DIRECT ACTING MECHANISM OF TIRE CURING DEVICE AND CENTRAL MECHANISM OF TIRE CURING DEVICE

摘要

Provided is a direct acting mechanism of a tire curing device which can sufficiently perform positional control of a bladder extension height and a shaping height, etc., and is applicable to tires of different sizes. A hydraulically-driven central mechanism 1 as an example of a central mechanism of a tire curing device to which the present invention is applied includes a bag head 2 and a hydraulic cylinder 3. A cylinder tube 4 is formed to be thick-walled, and near the outer circumferential surface thereof, a sensor hole portion 7 is provided. The sensor hole portion 7 penetrates to the bottom surface side of the cylinder tube 4, and a linear sensor 8 with heat resistance and flexibility is inserted therein.

主权项

1: A direct acting mechanism of a tire curing device, comprising:
a clamp portion capable of clamping a bladder that can expand and contract; a thick-walled cylinder that is disposed below the clamp portion and formed into a hollow shape; a center post rod that is disposed in the hollow region of the cylinder, is movable in the vertical direction, and has an upper end attached to the clamp portion; a sensor portion disposed in a hole portion which is provided in a region between the inner circumferential surface and the outer circumferential surface of the cylinder, the opening of which penetrates to the bottom surface side of the cylinder, and capable of detecting magnetism; and a magnetic magnet portion attached to the center post rod.
