New High-efficiency Stranding Equipment-JSHφ1600 Stranding Machine

1. Preface
The conductors of 19-core and below power cables are allowed to be stranded in the same direction and at the same pitch in layers. This requires a high-efficiency, low-cost stranding machine to meet market demand, new high-speed stranding equipment in the 1600 bundle stranding machine, the highest speed of the machine stranding bow up to 350r/min, compared to the production of such products as frame stranding machine, tube stranding machine, the machine has a low price, high efficiency, covers an area of less, etc., is currently 19 cores and the following power cable conductor core stranding The most cost-effective equipment.

3. Main components and structural features of the equipment
The JSHΦ1600 stranding machine is generally configured as shown in Fig. 2 and consists of a simple pay-off frame (Fig. 2), a rotating mould base, a single-wheel rotating traction machine, a medium 1600 double-twist main machine and an electric control section. The main components of the whole production line are the rotating die holder, the single-wheel rotating traction machine and the 1600 double-twist mainframe, and the main structural features of these components are introduced below.

3.1. Rotating mould base
The role of the rotating die base is to make 19 single wires stranded into the stranding die in an orderly manner, as shown in Figure 3, the die base is mainly composed of the rotating die head and the dividing plate. The dividing disc is used to introduce the 19 single wires into the stranding die in layers, while the disc can be moved back and forth to adjust the angle of entry of the single wires into the stranding. The rotating power of the rotating die comes from the single rotating traction wheel, which is connected by a synchronous belt and ground shaft, it rotates synchronously with the traction.
Improving the surface quality of the finished stranded wire.

3.2. Single-wheel rotating traction machine
The main role of the single-wheel rotary traction machine is to form the stranding pitch, mainly by the front and rear support, simple, traction wheel, transmission system and other components. The main body is driven by the main motor through the synchronous belt to achieve high speed rotation of the stranded line, the traction wheel is driven by a separate motor through a set of drive rotation to achieve traction, the traction wheel is fixed to the simple body, and the simple body - the rotation, in order to compensate for the influence of the simple body rotation on the speed of the traction line, a set of differential wheel system is added to the transmission system, thus ensuring the stability of the stranded pitch.

3.3.Medium 1600 double twist mainframe
φ 1600 double-twist mainframe is the core component of the stranding machine, as shown in Fig. 5. It is the middle frame picked up by two large support blocks on the left and right, the frame is hollow set on the spindle at both ends by means of bearings, it is not moving. On it are integrated components such as auxiliary traction, line discharging device and take-up device. The rotation of the stranding bow is driven by the synchronous pulleys at both ends through the main motor, which rotates in the same direction as the single wheel rotary traction, at half the speed of the rotary traction.
4. Three kinds of stranding equipment yield comparison
Known: aluminium wire in 2. 5mm structure 1 + 6 + 12 pitch 100mm material density p = 2.7t / m'
Hourly output is calculated as follows:
Finished wire diameter: D=2. 5x5=12. 5mm
Wire speed: V=150x100=15000mm/min
V F 300x100-30,000mm/min
V -600x100-6000m/min
According to the formula: output G=Vx60x (D/2)2xnxp gives G frame=0.3 t/h G tube=0.6 t/h G east=1.2 t/h
The output per hour of a buncher is 4 times that of a frame winch and 2 times that of a tube winch. Or the output of 4 frame stranders is equivalent to the output of one beam stranding machine, so the cost performance of the beam stranding machine is incomparable to the other two machines.
5. Main applications of the equipment
The structural features and stranding process of the JSH 1600 stranding machine fully reflect the new and efficient characteristics of the machine.
So far, the equipment has been produced in several units and has been put into use by the users, mainly for the stranding of 19-core power cable conductors.
In the production of 19-core conductors, smooth alignment, stable pitch, easy operation and high production efficiency are required. Through the above
The structure of the stranding machine is described above, the 1600 stranding machine produced by our company fully meets the requirements of cable production.

6. Conclusion
The new high-speed stranding equipment in the 1600 bundle stranding machine has a reasonable structure, easy operation, high speed and high efficiency, and will be the first choice for the stranding of 19 cores and the following power
Cable conductor core stranding preferred equipment. With the continuous development of the structure and type of equipment, the use of the stranding machine will be more
The 1600 stranding machine has a reasonable structure and is easy to operate.
