Description

Technical Field

[0001] The invention relates to the technical field of metallurgy, and in particular to a cathode straightening device and a cathode straightening method. Background Art

[0002] Permanent cathodes are usually used as electrodes in the electrolytic refining of metals such as copper, zinc or nickel, and include conductive rods and mother plates. The cross-sectional area of ​​the conductive rod is much larger than that of the mother plate, which is welded to the conductive rod. The material of the mother plate is usually stainless steel or titanium, and the thickness of the mother plate is relatively thin, generally 3.25 mm. During the production operation, the permanent cathode is mechanically damaged due to hoisting operations, cathode copper stripping and transportation, causing the mother plate to bend and deform to varying degrees. Due to the requirements of the electrolytic pole distance, the bent and deformed permanent cathode is not only easy to contact with the anode plate and cause a short circuit, but also the quality of the cathode copper electrolyzed is poor, resulting in large energy loss and economic losses. In order to obtain qualified cathode copper and good electrolytic technical indicators, the deformed mother plate needs to be straightened before it can continue to be used.

[0003] With the widespread application of permanent cathode electrolysis technology in major smelters, the proportion of permanent cathodes that need to be repaired is increasing. At present, for mother plates with simple or small deformation, most of them are repaired manually; for mother plates with complex deformation (such as wavy or curved), it is necessary to first cut and separate the conductive rod from the mother plate to form a cathode plate with a single cross-section that can pass through the straightening equipment as a whole, and then re-weld the straightened cathode plate with the conductive rod. However, this separation or re-welding operation will reduce the conductive performance of the conductive rod and cause new deformation of the cathode plate to varying degrees, and even make the cathode plate scrapped.

[0004] In addition, patent CN 205701918 U discloses a nine-roller pinch straightening device, which is an expandable device, the rear end of the upper frame is movably connected to the rear end of the lower frame, and the upper pinch roller and the upper straightening roller can be controlled to move upward or downward by the extension and retraction of the upper frame support hydraulic cylinder to allow steel plates of different thicknesses to be fed from the feed inlet; the lower pinch roller and 4 sets of lower straightening rollers are fixed on the lower frame, and the upper pinch roller is connected to the upper pinch roller hydraulic cylinder. The distance between the upper pinch rollers can be adjusted according to the different strip models by controlling the distance between the upper pinch rollers; 3 sets of upper straightening rollers with a diameter of 190 mm are respectively connected to 3 sets of elevators, and the elevators are connected to the lifting hydraulic cylinders, that is, the amount of pressure and pressure can only be controlled by an independent hydraulic cylinder connected to a single working roller. This large roller diameter straightening device is generally suitable for straightening steel strips with larger plate thicknesses, but not for straightening thin plates. It has many structural parts and complex operations, and it is difficult to accurately control the amount of pressure and pressure.

[0005] In addition, the steel strip enters from the left end under the pinching action of the upper pinch roller and the lower pinch roller, and after being straightened by the upper straightening roller and the lower straightening roller, it is output from the right end driven by the conveying roller. In other words, when this straightening device is used, the steel strip can only enter from one end and then be output from the other end. When it is used for permanent cathode straightening, the permanent cathode must be separated and then welded. Summary of the invention

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The cathode straightening device 10 according to the first embodiment of the present invention is described below with reference to the accompanying drawings. The cathode straightening device 10 is suitable for straightening a cathode 20 , which includes a plate body 21 and a conductive rod 22 mounted at an end of the plate body 21 .

[0036] like Figure 1 and Figure 2 As shown, according to the cathode straightening device 10 of the embodiment of the present invention, the cathode straightening device 10 includes: a lower frame 100, an upper frame 200, an upper roller system 320, a lower roller system 310 and a driving assembly.

[0037] Specifically, the upper frame 200 is disposed above the lower frame 100, and the upper frame 200 and the lower frame 100 jointly define a working space 12 and a horizontal inlet and outlet 11, and the working space 12 is connected to the horizontal inlet and outlet 11. The upper roller system 320 is mounted on the upper frame 200, and the lower roller system 310 is mounted on the lower frame 100. The upper roller system 320 includes a plurality of upper working rollers 321, and the lower roller system 310 includes a plurality of lower working rollers 311. The plurality of upper working rollers 321 and the plurality of lower working rollers 311 jointly define a wedge-shaped deformation space in the working space 12.

