Item 01 Un-coiler;
Technical Characteristics :
Type : Double mandrel
Coils max outer diameter : 2.000 mm
Coils min-max width : 35-170 mm
Material max thickness : 2 mm
Un-coiler rotation : Idle
Functioning :
It support the coils during unwinding.
The design with double mandrel let the operator load the next coil during normal line
operation and reduce the time losses during production.
Item 02 Strip joint bench;
A complete and working unit for the welding of strip head coming from the un-coiler with the
strip tail coming from the horizontal spiral accumulator.
Strip Cutting
It is transversally performed, with regards to the strip movement, by means of a blade
hydraulically commanded by the operator. :
Hydraulic clamp
01+01 units hydraulically controlled. They are placed before/after the transversal shear and fix
the sheet during the head welding operation (this task is performed manually by the operator
with an electrode welder - excluded from our supply).
Tasks performed by means of the operator
· Unwinding of the strip coming from the un-coiler
· Introduction of the strip into the welding bench
·
Description Levelling of the strip: after butting and welding it is necessary a levelling operation to
The machine is composed by two independent spindles with strip guiding wheels mounted on
a central column. All equipment can rotate on his vertical axe.
Functioning of the machine:
The machine can accumulate the strip on one side while the other side is down loading the
already accumulated strip to feed the tube mill.
When one side has finished the line must be stopped, the accumulator rotate on his vertical
axe and then re-start the production

· Hydraulic power unit
· D.C. drive
Machine description
The machine is composed of a strong base made by welded steel plates, on the top part
are placed the rails on which the cutting trolley runs by ball bearings.
The trolley is composed of a steel frame on which is placed the cutting system, that consist
by a tilting arm holding the spindle supported by large rolls bearings.
The spindle revolution is controlled by an A.C. motor through toothed belt and pulleys.
The cut stroke of the tilting arm is assured by a hydraulic cylinder controlled by a servo
valve, that through the electronic system with a proper software optimizes the cut speed
and stroke, depending from the pipe diameter and thickness.
The cut system is completed by a double adjustable vice, controlled by hydraulic cylinders,
able to receive the different type of jaws for the various pipes dimension.
The motion control of the carriage is obtained by a D.C. motor connected to the pinion by a
self aligning coupling and gear box, a disc brake provide the motion stop in case of
emergency.
On the two ends of the base are placed the shock absorber able to stop the trolley in case
loss of power or emergency, while a locking system hold the trolley in idle position with the
pinion disengaged from the rack to avoid their damage.
Item 06 Run Out Table
Length : 25 m.
It is composed of a roller table “V” shaped, and it’s able to run out the pipe on both side.
The roller are driven by electric motor with inverter and a series of tilting arms provides the
offloading of the pipe into a collecting system.
