How to Determine the Continuous Bending Sequence of Metal Stamping Parts

Bending parts are a relatively common type in Metal Stamping parts, but how to determine the order of bending for products with multiple bends? Today, we will explain the bending order of metal stamping parts that are continuously bent.

Bending in general order:

1. First short side, then long side: Generally speaking, when all four sides are bent, the short side is folded first, and the long side is folded later, which is conducive to the processing of stamping parts and the assembly of bending dies.

2. First the periphery and then the middle: Under normal circumstances, it is usually bent from the periphery of the metal stamping part to the center of the workpiece.

3. First part and then whole: If there are some different bending structures inside or outside the stamped parts, these structures are usually bent first and then other parts are bent.

4. Consider the situation and arrange the bending sequence reasonably: the bending sequence is not static, and the processing sequence should be properly adjusted according to the shape of the bending or the obstacles on the stamping parts. After designing the bending sequence according to these four criteria, check whether it can meet the following requirements:

1. Consider whether the cutting tools of the bending machine meet the requirements of the drawings.

2. Check whether the lower knife or fixture of the bending machine blocks the next bending position.

3. Check whether the previous bending is scratched or bumped with the bending tool and fixture after this bending.

4. See if the final bend is scratched or bumped against the bending tool and fixture.

5. See if you can use the scale of the previous bend as the positioning reference for the next bend.
