Application of the drawing die very extensive, and can be used in the production of a variety of wire, polysilicon cutting wire, steel cord, wire and cable, gas - protection welding wire, flux cored wire, electronic wire, silver, tin, gold, car line, pipeline construction in line, line of rigging, and an optical fiber.
In a variety of industries, such as electronic devices, radar, television, instrument and aerospace high precision wire and commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and all kinds of alloy wire are using diamond wire drawing die drawing, diamond wire drawing die due to the use of natural diamond as raw material, which has very strong wear resistance, the service life is very high.
In metal pressure processing. Under the action of the external force to make the metal through the mold, metal cross-sectional area is compressed, and get the required cross-sectional area of the shape and size of the tool called the wire drawing die. The drawing die is a metal wire through a mold, make it from coarse to fine, and gradually reach the size of the people need, this kind of special mold is the drawing die.
Mould core wire drawing die is generally used in natural diamond, polycrystalline diamond (PCD, CD composite material). Copper wire drawing die is wire drawing die. There are hard wire drawing die, such as tungsten wire pull etc.. Copper wire drawing dies compression zone is generally 16 to 18 degrees, fixed length for 30-40% tungsten wire drawing die compression zone is relatively small, general at 12-14 degrees, line length is 60% to 70%.
