Rotary Bending Sheet Metal

Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the same.

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. One contact point acts as a holding pad while the opposite contact point rotates creating the bending action. 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 bend deduction is the amount the sheet metal will stretch when bent as measured from the outside edges of the bend. And a 3d shaping is possible. As the bender moves down the rocker makes contact with the sheet metal. 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. When sheet metal is bent it stretches in length. This method is the most commonly used freeform bending process to manufacture bending geometries consisting of several plane bending curves. After the bend is completed and on the press s returnstroke the spring forces the rocker to return back to its original or idle position figure 1.

And like their single rotary bending cousins these double rotary tools are designed to adjust for springback and angle variation from material inconsistencies. In a process the profile is guided between bending roll and supporting rolls while being pushed through the tools. This is done through the application of force on a workpiece. A press brake is used to give the final shape to a part.

It is important to bear in mind that bending is done after the cutting process. Bending large or heavy sheets especially to 90 degrees often requires excess labor and can cause safety concerns. With rotary bend tooling you get a smooth cost effective solution that uses up to 50 percent less tonnage. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

The cylinder is seated into a saddle making up the punch section of the die.
