Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0026] see figure 2 , is a schematic structural view of the lead parts of the lead-acid storage battery provided by the present invention.

[0027] The lead parts of the lead-acid storage battery include a column head 12 and a butt welding piece 13 . One end of the two is provided with a pointed head 21, and the side is provided with a flying wing 22.

[0028] In particular, concave limiting grooves are further provided on opposite sides of the flying wing 22 to form an "M"-shaped edge.

[0029] Please also see image 3 and Figure 4 , image 3 It is an assembly diagram during the implementation of the welding method for the lead parts of the lead-acid battery ...

Abstract

The invention provides a welding method of a lead component of a lead-acid storage battery. The welding method of the lead component of the lead-acid storage battery comprises the steps of providing of polar plates, comb plates and a pressing strip, assembling, providing of post heads, butt joint parts and liquid lead, fusion welding, cast welding and the like. By adoption of the welding method ofthe lead component of the lead-acid storage battery, the problems that in the prior art, the lead consumption of a lead-acid storage battery is large, the internal resistance of the battery is large,and consequentially the large current discharging performance is affected are solved.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to a welding method for lead parts of lead-acid batteries. Background technique [0002] Lead-acid battery has been developed for more than 100 years, the performance of the battery is becoming more and more mature, and the structure is basically fixed. The general structure of the battery mainly includes: battery tank, cover, pole group, terminal and so on. Lead parts such as terminals in the battery of the prior art are mostly welded to the tab side by bus bars, such as figure 1 shown. This structure leaves a space for welding on the top of the lug, which is convenient for production, but the use of lead is large, and the internal resistance of the battery is large, which affects the discharge performance of high current. Placing lead parts on top of the lugs alleviates this part of the problem, but soldering does not work. Contents of the invention [0003] In order to sol...
