Riveting is still one of the main methods used in the aircraft assembly industry and other light structure industries where high-strength metal plates cannot be welded. Because of its unique riveting method.
The main reasons for the riveting method are as follows: low installation cost, low hole preparation requirements, high reliability, high strength joints brought by light weight and light weight, and fatigue resistance brought about by high elasticity and high durability.
How to choose the material of rivets? Generally speaking, the material of the same hardness is selected according to the use scene. If it is used on aluminum alloy, it needs to choose aluminum rivets. If it is used on stainless steel, it is generally necessary to choose a relatively high-strength stainless steel material. Above.
The size of the rivet can also refer to the following content.
The diameter of the rivet is at least three times the thickness of the thickest sheet to be connected. According to military standards, the diameter of the flat head of the riveting joint must be 1.4 times larger than the diameter of the drill pipe. The height must extend to 0.3 times the diameter of the drill pipe. You can use all the mentioned parameters to calculate the required rivet length. The tolerance is usually 1.5D.
For example, riveting two plates with a total thickness of A (mm) together. The applicable rivet diameter should be 3 xA = 3A (mm).
Therefore, rivets with a diameter close to 3A (mm) should be used. The metal thickness is 2A (mm), 1.5D is 4.5A (mm), so the total length of the rivet must be 2A+4.5A=6.5A(mm).
