3. Equipment description:

3.1 Composing die and Deformer

Different composing dies are loaded inside the die box for different size of wires. Manually adjusted by guide screw.

Each deformer wheel is manually micro-adjusted, hydraulic cylinder opening to prevent broken lot strands.

3.2 Skip stranding machine 1+6×1120

For the skip stranding machine, each set consists of 7 pieces of 1120 bobbins, is driven by single motor. The transmission shaft and Rotating body are connected by synchronous belt. With stable lay pitch, it guarantees the lay lengths of stranded wires in different dimensions are in accordance with GB/T5224-2003. Big size bearings support the threading barrel to get enough space and make threading very easy. Each revolving part are connected with one another by a GRP cambered plate, which enables it reach the speed request of higher stranding machine. 7 single wires pass through each own position without interference with each other. The bracket of cylinder escapement is movable, makes it easier for transfer and balance adjustment. Damping system is loaded on the bracket to adjust the mutative tension of each single wire during production. Integrative bottom frame can make sure the bunching machine works steadily.

Max. Rotating speed: 680rpm

Driving motor: A/C, 90KW, 1500rpm

Bobbin size: DIN1120

Dia. of flange: 1120mm

Dia. of barrel: 630mm

Total width: 964mm

Inner width: 840mm

Max. weight: 4000kg

3.3 Intermediate frequency tempering furnace

Use full digital microprocessor control circuit to closed-loop control of equipment output power and running speed, realizing automatic tracking function of power and speed. . In order to insure control the tempering temperature at ±8°Cof steel strands ( thermodetector will show temperature), machine will use movable heating method. Once equipment stay in normal running program, steel stranding wire can reach the process required temperature in short time, this can avoid the non-tempering wire when re-start, reduced metal consumption.

Rated power: 600Kw

Processing temperature: 380-420°C

3.4 Tension system

Tensioning system consists of two sets of tension equipments. Two tension wheels rotate same way and make the wire tensioned between the wheels. The wheels are welded by 42CrMo forged rings, machined tooled and then quenching processed, with surface hardness of HRC≥58. Cone gears are used in speed reducer.

Max. Speed 100m/min (Ø15.24)

Max. Tension 155000N (Ø17.8)
