Yes. What's going on to the right is a steady-rest (when needed) and an a live center at the very tip. I've done this before with a manual/mechanical set-up using a rotary cam plate and a long hand lever and it worked. This is just bigger, longer and meaner requiring more force. Thicker wall...
Thanks, btrueblood. In this case the "plenum" would be the shop's common air compressor tank which delivers about 120 psi going into two 4" pneumatic cylinders should yield something over 1500 lbs force each....all things being equal, which seems to be the question. Unless advised otherwise...
OK Here's an update. I hope I still have everyone's attention. I've redesigned the setup using only two air cylinders which will be installed “nose to nose” opposing, with metal forming going on in between using rollers while it spins. To be clear, the idea is to spin-form an aluminum tube over...
I have been redirected to peruse electric linear actuators for this application which is metal forming, in case I didn't mention it. The situation will require a good amount of static force over a period of time but at least they can be coordinated more easily by electronic controller...
Fair enough and thanks again for your support, gerhardl. I will report back. I got my "working papers" today. Very official looking stuff. Seems I'm an essential manufacturing worker in keeping with the Emergency Act having to do with national defense. You'd think that they would at least...
Thank you gerhardl and LittleInch. That was was helpful. I didn't realize anyone had answered. I'm still learning to navigate the ETF board. I think what I must do after reading your replies is consult with a vendor's technical advisor, tell them what I want to do and have them set me up with a...
I've been tasked with designing a system using three air cylinders working together simultaneously. They will be 4" double action cylinders, 1" rods with 2" travel arranged 120 deg apart arriving at a center (circular) focus at the same time and applying the same force and then return. I'm...
