Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cobalt, in particular to a clamping device for preventing warping of an electrolytic cobalt starting electrode sheet. Background Art

[0002] Currently, the electrolytic cobalt (nickel) industry primarily uses starter sheets as cathode plates for electrolytic cobalt (nickel) products. Due to the thinness of these starter sheets, the bottom corners are prone to curling during the deposition process, resulting in high stress and strain. This also leads to stress deformation and bending on the plate surface during electroplating, leaving the cobalt plate as a "turtle shell." When the cathode has a plate frame, the electrolytic cobalt grows into the frame, affecting the deposition efficiency. When the cathode has no plate frame, it causes a short circuit between the cathode and the cathode, leading to plate burns and impacting electrical efficiency. This also significantly affects subsequent cobalt plate cutting and affects the product's appearance and quality.

[0003] Therefore, in order to solve the above problems, it is necessary to provide a clamping device for the starting electrode to prevent the edge from warping. The starting electrode should be fixed before electrolysis. After the electrolytic cobalt plate is formed after a certain period of electrolysis, the clamping device can be removed. The clamping device needs to be firmly fixed and easy to disassemble and assemble. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology, and to propose an anti-warping clamping device that is firmly fixed and easy to disassemble and install. After use, the efficiency and quality of the starting electrode slotting can be improved, the labor of subsequent plate surface leveling, short circuit processing and finished cobalt plate cutting can be reduced, and the quality of electrolytic cobalt products can be improved.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A clamping device for preventing warping of an electro-cobalt starting electrode comprises a starting electrode, wherein a front clamping frame and a rear clamping frame are respectively nested at the front and rear ends of the outer side of the starting electrode, and the outer walls of the front clamping frame and the rear clamping frame are both provided with fixing plates, and rivets are embedded in the interior of the fixing plates, and tail spikes are fixed on the back of the rivets.

[0007] Preferably, the starting pole piece is tightly attached between the front clamping frame and the rear clamping frame, and the size of the edge of the starting pole piece and the outer edges of the front clamping frame and the rear clamping frame is 5 mm.

[0008] Preferably, eight fixing plates are provided on the outer sides of the front clamping frame and the rear clamping frame, and the fixing plates are distributed at the four corners and the midpoints of the four outer edge lines of the front clamping frame and the rear clamping frame.

[0022] Example 1, with reference to Figure 1-4 A clamping device for preventing the warping of an electric cobalt starting electrode includes a starting electrode 6, which is characterized in that a front clamping frame 1 and a rear clamping frame 2 are respectively nested on the front and rear ends of the outer side of the starting electrode 6, and the outer walls of the front clamping frame 1 and the rear clamping frame 2 are both provided with a fixing plate 3, and rivets 4 are embedded in the interior of the fixing plate 3, and tail spikes 5 are fixed on the back of the rivets 4.

[0023] The starting pole piece 6 is tightly attached between the front clamping frame 1 and the rear clamping frame 2, and the edge of the starting pole piece 6 and the outer edge of the front clamping frame 1 and the rear clamping frame 2 are 5mm apart;

[0024] Eight fixing plates 3 are provided on the outside of the front clamping frame 1 and the rear clamping frame 2. The fixing plates 3 are distributed at the four corners and the midpoints of the four outer edge lines of the front clamping frame 1 and the rear clamping frame 2;

[0025] The eight fixing plates 3 can improve the stability of the starting electrode 6 fixed between the front clamping frame 1 and the rear clamping frame 2;

[0026] The fixing plate 3 provided on the outer side of the front clamping frame 1 is located just at the front end of the fixing plate 3 provided on the outer side of the rear clamping frame 2;

[0027] After the tail thorn 5 of the rivet 4 is embedded in the fixing plate 3 of the front clamping frame 1, it will be embedded in the fixing plate 3 of the rear clamping frame 2, so that the front clamping frame 1 and the rear clamping frame 2 are firmly fixed together;

[0028] The middle part of the fixing plate 3 is provided with a threaded hole, and the tail thorn 5 on the back of the rivet 4 is just embedded in the threaded hole inside the fixing plate 3, and the external thread on the outer wall of the tail thorn 5 is engaged with the thread inside the threaded hole;

[0029] When the tail spike 5 on the back of the rivet 4 is embedded in the fixing plate 3 of the front clamp frame 1 and the rear clamp frame 2, the external thread on the outer wall of the tail spike 5 engages with the thread inside the threaded hole, thereby firmly fixing the starting pole piece 6 between the front clamp frame 1 and the rear clamp frame 2.

[0030] Example 2. Example 2 differs from Example 1 in that, in this example, the front clamp frame 1, the rear clamp frame 2 and the fixing plate 3 are all made of hard or semi-hard fiberglass, and the rivets 4 and the tail spikes 5 are made of elastic PEEK.

[0031] When the starting electrode 6 is formed after a period of electrolysis and needs to be removed from the clamping device, pinch the rear end of the tail spike 5 on the rivet 4, and pull the rivet 4 and the tail spike 5 out of the fixed plate 3 from the back to the front to realize the frame disassembly operation of the device, which makes it easier to remove the starting electrode 6 later.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
