switch to select between punching, shearing or notching operations. In
PUNCH and SHEAR mode, the slide travels in full distance set by the
upper and lower stroke limit switches. In the NOTCH mode, the slide
travels at a shorter distance set by middle and lower stroke limit switches.

Note:

The PUNCH/SHEAR/NOTCH switch is electrically interlocked with
the Notch Safety Guard. When in PUNCH and SHEAR mode, the machine
is IMMOBILIZED if the Notch Safety Guard is lifted. Please also refer to
the section on stroke adjustment.

Note for IW-60H only:

square/round bar shear station, the operation of the bar shear station on IW­60H is in the same selection as the punching operation. In other words,

PUNCH/SHEAR Switch

(for IW-45M) - Use this switch to select punch or

shearing operations.

NORMAL/JOG Switch

- This switch allows selection between the normal
(automatic return) mode and the jog (low pressure, slow speed, non- return)
mode. Use the normal mode to operate the machine. Use the jog mode to
align punch/die, to set blade clearance, and to set the strokes. In NORMAL
mode, the ram/slide move in both up and down directions. In JOG mode,
the hydraulic system is in low pressure setting and the ram/slide move only
in downward direction at slower speed. Also refer to the section on Low
Pressure Tool Alignment in JOG mode.

AUTO/MANUAL Switch

(for machines equipped with the optional
electric backgauge only) - Turn to AUTO to use the backgauge, and turn to
MANUAL to use the foot switch. Also refer to the section on electric
backgauge.

IMPORTANT WARNING:

On IW-45M, IW-50A, and IW-60H models, in PUNCH mode the
cylinder/slide moves in opposite direction as to the SHEAR/NOTCH mode.
Therefore, when switching from Shear or Notch mode to PUNCH mode, the
cylinder starts moving and the Shear/Notch Blades will come down.
Similarly when switching from Punch mode to SHEAR or NOTCH mode,
the cylinder starts moving and the Punch will come down.

This has the
potential of body injury. Before turning the PUNCH/SHEAR/NOTCH
switch, be very careful and make sure that the punching stripper and
notcher cover are closed, that no materials are in any of the
workstations, and that all fingers and body parts are away from all
moving parts. ONLY for the supervisor and his trained authorized
operator of the machine who understands the potential risk of the
machine and is authorized to use the notching station.

Low pressure tool alignment with JOG mode

Sunrise Fluid Power Inc. is the market leader in providing low pressure tool
alignment setting on its products. When the NORMAL/JOG switch is
turned to JOG mode, the machine provides a low pressure and low speed
setting for safer tool alignment operation. This will reduce tool damages
due to miss-alignment of tools and increase the operator safety. If a
material is placed under the punch in JOG mode, the punch will only make
a dent on the material without punching through. In addition, the punch
cylinder will only move downward when the foot paddle is pressed, and
will not retract backup when the foot paddle is released. Turn the
NORMAL/JOG switch to NORMAL to move the cylinder upward.

The JOG mode works for all working stations. The safety cover of other
stations MUST be closed for the machine to move.

WARNING: for ease of tool alignment, the stripper cover is allowed to
open in JOG mode. Even with the low pressure setting, be sure to keep
all body parts away from moving parts, wear appropriate eye
protection goggles and gloves for eye and hand protection. The JOG
mode is a keyed switch, and only properly trained and authorized
personnel should have access to the key and use the machine with JOG
mode.

FOOT SWITCH

The machine uses a foot switch for easy and fast operation control. The
foot switch enables the operator to use the machine while holding the work
piece with both hands. NEVER has one operator hold the material and
another operator press the foot switch.

The foot switch has three positions: UP, HALFWAY and DOWN.
UP position is when you release the foot switch completely.
HALFWAY position is when you press or release the foot switch halfway.
DOWN position is when you press the foot switch all the way down. When
not pressed, an internal spring pushes the switch to the UP position. The
foot switch functions differently in the NORMAL and the JOG modes.

