Wire drawing die is widely used, such as high-precision wire used in electronic equipment, radar, television, instrumentation, and commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable, and various alloy wires. The wire drawing die is made of natural diamond, which has strong wear resistance and long service life. Wire drawing die manufacturers include multiple process steps when producing wire drawing die inserts, such as stamping, wire drawing and turning.

With the rapid development of industrial molds, the use of hard alloy workpieces for wire drawing die is more and more common, and its electrical discharge machining stability can improve the accuracy of molds with more complex shapes. The production process of wire drawing die is the key to each process, which will directly affect the quality and performance of the cemented carbide die. It is more important to analyze the cause of wire drawing die damage.
When wire drawing die parts, the coarse wire drawing machine has a very important role in drawing thin wires or wires or wires. Even if the wire or wire is used after the original diameter of the cold drawn wire, it becomes a die or wire. The phenomenon of wire drawing die is usually caused by repeated use of the wire drawing die, so it is necessary to analyze the cause of the damage of the wire drawing die to avoid damage and effectively prolong its service life. Let's take a look together.
1. The wire drawing die blank and the tool steel socket are asymmetrical, and the uneven distribution of the alloy steel jacket or the gap easily leads to cracks in the U-shaped wire drawing process.
2. In the wire drawing die blank using the laser drilling process, the sintering is clean and dirty or the heat is uneven, so that the metal catalyst of the diamond layer is combined into a pile or similar traces, so it is easy to cause die pits during processing.
3. The design of the wire drawing die hole is unreasonable, the lubrication inlet area is too small, and the setting area is too long, which will lead to poor lubrication, end breakage and even die wear.
After finding out the reasons for the damage of the wire drawing die, and formulating corresponding countermeasures according to these reasons, it can effectively prolong the service life of the wire drawing die, reduce the damage during use, reduce the production cost and improve the work efficiency.
