![]() ![]() ![]() It's really nice to see others besides myself working on similar projects and goals -this site is a real asset in that manner - it's a real morale boost for me and makes me want to get back to the project! I had initially thought i could build mine for 1200$ -> Wrong! It doesn't take much for a surprise to boost the final cost. Your price range estimate could be a little low if you aren't super careful about your component purchases. I have been patiently building up all the components over the last year as I run across them cheap - or free. Mine will be closer to 50T though with dual 5" cylinders. If you upgrade to 5" cylinders and a bigger pump - it would be something to consider.ĭerek - I've probably spent close to 2000$ in materials on my build also. It looks like the top and bottom frame plates are only through bolted? Personally, I'd run a pass of weld up the vertical angle iron to the frame plates to reinforce them (and probably use larger grade 8 bolts -lol). I have a tendency to way over engineer things - so maybe this isn't an issue - but I'll ask. Your 2 cylinders are spaced symmetrically even with a centered tool die - so with your good guide setup - hydraulic pressure will find equilibrium and the rams will work in unison. Synchronization isn't a concern for your build in my opinion. The GPC has been implemented in the control system of an 80 MN industrial hydraulic forging press.I'm making something very similar to your build - but using 6圆 I-beams instead of angle so that the frame can be used as a guide in a slightly different manner. Real-time model predictive control (MPC) was developed based on multiple inputs multiple outputs (MIMO), and global predictive control (GPC). An energy-saving control for the hydraulic forging press based on the forging process parameters’ prediction has been developed. A simulation model of the 80 MN hydraulic forging press is presented, which is useful for determining the time-varying parameters during the forging process. The predicted forging force as a function of heavy steel forging heights for various deformation temperatures and strain rates was determined. The energy-saving power supply of hydraulic forging presses consists in reducing electricity consumption by the electric motor driving the pumps, reducing the noise emitted by pumps and reducing leaks in hydraulic piston cylinders. Three innovative energy-saving power supply solutions useful for industrial hydraulic forging presses were analyzsed. The study deals with the energy-saving process of hot open die elongation forging of heavy steel forgings on an 80 MN industrial hydraulic forging press. ![]()
