Process flow of sheet metal fabrication.
Selection of sheet metal fabrication materials
The materials commonly used in sheet metal fabrication are cold-rolled sheet (SPCC), hot-rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (CU) brass, red copper, beryllium copper, aluminum sheet (6061, 5052, 1010, 1060, 6063, duralumin, etc.), stainless steel (mirror surface, brushed surface, matte surface), according to the different functions of the product, the materials used for sheet metal fabrication are different, and generally need to be considered from the use and cost of the product.
1. Cold-rolled sheet SPCC, mainly used for electroplating and baking paint, low cost, easy to form, material thickness ≤ 3.2mm.
2. Hot-rolled sheet SHCC, material T ≥ 3.0mm, also uses electroplating, paint parts, low cost, but difficult to form, mainly flat parts.
3. Galvanized sheet metal SECC, SGCC. SECC electrolytic sheet is divided into N-material and P-material. N-material is mainly used for surface treatment, which is expensive, and P-material is used for sprayed parts.
4. Copper; it is mainly used for conductive materials and its surface treatment is nickel-plated, chrome-plated or untreated and its price is high.
5. Aluminum sheet; surface chrome plating (J11-A), oxidation (conductive oxidation, chemical oxidation), high price, silver plating, nickel plating are generally used.
6. Aluminium profiles; materials with complex cross-sectional structure, widely used in various subdivisions. Surface treatment is the same as that of aluminium plate.
7. Stainless steel; mainly used without surface treatment, high cost.
Sheet Metal Fabrication Drawing Review
To write the process flow of sheet metal fabrication parts, you must first know the various technical requirements of the part drawing; then the review of the sheet metal fabrication drawing is the most important link in the compilation of the part process flow.
1. Check that the sheet metal fabrication drawings are complete.
2. The relationship between drawings and views, whether the marking is clear and complete, and marking the unit of measure.
3. Assembly relationship, assembly requires key dimensions.
4. The difference between the old and new layout of sheet metal fabrication.
5. Translation of sheet metal fabrication drawings in foreign languages.
6. Table code conversion.
7. Sheet metal fabrication drawing problem feedback and burial.
8. Material.
9. Sheet metal fabrication quality requirements and process requirements.
10. Sheet metal fabrication officially issued drawings must be stamped with a quality control seal.
