The structure and stamping process of metal cover for ceiling lamp were analyzed. Firstly, the forming part of metal cover for ceiling lamp produced by progressive mold was designed, and the strip diagram of the progressive mold was introduced in detail. Then, the tearing process mold in the progressive mold was analyzed, and two grooves were designed on the die of tearing process mold to prevent the complete disconnection between process material and strip material. Secondly, the bending mold was designed to bend the material at the mouth of semi-product produced by the progressive mold. In the lower mold of the bending mold, four sliders and four inclined roofs were designed, that is, the material at the mouth of product was bent inward by the sliders, and then the product after bending was ejected from the positioning core of lower mold by inclined roof. Finally, two sets of crimping molds were designed. The first set was pre-crimping mold, which was used for preliminary crimping of products after bending, and the second set was forming crimping mold. However, in the metal cover mold of ceiling lamp, the bending process mold was the key mold.
