Damascus Mike Posted May 26, 2009 Share Posted May 26, 2009 hey guys ive got a little question i need to ask,im interested in small presses and i was wondering if its possible to make a small press some how using an electic motor to force the ram down thanx Mike ps:ive searched it and cant find ANYTHING on the subject Quote Link to comment Share on other sites More sharing options...
johnptc Posted May 26, 2009 Share Posted May 26, 2009 usual is to have the motor spin a hydraulic pump Quote Link to comment Share on other sites More sharing options...

matt87 Posted May 27, 2009 Share Posted May 27, 2009 Electric motors work by spinning an axle. How do you intend to translate this into longitudinal (forward-and-backward) motion 'with only a motor no jack or cylanders or anything else just a motor'?

nonjic Posted May 27, 2009 Share Posted May 27, 2009 you could attach the motor to a handle and whack the billet with it? :rolleyes: Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted May 27, 2009 Share Posted May 27, 2009 DMike: I googled Friction Drive Screw Press and almost all the hits on the first page were applicable. May I suggest you do likewise. I have to get ready for a road trip back June 1st. I have a friend who is a coiner and has an old FDSP that I have used---bought on the used machinery market and much cheaper then the new imports and better made to boot!

Dodge Posted May 27, 2009 Share Posted May 27, 2009 DM, another thought, if available to you, is to enroll in an industrial arts class. It may teach you some basic physical mechanics to learn how simple machinery works and doesn't work. Electric motors are generally useless without some sort of mechanics; hydraulics, pulleys, gear boxes etc. to drive. Otherwise, they just sit and spin.

Any other ideas?if there is no way to do it i can use my bottle jack if needed i just need to know how,im very keen on the press that has a motor running the hand pump up and down with a cam but im not sure if ill get it right.

welder19 Posted May 28, 2009 Share Posted May 28, 2009 What's wrong with a jack or cylinder? Hydraulics are the best way to opperate a press, if you are against them then what did you have in mind for your press mechanism? You could build a screw press or an arbor press but I don't see why you would want to power either of them with an elec. motor. What are you wanting the press for? forging or just a shop press? Try searching on google for homemade presses or something similar, then you may get a better idea of what you want to build or atleast get a better understanding of different style presses welder19 Quote Link to comment Share on other sites More sharing options...
Phil Patrick Posted May 28, 2009 Share Posted May 28, 2009 A little off topic, but somewhat interesting. The company I work for manufactures brake presses. We use what is called a planetary roller screw for each side of the ram of the press brake to drive it down. It gives us quite a bit of available tonnage, plus a very quick cycle of the machine.

The press will be an H style press with the jack in the middle under the bar that goes up and down i want the jack to have my motor atached to it running the hand pump up and down making it pump the ram up very fast.If you have any changes or tips to make it better and faster fell free to comment.The press in the pic is what i wanna make.

nonjic Posted May 30, 2009 Share Posted May 30, 2009 Just make sure that you build the frame twice as strong as you think it needs to be. If youve no experience with presses you probably cant get you head around just how much energy is stored up in the press frame. It can go bang very easily.

Yes thanx,i plan to make it from I beam and square tubing and on every join or weld ill have another piece overlapping it so i know it wont break Quote Link to comment Share on other sites More sharing options...
Nakedanvil - Grant Sarver Posted May 30, 2009 Share Posted May 30, 2009 Phil Patrick: Thanks for the information! I Googled it and found a lot of information. They certainly would be a good basis for a press. Thanks again! Quote Link to comment Share on other sites More sharing options...

Sam Salvati Posted June 1, 2009 Share Posted June 1, 2009 Mike, what type of welding are you trained/learned in? Quote Link to comment Share on other sites More sharing options...
Damascus Mike Posted June 1, 2009 Author Share Posted June 1, 2009 Arc welding,Mig welding,gas welding,soldering and still trying to get forge welding right.why? Quote Link to comment Share on other sites More sharing options...
nonjic Posted June 1, 2009 Share Posted June 1, 2009 Arc welding,Mig welding,gas welding,soldering and still trying to get forge welding right.why? im guessing coz if you get it wrong you could maim or kill yourself, or someone else if they are nearby if the frame lets go due to substandard welding. At this stage I think your time and resources would be much better spent on getting the basics down (hot forge, decent materials, 15n20 etc) than making a press. just my 2c.

Frosty Posted June 1, 2009 Share Posted June 1, 2009 Why Mike? If you have to ask you don't know enough about welding to try building something as serious as a press. Frosty Quote Link to comment Share on other sites More sharing options...
Damascus Mike Posted June 2, 2009 Author Share Posted June 2, 2009 Why Mike? If you have to ask you don't know enough about welding to try building something as serious as a press. Frosty What are you talking about?it doesnt mean that because im good at welding i must also know how to design a press. Quote Link to comment Share on other sites More sharing options...
Frosty Posted June 2, 2009 Share Posted June 2, 2009 I meant exactly what I said. If you have to ask why it's important you are NOT a weldor anywhere but in your imagination. Frosty Quote Link to comment Share on other sites More sharing options...
Finnr Posted June 2, 2009 Share Posted June 2, 2009 Gotta agree with Frosty on this one If you KNOW what you have to have for constructing the press and what it takes for proper welding THEN you are a welder. Finnr Quote Link to comment Share on other sites More sharing options...
Damascus Mike Posted June 3, 2009 Author Share Posted June 3, 2009 Ok this is seriously not making sense, the question what about making an electril press and then i changed my mind and decided im gana built a jack press, now where did welding come into the story???????
