Under the condition that the electroplating layer reaches 3um, the current density can continue to increase, so that the high-speed steel The speed of the belt continuous nickel plating unit has also been further increased.
[0047] The working process of the present invention is as follows:
[0048] First of all, when the production line is in normal production, the steel strip 10 runs in one direction in the working tank. At this time, the door 1 is closed, the conductive roller 9 is connected to the cathode power supply and transmitted to the steel strip 10, the anode bridge 14 is connected to the anode power supply, and the anode bridge is connected. The anode assembly 11 is composed of a titanium basket and an anode bag. The nickel block is contained in the titanium basket. At this time, the nickel block is connected to the anode power supply, and the electroplating solution is supplied by the pump and enters the working tank from the electroplating solution inlet pipe 12-1. , and is sprayed between the anode and the cathode by the nozzle 13. After the liquid level of the electroplating solution reaches a certain high level, it all flows into the reflux tank 15, and then overflows into the underground storage tank through the overflow port 8 through the reflux tank. cycle. After the steel strip connected with the cathode power supply enters the working tank, due to the action of the current and the electroplating solution, nickel ions are deposited on the cathode steel strip 10, and the steel strip 10 is plated with nickel.
[0049] When the working tank needs maintenance, just shut down the electroplating solution pump, turn off each power supply, open the four drain ports 6 on the side, and drain the electroplating solution into the underground storage tank. After the electroplating solution is finished, the door can be locked quickly The handle 3-4 of the mechanism 3 opens the door, and the internal parts of the working tank can be cleaned, washed and maintained, and the devices such as the conductive roller 9 need not be disassembled. Specifically, the underground storage tank is located in a tank body in the basement of the equipment, and the working tank is two separate parts. It is mainly used for the storage and circulation of the electroplating solution. After the normal shutdown, the electroplating solution in the working tank will be discharged into the underground. In the storage tank, the electroplating solution is also added to the underground storage tank before starting the machine. During normal startup, the electroplating solution is pumped from the underground storage tank to the electroplating solution inlet pipe assembly 12 and sprayed into the working tank through the nozzle. Liquid can be recycled.
[0050] like Figure 10 As shown in the figure, when it is necessary to replace the anode assembly 11 or add a nickel block, just remove the connecting screw on the transmission side of the anode bridge 14. Since the anode bridge is hung on the bracket of the tank body, it is only necessary to use the trolley support arm 18 to hold up the anode bridge 14. , and then slowly move out to the operating side. The auxiliary trolley 17 can be placed on one side of the tank body 4 and has the function of moving in six directions: up and down, left and right, and front and back. When the anode bridge 14 inside the tank body 4 and the anode assembly 11 connected below are removed, directly replace the new anode assembly prepared in advance, and then lift the anode bridge and the new anode assembly through the trolley support arm 18 and reload it into the Just specify the location. At present, the auxiliary trolley can hold four anode assemblies at a time, which greatly shortens the time for each anode assembly replacement or maintenance, so that the maintenance and replacement of anode assemblies or nickel addition time is only a quarter of the original time, which greatly improves the work efficiency.
