Manufacturability in the processing of bending stamping parts

1. When the stamping part is processed and bent, when the bending fillet exceeds the ultimate strength of the material, cracks and breaks will occur, and too small bending fillet radius should be avoided; 2. The setting of R angle should not be greater than 1.5 Times the material thickness. Because the R angle is too large, the springback will also be large after bending; 3. When the bending stamping parts are processed, the bending height should not be too long, and H should not be too small, especially when the material t>2mm, H will be too small. It will make it difficult to bend, and it is difficult to obtain stamped parts with accurate shapes; when the bending angle of the bending part is 90 degrees, the straight edge height of the bending part should be made h>2t for the convenience of forming. When hu003d1.3t2t, R≈0 or Only use bending methods such as pressing grooves; 4. The bending line of the bending stamping parts should be designed not to be in the place with sudden width changes to avoid tearing; if it is necessary to design in the place with sudden width changes, it can be pre-punched in the width sudden change. Process hole or process slot; 5. For curved stamping parts with holes, if the hole is located near the bend, the hole will be deformed when bent; 6. When the bent stamping part is composed of two parts, the width and the narrow part, transition the outer distance L≥R; 7. For the bending of symmetrical parts, the left and right bending radii should be consistent to ensure the balance of forces during the bending process to prevent sliding during the bending process; 8. When designing the bending stamping parts, due to the curved shape And the shape of the overall stamping part is irregular, so it is necessary to design the reference hole or reference edge and some benchmarks for marking the tolerance on the stamping part; 9. When designing the bending stamping part, the length of the material expansion before bending should be considered ( Orientation) Is there enough aperture (distance between two pieces>t); Recommended article: In the process of processing stamping parts, what should be paid attention to when feeding?
