Description

[0002] The entire transformer requires multiple insulating sleepers, which need to be cut according to the shape of the transformer core. The current cutting is mainly carried out by cutting on the wooden board with a rotating milling cutter. Since the bottom of the wood is placed on the platform, the milling cutter cannot touch the platform. The problem with the cut sleepers is that the sleepers are not completely disconnected from the wooden board and need to be cut again. When the sleepers are disconnected from the wooden board, there are burrs at the fracture at the bottom of the sleepers. The fracture of the sleepers still needs to be polished to remove the burrs and rough parts. Secondary processing is required after cutting, which increases labor costs and reduces production efficiency. Summary of the Invention
