Specifications

Rigid frame machine works to strand long bare aluminum wire and bare copper wire. stranding machine frame stander rigid strander

 

1. Features

The machine is used to strand bare aluminum wire and bare copper wire. The bobbins are fixed separately in 4 equal positions on the circumference of the stranding cage to make it easy for loading and unloading. It features high rigidity, good integrity, and small inertia of rotation but high running speed. The machine is complete with 36-stage transmission gearbox, twin motorized twin haul-off device. Wire-divider wheel is applied in a natural way to prevent wire from scratching during stranding. Pay-off tension is controlled by pneumatic and mechanical tensioner to ensure uniform tension in full or empty bobbin. In addition, the running machine stops instantaneously on wire breakage monitored by the unique automatic detector provided on each bobbin.

4. Main Components and Technical Parameters

4.1. PND500 shaftless pay-off stand:

4.1.1. Of pintle type on end-shaft, the stand is capable of moving up and down both simultaneously and separately to ensure the adjustment of height. Two stanchions move left and right separately, and there is protection against over-twist for loading and limit for unloading. Pay-off tension is controlled by means of mechanical friction and is adjustable.

4.1.2. Bobbin size applicable: PND500

 

4.2. Stranding Cages for 6-bobbin, 12-bobbin and 18-bobbin

4.2.1. Stranding cage is driven by gearbox via ground shaft and performs forward, reverse and free-load running by operating the hand lever.

4.2.2. After bobbins are loaded, they are clamped with pintle of worm and worm-gear. After the bobbins are fixed, the clamping device is self-locked to ensure safety during production.

4.2.3. Bobbin tension is controlled by means of mechanical friction and adjustable by hand.

4.2.4. Bobbin size applicable: PND500

 

4.3. Closing die holder & pressing holder

4.3.1. One group of closing die holder and roller pressing die is fixed behind each stranding cage with the closing die holder adjustable from the front or the behind.

4.3.2. Closing die holder can achieve wires closing or drawing and pressing into cables.

 

4.4. Length Counter

4.4.1. Of roller contact type. Both photoelectric and mechanical modes make length counting more accurate.

 

4.5. Main Transmission System: 36-stage gearbox device

4.5.1. Main transmission system is provided with a DC motor, and gearbox has toughened face gears to ensure accuracy.  

 

4.6.φ2000 Dual Haul-off Device

4.6.1.φ2000 mm dual haul-off device is provided with dual motorization and dual haul-off featuring good synchronous performance and large haul-off.

 

4.7. φ2500 Shaftless Type Take-up & Traversing Stand

4.7.1. The stand is provided with electric elevation to clamp the bobbin, with limit guide and reliable performance.

4.7.2. Take-up device is driven by torque motor via a gearbox.

4.7.3. Bobbin size applicable: PN1600-PN2500

 

4.8. Electrical Control System

4.8.1 Composed of

Control for the main machine, control for take-up and traverse, control for auxiliary units and PLC system. The control system is advanced, reliable in performance, provided with complete protection measures, and easy in operation.

 

Power supply is of three-phase five-line system, 380V (±10%), 50Hz, and single-phase control voltage is at 220V.

 

4.8.2 DC Speed Regulator

   Fully digital DC speed regulator is used for the main machine, so start and stop process is controlled by PLC. The main machine, take-up and traverse automatically follow each other in speed.

 

4.8.3 Man-machine Interface System

   PLC, industrial grade man-machine interface and external input and output interface perform monitoring and inspection over the machine, as well as breakdown indication, provided with complete monitoring, measuring and indicating systems. Running condition is displayed in the man-machine interface, with pages accessible as per actual situation.
