Blind rivet nuts, also known as rivet nuts, pull caps, and instant pull caps, are used in the fastening fields of various metal plates, pipes and other manufacturing industries. They are currently widely used in automobiles, aviation, railways, refrigeration, elevators, switches, instruments, and furniture. , decoration and other electromechanical and light industrial products assembly. It is developed to solve the shortcomings of thin metal plates and pipe welding nuts that are easy to melt and teeth are easy to slip when tapping internal threads. No need to tap internal threads, weld nuts, or rivets. High efficiency and easy to use.

The purpose and working principle of blind rivet nuts

If the nut of a certain product needs to be installed outside, and the internal space is so small that the indenter of the riveting machine cannot enter for riveting, and the strength requirements cannot be met using methods such as crimping, then riveting and expansion jointing are not possible. OK. It must be riveted. It is suitable for fastening plates and pipes of various thicknesses (0.5mm-6mm). It can be riveted in one time using a pneumatic or manual riveting machine, which is convenient and firm; it replaces the traditional welding nut and makes up for the The disadvantages of welding metal sheets and thin tubes are that they are easy to melt and the welding nuts are not smooth.

Precautions when using blind rivet nuts

1. Check whether the gun nozzle screw is assembled correctly, select the corresponding gun head and rivet nut according to the rivet nut scale, and ensure that the connecting parts are firmly connected.

2. Pay attention to the deformation length or displacement of the riveting nut, and then correctly adjust the opening angle of the operating rod.

3. The calibration ring of the rivet nut gun is used to adjust the rivet stroke, which can be adjusted as needed during operation. It is worth noting that when adjusting the length of the rivet bolt, you need to open 2 handles and adjust the sleeve of the gun head to make the rivet bolt The exposed length is slightly larger than the length of the rivet nut. After that, tighten the adjusting nut and the gun body.

4.z After that, open your hands to pull out all the bakelite, put the corresponding rivet nut on the end of the rivet bolt and clamp it, push the bakelite to screw on the bolt head, and then insert the rivet nut into the pre-drilled rivet piece hole, and then press the two handles together with force. At this time, the rivet nut expands to rivet the workpiece tightly, then pull out the bakelite ball, and the riveting bolt withdraws from the threaded hole. The rivet nut pulling device is completed.
