A buffer protection device, a hot forging balancer, and a buffering method are disclosed, belonging to the technical field of hot forging presses. The buffer protection device includes a sleeve for mounting on top of the balancer. A lower piston rod is slidably disposed within the sleeve, with its lower end extending downwards out of the sleeve to contact the piston ejected from the balancer. An anti-loosening steel wire connects the sleeve and the lower piston rod. The tensioning and breakage of the anti-loosening steel wire dissipates some of the impact energy, achieving primary buffering. An upper piston rod is slidably disposed within the sleeve, coaxially arranged with the lower piston rod. A buffer bushing is fixed above the upper piston rod, guiding the upper piston rod to undergo plastic deformation, achieving secondary buffering. Through multi-stage buffering and energy absorption, the device smoothly blocks the ejected piston and piston rod after breakage, effectively preventing them from flying out while maximizing the absorption of impact energy and avoiding damage to the balancer cylinder.
