1.Reasonable selection of mold grades According to the physical and mechanical properties of the drawn material and the size of the material, the grades of cemented carbide molds are reasonably selected. For example, in the case of steel bars with a diameter of less than 20.0mm, non-ferrous metal wires or bars, you should choose YG6; for 20-50mm, you should choose YG8, and for larger ones, choose YG11 or YG15.
2.Seriously. Check the drawing machine. Before drawing, check whether the drawing machine is stable and there must be no jumps, otherwise the drawing die is easily damaged.Clean the wire properly before drawing the wire, otherwise it is easy to reduce the service life of the mold, but also easy to form scratches on the wire, affecting the surface quality.
3. Properly clean the wire. The surface of the wire must be properly cleaned before drawing, otherwise it will not only reduce the service life of the mold, but also easily form scratches on the wire, which will affect the surface quality.
4. To choose the lubricant correctly, choose a lubricant with excellent lubrication effect, such as wire drawing powder, etc., so as to improve the service life of the mold.
5. Cool the cemented carbide drawing die well and lubricate the working area, especially when drawing at high speed, so as to maximize the life of the die.
6. A reasonable choice of compression rate should be based on the size and performance of the wire drawn. The compression rate is too small to increase production costs, and the compression rate is too large, which will cause the mold life to decrease, and even mold explosions The phenomenon occurs.
7. Pay attention to control the surface condition of the metal material. During the drawing process, if it is found that metal particles are adhered to the inner hole of the mold, and the surface of the metal material is scratched, stop immediately, remove the adhered metal particles, and polish the inner hole . Before using the mold, carefully clean the metal particles in the mold hole.
8. The most reasonable way to check the mold regularly is to do regular inspections without waiting for metal particles to appear on the mold hole walls, and to deal with abnormalities in time.
9,The care of cemented carbide drawing dieTemporarily without mould should be coated with anti-rust oil for their own protection.
