Description

Technical Field

[0001] The utility model relates to the technical field of pressure riveting devices, in particular to a pressure riveting device for sheet metal processing. Background Art

[0002] Pressure riveting is a fixing process, also known as a form of riveting. During pressure riveting, under external pressure, the pressure riveted parts cause the body material to undergo plastic deformation and squeeze into the prefabricated grooves specially designed in the riveted screw and nut structure, thereby achieving a reliable connection between the two parts. This process is often used to fix studs on plates such as iron plates and aluminum plates that cannot be welded. It is a very common fixing method. Ordinary low-carbon steel, aluminum alloy plates, and copper plates are suitable for crimping pressure riveted nut columns. For stainless steel and high-carbon steel plates, because of their harder materials, special high-strength pressure riveted nut columns are required. There are two types of non-standard nuts for pressure riveting, one is the pressure riveted nut column and the other is the pressure riveted nut. This type of riveting is used to achieve connection with the base material, and the hardness of the riveted parts is usually required to be greater than the hardness of the base material.
