1results about How to "Reasonable weight" patented technology

The utility model belongs to the technical field of forging and pressing processing, and particularly relates to an oxygen lance nozzle forging and pressing die which comprises a lower die fixing frame, the lower die fixing frame is connected with an upper die fixing plate in a sliding mode through a positioning assembly, an upper die is fixedly connected below the upper die fixing plate, a lower die assembly is fixedly connected above the lower die fixing frame, and the lower die assembly comprises a lower die fixing base. The lower die fixing base is fixedly connected with the lower die fixing frame, a lower die block is fixedly connected into the lower die fixing base, a center block is arranged in the center of the lower die block, a plurality of oxygen column blocks are arranged between the lower die block and the center block, and the center block can move up and down to drive the oxygen column blocks to be away from or close to the lower die block. The oxygen lance nozzle demoulding device has the advantages that the conception is ingenious, the structure is reasonable, the oxygen lance nozzle which is light in weight, cannot cause overweight of products and does not need to be subjected to subsequent processing to remove redundant materials can be produced, and the demoulding problem of the oxygen lance nozzle is ingeniously solved.
