Die for manufacturing angle ring for transformer

The utility model discloses a die for manufacturing an angle ring for a transformer. The die comprises a frame. The frame comprises a top plate and a bottom plate. The bottom plate is provided with two square columns perpendicular to the bottom plate, one side of each square column is provided with a plurality of pressing dies used for carrying wet raw paper and stacked together, a leaf spring is arranged on the tops of the pressing dies, and a pressing device penetrating through the top plate and acting on the leaf spring is arranged on the top of the leaf spring. According to the die for manufacturing the angle ring for the transformer, the leaf spring is arranged, force can be continuously exerted on the leaf spring through the pressing device, the pressing dies can be evenly stressed through the leaf spring, and the quality of the angle ring is ensured. After the raw paper is added to and put on the die, an independent steam supplying system is not needed for drying, and the die can be dried in a drying room with other special-shaped parts. In addition, 100 angle rings can be machined at a time, the overall production efficiency is greatly improved compared with the production efficiency of a traditional technology, and the problems of difficult operation, high cost and the low yield in the prior art are solved.
