Description

Closed-loop controlled electro-hydraulic servo bending machine

Technical Field

The utility model belongs to the technical field of bending machines, and in particular relates to an electro-hydraulic servo bending machine with closed-loop control.

Background Art

A bending machine is a machine that bends thin plates. An electro-hydraulic bending machine is a device that uses hydraulic pressure as a driving force to bend workpieces. Compared with traditional bending machines, it has better bending effects and higher bending precision. The hydraulic system of an electro-hydraulic bending machine includes power elements, actuators, control elements, auxiliary elements and hydraulic oil. Generally, the hydraulic cylinder converts the hydraulic pressure into mechanical force. After searching the application number "CN201822073544.7", it is recorded that "by setting two oil cylinders, a servo is set on each oil cylinder at the same time." The servo valve can make the downward pressure of the slider stronger and make the whole equipment more stable. The servo valve can accurately control the amount of oil, making the slider more sensitive. At the same time, it also improves the accuracy of the downward pressure depth of the bending knife, improves the accuracy of bending, avoids production waste, and reduces production costs. However, the device still has the following defects in actual use: the existing closed-loop controlled electro-hydraulic servo bending machine can only adjust the movement of the bending tool when in use, but it is not convenient to install and disassemble bending tools of different lengths, which limits the use of the device. Therefore, it is necessary to design a practical closed-loop controlled electro-hydraulic servo bending machine.