In NORMAL mode

downward motion of the slide. Release the foot switch to HALFWAY
position will cause the slide to stop. This is very useful in position the work
piece without using the gauge stoppers. Press the foot switch again to
Down position and the slide will continue moving downward until reaching
the lowest position set by the limit switches. Releasing the foot switch
completely (UP position) will cause the slide to return to its up position.

In JOG mode

, press the foot switch to the DOWN position for the
downward motion of the slide. The slide stops moving when the foot
switch is released to either HALFWAY position or UP position. The slide
does not move back up even when foot switch is completely released. This
allows the operator to make necessary adjustment / alignment. In other
words, the slide moves only in one direction in JOG mode. To move the
slide back to the up position, switch the Normal/Jog switch to NORMAL.

ELECTRIC BACKGAUGE

Optional electric touch-and-cut back gauge is available to control the
movement of the machine (instead of using the foot paddle). To use the
electric back gauge, turn the Auto/Manual switch to AUTO. To use the
foot switch, turn the switch to MANUAL.

To use the electric backgauge:

1) Install the two pipes of the backgauge.

2) Connect the sensor wire to the socket on the back of the machine with

the key way correctly aligned.

3) Turn the switch to AUTO.

4) Adjust the back gauge to the desired length.

5) Position the sensor on the back gauge so that the working piece will

touch the sensor during operation.

6) To operate, simply push in the work piece. When the sensor is touched

by the work piece, the blade will start moving down after a short delay.
The delayed time can be adjusted by a timer inside the electrical box.
After the shear, the cut piece falls out and the blade automatically
returns to the up position for the next shear.

7) If the length of the sheared piece is not the same as the reading on the

backgauge, there is an adjustment nut on the backgauge to set the zero­position of the backgauge reading.

NOTE:

the machine will complete the whole shearing cycle

be stopped halfway unless the emergency stop button is pushed. Although
the electric backgauge increases the working efficiency, special care is
required when using this function. Carelessness often causes accidents.

STROKE ADJUSTMENT

Certain working operations do not require a full working stroke. For large
quantities of the same operation, merely execute the required working
stroke distance to save operating time. The position and length of the
cylinder strokes are controlled by adjusting the limit switches and actuators
on a drive bar installed on the back of machine.

For IW-45M:

There are two limit switches, one for the upper limit and one for the lower
limit. The role of the limit switches changes from Shear mode to Punch
mode. In other words, the upper limit in Shear mode becomes the lower
limit when switched to Punch mode, and vise versa.

For IW-50A and IW-60H

There are three limit switches, one for the upper limit, one for the lower limit,
and one for the notch upper limit (short stroke). At SHEAR and PUNCH
mode, the slide moves in full length between the right limit switch and the
left limit switch. The role of the limit switches changes from Shear mode to
Punch mode. In other words, the upper limit in Shear mode becomes the
lower limit when switched to Punch mode, and vise versa. In NOTCH mode,
the center limit switch functions as the upper limit (short stroke), and the
slide moves between the center and left limit switches.

Note: the center actuator for the center limit switch must be adjusted to stay
at the left side of the limit switch. This enables the stroke movement
between the center and left limit switch in the Notch mode. Fail to do so
will result in the machine not function properly.

IMPORTANT:

The limit switch must be actuated before the Cylinder
reaches the full extend or full extract position. In other words, the pump
should be unloaded in upper or lower limit of the slide travel.

ADJUST THE MAIN CENTRAL SLIDE

The main central slide (holding the moving shear/notch blades) should be
pushed against the back of the machine body. Adjustment of the central
slide is carried out by setting the "Pressure Pads". These pads are located
on the front body of the machine. They can easily be identified as each has
a grease nipple (same location as the grease points). To adjust, loosen the
locking nuts, then tighten the screws firmly. Then, loosen each screw

third of a turn.

Lastly lock in position by tighten the locking nuts. Repeat

one

the procedure for each of the pressure pads.

