With the vigorous development of finite element simulation research in stamping parts processing, more and more people are beginning to use finite element methods to understand the complex problems of stamping parts forming, and continue to achieve success. The formability of stamping parts is directly related to the quality of the parts. There may be various reasons for the tear deviation of stamping parts during processing. Let‘s find out together.

Reasons for tearing deviation in stamping parts processing:

1. During the processing of stamped parts, the parameters of the process may be unreasonable, so it is generally required that the core pressure and the two parts are joined together, and the sheet material is plastically deformed to form when the machine slider slides down. However, due to defects, such as the quality of unstable parts of the print, it indicates that the pressure of the machine tool in the pressure imbalance state during the production process forms the design of the extrusion part of the substrate flange processing, which indicates the characteristics of the small pressing surface in the initial design of the die.

2. However, the formation of the seat ring of the pressing core is ignored, which is related to the error between the machining part of the die and the design of the drawings. Before forming the extrusion part, it is carried out through the positioning pin and the hole on the top surface of the core material pressure, so that the core material pressure should ensure stability, be reliable and correct. In the construction of this work, the ground guide is very slippery, otherwise the workpiece will be unstable during the forming process, causing the pressure of the core to collide with the die wall.

3. If other factors are taken into account in the die structure, and the use of special guidance for sliding is ignored, the structure of the processing-oriented profile is adopted, and the space behind is too large to be adjusted, which will cause the stamping parts to be torn. Stainless steel is widely used in industrial production due to its excellent performance, but its performance in stamping parts processing is poor, the surface of the sheet is easy to scratch and the die is easy to adhere to tumors, which has a great impact on the processing quality and production efficiency of stamping parts.
