Bend Line In Sheet Metal

You can add bend lines to a flat face of a sheet metal part with a sketched bend feature.

Bend line in sheet metal.

Next put your wooden or metal form blocks in the vice and clamp your sheet of metal between the forms. Manufacturing knowledge menu sheet metal knowledge sheet metal manufacturing and services. Consider a sheet with a 20 mm thickness and a length of 300 mm as shown in figure 1. In the featuremanager design tree expand drawing view to show the flat pattern feature.

Cells on the right will output the desired values. Parent topicdrawings of sheet metal parts. This page also includes a link to a on line calculator. 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.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. Here we will learn how to use sketched bend command in solidworks sheet metal and create a bend at any part of plan surface at any angle and dimension. To bend sheet metal in a vice start by marking a line on the metal where you want to bend it. You can add more than one line per sketch.

Some items to note about a sketched bend feature. Use the known k factor and the known inner bending radius to calculate the bending radius of the neutral line. Most sheet metal materials will conform to the calculations. Sketch on sheet metal face.

The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal. This lets you dimension the bend line to other geometry. 60 90 and 120 and we will calculate k factor bend allowance and bend deduction for them. We are going to review three bending scenarios with three different bending angles.

Only lines are allowed in the sketch. 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. 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. 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.
