Problems solved by technology
When a high mechanical output force is required, the area of the piston is increased, but the working speed is reduced; for the condition of high-speed work, the area of the piston is reduced, but the mechanical output force often does not meet the requirements.
[0004] At present, the industry generally adopts the highest flow requirements to design, and the working requirements are met by increasing the flow of the pump or adding an accumulator, but this is not only less effective, but also consumes a lot of energy.

The invention discloses a fast oil cylinder with two-way adjustable output force, which belongs to the technical field of oil cylinders of hydraulic components. Its function is to greatly increase the working speed of the oil cylinder without increasing the flow rate of the system. The oil cylinder is mainly composed of an oil guide rod, a main oil cylinder assembly and a booster cylinder assembly. It is characterized in that the oil guide rod is fixed on the back cover of the main oil cylinder, connected and sealed with the hollow piston rod, and the first oil hole is provided, the main oil cylinder is provided with the second and third oil holes, and the booster cylinder assembly is also provided with a vent hole. The second oil hole is connected to the reversing valve and connected to the filling valve. The invention realizes greatly improving the working speed of the oil cylinder without increasing the flow rate of the system.
Description
technical field [0001] The invention relates to a fast oil cylinder, in particular to an oil cylinder that provides adjustable output force in both directions at the stroke end and works quickly in both round and round strokes. Background technique [0002] As we all know, hydraulic cylinders, as commonly used hydraulic components in hydraulic systems, are widely used in various industries such as machine tools, metallurgy, mining, chemical industry, ships, automobiles, hydropower, etc. [0003] In the prior art, for a certain hydraulic system, there is a contradiction between the speed and the output force of the oil cylinder. When a high mechanical output force is required, the area of the piston is increased, but the working speed is reduced; for the condition of high-speed work, the area of the piston is reduced, but the mechanical output force often does not meet the requirements. [0004] At present, the industry generally adopts the highest flow requirements to d...
