4.1.5. Structural form: the main
engine adopts 12 + 18 two-stage cage layout, and each section of cage is
divided into four equal parts. The cage is carried by two large double row
roller bearings, which are supported by gearbox and front support. The cage
body is composed of cage, gearbox, front support, brake system, base, etc.
The whole machine is driven by 75kW variable frequency motor.
4.1.6. Synchronous stranding: the
12 and 18 reel stranders have the function of synchronous stranding up to 30
cores. The same speed box is used for the two sections of stranding cage, and
12 synchronous pipes are preset inside the 18 reel stranding cage to complete
the stranding of up to 30 wires in the outer layer.
4.1.7. Hanging way: the process of
tightening and loosening the coil is completed by the worm gear clamping
structure driven by the electric wrench, and the turbine box has the function
of automatic locking, which is convenient, fast and safe to operate; The
turbine is supported by bearing, which is accurate in positioning, not easy
to wear and avoid jamming. The coil is installed into the winch cage through
the lifting device in the workshop.
4.1.8 Structural features of
gearbox and front support: the internal gear of gearbox is made of 20CrMnTi
material, carburized, and the grinding accuracy is grade 6. The 6-stage speed
change of the box has positive, negative and neutral gears, and the inside of
the box is sprayed and lubricated by an independent oil pump motor. The front
support is made of gray cast iron with lost foam casting process, which is cast
and processed as a whole, with beautiful appearance and high strength.
4.1.9. Structural characteristics
of the hinge: the frame adopts the plate CNC laser cutting and blanking, and
the large bending machine bending processing. This process can minimize the
welding seam and improve the overall structural strength. After the overall
assembly and welding forming, the high temperature annealing treatment can
eliminate the internal stress, and then the large machine tool is processed
as a whole to ensure the concentricity, stable operation, high mechanical
strength and no deformation for a long time.
4.1.10. Bottom structure: the base
is made of high-quality plate and rectangular square tube, with beautiful
appearance and high structural strength.
4.1.11. Braking system: each
section of the main engine is equipped with multiple groups of flat air
brakes. When parking, the driving motor stops working, and all brakes act at
the same time. The whole braking process is efficient and stable.
4.1.12. Line breaking and parking:
equipped with advanced dxj full-automatic vector pulse line breaking and
parking protection system, the line breaking monitoring can be accurate to
each coil, and the system can stop and brake in time when the wires in the
coil are used or broken. The monitoring system is controlled by wireless
communication to reduce wire laying, improve monitoring accuracy, reduce
operator allocation and improve production efficiency.
4.1.13. Pay off tension: mechanical
friction is used to provide tension, and the tension is adjusted manually.
The tension output is even.
4.1.14. Pre deformer: a single wire
pre deforming device is installed at the front end of each section of main
machine to prefabricate the stranding pitch and improve the quality of
4.1.15. The front end of each
section of the winch cage is equipped with: emergency stop, inching button,
and a 220 V power supply fast plug row, which is convenient for operation and
4.1.16. Wear resistant alloy
nozzles or wire rollers are set at all wire holes and easy to scratch wire
4.1.17 Safety cover: one side wall
safety net made of perforated plate.
4.118. Others: a group of 30 reels
is added to the 18 reel winch cage, which can be interchanged with the
original 18 reel reels for synchronous stranding
