[0002] The pressure riveting machine (also known as the riveting machine, rotary riveting machine, riveting machine, rolling riveting machine, etc.) is a new type of riveting equipment developed based on the principle of cold rolling, which refers to mechanical equipment that can rivet objects together with rivets. It solves the problem that some sheet metal parts cannot be directly placed on ordinary slope cast steel machines for pressure riveting after bending.

[0003] In the prior art, metal lock plate nuts often need to be riveted by a riveting machine during the production process. Since the sizes of the metal lock plate nuts after production are different, and the riveting head on the riveting structure of the riveting machine is not replaced, the riveting machine can only process metal lock plate nuts of the same size, and metal lock plate nuts of different sizes cannot be processed on the same riveting machine. If metal lock plate nuts of different sizes need to be processed, it is necessary to purchase and replace the corresponding riveting machine, which not only increases the cost of using the equipment when processing the metal lock plate nuts, but also reduces the practicability of the riveting machine and the processing efficiency of the metal lock plate nuts.
