How To Use a Hydraulic Ironworker Machine:

These instructions are written for an Edwards HYDRAULIC IRONWORKER MACHINE but may also be useful for understanding how to use many other brands of Ironworkers. These instructions are written for Hydaulically operated not Mechanical operated machines, though many procedures will be the same.

Often called the swiss-army-knife of machine tools; Ironworker machines are designed to punch, shear, bend and notch mild steel plate, barstock, angle iron and pipe. A wide range of accessories are available to fabricate rod and square stock, sheet metal and pipe. While many of these machines have a pivot arm system that is pulled down by a hydraulic cylinder, the American made Edwards Ironworkers operate by applying hydraulic force to a moving center plate. The center moves within the machine frame in a simple, vertical path and exerts downward force through shear blades, punch and dies, notchers, press brake dies or bump-die tooling to work with steel. Vertical travel of the moving center allows the operator to perform multiple operations on an Edwards Ironworker without always needing to remove adjacent tooling. Though there are some dual operator machines, due to their high cost most Ironworker machines are designed for single operator use only.

IMPORTANT COMMON SENSE SAFETY PRECAUTIONS

Your Ironworker uses hydraulic pressure and moving shear blades to cut steel products. To operate this tool safely, please review the following safety precautions.

Read and understand your Ironworker Operator Manual, Installation Manual, Machine Safety Manual and Maintenance Manual.
Use the tool ONLY for its intended operation.
Wear approved eye protection.
Wear protective gloves and clothing.
Use safety guards, material hold-downs and punch stripper supplied with your Ironworker. Removal, modification or improper use of these safety devices may result in serious injury and will void your machine warranty.
Keep away from moving parts during operation.
Always be ready to lift your foot off the foot pedal to stop a mistake from seriously injuring you.
Unplug or lock-out/tag-out your Ironworker before performing and maintenance or adjustment activities.
Any maintenance, adjustment or changes in tooling for your Ironworker must be performed by a qualified individual with the processes and procedures describes in the Operator Manual.
Maintain a clean machine. Remove any obstructions, slugs, cut-offs and fillings from the work area.
Adequately support the steel material being worked.
Turn your Ironworker off when not in use-never leave a powered Ironworker unattended.

MACHINE SETUP

Your Ironworker was bagged, palletized, and shipped from the factory to your dock. Remove the protective packaging and bolts from the tubular legs that secure the machine to its pallet. Move your Ironworker to its fabrication location by inserting your forklift forks within the tubular Ironworker legs. Do not move the machine by any other means! Locate your Ironworker directly adjacent to your power supply. See instructions for elctrical hookup written down below.

CARE AND PERIODIC MAINTENANCE
Your Edwards Ironworker will benefit from reasonable care and periodic maintenance.

Provide clean ISO Viscosity 46 hydraulic fluid (or equal) to the cylinder in the Ironworker. Contaminated fluid will compromise your cutting operation.
Grease all machine guides and pins daily. Your Ironworker is labeled with all grease locations that require maintenance.
Maintain .010 clearance between fixed and movable shear blades on 40, 50, 55, 60 and 65 Ton models at all times. Maintain .015 clearance between fixed and movable shear blades on 75, 100, 100D and 120 Ton models at all times. Insert a feeler gauge between fixed and movable blades to verify proper blade clearance and shear tolerance. Adjust tolerance of shear blades by relieving the locking nuts that secure the gib-pins to the Ironworker frame. Once loose, rotate gib-pins to push the operating center against the frame. Gap the angle and bar shear blades with the specified clearance and tighten the gib-pin lock nuts. Failure to maintain proper clearance will result in lower quality cuts, damage to blade, blade pockets and potential to damage the Ironworker frame.
Periodically check gib-pins for lubrication and snugness to operating center. Tighten gib-pins and locking nuts to maintain blade clearance as indicated above. Gib-pins are wearing parts. Order replacement gib-pins through your Edwards Distributor or through Edwards Mfg.Co.
The blade set for your Ironworker is crafted from S7, heat treated steel. These are wearing parts that will fail over time. Order additional blade sets through your Edwards Distributor or through Edwards Mfg. Co.
Check the hydraulic fluid level regularly. Replace the external oil filter on your Ironworker after your first 30 hours of use and every 1000 hours thereafter. Change your hydraulic oil every 5000 hours.
Periodically clean your Ironworker with a compressed air nozzle and soft cloth. Remove filings, dirt, dust and grime from working surfaces.
Periodically check tooling for wear. Replace worn tooling* according to manufacturers literature. If in doubt, call Edwards for advice.

Punching Assembly

PUNCHING

Your Ironworker is capable of punching materials as listed in the Ironworker Specifications section of this Manual as well as described on the capacity labels positioned at the Punch Station. The punch station on the Edwards Ironworker allows for a wide variety of punching, stamping or embossing applications. The removable table allows for flange or leg down punching of standard channel and angle sections.

