Need Rod bent and formed

On the tail end. I have done considerable work with Festo cylinders (and have a few if you haven't acquired yours yet) and built a few things that did need to be articulated. Look at heavy equipment for instance, on the hydraulics. Most all of the cylinders are mounted on the end to allow the body to follow either some linkage, or attachment point to a hinged object i.e. bucket on a hoe or blade on a dozer.
 
Thanks for the reply all. This will allow the reloading press to be pneumatically controlled as RJ mentioned. Parts #1 and #5 are the main two parts I am trying to bend.

In the completed diagram, Part #2 is Pneumatic cylinder, Part #3 is a threaded linage that attaches to part #2. These two off the shelf parts allow to attach the Pneumatic to the dog leg part #1. This allows there to be motion on both ends of part #1.

Part #5 is the other custom part that will attach to the reloading press's arm to allow for pneumatic control.

RJ: I'll be doing a FL Resize on 9mm and 223 brass..... do you think the force would be sufficient to complete?


I'm all for less chance of breakage and issues.

What I can investigate is using a straight line and roller that Tony & Silver bullet suggests.:
Using a 3/8 or 3/8 X 5/8 flat stock as the straight part.

SilverBullet: How would you connect the flat bar to the reloading press (part #5)

Thanks
I have an RCBS press and, as I recall, when doing a full length resize, I had to put all my weight into the lever arm. So figure 200+ lbs. at the end of a ft. long lever plus the mechanical advantage of the press at the end of the stroke and you're probably looking at several hundred foot lbs. of torque. I would set up the press with the OEM arm and try a resize to get an estimate of the force/torque required for your press.

SolidWorks has incredibly more use than just drawing parts. I would make a model of the existing press as accurately as possible. It requires some reverse engineering but that's a good exercise for a young and inquiring mind. Model each moving part separately and combine them into an assembly. Mate the parts so that they are constrained to move in a realistic fashion and measure the angle of rotation of the press arm. I would look at just using a straight arm for part #5 and connecting it directly to the cylinder at part #3. The opposite end of the cylinder can be a pivot point, as Tony suggested.

Now you will have to work out the length of the arm, the length of stroke of the piston, and the diameter of the cylinder to allow the development of the required torque with reasonable air pressure. SolidWorks can do much of this for you. The longer the arm, the greater the mechanical advantage but the longer the cylinder stroke has to be. The tradeoff is between stroke length and required cylinder force. Position the cylinder mount so the line of applied cylinder force is as close to a right angle to a line between the pivot point on the arm and the pivot point on the press for maximum force.

It looks like an interesting and fun project. Back to the drawing board!
 
Thanks to all for the important feedback. I'll use Tony's and RJ's feedback to get back to the design and rework the implementation.
I'll be back with updates in awhile.... along with more questions.

Thanks
