Precision sheet metal process design mainly includes two aspects: process analysis of blanking parts and determination of the blanking process plan. Good craftsmanship and reasonable process plans can stably obtain high-quality products that meet the requirements with small material consumption, small number of processes and working hours, and make the mold structure simple and the mold life long, thus reducing the amount of labor and Blanking costs.

The craftsmanship of the blanking parts refers to the adaptability of the blanking parts to the punching and hiding process. Generally speaking, the structural shape, accuracy requirements, geometric tolerances and technical requirements of the parts have a greater impact on the processability of precision sheet metal. Whether the craftsmanship of the blanking parts is reasonable or not affects the quality of the blanking parts, mold life, material consumption, precision sheet metal productivity, etc. The craftsmanship should be improved as much as possible in the design.

The shape of the punched parts should be as simple and symmetrical as possible, avoiding complex curves. If possible, the punched parts should be designed with less and no waste to reduce waste. The two ends of the rectangular hole should be connected with arcs to facilitate mold processing. Try to avoid sharp angles at the joints of straight lines or curves in the blanking parts, and sharp corners are strictly prohibited. Except when laying out with little or no waste or using an inlaid mold structure, there should be appropriate rounded corners to facilitate mold manufacturing and increase mold life.

Precision automotive sheet metal parts are the basic process equipment for sheet metal processing. The surface quality, precision sheet metal dimensional accuracy, productivity, and economic benefits of sheet metal stamping parts all depend on the reasonable design and manufacturing of the die structure. Therefore, die design and manufacturing are currently developing in the following three directions.

When removing welding slag, it is strictly forbidden to look directly with naked eyes, and the eyes should be properly shielded and protected. No open hole welding is allowed at any time. Keep the workplace ventilated. When welding is performed in a closed environment or sealed container, appropriate ventilation measures must be taken and a dedicated person must be responsible for supervision.

The welding of pressure vessels of dangerous goods transport vehicles must be approved by fire, and the storage tanks must be boiled, cleaned and replaced as required. Only after inspection and confirmation that they can be operated can they be operated under the supervision of a dedicated person. The work site should be cleaned at all times, workpieces should be placed regularly, and welding slag should be piled in a safe location to prevent burns and fire hazards.
