Tire forming vulcanizer C type central authority

The utility model relates to a kind of C type capsule manipulation device of car tyre bimodulus typing mechanical type vulcanizer.

Tire forming vulcanizer is mainly used in the tyre sulfuration of air core tyre, and it can be finished dress tire, typing, vulcanize, unloads series of processes such as tire and back inflation.Is that the extensive use of present doughnut manufacturing industry also is to use the maximum a kind of process equipment of quantity with crank one linkage as the mechanical type bimodulus shaper vulcanizer of main drive gear, it mainly is made up of frame, vaporium, central authority, elevating mechanism, loading tire mechanism, disassembling mechanism of tyre and transmission mechanism etc., wherein central authority claims the capsule manipulation device again, it is the cardiac component of vulcanizer, its effect is to pack in the fetus capsule and typing before the sulfuration, the sulfuration back is extracted capsule out from tire, make the tire demoulding etc.The central authority of mechanical type tire forming vulcanizer has four kinds of forms at present: 1, by the Autoform type (China is called for short the A type, and Japan is called for short the Bagwell type) of U.S. NRM company exploitation, be mainly used on the car tyre twin mold shaping curing press; 2, by the Bag-O-Matic type (China is called for short Type B) of U.S. Mcneil company exploitation, be mainly used on the bimodulus or single mode vulcanizer of car tyre, heavy sevice type and engineering tire; 3, by the Rolling in Bladder type (China is called for short the RIB type) of Mitsubishi heavy industry Co., Ltd. exploitation, be mainly used on the car tyre twin mold shaping curing press; 4, by the AuBo type (China is called for short AB type or C type) of German Her-Bert company exploitation, on the LL-C1400X2940X2 load-carrying tire twin mold shaping curing press that current is applied to by Zhanjiang Machine Factory, Guangdong Prov.'s Development and Production.Only with regard to riding tire bimodulus typing mechanical type vulcanizer, employed A type, all there are weak point in RIB type and Type B central authority in actual production: the capsule of A type central authority is that collection downwards is folded in the storage capsule tube, it releases relatively difficulty of capsule, when typing, because no center stand column in the capsule, inflation along with capsule, tire base bottom can move up, may produce capsule and fill in the inhomogeneous little crooked phenomenon in big one side that occurs of tire base on one side, can not guarantee the coaxial accuracy requirement of tyre bead up and down reliably, when vulcanizing in addition, curing medium must be full of whole capsule tube, and consumes a large amount of energy; Though RIB type central authority has overcome above-mentioned two shortcomings of A type central authority, but in order to finish the demoulding and to unload movement of the foetus and do, the ejector device that has still kept A type central authority in knockout course, just exists easy damage of ejector umbrella shape jig plate and tire bead and is drawn bad phenomenon easily; The capsule of Type B central authority is upwards pulled out, the capsule circumferencial direction exists very big elongation strain during typing, not only influence capsule service life, and cause the distortion of tire base also bigger, this radial-ply tyre vulcanized quality influence to all steel or half steel structure is very big, capsule must vacuumize when tire was unloaded in the demoulding in addition, had increased energy resource consumption.C type central authority structure and excellent performance by the exploitation of German Her-Bert company, on with the fluid pressure type shaper vulcanizer of hydraulic oil driving oil cylinder, obtain extensive use as main transmission structure, the world a few giant tyre vulcanizer manufacturing firm such as German Her-Bert company, Krupp company, Mitsubishi heavy industry Co., Ltd., U.S. NRM company etc. has all used C type central authority on the fluid pressure type shaper vulcanizer of its manufacturing, as a kind of trend, the tire forming vulcanizer of C type central authority should be the development in future direction, it is very few that yet the central authority of this excellent performance is used on the mechanical type vulcanizer, main cause is the restriction that is subjected to mechanical type vulcanizer base space, is difficult to determine a reasonable design scheme in the selection of version and assembling form.In 1994, Zhanjiang Machine Factory, Guangdong Prov. breaks through traditional thinking mode, successfully C type central authority is applied on the twin mold shaping curing press of LL-C1400 newly developed * 2940 * 2, and vulcanize the full steel wire heavy load radial tire that function admirable, proof C type central authority is used on the mechanical type shaper vulcanizer not only feasible but also respond well, but this C type central authority has also been found many problems in the actual production of Shiyan City, Hubei Province east wind tire group company is used: 1, the water inlet of newel water vat and titting water outlet all are positioned at the outer bottom of lifting capsule tube, the newel water vat with under encircle in the lifting process, import and export water pipe when passing lifting capsule tube bottom through hole, its joint is often cut off; 2, encircling lifting about is down realized by water vat cranker one linkage, this is similar to Type B central authority stripper apparatus because the limitation of this kind device self, about the ring lifting must synchronization action down, this is difficult to strict guarantee in actual production process, thereby causes the crank axis usually to be out of shape; 3, lifting capsule tube directly is sleeved under the vulcanizer in the floral disc through hole, and its guide ring is installed difficulty and is difficult to by the designing requirement strict guarantee with the tolerance fit of lifting capsule tube; When 4, changing the tyre sulfuration specification, must change the typing cover that is placed in the newel water vat, it is time-consuming to require great effort; 5, following ring lock block structure heaviness can't be adjusted when changing the tyre sulfuration specification; In sum, the structure of this C type central authority is incomplete.

The purpose of this utility model just is to avoid the weak point of above-mentioned four kinds of central authorities, and design a kind of rational in infrastructure, typing precision height, sulfuration cover tire quality is good, the demoulding is easy, is fit to the C type central authority that car tyre bimodulus typing mechanical type vulcanizer uses.
