Manhart How to ensure the machining accuracy of a downward moving CNC bending machine?

The key to ensuring machining accuracy of a CNC bending machine lies in its structural design, operating procedures, and the professional level of the operators and maintenance personnel. Here are some key points to ensure the machining accuracy of the downward moving CNC bending machine:
1. * * Structural Design * *:
-Rigid design: The body and worktable of the bending machine are made of high-strength steel, and the rigidity of the entire machine is ensured through reasonable layout and stable connection methods. This can effectively avoid vibration and deformation of the machine body and worktable during the machining process, ensuring machining accuracy.
-Load bearing design: The bending machine adopts a reasonable load bearing design to ensure that the worktable can withstand the weight of the metal sheet and maintain stability during the processing. Reasonable load-bearing design can prevent the workbench from sinking or deforming, which can affect machining accuracy.
-Precision guide rail: The slider and guide rail of the bending machine use high-precision linear guides to ensure the smoothness and accuracy of the slider during movement. The use of precision guide rails can reduce the frictional resistance of the slider and improve the accuracy of mechanical transmission.
-* * Precision Transmission * *: The transmission device of the bending machine adopts precision mechanical transmission methods such as gears and transmission belts to ensure transmission accuracy and efficiency. Precision transmission can reduce transmission errors and improve the accuracy and stability of bending machines.
2. * * Operating Procedure * *:
-* * Material Preparation * *: Prior to bending processing, necessary preparation work such as cutting, trimming, etc. should be carried out on the metal sheet. Reasonable material preparation can reduce machining errors and improve machining accuracy.
-Clamping and fixing: Clamp and fix the metal sheet to be processed on the workbench to ensure its position and angle stability. The rationality of clamping fixation will have a significant impact on the bending accuracy.
-* * Adjust parameters * *: Adjust the processing parameters of the bending machine reasonably according to the different processing requirements and workpiece materials, such as pressure, angle, speed, etc. Accurate parameter adjustment can improve machining accuracy.
-Processing process: During the processing, operators need to perform corresponding operations according to requirements, such as starting up, adjusting tool position, controlling processing speed, etc. The proficiency and operational skills of operators have a direct impact on machining accuracy.
-* * Quality Inspection * *: After processing, the workpiece is inspected for quality, including size, shape, angle, and other aspects. The qualified inspection results are an important standard to ensure the accuracy of the bending machine.
3. * * Professional level of technical maintenance and operation personnel * *:
-The maintenance and upkeep of CNC bending machines have a direct impact on machining accuracy. Regular inspection and maintenance of various components of the bending machine, timely detection and repair of possible faults and problems, can ensure the stability and accuracy of the machine tool.
-Operators need to have good CNC programming and operation skills, understand the working principle and performance of CNC bending machines, be able to correctly set processing parameters and adjust the machine tool, and judge whether the machining accuracy of workpieces meets the requirements.
4. * * Special Adjustment Techniques * *:
-Adjustment of slider stroke: Adjust the slider stroke distance based on the thickness of the folded plate and the size of the V-shaped opening in the lower mold to ensure machining accuracy.
-Adjustment of upper limit of slider: When the slider rises, the upper sleeve triggers the travel switch to keep the slider in the desired position, improving production efficiency.
-Slow motion adjustment of slider: When the slider descends, the travel switch is triggered by the lower limit block to make the slider move slowly, ensuring the stability of the machining process.
-Mold fine-tuning: Compensate for the deflection deformation of the slider and worktable, as well as the uneven wear of the mold during use, to improve bending accuracy.
In summary, the downward moving CNC bending machine can effectively ensure machining accuracy through precise structural design, optimized operating procedures, and professional maintenance and operation personnel.
