Reading this forum was very helpful in getting ideas for building my own press so I thought I'd show what I came up with. Since my space is limited I wanted something with a small footprint. I ended up with a benchtop forging press that suits my Damascus steel making needs perfectly. After lots of research I decided to focus on speed rather than tonnage. The result was a 19 ton press using a 4" cylinder with 2.25" ram. To keep noise to a minimum the motor & pump assembly are mounted independent of the press. I also mounted the pump on a shop built bracket made from 1" steel plate to reduce vibration. Power comes from a 7.5 hp electric motor driving a single speed 6 gpm vane pump. Ram speed is ~2" per second. I'm currently running the press at under 1500 psi and making ~12 tons which (to my surprise) has been plenty for my initial 6x2x3 billets. Here's a very brief action video. https://www.youtube.com/watch?v=RUUsILQZq4s The design is pretty self explanatory but any questions are welcome. Thanks for looking, D. Crawford
is it possible to build a hydraulic forging press for under 200 dollars, a mini one, like this picture, because i dont got much room?
Hi guys and I'm sure a few Lady's, I am at the very BEGINNING, of the process, of building a Hydraulic Forging Press. As with most everyone money is tight, because of that, and the realization that I do enjoy and get satisfaction out of building my own equipment, I decided to build my own Hydraulic Forging Press. I have decided on the vertical set-up, using an I beam as the foundation, the cylinder is attached to the top of it with the clevis pins, then there is a shorter I beam that is welded directly in front of the main beam, where the bottom dies are attached. I'm not sure if anyone has seen this type of configuration for a forging press, the problems I'm having are which parts should be purchased first, I'm a bit apprehensive about buying any certain part and then getting cornered into having to use specific parts that I may not want, or find a great deal on another part and find that the 2 aren't compatible. I'm starting to think I may be over thinking this, or worrying too much about losing a few dollars. I do understand that i will have to spend some money to build this, I am not niave to the fact that this stuff is not cheap, but I also know that with a little bit of determination, armed with knowledge and a little help from anyone I can get it from can go a long ways to keep what little money I do have and still be able to build a quality machine. So I'll ask my question like this. Are there parts that are more important to buy first? What experiences have any of you guys had with cylinder strength? The formula I found uses the bore and rod sizes, it's actually a calculator I found on Surplus Center's website. So far, what I understand is that the rod size needs to be a minimum of 2 inches (in order to get the amount of strength I want), I am trying to save up for a cylinder that has, at the least a 4 inch bore, 5 would be much better, but I haven't found any with a 5in bore that were affordable. I don't have all of my notes with me, but I have a fair understanding of what I want to do and I hope that maybe someone here might be able to shed a little more light on this subject. I do want it to have around 20 tons of mashing power. I would settle for a little less, like somewhere between 15 and 18 tons, but I don't want to go any less. I have found the cylinder for this, which would cost less than $200 at Surplus Center, I can't remember if it is a 2500 psi or 3000psi, which brings up another question, which one is best? 2500 or 3000? And, If I have a 3000psi pump and get a 2500 psi cylinder, will that work together? Here's another question I was wondering about, do ALL the parts have to be rated or "related" (to or) for each other? I'm not sure if I'm asking that question the right way. I've seen so many parts, and pieces that go to this build, 1 being the valve. I have heard that a regular Log Splitter valve will work, but I don't know what the correct terminology is, for that type of valve. I would like to be able to have all the correct names/terminology so that I can shop for the items I need, again to be able to save money. I know I will have to spend money to build this thing, and I don't have unrealistic expectations, I just want to find the best, most economical way to do it, and when I get done, I plan on having a list of all the parts and where to get them, where I found the best deals, where maybe someone else can benefit from what I learned and be able to build one as well, Thanks for any and all help I can get from you guys, I appreciate the fact that so many of you will stop what you're doing in your busy day to help out us Newbs, to the world of HOT STEEL! Thanks Again, Rex
