CVD coated wire drawing die

The CVD coating wire drawing die has good wear resistance due to the diamond property, and the surface roughness of the drawn wire wire is low, but the CVD coating wire drawing die has a complicated manufacturing process, is difficult to process, and has high cost; when the coating wears After the mold will wear out quickly, it is not only difficult to guarantee the processing quality, but also can not be reused, only scrapped.

(5) CVD (Chemical Vapor Deposition) coated wire drawing die is a newly developed new technology, the main method is to coat the diamond film on the carbide die. The diamond film is a pure diamond polycrystal, which has the advantages of single crystal diamond smoothness, temperature resistance, wear resistance of polycrystalline diamond and low price, and is very good in replacing the rare natural diamond to prepare the drawing die tool. The effect, its widespread use will bring new vitality to the wire drawing industry.

In the drawing process of small wire and wire, natural diamond polycrystalline diamond and CVD coating die are commonly used wire drawing die materials. Their drawing quality comparison is shown in Table 3. When drawing small-diameter wires, the CVD-coated diamond mold overcomes the anisotropy of the natural diamond mold, and has excellent strength and hardness, and the highest surface quality of the drawing yield is also required. The test proves that the life of the CVD coated diamond wire drawing die is equivalent to that of the natural diamond die, and the product yield is high, and the surface quality is superior to the domestic polycrystalline diamond. Therefore, for small diameter wire drawing, CVD coated diamond wire drawing die is an ideal choice. Although the drawing die can be used to process various metal and alloy materials such as steel, copper, tungsten, molybdenum, etc., the drawing die of different materials has its applicable processing range, and the wear form and use of the wire drawing die of different materials when the same wire is processed. There is a big difference in life, so the reasonable selection of the wire drawing material is the key to ensure successful application. Drawing die of different materials has relatively reasonable processing objects. The rationality of the drawing process mainly means that the mechanical, physical and chemical properties of the drawing die and the wire are matched to each other to obtain the longest die life.
