The invention discloses a piece of automatic armature processing equipment for small electromagnetic relays, which includes a workbench and also includes a feeding mechanism, a bending mechanism, a groove-milling mechanism, a positioning transfer mechanism and a discharging mechanism. The positioning transfer mechanism includes a positioning track, a first positioning assembly and a second positioning assembly. The bending mechanism includes a bending transfer block and a bending drive assembly capable of driving the bending transfer block to go up and down. The bending transfer block is provided with a bending block for abutting against an armature. The groove-milling mechanism includes a milling cutter motor and a groove-milling moving assembly capable of drive the milling cutter motor to move obliquely. The feeding mechanism includes a feeding track. The discharging mechanism includes a discharging track and a taking assembly. The armatures of relays can be automatically bent and groove-milled only by feeding in sequence, and the production efficiency is improved.
