1.0mm Tubular Closer 630/7f For 7/7 Galvanized Wire Rope

China Factory Tubular Closer 630/7F For 7/7 Galvanized Wire Rope

ire Strands

The first step in wire rope creation is the production of wire strands where wires are wound around a single core wire. The number of wires included in the strand is dependent on the specified strength, flexibility, and size requirements of the rope. Once the strand is completed, it is straightened before being moved to wire rope construction.

Strand Patterns

Like wire ropes, strands have different patterns; patterns are the arrangements of the wires and their diameters. Though most strands have a core, there are strand patterns that have three or four wires without a core that are referred to as centerless strands. The design of each strand pattern is meant to enhance the strength of the wire rope and improve its performance.

These machines are designed for the production of high tensile steel, copper and aluminium strands; the closing of wire ropes; the making of flattened strand and the assembly of insulated cable conductors. The machines accept a range of bobbin diameters from 5in (125mm) to 40in (1000mm) and are constructed to accept from 2 to 50 within the rotor. Exact requirements can be varied to suit any particular need.

Bases All rotor sections machines are constructed on heavy section rolled steel channel bases suitably braced and welded together. Tubular Body The rotor body of the machine is constructed from appropriately sectioned steel tube. Port openings are correctly proportioned to provide maximum loading and unloading facilities. During manufacture the tubes are dynamically balanced to the finest limits using modern techniques. The tube is supported in the strander on encircling split roller bearings. These provide a perfect operating medium for the high speeds and long operational life that are demanded of the machines. Whilst our recommendation would be for customers to seriously consider the split roller bearing design, we have for many years also manufactured, and can still supply, the tubular strander with non-metallic under rollers. These rollers are amply proportioned and designed to give maximum life. Cradles The Cradles are of best Cast Steel and are supported in heavy ball bearings in such a manner as to be readily removed from the rotor if necessary. The front of each cradle trunnion is bored for a well bell-mouthed tungsten carbide Wire Guide. The Cradles are each fitted with a special spring loaded latch to firmly secure the bobbin.
