In this manual particular references are made regarding aspects of safety and the notes below
are intended as a summary to highlight the main areas for your attention.
The machine should be positioned so that the operator has sufficient room to work having
regard for the long lengths of material which may be punched or cropped. Electrical supply
should be by overhead cable to avoid possible damage.
It should be considered if additional equipment will be required to safely handle long or heavy
items being processed.
Any person who will use the machine should be given adequate instruction on the operation
and safety aspects of the machine. Extra copies of this manual are available from the
manufacturer.
In addition it should be established which persons shall be responsible for the changing and
setting of tools and blades and these persons given a more detailed instruction.
Mubea Systeme machines are supplied complete with various guards and barriers as standard
equipment which provide a generally accepted level of guarding when the machine is used for
the purpose for which it was designed.
1. The main areas of deviation from design criteria would probably be:
2. The use of materials other than mild steel (65.000lbs.)
3. The incorrect use of material hold-downs
4. The punching, cropping or notching of small items
(as this would encourage the operator place fingers or hands into danger area).
If at any time additional tooling or equipment is fitted to the machine the question of adequate
guarding must be reviewed and the advice of the manufacturer sought if necessary.
All maintenance should be carried out by suitably qualified personnel and particular attention
must be paid to the correct setting and alignment of punches and dies, blades and other tools.

3.6.1 System Pressure
To check any operational loadings, a pressure gauge can be fitted at the manifold position.
The max. system pressure has been set at the works to 234 bar (3500 P. S. I.) which is below
the max. continuous working pressure of the pump, thereby giving increased reliability.
3.6.2 Cleaning
On arrival, all anti-corrosion lacquer should be removed from the machined bright parts with
petroleum solvent. When the machine is operational, all visible working parts should be
regularly cleaned of foreign matter, thus preventing excessive wear and possible failure.
3.6.3 Lifting
The machine is supplied with a lifting eye, mounted on top of the machine. All lifting and
manoeuvring should be carried out using this eye along with a suitably rated chain or sling.
The eye can be removed if desired after final siting of the machine but hole should be blanked
off.
DO NOT USE SLINGS UNDER MACHINE!
3.6.4 Installing
Locate the machine on a solid foundation allowing sufficient area all round for easy working
and maintenance. The machine may be used free standing, but bolting to the foundation is
recommended. With the machine mounted directly on the floor - this gives a comfortable
working height.
3.6.5 Electrical Supply
Input wires should arrive at the machine via suitably protected underground supply directly
into the electrics box in the base of the machine. As an alternative by overhead supply to the
top of the machine and routed inside the top guard and hydraulic pipe trunking to the electrics
box. A 30 amp isolating switch, fuse and appropriate cable should be used for mains supply
connection. The circuit provides protection against sustained over-load and phase failure.
Should the machine cut out during an operation or whilst running, the cause of the problem
should be investigated to prevent re-occurrence.
IMPORTANT
Motor rotation MUST be as arrow on motor fan end cover!
This machine will not operate if the motor is running in the wrong direction. It must be
stressed however that the motor must not be allowed to run in the wrong direction for
more than a few seconds, as this will cause seizure of the pump. To check motor
direction start and stop motor with foot on footswitch if machine does not operate
reverse two of the incoming 3 phase connections.

The Operating Mode Switch has two positions - NORMAL and INCH. With
the switch set to INCH all work stations are in the slow speed Inching Mode.
3.10.1 Inching Positon
In Inching position the arm will travel down slowly when footswitch is fully depressed. The
arm will remain in any position when foot is removed. Turn switch to NORMAL to return
arm to top of stroke. All tool setting and adjusting and setting of stroke limit switches should
be done in the Inching position.
3.10.2 Normal Operating
With Selector Switch to NORMAL the arm will travel down at operating speed when
footswitch is fully depressed and will return to top of stroke when foot is completely removed.
The footswitch does however have three “positions” giving the very useful facility that after
bringing the arm down by full depression of switch, the arm may be held in any position of the
stroke by raising the foot to the mid-position. Remove foot and arm will return to top position.
3.10.3 Punch and Die Alignment
Should be checked before using, and MUST be checked after punch and die changes have
been made.
To check alignment switch mode of operation INCH, then inch the punch
down by fully depressing the footswitch. Care must be taken as the punch
approaches the die, if misalignment is apparent remove foot from switch.
To align punch and die release bolster fixing screws, operate the foot switch with care,
aligning the bolster containing the die to the punch, the punch will stay in the down position.
Centralise the die clearance around the punch, clamp the bolster in position, tighten die
retaining screw, check die maintains in the central position after clamping. Return punch to
top position by switching back to run position.

