Embodiment 1
[0027] figure 1 It is a schematic diagram of the structure of a hand-welded grid to complete welding, figure 2 It is a schematic diagram of manual welding grid decomposition, image 3 It is a schematic diagram of the manufacturing process of a manual welding grid, Figure 4 It is a partial structural schematic diagram of the lead wire drawing forming equipment. Such as figure 1 , figure 2 , image 3 with Figure 4 Shown, a kind of manufacturing process of manual welding grid, comprises the following steps:
[0028] a. Put the raw material of the lead pillar into the heating furnace and heat it to 170℃~190℃, so that the raw material of the lead pillar is in a molten state;
[0029] b. Add the molten lead post raw material into the lead wire forming die 1a, the lead wire forming die 1a is designed with a radial input port 1b and a lead wire axis output port 1c, and the molten lead post raw material passes through the input port 1b Entering and extending to the shaft ...
Embodiment 2
[0035] A manual welding grid, comprising several lead wires 1 and busbars 2; the lead wires 1 are wire-shaped objects formed by wire drawing; the busbars 2 are provided with a number of installation holes 21; the aperture size of the installation holes 21 is The same diameter as the lead wire 1; the plurality of lead wires 1 are inserted into the mounting holes 21 provided on the bus bar 2 one by one, and the plurality of lead wires 1 and the bus bar 2 are fixed together by welding; the plurality of lead wires 1 All are relatively perpendicular to the fixed position of the bus bar 2; the bus bar 2 is formed by mold casting, and the installation holes 21 are arranged at equal intervals; the section of the lead wire 1 is elliptical, and the major axis of the section is 3 mm to 4 mm, and the minor axis 1.8mm ~ 2.2mm.
[0036] Through the observation of the crystal phase structure, the data shows that the density of the battery grid manufactured by the above method has been greatl...
Embodiment 3
[0038] A battery, including the hand-welded grid described in the second embodiment, the hand-welded grid is manufactured by the manufacturing process described in the first embodiment. The inventor believes that since the grid is used in the battery as a prior art, its working principle and structure will not be described here.
