The invention relates to a bending machine rack with a side protection function. The bending machine rack comprises two wall plates, the upper ends of the two wall plates are fixedly connected througha crossbeam, the lower ends of the two wall plates are connected through a connecting plate, mounting plates are arranged at the upper ends of the front sides of the two wall plates and provided withmounting holes, a baffle is arranged on the front sides of the lower ends of the two wall plates, the rear end face of the baffle is fixedly connected with the two wall plates, a worktable is fixedlymounted at the upper end of the baffle, a protective guard is arranged on the outer side of each wall plate, and the protective guards are connected with the outer side of the wall plate in a hingedmode. The bending machine rack is simple in structure and fast and convenient to mount, in the working process, operation is convenient, the transverse protective guard and the longitudinal protectiveguard are rotated when required, people can be prevented from colliding with the worktable from the side face, and working safety is improved; and the transverse baffle and the longitudinal baffle are additionally arranged, and thus interference in the worktable when the protective guards rotate is effectively prevented.
