Ensure the quality of sheet metal parts

03-02

In the manufacturing process of precision sheet-metal enclosures, the quality of the sheet metal is of paramount importance, as numerous factors can influence product quality. Therefore, to ensure product quality, it is essential to pay close attention to many details in the fabrication of sheet-metal housings:

1. Select different material-cutting methods based on the specific development drawings and production batches.

2. After the sheet metal enclosure parts have been cut to size, each workpiece is processed according to its specific requirements.

3. Proceed to the corresponding process step. During bending, first determine the tools and die cavities to be used based on the scale and thickness specified in the drawing. Selecting the appropriate upper die is critical to prevent deformation caused by collision between the workpiece and the tooling; the choice of the lower die, in turn, depends on the sheet thickness.

4. Second, determine the sequence of bending operations. The general rules are: bend inward before outward, small radii before large radii, and special features before standard ones.

5. During riveting, the stud height should be taken into account; select both matching and non-matching dies, then adjust the press pressure accordingly.

6. Welding: including TIG welding, spot welding, CO₂ shielded metal arc welding, and manual arc welding. For spot welding, the welding direction for the sheet-metal enclosure should be determined first, and positioning fixtures should be designed for mass production to ensure accurate spot-weld positioning.

7. Surface Treatment: The surface treatment method varies depending on the type of sheet material. Electroplating is typically performed after cold-rolled sheet processing, and no subsequent spray coating is applied. If phosphating is selected, spray coating is applied after phosphating. For electroplated sheets, the surface must be thoroughly cleaned and degreased before spray coating.

8. After spraying is complete, proceed to the installation stage. Throughout this process, wear gloves to prevent dust from adhering to the workpieces; for certain components, use an air gun to clean them.

9. After assembly is complete, proceed to the packaging stage: inspect the workpiece and then place it in a dedicated protective bag for safeguarding.

With the continuous upgrading and advancement of production equipment, the vast majority of forming processes are now carried out on automated machinery. Manual methods are typically employed for complementary operations such as finishing and precision machining. However, in single-piece production or when dealing with parts of complex geometries, manual operations and machining remain indispensable. When manual forming of sheet-metal components is performed using simple tire-forming tools, contour-following fixtures, and zero-point clamping systems, the following techniques should be utilized: bending, edge standing, edge sealing, edge drawing, arch bending, hemming, and weld correction, among others.
