Embodiment 1
[0033] Such as figure 1 As shown, the hydraulic system of a gate-type shearing machine in this embodiment includes an oil tank 1, an oil pump 5, an electromagnetic overflow valve I8, an on-off valve 10, a sequence valve 11, an accumulator 14, a return cylinder 15, and a pressure cylinder 16. Main oil cylinder 18, auxiliary oil cylinder 19 and check valve II 21. Wherein, the piston rods of the main oil cylinder 18 and the auxiliary oil cylinder 19 are connected to the knife rest, and are used to drive the knife rest to move downward to complete the shearing of the plate. The auxiliary oil cylinder 19 adopts a plunger cylinder, and the return oil cylinder 15 is connected with the knife rest. It is used to drive the tool holder upward to make a return movement.
[0034] The oil tank 1 is equipped with a liquid level gauge 2 to monitor the liquid level in real time to prevent insufficient hydraulic oil and to replenish it in time. The oil tank 1 communicates with the air through ...

The invention discloses a hydraulic system of a brake type plate shearing machine and belongs to the technical field of hydraulic machines. A main oil cylinder, an auxiliary oil cylinder and a return oil cylinder of the hydraulic system are all connected with a knife rest. An oil suction port of an oil pump is connected with an oil tank, and an oil outlet of the oil pump is connected with an inlet of a sequence valve. An outlet of the sequence valve is connected with the main oil cylinder. An inlet of an electromagnetic overflow valve I is connected with the oil outlet of the oil pump. An outlet of the electromagnetic overflow valve I is connected with the oil tank. A rod cavity of the main oil cylinder communicates with a rodless cavity of the auxiliary oil cylinder and is connected to the oil outlet of the oil pump through a switching valve. A stop valve II is arranged on a pipeline enabling the switching valve and the main oil cylinder to be connected. An energy accumulator is connected with the oil outlet of the oil pump through a stop valve I and also connected with a rod cavity of the return oil cylinder, and a rodless cavity of the return oil cylinder communicates with air. Compared with an existing hydraulic system, the structure is greatly simplified, and the production cost is reduced; system operation is stable, and various operation requirements can be met; the pressing motion can be controlled independently, and the pressure can be controlled; and maintaining is convenient.
Description
technical field [0001] The invention belongs to the technical field of hydraulic machines, and more specifically relates to a hydraulic system of a gate-type shearing machine. Background technique [0002] The plate shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to the other blade to cut the plate. It uses the moving upper blade and the fixed lower blade to apply shear to metal plates of various thicknesses with a reasonable blade gap. Force, so that the plate is broken and separated according to the required size. The shearing machine is divided into mechanical shearing machine and hydraulic shearing machine. The thickness of the steel plate that the mechanical shearing machine can cut is generally less than 10mm, while the hydraulic shearing machine is mostly used to cut the steel plate above 6mm. Hydraulic shearing machine is divided into pendulum shearing machine and gate shearing machine. Compared with pendulum shearing...
