Good manufacturability and reasonable process plan of automobile stamping parts

Good manufacturability and reasonable process plan of automobile stamping parts


In the long-term use of automobile stamping and processing molds, wear or loose fittings will also lead to product scrapping. There are many stamping factories that do not carry out routine inspection and maintenance of the mold after the mold is installed for production. Only when the burr is relatively large, the mold is removed and the knife is simply sharpened. As everyone knows, the wear of the mold is not only the wear of the knife edge, but also some mold parts will wear with use. After these parts are worn, it will affect the accuracy of the entire mold.


The manufacturability of blanking parts refers to the adaptability of blanking parts to the process of blanking. Under normal circumstances, what has a greater impact on the manufacturability of precision sheet metal is the structural shape, precision requirements, shape and position tolerances and technical requirements of the parts. Whether the manufacturability of the blanking parts is reasonable or not will affect the quality of the middle-cutting parts, die life, material consumption, and precision sheet metal productivity. The design should improve its manufacturability as much as possible.

The structure and process of the blanking piece The shape of the blanking piece should be as simple as possible, symmetrical, and avoid complex-shaped curves. When permitted, the blanking piece should be designed into a shape with less and no waste layout to reduce waste. The two ends of the rectangular hole should be connected by Fengdongli car to facilitate mold processing. At the junction of each straight line or curve of the blanking part, sharp corners should be avoided as much as possible, and sharp corners are strictly prohibited. Except when there is little and no waste layout or when using inlay mold structure, there should be proper fillet connection to facilitate mold manufacturing and improve mold life.


The precision sheet metal process design mainly includes two aspects: the process analysis of the blanking parts and the determination of the intermediate cutting process plan. Good manufacturability and reasonable process plan can use small material consumption, small number of processes and man-hours, and stably obtain high-quality crystals that meet the requirements, and make the mold structure simple and long mold life, which can reduce labor and Blanking costs.
