Bending parts are a common type of Metal Stamping parts, but regarding how to confirm the bending sequence for products with multiple bends, today we will explain the bending sequence for metal stamping parts with continuous bending.

General bending sequence:

1. Short side first, long side later: Generally speaking, when all four sides are bent, folding the short side first and then the long side is beneficial for the processing of metal stamping parts and the assembly of bending molds.

2. First the periphery and then the center: Normally, it is bent from the periphery of the stamped part towards the center of the workpiece.

3. Part first, then whole: If there are some structures inside or outside the stamped part that are different from other bends, it is generally necessary to bend these structures first and then bend other parts.

4. Consider the situation and arrange the bending sequence reasonably: The bending sequence is not fixed, and the processing sequence should be adjusted appropriately according to the shape of the bending or obstacles on the stamped part. After designing the bending sequence according to these four principles for the continuous bending of metal stamping parts, please check if the following requirements can be met:

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

2. Check if the lower blade or fixture of the bending machine blocks the position for the next bending.

3. Check if the previous bending has scraped or bumped against the bending tool and fixture after this bending.

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

5. See if the size of the previous bend can be used as the positioning reference for the next bend.
