Stamping processing is a production technology that uses the power of conventional or special stamping equipment to make the sheet directly subject to deformation force in the mold and deform, so as to obtain a certain shape, size and performance of the product parts. Sheets, dies and equipment are the three elements of stamping processing. Stamping is a cold deformation method for metals.

Therefore, it is called cold stamping or sheet metal stamping, referred to as stamping. It is one of the main methods of plastic processing (or pressure processing) of metals, and is also subordinate to material forming engineering technology.

The stamping processing processes are: punching, cutting, trimming, tongue cutting, cutting, flaring, punching, punching, punching, punching, punching center hole, fine blanking, progressive die, single-process die, combined punching die, embossing, embossing, forming.

Blanking. Blanking is a stamping process that uses a die to separate part of the material or process from another part of the material, work (sequence) or waste. Blanking is a general term for separation processes such as cutting, blanking, punching, punching, punching, slotting, cutting, chiseling, trimming, tongue cutting, cutting, and refurbishment.

Punch the center hole. Punching the center hole is a kind of stamping process that forms a shallow concave center hole on the surface of the process piece, and the back material does not have a corresponding protrusion.

Figuration. Forming is a general term for the stamping process that changes the shape and size of the process according to the flow of the material but not according to the separation of the material. Embossing This paragraph Embossing is a stamping process that forcibly extrudes the material locally and forms a shallow concave pattern, pattern, text or symbol on the surface of the process piece.

The back of the embossed surface does not correspond to a concave protrusion.

Embossing. Convex pressing is a kind of punching circular pressing process that is extruded into one side of the process piece with a convex die and forced to flow into the opposite pit to form a bulge.

Combination dies. The combined die is a general, adjustable complete set of punches that gradually form various punches according to the geometric elements (straight line, angle, arc, hole) one by one. The outline of the planar punch generally needs to be punched into several sets of cavity and Huihe punching dies in stages.

Single-process mold. A single-process die is a die in which only one process is completed in a single stroke of the press.

Fine blanking. Fine blanking is a kind of smooth blanking, which uses a fine blanking die with a toothed pressing plate to make the entire section of the punch completely or basically clean.

Punching grooves. Punching is a stamping process in which scrap is separated from a material or process piece along an open profile that is grooved in depth longer than the width.

Rush. Blanking is a stamping process in which scrap material is separated from a material or process piece along an open profile that forms a notch whose depth does not exceed its width.

Punching. Punching is a stamping process that separates the scrap material from the material or process piece along the closed contour, and obtains the required hole in the material or process piece.

Flaring. Flaring is a stamping process that expands the open part of a hollow or tubular part outward. Cutting off This section Cutting off is a stamping process that separates the material along the open profile, and the separated material becomes a workpiece or process piece.

Tongue cutting. Tongue cutting is a stamping process in which materials are partially rather than completely separated along an open profile. The partially separated material, which has a certain position required by the workpiece, is no longer on the plane on which it was before separation.

Trimming. Trimming is a stamping process that uses die trimming to form the edge of the process piece, so that it has a certain diameter, a certain height or a certain shape.

Cut. Cutting is a stamping process in which materials are partially rather than completely separated along an open profile. The material that is cut and separated is located or substantially on the plane in which it was before separation.

DefinitionStamping is a production technology that uses a die mounted on a press to apply a deformation force to the sheet metal placed in the mold, so that the sheet metal is deformed in the mold, so as to obtain a certain shape, size, and performance. Because the stamping process is often carried out at room temperature, it is also called cold stamping. Stamping forming is one of the metal pressure processing methods, it is based on the theory of metal plastic deformation of the material forming engineering technology, stamping processing raw materials are generally sheet metal or strip material, so it is also called sheet metal stamping.

Stamping process refers to the specific method of stamping processing (the sum of various stamping processes) and technical experience; A stamping die is a special special tool for processing sheet metal into stamped parts.

Sheets, dies and stamping equipment are the three essential elements that make up a stamping process.

Characteristics of stamping and its application.

Stamping production relies on dies and presses to complete the processing process, compared with other processing methods, in terms of technology and economy has the following characteristics: (1) the dimensional accuracy of stamping parts is guaranteed by the die, with exactly the same characteristics, so the quality is stable, interchangeability is good.

2) Due to the use of mold processing, it can obtain parts that cannot be or are difficult to manufacture by other processing methods, with thin walls, light weight, good rigidity, high surface quality and complex shapes.

3) Stamping generally does not need to heat the blank, nor does it cut a large amount of metal like cutting processing, so it not only saves energy, but also saves metal.

4) For ordinary presses, dozens of pieces can be produced per minute, while high-speed presses can produce hundreds or thousands of pieces per minute. So it is a high-efficiency processing method.

Due to the above-mentioned outstanding characteristics, the stamping process is widely used in various fields of the national economy. For example, aerospace, machinery, electronic information, transportation, weapons, daily electrical appliances and light industry and other industries have stamping processing. Not only is it widely used in the industry, but everyone is directly involved in stamping products on a daily basis.

Stamping can be used to manufacture small precision parts in watches and instruments, as well as large panels for automobiles and tractors. Stamping materials can be made of ferrous metals, non-ferrous metals, and some non-metallic materials.

Shortcomings: Stamping also has some disadvantages, which are mainly manifested in noise and vibration during stamping processing. These problems are not entirely caused by the stamping process and the die itself, but mainly due to the backwardness of traditional stamping equipment. With the progress of science and technology, these two kinds of public hazards will definitely be solved.

Sheet metal stamping is a common machining process that is mainly used to produce metal parts of various shapes. The sheet metal stamping process includes the following:

1.Shearing: A shears are used to cut the sheet metal into the desired shape.

2.Punching: A punching machine is used to punch out the holes in a patterned arrangement on the sheet metal to facilitate the assembly and fixing of the parts.

3.Bending: Use a bending machine to bend the sheet metal slowly and widely along a certain bending line into the desired shape.

4.Deep drawing: A deep drawing machine is used to draw the sheet metal into the desired shape.

5.Die Casting: A sheet metal is placed into a die casting mold and extruded into the desired shape by high pressure.

6.Welding: Metal parts of different shapes are joined together through a welding process to form a complete product.

7.Surface treatment: surface treatment of sheet metal products, such as spraying, plating, etc., to protect the surface of the product and improve the aesthetics of the product.

These processes usually require the use of professional sheet metal stamping equipment and tools to ensure machining accuracy and production efficiency.
