The utility model belongs to the technical field of storage battery grid
processing and manufacturing, and particularly relates to a device for preparing a perforated
lead plate of a lead-acid battery, which comprises a
punching machine and a feeding roller, the
punching machine comprises a
fixed frame, and an upper die mechanism, a lower die mechanism and a positioning component which are arranged in the
fixed frame, the upper die mechanism and the lower die mechanism are symmetrically arranged on the upper side and the lower side of the positioning
assembly, each of the upper die mechanism and the lower die mechanism comprises a die, a pushing piece, four positioning sliding rods and a spring, a plurality of
stamping heads are arranged on a vertical die on the lower side face of the die of the upper die mechanism, butt joints are arranged on a vertical die on the upper side face of the die of the lower die mechanism, and the
stamping heads correspond to the butt joints. The device ensures that the
stamping position is accurate, the
lead plate is prevented from shaking or tilting, the problems of stamping deformation, material shortage and the like are reduced, displacement or deformation of a material belt is prevented, breakage or incomplete stamping caused by uneven local stress is avoided, and the stamping quality is improved.
