TWISTING MACHINE MT150 A INSTRUCTIONS BOOK 13
6.3. Equipment performance
The system described offers the chance to work in two different modes: manual mode and automatic mode.
6.3.1. Manual mode
The machine works this mode on default, however it is to be remarked that working on the automatic mode is
better, whenever there is a considerable mass production on the same memory.
In manual mode, the user may turn right or left by using the two buttons previously mentioned, so the torsion
can be carried out on his will and desire.
Performance is as simple as when pressing one of the buttons , the machine turns until the the user stops
pressing it.
Once the user thinks he’s got a good point start the torsion of a piece; he inserts it in the mould of the machi-
ne and makes the torsion of that piece, to one direction or the other, depending on the selected button. In
order to finish the torsion just stop pressing the button that was being pressed.
Now that we have twisted the piece, it is necessary to press the button "Left turning"or "Right turning" in order
to pull out the piece since it happens that it is difficult sometimes to get the pieces out once the operation has
been finished.
(Always bear in mind all restictions concerning the kind of torsion and that the pulling out will always be made
the opposite direction of the torsion, and it will make the machine go back a few degrees to enable the co-
ming out of the piece.
7.3.2. Automatic mode
The performance principle of this machine is the same of that one at the Manual mode, the difference lies in
the fact that this mode is used for the mass production of differen pieces,which makes a bit unuseful the use
of the machine in the manual mode.
First, once the user has inserted the mould in the machine, he should specify the starting point of the torsion
to be made. It is necessary to press the "Programming"key then (it will read in the display a label saying
“Define starting point of the torsion").Then he should specify the point the machine requires to define the tor-
sion by using the the buttons for "Left turning"and "Right turning". So when he finds the proper point to insert
the piece in the mould, it is required to stop pressing the turning button to either direction, and to press again
the "programming" button (There appears a label on the display similar to that of "Define kind of torsion").
Once we have reached this point, the user should select whether he want to make a round or square torsion,
since he has alrady put the piece in the machine.in order to do that he has to make it by using the button, no
matter if it is the aforementioned one "Round torsion", or the "Square torsion"one (It will appear a label on the
display similar to "Define kind of torsion", NºP:00 Reference: 0000". It is important to point out that when ma-
king the circle torsion it is only permitted to do it in left direction, for safety reasons, it doesn’t happen the
same when it comes to square torsions since they can be made to both directions. However once the torsion
has been started to one side, it is not possible to go back or change its direction until it has been completely
finished.
