How to make stamping parts by simulation?

  Because only the stamping parts with relatively simple shape can establish the corresponding slip line field, and only under the special simple boundary conditions can the mathematical expression of the slip line be obtained from the solution of the characteristic square. In addition, the slip line method is difficult to be used in the actual production of the stamping blank because of the complicated mathematical operation. It is widely applied in production. At the same time, the geometric mapping method is also one of the blank design methods for stamping parts. Its theoretical basis is to realize the mapping from workpiece to blank according to some assumptions without considering the boundary conditions such as deformation force, stress-strain relationship and boundary friction.

  Dalian stamping parts for different stamping products usually have different prices, many people still understand that for the same stamping products, if we have different requirements on the sheet metal, it will result in different prices of products, if the requirements on the sheet metal slightly higher, then the price will be slightly higher. . When we make stamping parts, we need to have a full understanding of the thickness of the sheet metal according to our actual use; on this basis, we make an inquiry with the stamping parts processing factory, so that we can get a reasonable price, but also meet our use requirements.

  However, the method widely used in blank forming of stamping parts is simulation method. Under certain assumptions, according to the similarity of mathematical description of many physical problems, the metal flow of sheet metal flange is simulated by mathematical similarity theory and the model composed of other physical media. This design method requires the design of electrolyte devices and data measurement, so its accuracy is affected by artificial factors.
