2. Equipment description:
2.1 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
2.2 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.
2.3 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)
Motors: No.1 A/C, 250KW, 1000rpm
No.2 A/C, 200KW, 1000rpm
Dia. Of wheel: 2×2050mm
Number of driver groove 5, V shaped
Number of No.1 wheel groove 4, U shaped
Number of No.2 wheel groove 4, U shaped
