Bending parts are a common product in hardware stamping manufacturers, but for products with multiple bends, how to determine the bending sequence? Today, we will explain the bending sequence of 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 stamped parts and the assembly of bending molds.

2. First the periphery and then the center: Under normal circumstances, it is generally bent from the periphery of the stamped part towards the center of the workpiece.

3. Partial first and then overall: 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 criteria, the hardware stamping parts manufacturer should check whether they can meet the following requirements:

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 there were any scratches or collisions with the bending tools and fixtures after the last bending.

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

5. See if the scale of the last bend can be used as the positioning reference for the next bend.
