In metal bending equipment, electro-hydraulic servo CNC metal sheet bending machine not only has higher accuracy, but also allows workers to operate more efficiently. In addition, the V-groove opening of the lower die of the electro-hydraulic servo sheet metal bending machine will be customized according to the thickness of the workpiece. In most cases, the V-groove opening needs to be much larger than eight times the thickness of the folded workpiece. Different upper and lower dies can be used to fold a variety of workpieces, and the formation of a workpiece requires multiple bending steps to complete.
The electro-hydraulic servo sheet metal bending machines currently on the market are mostly made of steel. In order to ensure that the sheet metal bending machine can run smoothly and efficiently, the processing methods used to manufacture different parts of the machine tool steel are also different. The electro-hydraulic servo sheet metal bending machine adopts a hydraulic transmission method to avoid overload operation accidents caused by changes in sheet thickness. Compared with ordinary sheet metal bending machines, this machine tool has more stable operation, more convenient operation and higher safety factor. Its upper die will use compensation technology to compensate for the deflection deviation of the worktable and ensure the high precision of the workpiece.
The electro-hydraulic servo sheet metal bending machine adopts electro-hydraulic control, adjustable slider stroke, and advanced technology. It is an ideal bending equipment.

The main oil cylinders on both sides adopt German imported electro-hydraulic servo valve and German HEIDENHAIN grating ruler to form a closed-loop control. The feedback is accurate and the slider runs accurately, so that the bending accuracy and the repeatable positioning accuracy of the slider are high.
● Integral welding processing structure
● Imported internationally renowned flat brand electro-hydraulic servo valve and grating ruler form a closed-loop control mode

● Backgauge can adopt a more complete backgauge mechanism with multiple backgauge shafts according to customer needs.
● The hydraulic system adopts an integrated control system, which reduces pipeline installation and customer service oil leakage, and ensures the working stability of the machine tool with a scientific and beautiful appearance.
● The hydraulic deflection automatic compensation mechanism eliminates the influence of the deformation of the slider on the quality of the workpiece. The numerical control system automatically adjusts the compensation amount, which is convenient and accurate.
● The numerical control system adopts special numerical control systems for sheet metal bending machines of well-known brands such as DELEM in the Netherlands, ESA in Italy, and CYBELEC in Switzerland.
How does the CNC sheet metal bending machine work and what is the principle?
The CNC sheet metal bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a working table and a clamping plate. The working table is placed on the bracket. The working table is composed of a base and a pressing plate. The clamping plates are connected, and the base is composed of a seat shell, a coil and a cover plate. The coil is placed in a recess of the seat shell, and the top of the recess is covered with a cover plate. In the technical field of CNC sheet metal bending machine, the research and application of real-time intelligent control are developing along: adaptive control, trance control, neural network control, expert control, learning control, feedforward control, etc. Because the CNC sheet metal sheet bending machine adopts electromagnetic force clamping, the pressing plate can be made into a variety of workpiece requirements, and the workpiece with sidewalls can be processed, and the operation is very simple.
The CNC sheet metal bending machine adopts a graphical user interface. The unified group control system can automatically adjust the information activity state according to different production processes and perform the functions of the group control system. The user interface is a dialogue interface between the CNC sheet metal bending machine system and the user. The graphical user interface should be suitable for various users including non-professional users. It can be manipulated through windows and lists. CNC sheet metal bending The bending machine can realize functions such as graphic simulation, graphic dynamic tracking, simulation and fast programming. Users can re-develop the system software of CNC sheet metal bending machine according to their own needs, and the user’s scope of use is no longer restricted by the manufacturer. The CNC sheet metal sheet bending machine system adopts a new generation of modular design, with wider functional cage cover and stronger reliability, which can meet the needs of different users.
Introduction to the working mode of CNC sheet metal bending machine:
(1) Set the pressure holding time, pressure relief time, and the distance of the horizontal stop, adjust the position of the horizontal stop of the CNC sheet metal bending machine.
(2) Set the number of steps of the CNC sheet metal sheet bending machine, as well as the stop position and the number of bending sheets for each step.
(3) Select the continuous operation gear position, the press sheet metal bending mechanism is not at the upper stroke switch position, first automatically return to the upper stroke switch position; step on the pedal to advance slowly, press the sheet metal bending mechanism to automatically press down; touch down the stroke When it is switched on and off, the horizontal stopper mechanism moves back to a set distance and automatically maintains pressure at the same time; the CNC sheet metal sheet bending machine automatically releases the pressure when the pressure is maintained, and automatically returns when the pressure relief time reaches the lower pressure sheet metal bending mechanism. The horizontal stopper mechanism automatically advances the set distance; when the travel switch is touched, one bending action ends, and the next bending is performed.
(4) When the current step of bending is completed, the stroke switch is touched, the horizontal stop position is automatically adjusted, and the CNC sheet metal sheet bending machine enters the next step of bending.
(5) When all the steps are completed and the stroke switch is touched, the continuous bending action of the CNC sheet metal sheet bending machine ends.
