Today, I bring you some questions about the main causes of active and passive anti-bias of electro-hydraulic servo CNC bending machine and related introduction. I hope to help some friends who want to know about active and passive anti-bias of electro-hydraulic servo CNC bending machine.
Strong anti-eccentric load capability is one of the characteristics of electro-hydraulic servo CNC bending machine. Working principle: When the grating ruler on one side of the cylinder detects displacement, the position parameters are transmitted to the CNC system. After the system distinguishes the data of two grating rulers, more oil is added to the cylinder on the offset position through the hydraulic proportional valve, so as to achieve two cylinders. The purpose of synchronization.
Let’s suppose what happens when one side of the machine is bent (i. E. unbalanced load)?

Through the principle, we can see that the electro-hydraulic servo CNC bending machine will only give more pressure to the cylinder on the side of unbalanced load, while the cylinder on the other side will hardly be pressurized. That is to say, only half of the hydraulic pressure can be obtained under unbalanced load, such as 110 tons of bending machine, when unbalanced load, the maximum pressure can not exceed 50 tons, thus minimizing the distance of the bending machine frame. This is the intelligent anti-bias working principle of electro-hydraulic servo CNC bending machine.
Because of the synchronous structure of torsion axis, the working pressure of the cylinders on both sides is balanced. For example, the working pressure of 110 tons bender is still 110 tons under eccentric load. When encountering eccentric load, the torsion synchronization device needs to bear all the deviation energy of the other side of the cylinder. The thicker the plate, the greater the deviation energy produced, and the biggest damage in the whole process is the torsion synchronization device. This is the working principle of passive anti-bias.
Above is the detailed description of active and passive anti-bias of electro-hydraulic servo CNC bending machine. For more information about active anti-bias and passive anti-bias of electro-hydraulic servo CNC bending machine, please consult Shengda Heavy Industry SDMT customer service.
