First, rivet gun classification and model.

The riveting gun is the main equipment for riveting, according to different shapes, can be divided into straight riveting guns, closed riveting guns, pistol-type riveting guns, and curved riveting guns, of which pistol-type riveting guns are most widely used; riveting guns can also be divided into pneumatic, electric, riveting hydraulic guns; according to the different applications, the riveting guns used in different models;

The rivet gun model should be selected according to the rivet material, diameter, and product structure; the rivet gun can use aluminum rivets can generally also use steel rivets, but the diameter of the steel rivets need to be reduced by a corresponding specification than the diameter of aluminum rivets. Usually, hard materials, large diameter rivets should be selected with a large power rivet gun.

The second, the pistol-type rivet gun.

Pistol type rivet gun, also known as the wind gun, mainly by the handle, gun body, switch and pipe fittings, the front of the gun body in the hole, according to the need to install a variety of rivet cover mold or punch, for riveting or nailing operations;

Before using the rivet gun, a small amount of lubricating oil must be injected into the air hose joint in order to maintain good lubrication inside the rivet gun, followed by blowing the dirt out of the compressed air hose and then connecting it to the pipe joint of the rivet gun. The amount of air intake to the air hose can be controlled by means of a pressure regulating flap.

The rivet gun is usually used with a thin wire bolt on the handle to prevent the piston from slipping out of the gun due to the mold being separated from the gun body. The riveting process should be slow and then fast, first, slow in order to upset the nail bar and fill the nail hole, and then fast to complete the rivet header shape. The rivet gun has a small size, easy to operate, can be riveted in a variety of positions and other advantages, but the operation is very noisy.

Third, the wind-powered pull rivet gun.

Pull rivet gun is cold riveting equipment, is the use of 0.6MPa high-pressure air as a power to push the piston within the wind gun rapid back and forth movement, and hit the rivet cover mold installed in the mouth of the wind gun, in the sharp hammering to complete the riveting, wind-powered pull rivet gun is mainly used in hollow rivets and mandrels composed of pull riveting connection;

Pull riveting work, pull rivet gun will be drawn by the core bar of the core bar clamped, and the end of the gun against the rivet head, by pulling the rivet gun backward pull, so that the core bar convex shoulder part of the rivet produced compression deformation, and the formation of rivet head; at the same time the core bar diameter shrinkage is pulled off, the remaining core bar is pulled out. The pull rivet gun is suitable for the connection of light structures.
