Posted: Tue Jun 12, 2012 10:05 pm Post subject: Tube bender build
|
|
|
Not too sure if this belongs here...feel free to move it if you like mods,
Thought i'd share the build of my new tube bender,(may be of interest to some) didn't fancy doing the new truck build with a centrepress bender, if not purely because its hard work! plus hopefully can make some ££ on the side doing bits and bobs, will be buying Bend-tech soon so can design stuff on laptop and acurately bring them to life, seems to get some really good reviews!
so anyway, i cheated and ended up buying the bender arms, had the drawings to get them machined myself but by the time i had bought/made pins and bought a degree ring the price probably wouldn't have been much different! Matt at stakesys did a good price
looked around on the net//youtube etc, theres loads of people converting them to hydro in different styles, i prefer the horizontal ones as although it takes up more space its easier to handle a 7.5m length of tube horizontally and easier to visualise whats going on!
Hydraulic wise...most use 230v motors rigged to pumps which is great but they don't half make a racket, its not that big'a deal but i liked the idea of not having to keep turning it off between finishing a bend and setting up for the next. also with the setups that use a spool block you have to stand where the lever is while bending, i fancied being able to move around so i can get a better view of whats going on.
Soooo.....i bought the hydraulic setup from a lorry tail lift, ram was about the right size and DC pump means i can have it operated from a wander lead. it will also be 100% portable.
mocked it up roughly, then made a framework for it to all sit on

Ram didn’t have an eye at each end but managed to butcher the part from the tail lift that the ram slotted into a useable fitting to go onto bender arms
Then a couple months passed by, as when I tried to get it running initially although it powered out fine, I couldn’t get it to retract as the original hydraulic line/valves had flow restrictors in them to make the tail lift drop controllably, but in my application meant I couldn’t close it for s***!
That kind of ruined my motivation for it, coupled with a lack of funds and time it sat unfinished until this weekend when I got motivated! Went to local hydraulic supplier and bought a diverter valve, in one position the ram extends , in the other position it returns the fluid from the ram back to the tank through a newly fitted return line.
On with the frame:
Pretty much finished now, just need to get a 12v solenoid (motor and solenoid was 24v, motor runs fine just slower on 12, solenoid won’t operate! ) and need to sort return springs, was waiting to check it does return ok with the new hydraulic setup, which it does! and of course got to purchase a die set, need to save up!

Pretty sure JD2 are different, JMR takes same as Pro tools so will end up getting from stakesys. still weighing up between 6 and 7" radius. anyone got any input? both have their pro's and con's but can't justify both at the minute.
being able to bend slightly thinner tube with the 7" doesn't really make much difference to me

I can't help you with your decision but I would like to see your list of pros and cons regarding both sizes - or anyone else's for that matter

I'm trying to remember back a long time but I believe the standard radius of a tube is 3 times it's own diameter - would have to get my machinery handbook out to check on that though

Nice work aniesigh
I just ordered 1.66 in 5.5 CLR and 1.9 in 6.5 CLR,250£ and 297£
I wanted as tight as possible and advised that that was it!!
Personally i think wider bends dont look great.
Will be doing a simular job to yours on the JD soon

Mtm have you used the bender yet as most bottle type jacks will not work when laid flat like in the pic

Depends where the oil pickup point is - all my bottle jacks will work on their side providing the pump is on the bottom

doing a little work on my bender aniesigh and found that if i mount the ram as close as that to the fixxed arm the rod wont clear a 6.5 CLR at full stroke,my ram may be longer than yours but something to be thinking about,you can always repin but nice to use all stroke

yes all works fine i did have to blead the jack but as it was new i had to do it any way. i was going to go full hydro as they will work faster but this way worked out cheaper for me
i did make an alteration to the ram fixing so it will disconect from the bender arm then it will swing back when not in use

I can nearly get full stroke out of my ram but not quite, actually using a different ram now, gone to double acting which i was trying to avoid doing all along as was trying to keep costs down and the S/A ram came with my pump, but its a much better setup in the end. looking forward to actually using it soon!

MTM, where did you get your digital read out from? looks
a more up to date pic of mine:
now double acting, but still got the push button to turn pump on so set direction then press button for go, means i can still move around to support tube/check all is well while bending and not restricted to standing next to the valve.
Got a nice new tube notcher too:
and bend-tech learning is coming along well
