The knowledge about heat riveting of riveting machine

The heat riveting of the riveting machine is made by changing the temperature of the two metal parts and melting them together.

Rivet after heating to a certain temperature. Because of the plastic rivet after heating increased, the hardness decreased, the nail head is easily formed, so the force required for hot riveting the pressure is much smaller. In addition, during the cooling of the rivet, the contraction of the length of the nail bar will increase the positive pressure between the plates. When the sheet metal is loaded, it will produce greater friction resistance and increase the riveting strength. Hot riveting is often used in the case that the rivet material is poor in plasticity, rivet diameter is large or rivet force is insufficient.

When the rivet is hot riveted, the heating temperature of the rivet is different from the rivet material and the riveting method. For the steel rivet, when the rivet gun is riveted, the heating temperature is 1000-1100 DEG C. When riveting with riveting, the heating temperature is 650 - 670. The final riveting temperature of rivets is between 450-600 degrees centigrade. In hot riveting, the pressure of compressed air should be no less than 0.5Mpa in order to guarantee the quality of riveting. Riveting should also pay attention to the order of each rivet, it is necessary to carry out the key, symmetrical position of riveting, so that the force of the plate evenly.
