Galvanized Steel Wire Drawing Die

Galvanized steel wire drawing die

The galvanized steel wire drawing die is a mold for drawing various metal wires, which can draw straight, difficult-to-machine objects such as bars, wires, wires, pipes, etc. and is suitable for galvanized steel wire, steel, copper, tungsten, molybdenum and other metals. The drawing process of the alloy material is to obtain a wire with precise wire diameter, good surface quality and high strength. The high temperature resistance, high strength and wear resistance of molybdenum wire make it widely used in electric light source, wire cutting and other industries, but it has the characteristics of high deformation temperature, fast work hardening rate and high tensile strength, so it is difficult to process. The quality of the wire drawing die is very high. The fine molybdenum wire is usually used in the polycrystalline drawing die, which affects the quality of the drawing die. In addition to the core material, it is mainly the hole type parameter of the drawing die. The main parameters of the drawing die are measured by a special wire drawing die tester, and the optimum range of the drawing die hole parameters is compared and analyzed to improve the use quality and working life of the wire drawing die.

With the development of the wire drawing industry, the speed of the wire drawing machine is getting higher and higher. At the same time, in addition to drawing ordinary carbon steel wire, it is necessary to pull hard-to-machine galvanized steel wire. It is reported that the ultra-fine grained carbide drawing die has been applied abroad, not only the quality of the drawn wire is good, but also the die life is doubled compared with the general drawing die. Since last year, we have been paying close attention to this aspect of research, but the conventional fine w powder is made into a fine grained carbide with a high rate of drawing. Therefore, we have developed a composite recycled carbide powder for plating. Study on fine-grained cemented carbide of zinc wire drawing die. It is well known that ordinary YG8 carbide drawing die has been used for many years in China. This alloy has good comprehensive processing and mechanical properties, and the bending strength is also improved while maintaining high hardness. The hardness of fine-grained hard alloys can be increased by 2HRA or even 3HRA compared to the hardness of medium-grain alloys with the same cobalt content. However, the flexural strength is low. How to overcome this problem is the key to this research topic. This study adopts the method of adding alloying elements or carbides to improve the hardness and strength of fine-grained carbide brushing die. Thereby increasing the service life of the wire drawing die.
