Strippit
Super 30/40HD
Punch Machine Notes
Super 30/40-Mechanical Machines were made in 1960's & Early 1970's.
These Machines were basically just a
Super 30/30 with Bigger-Flywheels and Larger-Motor
and were Definitely NOT Good 40 Ton Machines!
Shops that insisted on Punching Large and High-Tonnage Holes with
Super 30/40-Mechanical & Super 30/30 Machines would, sooner or later,
Break the Piston and other Punch-Head Parts.
If you have a Super 30/40-Mechanical Machine,
I would NOT Punch Holes that Required over 25 Tons and I would
NOT Punch 1/4" and Thicker Material as Replacement Pistons are NOT Available.
So if you Break-it, you will need to Buy another Used Machine to Replace your Broken Machine that you can't repair, or else you will have to Run-Down to Home Depot
or Lowes and Buy a Hand-Drill to make your Holes. Your Choice.
Because of these Breakage Problems with Super 30/40-Mechanical Machines,
Strippit Replaced it with the Super 30/40-Hydraulic Machine in 1976.
These were Excellent Heavy-Duty Machines
that would Punch 40-Ton Holes all day long with No Problems.
Strippit Stupidly Quit making these Excellent Machines about 1990,
and
LVD-Strippit STUPIDLY No longer makes Any Single-Station Machines.

As stated previously, these were Excellent Machines.
But, of Course, there are some trouble areas now that they are getting old.
1 --- Machines are now about 30 to 45 years old. Do You Do ANY Maintenance???
Did you EVER Change the Hydraulic Oil??? Yeah, I didn't think so.
So the the Hydraulic Oil in your Machine is now at least 30+ Years old.
But yet You wouldn't Dream of Not Changing the oil Regularity
in your Pick-Up Truck or your Wife's Caddy for Decades. Go Figure.....
That Old Oil has Dirt & Water & Metal Particles in it that has Been Wearing-out
your Expensive Hydraulic-Pump, Hydraulic-Valve, Punch-Cylinder, Seals, etc.
Hydraulic Tank holds 55 Gallons of Mobil DTE-24 Hydraulic Oil.
Change The Fucking Oil!
2 --- Strippit really Screwed-Up here. They put a Course Screen-Filter that will
Stop Cock-Roaches & Floating Mice going up the Suction-Tube Pick-Up in
Oil Tank that goes to Pump. But it will NOT Stop & Filter-Out Dirt & Metal
Particles in the oil that will Damage All Components in Punch System.
Common Good-Practice in Designing Any Hydraulic Systems is to put a
Spin-On Filter in Return-Line from the Hydraulic-Valve.
Hydraulic Systems, like on this
Super 30/40-Hydraulic Machine, have the Pump Running and maintaining
Oil Pressure to the Punch-Valve All the Time when Machine is Turned-On.
If not actually Punching at that moment in time,
Valve just Dumps the oil through a Return-line Back-to the Tank.
A Low-Pressure Filter should be Inserted into that return Line!
But Strippit Did NOT put a Return-Line Filter on this Machine!
95-Percent of the time, Machine is Not actually Punching, so the oil is constantly
being sent back to Tank. If you were to Add a Filter to the Low-Pressure
By-Pass Line coming out of Valve, your Oil would be
Constantly Filtered Clean Preventing Many System Wear-Out Problems.
Pictures of Typical Small Filter-Mount & Filters are Shown Below,
but I would use a Much Larger Filter to handle output from
this 10HP Motor & Pump Combination which Flows About 19 GMP.
or
or equivalent.
If I owned 1 of these Machines, I would Plumb-in a Filter Assembly!

