Bend Line Sheet Metal

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.

Bend line sheet metal.

This page also includes a link to a on line calculator. Some items to note about a sketched bend feature. A cutout or the edge of your flange to your bend. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

Choose a bend radius that matches your minimum bend. 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. The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal.

This is done through the application of force on a workpiece. Most sheet metal materials will conform to the calculations. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius. 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.

Bending is one of the most common sheet metal fabrication operations. This lets you dimension the bend line to other geometry. Only lines are allowed in the sketch. Recommended inside bend radius for sheet metal parts should be equal to material thickness.

Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. Cells on the right will output the desired values. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Determine your minimum bend by measuring the distance from your closest feature i e.

If you have any questions or want to discuss your design contact us. 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. 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. But for harder materials e g.

Commonly used equipment include box and pan brakes brake presses and other specialized machine presses.
