Appearance treatment and stamping process of metal parts stamping die

Appearance treatment and stamping process of stamping die in stamping parts forming

Stamping parts processing molding must be used to stamping molds, and most of the stamping die before the use of the appearance of processing, and then improve the quality of stamping parts. But in terms of the appearance of stamping die processing methods, but also not only the processing efficiency is fast, and the processing quality is good, in addition to the internal sharp angle of the cavity and very narrow and deep cavity, other aspects can be competent.

If the material is softer, then the punching gap needs to be modified, the specific method is to repair the arc or slope at the end of the convex die edge, the use of blowing equipment such as vacuum cleaner, in the pad drop hole to add blowing gas. Stamping die blade wear and stamping out of the parts have hair edge situation, so the demand to repair the blade.

Stamping is at room temperature, the use of stamping die installed on the press to put pressure on the data, so that it occurs separation or plastic deformation, and then obtain the required parts of a pressure processing method. The data of stamping die are steel, cemented carbide, steel knot cemented carbide, zinc base alloy, low melting point alloy, aluminum bronze, polymer data and so on.

Stamping parts processing production efficiency and convenient operation, easy to achieve mechanization and automation, this is because stamping is dependent on die and stamping equipment to end processing, ordinary press travel times can be up to dozens of times per minute, high-speed pressure to reach hundreds of times per minute or more, and each stamping trip may get a punch.

Not only that, stamping can be processed out of larger size, messy shape of the parts, such as small to the clock stopwatch, large to the car longitudinal beam, cover-up parts, coupled with the stamping data of the cold deformation hardening effect, stamping strength and stiffness are high.

In the steel of the world, there are 50~60% made of plates, most of which are finished with punching and squeezing. automobile body, radiator sheet, steam pot drum, container shell, motor, electrical core silicon steel sheet, etc., where stamping processing. instrumentation, household appliances, office inflexible,Metal parts, storage utensils and other products, there are also a large number of stamping parts. Stamping is an efficient pro-pigment initiative, the use of composite mold, abnormal is multi-position progressive mold, can be completed in a press multi-channel stamping technology operation, complete the automatic generation of materials. The generation speed is fast, the rest time is long, the pro pigment cost is low, the collective can pigment hundreds of pieces per minute, is loved by many processing plants.

Stamping parts and castings, forgings fighting strength, there are thin, uniform, light, strong characteristics. Stamping can produce workpieces with reinforcement, ribs, coiled or flip edges that are difficult to manufacture at this skilled diameter to improve their rigidity. As a result of the rejection of rough mold, the accuracy of the workpiece can reach the micron level, and high precision, consistent specifications, can be punched out of the hole nest, convex table and so on. In the actual production, commonly used with the stamping process approximation of the process test, such as drawing performance test, bulging performance test and other inspection materials stamping performance, in order to ensure the quality of the finished product and high pass rate.
