For example, it involves the assembly and connection process of metal sheets in automobile sheet metal repair: if only some simple riveting methods are used, the metal plates cannot be well combined to produce riveting effect, or the effect is not obvious, and it will fail in severe cases. It will directly affect its overall performance, and further cause immeasurable harm to the safety performance of the car; if the traditional welding process is used, the operation process is relatively complicated, and the process of repairing some small metal sheet parts is not flexible enough, and welding The process requires a large current, which is not conducive to resource conservation to a certain extent

The invention discloses a portable metal plate riveting device. The portable metal plate riveting device comprises a hydraulic pump, a pipeline assembly, a hydraulic driver, a rivet clamp and a control switch. A first air pipe is connected with a high-pressure air source and an air inlet of the control switch. One end of a second air pipe is connected with an air outlet of the control switch, and the other end of the second air pipe is connected with an air inlet of the hydraulic pump. The control switch is used for controlling the on-off state of the first air pipe and the second air pipe. One end of a hydraulic pipe is connected with an oil return hole of the hydraulic pump, and the other end of the hydraulic pipe is connected with a hydraulic pipe connector of the hydraulic driver. The hydraulic driver comprises a driving shell, a piston head, a piston rod, a piston return spring and the hydraulic pipe connector, wherein the hydraulic pipe connector communicates with a cavity of the driving shell, one end of the piston rod stretches out of the driving shell, and the piston head is movably installed in the cavity of the driving shell. The rivet clamp is connected and matched with the hydraulic driver. The portable metal plate riveting device is simple in structure, low in weight, capable of generating high riveting pressure and adaptable to sheet metal connection during automotive metal plate repairing.
