Rivet fasteners (such as knurled rivet nut ) are fasteners that all of us use in our daily lives. Everyone should understand rivet nuts, but when using rivet nuts, this is more than just an understanding. Enough There are many types of rivet nuts, but in fact, many are not much different. Most of them do not differ much in shape, structure, or function. But before using it, what should we pay attention to?
First of all, you need to check whether the spray gun nozzle screw is assembled correctly, select the corresponding spray gun head and rivet according to the size of the rivet nut and whether the connecting piece is firmly connected.
In fact, pay attention to the deformation length or displacement of the rivet nut, and then correctly adjust the opening angle of the operating rod.
Then adjust the riveting stroke with the scale ring of the riveting nut gun. It can be adjusted as needed during operation. It is worth noting that when adjusting the length of the rivet, it is necessary to open the two handles and adjust the gun head sleeve. The exposed length of the rivet bolt is slightly longer than the length of the rivet nut. Finally, tighten the adjusting nut and the gun body.
Finally, open both hands to pull out all the bakelite, put the corresponding rivet nut on the end of the rivet bolt and pinch it firmly, push the bakelite to tighten the gun head bolt, and then pierce the rivet nut into the pre-drilled hole. Press the two handles firmly. At this time, the rivet nut expands to rivet the workpiece, then the bakelite ball is pulled out, and the rivet bolt is pulled out of the threaded hole. It can complete the device of rivet nut.
Therefore, we still need to pay attention to these before using knurled rivet nuts and other rivet fasteners .
