What are the common problems in the process of metal automobile stamping parts?
Metal stamping parts are one of the most important processes in fabrication and production. The quality of products manufactured by metal stamping parts factories will lay the foundation for the overall appearance and performance. However, in actual production, there are often some problems in the process of metal stamping parts. Let’s summarize them below.
First. Turning deformation of metal stamping parts
In the progressive die, the shape of the metal stamping part is formed by the periphery of the metal stamping part. The overturning of metal stamping parts is mainly caused by the stretching of the material on the die surface. Therefore, in the blanking process, the pressing and pressing are the keys to prevent the overturning and twisting of the metal stamping parts. Reasons and countermeasures for the deformation of metal stamping parts during the bending process.
Second, the tearing of metal stamping parts
According to the actual production situation, through the inspection of the tearing position, fracture shape and crushing degree, we concluded that the tearing and skewing of the parts are mainly reflected in the flanging forming process, so we need to pay attention to this process, so the resulting The main reasons for this phenomenon are:
- 1. The quality of the workpiece is unstable during the pressing process. The main reason is that the fabrication technicians did not adjust the pressure of the machine tool at the current stage according to the requirements of the process, resulting in stability problems and unstable quality of the workpiece.
- 2. Design defects of flanging forming molds
A mold is a mold with two cavities. Because the content of this process includes not only flanging, but also shape forming. In addition, the product is very complex, the curved surface is narrow, and the molding requires the concave core to be consistent with the molding surface. This leads to the formation of large mold structures and small pressing areas.
