I bought a cemented carbide wire drawing die. What everyone is most concerned about is how to operate the standard and how to maintain it to be wear-resistant. Today, I will share with those who have wire drawing dies or want to buy wire drawing dies how to maintain the wire drawing die to be wear-resistant.
After the cemented carbide wire drawing die is used for a period of time, its internal parts will gradually wear out and be damaged, which will reduce the working performance and accuracy of the cemented carbide wire drawing die. Due to the carelessness of the operator and improper maintenance and use, the tungsten steel wire will also be drawn. If the mold is damaged or the product quality is degraded, or even the production is stopped, how to eliminate and avoid these failures requires the cemented carbide mold technicians to master the relevant mold repair technology, so that failures can occur at any time, and they can be dealt with and repaired at any time, so that they can Try to return to normal use as much as possible, and the maximum potential of the mold has been exerted.
In order to improve the service life of cemented carbide wire drawing dies, the following points should be paid attention to in the selection and use process:
1. Choose mold grades reasonably
According to the physical and mechanical properties of the material and the size of the material, choose the mold grade reasonably. For example, if the tensile diameter is less than 20mm, choose YG6 or YG8 for non-ferrous metal wire or bar; choose YG8 for 20-50mm; choose YG11, YG15 for 50mm or more.
2, check the wire drawing machine in time
3, clean the wire properly
Before wire drawing, the surface of the wire must be properly cleaned, otherwise it will easily reduce the service life of the mold, and it will also easily cause scratches on the wire, which will affect the surface quality.
4. Choose the right lubricant
Use high-quality lubricants, such as wire drawing powder, to increase the service life of the wire drawing die.
5. Lubrication protection
Cool the cemented carbide dies well, and lubricate the working area, especially the high-speed wire drawing dies, so as to improve the service life of the wire drawing dies.
6. Choose a reasonable compression rate
A reasonable compression rate should be selected according to the size and performance of the wire to be drawn. If the compression rate is too small, the production cost will be too high; if the compression rate is too large, the service life of the mold will be reduced, or even the mold will be exploded.
7, pay attention to control the surface condition of metal materials
During the drawing process, if metal particles are found adhered to the inner hole of the mold, and the metal surface is scratched, the machine should be shut down immediately to remove the adhered metal particles and polish the inner hole of the mold. The metal particles adhering to the inner hole must be carefully cleaned after each use.
8. Regular inspection of molds
Inspect the mold regularly to find the metal particles adhering to the inner hole in time
9. Keep the mold properly
Keep the drawing dies properly, and apply anti-rust oil for protection if they are not used temporarily.
