Sheet Metal Bend Line

Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork.

Sheet metal bend line.

This page also includes a link to a on line calculator. 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. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. If your sheet metal is long ask a friend to stabilize the part hanging out from the form blocks so it doesn t affect the bend.

The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal. Therefore the bend allowance added to the flange lengths is equal to the total flat length. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. 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.

You can add bend lines to a flat face of a sheet metal part with a sketched bend feature. Only lines are allowed in the sketch. Bending the process of cold working metal to achieve a desired profile. Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations.

This lets you dimension the bend line to other geometry. 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 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. Some items to note about a sketched bend feature.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. You only have to insert interior angle flange lengths k factor inside radius and material thickness. To bend sheet metal in a vice start by marking a line on the metal where you want to bend it. Cells on the right will output the desired values.

Bend line the line across the metal where the punch comes in contact with the metal and the bend begins. This is done through the application of force on a workpiece.
