The process design of precision sheet metal mainly includes the process analysis of blanking parts and the determination of blanking process plan. With good processability and reasonable process plan, we can use small material consumption, less working procedure quantity and working hours to obtain high-quality crystalline products that meet the requirements stably, and make the die structure simple and die life high, so we can reduce labor and blanking cost.

The technological property of blanking parts refers to the adaptability of blanking parts to hedging process. In general, the structural shape, accuracy requirements, form and position tolerance and technical requirements of the parts have a great influence on the precision sheet metal technology. Whether the process of blanking parts is reasonable or not will affect the quality of blanking parts, die life, material consumption, precision sheet metal production rate, etc. in the design, the process should be improved as much as possible.

The shape of the structural technological blanking part of the blanking part shall be as simple as possible, symmetrical and avoid the curve of complex shape. If permitted, the blanking part shall be designed into the shape of less and no waste layout to reduce the waste The two ends of the rectangular hole should be connected by circular arc to facilitate mold processing. Sharp corners shall be avoided as far as possible at the connection of straight lines or curves of blanking parts, and sharp corners are strictly prohibited. In addition to less, no waste layout or the use of panel die structure, there should be appropriate fillet connection, in order to facilitate mold manufacturing and improve the life of the mold.

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

When the welding slag is removed by enemy strike, it is strictly forbidden to look at it directly with naked eyes, and the eyes shall be properly shielded. No naked eye welding is allowed at any time. Keep the working room ventilated and weld in the closed environment or sealed container. Corresponding air supply measures must be taken and special personnel shall be responsible for supervision.

The welding of the pressure vessel of the dangerous goods transport vehicle must be approved by the hot work, and the storage tank shall be digested, cleaned and replaced according to the requirements. The operation can only be carried out under the supervision of a specially assigned person after the inspection and confirmation. Clean the operation site at any time, put the workpieces regularly, and stack the welding slag in a safe place to prevent scalding and fire hazard.
