The processing difficulty of automotive stamping parts mainly includes the following aspects:

1. Parts with complex shapes: Automotive stamping parts usually have complex shapes, such as protrusions, grooves, bends, etc., and the metal sheet needs to be stamped into the required shape through a stamping process. Due to the complex shape, the material’s properties such as stretchability and strength need to be considered during the stamping process to ensure the dimensional accuracy and quality of the finished parts.

2. Material selection and processing: Stamping parts usually use metal materials such as steel plates and aluminum alloys. The selection and processing of materials have an important impact on the difficulty of processing. Different materials have differences in mechanical properties, processing performance, corrosion resistance, etc. It is necessary to select appropriate materials according to the specific requirements of the parts, and perform pretreatment, annealing and other processes on the materials to improve processing efficiency and quality.

3. Mold design and processing: The processing of stamping parts requires the design and manufacture of suitable molds. The design of molds includes blanking dies, bending dies, forming dies, etc. Factors such as the shape, size, and process requirements of the parts need to be considered to ensure the processing accuracy and surface quality of the parts. The processing accuracy and durability of the mold have an important impact on the processing quality and production efficiency of stamping parts.

4. Process control and adjustment: The processing of stamping parts requires process control and adjustment to meet the processing requirements of the parts. Process control includes material pretreatment, mold installation and debugging, stamping process parameter setting, etc. Each link needs to be strictly controlled to ensure the dimensional accuracy, surface quality and production efficiency of the parts.

To sum up, the processing difficulty of automotive stamping parts is mainly reflected in the complex shape of the parts, material selection and processing, mold design and processing, and process control and adjustment. Only through scientific process design and strict quality control can the processing quality and production efficiency of stamping parts be guaranteed.
