Description

Technical Field

[0001] The utility model relates to the field of copper-plated welding wire manufacturing, in particular to a copper-plated welding wire non-stop liquid-changing plating tank system. Background Art

[0002] There are currently two ways to produce copper-plated welding wire in the copper plating process, namely centralized expansion and online copper plating, but their process flows are the same. Here we briefly explain the process flow of copper-plated welding wire production using the online method. Figure 1 (Schematic diagram of the production process of copper-plated welding wire).

[0003] The production process of copper-plated welding wire: wire rod (double-station pay-off or other pay-off forms) - pre-treatment - wire drawing - copper plating - wire taking-up.

[0004] Because the surface of the welding wire needs to be pre-treated before copper plating, and also needs to be post-treated after copper plating, the copper plating process includes several process flows.

[0005] At present, in the electrolytic pickling and copper plating processes of the copper plating process, the pickling solution and the copper plating solution need to be stopped and replaced after exceeding the standards. Each replacement takes at least 6 hours, and the exceeding of the standards of the pickling solution and the copper plating solution often does not occur at the same time, but basically occurs at different times. This results in the need to stop the machine again to replace another solution after two or three shifts after just stopping the machine to replace one of the solutions. This further aggravates the reduction in production line utilization and employee productivity. Frequent shutdowns for long periods of time will lead to unstable product quality.

[0006] For example, after the machine is shut down, a small section of welding wire in the mold will cold harden, which will cause a jump in the rigidity and hardness of the welding wire. Moreover, restarting the machine after cold hardening may easily lead to wire breakage, further aggravating the decline in production efficiency and increasing losses. Utility Model Content

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] like Figure 1 The copper-plated welding wire non-stop liquid-changing plating tank system shown includes a dry-wiping module 100, and the dry-wiping module 100 includes a plurality of single dry-wiping machines 110 and 120 connected to each other at the end. The welding wire 1 enters the dry-wiping chambers 111 and 121 of the dry-wiping machines 110 and 120 from the wire inlet of the dry-wiping machine 110, and after dry-wiping, enters the first water-washing module 200 from the outlet of the dry-wiping machine 120.

[0033] The first water washing module 200 includes a first water washing tank 210, in which a water washing nozzle 220 is arranged. The welding wire 1 after dry wiping enters the water washing tank 210. A heating and pressurizing device 230 is arranged in the first water washing tank 210, and the water in the first water washing tank 210 is heated and pressurized by the heating and pressurizing device 230.

[0034] The welding wire 1 is cleaned by spraying water through the water washing nozzle 220, and the cleaned welding wire 1 directly enters the pickling module 300.

[0035] The pickling module 300 is provided with a first pickling liquid storage tank 310 and a second pickling liquid storage tank 320 for separate use (ie, a two-chamber pickling liquid storage tank, one for use and one for backup). The first pickling liquid storage tank 310 and the second pickling liquid storage tank 320 are both provided with separate return pipes 314 and 324 .

[0036] An independent lifting pump in a single tank is provided above the first pickling liquid storage tank 310 and the second pickling liquid storage tank 320 and is connected to a common acid liquid spray pipe 330 to form an acid liquid circulation loop, and the acid liquid is sprayed onto the welding wire 1 through the acid liquid spray pipe 330 .

[0037] The welding wire 1 is pickled by spraying acid through the acid nozzle 330, and the amount of acid sprayed can be adjusted by an independent lifting pump.

[0038] The pressure and acidic gas generated inside the first pickling solution storage tank 310 and the second pickling solution storage tank 320 during operation are discharged through the exhaust ports 313 and 323 above and the discharge pipe 600 connected to the exhaust ports 313 and 323 .

[0039] After pickling in the pickling module, the welding wire 1 enters the copper plating module 400, and the copper plating module 400 is provided with a first copper plating liquid storage tank 410 and a second copper plating liquid storage tank 420 for separate use (i.e., a two-chamber copper plating liquid storage tank, one for use and one for backup). Independent lifting pumps are provided above the first copper plating liquid storage tank 410 and the second copper plating liquid storage tank 420, which are connected to a common copper plating liquid nozzle 430 to form a copper plating liquid circulation loop, and the copper plating liquid is sprayed on the welding wire 1 through the copper plating liquid nozzle 430.

[0040] The copper plating liquid is sprayed on the welding wire 1 through the copper plating liquid spraying pipe 430 to perform copper plating treatment, and the spraying amount of the copper plating liquid can be adjusted by an independent lifting pump.

[0041] When the copper plating solution storage tanks 410 and 420 are in operation, the pressure and gas formed inside are discharged through the exhaust ports 413 and 423 above and the exhaust pipe 600 connected to the exhaust ports 413 and 423. The exhaust pipe 600 is connected to an external exhaust gas collection device (not shown in the figure).

[0042] The copper plating solution storage tanks 410 and 420 are both provided with separate reflux pipelines 414 and 424 .

[0043] The welding wire 1 that has completed the copper plating operation in the copper plating module enters the second water washing module 500, and the second water washing module 500 is provided with five second water washing tanks 510.

[0044] The welding wire that has completed the copper plating operation is washed in the second washing tank and then enters the subsequent drying and sizing and polishing process.

[0045] In the utility model, the upper area and the lower area of ​​the pickling tank and the copper plating tank are separated by hard partitions, and the lower area of ​​the pickling tank and the copper plating tank are separated by hard partitions to form a pickling liquid storage tank 310, a pickling liquid storage tank 320, a copper plating liquid storage tank 410, and a copper plating liquid storage tank 420.

[0046] The solution after the spray bath cannot naturally return to the lower area in a scattered manner, but must be concentrated and returned to the storage tank currently in use.

[0047] For example, if the first pickling liquid storage tank 310 is currently used for pickling, the pickling liquid after spraying and bathing in the pickling area must flow back to the first pickling liquid storage tank 310 through the reflux pipeline 314 of the first pickling liquid storage tank 310 .

[0048] The reflux pipeline 324 of the second acid washing liquid storage tank 320 should be in a closed state at this stage to prevent the acid washing liquids in the first acid washing liquid storage tank 310 and the second acid washing liquid storage tank 320 from mixing with each other.

[0049] At the same time, at this stage, the lift pump of the first pickling liquid storage tank 310 is in a working state, while the lift pump 321 of the second pickling liquid storage tank 320 is in a waiting state.

[0050] Since the upper area and the lower area have been separated by a hard partition, each pickling solution storage tank or copper plating solution storage tank faces the problem of internal pressure relief, so the exhaust port is connected to the exhaust pipe of the upper area to release the internal pressure of each pickling solution storage tank or copper plating solution storage tank.

[0051] If the second pickling solution storage tank 320 is used, the working state is just opposite to that of the first pickling solution storage tank 310. The use and working state of the first copper plating solution storage tank 410 and the second copper plating solution storage tank 420 are consistent with the use and working state of the first pickling solution storage tank 310 and the second pickling solution storage tank 320.

[0052] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above.

[0053] Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which shall fall within the scope of the present invention to be protected. The scope of protection of the present invention shall be defined by the attached claims and their equivalents.
