The hole pattern of the wire drawing die is usually circular to ensure the roundness and diameter consistency of the wire and cable. Different metal materials and wire drawing speeds need to choose the appropriate pass angle and aperture ratio to reduce friction and heat during the drawing process and improve the life and performance of the drawing die.
The material of the wire drawing die can be cemented carbide, PCD, nano-diamond, etc., which has the advantages of high hardness, high wear resistance, and high tensile strength. Different materials have different characteristics and scope of application, which need to be selected according to the requirements and cost of wire and cable. Generally speaking, cemented carbide wire drawing dies are suitable for low-speed, low-temperature, and low-pressure wire drawing conditions; PCD wire drawing dies are suitable for high-speed, high-temperature, and high-pressure wire drawing conditions; nano-diamond wire drawing dies are suitable for ultra-high speed, ultra-high temperature, and ultra-high Stressed drawing conditions.
The lubrication method of the wire drawing die can be dry or wet, and the appropriate lubricant should be selected according to different metal materials and wire drawing speeds. The role of the lubricant is to form a layer of lubricating film between the wire drawing die and the metal wire to reduce friction and heat, prolong the life of the wire drawing die and improve the drawing quality. Dry lubricants are usually powder or paste substances, such as soap powder, graphite, etc., and wet lubricants are usually water or oil-based liquids, such as water-soluble oil, emulsified oil, etc.
The management and maintenance of the wire drawing die is an important factor affecting the quality and efficiency of the wire drawing, and requires regular inspection, cleaning, grinding, replacement and other operations. When inspecting, pay attention to observe whether the appearance, hole shape, size, etc. of the wire drawing die are damaged or deformed. When cleaning, pay attention to using suitable cleaning agents and tools to avoid secondary damage or pollution. When grinding, pay attention to using a suitable grinder And the grinding wheel, operate according to the specified procedures and parameters. When replacing, pay attention to record the use and life of the drawing die, and classify and store according to the specified standards.
The wire drawing die for wire and cable is an important industrial product, which plays an important role in improving the quality and efficiency of wire and cable. With the advancement of science and technology and market demand, wire drawing dies for wire and cable are also constantly developing and innovating, bringing more opportunities and challenges to the wire and cable industry.
