(1) Selection of sheet metal parts processing materials:
Sheet metal processing materials commonly used are cold rolled sheet (SPCC), hot rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (CU) brass, red copper, beryllium copper, aluminum plate (6061, 6063, hard aluminum, etc.), aluminum profiles, stainless steel (mirror, drawing surface, fog surface), according to the different role of the product, the selection of materials, Generally, the use and cost of the product should be considered.
1, cold rolled SPCC, mainly used in electroplating and paint parts, low cost, easy to form, material thickness ≤3.2mm.
2, hot rolled plate SHCC, material T≥3.0mm, also use electroplating, paint parts, low cost, but difficult to form, mainly use flat parts.
3, galvanized sheet SECC, SGCC. SECC electrolytic plate N material, P material, N material is not mainly surface treatment, high cost, P material for spraying parts. 4, copper; Mainly with conductive materials, its surface treatment is nickel plating, chromium plating, or no treatment, high cost.
5, aluminum plate; General surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.
6, aluminum profile; Materials with complex cross section structure are widely used in various boxes. Surface treatment with aluminum plate.
7, stainless steel; Mainly used without any surface treatment, high cost.
(2) Sheet metal parts processing drawing review
To write parts of the process flow, first of all to know the parts of the various technical requirements; Drawing audit is the most important part of the preparation of parts process flow.
1. Check whether the drawing surface is complete.
2, drawing view relationship, labeling is clear, complete, labeling size units.
3, assembly relationship, assembly requirements of key dimensions.
4, the difference between the new and old version of the drawing.
5. Translation of foreign drawings.
6, table code conversion.
7, drawing problem feedback and buried.
8, the material
9. Quality requirements and process requirements
10. Quality control seal shall be affixed to the officially issued drawing.
