All punching operating are processed by means of hydraulic power thus giving the machine
the ability to punch very efficiently and silently. It can either be used to punch thick materials
or thin materials in layers together. Punching is silent, powerful and efficient. The waste
materials in layers together. The punching table consists two parts. First is the punching
flange. The second is holder. The holder is a device that holds the material after punching not
to come back with the punch. It must be equally adjusted or it can break the punch. There are
different holders for different materials. However the standard holder which we supply is
suitable for punching is between 6-38 mm.

SAFETY PRECAUTIONS

All power and depth and other adjustment m ust be done under full control of an
experienced technician

SAFETY EXPLANATIONS

The Machine is equipped with a hydraulic check valve system in order to relieve the excess
pressure when the machine is overloaded, thus preventing serious damage to the machine and the worker. All safety precautions are for your safety, which we believe will be obeyed by our customers unasked.

SAFETY UNITS

Quick stop button use on the panel and main body Protective barriers
In this manual are summarized the important i nformation for work safety. The following
security explanations and instructions are considered as the essential information for your s afety. Any and all persons who must operate the machine should be firstly trained well in terms of the operation and safety information and instructions. For this purpose, more copies of this manual shall always be asked from the supplier. It should be clearly fixed out that which persons will have the responsibility to change and arrange tools and blades. These persons need to be essentially trai ned in terms of this subject.
All the METALLKRAFT machines are delivered as standard with a safety equipment, such equipment is for a high and general work safety. For this purpose, the machine should only be used in accordance for those purposes for which it has been constructed.

The most dangerous and probable deviations as to the construction limits of the machine are estimated to be as follows:

1.
Machining of other materials as unalloyed steel (45 kg/mm2)
2.
Erroneous use of the fixing installation
3.
Punching or fixing very small work pieces, as these will easily cause the operators be subject to danger zones.
Should the additional tools be necessary to be used on the machine, which are not foreseen by the producer, it should be re-verified whether or not there is sufficient safety and security against work accidents. For this purpose, the producer should be contacted for advice when deemed necessary. All the maintenance works should be carried out by sufficiently qualified expert personnel. Particular attention should be paid to the correct assembly and arrangement of the hole stamps, cutting cases, blades and other tools. In order to enable us and yourselves to fulfill our mutual and common responsibility for all people, we request you to read this manual very carefully before putting the machine into operation and to obey all the saf ety information and instructions.
Attention: All the parts of the machine dyed in r ed are danger zones and particular
attention should be paid in such zones!
All the operators should be instructed in order not to place their fingers or other body parts near, in or under the parts of the machine colored in red. There is the risk of losing the body parts when these are placed in such zones!
- 13
All the safety components and fixing installations that should be removed for maintenance purposes, should be remounted again before the machine is reoperated. The operators should wear the clothing described by the employer. The producer recommend the use of protection eyeglasses against eventual stamp breaks and shoes with steel covering in order to prevent foot of the operator against falling materials.

