4.2.9. Structural form: the main engine
part adopts 6 + 12 two section winch cage layout, and each section of the
winch cage is of 4 equal structure. The winch cage is carried by two large
double row roller bearings at the front and rear, and is supported by the
gearbox and front support. The winch body is composed of the winch cage,
gearbox, front support, brake system, base, etc. The whole machine is driven
by 45KW variable frequency motor.
4.2.10. loading bobbin mode: the tightening and loosening process
of the coil is completed by the worm gear clamping structure driven by the
electric wrench, and the turbine box has the automatic locking function,
which is convenient, fast and safe to operate; the turbine is supported by
the bearing, which is accurate in positioning, not easy to wear and avoid
jamming. The coil is
installed into the winch cage by the lifting device in the workshop.
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 interior
of the box is sprayed and lubricated by an independent oil pump motor. The
front support is made of gray cast iron made of lost foam casting technology.
It is cast in one piece and processed as a whole. It has beautiful appearance
and high strength.
4.2.12. Structural characteristics of the cage: the frame adopts CNC laser cutting and blanking of
plate, and large-scale bending machine is used for bending. This process can
minimize the welding seam and improve the overall structural strength. After
the overall assembly welding, the high-temperature annealing treatment can
eliminate the internal stress, and then it is processed by the large-scale
machine tool to ensure the concentricity, stable operation, high mechanical
strength and no deformation for a long time.
4.2.13. Bottom construction: the base is
assembled and welded with high-quality plate and rectangular square tube,
with beautiful appearance and high structure strength.
4.2.14. Braking system: each section of
main engine is equipped with multiple groups of plane air compressors. When
parking, the driving motor stops working, and all brakes act at the same
time. The whole braking process is efficient and stable.
4.2.15. Line breaking and stopping:
equipped with advanced full-automatic vector pulse line breaking stop
protection system, the system can stop and brake in time when the wire in the
coil is used or broken.
4.2.16. Pay off tension: the tension is
provided by mechanical friction, and the tension is manually adjusted. The
tension output is uniform.
4.2.17. The front end of each section of
main engine is equipped with single line pre-former device. Prefabricated stranding pitch to improve the
quality of finished wire rod.
4.2.18. The front end of each section of
the winch cage is equipped with emergency stop and inching buttons, and the
220 V power supply is fast inserted, which is convenient for operation and
4.2.19. Wear resistant alloy wire nozzles
or wire rollers are set at all wire holes and easy to scratch wire positions.
4.2.20. Safety shield: U-type push-pull
safety protection net is adopted.
4.3. assembling die holder
4.3.1. Each section of stranding cage is
equipped with a combined line die base and a group of rolling die base. The
die base can be used to form cable by drawing or pressing at one time.
4.3.2. connecting die base and the rolling
mould holder are installed on the same base, and the wire clamping die base
can adjust the distance before and after the cable's advancing line
4.3.3. 6 winch cage is equipped with
single combination line device
126.96.36.199 winch cage with line pressing
4.3.5. The inner cavity size of the thread
closing die base is 90x90mm
4.3.6. The adjustable distance of closing
die seat is 300 mm
