During the bending process, following a specific sequence is crucial. First, ensure that the sheet metal part is properly prepared before bending, including cleaning, positioning, and securing. Second, develop a reasonable bending sequence based on the shape and size of the sheet metal part to ensure stability and accuracy during processing. Finally, perform necessary inspections and adjustments after bending to ensure that the product quality meets the requirements.
Follow an inside-out bending sequence, bending the internal structures first and then gradually expanding outwards.
Perform bending in order from smallest to largest dimensions to ensure accuracy at each step.
Prioritize bending of special shapes before regular shapes to improve work efficiency.
Ensure that the completion of one process does not affect or interfere with subsequent processes, thus maintaining a smooth overall processing flow.
In addition, attention should be paid to the selection of the bending radius during the bending process. An excessively large or small bending radius can affect product quality: A radius that is too small may cause cracking at the bend, while a radius that is too large may cause springback, affecting accuracy. Furthermore, for workpieces requiring secondary or multiple bends, special attention should be paid to avoiding interference between the workpiece and the tooling.
