Abstract: [Objective] On the premise of meeting production requirements, design a simple and efficient stamping mold for producing triangular agricultural sheet metal parts or similar shaped sheet metal parts. [Method] The author studied the structural characteristics of triangular agricultural sheet metal parts, and developed a suitable layout plan based on the requirements and characteristics of the sheet metal parts. The overall forming process plan was determined to be: blanking→forming→punching, that is, the forming of the sheet metal part requires a total of three sets of molds. The focus was on analyzing the forming process of the sheet metal part and the structural design and related calculations of the composite mold for the forming process. [Result] The structural design of the forming die is reasonable, and it can reliably complete actions such as feeding, positioning, stamping, and ejecting parts, with high production efficiency, low cost, and fully meeting design requirements. [Conclusion] The triangular agricultural sheet metal forming process is a relatively successful mold design, which can provide reference for the production of similar agricultural sheet metal parts.