SAFETY RULES

1.
The assembly and adjustment works, tool changes and maintenance services shall only be realized by the technical personnel qualified for this purpose, who should strictly obey the instructions of the producer.
2.
Remove any oil remaining, cuttings and other impurities from the working zone where such remaining might be left the previous operator.
3.
Before the starts working on the machine, the operator should make sure that all the tools are in a perfect condition.
4.
Any leakage and order of hole stamps and cutting cases, blade tolerances etc. should be checked after each tool change and be readjusted i f necessary.
5.
The scraper should always be adjusted according to the material resistance to be machined. Unequal scraping forces can easily result with t ool breaks.
6.
Never punch any material which stronger than the diameter of the hole stamp. In this case, the hole stamp can be overloaded and easily break.
7.
Always punch trough holes. Never punch base holes, unless the tool is clearly foreseen for
this purpose. The lateral elongation force, which occurs during punching of the base holes,
might excessively press the hole stamp against the cutting case and consequently an easy
break might result.
8.
The machine has been designed in a manner to work with the pieces which can be placed
without having subjected the fingers or hands into the danger zone. For punching, mortising
and profile cutting of the short pieces ( for instance small sheet metal parts ), special tools,
scrapers and security components are pieces should be placed into the machine and taken
back suitable holding tools.
9.
Regularly check the screw connections and other fixings of all the blades and other parts as
well as the safe seating of the hole stamp and cutting cases. For example, should the hole
stamp ( punch ) get loose during the operation, there occurs the danger that the hole stamp
inclined over the cutting case so that the tool might break.
10.
Before each tool change, make sure that the machine is disconnected from main switch.
11.
Completely disconnect the machine from the net before you carry out any maintenance work.
12.
Never let the machine function without any inspection.
- 14
13.
When you perform works where big forces are existing, the work piece should be additionally protected through a block having an assembled roll or similar installation, which is to be placed on the machine.
14.
The machine capacity shall never be exceeded. For this purpose, check the" technical data" on this rules and compare the values with the information given on the manufacture plate. All
the capacity information is based on a material having a resistance of 45 kg/mm
2
15.
Should the hydraulic circuit flow be overloaded, the hydraulic oil will be led back to the reserve
tank over the overload valve until the pressure gets down again to the normal level.
Attention: HOWEVER, IT IS. NECESSARY TO UNDERLINE THAT IT MIGHT BE
DANGEROUS TO USE THE OVERLOAD VALVE AS A "SAFETY VALVE" IN O RDER TO
EXCEED THE MACHINE CAPACITY.
The producer presents all the instructions for a work protection and safety and hopes to have a good and full calibration with you, the users, in order to ensure that the maximum Level of safety could be obtained.

CONTROLS BEFORE PUTTING INTO OPERATION

1.
Press on the green " START " button in order to start the machine. In order to ensure this, make sure that the red off button (" STOP") rotates clockwise (or directly to draw).
2.
Make sure that the entries for hole stamp and cutting case are safety fixed.
3.
At the command table, change the status from "NORMA" to "ADJUSTMENT" ( Consider that the readjustment course is not automatic at this position. When you leave the foot pedal loose, the machine does not return to standby, rather it simply gets left).
4.
Make sure that the course limiter allows a maximum course. Now, press on the foot pedal so often that the hole stamp stays in the cutting case. Take care that the hole stamp is regularly arranged with the cutting case.
5.
Change the position from “ADJUSTMENT” to “NORMAL” at the command board. No w t he machine gets automatically back to the standby position.
6.
Check whether or not single cylinder perf orm, full course. Make sure that, no-hydraulic pres­sure occurs at the and of related course. In order to ensure that there is no air available in the hydraulic system, repeat the process several times (air might enter here during transport).
7.
Verify all tubes, hoses connections, branching and reserve tank for eventual hydraulic leakage.
8.
Fix again all the protection parts and remove al l loose subjects from the working zone of the machine
The machine is now ready for your job.

OPERATION OF THE MACHINE

Operation elements
All the electrical delivery of the machine passes through the main switch. In order to connect this, rotate the switch clockwise. To confi rm this, check that the control lamp starts lighten.
By pressing on the green “START” button, connect the motor (for the motor to be able to function, the “STOP” button should be disconnected. This can be realized by rotating the red button clockwise (or drawing this).
By pressing on the red “STOP” button, the motor will be stopped. The lightly pressed “STOP” button gets locked at command. In order to loosen the button and to cause the machine to function again, the “STOP” button will be turned clockwise ( or drawn ).
Note: The machine has two
pedals and double pistons. We designed two workstations to work at the same time; two operators can make two operations at the same time.

The pedal switch has three positions:

Over position
central position
lower position
If pedal is driven till the lower position and there remains fixed, the machine gets into the deepest punching position. Nevertheless, the machine doesn’t turn back to the standby position until the pedal is left loose.
The central pedal position allows the operator to effect unlimited positioning including over and down course. This central position is very practical because it allows the operator to carry out touching so that the work piece can be optimally positio ned.
The switch “NORMAL / ADJUSTMENT” ensures that the machine is operated at touch operation or performs production at norm al functioning.
When the switch is arranged on “NORMAL”, the machine performs a normal and full work cycle at each action of the foot pedal, that means the punch moves to the lowest position and then gets again into the standby.
When the switch is arranged to “ADJUSTMENT” the machine stops. When the pedal is left loose, the automatic back course at this position has been cancelled.

