Bend Line Sheet Metal

With this free online tool we quickly get the sheet metal bend deduction and therefore the sheet metal blank initial flat length from the finished part measurements.

Bend line sheet metal. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. Bump bending also known as step bending the process for forming a large radius with conventional tooling by performing a series bends in close proximity. This is done through the application of force on a workpiece. Now that you know your bend allowance take your protractor and draw a clear line with your marker across the point at which you will bend your sheet metal.

This lets you dimension the bend line to other geometry. Bending is a manufacturing process that produces a v shape u shape or channel shape along a straight axis in ductile materials most commonly sheet metal. Bending is one of the most common sheet metal fabrication operations. Choose a bend radius that matches your minimum bend.

Only lines are allowed in the sketch. Mark your bend lines. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Most sheet metal materials will conform to the calculations.

The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal. Determine your minimum bend by measuring the distance from your closest feature i e. A cutout or the edge of your flange to your bend. But for harder materials e g.

You can add bend lines to a flat face of a sheet metal part with a sketched bend feature. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses. Some items to note about a sketched bend feature.

Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. This page also includes a link to a on line calculator. If you have any questions or want to discuss your design contact us. Cells on the right will output the desired values.

Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius.
