Tube Bead Roller

[Astro]

My latest tool project is a bead roller for forming a bead on the end of a tube. I need to use this tool to make new engine coolant tubes for my racecar. It could also be used to make intake tubing for turbo applications.
I saw the design concept on the net, and made my own version.




This is a small test piece to show the results.

I love the neat and compact design, no gears exposed whatsoever.

Hi Altair, the dies are not connected in any way, the process relies on friction on the inside of the tube to turn the tube. I have not yet experienced any negative issue with this arrangement but if I do I may bead blast the internal die for more grip.

I like simple machines like this one. Looks great, and I just may have to steal your idea.

Beautiful work!

Can you clarify "not connected"?
Is the only driven element the bottom die?
If you have any pictures of the top die, that would be helpful.

Great project! Thanks.

Hi Nitrous, thanks for checking out my tube beader. You are correct in that the only driven element is the bottom die.
I have taken some pictures of the upper die and other detail.

this is the backside of the die with spacer ring

this is the front side of the die, 6203 bearing

profile of the die

rear of die axle detail

front of die axle detail only the outer circlip groove is used, the inner one was a mistake.
