Bend Line Sheet Metal

Bend line the line across the metal where the punch comes in contact with the metal and the bend begins.

Bend line sheet metal.

This is done through the application of force on a workpiece. You can add bend lines to a flat face of a sheet metal part with a sketched bend feature. Cells on the right will output the desired values. This lets you dimension the bend line to other geometry.

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. How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools. You only have to insert interior angle flange lengths k factor inside radius and material thickness.

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. Mark your bend lines. Most sheet metal materials will conform to the calculations. 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.

Commonly used equipment include box and pan brakes brake presses and other specialized machine presses. How to bend sheet metal without a brake. Bending is one of the most common sheet metal fabrication operations. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius.

This page also includes a link to a on line calculator. Only lines are allowed in the sketch. 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. 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.