ADJUST THE PUNCH RAM (IW-50A Only)

The alignment of the punch ram is guided by a "guide pad" inside the ram
holder. When the ram is loose and starts to swivel or when the ram is
misaligned (not square with the die base), the punch ram should be adjusted.

To adjust the punch ram, follow these steps:

1) Take off the warning plate in front of the punch ram.

2) Take out the two screws found underneath the warning plate and then

the adjusting screws will be exposed.

3) Adjust the adjusting screws to press the guide pad uniformly on the ram.

Do not over adjust the guide pad.

4) Check the adjustment by moving the ram up and down with non-round

(oblong or square) punches and dies. The ram should be moving
smoothly and without any swivel gaps.

5) Screw back the two outside screws to prevent loosening

6) Put back the warning plate.

Many other punching tools of different sizes are also available upon request.
In addition, a large 2-piece support table with gauges is installed as standard
equipment.

IMPORTANT:

operation. On some models with an interlock limit switch inside the
stripper back cover, the punching station is IMMOBILIZED if the stripper
is open.

Alignment of Punch and Die

The punch and the die may have previously been centered. However, you
should check the tools regularly for proper alignment. To center the die,
follow these steps:

1) Insert Punch into Retaining Nut, then tighten the nut onto the Retaining

Thread.

2) Insert the Die into the Holder and secure the set screw.

3) Loosen all of the die holder fixing bolts

4) Lower the punch gradually (by using the JOG mode).

WARNING: Be very careful that the punch does not hit the die

which can break the punch and create a hazard.

5) After the punch is inside the die, turn power off and isolate the machine.

6) Adjust the position of the Die Holder until the Clearance around the

punch and die is even all the way around.

7) Tighten the die holder bolts to fix the die position.

8) Adjust the limit switches to change the stroke length if necessary.

When setting up square or oblong punches and dies, be sure to properly
locate the key on top of the punch in the keyway of the punch retaining
thread. Check carefully the alignment (both position and direction) of the
die with the punch. Incorrect set up will damage the punch and die, and
may cause danger.

The punch stripper must be closed properly during

IMPORTANT:

Be sure to check the alignment of the punch and die
whenever tools are changed.

Punch and Die Clearance

Punch size is the same as the desired hole size. Die size is bigger by the
clearance. The clearance depends on the thickness of the material. The
clearance is usually about 10% of the material thickness. Please also refer
to the following chart for recommend clearance.

Material Thickness mm up to 4 4 - 9 9 – 14 14 - 20
Die Clearance mm 0.2 0.7 1.2 1.7

Adjusting Stripper

The distance between the stripper and the material should be adjusted to

z

about 2~3mm. Adjust the stripper height each time when changing to
material of different thickness.
Adjust the stripper height by turning the large knurled screws at both

z

sides of the stripper.
If the stripper tend to fall down at the right side, tighten the spring at the

z

left side of stripper.
Make sure the stripper is at even height for left and right sides. The

z

stripper should be adjusted so that the work-piece contact the stripper
evenly when the punch retracts out of the material. Unbalanced
stripping may break the punch and cause hazard.
If the material cannot have adequate contact with the stripper when

z

stripping, such as asymmetrical material, material too small, or punched
hole too close to the edge of material, do not proceed with the punching
operation.

The stripper has exchangeable plates with various opening sizes to match
the size of the hole. Select the plate with the smallest suitable opening.
Keeping the opening close to the size of punch will greatly reduce
deformation, especially on thinner materials.

Actual Punching Force

The actual force required in a punching operation is calculated by the
circumference of the hole multiplied by the thickness of material multiplied
by tensile strength of material.

Max. Capacity = circumference x thickness x tensile strength

2

The capacity chart is based on material with 45 kg/mm

tensile. Do not
attempt a punching operation that requires force over the maximum
capacity of the machine.

Precaution

1) Always use die with the proper clearance.

2) Always check the alignment after each tool change.

