Bend Line In Sheet Metal

To define the bend region and reduce the force required to bend a part out of sheet metal down to something you can handle without a brake press slots can be cut at the bending line to.

Bend line in sheet metal.

Some items to note about a sketched bend feature. A customer had recently called in looking for a way to show his bend lines on the drawing of his sheet metal parts and while some people may say the answer is simple there are several ways to get the bend lines to show or not show in your drawing. Expand the flat pattern feature right click bend lines and select show or hide. Use the known k factor and the known inner bending radius to calculate the bending radius of the neutral line.

In sheet metal design the k factor is used to calculate how much sheet metal one needs to leave for the bend in order to achieve particular final dimensions especially for between the straight sides next the bend. To bend sheet metal in a vice start by marking a line on the metal where you want to bend it. Sketch on sheet metal face. Next put your wooden or metal form blocks in the vice and clamp your sheet of metal between the forms.

Parent topicdrawings of sheet metal parts. 60 90 and 120 and we will calculate k factor bend allowance and bend deduction for them. The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal. 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.

This page also includes a link to a on line calculator. This lets you dimension the bend line to other geometry. Consider a sheet with a 20 mm thickness and a length of 300 mm as shown in figure 1. Most sheet metal materials will conform to the calculations.

We are going to review three bending scenarios with three different bending angles. Manufacturing knowledge menu sheet metal knowledge sheet metal manufacturing and services. Cells on the right will output the desired values. In the featuremanager design tree expand drawing view to show the flat pattern feature.

You can add bend lines to a flat face of a sheet metal part with a sketched bend feature. 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. Hiding the bend lines also hides the sheet metal bend notes. You can add more than one line per sketch.
