A rivet gun, also known as a rivet hammer or a pneumatic hammer, [1] is a type of tool used to drive rivets. The rivet gun is used on rivet's factory head (the head present before riveting takes place), and a bucking bar is used to support the tail of the rivet. The energy from the hammer in the rivet gun drives the work and the rivet against ...
Many materials can be riveted together using orbital riveting machines including delicate and brittle materials, and sensitive electrical or electronic components. The orbital riveting process uses a forming tool mounted at a 3 or 6° angle. The forming tool contacts the material and then presses it while rotating until the final form is achieved.
The holes being aligned, a rivet is passed through the holes and permanent heads are formed onto the ends of the rivet utilizing hammers and forming dies (by either cold working or hot working). Rivets are commonly purchased with one head already formed. When it is necessary to remove rivets, one of the rivet's heads is sheared off with a cold ...
The self-pierce rivet fully pierces the top sheet material(s) but only partially pierces the bottom sheet. As the tail end of the rivet does not break through the bottom sheet it provides a water or gas-tight joint. With the influence of the upsetting die, the tail end of the rivet flares and interlocks into the bottom sheet forming a low ...
The use of sheet metal, through a comprehensive cold working process, including bending, shearing, punching, laser cutting, water jet cutting, riveting, splicing, etc. to make the final product we want (such as computer chassis, washing machine shells, refrigerator door panels, etc.), we generally called sheet metal fabrication. The academic ...
Clinching phases. In metalworking, clinching or press-joining is a bulk sheet metal forming process aimed at joining thin metal sheets without additional components, using special tools to plastically form an interlock between two or more sheets.
