Un-Jam Your Strippit
Super 30/30, Custom 18/30,
Super 30/40-Mechanical, and
Sonic 18/30 Punch Press Machines!
From Time to Time, Machine Operators will Overload and Jam-Up the Strippit
Single-Station Punch Machine they are Operating. Usually by, Trying to Punch
Too-Thick of Sheet-Material, a Punch Too-Large for Sheet-Material, Wrong Die Clearance, Wrong Die, Wrong Punch, Dull Punch & Die, Crossed Punch & Die, etc.
Punch will be "Stuck-Down" with Machine Not finishing Punch-Stroke,
Punch is Stuck in Sheet-Material, and Punch-Ram is Hard-Against Top of Punch.
And You Can Not Remove Sheet-Material, Punch, or the Swing-Arm Holder.
This is because you Now have OVER 30-Tons of Force Springing & Gapping
Machine C-Frame like the Large Spring that it is. And All of this Force is now
directed through the Ram to Punch and Sheet-Material,
So of course, you can not get it out!
Now this is when your Rocket-Scientist Operator & Maintenance Guys
get-out their Big Hammers & Pipes & Pry-Bars & Acetylene Torches to try
to Pry-up the Ram, Rotate Flywheels, or Cut Out Tool, to "Fix" the Jam.
Instead, they just Damage Machine & Swing-Arm Holder & Tooling.
If they Damage or Break the Swing-Arm Holder,
you are Out--Of--Business as they are NOT Manufactured anymore!
As an aside, I would Build a Very Solid-Stand Next to my Punch Machine
with 2 Good Holder-Places f or my 1 1/4" & 3 1/2" Swing-Arm Holders,
as lazy Operators usually just leave Swing-Arm Holder they are not using on
Machine Table, and Sooner or Later, will accidentally Knock-it onto the Floor
and it will Often Break-In-Two Pieces that Can NOT be Repaired or Replaced!
If Operator & Maintenance Guys Bothered to Read Machine Manual,
( You Do Have a Machine Manual, Right??? )
they would see they could-have
Simply Relieved the 30-Tons of Jammed Punch Pressure by;
1 -- Taking a 5/32" Allen Wrench
2 -- Very Slowly Backing-Out 5/16"-18 Cup-Set-Screw, Item #15, usually
Located on Bottom Left-Side of Ram.
3 -- This Un-Seats the 1/4" Ball, Item #14, acting as a
Check-Valve to Ram Oil Chamber. See Ram Assembly Drawing Below!
4 -- This allows Trapped-Oil, Under Tremendous Pressure, Use Caution!!!,
in Punch-Ram to be Slowly Drained-Out,
and releasing the 30-Tons of Force from Jammed Sprung Machine-Frame.
Frame will Un-Load and Ram should Rise as Oil is Slowly Drained-Out.
5 -- You should now be able to Remove Swing-Arm & Tooling & Sheet-Material
6 -- Reinstall the Ball & Set-Screw
7 -- Using #49579-000 Punch-Head Dip-Stick, Refill Punch-Head with
Mobil DTE-24 Hydraulic Oil, or any Good ISO-24 Weight Hydraulic Oil, or
my New Favorite Mobil-1 Synthetic 0W-20 SAE Motor Oil
Do NOT Use a Heaver Grade Oil!
8 -- Now Correct Original Problem that Caused Jam in the First-Place!!!
9 -- Also Check that the 2 Drive-Belts were Not Shredded when Jam occurred,
Replace belts if necessary. And, if Press Motor will Not Start, Motor
Overload-Breaker in Electrical Box on side of Machine probably has Tripped,
just Press-In Re-Set Plunger to Re-Set Breaker.
You should now be Back in the Punching Business! Be More Carefull Next Time.
This Simple Pressure-Relief Valve is Built-In to All Strippit Super 30/30,
Custom 30/30, Custom 18/30, Sonic 18/30, and Super 30/40-Mechanical Machines.
And also Pre-1977 Super 30/40-Mechanical and Custom 30/40-Mechanical,
but NOT Super 30/40-Hydraulic and Custom 30/40-Hydraulic Machines.
After 1977 30/40 Machines were redesigned to be Completely Hydraulic Presses.
Very easy to tell them apart as Mechanical Machines will have 2 Flywheels in front
of Machine, and Newer Hydraulic Machines will NOT have any Flywheels at all.
