Oil-electric hybrid hydraulic system of energy-saving environment-friendly electro-hydraulic numerically controlled synchronous bending machine

Abstract

The invention discloses an oil-electric hybrid hydraulic system of an energy-saving environment-friendly electro-hydraulic numerically controlled synchronous bending machine. The system comprises an oil tank, an oil pump, a high performance servo motor and a speed-increasing cylinder. One side of the inner wall of the oil tank is fixedly connected to one side of the oil pump, and one side of the oil tank is fixedly connected to one side of the high performance servo motor. The invention relates to the technical field of hydraulic control of bending machine. According to the oil-electric hybridhydraulic system of the energy-saving environment-friendly electro-hydraulic numerically controlled synchronous bending machine, based on a structure of a oil-electric hybrid oil cylinder and matchedwith a single servo pump, use of electric appliance power equipment such as the oil pump and a motor can be achieved, so that a purpose of an oil-electric hybrid intelligent control hydraulic systemis achieved. Compared with a conventional hydraulic system of the bending machine, over 75% electric quantity is saved, and over 100 L of oil is consumed within a unit time. The oil-electric hybrid hydraulic system only consumes less than 30 L of oil within the unit time and meanwhile, the oil-electric hybrid hydraulic system is simple and compact in structure.

Description

technical field [0001] The invention relates to the technical field of hydraulic control of a bending machine, in particular to an oil-electric hybrid hydraulic system of an energy-saving and environment-friendly electro-hydraulic numerical control synchronous bending machine. Background technique [0002] With the rapid development of social economy, the improvement of mechanization level has brought various conveniences to people's life. Among them, the bending machine is widely used in the plate industry. The bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate through a hinge. In the recess of the seat shell, the top of the recess is covered with a cover plate. When in use, the wire is energized to the coil, and after the electrification, the pressure pla...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an oil-electric hybrid hydraulic system of an energy-saving and environment-friendly electro-hydraulic numerical control synchronous bending machine, which solves the problem that the existing hydraulic system of the bending machine can only save a certain degree of electric energy, and the energy-saving effect is not significant. It is not obvious. It also needs to consume the same volume of oil, which cannot achieve the effect of environmental protection. The double servo pump will also produce noise during the operation of the servo motor, which cannot achieve a large degree of noise reduction. At the same time, it is compatible with the double servo pump. The multi-piston speed-increasing cylinder used has a complex structure and a relatively large volume, which is inconvenient for people to assemble and use
