Users need to know several riveting machine riveting methods

1. The pendulum force required by cold rolling riveting method is very small, only 1/10-1/15 of that of hammer and stamping riveting method. Because the traditional riveting method is the rivet rod pressure on the rivet in advance, the pressure closer to the axis, the greater the cold roll riveting method is based on continuous local deformation of the rivet forming, the greater the pressure applied from the center of the rivet, which precisely conforms to the natural law of material deformation. Therefore, the cold roll riveting method requires very little equipment tonnage and saves costs.

2, cold rolling riveting method to make the deformation of the rivet follow the natural flow of metal, will not reduce the material gap impact toughness and ductility, reduce the risk of tangential tensile stress around the head of the rivet pier, riveting material without broken fiber flow, can improve the bearing capacity of the rivet. The destructive tests of swing cold roll riveting and traditional hammer and stamping riveting specimens show that the joint strength produced by cold roll riveting is about 80% higher than that of traditional riveting. After cold roll riveting, there are almost no deformation phenomena such as bending, bulging belly and thick pier. At the same time, the parts connected to the rivets are not deformed. And with hammer, stamping riveting, due to case pressure, impact in full bloom, the above defects are more obvious.

3, cold roll riveting method riveting head on the rivet for pure rolling without sliding, rivet forming surface roughness only depends on the rivet head, and the surface roughness of the rivet head is easy to ensure, so the cold roll riveting rivet surface smooth appearance is incomparable to other riveting methods.

4, using cold roll riveting method riveting almost no noise (less than 70dB), no vibration. And the traditional hammer, stamping riveting way noise more than 90dB.

5, the operation of cold rolling riveting machine is convenient and safe. Press riveting often happen to wash out fingers and other malignant accidents, manual hammer riveting accidental injury also happen, but crush riveting is relatively safe. Although the spindle has rotation, but there is a feasible safety cover, riveting head and workpiece contact surface is small.

6. When using cold rolling riveting machine, due to the special deformation performance of rivet material, the rivet rod will not have quality problems and has a high life. At the same time, as long as the shape of the rivet head is changed, various shapes can be riveted.
