In order to meet the requirements of product functions and appearance, the design of sheet metal should ensure that the stamping process is simple, the production of stamping dies is easy, the quality of sheet metal stamping is high, and the dimensions are stable. For detailed sheet metal design guidelines, please refer to "Part Structure Design Processability" and "Product Design Guide for Manufacturing and Assembly" published by the Machinery Industry Press.

process

After the drawing is in hand, different blanking methods are selected according to the development plan and the batch. Among them are laser, CNC punching, shearing plate, mold and other methods, and then the corresponding development is made according to the drawing. CNC punches are affected by tools. For some special-shaped workpieces and irregular holes, large burrs will appear on the edges. Later deburring should be performed, and at the same time, the accuracy of the workpiece will be affected to some extent. Laser processing has no tools. Limitation, flat cross-section, suitable for processing special-shaped workpieces, but it takes longer to process small workpieces. Placing a table next to the CNC and the laser will help the sheet to be placed on the machine for processing and reduce the workload of lifting the board.

Some scraps that can be used are placed in designated places to provide material for the trial mold during bending. After the workpiece is blanked, the corners, burrs, and contacts need to be trimmed (grinded). At the tool contact, use a flat file to trim. For workpieces with larger burrs, use a grinder to trim, and the small inner hole contact The corresponding small file is used for trimming to ensure the beautiful appearance. At the same time, the trimming of the shape also guarantees the positioning during bending, so that the workpiece is placed on the bending machine at the same position during bending to ensure the same size of the same batch of products.
