1. INFORMATION ABOUT THE MACHINE
1.1 Machine identification
1.2 Normal usage of the machine
The machine has been basically disigned to shape cold forge materials. It scrolls bars, it makes spirals of
flat bars, etc. All drawings that can be made with a rotary head and a stand point will be easily makeable by
using this machine. It will only be limited by the room it accupies and the engine power.
A set ofstandard tooling is supplied along with the machine, with which you will be able to make most of the
basic shapes. However the manufacturer can provide the user with the fitting mould for the head, so he can
create his own shapes.
1.3 Noise caused by the machine
In this case noise could be considered as non- existent under normall working conditions.
1.4 Vibrations
Like noise, vibrations are almost non-existent for this a fixed machine and it has got a low head rotation
speed.
1.5 Operative’s natural working place
The first zone is the machine bench, to the left of the drive where the twisting operation and the coil
making is made.
Si se produce un accidente por negligencia del operario, por no atenerse a las normas de
seguridad expuestas en el manual, PRADA NARGESA S.L no se hace responsable.
Trademark Nargesa
Type Twisting machine
Model MT500A

INSTRUCTIONS BOOK OF FORGING TWISTING MACHINE MT500 A 6
The second zone is the tooling area, to the right of the drive, where we make shapes by using a rotary
drive and a fulcrum.
1.6. Description of the machine
The machine is equipped with a 5 HP engine and the reductor which transmits rotation to the head by
means of a cog wheel.
It has a box to keep the tooling and a stand table made of a welded and folded steel plate.
1.7. Description of accessories
The basic accessories the machine has are the ones to fit the head to make the different shapes. It is
provided with different stand points, and clamping spots for materials. In the last chapter of this manual
there are a series of operations all of them explained step by step by means of photographs.
1.8. Description of safety devices
Gears and moveable parts are covered with the exception of the rotary head.

1.9. Basic characteristics of the tooling that can be fitted to the machine
Making sure that the accessories that are to be fitted to the machine have the same clamping so they can
be thrown out or get loose is the only thing to bear in mind to use them.
1.10. Information related to the electrical equipment
The machine has a 230/400V three phase engine, connected star like when the line tension is 400V and
connected in triangle when the three phased line tension is 230V, as it is indicated below:
Star picture Picture triangle
Likewise it is necessaryto change the input transformer terminals for the change of tension. Input 400 V.
(Terminals “0”and “400”). Input 230 V. (Terminals “0” and “230”).
This modification must be carried out in the connector to the electric card.
See the sketch to get the steps in detail:
1.11. Instructions to connect it to the power supply
It must be only connected to one power supply in the indicated source. If the line tension is not the correct
one, then it will be necessary to change the connection of the engine bobins, the frequency inverter must
be replaced by one with three phase 230V input.
It is very important to connect properly tha machine to the ground socket.

2. TRANSPORT AND STORAGE
2.1. Transport
Transport will made by means of a forklift truck.
2.2. Storage conditions
The machine should be stored in place with the following requirements:
- Humidity between 30% and 95% without condensation.
- Temperature from –25ºC to +55ºC or +75ºC for a length of time no longer than 24 h.
- It is advisable not to pile up machines or heavy objects on top of them.
- Do not disarm for its storage.

INSTRUCTIONS BOOK OF FORGING TWISTING MACHINE MT500 A 9
3. INSTALMENT AND STARTING UP
3.1. Instrucons to x it
When the machine is put down by the crane it will be necessary to do it correctly so it doesn’t have to be
moved once it is on the floor. If it isn’t possible then put in a moveable base in order to transport it to the
finel proper location.
The machine will be fixed on the floor by its own weight, thus it is very important to put it in a flat and even
surface.
3.2. Admissible outer conditions
- Environmental temperature: Between +5ºC and +40ºC without exceeding +35ºC as average
temperature during 24h.
- Humidity: Between 30% and 90% without water condensation.
3.3. Safety systems for the operative
The final place location for the machine must be estimated counting on the space that the material bar will
be occupating while being shaped.
3.4. Periodicity of revisions
Check up the oil level every 2000 hours of performance.
Never ever touch the material bar while the machine is performing.
