Since the HDS series is a disc spring that can be folded or overlapped. The combination of the butt joint can increase the deformation of the disc spring group, and the combination of the overlapping method can increase the spring force of the disc spring group. The ideal installation method is to flatten as much as possible. The closer it is to the flattened state, the faster the tension torque increases, and the proper bolt tension can be obtained without a torque wrench.

The development of a structure with simple production, reasonable structure and stable feeding is of great significance to the field of riveting automation. Technical realization elements: The purpose of this utility model is to overcome the deficiencies in the prior art, and to provide an automatic feeding device for pressure riveting nuts, which has a compact structure and a reasonable design, and can realize the automatic conveying of the pressure riveting nut on the pressure riveting die. Reduce the use of space, improve work efficiency and save labor costs. According to the technical scheme provided by the utility model: the automatic feeding device for riveting nuts, which is characterized in that: it includes an installation bracket, a connecting frame, a flap bracket, a material pushing cylinder, a material pushing block and a flap; the flap bracket is arranged on the installation Below the bracket and attached to the mounting bracket through the connecting bracket.


It can be seen that the above processing method can only be used to process a relatively simple retaining ring (that is, only a ring body, which cannot be cut or punched), and the outer surface of the processed retaining ring still cannot be guaranteed to be completely flat.
