Love the press Keith. You did a great job. Love the back story as well. Im planning on fixing up mine pretty soon. I have a Dake 50 ton manual press, but built a larger frame then what it came with. I want to add a pheunmatic or electric pump to it so it will be alot easier to use, like when broaching keyways.

They are held on by a series of socket head cap screws, screwed into tapped holes in each uprights, I centered the backlash and the play limits, of the frame and pinion gears so no bind could occur. With apposing gears the lift is equally loaded. ;{)---

Pressure = Force / Area ; so, F = 3,000 Lb X 29.452 SQ IN. = 58,904 LB or 58,904 / 2 = 29.452 Tons of force. The most accurate way to measure the force of your press is to put in a pressure gauge and multiply its reading by your cylinder area (19.63 SQ IN.) For example: if you are pressing @ 1,500 psi here is the force calculation: 1,500 PSI X 29.452 SQ IN = 44,178 lb of force or 44,178 / 2 = 22 Ton of force. Super press design!!

Hi Keith I have a Manley 80 ton press that has two pumps on it one goes up to 40 ton and then you use the other one. The cylinder on it is 5" so how did they get 80 ton from it I'm thinking of rebuiding it has a screw in the ram for quick adjustment but the thread is stripped out of the ram so I will have to redo that Thanks for your video

I could really use some help/advice. I'm interested in building my own hydraulic press. When I look at charts or do the calculations to pair an electric motor to a hydraulic pump, even at 5gpm and 3,000psi, I get a motor requirement of 10.5 HP. This is too expensive at this time. Can I just run a smaller motor with this pump? You running a 3HP motor, does it just make it slower than a "matched" motor would? Can a smaller motor than called for run the same hydraulic pump, just at a reduced rate of flow and still the same pressure? What makes more sense to run a hydraulic pump, and 3600rpm motor or a 1750RPM motor? I have really been struggling for a long time to find answers to these questions.
@KeithFenner
@KeithFenner 2 жыл бұрын
If you run a less than motor, you will stall the motor if pressure is excessive for the motor to handle, if I dead load mine it will stall and trip the over loads on starter and I have to reset them, hence you seeing me feather the top end pressure or pulse the valve control. A good quality motor will be the least likely component that will fail on a hydraulic press, don't look at it as one time cost, take the cost and divide it by the amount of years you plan on owning that press and that is the way you have to make sense of it.

@@KeithFenner Thank you Keith. The video was old enough I figured my post was a hail Mary. (And I have been looking at that video for at least two years) I'm amazed to have a response. Thanks! I also value the perspective of spreading the cost over years. Helps. What about the motor RPM? Is 3600RPM the way to go, or is 1750RPM sufficient?

They could do it relatively smoothly, quietly, and all day long. They were 20 feet tall, and 8-10 feet wide, and 6 feet deep. They were (If I remember right), 200 ton, and the other might have been about 150 ton. Anyone with a 50+ to press has A LOT OF POWER in their hands!!! Your Press IS QUITE the Machine!!!
