Precision automotive sheet metal parts are the basic process equipment for sheet metal fabrication

Precision sheet metal process design mainly includes process analysis of blanking parts and determination of blanking process plan. Good manufacturability and reasonable process plan can stably obtain high-quality crystals that meet the requirements with small material consumption, less number of processes and man-hours, and make the mold structure simple and mold life long, so it can reduce labor and labor. Blanking costs.

The manufacturability of blanking parts refers to the adaptability of blanking parts to the blanking process. Under normal circumstances, the structural shape, precision requirements, geometric tolerances and technical requirements of the workpiece are the most important factors affecting the craftsmanship of precision sheet metal. Whether the craftsmanship of the blanking parts is reasonable or not affects the quality of the blanking parts, the life of the die, the consumption of materials, the productivity of precision sheet metal, etc. The craftsmanship should be improved as much as possible in the design.

The shape of the blanking parts should be as simple as possible, symmetrical, and avoid complex shapes of curves. If permitted, the blanking parts should be designed into a shape with less and no waste layout to reduce waste. Both ends of the rectangular hole should be connected with arcs to facilitate mold fabrication. At the connection of the straight lines or curves of the blanking parts, try to avoid sharp angles, and sharp angles are strictly prohibited. Except in the case of less and no waste layout or the use of a mosaic structure, appropriate rounded corners should be connected to facilitate mold manufacturing and improve mold life.

Precision automotive sheet metal parts are the basic process equipment for sheet metal fabrication. The surface quality, precision sheet metal dimensional accuracy, productivity, and economic benefits of sheet metal stamping parts depend on the rational design and manufacture of the die structure. Therefore, at present, the die design and manufacture are developing in the following three directions.

When the enemy strikes to remove the welding slag, it is strictly forbidden to look directly with the naked eye, and the eyes should be properly shielded and protected. Welding should not be performed with naked eyes at any time. Keep the workshop ventilated, and welding in a closed environment or a sealed container must take corresponding air supply measures and have a special person responsible for supervision.

Welding of pressure vessels of dangerous goods transport vehicles must be approved for hot work, and the storage tanks should be cooked, cleaned and replaced as required. After inspection and confirmation, the operation can be carried out under the premise of special supervision. Clean up the job site at any time, place workpieces regularly, and pile up welding slag in a safe place to prevent burns and fire hazards.
