Rivet application and common sense

Core Tip: Usually riveting is to insert the rivet from one side of the plate, and must be topped with a top iron and then riveted with rivets, but when riveting with a rivet gun | rivet gun, only one side operation is required. Usually riveting is to insert the rivet from one side of the plate, and it must be topped with a top iron and then riveted with a rivet, but when riveting with a rivet gun | rivet gun, only one side operation is required.

Riveting of rivet guns is often used for riveting of the underside of a hand or top iron.

Principle of rivet joint

The rivet is a hollow rivet with a nail stalk at the center. The end of the nail stalk is round-necked and has a scale at the center. The rivet hole is first drilled during the operation, and the rivet is inserted, using manual or pneumatic.

The rivet gun|the rivet gun's collet covers the rivet stem and applies a pulling force to bite the rivet spike. The stalk is stressed, which will force the softer rivet head to expand outward into a flange shape, thereby making the material Tightly bond, and then pull again until the spike is pulled off, the plate can be riveted.

Advantages of rivet joint

Single-direction operation, no noise; the workpiece will not be destroyed; work is light, convenient, and hygienic; labor-saving, time-saving, trouble-saving, and accurate;

Specifications and types of rivets

1. The rivet can be divided into two types: aluminum alloy rivet and stainless steel rivet according to different materials;

2, according to the shape of the rivet nail head, the rivet can be divided into round head rivet and head type rivet;

Rivet selection

It is important to select the appropriate rivet before joining the workpiece with the rivet. The choice of rivet usually follows the following principles:

1. Select the same material pull rivet according to the workpiece material;

2. The joint of general materials is made of aluminum alloy round head Latin;

3. When the surface of the workpiece is required to be smooth, the rivet of the head is used;

4. In places where corrosive substances such as acid are used, stainless steel rivets are used;

5. The diameter, length and thickness of the rivet are selected in the appropriate rivets;

6. The diameter of the material is larger than the diameter of the rivet of about 0.1 mm;

Riveting gun | rivet gun construction

Manual rivet guns can be divided into two types: normal type and strong type. Riveting guns | Rivet gun specifications are based on their length. The rivet gun is equipped with a plurality of nozzles, which are marked with different calibers, and can be used alternately according to actual needs.

The rivet gun has a rivet steel claw piece, which can firmly grasp the rivet nail stalk and press the rivet nail head to make the material close.

At present, the use of pneumatic rivet guns is also more common, and the use of pneumatic rivet guns can save a lot of time and manpower. The action principle is that the compressed air is passed from the connecting pipe to the piston through the connecting pipe, so that the piston reciprocates in the gun body to form the rivet; the air pressure generally used is about 0.1-0.7 m3/min, and a plurality of nozzles are provided. There are different apertures on the top, which can be used alternately according to actual needs.
