The invention discloses a self-suction-chip stamping device for machining a steel sleeve bearing. The self-suction-chip stamping device structurally comprises a stamping platform body, a stamping motor head, a hydraulic rod set, a bearing box, a bottom cushion base and a control box; when the device is used, a magnetic attraction block mechanism is arranged, so that the lower bearing table can beprevented from being required to have extremely high bearing capacity, meanwhile, when punching is carried out, a certain amount of chips can be generated by the high pressure, the chips can stay at the periphery of the lower module, the die is a more accurate structural component, so that the metal chippings need to be cleaned frequently otherwise the accuracy of the mechanism can be influenced,the problem that irreversible influence is brought to the mechanism, the device can be used for carrying out automatic matching and adsorption on metal chippings generated on the bearing table, so that the flatness accuracy of stamping is guaranteed.
