Description

technical field [0001] The invention relates to the processing of lead-acid storage batteries, in particular to a process and device for casting and welding of lead-acid storage batteries. Background technique [0002] Lead-acid batteries are secondary batteries that use lead and acid as active materials. In production and processing, it is necessary to cast and weld the tabs clustered in the lead-acid battery; [0003] In the conventional technology: a. cast welding is to place the lead ingot in a lead furnace with sufficient volume, and electric heating makes the lead ingot melt; the mold is immersed in the lead liquid, and the lead liquid is used as the medium to make the mold obtain heat energy and lead liquid for casting and welding; Lift the mold above the lead liquid level, place the cluster and melt the tabs of the cluster into the lead liquid to complete the welding and assembly of the lead-acid battery cluster. [0004] b. Welding is to put the cluster in the fix...

AI Technical Summary

Problems solved by technology

[0005] Disadvantages of conventional technology: cast welding needs to melt a certain volume of lead to ensure the supply of heat energy. During this work process, the surrounding environment consumes a lot of heat energy

And in the process of immersing the mold up and down, the lead liquid is oxidized, resulting in the loss of lead liquid

Increase the cost of lead-acid batteries

And due to the existence of the lead furnace, it is more difficult to cool the mold (cooling water cannot drip into the lead furnace to avoid lead explosion)

Cooling water must flow inside the mold, because the working state of the mold is alternating cold and hot, so the thermal stress of the mold affects the service life of the mold

[0006] At present, welding is done manually, and the work efficiency is low; automatic welding is limited to the structure setting. Currently, there is only one welding torch, and the cooling mechanism cannot be added, so the production efficiency is low.
