A Comprehensive Analysis Of Stamping Processes And Procedures

Stamping Process Characteristics and Procedures Introduction Stamping is essential for the production of automobile bodies, chassis, fuel tanks, radiator fins, container shells, and the silicon steel cores of motors and electrical appliances. Instruments, household appliances, bicycles, office machinery, and household utensils also contain a large number of Silver Electrical Riveted Components.

Stamping procedures can be divided into four basic steps:

Blanking: The stamping process that separates sheet metal (including punching, blanking, trimming, and slitting).

Bending: The stamping process that bends sheet metal along a bending line into a specific angle and shape.

Drawing: The stamping process that transforms flat sheet metal into various open hollow Stamping Parts, or further modifies the shape and size of hollow parts.

Fine Blanking: The process of producing Silver Electrical Riveted Components with high precision, especially for products with high requirements for dimensions and surface finish, using fine blanking dies to achieve the drawing requirements.

Partial forming: Stamping processes that use various local deformations to change the shape of blanks or stamped parts (including flanging, bulging, leveling, and shaping processes).

Stamping is a high-efficiency, low-material-consumption processing method. It is suitable for large-volume production of Silver In-Die Riveting Connections, facilitating mechanization and automation, and boasts high production efficiency. Furthermore, stamping production strives for minimal or zero waste, and even in cases where scrap material exists, it can be fully utilized.

The operation is convenient and does not require highly skilled operators.

Silver Contact Riveted with Copper Terminal generally do not require further machining and have high dimensional accuracy.

Copper Contact Terminals have good interchangeability. Stamping processing has good stability; stamped parts from the same batch can be interchanged without affecting assembly or product performance.

Because Silver Contact and Stampings use sheet metal, their surface quality is good, facilitating subsequent surface treatment processes (such as electroplating and painting).

Stamping can produce parts with high strength, high rigidity, and light weight.

Riveted Components produced in batches using molds are inexpensive.

Stamping can manufacture complex-shaped parts that are difficult to produce using other metal processing methods.

(I) Separation Process
Sheet metal is separated along a certain contour line under external force to obtain finished and semi-finished products with specific shapes, dimensions, and cut surface quality.

Separation Condition: The internal stress of the deformed material exceeds the ultimate tensile strength σb.

Blanking: Blanking is done by punching along a closed curve using a die; the punched-out portion is the part. Used for manufacturing various shapes of Riveted Assemblies.

Punching: A die is used to cut along a closed curve; the punched-out portion is scrap. There are several forms, including front punching, side punching, and overhead punching.

Trimming: The edges of the formed Silver Electrical Riveted Components are trimmed neatly or cut into a specific shape.

Separation: Separation is achieved by punching along an open curve. Separation is frequently used when the left and right parts are formed together.

(II) Forming Process

The blank undergoes plastic deformation without cracking to obtain finished and semi-finished products of a certain shape and size.

Forming Condition: Yield strength σS < Internal stress of the material < Ultimate tensile strength σb.

Drawing: Forming sheet blanks into various open hollow parts.

Flanging: The edges of sheet metal or semi-finished products are formed along a certain curve with a certain curvature to create vertical edges.

Forming: A forming method used to improve the dimensional accuracy of formed Silver Contact and Stamping parts or to obtain small corner radii.

Flanging: Creating vertical edges on pre-punched sheet metal or semi-finished products, or on unpunched sheet metal.

Bending: Bending sheet metal along a straight line into various shapes; this can process Copper Contact Terminals with extremely complex shapes.

In core fields such as new energy low voltages electrical appliances, and relays, the demand for high-precision stamped parts is particularly stringent. Copper Stamping with Silver Electrical Riveted Components is made using the aforementioned mature stamping process system. It is produced through multiple processes such as precise blanking, bending, and shaping, combined with high-quality molds and professional stamping equipment. It has excellent dimensional accuracy, structural strength, and conductivity, and can perfectly match the stringent assembly standards of low-voltage electrical appliances and relays, providing reliable component support for the stable operation of related equipment.
