Technical Field
[0001] This utility model relates to the field of electrode plate stamping and riveting technology, specifically to a solder electrolytic cathode plate stamping and riveting fixing device. Background Technology
[0002] In the field of non-ferrous metal electrolytic refining, the cathode plate is the reducing electrode in electrolytic smelting. Its main function is to reduce metal cations in the electrolyte during electrolysis. It must have good conductivity and sufficient strength. In the electrolytic refining process of large electrode plates, the cathode plate is generally made of a combination of solder sheet and copper rod. In existing solder electrolytic electrode plate technology, the preparation method of lead electrolytic electrode plate is generally adopted. The solder strength is higher than that of pure lead material, and due to the lack of corresponding fixing technology, serious eccentricity problems are easily generated after riveting. For example, the Chinese utility model patent "A riveting device for a starting plate" (publication number CN206241091U) describes the existing common electrode plate riveting equipment, which includes a frame, riveting device I, lower support I, riveting frame, guide rod I, fixing parts, connecting parts, piston rod, and stamping cylinder. Guide rod II, lower bracket II, and riveting device II; the stamping cylinder is mounted on the upper part of the frame, guide rod I and guide rod II are respectively mounted on the frame, and the connecting piece is installed on the lower part of the stamping cylinder. The riveting frame is connected to the stamping cylinder through guide rod I, guide rod II, fixing piece, and connecting piece. Lower bracket I and lower bracket II are respectively mounted on the frame and located at the lower part of the riveting frame. The upper parts of riveting device I and riveting device II are mounted on the riveting frame, and the lower parts of riveting device I and riveting device II are respectively mounted on the lower part of the frame. During the riveting process, there is a lack of corresponding fixing and clamping measures. Furthermore, because the solder strength is higher than that of pure lead, it is prone to causing eccentricity problems after riveting. Figure 1 As shown, the contact conductivity between copper and solder sheet is low. Therefore, it is necessary to ensure that the solder sheet tightly wraps around the copper rod to increase the contact area. As a result, the eccentricity problem will cause problems such as inaccurate electrode spacing, increased contact resistance of copper rod, and electrode plate tearing during electrolysis. How to overcome the problem of precise fixing of the two during the stamping and riveting process of solder electrolysis cathode plate, and to make the solder sheet and copper rod fit as tightly as possible, is a difficult problem that the industry has been exploring.

One end of the compression spring I 801 presses against the shaft of the copper plate pressure rod 8, and the other end presses against the positioning pressure plate 802. By adjusting the bolt 803 and the nut, the distance between the positioning pressure plates 802 can be adjusted, thereby adjusting the retraction height of the compression spring I 801 and controlling the clamping force of the copper plate pressure rod 8. Figure 6 and Figure 7 As shown.
[0036] like Figure 2 , Figure 3 and Figure 4 As shown, an mounting sleeve 9 is also installed on the upper pressure plate 6. A riveting head 11 is installed inside the mounting sleeve 9. After the threaded shaft section at the top of the riveting head 11 passes through the through hole of the mounting sleeve 9, it is fastened by inner and outer nuts. At the same time, the height of the riveting head 11 inside the mounting sleeve 9 can be controlled by the nuts.
[0037] Inside the mounting sleeve 9 and outside the riveting head 11, a riveting pressure sleeve 10 is slidably installed, and the riveting top rod 5 passes through the support seat 2 and is correspondingly set with the riveting head 11.
[0038] A compression spring II 12 is mounted on the outside of the riveting head 11. The port of the riveting sleeve 10 is fastened to the mounting ring 13 by threads. The upper end of the compression spring II 12 is close to the shaft of the riveting head 11, while the lower end supports the mounting ring 13. The screw depth of the mounting ring 13 is adjustable, thereby controlling the elastic force of the compression spring II 12 and further realizing precise control of the pressing force of the riveting sleeve 10.

[0043] When using: such as Figures 6-8 As shown, the transport equipment delivers the solder sheet wrapped with copper rod into this equipment, and the copper rod enters the copper rod groove 201. At this time, the riveting cylinder 7 is started, driving the upper pressure plate 6 to move downward, and the copper plate pressure rod 8 firmly presses the solder-wrapped copper rod into the copper rod groove 201. Subsequently, the upper pressure plate 6 continues to press down, causing the riveting sleeve 10 to contact the workpiece and press the riveting part of the workpiece tightly. Then, the riveting head 11 is inserted into the workpiece, penetrating it and entering the riveting rod hole 202. All the power for the above actions is provided by the upper riveting cylinder 7. Immediately afterwards, the lower ejector cylinder 4 is activated, and its telescopic rod pushes the lower pressure plate 3 upward. At the same time, the riveting ejector 5 rises in the riveting rod hole 202, and the riveting head 11 enters the stamping cavity 501. The protruding edge 502 of the opening of the stamping cavity 501 flattens the flange generated by the penetration of the riveting head 11, completing the riveting action. Then, the riveting cylinder 7 retracts, driving the upper pressure plate 6 to move upward. The riveting head 11 and other components are pulled up and pulled out, and the workpiece is released. Finally, the ejector cylinder 14 operates, ejecting the copper rod from the copper rod groove 201. The lower ejector cylinder 4 returns to its position. Then, the workpiece is removed by the equipment of the next process.
