Blind rivets are rivets used for single-sided riveting, but special tools and riveters must be used for riveting. When riveting, a special rivet gun is required to pull the rivet core to expand the rivet body and play a riveting role. It is widely used in Construction, automobiles, ships, aircraft, machines, electrical appliances, furniture and other products.

Precautions when using blind rivets

1. When checking the finished blind rivets, you need to check: the diameter of the rivet body, the length of the rivet rod, the thickness of the rivet body cap, the diameter of the cap, the total length of the rivet core, the exposed size of the rivet core, the size of the rivet cap, The outer diameter after assembly can be considered. In actual inspection, the weak links of the product can be measured, such as tensile strength, shear strength, resistance to falling off of the nail core, etc.

2. The key is to pay attention to the rivets. The rivet feet are insufficient and whether the rivets are in place; or the rivet mouth cannot be pulled off because the rivet core cap is too large; there is also a skipping head, which means that the pulling force of the rivet core is too low or the fracture size is too thin.

3. Rivet material: aluminum, iron, stainless steel, alloy, etc.

4. The total thickness of the workpiece is generally 45%-65% of the rivet length, and try not to exceed 60%. In addition, it is also troublesome if the working length is too short. It is recommended that it should generally be 50%-60%. If the rivet length is too long, the rivet will The head will be too large and the rivet rod will bend easily; if the rivet length is too short, the pier thickness is insufficient, and the nail head is incomplete, the strength and tightness will be affected. Rivets that are too long or too short are not good. Only the right length can achieve good results. riveting effect.
