Characteristics and forming precautions of electronic stamping parts

Electronic stamping products have their peculiar characteristics in daily processing:
The number of processes in electronic stamping parts processing is related to the properties of the material, the stretching height, the stretching path, the pulling diameter, and the thickness of the material;
2. The flushing process of electronic stamping parts includes chemical flushing methods such as alkaline solution flushing, solvent flushing, surfactant flushing, etc;
3. The adhesion between the coating of electronic stamping parts and the substrate is a crucial factor in ensuring the quality of electroplated products. Before electroplating, the substrate material may have various contaminants on its surface, such as cutting fluid, lubricant, polishing paste, etc. The cleanliness of the surface of the substrate material directly affects the adhesion of the electroplating layer, and surfaces with oil stains must be rinsed.
Electronic stamping parts are mostly used in multifunctional digital or household appliances. Due to the relatively small size of the parts, what should we pay attention to when forming?
1. The internal R radius in the forming position of electronic stamping parts should not be too large, as it not only undergoes plastic deformation but also elastic deformation. If the internal R is large, the rebound will increase and it cannot ensure the consolidation of the forming angle;
2. The circular arc of the forming punch should not be too small. If the forming angle of the punch is small, it is easy to scratch the outer side of the material. For ordinary soft materials, it is very low at twice T, and for hard materials, it cannot be lower than 1.5-2T;
3. The formed straight edge cannot be too short. In order to ensure the relationship between the forming position and angle of electronic stamping parts, although the formed straight section is made high, it should not be lower than 2T when it is very low;
4. If the position of the forming and the hole is relatively close, in order to ensure that the hole is not easily deformed and also ensures accuracy, although it needs to conform to the relationship between the forming inner fillet r and the plate thickness t (t<2, 1 ≥ r+t; t ≥ 2, 1 ≥ r+2t)
