technical field

The utility model belongs to the technical field of electroplating equipment and relates to equipment for continuous electroplating of wire rods.

Background technique

In industrial production, it is sometimes necessary to coat the surface of the wire with a layer of material different from the base layer in terms of material and performance, which is used as a functional layer or a protective layer. At present, electroplating is mostly used. The wire rod has high requirements on the uniformity and continuity of the plating layer. The traditional static plating method cannot meet the requirements. At present, the wire rod moves at a constant speed and the continuous plating method is generally used, such as wire galvanization, copper plating, etc., but this continuous electroplating The machine requires the resistance of the wire and solution to be low, and the electroplating workshop should be long enough, otherwise the thickness of the coating cannot be guaranteed. The current continuous wire electroplating equipment used by manufacturers usually can only move the wire in one direction, that is, the wire enters from one end of the main plating tank and continues to move forward in the electroplating solution until it is removed from the main plating tank to complete the electroplating process.

When the wire is electroplated with zinc and copper, due to the good conductivity of the electroplating solution and the wire, the adjustable range of the current, and the adjustable moving speed of the wire, the thickness of the coating can generally be guaranteed. However, when electroplating iron, the conductivity of the electroplating solution is poor. In addition, an asymmetrical AC and DC power supply is also used during electroplating, and the thickness of the coating cannot meet the requirements. In addition, if the material of the wire is nickel-based alloy, the resistance of the wire is relatively high, and the thickness of the coating cannot meet the requirements when the electroplating machine is used again.

Wherein, as shown in Figure 3, main plating device comprises main plating tank 11 and the main plating wire roll 15 that is arranged in main plating tank 11, and main plating tank 11 is divided into upper and lower two layers, and i.e. upper floor main plating tank 11-1 and The lower main plating tank 11-2, the main plating wire roller 15 is located in the lower main plating tank 11-2, the bottom of the upper main plating tank 11-1 is provided with a main plating anode plate 12, the main plating anode plate 12 and the main plating anode plate The terminal 13 is connected, and the main plating tank 11-2 of the lower floor is also similarly provided with the main anode plate 12 to be connected with the main anode plate terminal 13, and the bottom of the upper main plating tank 11-1 is provided with a discharge valve 10. When the equipment is out of service, the electroplating solution in the tank will be put into the liquid storage tank below the plating tank by the drain valve 10 to prevent pollution.

The upper main plating tank 11-1 is also provided with a discharge tank 14. When the electroplating equipment is working, the electroplating solution will be injected into the main plating tank from the storage tank by the pump, and the overflowing liquid in the main plating tank will pass through the main plating tank. The discharge tank 14 flows into the liquid storage tank below the plating tank, so as to realize the circulation process. The height of the liquid baffle plate 21 of the discharge tank 14 is 0.5-1 mm lower than the upper end plane of the two wire rollers, as shown in Figure 6. Line branch bar 20 is housed on the baffle.

The wire take-up device includes an alkali washing tank 16 , a third water washing tank 17 , a drying box 18 and a wire take-up rack 19 arranged in sequence.

The working process of the utility model is that the wire to be plated is placed on the pay-off frame 1. After the wire is unwound, the wire first enters the activation tank 2 for activation, and then after being cleaned by the first washing tank 3, it enters the pre-plating tank for pre-plating. After pre-plating, it enters the main plating tank after being cleaned by the water washing tank 8, and then after 80 to 100 circles of reciprocating motion, the main plating process is completed, and then enters the alkaline washing tank 16 to neutralize the remaining plating solution on the surface, and then goes through the third water washing Groove 17 is cleaned, and finally enters drying box 18 to dry, and the electroplating wire rod of drying completes the electroplating process of whole wire rod behind the take-up frame 19.

The pickling activation device and the pre-plating tank in the pre-plating device of the present utility model adopt the design of guide rollers respectively, and the wire rod can reciprocate 10 to 20 turns in the solution, thus ensuring the activation and pre-plating effect. The coating with excellent binding force provides a guarantee. In the pre-plating process, the conductive carbon brush 7 is connected to the guide roller and the power supply to continuously supply power to the cathode wire; the positive pole of the power supply is connected to the pre-plating anode plate terminal 6 to continuously supply power to the anode plate. In order to ensure the quality of the coating, the solutions in these two links are circulated through pumps respectively.

When using the new structure design of the main plating part, the main plating tank 11 is divided into upper and lower layers. When plating, the wire is evenly distributed on the two wire rollers under the action of the wire rod, and then guided by the wire rollers, the main plating tank 11 is divided into upper and lower layers. The tank reciprocates until the wire moves out of the main plating tank. The height of the liquid baffle plate 21 in the drain tank should be 0.5-1mm lower than the upper plane of the two wire rollers, so as to ensure that when the main plating tank is filled with liquid and the liquid is continuously discharged from the drain tank, the wire can be completely immersed in the electroplating solution , and ensure that the wire does not touch the baffle when it moves. The main plating wire roller 15 is connected to the negative pole of the power supply through the conductive carbon brush 9, and supplies power to the cathode wire; the main plating anode plate 12 is connected to the positive pole of the power supply through the main plating anode plate terminal 13, and supplies power to the anode material. This part of the electroplating solution is injected into the main plating tank 11 through the pump from the lower part of the main plating tank to store the electroplating solution, and then flows into the liquid storage tank below the equipment through the drain tank 14 and the drain valve 10, thereby completing the circulation process. The power of this part of wire roller is provided by two synchronously rotating motors.

In order to shorten the overall equipment length, the take-up section is placed parallel to the pre-plating. Both the incoming and outgoing wires are on the same side of the main plating tank, which is realized by the wire rollers at both ends of the main plating tank. The specific winding method is shown in Figure 5. In addition, the lye in this part of the alkali washing tank 16 can also be circulated through the pump, thereby minimizing the pollution of the lye.
