technical field

The invention relates to the field of equipment for producing battery lead busbars, in particular to a lead liquid supply device for casting battery lead busbars.

Background technique

In the prior art, the manufacturing method of the battery lead busbar is as follows: the mold is immersed in the lead pot, the molten lead in the lead pot flows into the busbar forming groove on the mould, and then the whole mold is lifted from the lead pot and left Lead liquid, and finally immerse the whole mold in water to cool the molten lead liquid, and finally form a busbar. In the above-mentioned manufacturing method, a large lead pot is needed, and a large amount of electric energy is consumed to keep the lead pot warm (about 33 kilowatts of electric energy per hour), so that the lead in the lead pot is always in a molten state. In addition, when the lead pot is powered off, the lead liquid in the lead pot is seriously oxidized, and waste residue is easily produced, which affects the quality of the lead liquid. Moreover, the existing method for manufacturing busbars is difficult to control in quality, and the forming effect of busbars is poor.

Therefore, it is urgent to change the manufacturing method of the existing busbar, and design a set of equipment with low energy consumption and good forming effect to manufacture the busbar.
