Description
Technical Field
The utility model relates to a hydraulic pressure technical field, a closing device's actuating system specifically says so.
Background
The continuous heating furnace is used for carrying out heat treatment on the steel plate, and the heat-treated steel plate is heated unevenly and inevitably has a warping phenomenon, so that a subsequent pressing and shaping process is required. The existing pressing device is driven by hydraulic pressure, a plurality of groups of pressing oil cylinders are used for driving pressing blocks to move up and down, each pressing oil cylinder is connected with a high-pressure oil pump through a pipeline, and the high-pressure oil pump is far away from the pressing oil cylinders, so that the length and the shape of a communication pipeline of each pressing oil cylinder are inconsistent, pressure loss is caused, the stroke and the pressing force of pistons of the pressing oil cylinders are different, and finally the shaping effect of a steel plate is poor.
Disclosure of Invention
In order to solve the technical problem, the utility model aims at providing a hydraulic system that pressure is even, concrete technical scheme is as follows:
a hydraulic driving system of a steel plate arranging and pressing device comprises a high-pressure oil pump, wherein the oil inlet end of the high-pressure oil pump is communicated with an oil storage tank, and the oil outlet end of the high-pressure oil pump is communicated with a pressure equalizing oil cylinder and a plurality of pressing oil cylinders through a three-way valve; the uniform oil cylinder comprises a cylinder body and a piston, wherein one end, above the cylinder body, of the piston rod is an oil inlet end, and the cylinder body below the piston is a pressure equalizing end; the pressing oil cylinder comprises a piston end and an oil storage end, and the pressure equalizing end is communicated with the oil storage end through a pipeline; the piston end is communicated with the three-way valve through a first main pipeline after being communicated through a pipeline, and the first main pipeline is also connected with the oil storage tank through a first opening and closing valve; and the oil inlet end of the pressure-equalizing oil cylinder is communicated with the three-way valve through a main pipeline II, and the main pipeline II is also connected with the oil storage tank through an opening and closing valve II.

The piston ends of the adjacent compression oil cylinders are communicated through a pipeline.
The open-close valve and the three-way valve are both electrically operated valves and are connected with the console.
And filter screens are arranged at the joints of the main pipeline I and the main pipeline II and the oil storage tank.
The open/close valve and the three-way valve may be commercially available products, such as those from the Shanghai Bokkel valve plant.
The principle of the utility model is that: when in compression, the port of the three-way valve and the port of the main pipeline I11 are closed, the port of the main pipeline II 14 is opened, the opening and closing valve I12 is opened, and the opening and closing valve II is closed, high-pressure oil pumped by the high-pressure oil pump 1 enters the oil inlet end 7 of the pressure equalizing oil cylinder, the piston 6 moves downwards under the action of the high-pressure oil to push hydraulic oil at the pressure equalizing end to act on the piston of the compression oil cylinder to move outwards, and meanwhile, the hydraulic oil at the piston end of the compression oil cylinder flows back to the oil tank through the main; the opposite is true when lifted.