[0038] That is, the plurality of upper working rolls 321 and the plurality of lower working rolls 311 are respectively located in the working space 12 , and the plurality of upper working rolls 321 are located above the plurality of lower working rolls 311 , and a wedge-shaped deformation space is formed between the outer circumferential surfaces of the plurality of upper working rolls 321 and the outer circumferential surfaces of the plurality of lower working rolls 311 .

[0039] The opening of the wedge-shaped deformation space increases toward the horizontal inlet and outlet 11, that is, the distance between the upper working roll 321 and the lower working roll 311 in the vertical direction increases toward the right. The upper frame 200 can rotate relative to the lower frame 100 to adjust the size of the horizontal inlet and outlet 11 and the wedge-shaped deformation space, so that the plate body 21 with different deformations can enter and exit the wedge-shaped deformation space through the horizontal inlet and outlet 11, and by adjusting the size of the wedge-shaped deformation space, the pressing amount and pressure of the cathode straightening device 10 can be adjusted to ensure the straightening effect.

[0040] For example, Figure 2 As shown, the opening degree γ of the wedge-shaped deformation space is the angle between the arrangement plane of the multiple upper working rollers 321 and the arrangement plane of the multiple lower working rollers 311. The value range of γ can be -1° to +20°. The size of the wedge-shaped deformation space can be controlled by changing the size of γ, so as to adapt to different board surface deformations of the plate body. The inventor of the present application has found through research that a cathode plate with known material properties corresponds to a specific value of the γ angle. Through preliminary calculations and experiments, the specific value of the γ angle can be obtained as a reference value. According to different board surface deformation conditions, the value of γ fluctuates around the reference value.

[0041] The left end of the upper frame 200 and the left end of the lower frame 100 can be hinged through a rotating shaft to achieve relative rotation between the upper frame 200 and the lower frame 100. The upper frame 200 driving assembly is respectively connected to the upper working roller 321 and the lower working roller 311, for example, the driving mechanism can be a motor or a hydraulic motor.

[0042] The following describes in detail the straightening process of the cathode straightening device 10 according to the embodiment of the present invention, wherein only the upper frame 200 rotates and the lower frame 100 is fixed as an example for relevant description.

[0043] Before the cathode 20 is sent into the wedge-shaped deformation space, the upper frame 200 is opened at a certain angle relative to the lower frame 100, so that a certain distance is generated between the upper working roller 321 and the lower working roller 311, so that the plate body 21 can be sent between the upper working roller 321 and the lower working roller 311, and the conductive rod 22 is parked outside the wedge-shaped deformation space;

[0044] After the plate body 21 is delivered to the working position between the upper working roll 321 and the lower working roll 311, the opening between the upper frame 200 and the lower frame 100 is adjusted to change the pressing amount and pressure of the upper working roll 321, so that the plate body 21 is deformed to a certain extent;

[0045] The upper frame 200 is locked after the plate body 21 reaches the set deformation amount, and the driving assembly drives the upper working roller 321 and the lower working roller 311 to rotate, so that the plate body 21 moves in the opposite direction to the feeding direction. The plate body 21 undergoes repeated positive or reverse bending deformation between the lower working roller 311 and the upper working roller 321, and the residual bending is gradually eliminated to straighten the plate body 21. In the above straightening process, due to the certain angle between the lower working roller 311 and the upper working roller 321, the deformation of the plate body 21 decreases in the direction close to the conductive rod 22 (for example, linearly decreasing). Finally, the plate body 21 is bitten out from the horizontal inlet and outlet 11.

[0046] According to the cathode straightening device 10 of the embodiment of the present invention, a wedge-shaped deformation space with a gradually increasing opening is pre-defined. Compared with the prior art, there is no need to set up an additional lifting mechanism 30 to control the lifting and lowering of the upper roller system 320. It has a simple structure, fewer movements, higher precision and better straightening effect. By relative rotation of the upper frame 200 and the lower frame 100, the size of the horizontal inlet and outlet 11 can be adjusted, so that it can be suitable for the straightening of plates 21 with different deformations, and the adjustment is more flexible.

