Underpowered 50 ton forging press

Thumbnail

24 Upvotes

Hey. I bought this “50 ton” press for forging and it functions at a high rate of speed like I need, but it’s underpowered. It’s a 5 hp 3450rpm @230v motor. At maximum force the gauge reads 650 psi. I’ve got a 50 amp breaker. 36” ram with 4.25” bore. I’ve tried googling this and I get a wide range of answers on motor size. Looking for suggestions from the experts here. 10 hp motor? Larger? 1700/3400 rpm? Do I need a larger pump?

I can install a larger breaker if need be. The hoses are all new. For now it’s working well enough for bending and straightening, but I primarily bought it for punching and drifting holes in hot metal and it just doesn’t do that well. I appreciate your insight.

Hydraulic cylinder gland removal

Thumbnail
gallery
5 Upvotes

I’ve been battling this Ognibene cylinder off of my Farmall 75A with a L610 loader. The gland has the 2 flats to put a big enough wrench on it. In my case a 24” adjustable wrench that I modified to open up to 3 inches.
I thought it would be an easy job but boy was I for a good surprise.
I’ve rebuild my share of different style cylinders but this one has brought me down to my knees. I went around where the gland meets the barrel with a razor blade to break off the paint in between. I’ve tried peening around the barrel where the gland screws in. I do not see a set screw anywhere. I’ve applied heat(up to 300° as I don’t want to do unnecessary damage) hoping that if it’s got some kind of thread sealant it will loosen up and tap on it as I’m trying to turn the wrench but nothing.
I’ve been working on this after work and by the time I get home the garage is 100 degrees.
I don’t know what else to do
My last resort will be a pipe wrench or weld a nut on the flat so I can hit it with a punch
Any more ideas would be appreciated!

Is this normal? This gland has a film peeling off that I haven't seen before. Should I just remove it and test?

hydraulic pump failure cost me a week last season

6 Upvotes

Lost basically a whole week last season when the hydraulic pump let go. parts hurt bad, thousands before you even count downtime. ngl rough week.

Signs were there for a while. I just didn't know what I was looking at.

Boom got sluggish on empty cycles first. never timed it, just noticed things felt lazy before I even loaded the bucket.

Found metal fuzz on the magnetic drain plug one oil change. should've paid attention sooner, that stuff doesn't show up for nothing.

Arm started drifting in neutral, slow creep I wrote off as an old machine thing. wasn't.

Oil was running hotter than usual and rattling under load I blamed on the frame. ignored all of it too long.

Could also be valves, cylinder seals, or a clogged filter, same symptoms. pressure test before you pull anything expensive. I skipped that.

Which sign tipped you off early?

What to do with an old cylinder?

2 Upvotes

Got some major leaks fixed on an old truck mounted conveyor. Owner didnt want the old leaky cylinder. Normally I'd just take it to the scrap yard but this thing is like 5 feet tall. Seems wasteful just throwing it away. Is there a better way of getting rid of this thing? Don't think too many people are in the market for this kinda thing but I thought I'd ask haha

Bulkhead Fitting Question

2 Upvotes

Hello, everyone!

This is my first post in this subreddit and I am by no means a hydraulics expert.

I am working on an application that has a tank that holds transmission fluid at low pressure (<100PSI). I want to drill holes into the tank and install two bulkhead fittings with 1/2" NPT female ports on the outside so that I can install IFM (LMC510) sensors to detect high and low levels of fluid in the tank.
(I would prefer to avoid any welding options, if possible.)
I am considering buying one of these two parts for that purpose...

  • PARKER HANNIFIN (207ACBH-8)
  • MCMASTER-CARR (50785K275)

But I want to ensure that these connections do not leak fluid, of course. Would they leak fluid if all I installed were one of these parts above? How are hydraulic bulkhead fittings normally sealed? Does anyone have any resources I could read/watch to understand hydraulic bulkhead connections better?

Any information or guidance is greatly appreciated!

Is it stupid to buy a used motor?

2 Upvotes

Hey Im doing a hobby project where I need 2 hydraulic motors (I’m trying to build a small tracked vehicle from scratch) I already have one used Danfoss OMP 200 from where I were an apprentice, and I found a used one online. I’m unsure if it’s a bad idea to buy a used motor though, if anyone here has experience with buying used hydraulics parts how have that went? I would buy 2 new motors, but I’m a student so I can’t really afford them sadly.
Is there a way to test or gauge their condition?

Building a forging press. Got a question.

2 Upvotes

Hard thing to Google apparently. Getting components together to build a forging press. Do I need to match the fitting/port types, or can I work around it using adapters? It's hard to find the parts I need in Australia, but nearly impossible to find them with matching fittings.

For example, here are links to a cylinder and valve I'm looking at.
The cylinder uses 3/4" NPT ports, whereas the valve uses 1/2" NPT ports.

Cylinder: https://www.hydraulic.online/5-Bore-Budget-Imported-Hydraulic-Cylinders-Various-Strokes-p563625601

Valve: https://www.ebay.com.au/itm/335427713523?_trksid=p2332490.c101224.m-1

Thanks.

Will this hose hold?

What are the chances this hose hold up for a power steering pump?

Any idea what the parts store is doing wrong?

When I told them it was wrong. They said this is how the 3/8” hoses all crimp. But only 3/8 the 1/4 and 1/2 are straight and seem correct.

Help with car lift cylinder

Thumbnail

1 Upvotes

I am installing a mobile single post car lift for my garage. I am almost done but I can't get the lifting cylinder to sit flush.

The chain is aligned on the pulley and the chain is held to the carriage base with a retainer pin (photo 2) and held to the lifting arm with another retainer pin (photo 3). There is no chain tensioner that I can see. The lifting cylinder and chain came installed to the carriage as shown in photo 1.

I can move the cylinder to the flush position by hand put then it just falls forward as soon as I let go.

Would appreciate any advice.

Excavator hydraulic pump, pressure?

4 Upvotes

Looking for some direction from you expert folk. My small Chinese mini excavator gets stuck. The treads aren't skipping, it's just like it has no power to move forward or backward more than a few feet. But the bucket and arm seem to move fine. If the pressure is too high could the hydraulic oil (46) overheat within a matter of minutes to the point it wouldn't drive forward or backward but bucket works fine?

Or is it something else entirely?
