Embodiment 1

[0015] This embodiment is a CNC graphite electrode double thread comb processing machine tool, its basic structure is as follows figure 1 and figure 2 shown. The two ends of the guide rails on the upper surface of the bed 9 are respectively equipped with spindle boxes 3, and the bottom backing plates of the two spindle boxes 3 are connected with the screw rods driven by the longitudinal feed motor 1 at both ends of the bed 9 to form a longitudinal feed mechanism. Driven by 1, the headstock 3 can move horizontally along the guide rails of the bed 9, and the guide rails are covered with a telescopic dust cover 5 in order to prevent the graphite chips from polluting the bed. The main motors 2 on the two spindle boxes 3 are connected with the main shaft through the gear transmission mechanism in the spindle boxes 3 . The outer surface of the front end of the main shaft is fixedly installed with a dust collection cover 15 connected to the dust collection device, so the dust gene...

Description

technical field [0001] The invention relates to a thread processing machine tool, in particular to a graphite electrode thread processing machine tool, which belongs to the technical field of mechanical processing equipment. Background technique [0002] Graphite electrodes are important purchases in the metal smelting industry. Because the graphite electrode material is soft, bulky and requires high processing precision, the processing equipment is special. In particular, the inner taper thread processing of graphite electrodes requires the superimposition of helical motion and cutting motion, and the processing quality of the workpiece not only directly affects the bonding strength of the electrode when it is used, but also has a crucial impact on the electrical conductivity of the electrode. Therefore, it is the most complex and critical process in graphite electrode processing. [0003] At present, only a few countries such as the United States and Japan can manufactur...
