Rotary bending sheet metal.

The formed bend radius is dependent upon the dies used the material properties and the material thickness. Not to mention sheets get marked up in the bending process. Sheet metal folding is a very common forming method used to give the desired shape to structural steel stainless steel aluminium etc. Creating a change in the part s geometry.

And like their single rotary bending cousins these double rotary tools are designed to adjust for springback and angle variation from material inconsistencies. Bending large or heavy sheets especially to 90 degrees often requires excess labor and can cause safety concerns. A press brake is used to give the final shape to a part. Bending of sheet metal is a common and vital process in manufacturing industry.

As the bender moves down the rocker makes contact with the sheet metal. In a process the profile is guided between bending roll and supporting rolls while being pushed through the tools. A rotary die is a special type of punch die combination which bends the sheet metal using a rotating cylinder with a v opening cut into the side of the cylinder. Bending is one of the most common sheet metal fabrication operations.

The bend deduction is the amount the sheet metal will stretch when bent as measured from the outside edges of the bend. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the same. And a 3d shaping is possible. One contact point acts as a holding pad while the opposite contact point rotates creating the bending action.

The bend radius refers to the inside radius. With rotary bend tooling you get a smooth cost effective solution that uses up to 50 percent less tonnage. Therefore you have to keep some design tips in mind. Some specialized applications use double rotary bending systems that can help make two angles at once often to form deep channels in sheet metal.

The sheet metal lays on an anvil and the rotary die is pushed down on top of it. This method is the most commonly used freeform bending process to manufacture bending geometries consisting of several plane bending curves. This is done through the application of force on a workpiece. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

It is important to bear in mind that bending is done after the cutting process.
