Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0019] Such as figure 1 As shown, the bending machine uses fluid transmission to make the double cylinder drive the slider to move up and down. Its working conditions are: fast down, slow down, work down, pressure maintaining, pressure relief, and return.
[0020] refer to figure 2 , the electro-hydraulic proportional position synchronous control system of the bending machine of the present invention is composed of an oil tank 1, a filter 2, a quantitative pump 3...

An electro-hydraulic proportional position synchronous control system for a bending machine, which is composed of an oil tank, a filter, a quantitative pump, an overflow valve, a throttle valve, a central three-position four-way electromagnetic reversing valve, a cartridge valve, a two-position Two-way electromagnetic reversing valve, two-position three-way electromagnetic reversing valve, signal amplifier, hydraulic control check valve, one-way valve, hydraulic cylinder, three-position four-way electromagnetic proportional reversing valve and connecting pipelines between various components Composition, through the electro-hydraulic proportional position synchronous control system of the bending machine, the synchronous control of the computer-controlled bending machine's fast down, slow down, work down, pressure relief, and return processes is realized. It is precise and simple, which greatly improves the work efficiency and reduces the production cost. Through computer remote control, it solves the safety hazards caused by manual operation of operators.
Description
technical field [0001] The invention relates to an electro-hydraulic proportional position synchronous control system, in particular to an electro-hydraulic proportional position synchronous control system for a bending machine. Background technique [0002] Bending machine is a kind of precision general-purpose equipment for sheet metal bending and forming, which has been widely used in many fields. At present, most bending machines in China mainly use torsion axis synchronous block positioning, machine-hydraulic synchronous block positioning and other methods for synchronous control. The defect is that the response of the hydraulic cylinder is slow, which is not conducive to control, and it is hydraulic transmission. The structure is complex and the cost of use and maintenance is high. Judging from the effect of use, because remote control cannot be used, in some dangerous working conditions, manual adjustment is required, which brings safety hazards to the work of operat...
