Problems solved by technology

Most of the products on the market now, the synchronization accuracy of the double-cylinder system is low, and the quality of the sheared sheet is poor
[0003]Patents 200620158152.5 and 201120154346.9 disclose a hydraulic system of a gate shearing machine, both of which use serial hydraulic cylinders to ensure the synchronization of shearing sheets, but due to the lack of oil supply device, the synchronization accuracy is not high, and cannot well meet the synchronization control requirements of large shearing machines

Abstract

A dual output shaft motor based shear plate synchronous control hydraulic system relates to a plate shear synchronous control hydraulic system. The dual output shaft motor based shear plate synchronous control hydraulic system comprises two shear cylinders, two stock stopping cylinders, three pressing cylinders and a shear cylinder synchronous control system, wherein the shear cylinder synchronous control system comprises an oil tank, two same hydraulic pumps, a dual output shaft motor for driving the two hydraulic pumps to rotate, and two first check valves; an oil outlet of each first one-way valve is connected with a first oil way, a second oil way and a third oil way respectively, the first oil way comprises a pilot operated compound relief valve and a two-position two-way electromagnetic valve, the second oil way comprises a sequence valve and a two-position four-way electromagnetic valve, the third oil way comprises a reducing valve, a second check valve and a first energy accumulator, the dual output shaft motor drives the two same hydraulic pumps to supply oil for the two same shear cylinders, so as to better guarantee the synchronous accuracy of the two shear cylinders, and the two shear cylinders are respectively connected with the first energy accumulator to maintain the pressure.

Description

technical field [0001] The invention relates to a hydraulic system for synchronous control of a shearing machine, in particular to a hydraulic system for synchronous control of a shearing machine based on motors with double output shafts, and is especially suitable for the hydraulic system of double-cylinder high-precision synchronous control of a large shearing machine. Background technique [0002] At present, the shearing machine is very popular at home and abroad, and the size of the shearing plate is getting larger and larger, and most of them adopt hydraulic transmission. Most of the large-scale shearing machines use a double-cylinder system to shear the sheet, so the synchronous control accuracy of the double-cylinder system is particularly important, which is an important measure of product performance. Most of the products on the market now have low synchronization accuracy of the double-cylinder system, and the quality of the sheared sheet is poor. [0003] Patent...