3 --- Back-In-The-Day in 1975 when Strippit's Engineers built the 1st
Super 30/40-Hydraulic Machine, Engineer's put the 2 Hydraulic Hoses to
Punch-Cylinder on Outside of the Frame where they would be Easy to get to.
Then Strippit's Marketing-Pukes looked at it and said
"Move & Hide The Hoses because they weren't Pretty!" True-Story.
Remember Strippit's Marketing-Pukes when you Try to Un-Screw or Replace Hoses.
So Hoses were moved inside the frame where they are impossible to get to!
Every time you Punch with these Machines, the Hoses Jump & Flex, Inside the Frame,
from Punching Pressure Cycling on & off. After many years of this,
Hoses can Wear & Blow-Out, and are Extremely Difficult to Access and Replace.
You will have to drop-down the Heavy Punch-Head to get access to hoses,
another Very Difficult Operation.
If you are replacing them, Take Old Hoses to a Good Hydraulic Supply House like
and make New Hoses out of Premium 4000PSI or 5000PSI Components,
do NOT use the Cheaper 2000 or 3000PSI Stuff!
T-SAF 30
Later-On, in the Early 1980's, somebody in Strippit's Marketing Dept.
had a Wet-Dream in the Shower, and came-up with the Idea of
Bolting a Tool-Turret on the Side of this Excellent Single-Station Machine.
So Strippit Did. A 12-Station Tool Turret Was just
Bolted-on to the Left-Side of the Frame, and a Very Clunky Indexing Mechanism
would advance the Turret Very Slowly & Very Imprecisely 1 Station at a time.
This New Machine was called the T-SAF 30.
These Crappy Machines had Many Problems, so Avoid Them!
4 --- As All these Machines are now Decades old, Cylinder Seals tend to become Brittle with Age after 20 years or so, Wear-Out, then Crack & Break into pieces causing Punch-Cylinder to leak lots of Oil at the bottom of the Punch-Ram.
Cylinder-Bore may need to be Honed-Smooth if it's Scored from Dirt & Contaminants because you Didn't Change Oil regularly or add a By-Pass Filter.
Unfortunately, it's a Big-Job to Replace Seals.
Alan Suda, in the Mid-West may do this work if he's in The-Mood & has Time,
and Tom Penrod, on the West Coast can also do this work.
Both are listed on my Independent Strippit Machine Service Webpage
Otherwise, you will Need to do this yourself.
Depending on how far you need to go on Taking this apart, Getting Repair Parts, CleaningUp or Possibly Honing the Cylinder Bore, Etc., Budget a few days to do it!
Before You Start, Take Photos of Everything, Especially Switches & Cams,
to insure you get it all back together Correctly!
Drop-Down Cylinder Assembly onto the Machine Table, take-off Hydraulic Hoses,
take-off Tool-Holder Base-Assembly and Cylinder Rod-End.
Some Shops will Pull the Cylinder out and send it, with a New Set of Seals,
to a Hydraulic Repair Shop to be rebuilt.
Be Very Careful, as the Big Oily Punch-Cylinder Weights a 1/4 Ton! Don't Drop-It!
1 of my More Clever Customers rebuilt his Punch Cylinder in only 1 Day!
He maneuvered his Fork-Lift Forks under Punch-Head to Lift it Down & Move it.
A Problem of rebuilding Cylinder is Holding it while Loosening & Re-Torqueing
the 4 Big Tie-Rod Bolts, as they are Torqued to 850 Foot-Pounds!
He put a Wood 2 by 4 (2 by 6's might be Better) in his Press-Brake Lower-Bed,
laid Cylinder on 2 by 4, then put another 2 by 4 on Top, then Carefully Bumped-Down
Upper Press-Brake Ram until Cylinder was Secured in the Brake like a Giant Vise!
Again, Be Very Careful, as the Cylinder Assembly Weights a 1/4 Ton!
When Done Rebuilding Cylinder, you will Need a
to achieve the Required 850 Foot-pounds of Torque on the 4 Tie-Rod Bolts!
5 --- Try to Not Damage Switches as they are NOT made anymore!
Take Very Good Photos of Limit Switches & their Set-Up Before you take them all off!
If you are completely Disassembling the Cylinder, the #11 Switch Actuator Rod is
held-on to Piston only by a Item #10 Retaining Clip. I had a Machine where the Clip
Popped-Off of the Piston so Switch-Rod became Loose.
Customer had to Completely remove Switches, Pull Cylinder, sent it to a Rebuild Shop, and then reinstall everything back in Machine.
Then Switch Actuator Rod Popped-Off, Again!
Customer had to Completely remove Switches, Pull Cylinder,
send it to the Rebuild Shop, Again.
It took a Month and Many Thousands of Dollars to get this Machine Finally Repaired, All over a 50-Cent Retaining Clip!!!
It should be OK, but check the Clip Groove on Piston to see if it is Buggered Up!
Re-Machine if somehow damaged.
And Always fit a NEW Inverted Retaining Ring (Snap-Ring) in Piston-Groove.
Special Inverted Retaining Ring is used because a Standard Retaining Ring (Snap Ring)
Lug-Holes stick-out too far and would hit the #11 Switch Actuator Rod.
2 of these Special Rings are Included in our Seal Kit!
5 --- There are No Electronics in a Super 30/40HD Machine.
Just the Punch-Head Limit Switches and Several Relays.
Strippit Engineering was Confused by some New U.L.-Insurance Requirements
in the Late 1970's when this Machine was designed, and so
Relay Logic is Much More Complicated than necessary,
and can be very difficult to follow.
I replace Stock Relays with Special LED-Light Type Relays
which Light-Up when the Relay is Pulled-In,
making it Much Easier to Follow & Trouble-Shoot Problems.
6 --- For Un-Know Reasons, Strippit Stupidly made the Cams that go on the
Switch Actuator Rod out of 6-Sided Hex-Bar-Stock on a CNC Lathe.
Problem with this is the Tapered-Part of Cam actuates Switches OK,
but the Rod Rotates over time, and the
6 Flat-Sides on Strippit's Cams do NOT always actuate the switches correctly!
My solution was to have a Machine Shop make me some New Cams with No Flat-Sides!
Look closely at Cams I had made in Photos Below. I do not sell these Cams,
but if I can find my Drawings, I may post my Cam Dimensions we used, in the Future.

FC75/30
As if the T-SAF 30 wasn't Bad Enough,
Strippit Marketing had Another Wet-Dream in The Shower
and told Engineering Dept. to take the T-SAF 30 Machine and to just
Bolt-on a CNC Control to make it a Baby CNC Turret Punching Machine!
So a General Electric 1050 CNC Control & Servo-Drives were
Bolted-On to the Right-Side of the Frame.
This new Machine was called the FC75/30.
They somehow thought it would go over Big in Europe, but it never did.
But they did sell a lot of them in the U.S. Because they were Cheap.
These Machines are Automated Crap and should be Avoided!
As the T-SAF 30 and FC75/30 were Built off the Super 30/40HD Machine
The Punching-Head & Cylinder & Seals & Switches are all the Same
and use the Same Repair Parts and Repair Notes Provided Above.
Always use a
NEW
Inverted Retaining Ring!
There is Not much Clearance inside Piston
so use a Good Pair of
to get Ring in & out!
2 of these Special Rings
are Included
in our Seal Kit!
