How to Increase the Service Life of Wire Drawing Dies?
Wire drawing die is a very important consumable product for wire drawing by various metal wire manufacturers. Many people complain that the carbide wire drawing dies are not wear-resistant and lead to a series of problems in the drawing process. Therefore, how to reduce the consumption cost of the wire drawing dies and increase their service life is the primary problem that metal wire manufacturers urgently need to solve. Today, I will share the eight main points about improving the life of TC dies.
Top 7 ways for increasing the service life of carbide drawing dies
- Reasonable choice of grade for wire dies.
- According to the physical and mechanical properties of the drawn material and the size of the material, a reasonable choice of cemented carbide drawing dies grades. For example, in the case of drawing low-carbon steel, YG6 or YG8 should be selected. When drawing high-carbon steel wire, YG6X grade should be used.
- Check the wire drawing machine carefully
- Check whether the drawing machine is stable before drawing, and there must be no vibration phenomenon, otherwise, the drawing die may be easily damaged.
- Do proper cleaning of the wire
- The surface of the wire must be properly cleaned and dried before drawing, otherwise, it will easily reduce the service life of the mold, and the surface of the wire may also cause scratches and affect the surface finish. For wires with excessive hardness or uneven hardness, it should be hardness reduced by annealing or tempering, and elongated to maintain good hardness uniformity.
- Choose the correct lubricant
- Select a lubricant with excellent lubrication performance, such as wire drawing lubricant powder, etc., to maximize the lifespan of the drawing dies. Use a lubricant to carry out good cooling, reduce friction and do a good job of lubrication in the working area, especially when drawing at high speed, it makes great help.
- Reasonable choice of compression ratio
- Choose the appropriate compression rate according to the size and performance of the drawn wire. If the compression rate is too small, it will increase the production cost. If too high, it will reduce the life of the mold and even result in a mold breakage. For example, the single-face shrinkage rate is generally not more than 20% for drawing stainless steel wire.
- Check the wire drawing die regularly
- During the drawing process, if it is found that the metal particles adhere to the inner hole of the core, and the scratches are formed on the surface of the metal material, we should stop drawing immediately, remove the adhered metal particles, and polish the inner hole. The most reasonable method is to do regular inspections without waiting for metal particles to appear on the wall of the inner hole.
- Maintenance of drawing dies
- Anti-rust oil should be used to protect the temporarily unused TC drawing dies.