The punch station is a particular well equipped station. It offers many features normally
associated with much larger machines.
The large punch bed area is designed to give a very wide range of punching applications,
including overhang work in small channel sections. The punch table is particularly useful
when the side and back stops are set for small repetetive work. This coupled with a finely
adjusted stroke length gives a very productive machine. The table is assembled in two parts of
which the front is removable for flange punching.
The punch is retained by means of a quick-change device. Changes are quikly and without
problem and require no additional devices. The die is retained in the bolster by a set screw,
ensure the screw locates correctly on the machined flat on the die when shaped punches and
dies are being aligned.
The punch stripper plate must be correctly adjusted allowing sufficient clearance for placing
and removal of material, but must NOT restrict the punch stroke, ensure the bottom stroke
limit switch is correctly adjusted. Punch holes with sufficient material around the hole so that
contact will be made on both sides of the stripper plate. Stripping forces can be severe and
unbalanced stripping forces, due to contact on one side stripper, may cause punch breakages.
When using stripper fingers for oversize holes or irregular shapes position and adjust fingers
equally so as to avoid unbalanced stripping loads.
Additional tooling in this versatile work station can provide bar bending, corner notching,
tube notching and general die-set work.
WHEN ORDERING REPLACEMENT PUNCHES AND DIES, ALWAYS
QUOTE - MODEL, TYPE AND SERIAL NUMBER OF MACHINE.

1. The punch stripper plate must be adjusted correctly with sufficient clearance to allow
positioning and removal of the material being punched.
2. Punch holes with sufficient material around the hole so contact is made on both sides of the
stripper plate. Stripping forces can be severe. Unbalanced stripping forces may cause punch
breakage.
3. Liberal oiling of the punch will considerably lengthen the life of the punch and die and also
help reduce the stripping forces.
4. The quality of the hole (or blank) is an immediate indication of the condition of the punch
and die.
5. Do not punch material thicker than the punch diameter, this overloads the punch and can
result in breakage.
6. Punch full and complete holes, do not punch partial holes unless tooling is specifically
designed to do so.
7. When punching small items (i.e. small pieces of plate, bar etc) these items MUST be places
and extracted with suitable handling aids, extra guarding may be required too ensure
operator safety.
8. Stay within the rated capacity of the machine.

Die clearance: It is normal practice to aim for a clearance of 10% material thickness.
Whether clearance is added to the size of the die or deducted from the size of the punch,
depends on the nature of the work. When holes of a given size are required the punch is made
to size and the die is made larger. Conversely, when blanks of a given size are required the die
is made to size and the punch smaller.
Special clearance dies for thin sheet and plate punching, or size dies and special clearance
punches can be supplied to order.

The graph shows the punch capacity curves for the BULLDOG 65 and BULLDOG 50
machines. As an example it can be seen to punch material 15mm ( 5/8 ’’) thick, the maximum
diameter is 22mm ( 7/8 ’’) on the BULLDOG 50 and the maximum diameter on the BULLDOG
65 is 28mm (1 1/16 ). As an alternative it is possible to calculate a capacity by using the machine
constant. By dividing the machine constant by the material thickness will give the maximum
diameter through that thickness.

If you want to calculate the max. Material thickness / max. hole sizes use one of the following
formulars:
Constants / Material Thickness = max. Diameter
or:
Constants / Diameter = Max. Material Thickness
Note:

BULLDOG 65 Hydraulic Steelworker

All capacities are based on materials to be punched having a tensile strength of 45 kg/mm²
(65.000lbs). Always keep within the rated capacity of the machine and never attempt to punch
a hole smaller in diameter than the thickness of material being punched.

BULLDOG 65 Hydraulic Steelworker

1. Example:
You are going to work with a material of 10mm ( 3/8 ’’) thickness on a BULLDOG 65 machine.
The max. hole size is then calculated by:
420 / 10 = 42 [mm] ⇒The max. hole size is 42mm (1 5/8 ’’).
2. Example:
Your punch / die diameter is 26mm (1’’).
The max. material thickness you can punch is calculated by:
420 / 26 = 15,4 [mm] ⇒The max. material thickness is 15mm ( 3/5 ’’).
This system will proably prove to be convenient because when the machine capacity constant
has been memorised, no tables or graphs are required to establish max. diameters through a
known thickness of meterial.
Please Note: DANGEROUS PRACTICE:
DO NOT ATTEMPT TO PUNCH MATERIAL
THICKER THAN THE PUNCH DIAMETER!

IMPORTANT NOTICE - HEALTH & SAFETY AT WORK ACT, SECTION 6
Bending tools must not be fitted to this machine until adequate safety measures have been
implemented. It is normally permitted to use the bending tools without additional fixed
guarding provided the following steps have been taken:
1. The clearance between the top tool and the work piece is kept to a minimum and must not
exceed 6mm at any time.
2. The bending tool is set by a skilled and competent person.
3. A lockable cover has been fitted to prevent unauthorised alteration of limit switch.
The key should be retained by the setter.
Bending Tools are supplied with suitable cover and lock as standard.