[0047] According to some embodiments of the present invention, Figure 1 As shown, the lower frame 100 is provided with a lower mounting groove 101, the upper frame 200 is provided with an upper mounting groove 201, the lower roller system 310 is installed in the lower mounting groove 101, and the upper roller system 320 is installed in the upper mounting groove 201, and the lower mounting groove 101 and the upper mounting groove 201 jointly define a working space 12.

[0048] Specifically, the upper mounting groove 201 is open downward and penetrates front to back, and the lower mounting groove 101 is open upward and penetrates front to back. The horizontal inlet and outlet 11 is located on the right side of the working space 12, and the horizontal inlet and outlet 11 is defined by the lower surface of the upper mounting groove 201 of the upper frame 200 and the upper surface of the lower mounting groove 101 of the lower frame 100, and the horizontal inlet and outlet 11 connects the working space 12 with the outside. In this way, the upper roller system 320 and the lower roller system 310 are installed smoothly, the cathode 20 is convenient to be fed in and out, and the size of the horizontal inlet and outlet 11 and the wedge-shaped deformation space is convenient to be adjusted.

[0049] According to some embodiments of the present invention, Figure 1 As shown, the opening of the wedge-shaped deformation space is opposite to the horizontal inlet and outlet 11, that is, the central plane of the wedge-shaped deformation space coincides with the central plane of the horizontal inlet and outlet 11. For example, the opening of the wedge-shaped deformation space is to the right. In this way, the cathode 20 can be smoothly bitten out.

[0050] According to some embodiments of the present invention, Figure 1 As shown, the upper roller system 320 is tilted relative to the lower roller system 310 so that the plurality of upper working rollers 321 are tilted relative to the plurality of lower working rollers 311, thereby forming a wedge-shaped deformation space. For example, the upper roller system 320 is installed in the upper mounting groove 201, and a wedge block 210 can be arranged in the upper mounting groove 201, and the wedge block 210 is clamped between the upper roller system 320 and the inner wall of the upper mounting groove 201; or, the top wall of the upper mounting groove 201 can be tilted upward and to the right. In this way, the structure is simple.

[0051] According to some embodiments of the present invention, Figure 1 As shown, the plurality of lower working rolls 311 are arranged on a horizontal plane, and the plurality of upper working rolls 321 are arranged on an imaginary inclined plane. For example, the central axes of the plurality of upper working rolls 321 and the central axes of the plurality of lower working rolls 311 extend in the front-rear direction respectively, and the plurality of upper working rolls 321 and the plurality of lower working rolls 311 are arranged at intervals in the left-right direction respectively, wherein the installation height of the plurality of upper working rolls 321 increases from left to right. In this way, the selectable structures are more diverse.

[0052] According to some embodiments of the present invention, Figure 1 As shown, the central axis of the upper working roll 321 and the central axis of the lower working roll 311 extend in the horizontal direction (e.g., the front-rear direction), and the central axis of the upper working roll 321 and the central axis of the lower working roll 311 are staggered in the up-down direction. In other words, the upper working roll 321 and the lower working roll 311 are staggered. In this way, the plate body 21 can be repeatedly deformed in two directions, and the straightening effect is better.

[0053] It is understandable that Figure 2As shown, the area of ​​the plate 21 close to the conductive rod 22 and covered by the upper working roller 321 is a straightening blind area. When the diameter of the working roller is larger or the number of working rollers is more, the straightening blind area becomes larger, and the deformation of the plate 21 in the straightening blind area cannot be straightened. However, the applicant has studied the deformation of a large number of plate bodies 21 and found that the plate 21 in the limited area close to the conductive rod 22 has greater rigidity and strength after being welded to the conductive rod 22, so the plate 21 in this area has almost no deformation or the deformation is within the process requirements. For this reason, the rational selection of the number and diameter of the working rollers can improve the straightening effect.

[0054] Alternatively, if Figure 1 As shown, the total number of the upper working rolls 321 and the lower working rolls 311 is not less than 5. For example, the number of the upper working rolls 321 is 3 and the number of the lower working rolls 311 is 4. In this way, the straightening effect is further improved.

[0055] Optionally, the working roll diameters of the upper working roll 321 and the lower working roll 311 are 20 mm to 90 mm. In this way, the straightening effect can be further improved.

