In the world of modern manufacturing, the selection of the right materials is crucial for achieving high-quality and efficient production. One such material that plays a vital role is cold work tool steel. Here UTSTEEL discovers the diverse applications of this essential material in the realm of stamping dies.
What is the Cold Work Tool Steel?
Cold work tool steel refers to tool steel used for shearing, punching, stamping, bending, cold extrusion and other processing of metal or non-metallic materials in a cold state. Its main components include carbon, chromium, molybdenum, vanadium, tungsten and other elements. The addition of these alloying elements makes cold work tool steel have high hardness, high wear resistance and good toughness, and can withstand large impact loads and complex stress states.
Common Applications of Cold Work Tool Steel in Stamping Dies
Punching Dies
Punching dies are used to punch metal sheets into parts of specific shapes, requiring the dies to have extremely high hardness and wear resistance to withstand repeated impact and friction. Cold work tool steels such as D2 and Cr12MoV are often used to make punching dies because of their high hardness and wear resistance.D2 steel has excellent wear resistance and hardenability, and can maintain a sharp edge under high stress conditions. Its high hardness makes the mold less likely to deform and wear during use, thereby improving the punching accuracy and mold life. Cr12MoV steel adds molybdenum and vanadium elements to Cr12, which makes it have higher wear resistance and toughness, and is suitable for making high-load, high-strength punching dies.
Bending Mold
Bending molds are used to bend metal sheets into the desired shape, requiring the mold to maintain a stable size and shape under high pressure. Cold work tool steel such as SKD11 is widely used in the manufacture of bending molds due to its good hardenability and dimensional stability. SKD11 steel is a high-carbon, high-chromium cold work tool steel that has excellent hardness and toughness after quenching and tempering. Its high hardenability ensures that the mold has a uniform hardness distribution across the entire cross section, thereby improving the service life and performance stability of the mold. During use, the bending mold needs to withstand high pressure and repeated bending forces. The dimensional stability of SKD11 steel ensures that the mold can still maintain stable performance under high stress conditions and ensure bending accuracy.
Drawing Die
Drawing dies are used to stretch metal sheets into deep cavity shapes, requiring the dies to have good hardness and toughness to withstand large deformation forces. Cold work tool steels such as D2 and SKD11 perform well in drawing dies due to their excellent hardness and toughness. D2 steel has high hardness and high wear resistance, which can maintain a sharp cutting edge during the drawing process and avoid premature wear of the die. Its good toughness ensures that the die will not crack when subjected to large deformation forces, thereby increasing the service life of the drawing die. SKD11 steel is widely used in the manufacture of various high-strength and high-precision drawing dies due to its good comprehensive properties.
Shearing Die
Shearing dies are used to shear metal sheets, requiring the die to have high hardness and wear resistance to maintain a sharp edge during the shearing process. Cold work tool steel, such as Cr12MoV, is often used in the manufacture of shearing dies for its high hardness and wear resistance. The high hardness of Cr12MoV steel ensures that the shearing die can maintain a sharp edge for a long time during use, reducing the wear and replacement frequency of the die.
