Metal stamping parts are the process of punching plates, strips and other materials into parts through metal molds. The following is a detailed introduction to metal stamping parts:
1. Definition and characteristics
Definition: Metal stamping parts use punch presses and molds to apply pressure to metal plates to make them plastically deform or separate, so as to obtain parts of the required shape and size.
Features:
High precision: Stamping processing can achieve high dimensional accuracy and shape accuracy.
High efficiency: Stamping production speed is fast and suitable for mass production.
Low cost: Once the mold is made, the material utilization rate in subsequent production is high and the cost is relatively low.
2. Material selection
The materials of metal stamping parts are generally low-carbon steel, high-quality carbon structural steel and stainless steel. In addition, non-ferrous metals such as aluminum and its alloys are also commonly used in stamping processing. These materials have good plasticity and processing properties, and can meet the needs of stamping parts in different fields.
3. Process type
Metal stamping processes include many types, such as perforation, punching, stretching, forging, piercing, embossing, etc. These process types are selected according to different needs and material properties to achieve specific design effects.
Perforation: Punching holes in metal sheets to form multiple small hollow areas.
Punching: Cutting small or medium-sized metal parts from large metal sheets. Punched parts are not discarded but are considered finished products.
Stretching: Fixing the two ends of the metal sheet and generating high impact force through the punch to deform it to match the cross-section of the die.
Forging: Punching small pieces of metal into specific shapes to increase their resistance to impact and other physical wear.
Punching: Creating cracks in metal sheets without generating scrap iron sheets.
Embossing: Producing unique raised surfaces on metal sheets for various decorative and functional needs.
4. Application fields
Metal stamping parts are widely used in various fields, including but not limited to:
Automotive manufacturing: Automotive stamping parts include engine parts, chassis parts, body structural parts, etc., which are an indispensable part of automobile manufacturing.
Electronic and electrical industry: such as the internal parts of household appliances such as rice cookers and microwave ovens, as well as the shells and internal structural parts of electronic products.
Financial industry: Precision metal stampings in banknote counters are used to ensure the accuracy and stability of the equipment.
Other fields: such as aerospace, medical equipment, building hardware, etc., also use a large number of metal stampings to meet specific design and functional requirements.
5. Summary
As an important metal processing method, metal stampings have the advantages of high precision, high efficiency and low cost. By selecting the right materials and process types, metal stampings that meet various needs can be produced. These stampings are widely used in many fields such as automobile manufacturing, electronics and electrical appliances, finance, etc., providing strong support for the development of modern industry.
