1. The traditional hand craft of riveting pliers and pliers is hot riveting and punching riveting with electric heater. The hot riveting not only consumes a lot of energy (up to 20kW), but also the bolt is easy to peel and has low efficiency. Although punching riveting is efficient, it is easy to upset the middle of the bolt, and the tightness is not easy to ensure. Moreover, the noise is high and the actual operation is not safe. The cold rolling riveting just gets rid of the cover end. At present, more than 20 wire cutter factories in China have selected our cold rolling riveting machines, which further improve the quality and reduce the cost. 2. Riveting car door lock: car door bolts are not specified high, very tight loose provisions. Before the selection of manual riveting, labor efficiency, punch riveting and hand riveting are not easy to ensure the tightness, the appearance design is not good-looking. After cold rolling and riveting, it not only ensures the specified tightness, but also rivets various beautiful and elegant appearance designs such as small flat head, round string, inside and outside opposite sides. Easy to install on the automatic assembly line, a manufacturer successively equipped with more than 90 sets, assembled into four production lines, improved the quality and obtained very good economic benefits. 3. Turning from riveting car to ball joint and waterproof lantern rivet to ball joint is a component related to safety factor in car, so it should have sufficient compressive strength, bending stiffness, feasibility analysis, wear resistance and service life. The sealing of automobile stainless steel rivet ball cage is also the most important ring. Because of the selection of cold rolling riveting seal, high compressive strength, good airtightness and beautiful appearance design, this processing technology has been selected by more and more process engineers.
