[0002] Wire cutting machine is a device that cuts the material to be cut (such as silicon rods, semiconductors, silicon carbide, sapphire, magnetic materials, stone and other materials) by the high-speed reciprocating motion of the cutting wire. That is, the material to be cut is sent into the roller bracket wrapped with the cutting wire through the lifting mechanism, or the material does not move, and the roller bracket is lowered and raised by the lifting mechanism to cut the material. At present, the connection method between the roller bracket and the lifting mechanism of large-scale wire cutting machine is that a connecting seat is provided in the middle part of both sides of the roller bracket, and the connecting seat is connected to the middle position of the lifting mechanism.
