Description

Technical Field

[0001] This utility model relates to the field of anode plate milling technology, and in particular to an electrode plate milling device for a copper electrolytic anode shaping unit. Background Technology

[0002] The anode plate is the core electrode component in the electrolysis process. Connected to the positive terminal of the power supply, it undergoes an oxidation reaction during electrolysis and is widely used in electrostatic precipitators, electrolytic metallurgy, electroplating, wastewater treatment, seawater desalination, and fuel cells. Anode plate milling is a precision milling process performed on the outer ears of the anode plate during electrolysis. It aims to correct geometric deviations in the outer ears through machining, optimizing their conductivity, suspension, and sealing performance. This is a key technical step in anode plate preparation. After the anode plate undergoes ear pressing, weighing, and plate shaping, it is transferred to the milling head via a transfer device. Once the anode plate reaches the bottom milling area, the ear clamps and plates sequentially clamp the anode plate, and the milling cutter mills the bottom of the outer ears.

[0003] In the existing anode plate milling process, because the anode plate is cast using pyrometallurgical methods, the depth of the concave ears on the side of the large ear is difficult to control. During bottom milling, the clamping device easily gets caught on the upper edge of the concave ear, lifting the anode plate a certain distance. This results in the bottom of one side of the outer ear not being milled effectively, causing it to enter the tank surface, leading to an excessive number of copper nails used and a decrease in the quality of electrolytic copper. Insufficient milling at the bottom of the outer ear will cause the parallelism and perpendicularity deviation between the anode plate suspension surface and the conductive plate to increase. This will directly disrupt the uniform current distribution in the electrolytic cell, causing excessively high current density in some areas, leading to excessive anode corrosion, or excessively low current density, leading to a decrease in electrolytic efficiency.

[0004] To address the issue of the clamping lugs easily getting stuck on the upper edge of the concave lugs, resulting in uneven milling of one side of the outer lug bottom during bottom milling, two iron blocks (70mm long × 40mm wide × 10mm thick) were fabricated and welded to the top side of the clamping lugs. This ensures that the iron blocks maintain parallel contact with the anode plate during clamping. This parallel contact design optimizes the traditional point contact to a surface contact, expanding the contact area from a localized area of ​​the original clamping lug to a 40×10mm plane. This results in a more uniform distribution of contact pressure, preventing clamping tilting or slippage caused by varying concave lug depths. Furthermore, the iron blocks, acting as rigid supports, can withstand greater clamping forces without deformation, ensuring the anode plate remains fixed during milling, reducing displacement due to vibration or cutting forces, and guaranteeing consistent milling depth at the bottom of the outer lugs.

[0005] However, existing milling cutters, when milling the bottom of the outer ear, result in inconsistent milling angles due to variations in anode plate width. This can lead to inconsistent milling curvature of the anode plate. Differences in anode plate width necessitate frequent adjustments to the milling angle. Without dynamic compensation, the curvature of the outer ear bottom may become an irregular surface. Inconsistent curvature increases contact resistance, with localized heating temperatures reaching 120-150℃. This can cause anode plate oxidation, electrolyte carbonization, and even thermal stress leading to solder joint meltdown or anode plate cracking, increasing safety risks such as short circuits and fires. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an electrode plate milling device for a copper electrolytic anode shaping unit. This device solves the problem that the clamping ear is easily clamped on the upper edge of the concave ear, resulting in the inability to guarantee the milling effect on the bottom of one side of the outer ear during bottom milling.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A plate milling device for a copper electrolysis anode shaping unit includes an anode plate body. Two clamping ear structures are symmetrically arranged on the upper sides of both sides of the anode plate body. An iron block is fixedly connected to the bottom end of each clamping ear structure. A soft pad is provided on the side of each iron block closest to the anode plate body. The iron block ensures that the milling process does not affect the shaping quality due to the deep recesses of the anode plate body's ears during bottom milling. The soft pad prevents friction between metal parts. As a rigid clamping component, the iron block, through its bottom surface contacting the plane of the ear portion of the anode plate body, effectively counteracts localized stress concentration caused by the deep recesses of the ears.

[0009] As a further improvement of this utility model, each of the soft pads has a threaded rod fixedly connected to its center near the adjacent iron block, and each iron block has a threaded groove at its center near the soft pad. The threaded rod and the threaded groove are connected by threads. The threaded connection allows for fine adjustment of the relative position of the soft pad and the iron block by rotating it, thereby compensating for manufacturing errors or accumulated assembly errors.

[0010] As a further improvement of this utility model, the clamping ear structure is symmetrically and fixedly connected to two sliding rods on one side close to each other. A connecting plate surface one is slidably connected to the two sliding rods on the same side close to each other. A connecting driving rod is fixedly connected to the bottom end of each sliding rod, and the two connecting driving rods are symmetrical along the sliding rods. A sliding plate is fixedly connected to the bottom end of each connecting driving rod. A connecting plate surface two is slidably connected to the side close to each other of the two sliding plates, and the two sliding plates are symmetrical along the connecting plate surface two. The sliding rods and connecting plate surface one, and the sliding plates and connecting plate surface two, form a two-stage sliding guide structure. Precision machining ensures that the clamping ear structures on both sides remain synchronized during movement.

