The invention discloses a reinforced structure of a combined transformer tank door, and a manufacturing method of the reinforced structure. The manufacturing method comprises the steps that: firstly, a steel plate material for the combined transformer tank door is placed on a common flanging machine after being blanked; secondly, the inwardly convex depths of convex ribs are confirmed according to the size and the thickness of a tank door steel plate; the stamping lengths and the stamping widths of the convex ribs are adjusted according to the size of the combined transformer tank door; stamping positions and stamping patterns of the convex ribs are confirmed according to a requirement of the combined transformer tank door on the strength; thirdly, the strip-shaped convex ribs with convex surfaces facing towards the inner side of the tank door are stamped on the steel plate by a stamping force of a flanging machine mold; and fourthly, a technological requirement of stamping operation of the convex ribs is the
