4, can economize on the use of funds 8～160,000 yuan for every.

Below the utility model is further described:

As shown in the figure, this assembly drum is made up of power transmission shaft, coupling pin, 2 conical disc, 10 sliding tile framves, 5 big multiple watt, 5 little multiple watt, 5 big multiple watt width adjusting plates, 5 little multiple watt width adjusting plates, 2 gears, 2 tooth bars, beam barrel, axle sleeves.Coupling pin fuses power transmission shaft and one of them conical disc, guiding bearing pin on the conical disc connects together 10 sliding tile framves and 2 conical disc again, fix large and small multiple watt and large and small width adjusting plate on the garden perimeter surface of sliding tile frame, have between wherein per two big multiple watt one little multiple watt.Conical disc is enclosed within on the axle sleeve, and moves on axle sleeve, and axle sleeve is enclosed within on the beam barrel, and 2 gears are installed in the beam barrel, the wheel and rack engagement, and tooth bar and one of them conical disc are fixed together.

Operation principle: drive the air cylinder driven power transmission shaft and move right, power transmission shaft drives conical disc to the right by coupling pin, another conical disc is moved to the left under the rack-and-pinion transmission simultaneously, two conical disc are under the effect of rack-and-pinion, locking phase is to moving, when conical disc moves, by the guiding bearing pin on the conical disc force the sliding tile frame along the guide finger diameter of axle to strutting.Because large and small multiple watt and large and small multiple watt width adjusting plate connect together by dovetail key and sliding tile frame, also radially strut with width adjusting plate so the sliding tile frame drives multiple watt, and form the level and smooth Cylinder of a technology diameter, use during for moulding tire tire blank molding thereupon.After a green tyre moulding is finished, drive the commutation of cylinder air inlet and exhaust valve, the piston rod retraction makes two opposing moving of conical disc by power transmission shaft, drives sliding tile frame, multiple watt, width adjusting plate radial contraction.Because the guide finger axial rake on the little multiple watt sliding tile frame is greater than the inclination angle of big multiple watt of sliding tile frame guiding bearing pin, so little multiple watt and width adjusting plate are under the drive of its sliding tile frame, prior to big multiple watt sliding tile frame radial contraction, the final 5 big multiple watt regular pentagons of forming external gardens less than the technology diameter unload the green tyre of forming smoothly from assembly drum.

Above-mentioned operation principle is the technical process of production technology diameter when being 13 inches tires.When the production technology diameter is 14,15,16 inches tire, pull down multiple watt and width adjusting plate on the assembly drum, change diameter and be 14,15,16 inches multiple watt and width adjusting plate and get final product.The multiple watt of diameter with width adjusting plate increases, and actual is that the multiple watt of thickness with width adjusting plate has increased, so multiple watt angle [alpha] ₃And β ₁And width adjusting plate angle [alpha] ₂β ₂Also change.The angle [alpha] of pairing big multiple watt and big multiple watt width adjusting plate when multiple watt and width adjusting plate diameter dimension are 13,14,15,16 inches ₃, α ₂Be 60 °, 63 °, 63.5 °, 64 °, corresponding little multiple watt and the angle beta of little multiple watt width adjusting plate ₁, β ₂It is 12 °, 9 °, 8.5 °, 8 °.
