The application discloses an aluminum cover forming method and an aluminum cover and relates to the technical field of aluminum cover manufacturing. The aluminum cover forming method comprises the following steps: S1, placing an aluminum plate into an initial forming die, and forming a macro-domain large curved surface in the middle of the aluminum plate and an initial foot position with the same height as a required foot position on the circumferential edge of the aluminum plate through the extrusion force of a press machine and the initial forming die; S2, placing the aluminum plate preliminarily formed in S1 into a final forming die, and further forming the macro-domain large curved surface formed in the middle of the aluminum plate into a final shape at room temperature through the final forming extrusion pressure of the press machine, and flowing and filling the edge cavity of the final forming die to form an edge through the extrusion of the final forming die, and forming a final foot position shape through the extrusion of the initial foot position; and S3, opening the die to take out the formed aluminum cover. The production of the large-size foot position height aluminum cover can be realized at room temperature, the energy consumption is low, and the aluminum cover is simple and convenient to manufacture.

The utility model provides a lamp packaging box which comprises a box body and three sealing panels, the three sealing panels are arranged on three adjacent edges of the top of the box body and integrally formed with the box body, and the three sealing panels are folded and sealed relative to an opening in the top of the box body. The limiting protection plate is arranged on the free edge of the top of the box body and extends outwards, the limiting protection plate comprises a first fixing section, a second fixing section and an elastic limiting section connected between the first fixing section and the second fixing section, and one side of the first fixing section and the free edge of the top of the box body are integrally formed; after the limiting protection plate is folded into the box body, the first fixing section is attached and limited to the inner wall of the side, connected with the first fixing section, of the box body, the second fixing section is attached and limited to the inner wall of the opposite side, connected with the first fixing section, of the side, connected with the first fixing section, of the box body, and the elastic limiting section stretches across the surface of a lamp to be packaged. And the lamp to be packaged abuts against the inner wall of the bottom of the box body.
