Tungsten carbide wire drawing die is an important die for the production of metal wire. Its quality directly affects the quality of the wire, the loss of die and the economic benefit of product production. In the quality of tungsten carbide drawing die, except the material of die core, the perpendicularity of the die hole center and the die outlet, the pass structure of die hole is an extremely critical factor affecting the quality of tungsten carbide wire drawing die. The key parameters of tungsten carbide wire drawing die quality are the structure of die hole and the size of each part. This requires the mold in the production process, the producer should grasp these parameters in time, in order to carry out the necessary grinding correction, so as to improve product quality. In order to improve the service life of tungsten carbide wire drawing die, the following points should be paid attention to in the selection and use process.
1. Rationally select grade of tungsten carbide wire drawing die
According to the physical and mechanical properties of the material and the size of the material, rationally select grade of tungsten carbide wire drawing die. For example, YG6 or YG8 should select for steel bar, non-ferrous metal wire or bar with tensile diameter below 20mm, Choose YG8 for 20-50mm, Choose YG11 and YG15 for above 50mm.
2. Timely check the drawing machine
3. Properly clean the wires
The surface of wire rod should be cleaned properly before drawing, otherwise it is easy to reduce the service life of the tungsten carbide wire drawing die, and also easy to produce scratches on the wire rod, affecting the surface quality.
4. Choose the right lubricant
To choose high-quality lubricant, such as: drawing powder, in order to improve the service life of tungsten carbide wire drawing die.
6. Reasonable choice of compression rate
According to the size and performance of the cable to choose a reasonable compression rate, compression rate choice is too small, resulting in high production costs, If the compression ratio is too large, the service life of the tungsten carbide wire drawing die will be reduced, or even die.
7. Pay attention to control the surface condition of metal materials
In the drawing process, if it is found that metal particles adhered to the inner hole of the mold, and the metal surface should be scratched, stop immediately, remove the adhered metal particles, and polish the inner hole of the mold. The metal particles adhered to the inner hole should be carefully cleaned for each use.
8. Check the tungsten carbide wire drawing die regularly
Check the tungsten carbide wire drawing die regularly to find the metal particles sticking to the inner hole in time.
