Description

Technical Field

[0001] The invention relates to the technical field of stainless steel thin plate processing, in particular to a local stamping device for a stainless steel thin plate. Background Art

[0002] Stainless steel sheet refers to a thin stainless steel sheet, usually with a thickness ranging from 0.2 to 4 mm. This sheet material plays an important role in many fields such as industrial production, architectural decoration, and household goods.

[0003] Stainless steel sheets contain alloy elements such as chromium (Cr) and nickel (Ni). Chromium can form a dense chromium oxide protective film on the surface of the sheet, which can effectively prevent corrosive media such as oxygen and moisture from contacting the base metal, thereby preventing rust and corrosion. For example, in the marine environment, 316L stainless steel sheets (containing molybdenum to enhance corrosion resistance) can resist the erosion of seawater and can be used to manufacture some auxiliary facilities of offshore platforms, shells of marine equipment, etc.

[0004] In many industrial and daily applications, it is necessary to increase the structural strength of stainless steel sheets through local stamping. For example, in the field of automobile manufacturing, stainless steel sheets used in certain parts of the car body will be locally stamped to form reinforcement ribs. These reinforcement ribs can effectively resist various external forces such as vibration, collision and twisting force on the car body during driving, and improve the overall rigidity and safety of the car body.

[0005] In the manufacture of some mechanical parts, such as brackets or housings made of stainless steel sheets, locally stamped concave-convex structures can enhance their load-bearing capacity, enabling them to better support internal components or withstand external working loads. The existing technology generally requires workers to manually load and position the stainless steel sheets, which is inconvenient and inefficient.
