Manhart What are the technical characteristics of electric servo bending machine?

The technical characteristics of electric servo bending machine mainly include the following aspects:
1. **High precision**:
– The main oil cylinders on both sides synchronously adopt German imported electro-hydraulic servo valves and German grating rulers to form closed-loop control, accurate response, and accurate slider operation.
– High bending accuracy and high slider repeat positioning accuracy can meet the processing needs of various complex parts.
2. **Powerful compensation function**:
– V-axis hydraulic compensation or mechanical compensation to solve the influence of slider deformation on workpiece quality during bending.
– The compensation amount is automatically adjusted by the CNC system, which is convenient and accurate.
3. **Full-function back gauge mechanism**:
– The functional components in the back gauge, such as guide rails, lead screws, bearings, etc., are imported to ensure the back gauge accuracy.
4. **Stable body structure**:
– The body adopts a split steel plate welding structure, which is tempered and vibrated to eliminate the deformation caused by welding stress and processing stress, and ensure the accuracy of the machine tool.
– Use ANSYS finite element analysis software to analyze important components such as the fuselage and slider to ensure the reliability of the machine tool.
5. **Efficient hydraulic system**:
– The hydraulic system adopts an integrated control system imported from Germany, which reduces pipeline installation, improves the working stability of the machine tool, and has a beautiful and simple appearance.
Regarding the setting of the back gauge of the CNC bending machine, you can refer to the following steps:
1. **Determine the retreat time**:
– According to the operator’s experience and specific conditions, it is usually set to about 1.5 to 2 times the bending time to ensure that the operator has enough time to make adjustments.
2. **Enter the setting menu**:
– On the control panel or operation interface of the bending machine, find the menu option for the back gauge retreat time setting.
3. **Enter the retreat time**:
– Enter the retreat time value in the menu and adjust it according to your needs and experience.
4. **Test and adjust**:
– Perform a test bend to observe the behavior of the back gauge and the operator’s work efficiency.
– Adjust the retreat time according to the actual situation. If necessary, make multiple adjustments until the ideal effect is achieved.
In addition, the adjustment of the back gauge also depends on the CNC system of the bending machine and whether it has a servo motor or frequency converter. Setting on the CNC system can achieve automatic adjustment, and on some advanced electro-hydraulic servo bending machines, the up and down and left and right of the back gauge can be adjusted by foot switches or other methods. For specific systems such as the CNC system of DA52, the required bending machine values ​​can be directly input on the system to adjust the back gauge position.
