What Is a Rivet Gun?

The rivet gun is used for fastening riveting of various metal plates, pipes and other manufacturing industries. It is currently widely used in riveting of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture and decoration . Developed to solve the shortcomings of thin metal plate and thin tube welding nut, easy tapping of internal thread, etc. It can be used for riveting products that do not need to tap internal thread, do not need welding nut, high efficiency and easy to use.

The rivet gun can be divided into: cored rivet gun, rivet nut gun, ring groove rivet gun according to the different rivets installed.

According to the different power: pneumatic rivet gun, electric rivet gun, manual rivet gun, hydraulic rivet gun.

Application of riveting gun: If the nut of a certain product needs to be installed on the outside, and the space inside is narrow, the head of the riveting machine cannot be entered for crimping and the method such as budding cannot meet the strength requirements. Rising is not feasible. Must use riveting to apply to various thickness plates and pipes (0.5MM-6MM) fastening field. Pneumatic or manual riveting gun can be used for riveting at one time, which is convenient and firm; instead of traditional welding nuts, it can make up for thin metal plates, thin

working principle:

Compressed air is passed from the connecting pipe to the piston through the valve to make the piston reciprocate in the rivet gun body, and the ram on the front end of the rivet rod impacts the rivet.

Improve:

Aiming at the situation that the riveting quality of the aviation pneumatic rivet gun is difficult to control and the punch is easy to fly out, an improved pneumatic rivet gun control system design scheme is proposed: wireless communication is used to control the on-off state of the pneumatic input circuit of the rivet gun. To control the riveting process. The results show that this solution can effectively improve the riveting efficiency, riveting quality and the safety factor of the pneumatic rivet gun ^[2]

1. Before starting work, inject a small amount of lubricating oil from the air inlet to ensure the working performance and working life of the rivet gun.

2. Maintain the prescribed intake pressure. If the air pressure is too small, the power of the rivet will be reduced, and not only the efficiency of riveting is low, but the rivet head may also crack due to excessive hammering times.

3. Press the button after the punch is tightened against the rivet. Otherwise, the piston produces a back-and-forth motion, which consumes a part of the energy, and the piston hits the casing, which damages the rivet gun.

4. Use a protective spring to connect the punch to the gun body firmly to prevent the punch from flying out and damaging people or products.

5. Hold the right handle and press the button with your index finger to start the rivet gun. The button can be used to adjust the size of the compressed air to ensure the rivet gun to work smoothly. At the beginning of riveting, because the rivet rod is longer, the gap between the rivet rod and the rivet hole is larger, and the rivet rod is easy to bend when being hammered. Therefore, the button should be pressed lightly to make the rivet gun less powerful. After the rivet rod fills the rivet hole and then press it again, increase the rivet power to quickly form a pier head. When the head is near completion, gradually release the button to prevent the pier head from hit Is too low.

6. The tail of the punch is prepared according to different rivet gun models. It should not be used in series to avoid damage to the parts and reduce efficiency.

7. The gun should not be emptied randomly during use to avoid damage to the parts.

8. It is strictly forbidden to use muzzle on people during use.
