Bend Line Sheet Metal

Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material.

Bend line sheet metal.

Bending is one of the most common sheet metal fabrication operations. Bend line the line across the metal where the punch comes in contact with the metal and the bend begins. But for harder materials e g. A cutout or the edge of your flange to your bend.

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. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Recommended inside bend radius for sheet metal parts should be equal to material thickness. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius.

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. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. This lets you dimension the bend line to other geometry. Some items to note about a sketched bend feature.

If you have any questions or want to discuss your design contact us. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses. The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal. Choose a bend radius that matches your minimum bend.

Cells on the right will output the desired values. 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. 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. Only lines are allowed in the sketch.

Most sheet metal materials will conform to the calculations. 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. 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.

Determine your minimum bend by measuring the distance from your closest feature i e.
