630X12+1X1250 Bobbin Bow Type Tubular Stranding Machine

1. Application:

This machine is mainly used for the stranding of copper strand, ACSR, steel stranding  wire, etc.

2.Feature:

 The unit is designed with large bearing type, with stable and reliable operation. The design structure is 12 + 1, and the central pay off is placed at the front end of the 12 reel cage to reduce the threading distance, so that the central cable is not easy to bend. The integrated thin oil lubrication system does not need a single oil tank.

The machine adopts PLC and touch screen of human-machine operation interface to coordinate the electrical working state of all parts of the whole machine. The electric control system is advanced in technology, convenient in operation and reliable in operation.

4. Main components:

• Ø630/12 main stranding cage
• Ø1250 front bow type pay-off
• Assembling die holder
• front side straightening device
• Ø1600  double wheel double drive  traction device
• Meter counter
• Ø1600  portal type take-up and traverse line
• Electrical control system
• Mechanical  Transmission system

• Use bobbin size:PN1250（buyer provide bobbin size）
• Loading mode: top structure, mechanical locking, safe and stable, not easy to be thrown out, convenient for loading and unloading the line tray, and the line tray is loaded into the cradle with the help of the crown block in the workshop
• mechanical disc friction tension is used for setting out, and the tension can be adjusted manually
• there are three bows made of special steel for setting out, and the wire in the 24 coil winch passes through three bows and is twisted at the junction
• the pay off rack is supported by two sets of large bearings, driven by toothed belt, and driven by front and rear double drives, which reduces the torque borne by the winch and improves the operation stability
• front bow type central setting out reduces the threading distance of large diameter central wire rod, avoids wire scratch and bending. The setting out is designed to be connected with the main machine, with reasonable structure design and stable operation conditions.
