Application of Carbide Alloy in Deep Drawing Mould
Deep drawing is an important industrial process for producing complex parts with high accuracy and surface quality, such as cans, cups, boxes and shells. It is usually formed by a single-stage or multiple-stage progressive pressing process. The development of deep drawing technology is closely related to the corresponding die and die material. Carbide alloy is one of the most important materials in deep drawing dies.
Carbide alloy has many advantages, such as high hardness, wear resistance, heat resistance and oxidation resistance. The hardness of carbide alloy is much higher than that of most punching materials, and its wear resistance is far superior to that of ordinary tool steel. Its heat resistance operation temperature can reach up to 1000℃, and its oxidation resistance temperature can reach up to 1200℃. Its strength and hardness remain unchanged even at high temperatures, which is suitable for high speed and continuous processing. In addition, carbide alloy is also easy to be machined and welded, and its working grain size can reach up to submicron level. Due to the unique advantages of carbide alloy, it has become one of the most widely used materials in deep drawing shells and other parts with complex shape.
The use of carbide alloy in deep drawing die is mainly related to the materials of the mould core, which are usually made of powder metallurgy hard alloy or binder bonded cemented carbide. The advantage of powder metallurgy hard alloy is that it can obtain a fine grain size with sufficient hardness and strength after sintering and heat treatment, which is suitable for precise forming with high surface finish requirement. For binder cemented carbide, it has very good abrasion resistance and the structure is very stable even at high temperatures, which is suitable for deep drawing of cold plastics.
Carbide alloy has good performance in deep drawing die and is of great benefit to deep drawing industry. The combination of carbide alloy material and die forming technology fully make use of its superior performance, greatly improve the efficiency and quality of deep drawing workpiece. For example, in deep drawing of thin-walled workpieces, the combination of carbide alloy materials and low stress adjustment technology can effectively reduce the die stress, improve the running performance of the die, and reduce the maintenance workload of die. At the same time, the use of carbide alloy materials in deep drawing can also increase the long-term service life of the die, reduce the production cost, and improve the overall performance of the deep drawing process.
In conclusion, the use of carbide alloy material in deep drawing die can make full use of its high strength and hardness, wear resistance, heat resistance and oxidation resistance performance, greatly improve the efficiency and quality of deep drawing workpiece, and has a very broad application prospect.
