Metal stamping parts is metal processing, machinery manufacturing the most commonly used parts. Stamping parts processing is the use of mold separation or forming of the metal plate processing methods. Its application is very broad. Metal stamping parts are mainly made of hot rolled or cold rolled (mainly cold rolled) sheet metal materials such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper Alloy plate, aluminum and aluminum alloy plate. Today introduced metal stamping slip line method:
The basic assumption of the slip line method is that the thickness of the flange of the sheet is constant and in a plane strain state, the material is isotropic and has no hardening, irrespective of the influence of the friction distribution on the plastic flow. By the three common basic methods.
Geometric mapping method:
The method was first proposed by R. Sowerby et al. They considered that the mapping of the workpiece to the blank could be realized according to some assumptions without considering the boundary conditions such as deformation force, stress-strain relationship and boundary friction.
Experience method:
The method is mainly based on some empirical formulas, so its application range is affected. It is mainly applied to developable stamping parts with simple shapes (such as rotating parts, bending parts, or stamping parts composed of these simple parts). In general, the method of freeform surface plate parts developed by experience are all improvise methods, the accuracy of which is affected by the richness of user experience, the empirical formula adopted and the choice of specific process parameters, Its accuracy needs to be further improved.
Simulation method:
Under certain assumptions, the simulation method simulates the metal flow in sheet flanges based on the similarity of mathematical description of many physical problems through the mathematical similarity theory and the model of other physical media. Laplace and Poission equations are widely used in sheet metal forming.
Stamping parts processing, including blanking, bending, drawing, forming, finishing and other processes. The materials for stamping are mainly hot rolled or cold rolled (mainly cold rolled), such as carbon steel, alloy steel, spring steel, galvanized steel, tinplate, stainless steel, copper and copper alloy Board, aluminum and aluminum alloy plate. Metal stamping parts hardness testing using Rockwell hardness tester. Small, complex-shaped stampings that can be used to test small flat surfaces can not be detected on a common benchtop Rockwell hardness tester.
