Description
Technical field
The utility model relates to a kind of moving shear quick pressure releasing hydraulic system.
Background technique
The shear action of guillotine shear makes knife rest increase or decline to realize shear action by oil cylinder fuel feeding and oil return, traditional hydraulic system is when pressure release, pressure release speed is slower, reduce working efficiency, in pressure leak process, because knife rest impacts large, larger noise can be produced, have impact on the stationarity of whole guillotine shear.
Model utility content
For above-mentioned defect, the purpose of this utility model is to provide a kind of quick pressure releasing, increases work efficiency, and impacts little, a kind of moving shear quick pressure releasing hydraulic system that noise is little.
The technological scheme that the utility model adopts for this reason is:
Comprise the oil cylinder being arranged on knife rest lower end, described oil cylinder is connected with oil feed pump by pipeline, described pipeline is provided with Pilot operated check valve, described Pilot operated check valve and the pipeline between oil cylinder are provided with the first return line and are connected with plug-in mounting throttle valve respectively with the second return line, described plug-in mounting throttle valve is connected with oil sump tank, described plug-in mounting throttle valve is connected with Solenoid ball valve, described second return line is provided with one-way valve, one-way throttle valve is provided with between described one-way valve and plug-in mounting throttle valve, described first return line is directly connected with oil sump tank by oil circuit, described oil circuit is provided with cartridge valve, described cartridge valve is connected with pressure valve, described pressure valve is connected with oil cylinder by pipeline.
Further, described first return line is provided with series flow control valve.
Further, the pipeline between described first return line and oil cylinder is provided with relief valve.
Further, described plug-in mounting throttle valve is the plug-in mounting throttle valve of band damping.
The utility model has the advantages that:
The utility model structure is simple, the hydraulic oil in oil cylinder can be made fast to get back in fuel tank, increase work efficiency, impact little, noise is low, Solenoid ball valve obtain electric after, the conducting of plug-in mounting throttle valve, hydraulic oil is got back to oil sump tank from the first return line and the first return line through plug-in mounting throttle valve respectively; When the pressure of pressure valve is reduced to a certain degree, cartridge valve is directly communicated with oil sump tank, and one-way valve is communicated with plug-in mounting throttle valve, completes the action that oil sump tank got back to rapidly by hydraulic oil.
Accompanying drawing explanation
