Aerospace metal stamping is a high-precision, high-quality metal forming process that is widely used in the aerospace industry. This process applies pressure to a sheet of metal through a die, causing it to deform plastically to obtain the desired shape and size. The following is a detailed description of aerospace metal stamping.
1. Aerospace metal stamping production process
Preparation of blanks
Definition of flat parts: Determine the specifications and material of the required sheet metal.
Unloading: Use laser cutting, EDM wire cutting, etc. to cut the sheet metal into blanks of the required shape and size.
Layout: Reasonably arrange the layout of blanks on the metal sheet to optimize material utilization.
Stamping process preparation
Processability evaluation: Evaluate the stamping performance of the metal sheet and determine the appropriate stamping process parameters.
Tooling design: Design and manufacture stamping tooling according to product shape and size.
Process Layout: Reasonable arrangement of equipment, molds and process flow in the stamping shop.
Stamping forming
Stretching: Stretching the blank through the die to form the desired shape.
Trimming: Remove the excess produced in the stamping process, so that the product reaches the required size and shape.
Shaping: Fine-tuning of the stamped and formed product to ensure its shape and dimensional accuracy.
Quality Inspection
Strict quality inspection is carried out on the stamped and formed products, including size, shape, surface quality and other aspects.
Subsequent processing
According to the requirements of the products, surface treatment such as spraying and plating are carried out to improve the corrosion resistance and aesthetics of the products.
