Description

Technical Field

[0001] The invention relates to the technical field of graphite square electrode processing, in particular to a graphite square electrode processing device. Background Art

[0002] In resistance furnaces such as graphitization furnaces and glass melting furnaces, graphite square electrodes are embedded in the furnace head wall as conductive materials. Their square structure can optimize the internal space layout of the equipment and improve thermal efficiency. They are suitable for scenes such as silicon carbide production, vitrification and high-temperature processing of graphite products. As a high-temperature conductive material, the manufacture of graphite electrodes requires multiple processes such as calcination, molding, and graphitization. During the mechanical processing stage, drilling is one of the key processes. The existing processing method uses a special fixture to fix the electrode on the machine tool and uses a drill bit to precisely drill its end. This process relies on manual clamping and positioning, and the electrode fixing, drilling, and disassembly processes must be completed one by one.

[0003] The current processing method has an obvious efficiency bottleneck: after completing the drilling of each electrode, the fixture must be removed and the next electrode must be re-clamped, resulting in interruptions in the processing process. This intermittent operation mode not only prolongs the production cycle, but also increases the labor intensity of the operator. In addition, frequent clamping operations are prone to introduce positioning errors, affecting the consistency of drilling accuracy. For this reason, we propose a graphite square electrode processing device. Summary of the invention
