Problems solved by technology

In order to ensure the high-strength crushing and shearing capacity of the hydraulic shears, the cylinder volume of the hydraulic shears is very large, so it takes a long time for the hydraulic shears to complete the opening and closing process, and the work efficiency is not high
However, in the actual use process, when the hydraulic shear completes a single closing operation, there is a long period of no-load or light-load process; how to accelerate the closing speed of the hydraulic shear cylinder in the process of no-load or light load, so that Improving the working efficiency of hydraulic shears as a whole has become an urgent problem to be solved

Abstract

The invention relates to an oil cylinder control system for a hydraulic shear. The oil cylinder control system comprises an oil pump and an oil cylinder which are connected through a valve bank, the valve bank comprises a reversing valve, an oil separator and an integrated valve, the oil pump is connected with the reversing valve, the reversing valve is also connected with the oil separator, the oil separator is further connected with the integrated valve, the integrated valve is also connected with an oil tank, the oil inlet end of the oil pump is connected with the oil tank, and the oil outlet end of the oil pump is connected with the reversing valve; the oil cylinder comprises rod cavities and rodless cavities, an oil outlet of the reversing valve is communicated with an oil inlet of the oil separator, oil outlets of the oil separator comprise a first oil outlet and a second oil outlet, the first oil outlet is connected with the two symmetrically-arranged rodless cavities of the oil cylinder through oil pipes, and the second oil outlet is connected with the rod cavities of the oil cylinder through the integrated valve; the working efficiency is higher; and the invention further relates to the hydraulic shear comprising the above control system.

Description

technical field [0001] The invention relates to an oil cylinder control system for hydraulic shears and hydraulic shears, belonging to the technical field of fluid transmission and hydraulic control. Background technique [0002] At present, the widely used double-cylinder hydraulic shears are mainly used in the fields of building demolition, fire rescue, concrete and steel structure cutting, etc. In order to ensure the high-strength crushing and shearing capacity of the hydraulic shears, the cylinder volume of the hydraulic shears is large, so it takes a long time for the hydraulic shears to complete the opening and closing process, and the work efficiency is not high. However, in actual use, when the hydraulic shear completes a single closing operation, there is a long period of no-load or light-load process; how to accelerate the closing speed of the hydraulic shear cylinder in the process of no-load or light load, so that Overall improvement of the working efficiency of...
