Polycrystalline wire drawing dies have a wide range of uses, such as high-precision wires used in electronic devices, radar, television, instrumentation and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires and various alloy wires are all drawn with diamond The diamond wire drawing die is made of natural diamond, so it has strong wear resistance and extremely long service life. The production process of wire drawing die inserts includes several process steps such as pressing die, drawing die, and turning.
Polycrystalline wire drawing die is a kind of die to make the metal wire from thick to thin, gradually reaching the size that people need. This special die is the wire drawing die. The core of the drawing die is generally made of natural diamonds, artificial diamonds (man-made diamonds include ge, pcd, synthetic materials, etc.). Copper wire drawing die belongs to flexible wire drawing die. There are also hard wire drawing dies, such as drawing tungsten wires. The angle of the compression zone of the copper wire drawing die is generally 16-18 degrees, and the sizing length is 30-40%, while the angle of the compression zone of the tungsten wire drawing die is relatively small, generally 12-14 degrees, and the fixed line length is 60-70. %.
Polycrystalline drawing dies include diamond drawing dies, cemented carbide drawing dies, plastic drawing dies and so on. There are many more uses.
Application industry:
Polycrystalline wire drawing die is a very important consumable product used by various metal wire manufacturers to draw wires. The application range of wire drawing dies is very wide, mainly used for drawing straight and difficult-to-machine objects such as bars, wires, wires, pipes, etc., and generally suitable for drawing processing operations of metal and alloy materials such as steel, copper, tungsten, molybdenum, etc. . Since the cost of the wire drawing die can reach more than 1/2 of the wire drawing cost, how to reduce the consumption cost of the wire drawing die and increase its service life is the primary problem that metal wire production units urgently need to solve.
Polycrystalline wire drawing dies are widely used, such as high-precision wires used in electronic devices, radar, television, instrumentation and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires, and various alloy wires. It is made of diamond wire drawing die. The diamond wire drawing die mainly uses natural diamond as the raw material, so it has strong wear resistance and very long service life.
