A tire support device includes: a first rim support portion; a second rim support portion which is provided so as to oppose the first rim support portion; a frame which includes a guide which movably guides the second rim support portion in a direction approaching or separating from the first rim support portion; a transport portion which is movably attached along the guide; a drive portion which moves the transport portion along the guide; an engagement mechanism which can engage with the frame at a retreat position at which the second rim support portion is separated from the first rim support portion; and a supported portion which integrally supports the second rim support portion and the transport portion in a movable manner along the guide in a state where engagement with the engagement mechanism is released.

Tire support device and tire cooling system

A tire vulcanizer system in which multiple tire vulcanizers, provided with a frame and a vulcanizing mechanism that is supported by the frame and is for vulcanizing green tires, are connected, wherein the tire vulcanizers are provided with respective alignment sections, which are provided on the respective frames and are for aligning the level positions of adjacent frames relative to each other.

Tire vulcanizer system and assembly method therefor

Provided are a tire vulcanizer and a method for transporting or packaging the same whereby, even in cases where the overall height direction dimension of the vulcanizer exceeds size limits for domestic transportation or export packaging, the vulcanizer can easily clear said limits and be transported or packaged. A tire vulcanizer comprising tie rods extending upward from a base plate, said tie rods receiving squeezing force applied to a bolster plate and a top mold when vulcanizing a tire and guiding lifting/lowering of the bolster plate and the top mold when opening and closing the top mold. In such a tire vulcanizer, the tie rods are configured so as to be vertically dividable into at least two or more sections at a position in the length direction thereof.

Tire vulcanizer and method for transporting or packaging the same

In a vulcanizing system of the present invention, a temperature booster and a pressure booster are provided on a steam supply path connecting vulcanizers that belong to groups and a boiler allocated to the groups. The temperature booster and the pressure booster are sequentially arranged from an upstream side, a second branch supply path for supplying the steam to a mold between the temperature booster and the pressure booster is branched from the steam supply path. The second branch supply path is preferably in a form of allowing the steam temperature-boosted by the temperature booster to be supplied to the mold by bypassing the pressure booster.

Vulcanizing system

In a center mechanism of a tire vulcanizing machine, including an upper clamp ring for grasping an upper opening end part of a bladder, a lower clamp ring for grasping a lower opening end part of the bladder, a hub on a side of a lower mold for supporting the lower clamp ring, a spacer connected to the hub and supported on the side of the lower mold to be ascendable and descendable, and a center post supported by the spacer to be extensible and contractible, the hub and the spacer are formed as members separate from each other, and are divisibly bound to each other by bolts.

Center mechanism of tire vulcanizing machine

A bead ring locking mechanism restricts the relative turning of a tubular lifter moved upward or downward on the outside of a central mechanism outer casing with respect to an annular bead ring attached to the outer circumference of the lifter to form a part of a die. The locking mechanism includes a stopper member installed at the bead ring and attached so as to move back and forth with respect to the lifter, and an actuating member which moves the stopper member from the bead ring to the lifter. A recessed portion is formed at the lifter, a raised portion is formed at the stopper member, and the raised portion is fitted into the recessed portion by pressing the stopper member to the lifter using the actuating member.
