Description

Technical Field

[0001] The utility model relates to the technical field of metal gaskets, in particular to a wear-resistant and anti-skid metal gasket. Background Art

[0002] Metal gaskets are made of high-precision, high-hardness sheet materials. They are usually used in the adjustment and measurement of precision molds or precision hardware, or as pads. They are called precision gaskets, sometimes also called mold gaskets or precision gap sheets. When metal gaskets are used, they will slide relative to each other after being installed on the connecting parts, causing relative friction between the connecting parts and the metal gaskets. Long-term friction causes damage to the metal gaskets and shortens their service life. Damage to metal gaskets can cause the connecting parts to loosen, affecting the use of the connecting parts. Metal gaskets are generally ring-shaped or other closed structures. When replacing them, the connecting parts need to be disassembled, which is very time-consuming and labor-intensive.
