Strength required for connection
First, determine the tensile strength and shear strength required by a single nail at the connection position of the workpiece on the panel of the sheet metal part. The cost of a single product can be calculated according to the total connection strength required by the workpiece and the number of cloth riveting cuts. The diameter of the rivet, the material of the rivet body, and the style of the nail will have an impact on the strength. After the standard is determined,At present, the strongest structural rivets are BOM nails, also known as BMW nails. As high-strength structural rivets, BOM nails are the ideal choice for single sided installation that requires high loads. BOM nails can meet the requirements of various conventional diameters and clamping ranges from 4.8mm to 19,1mm. Unlike traditional physical diagnosis, which uses torque rotation to generate anchoring force, BOM locks (BULB LOCK) use unique ring frequency tightening and ring German breaking force technology, and under external tension, The stretching nail rod compresses the nail sleeve to produce plastic deformation, and the BOM nail's shipboard connection structure achieves reliable and tight connection by clamping the substrate at the deformed part. It has high tightening force and high resistance to third forces, fundamentally solving the problem of ordinary fasteners loosening under vibration conditions. At the same time, it has higher accuracy and production efficiency. Excellent vibration resistance.
The thickness of the riveted object
Measurement is the total thickness of the workpiece that needs to be riveted. Select a rivet specification that can cover the working thickness in the riveting range. If the rivet length is insufficient, it will not be able to form sufficient blind surface support on the back of the workpiece correctly, which will lead to unstable riveting.
Material of the object being connected
The material of the rivet itself and the material of the fixed workpiece will both affect the final connection leakage. Usually, the nail material should have physical and mechanical properties that are the same or similar to the material of the fixed workpiece. Due to significant material differences, riveting failures caused by material fatigue or electrical corrosion may occur
Size of drilling holes
It is important to match the drilling size with the rivet size. If the hole is too small, it will make it difficult to insert the rivet. If the hole is too small, it can cause poor riveting or even rivet detachment. You can refer to the "Drill Hole Size" column on the Ficus rivet sample to select a suitable product or drilling size. If the size is non-standard, please contact our sales engineer for professional advice.
Selection of nail head type
(generally including round head, countersunk head, large edge, etc.)
Round headed steel nails are suitable for most field policies. However, when it is necessary to fix soft or easily degradable materials to rigid panel components, consideration should be given to using large brim rivets larger than the image head, which provide twice the contact surface of a regular mesh head. If you need a flat surface after riveting, you can choose to use countersunk rivets with countersunk drilling.
