Machine building: Roller V Dies

Freshly machined and ready to use, my roller bottom dies for my press brake.

Freshly machined and ready to use, my roller bottom dies for my press brake.

I have seen the Rolla-V dies for press brakes before, really want a set and am saving my cash for some. In the mean time I spent some after hours minutes machining and welding a set for myself. Just using a standard V-punch for right now but in the near future I will build a few radiused punches.

 

These things are pretty trick, if you search YouTUBE you will find a few other videos on how they work. My biggest reason for doing this is to be able to bend with a larger radius with accuracy for brake pedal arms or any other large material

    I see that you made a roller v die, I have parts 3″ wide x 1/2″ thick steel that have a slot near the bend line. I would like to make the roller v for my application to save money over buying, would you share any info on making yours?

    Thanks

    • There are a few YouTUBE videos on the use of these style dies. Searching for them and watching how they work might help you a bit. My dies max out on 3/8 plate, the fulcrums would have to be designed differently to do 1/2″ plate. And depending on how close the hole is to the bend line, that may make it just about impossible to get a good bend. Probably something that would need the hole put in after the bend was made.
