Bend Line In Sheet Metal

60 90 and 120 and we will calculate k factor bend allowance and bend deduction for them.

Bend line in sheet metal.

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. 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. Sketch on sheet metal face. The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal.

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. 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. 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. Hiding the bend lines also hides the sheet metal bend notes. 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. Most sheet metal materials will conform to the calculations. Cells on the right will output the desired values. We are going to review three bending scenarios with three different bending angles.

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. You can add more than one line per sketch. You only have to insert interior angle flange lengths k factor inside radius and material thickness.

You can add bend lines to a flat face of a sheet metal part with a sketched bend feature. Some items to note about a sketched bend feature. Parent topicdrawings of sheet metal parts. 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.
