Features of pressure riveting screw connection

2021-05-06

The pressure riveting screw connection forming technology is a physical connection technology that uses the principle of stamping and riveting to form connecting dots between plastically deformed plates (such as metal plates) through die technology. The connection dots formed by extrusion hardly damage the intrinsic characteristics of the material, and have excellent dynamic connection fatigue strength; easy to realize automatic and large-scale production; easy to control product quality; low labor intensity; environmental protection and pollution-free characteristics .

The core of the riveting screw connection forming technology is to extrude suitable dots on the sheet to connect the upper and lower sheets together. The process of connecting the forming dots with pressure riveting screws can be divided into four stages: initial press-in, initial forming, plastic forming and holding pressure

Features of pressure riveting screw connection

① The pressure riveting screw connection has almost no damage to the intrinsic characteristics of the material, and there is neither high temperature nor chemical change in the entire dot forming process. Therefore, regardless of whether the material has plating, interlayer or covering, it can make the material original No damage to performance;

②The application range of the pressure riveting screw connection is very wide. In theory, as long as the metal plate that can be plastically deformed can be connected by the pressure riveting screw;

③The pressure riveting screw link is easy to realize automatic and large-scale production;

④Easy to carry out product quality control;

⑤It has the characteristics of low labor intensity, environmental protection and no pollution;

⑥Compared with spot welding of the same thickness, the connection strength of pressure riveting dots is about 70% of that of spot welding;

⑦Compared with spot welding, the pressure riveting screw connection can save 30%-60% of the cost;

⑧ Pressure riveting screw link can increase the strength by increasing the number of dots, and the distance between the dots can be made very close.
