Description

Technical Field

[0001] The utility model relates to the technical field of graphite processing, in particular to a graphite blank cutting device. Background Art

[0002] Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties and corrosion resistance. It is not easy to react with acids, alkalis and other agents. Natural graphite comes from graphite deposits. It can also be made from petroleum coke, asphalt coke, etc. as raw materials and processed through a series of processes to make artificial graphite. The graphite three-piece set is used to fix the core rod in the polysilicon reduction furnace. The graphite three-piece set has a flap, a cap and a base. Among them, the graphite flap is first milled into a cone shape on a lathe, and then punched, and then divided into several blocks. Each divided graphite block is a graphite flap. The cutting of graphite blocks will produce a certain amount of debris and dust, which will pollute the working environment and pose a certain safety hazard to the operators. At the same time, the graphite blocks need to be limited and fixed when they are cut. The traditional clamping method is prone to certain wear problems on the outer surface of the graphite.
