Sheet Metal Bend Line

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.

Sheet metal bend line.

Cells on the right will output the desired values. Some items to note about a sketched bend feature. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. This is done through the application of force on a workpiece.

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. Therefore the bend allowance added to the flange lengths is equal to the total flat length. The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal.

Only lines are allowed in the sketch. This lets you dimension the bend line to other geometry. Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. This page also includes a link to a on line calculator.

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. 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. Bending the process of cold working metal to achieve a desired profile. Next put your wooden or metal form blocks in the vice and clamp your sheet of metal between the forms.

Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. You can add bend lines to a flat face of a sheet metal part with a sketched bend feature. Bend line the line across the metal where the punch comes in contact with the metal and the bend begins.

Your bend lines are stored in the same location as above but there are 2 other sheet metal features that can interfere if you change the default way those are displayed if you do not change anything with in them then you should have nothing to worry about. Most sheet metal materials will conform to the calculations.