Setup
Your Edwards Ironworker has been shipped with a punch and die installed within the punch station. When changing the punch and dies its important to make sure the machine is turned off. Failure to power down your machine could result in injury to the operator performing the work. To setup your punch station, please observe the following steps.
1. Swing the Punch Stripper up from the punch by loosening the stripper assembly bolts.
2. Remove punch by loosening the punch nut assembly with factory supplied wrench.
3. Remove die by loosening the set screw at the front edge of the punch table and then lifting die from the die holder. If the die resists removal gently tap the die from the underside of the punch table to loosen the die for removal.
4. Install new die and tighten set screw. If loading a shaped die, align the whistle spot with the set screw and tighten.
5. Install new punch and tighten punch nut with wrench. If using a shaped punch, align the locating keystock of the punch with the corresponding slot within the punch stem assembly and tighten the punch nut with the wrench.
6. Check for punch and die alignment by powering up the machine and inching down the punch to meet the die with the foot pedal. Check to see that the punch is centered in the die.
7. In the event that the punch and die are not aligned, loosen the bolts under the table allowing the table to be moved to center the die. When aligned, tighten the table bolts to secure the table.
8. Swing the stripper bar back in place allowing for minimal clearance between the top of the material and the bottom of the stripper and tighten the stripper bolts.

Punch Operation
When familiar with the setup and safe operation of the punch station, clear the punch station of any tools or debris prior to powering the machine on. When clear, power the machine on and place the material to be punched between the punch and die. Check to see that your material is spanning the stripper plate and that adequate material is available beyond the stripper area to safely position the material. Clear your hands from the working area and depress the foot pedal to move the punch through the material and into the die. When the punch is complete, release the foot pedal automatically strip the material from the punch and return the punch to its neutral position.

Recommended Punch and Die Operating Clearances

Material Thickness Total Clearance in inches
16 gauge and lighter .006"
15 gauge - 12 gauge .010"
3/32" - 5/32" 1/64"
3/16" - 15/32" 1/32" (standard unless specified)
" and heavier 1/16"

Punching Capacities
You can determine the tonnage required to punch A36 mild steel (yield strength 32,300 psi, 65,000 psi tensile) by applying the following formulas for round or shaped holes. For materials other than mild steel please refer to the multiplier table.
Round Holes:
Punch Diameter x Material Thickness x 80 = Tons of pressure required
Example:
How many tons of force do I need to punch a 3/8" hole in " mild steel?
.375 x .25 x 80=7.5 tons
Shaped Holes:
1/3 Punch Perimeter x Material Thickness x 80= Tons of pressure required
Example:
How much force do I need to punch a 3/8" x 1" rectangular hole in " mild steel?
(.33 x 2.75) x .25 x 80=18.2 tons
Click for Chart for Tonnage to Punch a Hole

Material Multiplier
When punching materials other than mild steel first calculate tonnage as shown above then apply the multiplier for the listed material.
Material Multiplier
Aluminum: 0.38
Brass (1/4 hard): 0.70
Copper (1/2 hard): 0.52
Steel (50% carbon): 1.50
Steel (cold rolled): 1.24

Important Hole Punching Recommendations:
* Punches normally get dull faster than the die so if you are planning to punch many holes it would be wise to order extra punches at a ratio of about 3 punches for 2 dies.
* Punching holes in stainless steel will dull your punches extra fast. It helps if you spray some cutting oil on the spot before you punch the hole.
* Punching holes in type A36 steel can be unpredictable because A36 is made with recycled steel. The A36 that was made when the steel mill was recycling sheet metal is easier to work with than the A36 that was made when the steel mill was recycling ball bearings.
* For repeat punching in the same position it is recommended that you add a Gaging Table to your machine so you can accurately position your workpiece where you want it over and over again with little effort.
* If you a planning on punching hole patterns with holes that are less than 4 inches apart then you should consider buying a custom made multi-punch and die set that can punch multiple holes simultaneously perfectly spaced everytime. You will need the extra large 241 or 48XX type of punching assembly to do this.
* If you are planning on punching holes for wrought iron fencing or some other reason that requires holes to be evenly spaced on many pieces, then you should consider a CNC feed system.
* If you are punching holes in copper or soft aluminum or very thin steel then you should consider buying a Urethane Stripper to hold the metal down firmly while punching for a nice distortion free hole.
* If you are puching holes in thin metal you should consider using the stroke control to save time on the up and down cycle.

IMPORTANT MAINTANENCE FOR YOUR HYDRAULIC IRONWORKER MACHINE
1. Grease your machine minimum of once for every 8 hours of use. This is the most important thing you can do to make your machine last a long time.
2. Change your hydraulic oil a few months after you get your machine to get the break-in oil out of the machine. If you cant change the oil regularly, please change it at least once. It will make a big difference. Heavily used machines should have their oil changed at least once per year. Your hydraulic cylinder, hydraulic pump and hydraulic valve will appreciate it. Edwards recommends using viscosity 46 hydraulic oil.
3. Change your punches and blades when they get dull to prevent from overloading the machine.
4. Make sure you are using your machine on level ground to prevent overloading one side.
