The invention discloses a stamping shaping device for resistor aluminum shell machining, and relates to the technical field of stamping machining equipment.The stamping shaping device comprises a base table, a die groove is formed in the middle of the base table, a lower die table is fixedly installed in the middle of the inner wall of the die groove, the lower die table is arranged in an upward protruding mode, and an oil inlet hole used for guiding stamping oil in is formed in the top of the lower die table; a jacking and discharging mechanism used for jacking out the stamped aluminum shell is arranged below the lower die table. The jacking discharging mechanism is arranged below the lower die table, discharging of the aluminum shell is achieved in a jacking mode in an auxiliary mode, due to the particularity of the resistor aluminum shell structure, negative pressure is generated between the aluminum shell and the lower die table and between the aluminum shell and the upper die table in the lifting and separating process, the upper oil conveying pipe and the lower oil conveying pipe are arranged in the upper die table and the lower die table correspondingly, and the resistor aluminum shell can be discharged conveniently. Stamping oil is sucked out through negative pressure matched with discharging operation, the cooling and lubricating effects are achieved, and friction and abrasion between the aluminum shell and the die are reduced.
