Description
Technical field
The invention belongs to battery and manufacture field, relate to a kind of manufacturing process and manufacturing equipment of lead acid accumulator plate grid.
Background technology
Grid plays a part carrying active material and conduction in polar plate of lead acid storage battery, and the gauge of grid has determined the amount of its active material that can carry, and the planform of grid affects grid and the bond strength of the active material that carries.At present, grid for lead-acid storage batteries is mostly plane grid, so-called plane grid is that the inner rib thickness of grid equates with slab lattice thickness or about equally, whole grid is porous flat plate shape, the grid of this plane makes active material attached to it be divided into some approximate independently unit by rib and frame, due to reasons such as the bending in the dry contraction of active material and use procedure, vibrations, the bond strength of active material and grid is lower, thereby easily causes coming off of active material to affect battery.In addition, because the full-filling thickness of active material can only exceed 0.1～0.2mm of grid face, therefore the full-filling amount of plane grid active material is less, if increasing active material full-filling amount, wish needs to increase slab lattice thickness, the increase of slab lattice thickness and weight can make the full-filling ratio of active material decline, and the method for this increase active material can not meet the demand of high-performance power type or the production of accumulating type lead-acid accumulator.
In order to increase full-filling ratio, people are studying a kind of Curved-surface grid, attempt, on the basis of plane grid, grid flexural deformation is formed to curved face type grid, the integral thickness of curved face type grid depends on crooked maximum height, thereby curved face type slab lattice thickness is greater than rib thickness, under the constant prerequisite of grid dimensional weight, its active material full-filling amount will be far longer than plane grid, and because the curved shape of grid makes active material to be interconnected and to be formed an integral body by sweep, strengthened the bond strength of active material and grid, curved face type grid is a kind of mode of optimizing structure that increases active material full-filling ratio and guarantee to have between active material and grid good bond strength.
At present, curved face type grid is a research direction, and the manufacturing equipment of existing plane grid can only complete the manufacture of plane grid, and it can not complete the manufacture of curved face type grid, there is no at present the manufacturing equipment of curved face type grid.If while adopting punching mode to manufacture Curved-surface grid, the stress influence being out of shape by bending in forming process can change original size of grid, although can be before brake forming pre-compensation, but because of interrelated between flexural deformation degree and grid precompensation size, need repeatedly test and can determine its amount of pre-compensation, its scale error is difficult control more greatly and extremely; In addition, battery manufacture is at present to low consumption, efficient future development, the making of grid has become the main flow of current grid development continuously, continuously in the brake forming process of grid, adjacent twice brake forming meeting produces mutually to be interfered, and makes in type part again produce interference deformation, affects the geomery of molded part.It is therefore, a kind of that rationally Curved-surface grid manufacturing process and equipment become the key that high-performance curved face type accumulator plate is manufactured efficiently.
