Description of the Invention: [Technical Field of the Invention] [Prior Art] The present invention relates to a tire building drum for establishing an unvulcanized tire by a rubber tire component, wherein the tire building drum comprises a drum shaft and two a drum half, the two drum halves being configured to be at least substantially symmetrical about a center of the tire building drum and surrounding the drum shaft, the two drum halves being movable in the axial direction along the drum shaft, each drum half The body includes a folding arm single, the folding arm unit having a plurality of folding arms rotatably coupled to the associated drum half. EP-B1-1.439.054 discloses a tire building drum comprising a base shaft for a folding unit for a hollow second shafting of a bead core clamping unit Coaxially arranged around the base shaft. The base shaft can be coupled to the hollow second shaft by a coupling such that the two shafts can be coupled to each other (to move the entire drum half) or to be detached from each other. Although for the other tire building drum using a pneumatic actuator on the folding arm carrier, the above-mentioned conventional tire drum has a significant improvement in the synchronous lifting of the folding arm unit due to the special use of the base shaft. Such a tire building drum still has the disadvantages described below. For example, the coupling described above is not only a relatively expensive and complicated extra part, but also tens of damage, the coupling is difficult to repair. Further, since the two coaxially disposed shafts ' are used in the drum shaft, the entire tire building drum is quite long and [Explanation] 4 201109166 The present invention is directed to a month for establishing an unvulcanized tire. The forming drum' is easy to maintain and can be designed to be smaller. In order to achieve the above object, the present invention provides a tire building drum for establishing an unvulcanized tire, characterized in that the tire building drum comprises a main casing, the drum shaft protruding from the main casing, wherein four push rods Arranging in the drum shaft, the push-pull rods are movable in the axial direction and extend into the main casing, and are connected to a driving mechanism in the main casing; wherein the first four of the four push-pull rods The push-pull rod is connected to the first drum half, the second push-pull rod of the four push-pull rods is connected to the second drum half, and a third push-pull rod of the four push-pull rods is connected to the first drum The half-body folding arm unit, and a fourth push-pull rod of the four push-pull rods are connected to the second boom unit. Accordingly, the tire building drum of the present invention is provided with an external actuation = for moving the drum halves and flipping the folding arms upwards, the actuators :: placed outside the drum shaft. In this way, it is no longer necessary to place the shaft in the shaft, so the tire building drum can be designed to be smaller and easier to repair. ^ In the detailed example, the four push rods are placed concentrically in the fulcrum. The external drive mechanism is connected by means of four tubular push-pull rods: a drum half and its folding arm unit, which can be arranged concentrically and preferably placed on the centerline of the drum shaft.
