Does anyone know anything about bending steel tube ?

[Jamaz17]

Hey,

I am designing a machine to bend a rectangle tube with .125 wall 1 1/2 x 3 mild stell. The bend I have to make is 5 degrees with the bend on the long face. Can anyone think of any problems I might have doing this, or which method of bending might be more suitable? I have done a few test bends using a simple press and no mandrel and the tube in caving in on the inside of the radius. Does anyone have any ideas or has anyone built a bender before. Thanks for the help as benders are new to me.

Thanks, James

there are a number of commercial bender and die sets available to bend almost any shape. The magic is in the dies. Google a couple manufacturers, buy the dies and build your machine around it.

There are so many benders available I find it hard to believe you need to design one.
