One benefit of a bend relief is that it makes the part easier to produce.
Bend relief in sheet metal.
Select an item see the note below.
If it is ok for the metal to rip the minimum bend relief is zero.
Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.
Avoid large sheet metal parts with small bent flanges.
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.
Enter relief size by bend radius ratio or force bend reliefs auto.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on.
There are two things that can be done to reduce the risk of sheet metal tearing.
First utilize minimal bend radius of internal bend radius equal to material thickness.
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.
The diagram shows one such mechanism.
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.
Type smreliefcreate in the command bar.
Design for manufacturability sheet metal guidelines bends for the ease of manufacturing multiple bends on the same plane should occur in the same direction.
Parent topic using sheet metal tools search corner reliefs and bend transitions in the solidworks knowledge base.
Bend relief and collars near pierced areas strengthen sheet metal parts.
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.
In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm.
Click the create relief tool button on the sheet metal ribbon tab.
Geometry of tooling imposes a minimum bend dimension.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
Use the corner relief propertymanager to apply corner treatments to a folded sheet metal body that persist in the flattened state.
Select a hard edge bend face flange face or 3d solid entire model.
Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
Choose create relief in the sheet metal menu.
