Working principle of riveting press

Press riveting machine working principle: the machine's core components for the gas-hydraulic pressure cylinder, it is powered by the cylinder, through the cylinder force, so as to achieve the same as high-pressure pump pneumatic high-pressure effect of the moment. The action process is divided into three parts: up and down cylinder synchronizing, fast forward to the position of the die pressing wing, riveting process of the oil cylinder transient pressurizing stroke, fast aerodynamic retreat from any position or the starting position.　

In order to guarantee the quality of riveting, the riveting head should be cleaned regularly to prevent the metal from sticking and thickening. When cleaning, the riveting head is fixed on the chuck of the lathe, and then polished with sandpaper. Do not process more than the nominal capacity of the workpiece. Do not work for a long time in the high-pressure state, the length of the rivets should not exceed the specified value, encountered abnormal immediately stop maintenance, straight to the troubleshooting.

The Rivet Press is mainly assembled by rotation and pressure. It is mainly used for rivet (hollow rivet, hollow rivet, solid rivet, etc.) , single head and double head and other specifications. A method of riveting in which the static pressure produced by a riveting device roughens the riveting rod to form an upset head is called riveting. The riveting parts of press riveting have the characteristics of good surface quality, small deformation and high connection strength. Therefore, in the actual operation, as long as the structure technology allows, the preferred use of pressure riveting. Rivets can generally replace screws to connect, can let a number of parts connected together, the advantages are very obvious, strong case can make parts can rotate, usually through the riveting press to rivet to get good, although the device is small, there are a lot of things to be aware of when using it.    

Riveting machine structure: the equipment by the bed, pressure transmitter, pre-pressure upper and lower die gas-hydraulic pressure cylinder, pneumatic circuit, electrical control circuit. Using the Compressed air as the transmission power, the riveting function can be completed according to the production process requirements in accordance with the action of the main pneumatic components of the pneumatic control system and the mechanical, hydraulic, electrical, PLC controller, etc. .

Press riveting machine can be used in many aspects, especially the stamping machine equipment and special die after an instant high-pressure processing process, can achieve effective results, although the machine looks simple, in fact, its internal structure and the principle is more complex, which requires in-depth understanding.
