In metal pressure processing. Under the action of external force, the metal is forced to pass through the mold, the cross-sectional area of the metal is compressed, and the thing that obtains the required cross-sectional area shape and size is called a wire drawing die.
Wire drawing die are widely used, such as high-precision wires used in electronic devices, radar, television, appearance and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wires and cables, and various alloy wires. The manufactured diamond wire drawing die has strong wear resistance and extremely long service life because it uses natural diamond as the material. The production technology of wire drawing die inserts includes several technical steps such as pressing die, drawing die, and turning.
The drawing die is where the metal wire passes through a mold to gradually reach the scale you need from thick to thin. This special mold is the drawing die. The core of the drawing die is usually made of natural diamonds, artificial diamonds (artificial diamonds). Diamonds include GE, PCD, composition materials, etc.). Copper wire drawing die are classified as soft wire drawing die. There are also hard wire drawing die, such as drawing tungsten wires. The viewpoint of the compression zone of copper wire drawing die is usually 16-18 degrees, The fixed diameter length is 30-40%, while the viewpoint of the tungsten wire drawing die shrinking zone is relatively small, usually at 12-14 degrees, and the fixed line length is 60-70%.
The wire drawing die include diamond wire drawing die, cemented carbide wire drawing die, plastic wire drawing die, and so on. There are many more uses.
