Design Principles Of Metal Stamping Parts

(1) The designed stamping parts must meet the product application and technical performance, and be easy to assemble and repair.
(2) The designed stamping parts must be conducive to improving the application rate of metal materials, reducing the types and specifications of materials, and reducing the consumption of materials as much as possible. Use low-cost materials where possible to make parts blanking with no waste and less waste as much as possible.
(3) The designed stamping parts must be simple in shape and reasonable in structure, so as to simplify the mold structure and the number of processes, that is, use the least and simplest stamping process to complete the processing of the entire part, reduce the need for other methods to process, and facilitate the stamping operation. , to facilitate the organization of mechanized and automated production, in order to improve the labor consumption rate.
⑷ For the designed stamping parts, under the condition of ensuring normal use, try to make the dimensional accuracy grade and surface roughness grade requirements lower, which is conducive to the exchange of products, reduces waste, and ensures stable product quality.
⑸ The designed stamping parts should be conducive to the use of existing equipment, process equipment and process flow as much as possible to process them, and to prolong the service life of the stamping die.
Stamping parts are sometimes also used as sheet metal. The word comes from the English plate metal. Generally, some metal sheets are punched by hand or die to produce plastic deformation to form the desired shape and size, and can be further welded or a small amount of mechanical processing. More complex parts, such as chimneys commonly used in homes, tin stoves, and car shells are all Sheet Metal Parts.
The processing of stamping parts is called Sheet Metal Processing. For example, the use of sheet metal to manufacture chimneys, iron drums, fuel tanks, ventilation pipes, elbows and heads, sky garden centers, funnel shapes, etc. The main processes are shearing, bending, bending, forming, welding, riveting, etc. Certain geometry.
Stamping parts are thin-plate hardware, that is, parts that can be processed by the wrist such as stamping, bending, stretching, etc. A rough definition is-
Parts with constant thickness during machining. Correspondingly, castings, forgings, machined parts, etc., for example, the outer iron shell of the car is a sheet metal part, and some stainless steel kitchen utensils are also sheet metal parts.
Modern Sheet Metal Processes include: filament power winding, laser cutting, heavy duty machining, metal bonding, metal drawing, plasma cutting, fine welding, roll forming, sheet metal bending, die forging, water jet cutting, fine welding, etc. .
