Problems solved by technology

But they also have the same disadvantages: the thickness of the grid is the same everywhere. Compared with the gravity casting grid, if the total thickness of the grid and the width of the ribs are the same, the weight will increase by more than 30%. For the consideration of cost and battery capacity, this The thickness of similar grids has been reduced by more than 30% (the perforated grid has been thinned by more than 50%). As a result, the strength of the grid is reduced, the support of the grid ribs to the active material is weakened, and the deep cycle life is reduced.
Therefore, the scope of application of these types of grids is limited to high-current, shallow-cycle starting batteries, which are not suitable for applications such as power batteries and stationary batteries. Absolute advantage

Embodiment Construction

[0033] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0034] A method for processing a lead-acid battery grid, comprising the steps of:

[0035] Such as figure 2 , image 3 As shown, the first step is to extrude the horizontal ribs. The upper and lower molds 6 and 7 are extruded by the horizontal ribs moving up and down and left and right. When the upper and lower molds are closed, the cavity is formed. When the grid 10 reaches the extrusion position:

[0036] (11) The cross bar extrusion lower die 7 rises, and the cross bar extrusion upper die 6 descends;

[0037] (12) The upper and lower molds for cross-bar extrusion move relative to the left and right to extrude the cross-bar 1, and the lead alloy is deformed by force and fills the cavity formed by the upper and lower dies for cross-bar extrusion;

[0038] (13) The upper and lower molds for cross-bar extrusion are separated, the lower die 7 for cros...

Abstract

A processing method of lead-acid battery grid relates to the technology field of processing lead-acid battery grid. The processing method comprises following steps: the first step is transverse bar extruding, the upper and lower molds are extruded by utilizing up-down movements and left-right movements of transverse bars, the upper and lower molds are extruded and folded to form a cavity by the transverse bars, and continuous extruding is realized by utilizing movements of transverse bar extruding the upper and lower bars; the second step is longitudinal bar extruding, and continuous extruding is realized according to the same theory of the transverse extruding; the third step is extruding trimming, a up-down trimming mold moves up and down to eliminate extruding projections and burrs of transverse bars, frames, and tabs, and a V-shaped notch is formed by extruding at the boundary of two grids. The processing method of lead-acid battery grid improves the strength and processing efficiency of stamped grids, and reduces material consumption through extruding shaping. The processing method has the advantages of continuous grids such as gravity casting and stamped grids, avoids the shortages of them, and enlarges the application field of continuous grids.

Description

technical field [0001] The invention relates to the technical field of processing lead-acid battery grids. Background technique [0002] In a lead-acid battery, the active material of the flow reaction needs to be fixed on a grid-shaped carrier supported by a lead-based alloy, and this grid-shaped carrier is called a grid. The grid itself does not generate energy. An ideal battery grid should have the characteristics of reasonable structure, light weight, corrosion resistance, low resistance, and easy combination with active materials. [0003] The commonly used traditional grid is gravity casting grid, which has the advantages of light weight, high bonding strength with active substances, simple and mature production process, but the production process has high requirements for environmental protection equipment, low efficiency, large material loss, and poor corrosion resistance. Difference. [0004] In the past ten years, expanded grids, punched grids and continuous...
