PRINCIPALS OF OPERATION

The Hougen-Ogura Electro-hydraulic Hole Puncher is an integrated unit, containing the electric motor, hydraulic pump, and "C"-frame punching unit. It uses hydraulic power to force the punch through the workpiece, and a strong spring to return the punch piston to its "home" position. The patented design includes an automatic valve that releases the hydraulic pressure when the punch piston is at the bottom of its stroke. The automatic valve remains open until the punch piston has fully returned to the home position. As a result of this design, the piston will not return to its home position automatically unless the full stroke has been completed.

Also, the punch will not begin another stroke unless the punch has fully returned to the home position, resetting the automatic valve.

In the event that the punch does stick in the material, keeping the punch piston from returning to the home position, the

75004PR now features a power return. Leaving the manual return valve closed and depressing the trigger, the punch piston will now be powered back to the home position.

To allow the punch piston to be manually returned in the event that the punch cycle is stopped prior to completion, a manual return valve is provided.

FOOT SWITCH

Although the foot switch is guarded against inadvertent operation, it is best to position the foot pedal away from normal standing position. Place it in a position that requires deliberate effort to reach and activate the switch.

The trigger switch should be locked on only when ready to punch. Release the trigger switch immediately after punching to prevent operation by inadvertent actuation of the foot switch.

HOLE LOCATOR GAUGE ADJUSTMENT

The Hole locator Gauge can be set to hold the Hole

Punches at a constant distance from the edge of the workpiece. The gauge is held in place by one or two socket head caps screws. Before making any adjustment, first, unplug the power cord. To adjust the position of the gauge, loosen the cap screw(s), tap the gauge into the desired position and retighten the cap screw(s).

USING THE WORK STAND

All models can be used with an accessory work stand for

bench or table mounting of the Hole Puncher. The stand

is standard with all models. To install the stand, first

unplug the power cord., then mount the unit to the stand

with the supplied hardware.

When using the stand, periodically check to make sure that the punched material (slugs) are not stacking up between the exit hole in the "C"-frame and the stand.

Keep this area clear of accumulated slugs.

TRIGGER SWITCH

Pull the trigger switch for punching operation. Make sure that the switch is fully depressed. DO NOT ride the switch as this will harm the motor.

The lock button is used to lock the trigger switch “on” when using the foot switch. Pull the trigger switch and push in the lock button. To unloc, push in the lock button again.

SLIDE STOPPER

Punching up to 40mm depth, from the edge of material, can be done using the slide stopper.

CAUTION

Before attaching or removing slide stopper, ensure that the machine is disconnected from its power source to prevent accidental operation and personal injury.

1. Loosen the set bolt and nut to remove the Die.

2. Remove the bolt and washer fixing the slide stopper.

3. Remove the slide stopper by pulling it to the upper side of the C frame.

4. Insert the slide stopper for maximum depth from the

bottom side of the C frame.

5. Fix the slide stopper with the bolt and washer removed in procedure #2 above.

6. Install the die with the set bolt and nut removed in

procedure #1 above.

REMOVING AND INSTALLING ROUND PUNCHES

Prior to removing a punch, jog the punch piston down until it puts pressure on a piece of material that is of the appropriate thickness. With a pin spanner, loosen the retaining nut. Manually release the punch piston with the manual release valve, disconnect the unit from the power supply and then remove the retaining nut and punch.

Prior to installing a different punch, check for debris in the retaining nut and punch piston. Clean if necessary. Prior to installing a punch, verify the "O" ring on the punch piston is clean and not damaged.

Place your punch into the retaining nut, properly align the punch within the punch piston and hand tighten the retaining nut. Plug in power, jog the punch piston down until it makes contact with your work surface. Tighten the retaining nut with the pin spanner. Manually release the punch piston. Your now ready to punch your material. Failure to align your punch properly could result in serious damage to your machine. It is not necessary to remove your die to install the punch piston.

ROUND PUNCHES

CAUTION

Before replacing the punch and die, ensure that the machine is disconnected from its power source to prevent accidental operation and personal injury.

1. Be sure that the punch piston is fully retracted and remove the strippers to make access to the parts easier.

2. The punch must be removed first and then the die. Unscrew the punch retaining nut to remove the punch and remove the set bolt and the nut to remove the die.

Note: When replacing the punch and the die, make sure that the correct size, thickness and hole shape is seleted. Shaped punches and dies must be properly aligned with each other.

3. Place the punch in the punch retaining nut, then insert the punch with the nut into the punch piston and hand tighten the nut.

Note: When installing a punch with a stepped edge (anti rotation), make sure the orientation is correct and that the stepped edge is correctly positioned in the punch piston.

4. Make sure the punch is correctly positioned in the punch rod and tighten the punch retaining nut firmly with the Tommy Bar supplied.

5. Place the die in the C-frame in the proper orientation secure firmly with the set bolt and tighten the nut.

SELECTING PROPER DIES

Proper die selection is essential. Other than the obvious necessity of matching shaped punches and dies, there are two other basic selection factors that must be considered.

The first is die clearance. Different material types and different material thicknesses require different clearances between the punch and die. In order to maintain the best possible hole while remaining within the tonnage capacity of the machine, it is essential to choose the die with the proper clearance. The second is the die angle.

Most structural shapes can be punched with the standard flat dies, but "I" -beams and most channels which have a 2-in-12 taper require the use of special

9-1/2 degree angled dies. Car and ship channel flanges and other structural shapes with a 2 degree taper can be punched with flat dies. Materials with a flange taper of less than 5 degrees can also be punched with the flat die, however, the hole will be slightly angled. Refer to specific information and tables within this manual for the proper punch and die combination.

