Process Characteristics of Sheet Metal Stamping

Sheet metal stamping is a general term for the processing technology of punching, bending, stretching, pressing and other processing of metal sheets using stamping machines and dies. It has the characteristics of high efficiency, high precision, stable quality, good interchangeability, strong adaptability, high flexibility, material saving and energy saving, as well as technology intensiveness and high automation level. These characteristics make sheet metal stamping widely used in various fields of the national economy, such as automobiles, electronics, communications, machinery manufacturing and other fields.

1. High efficiency and high precision

High production efficiency: sheet metal stamping is completed by dies and stamping equipment. The number of strokes of ordinary presses can reach dozens of times per minute, and high-speed presses can even reach hundreds of times or more, realizing efficient and fast mass production.

High precision: Due to the use of precision dies, the size and shape accuracy of stamping parts can reach micron level, and the repetition accuracy is high and the specifications are consistent, which can meet the processing requirements of high-precision parts.

2. Stable quality and good interchangeability

Stable quality: During the stamping process, the die ensures the size and shape accuracy of the stamping parts, and generally does not damage the surface quality of the stamping parts. At the same time, the long life of the die makes the quality of the stamping parts stable and reliable.

Good interchangeability: Due to the high precision and consistency of stamping parts, stamping parts of the same batch or different batches have good interchangeability, which is convenient for subsequent assembly and use.

3. Strong adaptability and high flexibility

Strong adaptability: sheet metal stamping can be used to process a variety of metal materials, such as steel plates, aluminum plates, copper plates, etc., and can produce parts with complex shapes and a large range of sizes.

High flexibility: sheet metal stamping can design and manufacture molds according to actual needs to meet the processing needs of parts with different shapes, sizes and performance requirements.

4. Material saving and energy saving

Material saving: Stamping processing generally does not generate chips and debris, the material utilization rate is high, and material consumption can be further reduced through optimized design.

Energy saving: Stamping processing does not require other heating equipment, and has high production efficiency, making energy consumption relatively low.

5. Technology intensive and high level of automation

Technology intensive: The molds used in stamping processing are generally specialized, and the mold manufacturing has high precision and high technical requirements, which is a technology-intensive product.

High level of automation: With the advancement of mechatronics technology, stamping processing has gradually realized automated production, including a fully automatic production process from unwinding, leveling, punching to forming and finishing.
