Stamping process characteristics of precision metal stamping molds

Stamping parts are thin plate hardware, that is, parts that can be processed by stamping, bending, stretching, etc. A general definition is - parts whose thickness does not change during processing. The corresponding ones are castings, forgings, machined parts, etc. For example, the iron shell on the outside of a car is a sheet metal part, and some cabinets made of stainless steel are also sheet metal parts.

So far, there has not been a relatively complete definition of stamping parts. According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold processing process for metal sheets (usually below 6mm), including shearing, punching /cutting/compositing, folding, welding, riveting, splicing, forming (such as automobile body), etc. Its distinctive feature is that the thickness of the same part is consistent. Explanation from the 5th edition of Modern Chinese Dictionary: Verb, to process metal plates such as steel plates, aluminum plates, copper plates, etc.

To put it bluntly, stamping parts are a kind of car repair technology, which means to repair the deformed parts of the metal shell of the car. For example, if the car body shell is hit with a crater, it can be restored to its original shape through sheet metal.

Generally speaking, the basic equipment of a stamping parts factory includes shears, CNC punches/lasers, plasma, water jet cutting machines/composite machines, bending machines and various auxiliary equipment such as: decoilers, leveling machines, deburring machines, point Welding machine etc.

Usually, the three most important steps in a metal stamping mold factory are shearing, punching/cutting, and folding.

Stamping parts are sometimes also called wrench. This word comes from the English platemetal. Generally, some metal sheets are stamped by hand or mold to cause plastic deformation to form the desired shape and size, and can be further processed by welding or a small amount of machinery. Forming more complex parts, such as chimneys commonly used in homes, tin stoves, and car casings are all sheet metal parts.

Stamping parts processing is called sheet metal processing. Specifically, for example, plates are used to make chimneys, iron barrels, fuel tanks, ventilation ducts, elbows, large and small heads, garden spaces, funnel shapes, etc. The main processes are shearing, bending and buckling, bending, welding, riveting, etc., which require Certain knowledge of geometry.

Stamping parts are thin plate hardware, that is, parts that can be processed by stamping, bending, stretching, etc. A general definition is parts whose thickness does not change during the processing process. The corresponding ones are castings, forgings, machined parts, etc. For example, the iron shell on the outside of a car is a sheet metal part, and some cabinets made of stainless steel are also sheet metal parts.

Modern sheet metal processes include: filament power winding, laser cutting, heavy machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting, precision welding, etc.
