Description

Rear inflation overturning and positioning device

Technical Field

Background

The post-inflating device is used for timely inflating, cooling and shaping the semi-steel tire with a high tire body temperature after vulcanization so as to keep the correct size and physical characteristics of the tire and avoid tire deformation, and is an important component of a semi-steel tire vulcanizer. The structure and performance of the post-inflation device directly affect the manufacturing cost and the final using effect of the vulcanizing machine, and also affect the structural size and the vulcanizing quality of the tire.

The turnover four-station rear inflating device is commonly used for a semisteel hydraulic vulcanizing machine, and a turnover centering structure of the turnover centering device usually adopts a hydraulic cylinder to drive a gear rack structure to drive a turnover device to perform turnover action. The positioning of the rim distance adjusting device is realized by the pressure of the hydraulic cylinder and the hard limiting structure of the turnover device, the operation is unstable, and the overall performance of the equipment is affected. Because hydraulic oil cylinder, hydraulic pressure pipeline exist in the inflation after the hydraulic drive is overturn-type, there is the potential safety hazard of hydraulic oil leakage. When hydraulic oil leaks, the oil pressure cannot be kept, so that the rim distance adjusting device cannot be accurately positioned, the upper and lower chucks after inflation cannot be locked, and the equipment cannot be used. More serious, the leaked hydraulic oil drops to a high-temperature steam pipeline below, and oil smoke is generated to cause fire, so that fire safety accidents are possibly caused.
