Center mechanism capsule height control device and method for tyre vulcanizer

Abstract

The invention discloses a center mechanism capsule height control device and method for a tyre vulcanizer. The device comprises a center mechanism, a pressure water cylinder assembly and a control assembly. The center mechanism comprises a cylinder body and a lifting rod. The lifting rod is sleeved with the cylinder body in a vertical sliding manner. The top of the lifting rod is used for being connected with an upper ring. The bottom end of the lifting rod stretches out of the cylinder body. The pressure water cylinder assembly comprises a pressure water cylinder and a piston rod. One end ofthe piston rod is slidably embedded into the pressure water cylinder. The other end of the piston rod is connected to the bottom of the lifting rod. The internal space of the pressure water cylinder is divided into a first cavity and a second cavity by the piston rod. According to the center mechanism capsule height control device for the tyre vulcanizer, due to the fact that the pressure water cylinder and the cylinder body are designed separately, that is, the pressure water cylinder is independently arranged below the cylinder body, the problem that the pressure water in the pressure watercylinder enters a capsule, and the vulcanization effect of a tyre is reduced is avoided.

Description

technical field [0001] The invention relates to the field of tire vulcanizing machine equipment, in particular to a device and method for controlling the height of a central mechanism bladder of a tire vulcanizing machine. Background technique [0002] The tire vulcanizer is a mechanical device for clamping and vulcanizing the tire blank during the tire production process; the central structure of the tire vulcanizer is its core structure, and the central structure generally includes a bladder, an upper ring, a lower ring and a lifting rod; The upper end and the lower end are respectively sealed and connected to the upper ring and the lower ring; the upper ring and the lower ring are respectively connected to the lifting rod; Filling the inside of the tire blank and separating it from the tire blank, the bladder is filled with high-pressure gas, and the high-pressure gas enables the bladder to extrude the tire blank to complete the vulcanization operation. [0003] In the c...