REGULAR LUBRICATION INST ALLATION

The machine is equipped with a central lubrication pump under pressure which is located at used, the system should be adjusted to a pressure of 1-3 bars. When the machine is at operation, a suitable pressure would be maintained, through which the system will get back into the previous filling pressure (approximately each 30 to 60 minutes).
- 16
ARRANGEMENT OF THE PUNCH TOOLS

IN GENERAL

The big punch bearing surface and the removable front block have been constructed in manner to allow a very wide range punch works:
Through the optionally obtained tools, the big holes in any form up to the diameter / quadrate as it is indicated in the capacity table can be produced. In addition, machining at overhanging position, with the removed front in addition, during machining at overhang, with the removed front block, the of U profiles of double T supports having diameters or eventually diagonals up to 38mm highest capacity can be punched.
The punching stamp is held though a holding ring, according to the size of the stamp (punch) one or two of the delivered adapters can b e used. The matrixes are fixed to the tensioning pl ate through a positioning screw. When the filled punch stamps and matrixes are be arranged, it should be paid attention to the screw is correctly placed on the machined surface of the matrix. In order to allow a suitable play area and to ensure that the material is taken out, the punch stamp scraper plate should be correctly adjusted, however it should not effect the stamp course. Attention should be paid to that the lower course limiting switch has been adjusted as per the instructions. When the holes are punched with sufficient material, a flat contact occurs at both sides of the scraper plate. The scraper forces can be important and unbalanced scraper forces can lead to the break of the punch stamp through the contact with a side of the scraper.
No material should be punched which is thicker than the stamp diameter. The quality of the hole is a direct finger appearance on the situation of the punch stamp and matrix.
When the scraper fingers are used for very big holes or irregular forms, the fingers should be equally position and adjusted in order to prevent and unbalanced scraper load.
Additional tools at this multi purpose wor k station allow bar and sheet metal bending wor ks, edge threading, tube threading, tube threading and general column positioning works.
- 17

In order to install or change the punch tools you will need the following tools:

Hook key Soc. head cap bolt key ( 6 mm ) Screw key ( 24 mm )
WHILE ORDERING SPARE STAMPS AND MATRIXES, PLEASE ALWAYS INFORM OF THE
FOLLOWING: MODEL, TYP E AND MANUFACTURING NUMBER O F T HE MACHINE.
Below we explain step by step now the hole stam p and cutting case are changed:
1)
In order to take out the cutting case, move the machine to a position where there is enough
2)
Disconnect the machine at machine switch
3)
Open the scraper, loose the coupling nut, fixing screws of the cutting case delivery plate a nd the M12 screws, which hold the cutting case. Remove the coupling nut together with the hole stamp and adapter. Remove the cutting case.
4)

5)
Connect the machine and than position at “adjustment”.
6)
Move the hole stamp slowly towards the cutti ng case. Push the cutting case delivery plate correctly so that the hole stamp and cutting case are completely arranged.
7)
Adjust the cutting case delivery plate in a manner that the cutting distance which remains between the hole stamp and cutting case is fully equal and draw the delivery plate fixed in this station.
8)
Check whether or not the receiving plate has been deviated during the drawing. If the cutting is not equal, you should repeat the point 8. as soon as the plate is fixed the cutting distance is equal, adjust the machine to “normal”.
9)
Take the scraper back then adjust the distance between the scraper and cutting case according to the thickness of the material to the machined.
10)
Adjust the course adjustment in such a manner t hat the shortest possible way should be left back.
11)
In order to protect the operations, fix the macralon protection before you start working.

PUNCH CAPACITY

The diagram shows the punch capacity curves of the XS-series depending on the material thickness and stamp diameter. (Based on a construction steel having a traction resistance of 45kg/mm
2
).
Diameter of the punch stamp D (mm). During calculation of the punch capacity it should proceeded according to the following formul a:
P = SHEARING SURFACE x TRANTION RESISTANCE
P = ∏×D × S ×TRANTION RESISTANCE

A calculation example:

A 20 mm hole will be necessary in a 12 mm thick homogenous steel sheet metal having 45kg/mm traction resistance.

