Bend Line Sheet Metal

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.

Bend line sheet metal.

Commonly used equipment include box and pan brakes brake presses and other specialized machine presses. 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. How to bend sheet metal without a brake.

This page also includes a link to a on line calculator. Most sheet metal materials will conform to the calculations. This lets you dimension the bend line to other geometry. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius.

Sheet metal manufacturing and services the following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal. Bending is one of the most common sheet metal fabrication operations. Only lines are allowed in the sketch. Cells on the right will output the desired values.

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 the line across the metal where the punch comes in contact with the metal and the bend begins. Mark your bend lines. You can add bend lines to a flat face of a sheet metal part with a sketched bend feature.

Some items to note about a sketched bend feature. You only have to insert interior angle flange lengths k factor inside radius and material thickness. To think about bending a sheet of metal that has appreciable thickness focus on an imaginary central sheet the so called neutral line or neutral axis within the 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.
