Steel mold
The materials used to make steel molds are mainly carbon tool steel and alloy tool steel. Due to the poor hardness and abrasion resistance and short life of steel molds, they have long been replaced by other molds.
Natural diamond (nc) mold
Natural diamonds are the earliest use of wire drawing mold materials in the world. The quality of the pull -up line has gradually become popular in the 1960s. Because natural diamond is expensive, it is only used to make small diameter molds.
Hard alloy model
Hard alloys entered the market in the early 20th century. By the 1950s, they replaced the softer steel molds. Its production technology continued to be updated and quality continued to improve, becoming the main material in the wire industry. Hard alloys are produced by powder metallurgical, which are synthesized by carbides (tungsten, titanium) and melting agent. The less the amount of drilling in the drawing mold, the harder the mold texture, but too little molds will become crispy. In addition, the thinner tungsten carbide particles, the higher the hardness.
Artificial polycrystalline diamond (pcd) mode
Artificial polycrystalline diamond is made of artificial diamond particles and metal melting cobalt molten under high temperature and high pressure. The mass alloy mold is 50 ~ 500 times long, and has good wear resistance and the maintenance of the mold hole circles, strong anti -tensile capacity, low mold cost, and the quality of the wires made by the pull -made wires. Quality alloys, especially in the process of continuous high -speed brushes, show their superiority. However, the domestic polycrystalline diamond has a large porosity, and the surface roughness value of the inner pores of the diamond wire drawing die finished product is high.
Ceramics
In recent years, ceramic brushes have been launched in japan, and its cost is much lower than the artificial polycrystal mold. Although this drawing model is not important during the pull -up process, it plays an important role in the tightness, twisted and guided processes of twisted machines and machines.
Surface enhancement
Because natural diamonds and excellent artificial polycrystalline diamond prices are much higher than hard alloy, people have used various means to change the alloy composition on the surface of the hard alloy wire drawing mold holes and the structure of the hard alloy drawing model, which improves its life span , to the need for high -speed drawing.
What is a diamond wire drawing die
The diamond wire drawing die refers to a tool that forces the diamond through the die under the action of external force during the diamond press processing, and the diamond cross-sectional area is compressed, and the required cross-sectional area shape and size are obtained.
Methods to improve the service life of diamond wire drawing dies
Maintain a suitable drawing surface shrinkage rate
The diamond wire drawing die itself has the characteristics of being hard and brittle. If it is used for the reduced diameter drawing with a large area shrinkage rate, it will easily lead to the stress that the die can withstand and be broken and scrapped. Therefore, according to the different mechanical properties of the wire, select the appropriate area shrinkage for drawing.The stainless steel wire is drawn with a diamond die, and generally the single-pass surface shrinkage rate does not exceed 20%.
Use lubricants with good lubricating properties
In the stretching process, the quality of lubricant and the supply of lubricant affect the service life of the drawing die. Therefore, the lubricant is required to have a stable oil base, good oxidation resistance, excellent lubricity, cooling and cleaning properties, and always maintain the best lubrication state throughout the production process, so as to form a film that can withstand high pressure without being damaged, reduce the friction in the working area and increase the service life of the mold. During use, the condition of the lubricating oil should be continuously observed. If severe discoloration or increase of metal powder in the lubricating oil is found, it should be replaced or filtered in time to avoid the lubricating performance of the lubricating oil from being degraded due to oxidation. At the same time, the fine metal particles falling off during the drawing process are prevented from damaging the diamond wire drawing die.
Regular maintenance and grinding of diamond wire drawing dies
In the process of long-term use of the wire drawing die, the die wall is strongly rubbed and scoured by the metal wire, which will inevitably produce abrasion. The most common one is the annular groove (dent) at the wire entrance in the working area. The appearance of the ring groove of the drawing die has aggravated the wear of the die hole, because the small particles of the core material peeled off due to the loosening of the ring groove are brought into the working area and the sizing area of the die hole by the metal wire, acting as an abrasive, and entering the wire of the die hole increases the wear of the die hole like a grinding pin. If it is not replaced in time for repair, the ring groove will continue to accelerate and expand, making repair more difficult, and there may even be cracks in the deeper part of the ring groove, causing the diamond wire drawing die to be completely broken and scrapped.

Reasons and Analysis of Wear of Diamond Wire Drawing Die
The processing quality of the diamond wire drawing die itself leads to die wear
(1) The asymmetrical inlay of the diamond die blank and the die steel sleeve, and the uneven distribution or gaps of the sintered cemented carbide steel sleeve can easily lead to u-shaped cracks during wire drawing;
(2) During the laser drilling process of the diamond die blank, the sintering traces are not cleaned or unevenly heated, which will cause the metal catalysts and bonding agents in the diamond layer to gather together, which will easily lead to pits in the diamond wire drawing die during the wire drawing process；
(3) The mold hole design is unreasonable, the inlet lubrication area opening is too small, and the setting area is too long, which will cause poor lubrication, resulting in mold wear and even chipping.
Improper use in the drawing process leads to the wear of diamond wire drawing dies
(1) The drawing surface shrinkage is too large, causing cracks or breakage of the diamond wire drawing die. Most of the cracks or broken cracks are caused by the release of internal stress. In any material structure, the existence of internal stress is inevitable. The internal stress generated during wire drawing can enhance the diamond microcrystalline structure, but when the drawing surface shrinkage is too large, it cannot be lubricated in time, and the temperature rise will cause part of the material on the surface of the diamond wire drawing dies to be removed, and the stress on the microcrystalline structure will greatly increase, making it easier to crack or break.
(2) The drawing axis of the wire rod is asymmetrical with the center line of the die hole, resulting in uneven stress on the wire rod and the wire drawing die, and the impact generated by mechanical vibration will also cause high stress peaks on the wire rod and the drawing wire die, both of which will accelerate the wear of dies.
(3) Factors such as uneven wire hardness caused by uneven annealing can easily cause premature fatigue damage to the diamond wire drawing die, forming annular grooves, and aggravating die hole wear.
(4) The wire surface is rough, and the surface adhesion of oxide layer, sand or other impurities will cause the dies to wear out too quickly. When the wire passes through the die hole, the hard and brittle oxide layer and other adhering impurities will cause the wire drawing die hole to wear quickly and scratch the wire surface like abrasives.
(5) Poor lubrication or the lubricating oil contains metal debris and impurities that cause mold wear. Poor lubrication will cause the surface temperature of the diamond die hole to rise too fast during wire drawing, and the diamond grains will fall off, resulting in damage to the die. When the lubricating oil is not clean, especially when it contains metal chips that fall off during drawing, it is very easy to scratch the surface of the mold and the wire.
