The Core-Shaping Press forms round laminated transformer cores into rectangular shaped cores of variable dimension. This is accomplished by compressing the cores with two independently controlled sets of opposing hydraulic cylinders. A secondary process tightens the internal corner radii by expanding the rectangular cores from within with an additional set of hydraulic cylinders. These cylinders were custom built by ETSM and feature anti-rotation.
Crane loading/unloading of cores is made easy with pivoting sections of the in/out conveyor feeds. This allows transformer cores to be oriented from vertical to horizontal positions. Also, table height in the forming zone can be adjusted allowing cylinder heads to be centered on mid-section of transformer cores. This increases quality of finished product.
