"变压器储油柜端盖模具设计及工艺分析"

Abstract The structure and processing property of bellows oil conservator end cover for transformers were analyzed. The blank dimensions and pressing force were calculated, with the aim of improving the production efficiency of the end cover. A combined die for blanking, deep drawing, and punching was designed to achieve this goal. Through process analysis and structural design, the feasibility of the combined die was demonstrated, ensuring the quality of the product. In the mold design process, existing knowledge and resources were fully utilized to improve speed and efficiency. Pro/E surface design function was used to quickly calculate the surface area. The stamping die design software was employed to rapidly design the stamping die, with the die strength being inspected. The practice proved that the design speed and efficiency were indeed improved. In this mold design, due to the large stripping force, the advantage of using a combination of large spring force was used to solve this problem. In the mold structure, the punch plate was used as the locating element of the convex mold. However, the small distance between the locating elements could easily cause the convex mold to break. Therefore, a concave mold guiding the convex mold was designed to enhance the strength of the convex mold.
