1. uses
It is suitable for the stranding of large length, large cross-section aluminum / aluminum alloy wire, bare copper wire, steel core aluminum strand, sector conductor and cross-linked compact cable core.
2. Performance characteristics:
(1) the wire reel is divided into four parts around the hinge cage, and is centralized on the reel. The equipment has high rigidity strength, good overall performance, small rotation inertia and high operation speed.
(1) the equipment traction drive adopts 36 grade gear box, double active and double traction device, with the maximum traction force up to 15 tons. The traction device adopts natural shunting to avoid abrasion of wire core during shunting.
(1) the tension is even when the coil is full to empty.
(1) the equipment adopts the most advanced cut-off stop device at present, which can directly control each wire panel. When any wire panel is cut off, the main engine will automatically shut down. Ensure the repair after disconnection, especially suitable for the production of power cable and high tension cross-linked cable.
(1) the equipment can ensure that 630 mm2 copper core with compact density over 90% can be drawn and twisted to meet the needs of large cross-section cross-linked cable stranding.
2. Structure:
In general, the cage of rigid strander can be collocated freely according to the needs of production wires. The main structures are: 6-cage, 12-cage, 18-cage, 24-cage and 30-cage. For example, 6-cage means that 6-bobbin can be installed in a cage. If the guest's cable contains 37 copper wires or aluminum wires, the structure should be 1 + 6 + 12 + 18 cage. The model of loading cable bobbin determines the model of the machine. For example, if the guest uses 630mm cable bobbin, the model of the machine should also be 630 / 1 + 6 + 12 + 18 bobbin
3. Load bobbin system: three kinds in total.
(1), manual load: the main operation is to install the wire reels one by one into the cage by using the crane in the factory. The advantage is low cost. If the number of wires produced is relatively small, you can choose this way, such as under 24 wires. The disadvantage is that the number of wires produced is relatively large, such as 54 wires. When the wires are used up, the wire reel needs to be replaced frequently, which increases the cost and time of workers.
(2) side bottom 45 degree load bobbin system:
The main working principle is that, under the side of cage, the load and unload bobbin device similar to the cart is installed. The user puts three wire bobbin on the cart, and the wire bobbin can be directly installed on the cage through the button. This method is also the most widely used in China and the world. The cost is average, just do simple.
(3) side load bobbin system:
The principle is the same as the previous one, except that it is to install the cable bobbin horizontally from the side to the cage. This method is very popular with European cable factories, and is generally widely used in large factories. The main disadvantages are: high cost, large machine floor area, difficult maintenance.
4. Drive form: the first kind, ground shaft drive: low cost, maintenance, widely used. Second: independent motor: high cost, fast operation, new technology.
5. Other accessories: for example, pay off, take-up, meter counter, pressing device, etc. are all matched by the process of cutting off the guest line.
6. How to distinguish the quality of machines: generally, the factory technology with a long history is very perfect. When you visit the factory, there are many rigid stranders in the warehouse of the factory, which proves that the factory manufactures this kind of machine all the year round, and the sales volume is large. Because of the sales volume, its technology is more mature. For foreign purchasers, it is very important to check the machine guest list of the exporting country of the factory. Generally, large international factories can purchase this factory, and they are recognized by the professional team, so this is also a decisive factor.
