4. There is no noise (less than 70dB) and no vibration when cold rolling riveting method is used. However, the noise of traditional hammering and stamping die riveting method is more than 90 dB. 5. The cold rolling riveting machine is easy to operate and safe. The high-speed punch riveting often leads to serious accidents such as washing away fingers, and injuries caused by human hammer riveting often occur, and the relative safety of rolling riveting is relatively safe. Although the main shaft bearing of waterproof lantern core pulling rivet has rotation, it has feasible safety protection cover, and the rivet head and the surface of product workpiece are small. 6. When the cold rolling riveting machine is used, because the bolt raw material has special good deformation characteristics, the riveting rod is not easy to have product quality problems and has a long service life. In addition, if the appearance of the rivet head is changed, a variety of forms can be riveted. 1. Rivetable raw materials: in addition to riveting high carbon steel bolts, but also riveting low carbon steel and stainless steel rivets, automotive rivets wholesale natural copper, aluminum bolts are also in the category of riveting. 2. Rivetable appearance: if you change the appearance of the rivet head, you can rivet into various shapes. In addition, the axial riveting machine can also be used for stamping.
