Rivet nuts are divided into pull rivet nuts and pressure rivet nuts. These two tools are not unfamiliar to industrial workers, but many people are not very clear about the difference between the two and how to choose them.

First of all, let's take a look at the rivet nuts. The rivet nuts mainly contribute to the field of fasteners, and are widely used. They are mainly used in the assembly and assembly of electromechanical and light industrial products such as aviation, furniture, automobiles, instruments, machinery, and decoration. riveted on. The main reason why it is difficult to distinguish it from a rivet nut is that the purpose of the two is so similar that it is easy to confuse the two. But, the two are not the same. Welding nuts of thin metal plates and thin tubes are easy to melt, and the shortcomings of tapping internal threads are easy to slip, which are the most likely problems when riveting. At this time, rivet nuts come in handy. The riveting is firm, efficient and easy to use.

Let's take a look at the pressure riveting nut. The function of the pressure riveting nut is similar to that of the riveting nut. It is a nut applied to a thin plate or sheet metal. . Generally speaking, the hole diameter of the preset hole is slightly smaller than the embossed teeth of the riveting nut. The embossed teeth of the riveting nut are squeezed into the plate by pressure, causing the periphery of the hole to be plastically deformed, and the deformed object is squeezed into the guide groove, thereby produces a locking effect.

In terms of appearance, the difference between the rivet nut and the pressure rivet nut is still very big, but their main functions are almost the same. They all provide threads for thin plates, but the way of installation is different. The method of installation greatly determines the purpose and use of a nut.<

First of all, the installation method of the rivet nut is to use a riveting gun to perform riveting, so it is suitable for use in places where it is not easy to press riveting such as square tubes and round tubes. The rivet nut also makes up for some of the shortcomings of electric welding, such as aesthetics, and places that are not easy to weld, such as thin plates. Rivet nuts are mostly used in some chassis cabinets, square tubes and round tubes, fan production, equipment production, and zinc steel guardrails.

Let's take a look at the installation of the pressure riveting nut. The pressure riveting nut is also used on the top of the chassis cabinet sheet to provide threads. Its operation method is to use a pressure riveting machine for pressure riveting. In this case, the requirements will be higher, and a riveting machine is required. After the pressure riveting nut is riveted to the upper side of the sheet, it is very flat and will not have protrusions. Pressure riveting nuts are mainly used in the production of some chassis and cabinets, as well as some equipment production, water pumps, automobiles, and other production enterprises.

The installation of the pressure riveting nut is exquisite. If the installation method is not correct, the riveting will not be firm after the pressure riveting. To install the rivet nut, you must use special installation equipment, or simply install it with a press and stamping equipment (generally factories will have these simple equipment).

Briefly talk about the most intuitive difference between rivet nuts and rivet nuts: the most important point is that rivet nuts can be used on the top of finished and semi-finished products, while rivet nuts must be used on thin plates, and the finished products are used for No pressure riveting nut, because it is not suitable for the operation of the riveting machine. This is the main reason for the different division of labor between the two.
