The invention discloses a hot-forming line discharging table double-centering system. The double-centering system comprises a plurality of first centering fingers and a plurality of second centering fingers, the first centering fingers and the second centering fingers are correspondingly arranged in rows on the left side and the right side of a furnace roller frame, the double-centering system further comprises at least one third centering finger and at least one fourth centering finger arranged between the first centering fingers and the second centering fingers, the third centering finger and the fourth centering finger are correspondingly arranged at the positions, near the left and the right, of the middle part of the furnace roller frame, the first, second, third and fourth centeringfingers are correspondingly arranged between transmission rollers, and the first, second, third and fourth centering fingers move left and right under the action of corresponding driving air cylinders. According to the hot-forming line discharging table double-centering system, the structure is simple, operation is convenient and fast, fast positioning of multiple material sheets can be simultaneously achieved, and the problem that multi-cavity short material sheets can not be simultaneously produced is solved; for material sheet products with complex shapes, more choices of the centering fingers are provided during debugging; the centering fingers are driven by adopting the air cylinder, positions can be adjusted manually after closing air source, and debugging is convenient.
