From the perspective of the entire stamping process of stamping parts, the process can actually be divided into two different processes. One of the processes is called the separation process, which mainly refers to that after the stamping material is subjected to external forces, the stress of the deformed part exceeds its own strength limit, so it breaks and separates. The other process is the plastic deformation process.
In fact, this process mainly refers to that after receiving a certain external force, the stress of the deformed part of the stamping material exceeds its yield limit, but it has not reached the strength limit, so only plastic deformation occurs, so that a certain shape and size. In the process of forming stamping parts, there are five main deformations. Do you know what kinds of variants are there?
The first deformation is three-dimensional pressing, which mainly refers to the redistribution of the volume of the stamping. In this process, there is also a partial transfer of the material to change its shape or height or thickness.
The second type is bending deformation, which mainly refers to turning the original straight sheet into a curved piece, etc .;
The third type of deformation belongs to calendering, which mainly refers to the stamping of flat blanks into parts of the required shape
The fourth kind of deformation actually refers to the forming of stamping parts, mainly after the external force is applied, the shape of the raw material is changed. The fifth type is cutting and punching deformation. The processing methods that belong to this kind of deformation include: punching, trimming and notching.
This article mainly introduces the various deformations of stamping parts. I hope that through the introduction of these contents, we can help you have a better understanding of the processing of metal stamping parts.
