Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.
Bend relief in sheet metal.
You should also incorporate the use of bend relief cuts with a thickness of at least the thickness of the material with strong preference for bend relief cuts of a thickness.
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.
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.
Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on.
The diagram shows one such mechanism.
Click the create relief tool button on the sheet metal ribbon tab.
Enter relief size by bend radius ratio or force bend reliefs auto.
In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm.
Select a hard edge bend face flange face or 3d solid entire model.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
There are two things that can be done to reduce the risk of sheet metal tearing.
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.
Parent topic using sheet metal tools search corner reliefs and bend transitions in the solidworks knowledge base.
Choose create relief in the sheet metal menu.
Refer to the chart for values for folder as well as various press brake tooling combinations.
Select an item see the note below.
The gap between the bend and surrounding material allows us to shape the sheet in the press brake cleanly eliminating cracking and tearing.
One benefit of a bend relief is that it makes the part easier to produce.
Geometry of tooling imposes a minimum bend dimension.
If it is ok for the metal to rip the minimum bend relief is zero.
Bend relief and collars near pierced areas strengthen sheet metal parts.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
Avoid large sheet metal parts with small bent flanges.
First utilize minimal bend radius of internal bend radius equal to material thickness.
