650B double twist bunching machine

Mechanical structure performance analysis:

1. Mechanical body structure:

1-1 Material: low carbon steel welding form

1-2 Structure: the mechanical body is treated by annealing , eliminate stress, precision boring machine through a molding process.

2. Inlet part:

2-1 Inlet location: in the face of machine, on your right (may according to customers requirements and correct to left).

2-2 Way of inlet: from pay-off device pass by wire breakage induction district, first through total sub-panels (hole-line distributed as 1+6+12+) through the first isobar die, and through the second isobar die, at last get into wire guiding round of the right spindle. Through Al-arch belt ceramic ring enter wire guiding round of the left spindle , through center corner round to capstan wheel, after passing by the third isobar die to arrange wire (Details for way of thread diagram).

3. Spindle

3-1 Material: #45 steel slag after quenching and tempering.

3-2 Accuracy: cylindrical core shaft and bearing positioning end are all lapped, ensure that the concentricity of axis core and the vertical degrees.

3-3 Balancing: the accuracy of balancing is G2.5 grade (the variance of weight is 0.03 grams ).

4 Aluminum disk

4-1 Material: ZL104

4-2Accuracy: all cylindrical end relative positioning holes beating 0.03.

4-3 Balancing: the accuracy of balancing is G2.5 grade (the variance of weight is 0.03 grams).

5.Arch belt

5-1 Material: imported Taiwan quality 65Mn heat treatment.

5-2 Shape: special appearance and reduce wind resistance.

5-3 The variance of weight: each variance of weight 0.03 grams.

6.Drive part

Drive by synchronization strap, standard lay length is exact, synchronization strap is adopted imported product.

7.Wire guiding wheel

7-1 Material: #45 steel heat treatment HRC30-40.

7-2 Plating hard chromium or spraying ceramic on surface, not been worn.

8. Spindle housings

8-1 Material: ductile iron QT42-10.

8-2 Processing: CNC machine tools

8-3 Accuracy: inner hole end, a molding process to ensure the concentricity.

9. Bearing spindle lubrication system:

9-1Way of lubrication: flying cheap-oil lubrication

9-2 Model of oil: 46 wear-resistant hydraulic oil

9-3 Way of sealing: mechanical retaining oil ring and back oil hole to prevent oil leakage and maintain internal cleaning of machine.

10. Take-up

10-1 Take-up tension control: take-up tension is controlled by magnetic powder clutch . PLC automatic follow-up and regulate tension, the tension is constant.

11.Dimension of take-up spool






Positioning hole

Center distance








(The above specifications is factory standard specifications, may design according to customers take-up spool size.)

12. Dynamic power:

One 650B high speed bunching machine   3.5KW

13. Static power:

One 650B high speed bunching machine   7.5KW

This kinds of machine is applied to the double twisting of 2 pcs of core wire(telephone wire and network cable).

This machine has been solden to India, Uzbekistan, Egypt and America and enjoy good fame.


1.   Usage: It is applied to the double twisting of  2 pcs of core wire(telephone wire and network cable).

2.Diameter of single core: φ0.5~φ3.0mm

3.Outer diameter of wire: φ1.0~φ6.0mm

4.Size of take up spool: φ630mm×length360mm×inner coreφ80mm

5. Maximum rotating speed: 1600RPM (3200 twist/min)

6.Type of traverse: φ30mm rolling ring traverse,winding pitch and breadth are adjustable.

7. Standard lay length: 34 section 11.15~100mm (enclose list of standard lay length).

8. Main motor: 7.5KW AC motor +frequency converter

9. Weight of copper load: about 3500kg

10. Direction of strand: optional for right or left

11. Brake: electromagnetic brake for external break, automatic stop when wire reach setting meter.

12. Tension control: take up tension is controlled by magnetic powder clutch, PLC follows up and regulates tension ,constant tension.

13. Drive bearing: it is adopted imported Japan bearing.

14. Synchronization strap: it is adopted imported American product.

15. Spool from top to bottom: it is adopted manual pump hydraulic landing.

16. Way of spindle lubrication: splash machine oil lubrication.

17. Index of noise: about 80dB

18.Dimension: (length×breadth×height): 3300×1450×1650

19. Weight: 3500Kg
