About the wire drawing die
Wire drawing dies are commonly used to reduce the diameter of various ferrous and non-ferrous rods and wires. Applications include various grades of low, medium and high carbon steels, steel alloys, stainless steel, welding wire as well as various non-ferrous rods and wires.
Types of wire drawing die
| Type | Material | Performance | Usage | Application Status |
| Alloy steel dies | carbon tool steel and alloy tool steel | poor hardness, wear resistance, short life | eliminated | |
| Cemented carbide dies | the ctungsten-cobalt alloy | high wear resistance, good polishing, low adhesion, low friction coefficient, low energy consumption, and high corrosion resistance | widely used | |
| Natural diamond dies | allotrope of carbon | high hardness and good wear resistance, brittle, difficult to process, expensive | wire diameter of less than 1.2 mm | not the ultimately seek |
| Polycrystalline diamond dies | high-quality artificial diamond single crystals with a small amount of silicon, titanium, other binders | good wear resistance, uniform wear of the inner hole, strong impact resistance, high wire drawing efficiency | widely used | |
| CVD diamond dies | coat diamond film on cemented carbide wire drawing dies, Diamond film is pure diamond polycrystal | smoothness, temperature resistance, wear resistance, low price | bring new vitality to the wire drawing die industry | |
| Ceramic dies | Al2O3/TiC/Mo/Ni ceramic composites | high hardness, good wear resistance, strong chemical stability, excellent high-temperature mechanical properties, not easy to bond with metals | processing of difficult-to-process materials | widely used |
| Tungsten carbide wire drawing dies | medium grain size tungsten carbide powder with 6-13% cobalt binder | toughness and resistance to fracture | draw larger diameter wires with heavy reduction | widely used |
Key points for use of wire drawing die
In order to ensure high-quality wire and effectively control the cost of using the die, the following points should be noted when using the wire drawing die:
Ensure the smooth operation of the wire drawing equipment: each wire drawing drum wheel and wire guide wheel should be smooth and flexible, and its runout tolerance should be strictly controlled. If the drum wheel and guide wheel are found to have wear grooves, they should be repaired in time.
Good lubrication conditions are important conditions for ensuring the surface quality of the wire and extending the life of the die. The lubrication index should be checked regularly, and the copper powder and impurities in the lubricating oil should be removed so that it does not pollute the equipment and die holes. If the lubrication fails, it should be replaced in time and the lubrication system should be cleaned.
Reasonable die matching is the key factor to ensure the surface quality of the wire, control the size accurately and consistently, reduce the wear of the wire drawing drum wheel, and reduce the operating load of the equipment. For sliding wire drawing machines, it is the first step to match the die to be familiar with the mechanical elongation of the equipment and reasonably select the sliding coefficient.
Select the die hole type according to the material of the wire being drawn and the surface reduction rate of each wire drawing. Generally speaking, the harder the wire being drawn, the smaller the compression angle of the die and the longer the sizing area; vice versa. The area reduction rate of each wire drawing is also closely related to the compression angle of the corresponding die. The size of the compression angle should be appropriately adjusted according to the size of the area reduction rate.
