Mount for the hydraulic jack.. Turning it upside down.

[Tuomas]

Wanted to add bigger jack to my press.
To get most of the pressure to the small area, i decided to turn the jack upside down.
This way i can mount hole punching and stamping dies directly to the cylinder of the jack.

In use:
Attachment 23111

Stored:
Attachment 23110

Takes about 10 seconds to assemble / disassemble.

Springs are surplus from trampoline. Bigger holes drilled with a variable wood cutter, with diy hss blade.

Used cheap 8 ton jack that was sealed with welds.
Actually this should work with "any" jack, without need to open it.

Here is the video:

More info:

Picture shows how springs goes between the rods that hold the jack

Jack mount is locked on its place with two M8 screws. Lid in front is weld to the mount...

Attachment 23113

Latch on the back is bolted to the press frame..

Attachment 23115

This is the reason why i welded similar plates to the bottom and upper bars of the frame..

Attachment 23116

I can use same dies with both jacks.. when i need to bend thicker materials i use bigger jack..
With thinner ( <5mm ) i use smaller one, wich is more accurate and faster to use.

Attachment 23117

I used surplus cutting fluid container as a oil container,
for mounting it to the press, i used clamp that's originally intented to connect flashlight to the welding mask.

Hose clamps..

And why i originally wanted to add this jack to my press.. i had this idea in firts place when i made the original frame, but no i needed it. So, i made it.

For stamping sheet metals. These are going to be reflectors for small leds. I got idea from Tony Foale, i decided to place dozen small led spotlights to my shop where i need more light.

Edit:

New container:


Fitting. Didn't find suitable, so i made it from bigger one, cut the end out and welded piece of 6mm ( hose is with 6mm inner dia ) thick pipe to it.



Connections..



Cap is made from a bolt. I filed groove to it, it allows container to breathe.



Open..



Closed.. When stored, so it doesn't leak if it falls.



Easy to fill..



Ready.



I used this hose in that first version. Now i changed it to appropriate one...



But at that time, i had any hose and stores we're closed. So, i improvised.
I peeled it from electric cable. It worked nicely that time i used it, but i decided to change it before it breaks.

I tried using one on its side but it wouldn't work

All air needs to be removed inside the jack.

20 ton press. Jack is inverted same way as shown on the video above.

This time oil tank is integrated to press frame.





12mm plate and 160 x 60mm u-channel with 12mm wall.
Should handle bigger jacks too.

Nice to see the incorporated tank and more versatility in Jacks is a bonus! Thanks Tuomas!
