described cylinder I I4 have one comparatively reasonable.
See also Fig. 1, Fig. 3, because the physical dimension of this bladder-forming drum for small industrial tyre is less, it is less with the bearing pin of cylinder I piston 3-2 to connect connecting rod 7, but piston I is bigger by the power that bearing pin acts on the connecting rod 7, bearing pin fractures easily, therefore connecting rod 7 with and its hinged cylinder I piston 3-2 between pad is installed, it is adaptive mutually to fill up the face that contacts with connecting rod 7, to realize that cylinder I piston 3-2 promotes connecting rod is the transmission of finishing power by described pad, rather than finishes the transmission of power by bearing pin; When secter pat 6 resets, load not, resistance is very little in other words, is the transmission of having finished power by bearing pin, thus secter pat 6 when resetting pad inoperative.
