What are the design methods of stamping blanks

Design has always had a very important effect in production work, and we must understand this very briefly. The same is true for stamping parts. In practical work, the design of blanks for stamping parts can be completed in different ways. There are four commonly used methods. Let's explain each of the different methods in detail and hope to help. The first method on the list is called the slip line method. However, if you choose this method, you need to be satisfied with certain prerequisites. The basic assumption about the slip line method is this: the thickness of the sheet flange remains unchanged, and the plane strain is maintained, the data is isotropic, there is no hardening, and the impact of the conflicting force is also neglected. However, since the slip line method of stamping parts is appropriately messy in accounting, it is difficult to implement. The second method is called the ji Xu mapping method, and this method is also proposed under assumptions. When we neglected the conditions of deformation force, stress-strain relationship and gap conflict, we combined some assumptions to complete the mapping of workpiece to blank. In the study, we found that the geometric mapping method of stamping parts will be affected by the discrete accuracy. The confirmation of reasonable discrete accuracy will also have a certain impact on the accounting speed and opening accuracy of the accounting machine. The third is the experience method. This method is well understood. In short, we have found certain experience from the past processing cases. This method is mainly used for expandable stamping parts with relatively simple shapes, such as rotating parts, zigzag parts, etc. Generally speaking, this method will have a certain error in accuracy, because it needs to consider many factors. One is called the imitation method. Relatively speaking, this method is still used more often. When applying this method, it is also necessary to assume certain conditions. Together with the similarity of mathematical descriptions of some physical problems, through mathematical similar theories, a model is constructed to imitate the metal activities of the sheet flange, and then the stamping parts are processed .
