The Purpose of Bend Dies in Rotary Draw Bending

Use of bend dies

Rotary draw bending is the most popular form of tube and pipe bending. Used in industries as diverse as aerospace and automotive, rotary draw bending can create precision bends in a repeatable process with the use of precision tooling and dies sets.

Choosing a Bend Die

The tube is bent around the bend die, so the die determines the radius of the bend. There are a variety of bend dies available, from the simple to the complex, and it can be difficult to know which dies to use.

Most often the type of bend will dictate the type of die that is appropriate. For instance, when the height is larger than the width you will most often use a pedestal and flange mount bend die. This type of rotary draw bending die incorporates a platform for added stability and may, or may not, have a tool post.

The first step in choosing a bend die will be determining the material you will be bending and the type of bend you will be performing. Together, these two pieces of information will inform your die choice.
