Description

technical field [0001] The invention relates to the technical field of numerical control bending machines, in particular to a high-precision oil-electric hybrid electro-hydraulic servo numerical control bending machine. Background technique [0002] The bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a worktable and a clamping plate. The worktable is placed on the bracket. The worktable is composed of a base and a pressure plate. The base is composed of a seat shell, a coil and a cover plate, the coil is placed in a recess of the seat shell, and the top of the recess is covered with a cover plate. When in use, the coil is energized by the wire, and after the electricity is energized, the pressure plate is gravitationalized, so as to realize the clamping of the thin plate between the pressure plate and the base. At present, bending machine products are widely used in: electromechanical, sheet metal, light industry, aviation, s...

AI Technical Summary

Problems solved by technology

Due to the application of the principle of proportional servo throttling and speed regulation, the energy loss is large and the system is prone to heat, so the energy utilization rate is low, and the ordinary hydraulic system also has a lot of noise when it is idle and fast.

[0004] In addition, one of the mechanical auxiliary devices often used on the bending machine is the back gauge device. The traditional back gauge device has poor positioning accuracy in the sheet metal forming process, and the operation is cumbersome and inconvenient to use. In the bending process, the work efficiency is poor, and in the process of bending workpieces of different sizes and specifications, it takes a long time, which is not conducive to production
