Hydraulic pressurization system and tire vulcanizer

Abstract

The invention relates to the field of tire forming, and discloses a hydraulic pressurization system and a tire vulcanizer. The hydraulic pressurization system comprises a hydraulic pump source, a control valve block and a pressurization oil cylinder, the hydraulic pump source supplies hydraulic oil to the pressurization oil cylinder through the control valve block, the pressurization oil cylinder comprises a cylinder barrel, a piston rod and a pressurization piston, the cylinder barrel is provided with a first cavity and a second cavity which communicate with each other, the piston rod is arranged in the first cavity in a sliding mode, the pressurization piston is slidably arranged in the second cavity, one end of the pressurization piston is a low-pressure end, the other end of the pressurization piston is a high-pressure end, the cross sectional area of the low-pressure end is larger than that of the high-pressure end, and the low-pressure end can drive the high-pressure end to pressurize hydraulic oil between the high-pressure end and the piston rod under pushing of the hydraulic oil so as to push the piston rod. An extra high-pressure pipeline is not needed, working efficiency and safety performance are improved, an extra high-pressure pump set does not need to be arranged, cost is saved, energy consumption is reduced, noise is reduced, a mechanism is simplified, and stability is improved.

Description

technical field [0001] The invention relates to the field of tire building, in particular to a hydraulic pressure boosting system and a tire vulcanizing machine. Background technique [0002] The hydraulic vulcanizer is the equipment used in the vulcanization process in the tire production process, and it is one of the key equipment that determines the quality of the tire. In the existing hydraulic vulcanizing machine, the actions of opening and closing the mold, increasing the clamping force, lifting and lowering of the central mechanism, expanding and contracting the movable mold, and lifting and lowering the tire loading mechanism are all realized by hydraulic transmission, which has fast response speed, reliable action and high efficiency, and can realize Stepless speed regulation, good performance, greatly reducing user operating costs and improving equipment utilization. [0003] The pressurization method of the existing hydraulic vulcanizer usually adopts the direct ...

AI Technical Summary

Problems solved by technology

When the high-pressure pump is used to directly pressurize, there are the following disadvantages: high-pressure pump and motor use cost, energy consumption and noise are relatively large, the cost of pipeline connection increases, and the leakage point of hydraulic oil also increases

When the superimposed supercharger is used, there are the following disadvantages: high price, unstable performance, and long import procurement cycle
