4.2.3 The end-shaft type of the pay-off frame,
the frame adopts high-quality plate numerical control cutting and overall
bending process, with few welding positions, clean appearance, high
mechanical strength after high temperature annealing, and final overall
boring processing with high precision and stable operation.
4.2.4 The spool adopts pneumatic release, air
clamping, and pneumatic stop. It is convenient, fast and safe to load and
unload the spool. It has a pneumatic self-locking function. The cradle base
is equipped with a spool bracket. The pay-off in the cradle frame adopts the
friction belt tension control device, and the manual operation surface is
adjusted, which has a long life and is not easy to malfunction.
4.2.5 At the exit of the pay-off end in each
pay-off frame, a set of tic-tac-toe wire rollers is added, and a set of wire
rollers is also added to the outside of the outlet shaft head, which is
directly extended to the outer guide wheel group of the cylinder, effectively
avoiding the core of the wire. Scratched.
4.2.6 The rear and front ends of the cylinder
are supported by bearings. The middle is supported by a "large
bearing". The large bearing adopts a new type of oil and gas lubrication
and labyrinth seal, which has good lubrication effect, short oil return
distance, fast cooling speed, multiple functions, and no need for a separate
oil tank.
4.2.7 Each large bearing has a high
temperature overload shutdown protection function, which is easy to maintain.
4.2.8 The cylinder body is made of
thick-walled steel pipes, the internal stress is eliminated before
processing, and the dynamic balance is corrected after processing, not
exceeding 20 wires, and the cylinder wall thickness is 25mm.
4.2.9 The main engine adopts butterfly,
multi-group, pneumatic and caliper brake device, which is sensitive and reliable
in braking.
4.2.10 The main machine adopts the external
wiring method, with a longer and thicker barrel, a large wire hole, and
multiple well-type guide rollers, so that the wiring is smoother, no bends,
no scratches, and no hopping.
4.2.11 The front and rear supporting seat and
the middle large bearing seat of the main engine are all made of gray iron
cast material with lost foam process, which is not shaped, fully absorbs
vibration, reduces noise, and has a beautiful appearance.
4.2.12 The main engine adopts a new type of
front drive, the cylinder body does not bear torque, and the cylinder body is
fully prevented from cracking. Using large-modulus toothed belt transmission,
effectively avoiding loss of rotation.
4.2.13 The monofilament pre-deformation device
is composed of multiple sets of guide wheel discs, including a positioning
disc, two fixed guide wheel discs, and a sliding guide wheel disc. The
distance between each group of guide discs is adjusted according to the
curvature of the wire core to realize the modification. , The whole set of
device is installed on the main shaft extending from the twisting head, the
structure is intuitive and easy to adjust.
4.2.14
The cylinder body is installed on an integral welded base, which is made with
the help of a special platform, and then finished by a planer, which is easy
to install and has high concentricity.
4.2.15 The protective cover adopts a push-pull
structure, and the sliding track adopts "linear bearings". The
safety cover of the whole machine does not shake and no noise; the protective
cover has the function of automatic parking when the cover is opened; the
operation surface of the machine body is equipped with infrared close to
parking function, and multiple functions , Effectively improve the safety
protection level.
4.2.16 Separately placed square, side-by-side
parallel mold base, beautiful and generous, the inner cavity size is 90×90mm
