Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic rivet guns, in particular to a portable pneumatic rivet gun. Background Art

[0002] Rivet guns are used for fastening and riveting of various metal plates, pipes and other manufacturing industries. They are widely used in the riveting of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, decoration, etc. They are developed to solve the shortcomings of easy melting of metal sheet and thin tube welding nuts and easy slipping of internal threads. Rivet guns are divided into pneumatic rivet guns, electric rivet guns, manual rivet guns and hydraulic rivet guns according to different power. The working principle of the pneumatic rivet gun is to pass the compressed air from the connecting pipe through the valve to the piston, so that the piston moves back and forth in the rivet gun body, driving the hammer at the front end of the rivet rod to impact the rivet, roughen it and stick it to the wall of the rivet hole to fix the riveted workpiece. Most of the current pneumatic rivet guns need to be equipped with a booster pump to provide sufficient power, which leads to its overall large size and difficulty in carrying, limiting the range of activities of the operator and reducing the overall efficiency of the riveting operation. However, although the integrated simplified equipment reduces the overall volume, it increases the load on the arm and affects the accuracy and stability of hand-held riveting. Utility Model Content
