Manhart How to improve the accuracy of the hydraulic servo CNC bending machine?

To improve the accuracy of the hydraulic servo CNC bending machine, detailed adjustments and optimizations can be made from the following aspects:
I. Regularly check and calibrate key components
1. **Check the deflection of the compensation cylinder**: Ensure that the deflection of the compensation cylinder is not too large and cannot be completely zeroed. Once the deflection is too large, it should be adjusted or replaced immediately to reduce its impact on the bending accuracy.
2. **Calibrate the grating ruler**: The looseness or error of the grating ruler will affect the positioning accuracy. Regularly check and calibrate the grating ruler to ensure its accuracy.
3. **Check the proportional valve**: The zero offset value of the proportional valve should be a suitable value to avoid affecting the accuracy due to hysteresis during positioning.
II. Optimize molds and tools
1. **Mold selection and accuracy**: Select high-precision upper and lower molds, and regularly check and replace molds to prevent the reduction of bending accuracy due to mold wear or deformation.
2. **Tool device stability**: Ensure that the tool device is stable to avoid errors in bending force or angle caused by tool instability during processing.
3. Adjust and set parameters
1. **Material parameters**: According to the physical properties and mechanical properties of the material (such as elastic modulus, tensile strength, etc.), reasonably set the machine parameters to improve the bending accuracy.
2. **Angle and radius**: According to the processing requirements, accurately set the bending angle and radius to ensure the same accuracy of each processing.
3. **Machine running speed**: Under the premise of ensuring accuracy, appropriately adjust the machine running speed to improve production efficiency.
4. Enhance operation and maintenance skills
1. **Train operators**: Improve the skill level of operators so that they can master the operation skills and maintenance requirements of the bending machine to avoid the decrease in accuracy due to improper operation.
2. **Regular maintenance**: Regularly clean, lubricate and check the fasteners of the bending machine to ensure stable operation of the equipment and improve processing accuracy.
5. Introduce advanced technology and equipment
1. **Apply high-precision CNC bending machine**: Select a CNC bending machine with a high-precision control system to improve processing accuracy and efficiency.
2. **Use data analysis tools**: Analyze the processing data, find problems in time and make adjustments to ensure processing accuracy.
VI. Other aspects
1. **Pay attention to the hydraulic system**: Ensure that the hydraulic system works properly to avoid the decrease in bending accuracy caused by hydraulic system problems.
2. **Keep the computer system updated**: Update the computer system regularly to ensure its stable operation and avoid the decrease in processing accuracy caused by system problems.
Through the comprehensive application of the above steps, the accuracy of the oil-electric servo CNC bending machine can be effectively improved to meet higher production needs.
