Basic process sequence of sheet metal processing 3
Pressure riveting: refers to the process of firmly crimping fasteners such as pressure riveting nuts, pressure riveting screws or pressure riveting nut columns on the workpiece by using a punching machine or a hydraulic machine. Normally, the direction of loading the riveting parts is the direction of the burr, so that the riveting parts can be loaded smoothly. If not, the manufacturer should report it in time.
Expansion riveting: refers to the process of sinking the workpiece first, and then using a punch or hydraulic press to firmly crimp the expansion rivet nut on the workpiece.
Pull mother: refers to the use of a similar riveting process. The process of firmly connecting connecting parts such as rivet nuts (POP) to the workpiece with a puller gun.
Blind riveting: refers to the process of using a riveting gun as a tool to tightly connect two or more workpieces with a rivet.
Riveting: The process of connecting two or more workpieces face-to-face with rivets. For countersunk riveting, the workpieces need to be countersinked first.
