A wire drawing die is a metal wire passing through a die to make it from thick to thin and gradually reach the size that people need. This special die is a wire drawing die. The mold core of the drawing die is generally made of natural diamonds and artificial diamonds (man-made diamonds include ge, pcd, synthetic materials, etc.). The copper wire drawing die belongs to the soft wire drawing die. There are also hard wire drawing dies, such as drawing tungsten wire and so on. The angle of the compression area of the copper wire drawing die is generally 16-18 degrees, and the sizing length is 30-40%, while the angle of the compression area of the tungsten wire drawing die is relatively small, generally 12-14 degrees, and the fixed line length is 60-70%. %.
Application industry:
wire drawing die is a very important consumable product for various metal wire manufacturers to draw wire. The scope of application of wire drawing dies is very wide, mainly used for drawing rods, wires, wires, pipes and other linear difficult-to-machine objects. . 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 improve its service life is the primary problem that the metal wire production unit urgently needs to solve.
Wire drawing dies are widely used, such as high-precision wire used in electronic devices, radar, television, instrumentation and aerospace, as well as commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and various alloy wires are made of diamond. The diamond wire drawing die is mainly made of natural diamond as the raw material, so it has strong wear resistance and a very long service life.
Drawing dies include diamond drawing dies, carbide drawing dies, plastic drawing dies, and so on. There are many more uses.
