Production of tungsten carbide button
Fabrication die for cemented carbide ball teeth
The manufacturing process of the tungsten carbide button is due to the high pressure and repeated friction of the female die during the pressing process, which requires high hardness and good wear resistance. Therefore, YG8 tungsten carbide is used to grind the inner hole of the steel sleeve, and then The steel sleeve is placed in a furnace and heated to an appropriate temperature, and then taken out and quickly embedded in the alloy mold body. 4. Finely grind the outer circle and plane of the steel sleeve to the design size of the female mold, and remove the mandrel. 5. Finely grind the negative model cavity to the designed size. During the pressing process, the upper and lower die punches have good impact resistance and a certain degree of wear resistance. Due to the large elastic modulus of steel and easy sticky materials, the YG20 alloy with high degree of selection is used. The upper and lower die punching process is as follows: 1, l8 is made separately.

Jinxin tungsten carbide button
Jinxin tungsten carbide button,With the development of the petroleum industry, the demand for oil well drilling tools has also greatly increased, with cemented carbide balls particularly prominent. Jinxin tungsten carbide button such as
As shown in Figure 1, its one end is a ball head (the mold cavity is retracted, the upper die punchJinxin tungsten carbide buttones down into the female die; 2. After the upper die punch is compressed to a certain stroke, it is lowered together to press the powder once; 3. The female die is lowered to After setting the position, it stops and the upper die punch continues to descend.
Achieve final compaction by secondary compaction; 4. The upper mold rises, the female mold descends to the position where the compact can freely come out; 5. The upper mold punches and the female mold reset, and returns to the original powder position. During the pressing process, the pressing strokes of the female die and the upper die can be adjusted to adjust the density of the upper and lower ends of the pressed blank accordingly.

Application for tungsten carbide ball
Tungsten carbide balls are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves and flow meters. These balls are also used for coining and
