Bend Line In Sheet Metal

Hiding the bend lines also hides the sheet metal bend notes.

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. Parent topicdrawings of sheet metal parts. This page also includes a link to a on line calculator. 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. The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal. Expand the flat pattern feature right click bend lines and select show or hide. Sketch on sheet metal face.

Cells on the right will output the desired values. 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. Most sheet metal materials will conform to the calculations. Manufacturing knowledge menu sheet metal knowledge sheet metal manufacturing and services.

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. 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. 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.

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. To bend sheet metal in a vice start by marking a line on the metal where you want to bend it. 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. Consider a sheet with a 20 mm thickness and a length of 300 mm as shown in figure 1.

This lets you dimension the bend line to other geometry. Only lines are allowed in the sketch. You only have to insert interior angle flange lengths k factor inside radius and material thickness. 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.
