pnneumatic axe robots

[Bodge Job]

We have been looking around, and so far have not found the parts to make it FP, but we Have already found al the parts for low presure, and were going for a rack and pinion style linkage, I was wondering about useing a 20mm (ish) nylon 6 body with a 5-10mm HDPE armour do you think this would be storong enough to sport the axe? Thanks

http://i1111.photobucket.com/albums/h46 ... B-orig.jpg my first CAD of the axe robot, although, the axe will be larger, and the dementions will be adjusted to fit the pneumatic

looks good, how are you doing your system?

i was thinking of going for something similar to how battle axe has it or shunt

At kiddeminster Jason turned up the pressure in thors axe a little to 11.5 bar as the rod was a bit bent and slowing the axe I think he usually has it about 10.5 bar.

looks nice alex, what CAD do you use?

[Bodge Job]

I used prodesk top, and I'm using a rack and pinion style system, I'm just trying to find a ram of the correct size ATM... And then I will adjust the cad, acordingly. and I used the engineering drawing, as it looks the clearest, and the CAD was multicolour, at the time, and I cba to change it...

i have to build around my ram, ive got a 40mm bore, 100mm stroke ram at 12 bar, should have some kick

[Bodge Job]

Yeh, I just can't find one, of the right detentions... I'm looking for about 50 mm bore, 150-180mm stroke... At about 10 bar, as that's quiet a universal presure...

i need to find a 12 bar reg, thats the hard bit since i believe that trev regs only run at 10 bar

[Bodge Job]

I would just run it at 10 bar if I was you, because it's still about 500 kgs of force coming from a 40mm bore ram... I'm only using the extra power, so I can flip robots using the specially shaped axe head....
