Carbide Drawing Die and PCD Polycrystalline Diamond Drawing Dies
The wire drawing die made of polycrystalline diamond has good wear resistance,uniform inner hole wear,strong impact resistance and high drawing power.
Compared with cemented carbide,the tensile strength of PCD is only 70% of common cemented carbide,but the hardness is 2.5 times of cemented carbide.
In this way,pcd wire drawing dies diamond drawing dies has more advantages than cemented Carbide Drawing Die.
The wire drawing die of polycrystalline diamond dies has the following obvious advantages
1.Good wear resistance and long service life.The service life of Polycrystalline Diamond Drawing Die is about 30 ~ 50 times as long as that of cemented carbide drawing die,so there is no need to stop the machine frequently to replace the die in the drawing process.The change of hole diameter of polycrystalline drawing die in unit time is very small,and the change of wire size is very small,which is very beneficial to the winding of reel.
Generally, the number of winding turns of drawn wire is fixed.If the scale of wire product becomes larger quickly,the number of winding turns will be reduced rapidly,so the scale of reel needs to be changed constantly,which is not conducive to the improvement of production power.
2.High drawing power.The necessary maintenance of the pcd wire die in the process of use is very important for the service life of the drawing die and the surface quality of the wire rod.It is generally recommended that customers maintain the PCD Wire Drawing Die every 24 hours.In 24 hours,the change of hole diameter of polycrystalline diamond wire die is small,and the change rate of wire diameter is also small.
For the whole production process, the wire diameter compression ratio of each drawing die is relatively stable,and the ratio of input and output is large.
3.Save raw materials.If the drawing surface is coated with metal wire,the electroplating process does not stop in the drawing process,which leads to the plating thickness on the surface of the wire being electroplated is too thick.When the drawing is started again,the wire with too thick thickness needs to be cut off,forming a great waste.The more times the machine stops,the greater the waste.Choosing polycrystalline diamond drawing dies can greatly reduce this waste.
4.Reduce labor intensity.Due to the long service life of polycrystalline diamond pcd die and slow number expansion,there is no need to replace the die frequently.Unlike cemented carbide drawing die,it is necessary to pay attention to the change of wire size at all times,which greatly reduces the labor intensity of workers.A worker can co-ordinate 4-5 wire drawing machines in the production process.
Therefore,pcd polycrystalline diamond dies has been paid more and more attention in metal wire drawing dies industry.
