Suzhou mechanical vibration sheet metal processing machinery effect of the different products according to different cost considerations and the choice of material, typically cold-rolled plate (SPCC), hot-rolled sheet (of SHCC), galvanized sheet (SECC, SGCC), aluminum (aluminum profile), Stainless steel (mirror, brushed surface, matte).
Sheet metal processing materials selection:
1. The cold-rolled plate SPCC with a material thickness of ≤3.2 mm is selected for electroplating and baking paints, because of its low cost and easy molding. The hot-rolled sheet SHCC, because of its low cost, can also be used for electroplating and paint-painting parts, but it is difficult to form, so it is mainly used for flat parts.
2. Galvanized sheet SECC, SGCC. SECC electrolysis board is divided into N material and P material. N material is not used for surface treatment and the cost is high. P material is used for spraying parts.
3. The conductive material is mainly made of copper, which has a high cost because its surface treatment is nickel plating, chrome plating, or no treatment.
4. Aluminum plate, silver plated, nickel plated. Generally used surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost.
5. Due to the complex cross-section structure of aluminum materials, it is suitable for inserting boxes and surface treatment with aluminum plates.
6. Stainless steel without any surface treatment, but its high cost.
Sheet metal processing precautions:
1. Sheet metal processing facilitates the saving of materials.
2. Reasonably select the gap and edge wrapping method, T=2.0 or less gap 0.2, T=2-3 gap 0.5, and the edge wrapping method uses the long edge packet short edge (doorboard type).
3. Reasonable consideration of tolerances Dimensions: negative difference to go to the end, positive difference to take half; hole size: positive difference go to the end, negative difference to go half.
4. Pay attention to the direction of the glitch.
5. Sections should be drawn drawing, riveting, tearing, bumps (bags), and other position direction.
6. Check material, plate thickness, and plate thickness tolerances.
7. Special angle, inner radius of bending angle (general R=0.5).
8. Similar asymmetry should be highlighted.
9. Zoom in on a larger area.
10. If you need to spray protection place must be clear.
