Abstract

The invention provides a double-layer tire vulcanizer pressurization oil cylinder hydraulic control system comprising a hydraulic pump source, a control valve block and a pressurization oil cylinder which are connected through pipelines. The hydraulic pump source comprises an oil tank, a double oil pump, a first check valve, a second check valve and a third reversing valve. The control valve blockcomprises a third check valve and a first reversing valve. S1 and S2 openings of the double oil pump are both connected with the oil tank. A P1 opening of the double oil pump is connected with a DA opening of the first check valve. A DB opening of the first check valve is connected with a YP opening of the first reversing valve. A YA opening of the first reversing valve is connected with a rodless cavity of the pressurization oil cylinder. A P2 opening of the double oil pump is connected with an SP opening of the third reversing valve, and an SA opening of the third reversing valve is connected with a PA opening of the second check valve. A PB opening of the second check valve is connected with the rodless cavity of the pressurization oil cylinder. A rod cavity of the pressurization oil cylinder is connected with a YB opening of the first reversing valve. A YT opening of the first reversing valve is connected with a GA opening of the third check valve. A GB opening of the third checkvalve is connected with the oil tank.

Description

technical field [0001] The invention relates to the technical field of hydraulic control systems, in particular to a hydraulic control system for a pressurized oil cylinder of a double-layer tire vulcanizing machine. Background technique [0002] my country's rapid economic development in recent years, consumption upgrades and manufacturing industry upgrades have driven the vigorous development of the automobile industry, and the related tire industry has entered a period of rapid development. China has quickly become the world's largest tire producer and tire equipment manufacturer. However, due to its particularity, tire equipment occupies a large amount of land, and the soaring cost of domestic land has become a bottleneck restricting the development of the industry. The prospects are hindered and the pace is slow. It is urgent to use technology upgrades to promote industrial development and upgrades and break down barriers to industry development. In this context, a dou...
