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.
Sheet metal bend line.
To bend sheet metal in a vice start by marking a line on the metal where you want to bend it.
This page also includes a link to a on line calculator.
The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal.
The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length.
Commonly used equipment include box and pan brakes brake presses and other specialized machine presses.
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.
This is done through the application of force on a workpiece.
The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.
Therefore the bend allowance added to the flange lengths is equal to the total flat length.
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.
You can add bend lines to a flat face of a sheet metal part with 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.
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.
Cells on the right will output the desired values.
Some items to note about a sketched bend feature.
Bending the process of cold working metal to achieve a desired profile.
This lets you dimension the bend line to other geometry.
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.
If your sheet metal is long ask a friend to stabilize the part hanging out from the form blocks so it doesn t affect the bend.
Next put your wooden or metal form blocks in the vice and clamp your sheet of metal between the forms.
Only lines are allowed in the sketch.
