The invention discloses an iron ring pressing and disengaging machine. The iron ring pressing and disengaging machine is used for pressing and disengaging an iron ring obtained after anode electrolysis. The iron ring pressing and disengaging machine comprises a machine base, an iron distribution device, a push rod and a flexible sealing part. A vertically-through guide channel is limited in the machine base. A clamping arm for clamping an anode is arranged above the machine base. The iron distribution device is provided with a stamping channel communicated with the guide channel. The push rod is movably arranged in the guide channel and the stamping channel in the axial direction of the guide channel and in the axial direction of the stamping channel. The upper end of the push rod is provided with a punch. The flexible sealing part is arranged on the iron distribution device to cover the upper surface of the iron distribution device and provided with a through hole allowing the push rod to penetrate. The push rod penetrates the through hole and the peripheral wall of the push rod is tightly attached to the flexible sealing part. According to the iron ring pressing and disengaging machine, the flexible sealing part is arranged on the iron distribution device and tightly attached to the peripheral wall of the push rod, the sealing function can be achieved, and it is avoided that impacting iron scraps from anodes fall into the stamping channel and the guide channel.
