Abstract
The utility model discloses a hydraulic system of a one-armed hydraulic machine. The hydraulic system comprises a fuel tank. A liquid level meter is arranged on one side of the fuel tank. An oil absorption filter, an air filter, an electric contact thermometer and an air cooler are mounted on the fuel tank. The oil absorption filter is connected to a vane pump through a pipeline. The vane pump is connected with a motor through a coupler. A one-way valve is in parallel connection with the air cooler. The other end of the air cooler is connected with an overflow valve, a remote pressure regulating valve and a first solenoid directional valve respectively through pipelines. The other end of the overflow valve is connected with the other end of the vane pump through a pipeline. The two ends of the first solenoid directional valve are connected with an upper cavity of an oil cylinder and an overlaid throttle valve respectively through pipelines. The overlaid throttle valve is connected with a second solenoid directional valve which is connected with a lower cavity of the oil cylinder through a pipeline. The upper cavity and the lower cavity of the oil cylinder are respectively connected with one solenoid directional valve, so that the whole hydraulic system is smooth in transmission; by the adoption of the air filter, the air cooler and the like, the performance of the hydraulic system is enhanced, and the using effect is good.
Description
Technical field
The utility model relates generally to the single arm hydrodynamic press field, relates in particular to a kind of hydraulic system of single arm hydrodynamic press.
Background technology
Single arm hydrodynamic press, fuselage are C type single arm type structure, adopt submerged arc welding, pass through vibration processing after welding, to guarantee the indeformable degree of fuselage.Hydraulic system is positioned at fuselage, and is aesthetic in appearance, easy to operate.Mainly be applicable to the techniques such as metallic article stretching, moulding and compacting, but also machining of non-metallic material, the compacting of sintered metal product, the correction of axial workpiece, the press-fiting and the technique such as shaping of metallic article, trimming of cover parts.Single arm hydrodynamic press is hydraulic oil distribution to be arrived epicoele or the cavity of resorption of oil cylinder by each check valve and overflow valve, under the effect of hydraulic oil, oil cylinder is moved.Hydraulic press is to utilize liquid to come the equipment of transmission of pressure.Liquid is to follow Pascal's law during transmission of pressure in airtight container, needs that research and development are a kind of is fit to the hydraulic system that domestic single arm hydrodynamic press uses.
