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.
