Bend Line Sheet Metal

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.

Bend line sheet metal.

Recommended inside bend radius for sheet metal parts should be equal to material thickness. 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. But for harder materials e g.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. This lets you dimension the bend line to other geometry. Bending is one of the most common sheet metal fabrication operations. Cells on the right will output the desired values.

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. 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. Most sheet metal materials will conform to the calculations. If you have any questions or want to discuss your design contact us.

Some items to note about a sketched bend feature. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. 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. Mark your bend lines.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. Bend line the line across the metal where the punch comes in contact with the metal and the bend begins. A cutout or the edge of your flange to your bend. Determine your minimum bend by measuring the distance from your closest feature i e.

Commonly used equipment include box and pan brakes brake presses and other specialized machine presses. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. Only lines are allowed in the sketch. Choose a bend radius that matches your minimum 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.
