Pressure riveting screw It is a kind of very commonly used fastener, it is mainly the stud which is turned by the lathe in the riveting stud industry. The general riveting screw is mainly made of stainless steel, carbon steel, copper and other materials. Into the. Because it has been heat treated and galvanized after production, it has good corrosion resistance.
For the use of screws, we generally do not pay much attention to the screws, because the screws are also less so, it is difficult to receive our attention, but this does not mean that the screws are not important, many machines or products, often less one screw can Lead to product retirement. It is still relatively common in our life, and there are many kinds of it, so today Jiuzheng Hardware Network will introduce the use and production technology of riveting screws and take a look.
The riveting screw is used in the use of a small hole in the base body, the riveting screw into the hole, the use of riveting equipment parallel and evenly pressed at the head, due to the riveting screw head under the teeth Embossing, when pressed in, causes the base body to deform around the clinching screw and bite the teeth, creating a firm external thread.

The advantages of riveting screws
1, easy to install, just simple riveting;
2, high torque resistance;
3, surface processing without danger, suitable for coating materials;
4, specifications series, to meet a variety of design requirements;
Use of riveting screws
The initial production and use of pressure riveting screws originated from the United States PEM/TEXRON and other companies, especially the use of the telecommunications industry, sheet metal industry and other products. With the extensive use of pressure riveting screws, we need to know that in the process of using the riveting screw, a small hole is made in the base of the riveting screw, and then the pressure riveting screw is accurately put into the punched hole. , Be careful not to install it. Afterwards, the pressure riveting screw equipment shall be pressed horizontally and evenly on the head of the pressure riveting screw. When the pressure riveting screw presses in, the base of the pressure riveting screw will be deformed around the machine, thus playing a fixed effect. .

Pressure riveting screw production process
1. First, the material that needs to be used for the production of the riveting screws, such as what metal or other material.
2, after the need to determine the pressure riveting screw specifications, type, size, length and other characteristics, in order to be able to produce.
3. After determining the material, size, specifications, and properties of the riveting screw, you can try to make a common riveting screw at this time. Under normal circumstances, there will be corresponding molds in many factories because of the production of screws. Implementation will have a model. If not, then additional ordering of the riveting screw model is required.
4. After the pressure riveting screw production process is ready above, at this time, we must use the pressure riveting machine pier to punch out the shape of the pressure riveting screw we need. This is mainly to create the appearance of the pressure riveting screw we need.
5. After the pressure is applied, the machine can be pierced, and then the tapping screw is used to perform tapping on the riveting screw.
6. After the thread of the riveting screw to be pressed is attacked, the electroplating process is performed lastly. Note that the electroplating can be performed according to the color of the electroplating.