This is valid the following:

Punching pressure = Shearing surface x tracti on resistance x 0.0098 and Shearing surface = Volume of the punch stamp x material thickness ( so the traction resistance Amounts to 45kg/mm2, 0.0098 is the fixed value for the calculation of kg/ m m

on KN
accordingly : 20x 3,142x12x45x0,0098 = 333 K N ( 33,3 Tons )

Attention :

Never punch with a hole stamp which is thinner than the material to be machined.

SHEARING, PROFILE SECTION CUTTING

The shearing unit has been equipped with a simple and strong fixing installation that can be arranged at any material thickness within the cutting capacity of the machine. A shearing delivery table having adjustable quides has been const ructed in order to allow a correct delivery of the material. The guiding can be arranged in a manner to allow the angle cuts up 45 of flange of angle profiles, which have been previously cut at the inclined cutting station. Alwa ys place the material from the entry side of the machine and make sure that the material gets fixed by a correctly adjusted fixing installation. If a full a full cutting is required, the biggest possible dimensions for the material to be cut at angles, amount to 70x70x10.
In case the shear blade should be grounded, grin d only the cutting surfaces. A re-grinding is possible up to a maximum depth of 0.8 mm. After the grinding the blades should be adjusted to a play of 0.1 mm.

NOTCHING STATION

The threading station has quadrangles punch stamp as a standard equipment element and is delivered with a threading table complete with adjustable lateral and rear counter holders, which essentially simplify the repeatable positioni ng of the material.
The sharp notching tools can also be constructed at t hi s wo rk station. Optionally, the units for narrower width of quadrangles or forms can also be delivered. Various uni ts are also available for the forming of bar ends.
A special feature of this work station is the possibility to fix some punch end units, that means tools for smaller punching works up to a punch pressure of 40 t ( characteristics can be supplied upon request ).
In case the grinding of the notching stamp is necessary, only grind the side and front surfaces
of the stamp. The matrixes have four cutting edges and should be turned in order to require new cutting.

MACHINE ROD AND LEVER READJUSTMENT

After a preliminary working period (about 5 to 6 days), it will be necessary to carry out arran-gement adjustments on the machine.
Punch rod
The arrangement of the rod will be realized with t he hel p of a “rod leading plate”.
This plate should be readjusted.
The related adjustment screws are located at the exit side of the machine.
In order to adjust the rod, proceed in the following manner :
Remove the punch stamp
Loosen the safety nuts
Readjust the rod adjustment screw (not to tighten too much)
Lock the screws with a safety nut
The adjustment control is to be made through a few in and out movement ( about 6 times ) of the rod. Then the machine should be checked in adjustment mode. If the rod does not move here, the plate should be readjusted and the process m ust be repeated.
Shear lever
The machine should be disconnected before car rying out any readjustment works on the shear lever. The readjustment of the pressure lines shoul d be carried out from the delivery side of the machine.
For this purpose, proceed in the following manner:
Loosen the safety nuts ( M24 ) only of the three pressure line positions
Until alight pressure is obtained, rotate the adjustment screws clockwise
Tighten the safety nuts again and check the m ovement ability
Attention: The grooving stamp and matrixes are now not any more arranged. Please adj ust
these again before the use of the machine.

TRUE PUNCHING
This machine is equipped with a single piston. When you work with the machine on shearing station with max shearing and then change to punching station the overtravel may cause the holding nut (A) to contact the scraper(B) and damage these components. (Figure - 1)
To avoid this, after working with the shearing tool you must make sure that its adjusted back to working with punching tools.
Re-adjust the stroke so that when the punch goes down it does not contact the scraper. This means that you must adjust the stroke as shown in Fi gure - 2 by l eaving enough travel stroke (4 – 5 mm is sufficient)
shown in Figure – 3. Remember that, at this adjust ment if you work with the punch you will damage the scraper and the tool holder
