Abstract

The invention discloses a bending method of an efficient bending machine, and belongs to the technical field of the bending machine. An oil inlet of an oil pump is connected with an oil tank; an oil outlet of the oil pump is connected with a port P of a three-position four-way electromagnetic directional valve through a pipeline; a port T of the three-position four-way electromagnetic directional valve is connected with the oil tank through a pipeline; a port A of the three-position four-way electromagnetic directional valve is connected to an upper cavity of a hydraulic cylinder through a superposing valve set; a port B of the three-position four-way electromagnetic directional valve is connected to the upper cavity of the hydraulic cylinder through a superposing valve set; the upper cavity of the hydraulic cylinder is further connected with an energy accumulator through a hydraulic-control one-way valve. By improving a hydraulic system of the bending machine, the whole plate bending process of quickly descending, feeding, maintaining pressure and decompressing is efficiently controlled, high speed and stability of the quick descending stage as well as stability of the feeding stage are guaranteed; and meanwhile, the pressure maintaining effect is good, and the oil pressure of the upper cavity of the oil cylinder at the pressure maintaining stage is stable, so that the bending quality of plates is guaranteed.
