Uniformity Wire Cemented Carbide Die Drawing In A Very Efficiency
Speed Save Time
The thread wire drawing dies with three, four and six ribs are
divided into left and right rotation. The lead is processed
according to international or customer requirements. They are used
in the drawing of pretressed spiral steel wire and decorative
spiral. The spiral ribs are uniform and have high bonding strength
with cement. Their properties are superior to those of cold rolled
ribbed steel bars. Wire wires are widely used in highways and
airports.

Notice:
When using the carbide drawing die, we should pay attention to five
points: equipment selection, wire material pretreatment, selection
of appropriate lubricant, abnormal treatment, aging and timely
replacement.
1. Equipment selection: According to the material you want to draw
and drawing equipment, reasonable proportion of the compression
ratio of each drawing die, so as to determine the angle of each
drawing die workspace. (which type of wire drawing die) should be
chosen?
2. pretreatment of wire drawing materials, such as cleaning, rust
removal, annealing, phosphating and so on, to ensure the
cleanliness of materials.
3. Wire drawing powder, oil selection: select high-quality suitable
wire drawing powder (lubricant, oil), do a good job of cooling wire
drawing die.
4. Disposal of abnormal dies in time: If die cracking, die
explosion, die sticking, scratching, shrinkage, broken wire, high
temperature, die blackening, non-wear-resistant and other use
problems, please contact professional and technical personnel in
time.
5. Timely replacement of aging drawing die: When the drawing die
reaches the service life, please change the drawing die to repair
the die in time, so as to avoid the scrap of drawing material
caused by excessive use of drawing die.