[0011] As a further improvement of this utility model, a stop spring is fixedly connected to the center of the top end of the second connecting plate, and a telescopic rod is fixedly connected to the center of the stop spring at the top end of the second connecting plate. The top ends of both the stop spring and the telescopic rod are fixedly connected to the center of the bottom end of the first connecting plate. The stop spring can automatically adjust its compression according to the thickness change of the anode plate ear, so that the clamping force is stabilized near the design value.

[0012] As a further improvement of this utility model, the sliding plate is designed with an inclined angle on the side near the clamping ear structure. The inclined angle is used to keep the milling angle constant when the milling cutter mills the bottom of the outer ear of the clamping ear structure. The inclined angle design ensures that the sliding plate always forms a fixed angle with the milling cutter axis during the movement of the clamping ear structure.

[0013] As a further improvement of this invention, the height of the iron block is between 40 and 70 mm. A taller iron block, by increasing its mass and moment of inertia, can effectively attenuate milling vibrations.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] 1. By designing the iron block to make parallel contact with the anode plate body, the traditional point contact is optimized into surface contact. The contact area is expanded from the local area of ​​the original clamping lug to a 40×10mm plane, resulting in a more uniform distribution of contact pressure and avoiding clamping tilting or slippage caused by uneven depth of the recessed lug. Moreover, the parallel contact design of the iron block ensures that the perpendicularity error between the bottom of the anode plate's outer lug and the milling cutter is ≤0.1mm, and the flatness error is ≤0.05mm, meeting the processing requirements of high-end electrolytic copper.

[0016] 2. The constant position design of the sliding plate and clamping lug structure ensures that the milling angle remains fixed regardless of changes in the width of the anode plate. The sliding rod can cover anode plates of different widths along the sliding range of the connecting plate surface. Driven by the connecting rod, the sliding plate adjusts its position synchronously, ensuring automatic matching of clamping and milling parameters. Attached Figure Description

Detailed Implementation

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0024] See attached document Figure 1 -Appendix Figure 4 A plate milling device for a copper electrolysis anode shaping unit includes an anode plate body 100, an iron block 202, a soft pad 203, a connecting plate 305, a contact spring 306, and a telescopic rod 307.

[0025] In this embodiment, milling ears on anode plate bodies 100 of different widths is taken as an example. When using this invention, the anode plate body 100, after being pressed, weighed, and shaped by the pressure plate, is first placed at the bottom of the connecting plate surface 305. The elastic properties of the contact spring 306 press the anode plate body 100 under the connecting plate surface 305. The elastic design of the connecting plate surface 305 can adapt to anode plate bodies 100 of different widths. Through the elastic adjustment of the contact spring 306, the clamping force is ensured to be evenly distributed, avoiding clamping tilt or loosening due to width differences. The elastic properties of the contact spring 306 can adapt to the problem of varying recess depths, ensuring that the iron block 202 and the bottom of the outer ear of the anode plate body 100 remain in parallel contact during clamping, avoiding uneven local force caused by clamping on the upper edge of the recess.

[0026] Then, the clamping ear structure 201 is used to fix the anode plate body 100. The fixing method of the clamping ear structure 201 is prior art and will not be described in detail here. The iron block 202 fixed to the bottom of the clamping ear structure 201 fixes the anode plate body 100. Then, the iron block 202 is threadedly connected to the threaded rod 204 through the threaded groove 205. The soft pad 203 is fixed to the end of the threaded rod 204 near the anode plate body 100. This ensures that while the anode plate body 100 is fixed by the square iron block 202, the soft pad 203 also prevents direct contact between the metal and the anode plate body 100. The soft pad 203 acts as a buffer layer to prevent the metal of the iron block 202 or the threaded rod 204 from directly scraping the surface of the anode plate body 100. The uniform pressing of the soft pad 203 ensures that the bottom of the outer ear of the anode plate body 100 maintains a constant angle with the milling cutter, reducing the milling curvature deviation caused by unstable clamping.

[0027] As the clamping lugs 201 approach each other, the sliding rod 301 slides along the connecting plate surface 302. Since the sliding rod 301 and the sliding plate 304 are connected by a connecting rod 303, the sliding plate 304 slides along the connecting plate surface 305 under the influence of the sliding rod 301. Because the position of the sliding plate 304 relative to the clamping lugs 201 is constant, the milling angle of the anode plate body 100 is fixed when milling anode plate bodies 100 of different widths. The constant position design of the sliding plate 304 and the clamping lugs 201 ensures that the milling angle remains constant regardless of changes in the width of the anode plate body 100. The sliding range of the sliding rod 301 along the connecting plate surface 302 can cover anode plates of different widths. Through the transmission of the connecting rod 303, the sliding plate 304 adjusts its position synchronously, ensuring automatic matching of clamping and milling parameters.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
