The Cincinnati CB350 press brake thread. Moving and install.

rofl
I was gonna suggest a chainfall to the top of the mast if it didn't

thing being so close in to the lift makes all the difference in the world
do not tilt it back forward until you're right in there against where it'll live its life, once it starts tipping it's going over
not that you need to be told

I thought about how much it would suck to go over. Not so bad is the tipping crashing part, but when the battery comes from behind to kill you.

Bed went on without issue. I had to put some more shims under it because there's a bump in the concrete and I didn't think it had enough clearance. I need to do the final leveling and start on the platform next.

Ran some 2in conduit, #3 wire, and made a static phase converter. It starts up, abit hard starting maybe 5 seconds to get spun up to speed. I think i need to play with tuning the capacitors some. Right now its got four 430-516uf caps in parallel.
 
Now I understand the pit and why you built it up on beams. Took a minute studying the progress photos in its former location. Luckily you had the ceiling height to accommodate. Looking really good. Excited to see it run myself.

Reminds me of working in the shop.

The Lvd, cincinnati, and lodgeshiply just cycling away on a quiet night shift.

Except the Shipley. That big flywheel clutched bastard let everyone know something big was coming through

I worked at a shop that had old WW2 flywheel machines
I hated those things

line everything up
check it
check your clearance around it
check where your hand are
check to see if anyone is going to be walking by
check your hands again
make sure your chin is clear
step back
click click click click click close your eyes CLICK KABANG
open eyes
count fingers

:laughing:

That must of been a dog clutch machine, spec'd for punching/stamping operations.

The flywheel stuff i have has clutches and you can slip them into the bend. The big Chicago has an air clutch thats hard to feather. Was also originally spec'd for punching/stamping type work. I was going to sell it after getting this, but I don't think i will because its just so fast for channel and stair pan work.

gonna put a little rack on it to hold the dies stacked right up close to the bed?

I see that done but I don’t really like it. I sometimes get into some weird shapes that might get into that space. Down low is probably ok.

Die storage is becoming an issue, and now ive got to figure a good way to swap them without the overhead crane. Also need a crane in front to hold material so something needs to be sorted out.
 
Our press was up high like that. We pretty much always worked off the forklift forks

way down low and close in
then the two holes up top, couple chains with grab hooks, two more in the dingus up above that stays stationary
ram down, chain tight, ram up, swap chains, back and forth until it is up high enough to drop into place, might take like ten cycles though

or maybe drill and tap holes in the ends of the dies, then use a couple lever chain comealongs on the sides going up to something or another, lets you set them into place without the chain around them getting in the way

If you zoom in, there's pins on the end of the ram used for lifting 4 way dies. Only good for full width stuff. Most of the tooling is 12' and 10' with misc smaller stuff.

I was thinking little jib crane off the corner of the platform, or just go a build a crane off the top of the machine. Sucks I have overhead steel but its not good to use for lifting stuff because its holding the house floor at max capacity.

Usually you want to load dies from the side and slide them in.
 
I ran a punch press stamping out washers when I was young, It took huge sheets of steel an stamped out washers. It rocked the budling when it ran.

Then they promoted me into the maintenance area, The guy they fired forgot to set the magnetic table before sharpening the dies, sent them all into the wall like lawn darts. I guess not the first time :laughing: :laughing:

That is one huge machine,.

I think you are right
I dont remember the specifics, I can tell you that when you pull the trigger the bullet has left the gun and you are not getting it back
I think it seemed more intense as we were breaking full sized sheets
from what I was told they were leftovers from the Boeing plant

They had a big punch press too that was equally as terrifying :laughing:

that's where I got the idea
surely there's a half ton's worth of capacity left in those beams especially if you allow for a little bit more deflection

Probably be fine but its deflected, bouncy and I know ill use it for stupid if its there. Was supposed to be additional capacity but the concrete guy did 8" instead of 5" or 6" and used that all up.
 
Looking over the tooling and the 60° or whatever die is fawked, thats one worn out V. Second pic is the other end that didn't see as much use.

The other die is ok, but an odd size, and punches are decent condition. The goose is a good score. I need to go back and spend some time to pick some more out. Dies are $$$.
