Direct sulfuration device of radial parting mold of radial ply tyre
Technical field
The present invention relates to the radial vulcanization plant, specifically a kind of direct sulfuration device of radial parting mold of radial ply tyre.
Background technology
As everyone knows, the sulfuration of radial is contained in activating mold on the tyre vulcanizer and finishes, because tyre vulcanization is to carry out under higher temperature and pressure, therefore can produce bigger pressure in tire-mold, and mould is opened.In order to offset the pressure of mould inside, sulfidation is carried out smoothly, the closed after cure machine of mould must provide a coupling mechanism force to mould, so this tire-mold also must be worked simultaneously with vulcanizer.According to the presentation mode of coupling mechanism force, vulcanizer at present commonly used is divided into two kinds of mechanical vulcanizer and hydraulic pressure vulcanizing machines.These two kinds of ways all are to be vulcanizer from the both direction up and down of mould to the mould locking of exerting pressure by the device beyond the mould, and a kind of way is a mechanical force, and another kind of way is a hydraulic coupling.According to the difference of vulcanizer entablature motion mode, the mechanical type vulcanizer is divided into crank connecting link elevating translational type vulcanizer and the convertible vulcanizer of crank connecting link lifting again.
Above-mentioned vulcanization plant complex structure, bulky and heavy, in folding mould and locked mode process, except the weight and interior pressure that will overcome mould, also to overcome the weight of the moving component of vulcanizer own, and complicated operation.Because the volume of whole vulcanization plant is bigger, make entire equipment maximize in addition, improved the production cost of tire.When production engineering vehicle during with giant tire especially giant tyre, problems such as its manufacturing cost is huge, processing difficulties just become very outstanding.Will fundamentally address the above problem, at first will simplify vulcanization plant, the clamping mechanism of wherein how simplifying in the vulcanization plant is the key issue that needs solution.By changing the locked mode mode of tyre adjustable die, cancel the vulcanizer of existing structure, can fundamentally address the above problem.Having occurred use bolt or lock ring etc. at present locks it, but mostly existing locking mode is to adopt manual locking, because the pressure in the sulfidation in the entire equipment is bigger, the bolt that uses during locking or the number of lock ring are more relatively, so the locking time of manual locking is longer, and production efficiency is low.
Summary of the invention
In order to address the above problem, the present invention proposes a kind of direct sulfuration device of radial parting mold of radial ply tyre that can realize auto lock, its volume is little, and is in light weight, simple in structure, and the locking time is short, greatly reduces the production cost of tire.
The present invention adopts following technical scheme to realize: a kind of direct sulfuration device of radial parting mold of radial ply tyre, comprise upper cover plate, middle die sleeve, lower shoe, epipleural, arc seat, pattern block and lower side panel, pattern block is fixed on the inner surface of corresponding arc seat, axis direction at mould between arc seat and the lower shoe is located by connecting, there is not axial displacement each other, promptly do not move up and down with middle die sleeve and upper cover plate, wherein, outer rim at lower shoe evenly is provided with hydraulic locking apparatus along its circumferencial direction, the top of its piston rod is provided with projection, along its circumferencial direction open slot is set at middle die sleeve lower limb projection, open slot is corresponding one by one with hydraulic locking apparatus.
In the present invention, the radial action cylinder that vertical locking hydraulic cylinder that described hydraulic locking apparatus can evenly be provided with by the circumferencial direction along the lower shoe outer rim and corresponding level are installed is formed, displacement cylinder is connected with the locking hydraulic cylinder by its piston rod, and the locking hydraulic cylinder is moved back and forth along the radial direction of lower shoe.Swing locking hydraulic cylinder and corresponding wobbling action cylinder that hydraulic locking apparatus also can evenly be provided with by the circumferencial direction along the lower shoe outer rim are formed, the wobbling action cylinder is connected with the locking hydraulic cylinder by its piston rod, and the locking hydraulic cylinder is swung in vertical guide around its installation fulcrum.Hydraulic locking apparatus also can be for evenly the piston rod of setting can rotating locking hydraulic cylinder along the circumferencial direction in the lower shoe outer rim.The number of wherein locking hydraulic cylinder and the radial action cylinder corresponding with it is 3~60.The medium of locking hydraulic cylinder can be hydraulic oil or water, and the medium of displacement cylinder can be hydraulic oil, water or gas.
Between above-mentioned per two locking hydraulic cylinders, and the circumferencial direction along the lower shoe outer rim can evenly be provided with a plurality of clamping screws, the circumferencial direction correspondence of middle die sleeve lower limb projection open slot or through hole be set, make to form bolt between lower shoe and the middle die sleeve and connect.The quantity of the clamping screw that is provided with between per two locking hydraulic cylinders is 4~25, and in a vulcanizing equipment, the quantity of the clamping screw between per two locking hydraulic cylinders is identical.
Between described locking hydraulic cylinder, also the side set ring can be set, but will guarantee that per two quantity of locking the side set ring that is provided with between the hydraulic cylinders are identical in same the equipment.
In the present invention, the central authority of finalizing the design in the machine can be set in this equipment, also can central authority be set and outward by the machine fetus of finalizing the design.Steam chest is set respectively on upper cover plate and lower shoe, and steam chest and following steam chest in the formation constantly feed vapours in last steam chest and following steam chest, the tire base of putting into equipment is carried out baking; Also steam chest can be set, the heating of tire base be installed by other realize.
The invention has the beneficial effects as follows: mechanism by adopting the locking hydraulic cylinder not only to simplify vulcanization plant greatly as hydraulic locking apparatus in the direct vulcanizing equipment of heavy load radial tire, cancelled the use of vulcanizer, make whole vulcanizing equipment simple in structure, volume is little, in light weight, reduced equipment needed lifting force when the folding mould greatly, and realized the auto lock of vulcanization plant, locking effect is good, shortened the locking time of vulcanizing equipment, improve production efficiency, and can save great amount of manpower and material resources, reduced the production cost of tire.In the direct vulcanizing equipment of heavy construction radial, by adopting the locking hydraulic locking cylinder, bolt provides coupling mechanism force for mould, guaranteed the locking effect of vulcanizing equipment, when locking, at first utilize the locking hydraulic locking cylinder simultaneously, bolt is arranged between lower shoe and the middle die sleeve then, has made things convenient for the setting of bolt.
