The sealing gasket occupies a very important position in modern industrial enterprises, and the quality of sealing is directly related to the continuity of production, the safety of property, energy conservation, environmental protection and physical and mental health of people, so the development of the gasket is more and more valued by people. With the rise of modern industries, particularly modern petroleum, chemical industry, nuclear industry and large-scale power stations, pressure vessels develop towards high temperature, high pressure, high vacuum, deep cooling, large-scale and multi-series directions, and continuously provide new requirements for gasket sealing. The principle of the sealing gasket is that the sealing gasket is compressed by external force to cause the sealing gasket to generate elastic or plastic deformation so as to fill up the microscopic unevenness on the sealing surface, and the sealing gasket is made of metal or nonmetal plate-shaped materials through processes of cutting, stamping or cutting and the like and is used for sealing connection between pipelines and sealing connection between machine parts of machine equipment.
The stamping is a forming processing method for obtaining a workpiece (stamping part) with a required shape and size by applying external force to a plate, a strip, a pipe, a section bar and the like by a press machine and a die to cause plastic deformation or separation. The metal gasket is generally manufactured by a punching machine, and because the metal gasket is low in cost and high in manufacturing efficiency, a metal sheet can be fed into the punching machine and pressed under the action of a die, and therefore the metal gasket cannot be punched in the processing process.
