The so-called electro-hydraulic servo press brake bending machine is a hydraulic bending machine. Different from other similar products, it can carry out intelligent control, fully automatic production, as well as the application with the manipulator. At the same time, it can be installed directly on the electrical cabinet or in the hanging cabinet. Let’s take a closer look at “the characteristics of the electro-hydraulic servo press brake bending machine and the introduction of related information”.
Electro-hydraulic servo press brake bending machine can be controlled intelligently
Electro-hydraulic servo hydraulic press brake is the current domestic hydraulic press brake. It can be intelligently controlled, fully automatic production, and combined with a manipulator can save manpower. The electro-hydraulic servo-hydraulic bending machine is a panel-mounted structure based on 4-axis control, which can be installed directly on the electric cabinet or in the suspension cabinet. With DELEM’s friendly user interface and TFT true color LCD display, the DA-53T has all the basic functions of bending machine control. Its unique “shortcut key” method provides fast and concise programming.
Y-axis angle programming, table deflection compensation function and pressure control are all provided as standard. The technology-based DA-53T provides a stable and reliable solution. All-steel welded structure, with vibration aging treatment to eliminate internal stress, with good rigidity and stability; the flow rate from the servo proportional valve and the signal feedback from the electronic scale are combined to control the synchronous operation of the sliders (Y1, Y2).
The repeatability of the bottom dead center of the slider is 0.01mm, and the bending angle is 0.5°. The frame adopts an all-steel integral welded structure, and the internal stress is eliminated through normalizing and high-frequency vibration to ensure the overall accuracy of the machine tool, some rigidity, and excellent anti-distortion and anti-tilt capabilities. Thickened worktable plate and thickened slide block make the whole machine have high rigidity, so the deformation of slide block and worktable is extremely small when bending.
The workpiece has excellent straightness and angular consistency. The electro-hydraulic servo hydraulic bending machine adopts a double-cylinder structure. The electro-hydraulic proportional servo valve is synchronized (Y1, Y2). The electro-hydraulic proportional servo system is a position control system. The machine tool has strong anti-eccentric load capacity. It can dynamically detect the position error of the slider through the grating, and the electro-hydraulic proportional The valve controls and changes the movement speed of the two oil cylinders respectively, and then corrects the synchronization error of the slider. When one oil cylinder is fully loaded and the other oil cylinder is zero load (that is, the slider is fully eccentric), the slider can always The table remains parallel.
About electro-hydraulic servo press brake bending machine
When the electro-hydraulic synchronous bending machine is more and more widely used in the industry, more attention is paid to its power system. Suddenly, it is found that the current power system has changed a lot. Most of the press brakes use a servo-hydraulic hybrid system.
In the traditional electro-hydraulic synchronous bending machine, its power system generally uses a squirrel-cage induction asynchronous motor to control the oil pump to achieve the purpose of operation. Such a mode not only has a slow response speed, which affects production efficiency, but also requires a squirrel-cage induction asynchronous motor to clean the hydraulic system, and has the disadvantages of high noise and high maintenance costs.
Not only that, in the traditional power system of the electro-hydraulic synchronous bending machine, the oil pump body must be maintained at a certain speed to ensure the normal operation of the system. When the whole machine works in different working states, the speed requirements of the oil pump are different. The requirements for the oil delivery volume of the oil pump are also different.
All in all, this kind of power system cannot adjust the speed of the oil pump in time according to the working state of the whole electro-hydraulic synchronous bending machine, resulting in a waste of energy and making the motor easy to burn out. However, since the replacement of the servo-hydraulic hybrid system, various problems have been effectively solved, so that the electro-hydraulic synchronous bending machine can work normally.
This kind of power mainly uses the coding circuit, which is used to convert the working state command of the numerical control control circuit into an input signal that the servo drive circuit can recognize, and then realize the numerical control control under different working states of the electro-hydraulic synchronous bending machine. The circuit gives different working state instructions.
In addition, through the cooperation of the coding circuit and the servo drive circuit, the servo motor drives the oil pump at different speeds respectively, and cooperates with the action of the synchronous valve to realize the power supply of the whole machine of the electro-hydraulic and bending machine on demand, thereby reducing unnecessary waste. .
