Sheet Metal Bend Line

Only lines are allowed in the sketch.

Sheet metal bend line.

Next put your wooden or metal form blocks in the vice and clamp your sheet of metal between the forms. To bend sheet metal in a vice start by marking a line on the metal where you want to bend it. Bend line the line across the metal where the punch comes in contact with the metal and the bend begins. You only have to insert interior angle flange lengths k factor inside radius and material thickness.

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. 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. You can add bend lines to a flat face of a sheet metal part with a sketched bend feature. Most sheet metal materials will conform to the calculations.

Some items to note about a sketched bend feature. Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. This lets you dimension the bend line to other geometry. The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal.

Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations. 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. This is done through the application of force on a workpiece. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses.

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. This page also includes a link to a on line calculator. 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. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

Bending the process of cold working metal to achieve a desired profile. Cells on the right will output the desired values.