REMOVING THE NEW DIE

1. To make it easier, please remove the

strippers 3. Pull the die up to the tip of the punch

New Die Old Die

CAUTION WHEN SELECTING THE DIE

Material

It is important that the die selected is correct for the thickness of the material to be punched.

Punching material of thickness 4 mm to 8 mm using a die for thinner material can cause the punch to jam in the material. This is due to the smaller clearance betweenthe die and punch. In such a case the material will be pulled up by the retracting punch as shown in the drawing on the left. Special care should be taken when punching flat bar of mild steel, aluminum and copper.

OPERATING PROCEDURES

1. Before make any adjustment, turn off the power supply and unplug the power cord.

2. Check the position for punching and adjust the slide stopper to the required distance. The slide stopper, which is set to hold the hole puncher at a constant distance from the edge of the workpiece, is held in place by one or two socket head cap screws. Loosen the cap screw(s) and tap the slide stopper into the desired position. Retighten the cap screw(s).

3. Plug the power cord into a power outlet, ensuring that the voltage of the tool is the same as the supply.

4. Check that the return lever is fully closed in the clockwise direction.

5. Make sure that the punch piston is fully retracted.

6. Make sure that the proper punch and die are selected and that they are installed correctly.

7. Place the puncher in the require position on the work piece, using the slide stopper as a guide and lining up the point of the punch with the center mark of the hole to be punched.

8. Pull the trigger switch. The punch rod will extend and push the punch through the material. Keep the switch on until the punch has reached the end of its stroke and returns to its starting position. If the punch doesn’t return after punching finishes, release the switch to turn the motor off. Pull the switch again to run the motor and to return the punch.

(See further explanation below for procedure when punch becomes stuck in the material.)

To aid accurate and easy positioning of the punch, the switch can be operated on and off to jog the punch down to the work piece. If the position is not satisfactory, open the manual return lever to retract the punch for another attempt. If the punch doesn’t return to its starting position with manual return lever open, pull the trigger switch to return the punch.

When the punch fails to come out of the material after the punching:

1. Pull the trigger switch to run the motor and to return the punch to its

starting position by hydraulic power.

2. Release the switch, when the punch is fully returned to its starting position.

3. Proceed with the next punching operation according to the normal operating procedure.

When the punch fails to come out of the material after the punching or when it is necessary to stop the operation before punching is finished:

1. Turn the return lever counterclockwise until it hits the spring pin and

then immediatley back to its starting to release the internal pressure.

Note: If at this stage the punch retracts from the material under its own

power, allow the punch to completely return and then turn the return

lever back to its position. In this case it is not necessary to complete

the stages 2 and 3.

2. Pull the trigger switch to run the motor and to return the punch to its

starting position by hydraulic power.

3. Release the switch when the punch is fully returned to its starting

position.

4. Proceed with the next punching operation according to the normal

operating procedure.

Stripper

CAUTION WHEN USING THE STRIPPER

Material

Do not position the material with one end or both ends unsupported by the stripper. If the material is not properly supported, it will move when the punch tries to return causing the punch to jam and damage the tool.

9

MAINTENANCE

CAUTION

Keep the air hole at the end of the C frame clear of dirt and obstructions. The air hole has to be open in order to control the hydraulic pressure.

CAUTION

Do not undo or remove the three screws in the drawing on the left. Doing so will cause oil to leak from the tool.

ADDING OIL

Use of the correct hydraulic oil is essential. Approved oils are Shell "TELLUS Oil" and Exxon "TERESSTIC" (Part

No. 75376). Grade #46 viscosity must be used. Check the unit specifications. Make sure that the work area and all equipment are clean so that no dirt, dust or other foreign material can get into the hydraulic oil or pump area.

1. Locate the socket head cap screw that plugs the oil port.

It is just above the manual return lever on the right hand side of the Hole Puncher.

4. Carefully open the oil port by removing the socket

head cap screw.

5. Using the small squeeze bottle supplied with the

Hole Puncher, carefully add hydraulic oil to completely fill the reservoir. Rock the Hole Puncher back and forth slightly several times to free any trapped air bubbles, then add additional oil if necessary.

6. Replace the cap screw and wipe up any excess oil.

2. Lay the Hole Puncher on its left side so that the oil port is facing up.

3. Turn on the switch to move the punch piston almost to the bottom of its stroke. If necessary, cycle the punch several times to determine where the bottom of the stroke is, and to correctly position the punch piston.

In this position, the maximum amount of oil has been drawn from the pump and the correct fill can be obtained.

7. Cycle the Hole Puncher several times with the

Manual return Valve open, and again with the valve closed, to work any trapped air out of the system, then repeat the above procedure, making sure that the punch piston is almost at the bottom of the stroke before removing the cap screw from the oil port.

8. Add additional oil as necessary. If the unit was extremely low on oil, it may be necessary to repeat

the procedure several times.

CARBON BRUSH REPLACEMENT

When the carbon brushes become less than 6mm the motor force deteriorates because of low rectification. Carbon brushes need to be replaced.

1. Remove the carbon brush cap of the motor outer frame using a standard screwdriver.

2. Replace the carbon brushes with new ones.

3. Put back the caps.

HELPFUL HINTS FOR HOLE PUNCHING

Each of the punches is provided with a sharp point at its center. If the hole locations are center punched, the point on the end of the punch may be used to "find" the center punched spot.

Also, for accurate and easy positioning of the punch to a hole location, the switch can be intermittently pulsed on and off to jog the punch down to the work surface.

If the position is not satisfactory, open the manual return valve to retract the punch for another attempt. This operation can also be performed with the manual return valve "cracked" open slightly to prevent full punching pressure from being developed. In this manner, the punch can be easily brought right down to the surface without beginning to punch the hole. If the location is satisfactory, close the valve and finish the operation.
