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.

Abstract

The invention discloses an efficient energy-saving type oil-electric hybrid numerical control bending machine, and relates to the technical field of bending machine equipment. The problems of low energy utilization rate and high noise caused by high energy loss and prone in heating of a system of an existing bending machine are solved. The efficient energy-saving type oil-electric hybrid numerical control bending machine comprises a bending machine body, the bending machine body comprises an upper die and a lower die which are arranged up and down, the upper die is connected with a tool used for bending, and the lower die is connected with a positioning groove matched with the bending tool; the bending machine body is further connected with a driving device used for driving the upper die to move up and down, the driving device comprises an oil cylinder, and an output rod of the oil cylinder is connected with the upper die; and an oil tank is arranged in the bending machine body and communicates with an oil pump, the oil pump is connected with a servo motor, and the servo motor drives the oil pump to work, so that a piston rod of the oil cylinder acts. The effects that when a proportional valve and a direction valve are omitted for reversing, when a servo motor is started, the oil pump can be started approximately without pressure, the response speed is high, and the working efficiency is improved are achieved.

Description

technical field [0001] The invention relates to the technical field of bending machine equipment, in particular to a high-efficiency and energy-saving oil-electric hybrid numerical control bending machine. Background technique [0002] At present, the principle of the hydraulic control system of the electro-hydraulic servo synchronous bending machine at home and abroad is very similar, and it has basically remained unchanged for decades. It relies on the proportional servo valve to control the synchronization of the oil cylinder, which can be called a valve-controlled synchronous system. 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 large noise when it is idle and fast. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency and energy-sa...
