Drawing die structure and material selection 1.1 Drawing die core structure and function. According to the working nature of the wire drawing die core, it is usually divided into five areas, namely the entrance area, the lubrication area, the working area, the sizing area, and the exit area. Friction with the wire drawing die; Lubrication area: Use lubricant to increase the lubricity of the wire; Working area: It is the key part of the die hole.

What is the method to prolong the service life of diamond wire drawing dies? Diamond wire drawing dies are not only a production tool in the cable industry, but also an important role in the fine wire industry. Its purchase price is very expensive. How can we improve its service life after purchase? We should choose some high-quality wire drawing dies as much as possible. The production process of this product in China is all high-speed mechanical grinding machines, and the grinding needles with a layer of diamond on the surface are also used. Such equipment is very stable during operation, and the specifications for the use of grinding needles are very standardized, and the product precision it brings is also very high. However, many domestic manufacturers are backward in production technology, mainly using manual methods to flood the hole pattern on the product, so that the hole pattern fluctuates greatly in parameters, and it is not easy to reach us after processing. requirements in the project. In addition, domestic products are relatively backward in terms of detection methods, and can only be detected by a simple method such as a magnifying glass or visual inspection, but the inner film finish and size of the product cannot be well detected. If we want to make the service life of the diamond wire drawing die longer, then we should pay attention to rationalization when installing and using the product. When applying it, you should pay attention to a stable installation foundation and try to avoid vibration problems. And in the process of our installation, we should also make a uniform force between the wire drawing die and the wire. In the process of pulling the wire, it is necessary to avoid frequent parking and starting the car as much as possible, otherwise it is easy to cause damage to the product.
