What is the Technological Process of Sheet Metal Processing?

As a Sheet Metal CNC Stamping Processing Supplier, share it with you.

Sheet metal processing is a hub technology that sheet metal technicians need to grasp, and it is also an important process in sheet metal product forming. Sheet metal processing includes traditional cutting, blanking, bending and forming methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operating methods, and new stamping technologies And new technology. Parts sheet metal processing is called sheet metal processing.

Sheet Metal CNC Stamping Processing

Material selection

The materials generally used in sheet metal processing are cold rolled plate (SPCC), hot rolled plate (SHCC), galvanized plate (SECC, SGCC), copper (CU) brass, red copper, beryllium copper, aluminum plate (6061, 5052) 1010, 1060, 6063, duralumin, etc.), stainless steel (mirror, brushed, matte), depending on the role of the product, different materials are used, and generally need to be considered from the product's use and cost.

1. Cold-rolled sheet SPCC, mainly used for electroplating and baking varnish parts, low cost, easy to shape, material thickness ≤ 3.2mm.

2. Hot-rolled sheet SHCC, material T≥3.0mm, also uses electroplating, baking varnish parts, low cost, but difficult to form, mainly flat parts.

3. Galvanized sheet SECC, SGCC. SECC electrolytic board is divided into N material and P material. N material is mainly used for surface treatment and high cost. P material is used for sprayed parts.

4. Copper; mainly uses conductive material, and its surface treatment is nickel plating, chrome plating, or no treatment, which is costly.

5. Aluminum plate; generally use surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.

6. Aluminum profiles; materials with complex cross-section structures are widely used in various sub-boxes. The surface treatment is the same as the aluminum plate.

7. Stainless steel; mainly used without any surface treatment, high cost.

Drawing review

To compile the process flow of a part, we must first know the various technical requirements of the part drawing; then the drawing review is the most important link in the compilation of the part process flow.

1. Check whether the drawing is complete.

2. The relationship between the drawing and the view, whether the marking is clear and complete, and the unit of dimension is marked.

3. The assembly relationship, the assembly requires key dimensions.

4. The difference between the old and new version of the graphics.

5. Translation of pictures in foreign languages.

6. Code conversion at the table.

7. Feedback and disposal of drawing problems.

8. material.

9. Quality requirements and process requirements.

10. The official release drawings must be stamped with a quality control seal.
