How is the rivet stud pressed on

Rivet stud is a fastener that is fixed to a plate or other substrate by pressure rather than welding or threading. It is widely used in industries such as sheet metal, electronics, aviation, and automotive, especially in situations where repeated disassembly or limited space is required. The following is a detailed explanation of how rivet bolts are pressed into the substrate:

The structure of rivet bolts

Rivet studs are usually composed of two parts: the body and the rivet foot (also known as the flange). The cylindrical part is a straight rod with or without threads, used for screwing in screws or other accessories. The rivet feet are located at one end of the bolt, and when subjected to sufficient pressure, these rivet feet will be squeezed and folded, forming a sturdy connection.

Riveting process

Preparation work: Firstly, it is necessary to select the appropriate size of rivet bolts based on the thickness and material of the board. Next, drill holes on the board with a diameter slightly smaller than the diameter of the bolt to ensure that the bolt can be tightly embedded in the board.

Positioning: Thread the rivet bolt through the hole in the board, ensuring that the axis of the bolt is perpendicular to the board.

Apply pressure: Use specialized riveting tools (such as hydraulic riveting guns, pneumatic riveting guns, etc.) to align the rivet feet of the bolts. The head of the riveting tool is usually designed with grooves or special shapes to ensure that the rivet feet can be evenly folded outward when pressure is applied.

Flanging forming: When the pressure reaches a certain level, the rivet foot will flip outward under the action of the riveting tool, forming a shape similar to a "mushroom head". This flange will tightly press against the back of the board, forming a stable connection. In this process, the frictional force between the board and the screw, as well as the clamping force of the flange, work together to firmly fix the screw on the board.

Inspection: After the riveting is completed, check whether the bolts are firmly fixed on the board and whether there is any looseness or incomplete flanging. If necessary, re riveting or other remedial measures can be taken.

matters needing attention

When selecting rivet bolts, factors such as the material and thickness of the board, as well as the load-bearing capacity of the bolts, need to be considered.

It is very important to use appropriate riveting tools, as improper tools may cause damage to the bolts or incorrect installation.

Apply pressure evenly, as excessive pressure may cause deformation of the board or damage to the bolts.

For certain special materials or occasions, it may be necessary to use specially designed rivet bolts or rivet tools.

By following the above steps, the rivet bolt can be successfully pressed into the board or other substrate, forming a reliable connection. This method is not only easy and fast to operate, but also provides good fixing effect, which is very suitable for application scenarios that do not allow the use of welding or threaded connections.
