Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metallurgical devices, in particular to an electrode tightening device. Background Art
[0002] In the industrial processes of iron and steel metallurgy, electrolysis, smelting, electroplating, etc., electrodes are key conductive consumable materials, and their length will gradually be consumed as the production process continues. In order to ensure the continuity and efficiency of the production process, it is necessary to regularly lengthen the shortened electrodes. However, in the process of electrode lengthening, due to the gravity of the electrode itself, improper operation or external factors (such as vibration, wind, etc.), the electrodes often tilt, shake or even slip. This not only affects the quality and efficiency of electrode lengthening, but may also pose a threat to equipment and personnel safety.
[0003] Traditional electrode splicing devices usually only focus on the clamping and splicing functions of the electrode, but ignore the balance and stability of the electrode during the splicing process. Therefore, during the splicing process, operators often need to spend a lot of time and energy to adjust the position of the electrode to ensure that it remains balanced and stable during the splicing process. This not only increases the labor intensity of the operators, but also reduces the efficiency and quality of the electrode splicing.
[0004] However, most of the existing devices have poor fixing effects, and sometimes the graphite electrode may fall off the device. In particular, many existing tightening devices used in the electrode extension process are often not sure whether their components have tightened and fixed the electrode in place during operation due to design problems. If the device is not tightened and fixed in place, the operation will continue, and the electrode will fall off the device, which will inevitably cause damage to the electrode and seriously affect the efficiency of the electrode extension process.

Compared with the existing electrode fixing device, the limit blocks 50 of the device are multiple, and no less than five are provided in the specific assembly, which can abut against various angles of the side surface of the electrode, so that the fixing and limiting effect of the electrode is better, and the electrode is not easy to fall off from the device.
[0018] When implementing it, Figure 1 As shown, the first fixing mechanism 30 includes a first fixing plate 31, a first oil cylinder 32, a first connecting plate 33, a second fixing plate 34 and a first clamping block 35; the first fixing plate 31 is arranged on the outer side of the inner sleeve 20; the first end of the first oil cylinder 32 is rotatably connected to the first fixing plate 31; a first rotating shaft opening 331 is opened on the first connecting plate 33, and the first end of the first connecting plate 33 is rotatably connected to the second end of the first oil cylinder 32; the second fixing plate 34 is arranged on the outer side of the inner sleeve 20; the first connecting plate 33 is rotatably connected to the second fixing plate 34 through the first rotating shaft opening 331; the first clamping block 35 is rotatably arranged at the second end of the first connecting plate 33; wherein the first oil cylinder 32 is used to push the first connecting plate 33 so that the first clamping block 35 moves toward the inner side of the inner sleeve 20 and pushes one side of the electrode through a fixing hole 21, and the pressure generated by the first oil cylinder 32 is used to push the electrode so that the entire first fixing mechanism 30 generates an inward rotation pushing stroke, which can ensure that one side of the electrode can be clamped.
[0019] When implementing it, Figure 1As shown, the second fixing mechanism 40 includes a third fixing plate 41, a second oil cylinder 42, a second connecting plate 43, a fourth fixing plate 44 and a second clamping block 45; the third fixing plate 41 is arranged outside the inner sleeve 20; the first end of the second oil cylinder 42 is rotatably connected to the third fixing plate 41; a second rotating shaft opening 431 is opened on the second connecting plate 43, and the first end of the second connecting plate 43 is rotatably connected to the second end of the second oil cylinder 42; the fourth fixing plate 44 is arranged outside the inner sleeve 20; the second connecting plate 43 is rotatably connected to the second end of the second oil cylinder 42 through the second rotating shaft opening 431 The second clamping block 45 is rotatably arranged at the second end of the second connecting plate 43; wherein the second oil cylinder 42 is used to push the second connecting plate 43 so that the second clamping block 45 moves toward the inner side of the inner sleeve 20 and passes through a fixing hole 21 to push one side of the electrode.
