Un-Jam your Strippit Super 30/30 & Custom 18/30 Punch Press Machine Un-Jam-Strippit-Super-30-30-Punch-Press-Machine
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.
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,  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 Wood-Box Holder-Places for my  1 1/4"   &   3 1/2"  Swing-Arm Holders.
Because 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  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  --   Carefully  Reinstall the  Ball  &  Set-Screw,   Don't Cross-Thread Screw!

7  --   Using    #49579-000   Punch-Head  Dip-Stick,   
         Refill   Punch-Head  at   Bottom-Dead-Center   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. 
        Try Not to Electrocute Yourself.

You should now be Back in the Punching Business!    Be More Careful 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, 
Pre-1977  Super 30/40-Mechanical  and  Custom 30/40-Mechanical Machines.

After  1977,   Super 30/40-Hydraulic  and  Custom 30/40-Hydraulic  Machines
were  Redesigned to be  Completely  Hydraulic  Punch 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.

And Remember,
Don't Let Your Women Have Chewing Gum!
The  Cut-Away View of the Above Ram can be Confusing as it is a
Side-ViewNot  the  Front-View  that would  Face-You
with the Ram in your Machine.

Set-Screw of Relief-Valve  is  Actually on the  Left-Side of Ram,
in the Area where the  Notch  or  Cut-Out  of  Casting is
when the Ram is in Machine.

Sometimes it is Hard to find the Set-Screw Hole
as it is probably filled with a Half-Century of Grease and Dirt.

Also,  Be Aware that this  Assembly  and  Parts
Changed  and  Evolved  somewhat
over the  4-Decades these Machines were Built!

You Actually do Not have to Back-Out and Remove  Set-Screw and Ball,
All the Way Out,  to Release Oil Pressure.

As you Slowly Un-Screw Set-Screw,
The Ball will Move-Down with Set-Screw,
and  Un-Cover  a  Small  Drilled-Hole  Passage-Way
where the Oil will Shoot Downward Releasing Pressure.

You can See  Small  Release-Hole  in the
Above  Ram Cut-Away View   and in   Photo Below.

Also,  In our  Punch-Head Rebuild Kits  we have  Changed from a
Cup-Type Set-Screw  to a  Extended-Tip  Set-Screw 
as we found on some Machines the Cup-Type Set-Screw
did Not Push Ball into it's Seat Tight Enough
so then it would slowly Leak Oil.
Extended-Tip Set-Screw  Fixes this Rare Problem.

Punch-Head  Rebuild Kit
is Shown Below.

Set  Oil  to  Correct-Level  at 
Bottom-Dead-Center  with  #49579-000  Dip-Stick!
