Rotary Bending Sheet Metal

The formed bend radius is dependent upon the dies used the material properties and the material thickness.

Rotary bending sheet metal. Nanjing byf o machinery co ltd whatsapp. Bending of sheet metal is a common and vital process in manufacturing industry. 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.

The bend radius refers to the inside radius. Not to mention sheets get marked up in the bending process. As the bender moves down the rocker makes contact with the sheet metal. 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.

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. Sheet metal folding is a very common forming method used to give the desired shape to structural steel stainless steel aluminium etc. In a process the profile is guided between bending roll and supporting rolls while being pushed through the tools. 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. Therefore you have to keep some design tips in mind. This is done through the application of force on a workpiece. 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. 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. With rotary bend tooling you get a smooth cost effective solution that uses up to 50 percent less tonnage.

This method is the most commonly used freeform bending process to manufacture bending geometries consisting of several plane bending curves. When sheet metal is bent it stretches in length. A press brake is used to give the final shape to a part. The cylinder is seated into a saddle making up the punch section of the die.

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