3) To prevent overloading and breakage of the punch, do not punch

material which is thicker than the hole diameter,

4) Do not punch partial holes. Punching incomplete holes will cause the

punch and die to bend and break.

5) Applying some lubricant oil on the punch will prolong the life of the

punch and reduce the stripping load.

6) Regrinding of punching tools is not recommended.

FLAT BAR SHEAR STATION

This station is equipped with a hold down suitable for shearing of various
material thickness. The machine also comes with a feed table with guides
for material support and positioning. Besides shearing flat bars, this station
can also shear the flange of angles.

Blades

Upper Blade (Moving): The moving shearing blade has a special curved
cutting edge to minimize distortion on the shearing cuts. The moving
blade can be turned to utilize both cutting edges.

Lower Blade (Stationary): The stationary blade can be turned for the use of
all four cutting edges to provide a long blade life.

Cutting Clearance

The width of the cutting clearance (the distance between the moving and
stationary blades) had been pre-adjusted in the factory to be between 0.2
and 0.3mm. The cutting clearance depends on the thickness and tensile
strength of the material. The thicker the material, the wider the cutting
clearance should be. Improper cutting clearance can result in the
deformation of the working piece. Too large of clearance when shearing
thin material can cause the material to bend over instead of being sheared.

The cutting clearance can be adjusted by the fix bolts that "pull in" the
stationary blade and the adjusting screws that "push out" the stationary
blade. To adjust clearance, follow these steps:

1) In JOG mode, move down the top blade to the lower position so that
the opening between blades are closed.

2) Turn power OFF and isolate the machine.

3) Remove the holddown and the feed table.

4) Loosen the large fixing bolts that holds the lower blade.

5) Loosen the locking nuts on the adjust screws.

6) Adjust the clearance by turning the adjusting screws which push the
lower blade towards the upper blade.

7) Check clearance using a feeler gauge.

sure that the cutting clearance is uniform for the entire blade.

It is very important to make

8) Tighten the locking nut of the adjust screws to prevent loosening.

9) Tighten the fixing bolts to fix the position of lower blade.

10) Reinstall the table and holddown.

11) Check clearance again to ensure even clearance.

Precaution

1)

Do not shear any piece too small to be secured in position by the

holddown. Doing so can seriously damage the machine beyond
repair. See Figure

.

2) Always feed cutting material from front. NEVER insert material from

back.

3) Keep the cutting edges sharp. Check the sheared material to see whether

the cutting clearance is properly set and that the condition of the blades
are O.K.

4) Clean the scraps and waste materials regularly and keep the work area

clean.

ANGLE SHEAR STATION

This working station can do 90-degree shear on Angles as well as 45-degree
internal miter shear. On IW-60H, external miter shear is also possible.
Feed the material through the central slot on the hold-down for 90-degree
shear. On IW-45M and IW-50A, feed the material through the slots on the
top and side of the hold-down for different directions of 45-degree internal
shear. On IW-60H, feed the material through the two slots on the hold­down for internal and external 45-degree shear.

At 45-degree miter shear, the blades cut both flanges of the angle. So when
matching two angles to make a turning joint, the gap between the vertical
flanges is at minimum.

Blades

Stationary Blades: The two stationary blades each has 4 cutting edges.
Turn the blades to use the other cutting edges.

Moving Blade: The moving blade also has 4 cutting edges. Turn the blade
diagonally to use the other cutting edges. To avoid the blade making a
mark on the material, the tip of moving blade can be grounded to match the
inside radius of the angle steel.

NOTE: On the IW-60H, there are total of 4 blades for this station, one large,
one small moving blade, and one large, one small stationary blade.

Keep the blades clean. Remove all small slugs and other waste material.
Do not allow mill scale to build up in the blade area.

Cutting Clearance

The clearance between the moving blade and the stationary blades were pre­adjusted to be between 0.2mm and 0.3mm. The cutting clearance can be
adjusted by the fix bolts that "pull in" the stationary blades and the
adjusting screws that "push out" the stationary blades. To adjust the
clearance, follow the following steps:
