1. Stamping die riveting: the traditional riveting technology which was popular earlier and scientific research earlier. The riveting force is released by manual hammering and equipment stamping die to the radial direction. Defect: if the riveting force required for riveting is large, the bolt with large diameter cannot be riveted. The riveting quality of impact riveting is not high, the noise is high and the office environment is weak. 2. Rolling and riveting: during the whole process of rolling and riveting, the riveting die seat (riveting rod) and the bolt center line are in sharp intersection angle. When doing special track, it is also a fitness exercise with directed diastolic pressure, which makes the top of the bolt head suffer from continuous partial symmetrical rolling effect and produce the required double drum rivet manufacturer's riveting appearance. It can be divided into axial type and swing roller type. Relative traditional bolt riveting, rolling riveting in the whole process of riveting, no relative sliding, no impact, high riveting quality, low energy consumption (low riveting strength, high efficiency), low noise and vibration, can rivet a variety of raw materials. Easy to use and wide coverage, it can be used for riveting with bolts or without bolts. It can be used for many difficult riveting raw materials and unique connector appearance. If according to the need of riveting iron rivets, change the appearance of the riveting die base.
