Description

Technical Field

[0001] The utility model relates to a carbon electrode processing device, in particular to a carbon electrode double-end tapered material removal device. Background Art

[0002] Carbon electrodes are used in the electrolysis of various alkali and alkaline earth metals; in the electrolysis of aluminum and magnesium, and in dry cell batteries. Specialty carbon electrodes include porous carbon electrodes based on carbon fibers, used in fuel cells, and glassy carbon electrodes (GCEs), made by carbonizing thermosetting resins. These electrodes are highly pure and chemically resistant and are used for analysis. Carbon electrodes are widely used in the metallurgical, chemical, and electrochemical industries. In practice, carbon electrodes are typically connected end-to-end using threaded connections, with the external threads on one end of one carbon electrode threaded onto the internal threads on the other. Currently, the applicant uses the machine tool described in prior patent application 201711171312.9 to create the external and internal threads on carbon electrodes. This process involves turning and boring to create the external cone and internal taper. This process is labor-intensive and time-consuming, and the carbon material is wasted after cutting and cannot be recycled or reused, resulting in high production and processing costs.
