Advantages of diamond drawing die

Compared with other wire drawing dies, the tensile strength of diamond wire drawing dies is only 70% of commonly used cemented carbide, but its hardness is 2.5 times that of cemented carbide. This makes the diamond drawing die have more advantages than other molds. Diamond wire drawing die has good wear resistance, uniform inner hole wear, strong impact resistance, high drawing efficiency. Therefore, diamond wire drawing die is gradually receiving attention in the metal drawing industry.

Compared with other dies, the use of diamond wire drawing dies has the following obvious advantages:

1. save raw materials. If the wire is plated on the drawing surface, the plating process will stop and will not stop during the drawing process, which will lead to an increase in the thickness of the electroplating on the plating surface and a thickness that exceeds the required standard when drawing again. But cutting it creates a lot of waste, and the longer the downtime, the greater the waste. The use of diamond drawing die can greatly reduce this waste.

2. Reduce labor intensity. Due to the long life of the diamond wire drawing die, slow expansion, no need to frequently replace the mold, unlike other molds, you must always pay attention to the change of wire diameter, greatly reducing the work intensity of manual and workers, because workers can use 4 to 5 diamond wire drawing dies in the production process.

3. high drawing efficiency. The necessary maintenance during the use of the wire drawing die is very important for the life of the wire drawing die and the surface quality of the line. It is generally recommended that customers maintain diamond drawing dies every 24 hours. Within 24 hours, the aperture of the diamond drawing die changes little, and the rate of change of the wire diameter is relatively small. During the entire production process, the linear compression rate of each drawing die is relatively stable.

4. good wear resistance, long service life. The life of the diamond drawing die is about 30-50 times that of other dies, so there is no need to close frequently to replace the die during the drawing process. The aperture of the diamond wire drawing die changes very little per unit time, and the size of the wire drawing changes very little, which is very favorable for the winding wheel.
