Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention is further described
[0022] Such as Figure 1 to Figure 2 As shown, a composite gasket stamping material structure includes a metal sheet 1 and a soft metal 4, the metal sheet 1 is provided on both sides of the soft metal 4, and the side of the metal sheet 1 in contact with the soft metal 4 is provided with a The rough surface 3 is provided with a convex-concave surface 2 on the other side.
[0023] Further, the material of the metal sheet 1 is ductile steel, and when the metal sheet 1 is squeezed, it will be deformed and the contact surface will become larger.
[0024] Further, the convex side of the convex-concave surface 2 is provided with a cutting edge, the hardness range of the cutting edge is 20-30HRC, and the slope range of the cutting edge is 10°-90°.
[0025] Further, the surface hardness of the metal sheet 1 is 5-20HRC harder than that of the soft metal 4, so as to ensure the toughness ...

Abstract
The invention discloses a composite gasket punching material structure. The composite gasket punching material structure comprises metal sheets and soft metal, wherein the metal sheets are arranged atthe two sides of the soft metal; a rough surface is arranged at one side, contacting with the soft metal, of each metal sheet; and a convex and concave surface is arranged at the other side of the metal sheet. The composite gasket punching material structure is relatively simple, can be used in acid/alkali environments and is unlikely to be corroded. The gasket structure has very good toughness,does loosen or reverse after vibrating strongly, and can effectively achieve the effects of loosening prevention and tightening. The convex and concave surfaces on the gasket structure greatly improvethe frictional resistance. Fiber webs on the surface of the gasket structure can effectively prevent an anti-acid film and/or anti-alkali film from being damaged.
Description
technical field [0001] The invention relates to a material structure, in particular to a composite pad stamping material structure. Background technique [0002] Gaskets play an important role in various components. When we need to fasten two connecting parts, we often put a gasket under the nut so that the gasket can rely on friction when the nut is tightened. To achieve the effect of anti-loosening. However, such gaskets are inelastic, and after they are fastened with the screws or nuts, the screws or nuts will be backed up after violent vibrations, so that they may become loose or even fall off. Therefore, the existing gasket also has potential safety hazards. As the precision of electronic components is constantly improving, people's requirements for gaskets are also gradually increasing. The current gaskets have poor rigidity and cannot withstand high temperatures, and traditional gaskets are single-layered, without good elasticity, easy to deform, and cannot achieve...
