Can anyone tell me anything about bending tube ?
Can anyone tell me anything about bending tube ?
(OP)
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.

For rectangular tube, you can:
- Control the buckle location with external support, and allow it to happen.
- Bend it over a punch so you control the shape of the buckle.
- Support the inside while bending.
- Stretch the entire tube while bending- some inside support may still be required.
- Support the outside and pressurize the inside while bending.
Go to some new car and truck dealers and crawl around under the vehicles, looking up. You will find a lot of bent tubes, many with intentional wrinkles.

What sort of radius are we talking, and is this one bend or thousands. If we're talking thousands, how about a mandrel system.

You might contract hydroformer to assist you in selecting a hydroforming machine to buy, or in designing one if you insist on homebrewing.
