Cales son os parafusos e porcas de remache comúns?

Sheet metal is an important part of modern industry. Sheet metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. Medical equipment and other fields have been widely used, and the connection of sheet metal is the most widely used in addition to welding, riveting, riveting is divided into detachable riveting and non-detachable riveting, detachable riveting needs to open bottom holes in the metal sheet During pressure riveting or pull riveting, two metal sheets can be connected by screws.

The following are the relevant parameters corresponding to several common riveting forms:

1. Pressure riveting nut:

The rivet nut is also called a rivet nut, a self-tightening nut, which is a kind of nut applied to a thin plate or sheet metal. The principle is to press the embossed teeth into the preset holes of the sheet metal. Generally speaking, the diameter of the preset holes is slightly smaller than the embossed teeth of the pressure riveting nut. The periphery of the hole is plastically deformed, and the deformed object is squeezed into the guide groove, thereby producing a locking effect.

2. Pressure riveting nut column:

The principle of the pressure riveting nut is basically the same as that of the pressure riveting nut.

3. Pressure riveting screws:

It is a new type of fastener applied to thin plate or sheet metal. The principle is to press the embossed teeth into the preset holes of the sheet metal. The diameter of the general preset holes is slightly smaller than the outer diameter of the pressure riveting screw. The periphery of the hole is plastically deformed, and the deformed object is squeezed into the guide groove, thereby producing a locking effect.

The press riveting process is similar to the process of press riveting nuts.

4. Rivet nuts:

Pull riveting refers to the plastic deformation of the riveted parts under the action of external tension during the riveting process. The commonly used rivet nuts are connected with the base material by this type of riveting. Pull riveting uses a special riveting gun for riveting, which is mostly used when the installation space is small and general riveting tooling cannot be used.
