THE TRS/C/Sy 250 sawing machine features recent
plant solutions and technical solutions that have been
introduced to fit the increased production capacity of
modern extrusion lines. The saw has cutting tools inside
the planetary group (rotor) and has a mechanical system
to control the position of the cutting tools on the external
pipe wall around the cutting area.
The cutting unit has two cutting arms each with a different
cutting tool: one is a special Sica design milling cutter for
chamfering the pipe (which has been modelled based on
the particular shredding characteristic of the material), and
the other is for the final swarfless cut of the pipe.
This solution allows a clean chamfer and cut without any
chips inside or outside the pipe. TRS/C/Sy 250 processes
pipes from 32 to 250mm diameter. For pipes up to 12mm
wall thickness it can cut and chamfer, while pipes up to
40mm can only be cut.
Everbell/H 315 PSP is an automatic belling machine for
shaping O-ring sockets for PP and HDPE pipes for indoor
draining and sewage applications (which can also be
used for PVC-U pipes). The machine can socket solid wall
pipes or multilayer pipes from DN 50 to DN 315 with pipe
lengths from 0.5m to 6m plus socket. The H version of the
machine features heating and cooling systems that reduce
thermoforming time.
The first heating station, instead of the traditional contact
oven, has an oven with lamps to emit IR shortwaves.
The cooling station uses an exclusive Sica-patented
convective cooling system with a cooling fluid that goes
through an internal refrigerating system.
The forming stage uses a patented Sica PSP system
(Permanent Socket Profile), which produces an O-ring
socket with an internal dimensionally calibrated surface
and a stable shape.
