Abstract

The invention discloses a bending method of a high-efficiency bending machine and belongs to the technical field of bending machines. In the present invention, the oil inlet of the oil pump is connected to the oil tank, and the oil outlet of the oil pump is connected to the P port of the three-position four-way electromagnetic reversing valve through a pipeline; the T port of the three-position four-way electromagnetic reversing valve is connected to the oil tank through a pipeline. Connected, the A port of the three-position four-way electromagnetic directional valve is connected to the lower chamber of the hydraulic cylinder through the superimposed valve group, and the B port of the three-position four-way electromagnetic directional valve is connected to the upper chamber of the hydraulic cylinder through the superimposed valve group. The upper chamber of the hydraulic cylinder is also connected to the energy accumulator through a hydraulically controlled one-way valve. By improving the hydraulic system of the bending machine, the present invention can efficiently control the entire process of plate bending: fast lowering, working advance, pressure maintaining, and pressure relief, ensuring high speed and stability in the fast lowering stage and stability in the working advanced stage. Stability and good pressure-holding effect. The oil pressure in the upper chamber of the cylinder is stable during the pressure-holding stage, thus ensuring the bending quality of the plate.
