5. Close the protective hood. Drive the carriage forward with switches 13 and 14
until the pin goes into the pipe. Press the power off. Open the hood. Adjust the
slide so that the forming pin slightly touches the inner surface of the pipe. Or you can use
the values of the setting value table according to the pipe size. The position of the slide
can be read from the scale on it (see picture below).
Scale of the slide
In case of hot forming (option), it is recommended to leave a space of 1 mm between the
inner wall and the pin.
Tighten the three locking nuts carefully (see picture on previous page.)
5. Drive the moving carriage to back position with switches 13 and 14
6. Open the clamps with switch and remove the pipe.
7. Close the clamps with switch
.
8. Set the length of the part of the pipe which is to be flanged “Start pos.” to the program
(See chapter 6.2.5). A recommended value for this setting is, that the display readings
indicates 23mm + the thickness of the buffer plate used, thus N (See 6.2.4., point 11). For
instance, if the buffer plate is 4 mm thick, the setting of the scale should be 23mm + 4mm
= 27mm.
¨
NOTE! The value of the “Back pos.” has to be 60mm larger than the value
of the “Start pos.” For example if the “Start pos.”= 25mm the “Back pos.”
has to be at least 25mm + 60mm= 85mm.
9. Drive the forming pin to the flanging position with switches 13 and 15
.
10. Drive the moving carriage forward until the potentiometer stops it.
11. Open the clamp and place the pipe to the clamps so that the pipe end is against the
forming pin. If the pipe does not lie evenly in the clamps, knock the pipe in to the clamp
with a soft hammer. Close the clamps. Be careful when closing them.
12. If you have the cold forming mode selected, the machine is ready for trial flanging.
