Bend Relief Sheet Metal

Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.

Bend relief sheet metal. Lack of proper bend reliefs may cause tearing of the material due to localized stresses. Bend relief and collars near pierced areas strengthen sheet metal parts. Enter relief size by bend radius ratio or force bend reliefs auto. The flange which does not have relief will result in a greater amount of distortion or tearing of the adjacent material.

The diagram shows one such mechanism. Improper bending of sheet metal can cause material flow problems in soft material and fracturing in hard materials. Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. Refer to the chart for values for folder as well as various press brake tooling combinations.

Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on. You are also able to select to extend the bend relief in the opposite direction in the case of a flange for example illustrations below. Use the corner relief propertymanager to apply corner treatments to a folded sheet metal body that persist in the flattened state. In general a minimum bend relief is equal to the material thickness plus the inside bend radius.

Parent topic using sheet metal tools search corner reliefs and bend transitions in the solidworks knowledge base. Sheet metal bend relief modify a bend relief the small cut made where the bend end meets a free edge and by specifying a shape and either a depth and relief width scale or specific bend relief depth. For example if you make a partial flange as above using all the defaults the software makes relief cuts at the end of the bends as shown to the right. Select an item see the note below.

Click the create relief tool button on the sheet metal ribbon tab. A bend relief creates space between the bent and unbent surfaces so that the edge of the sheet metal is perpendicular to the bend itself. Geometry of tooling imposes a minimum bend dimension. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.

Choose create relief in the sheet metal menu. Type smreliefcreate in the command bar. This article looks at two different tips associated with ensuring you have high quality sheet metal in finished products. If it is ok for the metal to rip the minimum bend relief is zero.

One benefit of a bend relief is that it makes the part easier to produce.
