basher Posted May 13, 2011 Share Posted May 13, 2011 firstly I would like to thank all the people here for there great information on this subject . I finally built a forging press . I have been gathering bits for a while and figured the only way to know from all the various ram /pump configurations is to go ahead and do it .all the theory is great. so from bits I have gathered I built a press . 10hp single action pump at 3.5gpm 4" ram. it is an inch a second under power . topps out at 3000psi .and is quite , no screech . I think the motor could handle a bigger pump possably a 5 gpm but as it is there is no strain on the motor so thats good and quiet . I calculate its putting out around 16 tonnes which is great for punching and hot forging but shows its limits on thin or cold steel. I have quick change dies and already have numerous dies made. the cost so far pump and motor £80 ram £40 valve (new) £70 tank £30 , plumbing about £150-200 steel from my pile... .maybe £150 all in around £600 in bits and 3 man days . I have had an electrical engineer design a switch system that will let the press cycle full auto to fixed stops to speed the forging process up a little ......

Marksnagel Posted May 13, 2011 Share Posted May 13, 2011 Nice job. An inch a second, mind the fingers. Looks great. Good luck with it. Let's see some pics of your first pieces when you get them. Thanks for posting your progress. Mark<>< Quote Link to comment Share on other sites More sharing options...
HWHII Posted May 13, 2011 Share Posted May 13, 2011 Nice work! You will have alot of fun with that. Time to get squishy :lol: Quote Link to comment Share on other sites More sharing options...
macbruce Posted May 13, 2011 Share Posted May 13, 2011 Nice press........I wouldn't make it go any faster.An inch per second is cookin'. I'm sure the 10 hp can handle it and to my way of thinking speed isn't necessarily what it's all about with a press. If it were mine I'd use a flow control so it go slower when needed.......Or not...........Have fun! Quote Link to comment Share on other sites More sharing options...
ianinsa Posted May 13, 2011 Share Posted May 13, 2011 Oh boy Basher, I bet that'l crush a coke can no hassle Nice press! Ian Quote Link to comment Share on other sites More sharing options...
basher Posted May 17, 2011 Author Share Posted May 17, 2011 thanks guys, the motor is on a speed control and has enough power to make pressure at 1/4 speed so its not too fast. the low tonnage helps to act as an auto stop and I have not managed to totaly ruin anything by over pressing yet. I have found its limits pretty quickly . these are great tools and I have wanted to make one for years but lacked the hydraulic knowhow.
