Tungsten Carbide Nozzle for BOSCH making motor stator 1.3-0.2-20

Winding Coil Carbide Nozzle

The tungsten carbide nozzle used in coil winding machine to guide the wire to wind on the bobbin ,

on the pins and etc .for the manufacture of coils ,motor transformers ,relays ,contactor ,inducance

and sensors in automotive ,telecoms ,electric and electronic application .

Description :

The Carbide Winding nozzle is precisely processed from ultrafine particle tungsten carbide ,the hardness is up to above HRA90 degree ,and the bending strength is more than 2300N/mm ,QIANHE uses special equipment for precision abrasive machining and precision grinding treatment of inner hole to make the roughness reach up to Ra0.1,and the roughness of R at both ends are up to Ra0.025,The curvature radiuse of the inlet and outlet two ends are scientifically desighed to ensure that the wires pass smoothly and naturally .There is no step inside hole of the wire guide nozzle ,thus improving the phenomenon of easy bending and blocking .

Aplication :
The Tungsten Carbide Nozzle is mainly used on full-automatic winding machine for high-speed

winding of fine coils and super fine enameled wires

Key advantages of Tungsten Carbide Nozzle :

1. High Wear Resistance

This is assured by the choice of materials for wear elements possessing. Hardness

Value: 1800 ~ 2200Vickers, or 3times that of case hardened steel. Body material is stainless

steel for structural supports, not wear-bearing.

2. Scratch-Proofing

Eliminate wire insulation film damage, low friction resistance, stable wire tension.

The wireguiding surfaces are mirror finished by diamond lapping to a surface roughness of

2 4 micro inches Ra or better, material permit.
3. Straightness and Stiffness

Straightness and Stiffness are defined by the wire exit being concentric and inflexible

with respect to the nozzle locating. In plain terms, the wire should exit from the nozzle

concentric to the locating, To within 0.02 mm, with or without load. A geometric

Characteristic presentation is shown at upper left. Concentricity to within 0.01mm.
4. Precise Exit Radii

Because the coil winding nozzle's Exit Radii governs the angle of the wire exit from one

coil to the next, it should be monitored to + / - 0.025 mm. This is done by digital measurement,

shown at upper right.
