How to prolong the service life of PCD wire drawing dies?

Diamond drawing die is made of natural diamond, which has a strong wear resistance and long service life. Because the price of natural diamond drawing die is the most expensive, the processing is also extremely difficult. As a result, a number of new substitutes have emerged. For example, polycrystalline diamond wire drawing dies. then, how to prolong the service life of PCD wire drawing dies?

The methods for improving the service life of drawing dies:

In order to prolong the service life of the drawing die, it is necessary to select the suitable die material, design the reasonable pass size, improve the manufacturing level of the drawing die, and make the surface finish of the die meet the technological requirements, it is also necessary to determine the reasonable drawing surface shrinkage and improve the service conditions of the drawing die. Pay attention to the daily maintenance of the mold in the use process, wash and replace frequently, and ensure a good lubrication effect in the drawing process.

Similarly, for the drawing machine, we should pay attention to the following matters:

  • The installation foundation of the wire drawing machine should be very stable to avoid vibration;
  • During installation, the drawing axis of the wire rod should be symmetrical with the center line of the die hole through debugging, so that the stress of the wire rod and the drawing die can be even;
  • Avoid frequent starting and stopping during the drawing process, because the friction caused by the tensile stress at the beginning of drawing is much larger than that during normal drawing, which will increase the wear of the die.

In addition to PCD drawing die, Our carbide wire drawing die has also been recognized by domestic and foreign customers. In addition, Our also provides cold roller and hot mill roller for rolling steel bars, nail making tools and other wire tools. At the same time, Our has a variety of advanced production equipment, a group of the professional technical team, can provide customers with customized carbide OEM services to meet the personalized needs of customers.
