Factory Tungsten Carbide Spiral Screw Wire Drawing Dies

Tungsten carbide drawing die, usually any kind of drawing wire die. Tungsten carbide drawing dies have a hole in the center of a shape, round, square, octagonal or other special shape. The metal becomes smaller and even changes shape as it is pulled through the die hole. The drawing die is widely used. The drawing die reaches the required shape of the product through stretching forming. Stretching is to deform the plate metal material into cylindrical or box shape parts by stamping, ring pulling or metal mold process.

The function of each part for carbide drawing die:

1, The entrance area: 

from the entrance area to the working area is generally an arc transition, easy to import wire smoothly, and convenient for drawing lubricant rotation;

2, Lubrication zone: 

to lubricate the drawing material, so that the wire easily transition;  

3, Compression zone: 

Linear working area can reduce drawing resistance, change point contact to surface contact, reduce friction and die wear, deformation structure is more reasonable and stable. The feed line becomes thick or thin can be pulled smoothly;  

4, Sizing area: 

linear sizing area can ensure the precise diameter and finish of the wire;  

5, Safety angle: 

safety Angle can ensure that the wire is pulled out without scars, to ensure the quality of the wire;  

6, The export area: 

export area can ensure smooth wire
