Different types of metal stamping processes have their own unique characteristics and applicable scenarios. The following is a detailed analysis of stamping processes such as perforation, punching, stretching, and forging:
1. Perforation processFeatures:Hole holes are punched in metal materials through presses and dies.High precision, a large number of holes can be made in a short time.The shape and size of the holes can be controlled by changing the die, which has high flexibility.There are certain requirements for the thickness of the material. Too thick or too hard materials may cause damage to the die.Applicable scenarios:Applicable to scenarios where a large number of holes need to be made in metal sheets, such as the production of radiators, filters and other products.In the fields of automobiles, aerospace, etc., it is used to manufacture various parts with holes.2. Punching processFeatures:Use a press to punch metal sheets into the required shape.High efficiency, suitable for mass production, and can punch out multiple parts at the same time.High requirements for material quality, and the hardness, toughness and other characteristics of the material will affect the punching effect.Applicable scenarios:Widely used in the manufacturing process of automobiles, home appliances, electronic equipment and other products, especially in production scenarios that require a large number of parts of the same shape.Applicable to the manufacture of parts with relatively simple shapes and high dimensional accuracy requirements.3. Stretching processFeatures:The flat metal sheet is stretched into a hollow shape with a certain depth through a press and a die.It can improve the utilization rate of materials and reduce the generation of waste.The shape and size of the product are stable, but wrinkles and cracks are prone to occur during the stretching process, and precise control of pressure and speed is required.Applicable scenarios:Applicable to the manufacture of various hollow parts with complex shapes, such as automobile fuel tanks, oil pans, etc.It is also widely used in aerospace, electronics and other fields, such as the manufacture of various containers and shells.4. Forging processFeatures:Use impact force or pressure to change the shape and properties of metal.It can improve the microstructure of the metal and improve its mechanical properties.It can manufacture parts with complex shapes and high dimensional accuracy.A lot of heat will be generated during the forging process, and special equipment is required for cooling and processing.Applicable scenarios:Widely used in the field of industrial manufacturing, especially in the manufacturing of high-strength, high-performance and high-precision parts, such as parts in automobile engines, mechanical equipment, aerospace and other fields.Applicable to the manufacture of parts with high material performance requirements, such as gears, shafts, etc.In summary, different types of metal stamping processes have their own unique characteristics and applicable scenarios. When choosing a stamping process, it is necessary to comprehensively consider factors such as the specific requirements of the product, production batch, and material properties.
