Description

Technical Field

[0001] This utility model relates to the field of graphite electrode processing equipment, and in particular to a high-efficiency cooling and cutting device for graphite electrodes. Background Technology

[0002] In modern industry, graphite electrodes are widely used in metallurgy, chemical industry, new energy industry, and other sectors due to their excellent electrical conductivity, high-temperature stability, and machinability. They play a crucial role as core conductive components, especially in electric arc furnace steelmaking and electrolytic refining processes. To meet the demands of different operating conditions, graphite electrodes require precise machining to achieve specific shapes, dimensions, and surface finishes. Therefore, cutting devices for graphite electrodes have become one of the core pieces of equipment for ensuring electrode quality. As industrial production demands increasingly higher performance from graphite electrodes, greater technical challenges are posed to the precision, efficiency, and equipment stability of their machining processes, driving continuous innovation and development in graphite electrode cutting devices.

[0003] Existing graphite electrode cutting devices typically employ a fixed frame as a support base, equipped with a spindle drive unit that rotates the cutting tool. A feed mechanism controls the movement of the electrode workpiece or tool along a specific trajectory, enabling machining operations such as turning, milling, or grinding of the graphite electrode. The technical principle is primarily based on the combination of mechanical transmission and CNC technology. A servo motor drives components such as ball screws and guide rails to achieve precise feed motion. Combined with the planned relative motion trajectory between the tool and workpiece, the electrode's shape is cut and shaped. Some devices also include simple cooling pipes, supplying coolant to the cutting area through nozzles at preset positions.

[0004] However, in the existing technology, the nozzle position of the cooling pipe is mostly fixed, which cannot be flexibly adjusted according to the different specifications of the graphite electrode, the cutting process and the processing position. This makes it difficult for the coolant to fully cover the cutting area of ​​the electrode, and it is easy to form a cooling blind zone on the electrode surface. Therefore, a high-efficiency cooling cutting device for graphite electrodes is proposed to solve the above problems. Utility Model Content

The tops of the multiple nozzles 10 are fixedly connected to the bottom of the connecting plate 8. Multiple fixing bolts 12 are threaded inside the connecting block 11. These fixing bolts 12 are used to firmly lock the adjusted connecting block 11, ensuring the stability of the cooling component during operation. An output device is fixedly connected to the top of the connecting plate 8. Pipe 7 extends through to the top of the cutting machine 1 at one end. A conveying assembly is provided at one end of the output pipe 7. This conveying assembly is used to provide a continuous supply of coolant to the cooling components. The conveying assembly includes a conveying pump 6, which is used to provide conveying power for the coolant and is the core component for achieving efficient cooling.

[0037] Reference Figures 4-6The absorption assembly includes a suction fan 25, which is located on one side of the movable support platform 5. The outer wall of the suction fan 25 is fixedly connected to one side of the cutting machine 1.

The two ends of the multiple limiting rods 23 are fixedly connected to the inner wall of the cutting machine 1. Multiple segmented tubes 20 are fixedly connected inside the connecting plate 19. Connecting hoses 21 are fixedly connected between the multiple segmented tubes 20. The connecting hoses 21 are used to connect the moving connecting plate 19 and the fixed filter box 24. Its flexible structure ensures the continuous connection of the dust collection channel during reciprocating motion.

[0038] Working principle: During the cooling process of the cutting part of the graphite electrode, the connecting block 11 is first pushed to slide up and down on the outer wall of the cutting tool 4 according to the processing requirements. This is to adjust the overall height of the connecting plate 8 and multiple nozzles 10 connected to the connecting block 11. After adjustment, multiple fixing bolts 12 are tightened to firmly lock the connecting block 11 onto the cutting tool 4. Then, the delivery pump 6 installed on the top of the cutting machine 1 is started. The delivery pump 6 draws in external coolant through the input pipe 9 and then pressurizes and delivers it to the connecting plate 8 through the output pipe 7. Finally, the coolant is evenly sprayed onto the processing surface of the graphite material through multiple nozzles 10 arranged in a ring array and tilted inward at the bottom of the connecting plate 8. This achieves all-round and efficient cooling of the cutting area, effectively solving the problems of insufficient cooling or dead corners in the previous cooling methods, which led to local overheating of the electrode and rapid wear of the tool. This enhances the cooling effect, thereby improving the processing accuracy and extending the service life of the equipment.

[0039] During the absorption of dust generated from cutting graphite electrodes, the suction fan 25 is activated. Utilizing its powerful suction, the diffused dust is rapidly drawn into the filter box 24 through multiple segmented pipes 20 and connecting hoses 21 on the connecting plate 19. The dust is effectively filtered and intercepted as it passes through the filter screen 26, protecting the suction fan 25 from damage. To achieve wide-area dust removal, the motor 15 is activated. The output of the motor 15 drives the chain drive assembly 13. The chain drive assembly 13, through the connecting bar 16 and the sliding plate 17, drives the connecting frame 18 and the connecting plate 19 fixed to one side. Guided by the slider 22 and the limiting rod 23, it performs reciprocating linear motion, achieving dynamic cleaning of the dust inlet. This expands the effective dust absorption range, successfully solving the problems of low dust collection efficiency and small coverage of fixed dust inlets, enhancing the collection and purification effect of dust on-site, and ensuring a clean working environment.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
