How To Make A Cross Break In Sheet Metal

Coining one of the three types of bending for sheet metal where the punch penetrates into the sheet metal under high tonnage forming a consistent bend.

How to make a cross break in sheet metal.

Only a few degrees of bending angle are needed because the cross break pattern allows thin panels to stay relatively flat but still benefit from the increased rigidity that bending tensioning the sheet provides. The crossing ridges stiffen the face of the metal and help prevent is from buckling under a load. Box bending the process of bending a 4 sided sheet metal box. So we need to add the capability to reorder the flat pattern and add things after it that are not meant to be flattened.

This was done by two cross breaks. You add it to provide the information needed to create the cross break during manufacturing. Most common are doors. I believe that is what has been discussed as the preferred solution but the issue is that this cross break has to happen after the unfolding.

The cross break is not a geometric entity and does not alter the geometry of the part. How to bend sheet metal without a brake. They are typically used on relatively large flat ares to keep the panel from bowing easily. The functionality seems to be there in the solidworks cross break command on the sheet metal toolbar but upon inspection the cross break it inserts is merely cosmetic.

A question we sometimes get in the solidworks sheet metal course is how to insert a 3d cross break. Cross break light bends added to sheet metal in order to stiffen its surface. The cross break command lets you insert a graphical representation of a cross break in a sheet metal part. A cross break is simply a diagonal bend very slight bend from two corners of a part.

Cross breaks are most commonly in an x shape forming a slight pyramid shape in the metal without overly distorting it. A cross break in sheet metal is when multiple obtuse bend angles of approximately 170 are made across a flat section thin metal. To form lightweight parts that must avoid flexing cross break bending uses standard bending tools to make an x shaped pair of very shallow bends across the middle of the panel.