[0056] According to some embodiments of the present invention, Figure 1 As shown, the cathode straightening device 10 further includes: a lifting mechanism 30 for driving the upper frame 200 to rotate. The first end (e.g., the left end) of the upper frame 200 is movably connected to the first end (e.g., the left end) of the lower frame 100, the lower end of the lifting mechanism 30 is movably connected to the second end of the lower frame 100, and the upper end of the lifting mechanism 30 is movably connected to the second end of the upper frame 200. For example, the upper end and the lower end of the lifting mechanism 30 are hinged to the right end of the upper frame 200 and the right end of the lower frame 100, respectively. In this way, when the cathode 20 enters between the lower working roller 311 and the upper working roller 321, the upper working roller 321 squeezes the plate body 21 under the descending action of the lifting mechanism 30, so that the plate body 21 is deformed, so that the pressing amount and the pressure can be accurately controlled, and the operation is convenient and the mechanization degree is high.

[0057] In some embodiments of the present invention, Figure 1 As shown, the horizontal inlet and outlet 11 is located between the working space 12 and the lifting mechanism 30 in the horizontal direction. In this way, it is more convenient to use and has a more compact structure.

[0058] In some embodiments of the present invention, Figure 1As shown, the lifting mechanism 30 is constructed as a lifting mechanism 30 with adjustable length in the up-down direction, for example, the lifting mechanism 30 is retractable in the up-down direction. The lifting mechanism 30 may be a screw mechanism, a hydraulic cylinder, an electro-hydraulic push rod, etc. It can be understood that the double screw lifter can make the mechanical synchronization of the rise or fall of the upper frame 200 better than that of the double hydraulic cylinder. This synchronization is particularly important for the extrusion deformation applied to the plate body 21, which can make the force and the pressing amount of the plate body 21 uniform, and according to experiments, no deviation occurs when the plate body 21 comes out.

[0059] Other structures and operations of the cathode straightening device 10 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.

[0060] According to the cathode straightening method of the cathode straightening device 10 of the second aspect of the present invention, the method comprises:

[0061] First, the upper frame 200 is opened to a preset angle relative to the lower frame 100. Subsequently, the plate body 21 is fed into the wedge-shaped deformation space through the horizontal inlet and outlet 11, and the conductive rod 22 is placed outside the wedge-shaped deformation space. Afterwards, the pressing amount and pressure of the upper roller system 320 are adjusted by adjusting the angle at which the upper frame 200 is opened relative to the lower frame 100. Finally, when the plate body 21 reaches a preset deformation amount, the relative positions of the upper frame 200 and the lower frame 100 are fixed, and the driving assembly drives the upper working roller 321 and the lower working roller 311 to rotate in a direction that moves the plate body 21 in the opposite direction to the feeding direction.

[0062] Specifically, when the plate body 21 is sent to the left into the wedge-shaped deformation space, the upper working roller 321 squeezes the plate body 21 under the descending action of the lifting mechanism 30, causing the plate body 21 to deform. The upper frame 200 is locked after the lifting mechanism 30 descends a certain distance. Driven by the driving assembly, the upper working roller 321 rotates counterclockwise, and the lower working roller 311 rotates clockwise. The plate body 21 undergoes repeated positive or reverse bending deformation between the lower working roller 311 and the upper working roller 321, gradually eliminating the residual bend and straightening the plate body 21, and the plate body 21 is sent to the right. Since the lower working roller 311 and the upper working roller 321 form a certain angle, the plate surface deformation of the plate body 21 decreases linearly from the left end to the right end close to the conductive rod 22.

[0063] According to the cathode straightening method of the cathode straightening device 10 of the embodiment of the present invention, the upper frame 200 can be rotated to open a larger opening under the driving action of the lifting mechanism 30 to accommodate the cathode 20 with large deformation to be sent between the lower working roller 311 and the upper working roller 321 manually or automatically. The rotation of the upper frame 200 can also achieve extrusion deformation on the cathode 20, and the upper working roller 321 is pre-tilted, and there is no need to set an additional lifting and pressing mechanism to drive the upper working roller 321 to lift and lower, so the structure is simple and the action is less. In addition, the parallel roller straightening principle is adopted to straighten the plate surface of the damaged or deformed cathode 20 with the conductive rod 22, eliminating the separation process of the conductive rod 22 and the plate body 21, improving the repair efficiency and utilization rate of the cathode 20, and reducing the repair cost and labor intensity.
