A riveting machine is a commonly used production equipment in the workshop of the automobile manufacturing industry, which can realize operations such as pressing parts into place, assembling, riveting, cutting, and bending. It mainly uses external pressure to change the plasticity of materials, presses riveting parts such as screws and nuts into special prefabricated grooves, so that reliable connection is achieved between parts. For the riveting of small batches of workpieces, it is generally completed by manually operating a small riveting device. At present, for small riveting devices, generally, a pull rod is used to drive the riveting head to quickly move downward to rivet the riveting position on the workpiece. However, the downward speed of the riveting head is difficult to control, resulting in inconsistent riveting pressures. Some workpieces are not riveted in place, while some are cracked due to excessive pressure, resulting in a high defective rate of riveting. Therefore, it is necessary to manufacture a manual riveting device to solve the above problems. Summary of the Utility Model
